Xiao Yu's face was ugly when he heard this.

And the white-bearded imperial doctor dared to question Su Yun's medical skills when he saw that he was a palace maid, and he was dissatisfied, but in front of Xiao Yu, it was not good to have a seizure, so he had to say: "Weichen's diagnosis is definitely correct, if Your Majesty has any doubts, you can ask Cao Yuan to come for a follow-up." ”

The courtyard is the head of the imperial physician of the entire Chu Palace. Needless to say, the medical skills are brilliant.

Xiao Yu was moved when he heard this: "Then someone will go and ask Cao Yuan to come and take a look." ”

The white-bearded imperial doctor saw that Xiao Yu really asked people to invite him, and he obviously didn't trust his medical skills, and he was a little embarrassed. He didn't have the courage to be dissatisfied with Xiao Yu, but just looked at Su Yun coldly.

And Su Yun didn't realize that she had offended the imperial doctor, and her attention was all on the three words of Cao Yuanzheng.

Cao Yuanzheng, could it be that person?

A moment later, a young eunuch led a young man wearing the official uniform into the hall.

"Weichen Cao Chun, I have seen my emperor, long live."

Sure enough, it was him! Cao Chun, I didn't expect to sit in the position of the courtyard at such a young age.

Su Yun saw the familiar face, but he lowered his head suddenly, for fear of being seen by Cao Chun, and the silk handkerchief in his hand was already clenched.

"Cao Aiqing is exempt, come and see why Concubine Shu has been unconscious." Xiao Yu hurriedly commanded.

Cao Chun got up as he said, took out a white silk handkerchief from the medicine box he brought, and put it on Nie Yan's wrist before asking for a pulse.

Su Yun was relieved to see that Cao Chun was focused on Nie Yan's pulse and did not see her kneeling beside her.

When he was young, Cao Chun put away his handkerchief and said to Xiao Yu: "Your Majesty, Weichen believes that Concubine Shuniang is not sick. ”

Xiao Yu frowned and said, "Why can't you wake up if you are not sick?" ”

Before Cao Chun could answer, the white-bearded imperial doctor interjected: "Wechen said that the mother should be caused by exhaustion, presumably Cao Yuanzheng is the same as Wechen, right?" ”

After finishing speaking, the white-bearded imperial doctor glanced at Su Yun who was kneeling beside him very defiantly, but Su Yun buried his head very low and didn't see his eyes at all.

The white-bearded imperial doctor thought that the palace maid knew that she was wrong, and couldn't help but be secretly proud.

But soon his pride vanished, because Cao Chun answered.

"Your Majesty, Weichen thinks that Concubine Shu should have been poisoned!" Cao Chun is colorful.

Xiao Yu's heart tightened when he heard this, and said, "What kind of poison?" Can it still be saved? ”

Cao Chun did not answer, but gave Xiao Yu a vague look.

Xiao Yu suddenly realized: "Idle people wait to retreat together!" ”

After speaking, Xiao Yu looked at the eldest prince again and said, "Yongning, you can go back too." ”

The eldest prince watched the interaction between Xiao Yu and Cao Chun, and naturally understood that this matter might involve some secrets that he was inconvenient to know or could not know. Although he was curious, he still obediently listened to Xiao Yu's words and left.

Although Su Yun was also curious, he didn't dare to stay here for a long time, and it was not a good thing to know too much in the palace. Moreover, she was afraid that Cao Chun would recognize her.

In the blink of an eye, in addition to Xiao Yu, Xu Lin and Cao Chun in the hall, there was only Concubine Shu who was lying on the bed and sleeping unconscious.

Cao Chun knew that Xu Lin was Xiao Yu's confidant, so he replied reassuringly: "This poison is called drunken life and dream death. ”

"What? Fuddle?! ”

Xiao Yu's face changed suddenly, even though after he ascended the throne, he had already practiced the habit of being happy and angry, but at this time, he couldn't hide his shock.

Even Xu Lin, who has always been ruthless, also showed an expression of disbelief.

This drunken dream and death first appeared in the period of the first emperor, made by the imperial hospital at that time, Xu Chengfang, and only used this medicine on one person, that is the prince who once failed to rebel, Xiao Che!

The first emperor was a father after all, and since he couldn't avoid putting Xiao Che to death, he wanted Xiao Che to die without pain.

Only then did Xu Chengfang develop a painless poison.

Drunk and dreaming of death, Xiao Che died in countless dream bubbles.

And Cao Chun was the disciple of Xu Chengfang, who was the head of the academy back then, if he hadn't read all the notes of his master, he wouldn't have been able to name the poison that Nie Yan was in now.

But Cao Chun only knows one and doesn't know the other, otherwise he wouldn't be so calm.

Xiao Che's death, Cao Chun didn't know. He only knew that drunken life and dreams of death were made by the master.

"Is there a solution?"

Xiao Yu was the emperor after all, and after a short period of shock, he came back to his senses and asked.

Cao Chun shook his head and said, "Those who are poisoned by this poison will definitely die of poison within three days." If it had been discovered early, Wechen would still have a try, but now there is only one and a half days left, Wechen may be powerless, and ask His Majesty for forgiveness. ”

Xiao Yu had mixed feelings in his heart when he heard this, and he promised her not long ago that he would not let her suffer any more harm, and now he was about to break his promise so soon.

Think about it, how could the poison specially developed by the first emperor for Xiao Che leave an antidote? Moreover, Xu Chengfang back then, after Xiao Che's death, was also sent to Xiao Che by the first emperor to accompany him to the funeral.

"Your Majesty, Concubine Shu will definitely not be in pain when she leaves, and please mourn Your Majesty."

Xu Lin stepped forward and comforted.

Xiao Yu calmed down, not because of Xu Lin's words, but because he felt that he couldn't give up hope.

"Cao Chun, I order you to put down all the affairs you are doing and immediately go to develop the antidote to Concubine Shu. In any case, as long as Concubine Shu is not dead, you can't stop. If you succeed in rescuing Concubine Shu, I grant you a wish. ”

Xiao Yu stared at Cao Chun and said, he knew that Cao Chun had always had a wish, if he could save Nie Yan this time, Xiao Yu would not mind fulfilling him.

Sure enough, when Cao Chun heard this, he immediately knelt on the ground and solemnly promised: "Weichen obeys the order." ”

Afterwards, Cao Chun did not dare to delay for a moment, and hurried to the medicine house where the master once lived, where all the master's notes were placed, and he hoped to get the recipe for drunken life and death from there.

With the formula, if you want to detoxify, you can get twice the result with half the effort.

After Cao Chun left, Xiao Yu had a gloomy face and said to Xu Lin: "Check, this poison obviously disappeared forever with Xu Chengfang's death, how did it come out now, and how did it fall on Concubine Shu!" ”

Xu Lin heard the words and received the order, but he hesitated a little and said: "Your Majesty, let Cao Chun find the antidote, if he finds out that Xu Chengfang died strangely back then, do you want to ...... him?"

Xiao Yu suddenly realized when he heard this, Xu Chengfang did die because of Xiao Che back then.

Although the first emperor had to execute Xiao Che back then, in the heart of the first emperor, his favorite was not Xiao Yu, the son who inherited the throne, but Xiao Che, who he personally executed.

The first emperor is the king of a country, so naturally he will not blame Xiao Che's death on his head, so Xu Chengyi has become the best target for the first emperor.

So Xu Chengyi was charged with improper medication, which led to the death of a palace concubine, and not only was he executed, but his family was also exiled.

"Don't touch him for the time being, everything will wait for Concubine Shu to wake up." Xiao Yu ordered.
