A young man was lying on a fairly large tree branch. The young man's hand held a bottle of wine. "Your Highness Prince, come down." said a guard under the tree. The young man looked down at the tree and pouted.

...Feng Yichen...

...Lan Feiyu...

"I told you not to wear clothes like that. You still wear them." shouted the young man who was called the prince. "You spoil him too much." said a voice again. "First brother, if you don't come down. Then I will cut down this tree right now." said the other voice.

"Feng Muyang! How dare you threaten me!" said the young man coming down angrily. Due to a wrong step he almost fell without being elite, if not for his bodyguard catching him.

"You were the one who asked me to leave the palace but instead you got drunk here. I should be the one who was angry, Feng Yichen!" The person called Feng Muyang said coldly. "Ah, I forgot." Said the young man whose name turned out to be Feng Yichen.

...Feng Muyang...

Feng Muyang, is the crown prince of the Spring Kingdom. Feng Yichen, the eldest brother of Feng Muyang, a prince who was the former crown prince. Feng Yichen's personal bodyguard was called Lan Feiyu.

"Where are your personal guards?" Yichen asked curiously. "Are you forgot? Before I became crown prince, I was also a martial arts expert. Do I still need bodyguards?" Muyang asked massaging his temples. "I forgot, you always beat all your guards until they resign." Yichen said casually.

"Change your clothes." Yichen said looking at Feiyu. "Today, I won't be coming with you two. I have duties." Feiyu explained. Yichen looks disappointed but finally allows Feiyu to leave. The two of them quietly slipped out of the palace.

---Lan's residence---

@workspace

A young man crept in casually. "You can go through my door." Lan Feiyu said smiling. "Are you planning to make fun of me? You know I can't get through the door." The young man grumbled irritably. Feiyu smiled softly.

...Lan Feiyu...

"Why are you disguised as the Imperial Guard? I only told you to send someone to guard him. Not told you to leave your position." said the young man sighing.

"Because that's the task, my good friend handed over to me. Of course, I have to do it myself. Besides, I don't trust my subordinates." Feiyu said seriously. "A minister from the Ministry of Justice is afraid of his subordinates?" the young man said mockingly.

"Zhang Qingyuan, you were also the Vice Minister of the Judicial Court of Review, but what happened to you? I don't think you forgot." Feiyu said seriously. The face of the young man called Qingyuan was not good when the topic brought out.

...Zhang Qingyuan...

"You're right. I didn't forget. I couldn't even use my own name and had to assume the identity of a prince." Qingyuan said flatly. "So Your Highness Prince Feng Ping, what will you do now?" Feiyu asked teasingly.

"I discovered something during my visit to the Summer Kingdom." Obviously Qingyuan was serious. "The person who framed you?" Feiyu asked. Qingyuan nodded. "She didn't die. She was General Xie Ming's daughter, her name was Xie Ying." Qingyuan explained.

"So the corpse really wasn't her. Have you informed His Majesty the Emperor?" Feiyu asked. "I've told His Majesty the Emperor. He said I can handle it according to my own plans." Qingyuan explained.

"Have you thought about your plan?" Feiyu asked. "A little. I have to go now." Qingyuan said calmly. "Are you going back to the palace now?" Feiyu asked. "I have to disguise myself as Feng Ping first before returning to the palace." Qingyuan replied before leaving. Feiyu shook his head.

---road---

Yichen looked cheerful and tried various foods being sold. Muyang followed behind and paid for all the snacks that Yichen ate. In the eyes of other people who saw, Muyang looked like an older brother than Yichen.

Yichen was too busy looking at the food. Accidentally bumped into Qingyuan who was about to return to his carriage. "Sorry I did not mean it." Yichen said apologetically. "It doesn't matter." Qingyuan said. "Are you okay?" Muyang asked worriedly. "I'm fine but I crashed..." Yichen stopped because Qingyuan had disappeared.

"Be careful." Muyang said, Yichen nodded in return. Noon came quickly and the two were forced to return to the palace. This afternoon, their little brother will return to the palace after visiting many places. The younger brother they knew after Zhang Qingyuan's death, Feng Ping.

---Royal Palace---

@royal gardens

All the princes gathered there to welcome Feng Ping home. Emperor Feng Ming Tao and Empress Lu Yeruo arrived followed by Feng Ping behind them.

"This child pays respect to Father and Mother." Feng Yichen, Feng Muyang and Feng Yufei said. "Arise." Emperor Feng said. Everyone sat in their places. Feng Ping just stared at them flatly before sitting down.

...Feng Ping...

"Ping er" Lu Yeruo called but Feng Ping didn't seem to hear her. "Ping er" called Lu Yeruo once again. Feng Ping seemed to come to his senses and looked at Queen Lu. "Why did mother call me?" Feng Ping asked smiling.

"Yufei, ask yourself to tell me about your journey so far." Queen Lu explained. "I didn't get much, it's just that I tried a lot of local food. Even though their cooking is simple, it doesn't taste bad." Feng Ping replied smilingly.

Feng Ping's smile disappeared when he saw the distance. Without speaking Feng Ping stood up and pulled out the sword from the Imperial Guard's hand. Movement too fast. The sword was thrown into a wall a little far away from the garden.

A scream was heard. The Imperial Guard became alert when Feiyu arrived while dragging an assassin who was pierced by a sword in his stomach. “Feiyu, pay respects to His Majesty the Emperor and Her Majesty the Empress.” Feiyu said kneeling. "You may rise" said Emperor Feng.

"What is this?" Yichen asked confused. "It seems that a murderer broke in. And..." Feiyu's words stopped because the murderer committed suicide with poison. Feng Ping walked up to the assassin and knelt down.

Feng Ping examined the assassin's corpse carefully. Feiyu also did the same. "He hides poison under his tongue." Feng Ping said. "He seems to be a professional killer too." Feiyu added.

"He infiltrated the palace. Not long ago, dressed as a eunuch." Feng Ping said looking at Feiyu. Feiyu nodded. "Your Majesty the Emperor, I think an inspection of the personnel in the palace should be carried out." Feiyu said suggested.

"Do it. Feng Ping, you will lead this investigation." Emperor Feng said. "This child, take orders." Feng Ping said calmly. Emperor Feng and Empress Lu left after that. Feng Yufei looked angry and left. Meanwhile, Yichen and Muyang looked suspiciously at Feiyu and Feng Ping.

The way they talk and their actions show they know each other and not just that. They are very similar to two friends from the past. Even though neither of them remembered their friend's face.

"Your Highness the Crown Prince and His Highness the Prince, please return to your respective palaces." Feng Ping said. "Your Highness, we'd better go back." Said Feiyu who was already beside Yichen.

"Feng Ping, do you know A Yuan and Feifei?" Yichen asked suddenly.

"Your Highness Prince, I don't know who you mean? Then I need to check the corpse as well as this garden. So please go back to your palace." Feng Ping said coldly.

"Why? You're afraid of saying the wrong thing. You must know Vice Minister Zhang Qingyuan from the Judicial Court of Review as well as Vice Minister Feifei from the Ministry of Justice." Yichen said angrily. "One is a criminal and the other is a friend of a criminal. How do I know them?" Feng Ping said coldly.

"They're not criminals. They..." Yichen's words stopped because Muyang pulled Yichen away. Feiyu nodded at Feng Ping before leaving there. Feng Ping went back to looking for any remaining clues.

---White Palace---

"Why would he say that? He is rude one." Yichen said angrily. "Calm yourself. As long as we can't clear Qingyuan's name and his family, that will be the problem in everyone's eyes." Muyang explained. Yichen fell silent sadly.

A young man in military uniform came. “Feiyu, go help prince Feng Ping.” The young man said calmly. "Commander, but..." Feiyu was interrupted. "No buts. This is related to palace safety." The young man said and left.

"Your Highness Crown Prince also your Highness Prince, I will go first." Feiyu said leaving. "Xiao Lingyuan, never changes. He is still so cold." Muyang said flatly. "It's because Qingyuan, he became like this. He's the closest to Qingyuan. He almost took Qingyuan away. If it weren't for Qingyuan's refusal, maybe Qingyuan would still be alive." Yichen said sadly.

"Then he became a fugitive. He is Zhang Qingyuan. He is also the Vice Minister of the Judicial Court of Review. He will not be a fugitive." Muyang said looking at the sky.

"It's true, he's closer to you than to me. Even though he's my study partner, he's much more closed off." Yichen said remembering the past. "He's close to me not because he trusts me more, it's just that I will be his sister's husband in the future. He watches over me." Muyang said smiling. Yichen looked at Muyang in disbelief.

@palace road

Feng Ping sleeps against the fence until Feiyu arrives. "Get up and get off that fence. If one of the tiles falls then you will fall too." Feiyu grumbled. Feng Ping got up and sat quietly on the fence tiles before coming down.

...Feng Ping...

"You changed your face again." Feiyu said sighing. "I needed to move freely so I decided to wear this face. That one was too formal." Feng Ping said casually. Feiyu was at a loss for words.

"How is your investigation going?" Feiyu asked. "I need to enter the Imperial Guard residence." Feng Ping said steadily. "What did you find?" Feiyu asked. "You help me in and you'll know." Feng Ping said smiling sweetly. Feiyu grinned slightly.

@Imperial Guard residence

The imperial guard has a house outside the palace but most of their time is spent in the palace to maintain palace security.

“Feiyu, you are back.” said a soldier. "Yes, is your shoulder better?" Feiyu asked. "It's more better now, who is this?" asked the soldier. "My friend, he said he wanted to enter the Imperial Guard. I took him to have a look." Feiyu explained.

"Then I'll tell you. Don't join Yuan Le Yang's group. They're not good people." The soldier said looking alert. "How can it be?" Feng Ping asked calmly.

"I can't talk any longer. Feiyu can tell you more information. I have to meet Commander Xiao first." The soldier said leaving. "Let's search first." Feng Ping said.

The search went smoothly. "Whose bed is this?" Feng Ping asked standing still where he was. "Hu Zaichun. One of Yuan Le Yang's confidants." Feiyu explained.

"Feiyu, I need you to immediately check this person's whereabouts. Don't let him escape." Feng Ping said. Despite his doubts, Feiyu immediately left. As soon as Feiyu left, Feng Ping opened the board and took out the book inside quickly.

Simultaneously dozens of arrows were shot. The board is like an unlocker for traps. Feng Ping managed to escape dozens of arrows but the last arrow managed to injure his shoulder. Feng Ping immediately ran away.

The residence immediately became chaotic. Feng Ping withdrew the arrow from his shoulder and threw it away before hastening his steps. The Imperial Guard immediately gave chase, causing Feng Ping to jump into a palace that belonged to who knows who.

Feng Ping fainted after that. When he woke up again, he found that he was lying down and the wound had also been bandaged.

"Now you tell me. Who is he?" Yichen asked angrily. "I already said he is prince Feng Ping." Feiyu explained. "I'm not senile yet, I remember my brother's and his faces are different one." Yichen protested.

Feng Ping sat on the bed and looked at the two who were still arguing. Feng Ping's face was quite pale. Without caring about Yichen and Feiyu's argument. Xiao Lingyuan came in carrying clothes.

"Your Highness Prince, you are awake. These are your clothes." Lingyuan said calmly. "Commander Xiao, does father have any orders?" Feng Ping asked weakly. "His Majesty the Emperor ordered you not to wear any more disguises when you are in the palace. It would be dangerous if people don't recognize His Highness the Prince." Lingyuan replied.

"I understand. I will use my real face." Feng Ping said quietly. "Are you better?" Feiyu asked worriedly. "I am alright." Feng Ping said smiling softly. Lingyuan immediately left without saying anything.

"Can't he say goodbye? There are no rules." Yichen grumbled in annoyance before looking at Feng Ping. "Are you really my little brother, Feng Ping?" Yichen asked about to pinch Feng Ping's cheek but Feng Ping held his hand.

"If you pinch me instead of getting better it will get worse." Feng Ping explained. "Where did you learn to disguise yourself?" Yichen asked suspiciously. "From my teacher. I'd better go back to my palace." Feng Ping said quietly.

"Why? You're afraid I'll find out the secret." Yichen asked. "No, but outside your person has arrived. Maybe he has information for you." Feng Ping said standing up. Yichen fell silent. Feng Ping took the clothes brought to him and walked away followed by Feiyu.

"Come out." Yichen said to his spy. The spy came out. "Your Highness, he really is your younger brother. I've checked the available data. His mother died not long after giving birth because his body was weak when he was 5 years old. He was sent to the temple so that his condition would improve. The day he came back, it should be Zhang Ruo Xuan who brought him home But master Zhang died so he came back alone." Obviously the spy named Li Ming.

"Find out who Feng Ping's art of disguise teacher is." Yichen said firmly. "Understand." Li Ming said before leaving. "I hope you're not a spy sent to hurt someone important to me." Yichen said sighing. Yichen is suspicious of Feng Ping's identity.

---Leaf Palace---

Feng Ping sat in a chair. "Are you okay?" Feiyu asked worriedly. "I'm better." Feng Ping said seriously. "You two should be more careful." Feng Ping added looking at Lingyuan and Feiyu seriously.

"Why? Is it because of Yichen?" Feiyu asked. "Didn't you see? He is suspicious of Feng Ping's identity." Lingyuan replied calmly. "He's still investigating my case now. So he has an organization to investigate this. If we're not careful, we'll get caught." Feng Ping said calmly.

"I feel like you've changed a lot." Feiyu said seriously. Feng Ping laughed softly. "If I were still my old self. Maybe I would have died in their hands. Getting carried away by emotions would destroy our hard work." Feng Ping said calmly.

"You've grown up." Feiyu said ruffling Feng Ping's hair. "Put your hands away!" Feng Ping said irritably. "You are all here." Yichen said coming in.

Lingyuan, who had already stood up, stared at Yichen silently. Feng Ping stared at Yichen in disbelief. Meanwhile, Feiyu was quite shocked to see Yichen come.

...Xiao Lingyuan...

...Liang Yuze...

"You three know each other?" Yichen asked smiling. "That..." Feiyu's words were interrupted by a scream. "Young Master, I found the book you left behind." Said an excited young man coming.

"First brother, I have something to do. You guys talk." Said Feng Ping stood up and entered his residence. Lingyuan did not speak and left. "So what happened?" Yichen asked seriously.

Feiyu sighed before speaking. "Lingyuan was sent by His Majesty the Emperor to check on His Highness Prince Feng Ping's condition. I lived near the temple since I was little. His Highness Prince often went out to play and we became friends." Feiyu said calmly.

Yichen fell silent. 'He's not lying. Am I thinking too much?' Yichen thought. "These few days, you stayed here to look after Feng Ping. I was worried that someone would kill him." Yichen said seriously. His eyes showed concern.

"Thank you, first brother. But there's no need. I'm fine." Said Feng Ping who came out. "Is your body okay? Your wounds are quite deep." Angry Yichen was annoyed. "I'm still standing in front of you so I'm fine. But I don't think you will be fine. They might mess up your palace to find what they want because I passed out at your place." Feng Ping explained.

"They felt you would leave it at my place." Yichen said seriously in response to Feng Ping's nod. Yichen immediately ran away followed by Feiyu after Feiyu grinned at Feng Ping. "Do not change." Feng Ping said looking at the sky.

"Yuze, arrange a meeting in two days." Feng Ping said calmly. “You are really going to bring Young Master Lan there?” Yuze asked, Liang Yuze, the young man who came with enthusiasm.

"Lingyuan has gone there. He also has to go. You also know, it's not safe anywhere. It's safer there." Feng Ping said. "Young master, don't you even trust Prince Yichen? I think he's a good person. There's no way he..." Yuze was cut off.

"Yuze, we don't know what's in a person's heart. Maybe he's involved or not. But I can't allow even the slightest mistake. I've lost a lot of people. I don't want to lose you or Shadow. So I don't trust anyone other than you, shadow, Lingyuan and Feiyu too." Feng Ping said looking at the sky.

'I don't want it for my sake. He sacrificed even more. He has lost his position, therefore, in order to protect my sister, Muyang must accept his current position. They both have lost a lot. One loses power and the other loses freedom.' Feng Ping thought silently.

---Moonlight Palace---

Yichen thought about what Feng Ping said seriously. "What is Feng Ping hiding here? Has he taken it?" Yichen asked suddenly. Before Feiyu managed to answer.

"Seeing someone say that finding it means it's taken. Young master? Why doesn't that person address Feng Ping as prince?" Yichen muttered thoughtfully. Feiyu smiled looking at Yichen.

Yichen could be said to be quite a smart and thorough person. 'A Yuan is right. If we're both not careful then we'll be found out.' Feiyu thought smiling. "Feiyu, can you find me some information about the past few years?" Yichen asked suddenly.

"Information about what?" Feiyu asked confused. "Personnel from the Judicial Court of Review are also the Minister of Justice." Yichen explained. "Your Highness Prince, what do you want to do?" Feiyu asked seriously. "I want to find my friend. He might be able to answer my questions." Yichen answered seriously.

"I know you want to use the Imperial Guard to get that information but I'm sorry. I can't do that." Feiyu said flatly. Yichen was quite shocked. This is the first time Feiyu has flatly rejected his request.

"Why? You can borrow it for a while before returning it." Yichen said he didn't accept it. "What do you want to steal, first brother?" Muyang asked coming with a sour face. "Information about the personnel of the Judicial Court of Review as well as the Minister of Justice." Feiyu replied. "Traitor. How dare you tell Muyang!" Yichen shouted angrily.

"Are you tired of living? You still want to get the personnel list of those two departments. Did you know? That's an offense for Feiyu and he will likely be beheaded. You will probably be expelled from the capital." Muyang said flatly. "I just want to look for Feifei. I might find out some things." Yichen explained.

Lan Feiyu was silent when he heard Yichen's words. "Isn't it easy to find Feifei? Look for Xiao Lingyuan." Muyang said calmly. "You're right. I'll look for it tomorrow." Yichen said excitedly.

"Why did you come here?" Yichen asked confused. "I came to see Feng Ping. Is he still inside?" Muyang asked. "He has returned to his palace." Yichen replied. "I'm staying here tonight." Muyang said flatly.

"Why suddenly? Aren't you looking for Feng Ping?" Yichen asked seriously. A small letter was given by Muyang to Yichen. "Guard Moonlight Palace." Yichen muttered reading the writing. "Why does this writing look familiar?" Yichen added.

"The letter was tied to the arrow that was shot. I thought at first it was because Feng Ping was here. It seems that it wasn't because of Feng Ping. The writing was Feng Ping's." Muyang explained. "Why do you know?" Yichen asked confused.

"I've seen a letter he wrote to Father. So I recognized his writing. Our little brother is not an ordinary person. Maybe he will give us an extraordinary surprise." Muyang added. "He is indeed not an ordinary person. A person with injuries that are not light can return to his own palace where is not short distance away." Yichen said.

'Not only Yichen but Muyang also cannot be underestimated. We have to be more careful.' Feiyu thought calmly. "Feiyu, you said you were friends with Feng Ping since childhood. Why didn't you tell him about your childhood?" Yichen said suddenly.

"Your Highness Prince, why are you suddenly interested in this servant's childhood?" Feiyu asked smiling. Yichen cleared his throat. Yichen looked awkward. Feiyu was clearly teasing Yichen. "Because my eldest brother likes you." Muyang said casually.

"What are you saying?" Yichen said hitting Muyang's shoulder in annoyance. "Your face says it all. I still need to say it." Muyang said casually. "I don't." Yichen said, refuting Muyang's words.

"Why don't you talk?" Yichen asked looking at Feiyu. Feiyu looked at the sky silently. Muyang and Yichen also looked up at the sky. "Eagles, the only army that uses eagles is the Qi family border army. Why are there eagles here?" Muyang said speechlessly.

Feiyu looked at the eagle flying by. "I heard that General Qi Gang's son Qi Zhiyuan and his wife Qi Lihua will return to the capital to celebrate the Spring Festival." Yichen said calmly.

"I think this year, Xiao Lingyuan will take time off." Muyang said smiling. "Of course, big sister came back after so long. It's just, it's very strange. They came back because of the edict issued by father." Yichen said seriously.

"The edict only told them to return to celebrate the Spring Festival in the capital. I think there is another reason behind their return. Because the Qi family is free to enter and exit the capital without restraint except for General Qi Gang." Muyang said looking at Yichen seriously.

"It's been 3 years. The Qi family never returned to the capital. This year's return, I think the eagle was to tell Xiao Lingyuan that they were home." Yichen said. "3 years ago, what should have been a happy day became a day of death for the Zhang family." Yichen added sadly.

Three years ago, a week before the Spring Festival. Qingyuan was accused of murdering a woman, not only that, betraying the country was also placed on his head. Two days after that, Zhang Ruo Xuan, Qingyuan's father, was found hanged. Two days before the Spring Festival started, Qingyuan's mother Li Hua was found hanged as well. The night before the Spring Festival, Qingyuan was given poisoned wine and died.

The only person who survived was Zhang Xiahui, Qingyuan's younger sister who was at the temple after being sent away by Zhang Ruo Xuan to pray. Zhang Xiahui had already left a month before Qingyuan got into trouble.

Everything happened too quickly and the Minister of Justice decided it was too hasty. So Yichen and Muyang were not satisfied with this decision. Yichen openly resisted and the position of crown prince was revoked. Muyang is different, Muyang is secretly investigating this matter.

But also did not find strong evidence to declare Zhang Qingyuan innocent. The regret they both had was not being able to clear Zhang Qingyuan's good name until now.

"I heard that this year prince Haoran also came back." Feiyu said suddenly. "That's right, by imperial decree. Otherwise, he wouldn't have come back. He was the most angry about A Yuan's death." Muyang said calmly. Feiyu nodded.

Night fell, Feng Ping's guess was correct. Several people infiltrated the Moonlight Palace. Some of those people were kicked out of there. A fierce fight took place.

---Leaf Palace---

Feng Ping was fighting with someone who covered half his face with a cloth. The fight was stopped because a firework signal was seen coming from the Moonlight Palace. The assassin immediately withdrew from there. "That's bad!" Feng Ping said immediately heading towards the Moonlight Palace.
