After searching for a while, several groups of troops returned empty-handed. The leader of the imperial guards walked up to Chu Han and reported, "Your Highness, we have searched the whole palace carefully, but found nothing."

Chu Han was immediately furious. He kicked the leader of the imperial guards to the ground and angrily said, "Useless thing! Are you sure you have searched everything carefully?"

The leader of the imperial guards was angry but dared not speak. He hurriedly got up and bowed his head to apologize: "I deserve to die, but...but I have searched the palace thoroughly and really did not find anything suspicious."

Chu Han became even more annoyed after hearing this, secretly hating this group of people for being blind. The "evidence" had already been prepared in advance, how could it be missing? Are they all blind?

"Waste! What's the point of me bringing you here!" Chu Han raised his leg again, wanting to kick him.

Unexpectedly, someone interrupted him halfway. Chu Xuan threw a piece of silver and hit Chu Han's raised leg.

Chu Han was caught off guard and was hit instantly, then fell to the ground.

Chu Xuan looked at Chu Han with a mocking look on his face. "What are you doing, Sixth Brother? You are so angry just because I didn't find anything suspicious in my mansion? Are you expecting to find something in my mansion? Or have you already determined that the evidence must be in the Night Palace? What are you thinking!"

Chu Han looked up at Chu Xuan, feeling indignant. He endured the pain in his legs and slowly stood up: "Third brother, I am doing this for your own good. Father is seriously ill and there are so many people who want to harm you. I am also doing this to protect you from being schemed against. If someone wants to frame you and puts something in your yard that shouldn't be there, you won't be able to explain yourself."

"Oh? So that's it." Chu Xuan walked over, stared into Chu Han's eyes, and whispered, "Isn't this person who really cares about me standing in front of me right now? Who are you talking about, Sixth Brother? You must be disappointed that you didn't find the bag of medicine residue in my house. You have planned so hard, but it's all in vain. Sixth Brother, I feel sorry for you. Isn't it good to be an idle prince? If you don't have the brains, why do you have to learn from others to fight wits and courage?"

"You! Chu Xuan!" Chu Han pretended to be angry, but he felt a little uneasy in his heart. It was Concubine Xian who told him personally that the things were put into the palace, how could Chu Xuan know that!

And since Chu Xuan mentioned the matter of the medicine package, it must have been disposed of by now.

Seeing that his plan was exposed, Chu Han didn't want to stay here for a moment. He turned around and left in shame.

Unexpectedly, just as he was about to take a step, Chu Xuan shouted, "Shen He, stop them. No one can leave the gate of the Night Palace today!"

Shen He and others acted upon the order, and in a flash they surrounded the mansion gate tightly. The imperial guards were also captured and could not move.

Chu Han's heart skipped a beat, his face darkened, and he turned to look at Chu Xuan: "Third brother wants to imprison me in the mansion? This time I am following the order of the emperor to thoroughly investigate the poisoning. You arrested me without knowing the reason. When the emperor asks you for punishment, your brother will not defend you."

At this point, Chu Han could only pretend to be tough. He was scared to death when the emperor said that. He was afraid that Chu Xuan would get so angry that he would kill him.

Chu Xuan smiled disdainfully and stood in front of Chu Han with his hands behind his back. He felt the air suddenly stagnated. The pressure from Chu Xuan was piled heavily on him, making it hard for him to breathe.

Chu Han's face turned pale and cold sweat broke out on his forehead.

Chu Xuan said slowly, "Since Father was poisoned, then as a son, I must share his worries. You have been busy for so long, it is time to take a break. Since the search just now has proved that I am not a suspect, then leave the rest to me. I will definitely get to the bottom of the matter."

Chu Han has been showing off his might since he entered the room. Chu Xuan curled his lips, thinking that things have changed and it is time for him to fight back.

"Check? How are you going to check?" A trace of unknown panic flashed through Chu Han's heart.

At some point, the surroundings became so quiet that not even the sound of the wind could be heard, and a deep sense of uneasiness enveloped Chu Han's heart.

Chu Xuan just casually said, "When my father was in danger, he thoroughly checked all over the capital for suspicious people and objects. This is indeed understandable, but why did my sixth brother search the Night Palace when looking for the murderer? Isn't it a bit too hasty?"

Chu Xuan turned his head and looked at Lu Yanluo: "Did Ah Luo say that?"

Lu Yanluo felt amused in her heart, but she was afraid that Chu Han must be scared to death now.

"Your Highness is right. Since we have searched Prince Ye's Mansion, we should not leave out Prince Liang's Mansion either. It would be inconvenient for Prince Liang to search by himself, so let the people in our mansion take the trouble to make the trip."

Upon hearing this, Chu Xuan nodded thoughtfully.

"What the princess said makes sense. How about this, Shen He, you take your men and the brothers of the Imperial Guards to search the Prince Liang's mansion. Remember, there must be no omissions, and search carefully."

Chu Xuan spoke each word carefully, staring at Chu Han.

He knew how to torture a person psychologically and break him down.

Moreover, Chu Han must stay today because he suddenly has a very good plan, and Chu Han is a crucial chess piece.

Chu Han had never expected that Chu Xuan would be so cunning. Instead, he was outmaneuvered by him and stood there in a daze.

"You! You plotted against me!"

Shen He was very fast. Half an hour later, he returned from Prince Liang's Mansion with his men. He was holding a paper bag with a serious expression. It was the bag of medicine residue that Xiao Ran had sent out during the chaos.

Originally, Lu Yanluo and Chu Xuan planned to dispose of the drug residue secretly, but they didn't expect Chu Han to bring people over. Lu Yanluo came up with a plan to use the drug residue to make Chu Han suffer the consequences.

"Your Highness, several of my subordinates searched the Prince of Liang's mansion and found this under the bricks of the Prince of Liang's bedroom. It looks like the residue of some medicine."

Upon seeing this, Chu Han instantly lost all strength and collapsed to the ground. This was originally the result he had chosen for Chu Xuan, but he didn't expect that the situation would turn around and end up happening to him.

Chu Xuan nodded with satisfaction, took the paper package and examined it carefully. After a moment, he laughed sarcastically: "Does it look familiar to you? This is the stolen goods you are looking for, the Nanli grass. It's a pity that this stolen goods was found in your mansion. Sixth brother, how do you want to explain this matter?"

"What else is there to explain? There is solid evidence that Prince Liang plotted to murder the emperor," said Lu Yanluo.

Chu Han immediately retorted: "I didn't! You framed me. You put this thing in my house! Chu Xuan, you are so cruel!"

Chu Xuan heard this, his face that was half-smiley suddenly darkened, and after a while he sneered: "Chu Han, what qualifications do you have to say that I am cruel? Don't forget that you secretly put this thing in my house. If I hadn't found it, I'm afraid you would be the one who is aggressive now. If you do too much evil, you will eventually perish. It's been so long, why haven't you learned your lesson?"
