Su Zixuan is still thinking carefully here. She doesn't realize that she hasn't seen Chu Yixuan.

She thought of all kinds of people in the palace, but she had no clue.

Is it really the queen?

Chu Yixuan was in the palace at this time. He came with anger, but he didn't know what he remembered on the road. At the moment he saw the emperor, he became full of grievances.

Of course, the news of Su Zixuan's poisoning didn't spread so fast, but Chu Yixuan couldn't help entering the palace as soon as he knew it.

So when he stood next to the emperor, the Emperor didn't know what had happened, but he still had such a wronged and distressed expression.

"What's the matter with you? How can you look like this?" the emperor said with a little teasing. In fact, their father and son get along much more easily than with other princes, and he has the most tolerance for Chu Yixuan.

But this is relative. As long as these princes don't covet his throne, he will be better to his son.

"Su Shi fell to the ground as soon as she left the palace today. My son wanted to ask what she did today and was harmed like this." Chu Yixuan said, his words were not soft, but they properly reflected his unwillingness and anger, but did not appear to be blind and dignified.

The emperor became serious when he heard the speech. "What's the matter with her? Tell me carefully."

Chu Yixuan saw that the emperor's face became serious and said seriously, "the son minister is still worried that Chang's mother is not satisfied with Su's family today. Where did he think that the people of the Su family suddenly came to the door and asked the younger martial sister to go to the Su family to treat people."

"As soon as the minister heard it, he immediately made a sound for inquiry. Only then did he know that there was something wrong with Su's family. Her face became very bad after she left the Palace door. When she arrived at the Su family, people fainted before her feet fell on the ground."

"The minister followed the younger martial sister and hurried to know that she was poisoned," Chu Yixuan said with heartache on his face. "I don't know what kind of person has such a vicious mind and uses the poison of drunkenness."

"Drunk hazy?" the emperor asked, "are you sure she is drunk hazy?"

"Yes, younger martial sister diagnosed it herself. There is nothing wrong." Chu Yixuan said firmly.

"This poison is colorless and tasteless. People of traditional Chinese medicine won't know it at all. They just can't wake up after falling asleep. People are asleep, but their brains are still awake." the emperor said the medicine of this poison. When the first emperor was in the palace, this poison appeared in the palace, but there was no warning, so people can't investigate and deal with it.

"If she was poisoned like this, she would be no different from ordinary people before she fell asleep. Why did she suddenly faint to the ground? It happened to be so coincidental that your junior sister could find out," said the emperor. He felt more and more wrong. These signs seemed to be arranged.

"Younger martial sister said that Su's intake of poison was very small, so it didn't matter. In addition, the medicine was probably put in the tea. It changed its drug properties and made it in advance." Chu Yixuan answered like a stream and didn't panic about the emperor's query. After all, it was these that were diagnosed. He didn't mix half a lie.

The emperor stared at him. He didn't think Chu Yixuan was cheating him. After all, he was the emperor. No one dared to cheat and tease him, but he wanted to know Chu Yixuan's real purpose.

"Who do you doubt?" the emperor asked, adding the emperor's authority in his tone, which made people not angry.

The first thing Chu Yixuan said when he came in was that Su Zixuan had been killed, but he found himself and must be the object of suspicion.

"My son dare not, but the imperial palace courtyard is heavily guarded, but it can easily poison a person. If you don't investigate thoroughly, asking the behind the scenes to bring to justice is really asking my son to worry about the safety of my father." Chu Yixuan's righteous words are like whether he was the one who defended Su Zixuan earlier.

The emperor also thought of this. If there is such a thing in any drink, what else is safe in the palace.

When Chu Yixuan came out, it was dark. Before the key of the Palace door fell, Chu Yixuan hurried out and walked all the way to the Su family.

He is very worried now. When he saw her at Su's house earlier, he saw that she was pale, frowned and distressed, but Tao Muyun wanted to inject and detoxify her.

Chu Yixuan couldn't wait, so he hurried into the palace to ask the emperor for justice.

In fact, he can check this matter by himself, but after checking it out, he doesn't have the ability to escape the shadow guards of the emperor all over the palace and easily attack one person. Besides, he may be the head of the palace.

To find the emperor, first, in order to better deal with this matter, it is much more convenient to borrow the people in his hands than himself, and only in this way can we really control the behind the scenes.

Second, Su Zixuan's poisoning could not be concealed. When the emperor suspected himself from other signs, he might as well ask for justice immediately. After all, this is his style of the king of Jin.

No one in the palace knew what was going on. As soon as the king of Jin came out of the Qianqing palace, the emperor appointed Duke Liang to thoroughly investigate the palace, saying that he wanted to catch the murderer of the future seven princes and concubines.
