Three days later, the queen summoned all the concubines to Kunning Palace, and Chu Yan was present.

"What happened at the palace banquet a few days ago involved the murder of the royal heir. I think this matter must have a result." The queen said with a confident smile.

Chu Yan looked at Concubine Yao with a sullen face and said slowly, "The three-day deadline has come. Does Tianyao have any evidence to prove her innocence?"

Imperial Concubine Yao glanced at the Queen and said slowly, "Nan'er has found some clues about this matter. They have been waiting for you since early morning. Your Majesty, please let them in to explain."

Chu Yan nodded, and soon, Chu Younan brought Su Bei to the main hall of Yikun Palace.

"Your Majesty, my mother's maid Sang Yu will be able to leave the palace next year. My mother once promised her that she would give her a sum of money on the day she leaves the palace so that she can marry her childhood sweetheart, my cousin. So it is impossible for Sang Yu to find a partner in the palace. She must have been coerced." Chu Younan said in a calm voice.

There was a hint of contempt in the Queen's eyes. "This is the fact, and it cannot be refuted."

Chu Younan raised the corners of his lips slightly, "Father, I have sent people to Sang Yu's home. Her parents and uncle's family were all abducted, and even their neighbors were implicated."

Chu Yan pondered for a moment before saying, "This is extremely bad! Can you find out who did this?!"

The Queen did not speak. Lipin, who was on good terms with Concubine Chen, said angrily, "Your Majesty! There is a saying that goes 'the thief cries 'stolen'. Concubine Chen is bedridden due to excessive grief, and because of the poison, her foundation has been damaged. The imperial physician said that she may not be able to have children in the future!"

Chu Yan sighed heavily, "Prince Su, please continue!"

Chu Younan's eyes swept over the queen, and he said with a determined look, "Father! Although Liu Xiu's neighbors were almost wiped out, there are still two survivors. Although they don't know who kidnapped Liu Xiu's family, they said that they found something in Liu Xiu's yard that day. It is said to be a waist badge."

After hearing these words, the queen's eyes became alert, but she quickly lowered her eyes and picked up the tea bowl.

Everyone was in an uproar, but Chu Younan did not continue speaking. He just listened quietly to everyone's thoughts.

Su Bei watched from afar, muttering in his heart: This kid has only traveled through time not long ago, but he is so calm in front of the emperor and empress, and he even fooled his own mother, Concubine Yao. It seems that his acting skills are really good. I sigh that I am not as good as him!

Chu Younan also listened to Xiao Beibei's thoughts, and he immediately felt happy. Su Bei was praising him more and more and scolding him less and less, which was a good thing!

After a long silence, Chu Yan finally spoke: "Did you bring the evidence?"

Chu Younan felt that several eyes were staring at him, including Concubine Li and the Queen.

He shook his head and said, "The two survivors were frightened. They didn't speak before and only asked a few questions this morning. I haven't had time to get them yet."

After that, he continued, "That person said he was afraid of bringing disaster, but he didn't dare to throw it away casually, so he buried the badge under his bed. But this morning, Ah Bei said that he had asked some other questions. Can you let her come forward and tell us about it?"

Chu Yan's face was as gloomy as water, and he nodded slightly.

Su Bei walked forward slowly, pretending to be terrified, and knelt down with a plop. "Your servant greets the emperor! You greet the queen! The two said that a month ago, in the middle of the night, they heard a noise next door and thought it was a thief, so the couple was afraid of revenge by the thief and did not dare to go out. Later..."

She talked ramblingly, and seemed a little incoherent because she was nervous seeing the Emperor and Empress. She talked for a long time before she mentioned that the couple went out to check. At this rate, it might take another hour to get the result of the interrogation this morning.

Chu Yan didn't know which of her words was important, so he could only frown and listen.

Su Bei talked for a long time before he mentioned that a neighbor's family went to check next door early in the morning and found that the whole family was missing.

Chu Younan coughed lightly and scolded: "Speak to the point!"

Su Bei hurriedly agreed, and suddenly he spoke briefly, "A neighbor thought that Liu Xiu's family had offended someone, and reported it to the authorities, but no one in the Dali Temple accepted it. Until a few days ago, His Royal Highness Prince Su led people to investigate Liu Xiu's family. Just after asking a few questions, a man in black suddenly came to silence them. After a fight, they rescued two people. They said: That night, they heard someone talking next door, and it seemed that they were talking about a cousin, but it was vague. When they were silenced this time, they also heard the man in black talking about the palace."

Chu Yan frowned.

The same goes for the Queen.

Lipin wiped the corners of her eyes with a handkerchief, "Your Majesty! It was someone in the palace who did it! In order to harm the child of Concubine Chen, this person really committed a sin!"

The queen glanced at her coldly, and Concubine Li sobbed a few times and then shut up.

"Your Majesty!" The Queen said with a sullen face, "The so-called badge may not exist. If it is really a conspiracy, who would carry a badge?"

Chu Yan thought for a moment and said, "Prince Su, take Wang Zhi with you to get the badge back!"

Chu Younan agreed and took Su Bei out with him.

The three of them left the palace and took a carriage. When they arrived near Liu Xiu's house, they saw that the door was closed. Eunuch Wang wanted to take people in to search, but Chu Younan said, "Don't worry, eunuch. Wait a moment."

Eunuch Wang frowned, "What do you mean, my Lord?"

Su Bei snickered, "Let's go sit next door first, and the father-in-law will know later."

Although Eunuch Wang was puzzled, seeing Chu Younan's calm expression, he had no choice but to follow the two of them to the next door.

Not long after, Ling Xiao came in and said, "Your Majesty! Someone has already gone in!"

Eunuch Wang immediately became anxious and hurried out. When he came to the next courtyard, Chu Younan stopped him and said, "Eunuch, wait a moment."

After he finished speaking, he winked at Ling Xiao, who covered his mouth and nose and walked forward to open the doors and windows, then said, "The smoke has not yet dissipated, everyone please cover your mouth and nose before entering."

Eunuch Wang was puzzled, but he could faintly smell a strange fragrance coming from the room, so he covered his mouth and nose and walked forward, and saw a man in cloth lying on the side of the bed, motionless.

"It seems that he is here to steal the badge. Eunuch, have someone tie him up and take him back." Su Bei smiled with contempt.

Eunuch Wang ordered his men to tie the guy up and take him out, then ordered, "Go look for the badge under the bed!"

Su Bei smiled even more, "Father-in-law, there is no need to look for it. There is no badge in the first place."

After saying that, she turned to look at Chu Younan and smiled knowingly.

Chu Younan smiled back and nodded, "Indeed, there is no badge. We only want the person who stole the badge. But we can have someone search him. Maybe he has something important on him that can prove his identity."

Eunuch Wang then suddenly realized that this was a plot set up by the two.

He seemed to understand why Su Bei talked about a lot of irrelevant things and then spoke briefly and concisely.

"Search!" he ordered in a deep voice.

A moment later, the young eunuch ran over holding something, "Eunuch! We found a waist badge!"
