When Cui Yu returned to Shaohuaju, Xiao Qi's condition did not improve in the slightest, and Qu Qianchen rummaged through medical books, but only temporarily suppressed her toxicity.

If it weren't for something in her body to protect her heart, she would have died of poison by this time.

Qu Qianchen saw that Cui Yu's front placket was stained with blood, and couldn't help but shake his head and sigh.

"Didn't I tell you not to urge internal forces? If the wound is really torn and hurts the heart, then you will suffer. ”

Cui Yu didn't answer, and only handed the book in his hand to Qu Qianchen.

"Yang Chongyuan's drug production record back then."

Qu Qianchen raised his eyebrows in surprise, "Where did you come from?" ”

This kind of manuscript is almost all private, how can it be easily found?

"The Library Pavilion of the Hall of Chapters."

Qu Qianchen frowned slightly.

Yang Chongyuan was only ten years old when he was sent as Nanzhao's proton, and he was also a student of Hanzhang Palace, so he was no stranger to Hanzhang Palace.

"Are you sure it's his transcript?" Qu Qianchen was suspicious.

"The ink is not as new, the handwriting is Yang Chongyuan's, he has a habit of writing, if he is not a familiar person, he does not know the small details of his pen."

Qu Qianchen did not question Cui Yu's words, after all, back then, Cui Yu and Yang Chongyuan were called the twin masters of the capital.

The relationship between the two is also quite good, and the children of the Jingzhong family have many evasions and few contacts with him because Yang Chongyuan is the identity of the son of Nanzhao.

But Cui Yu is not confined to the worldly vision, and interacts with him with his own heart.

It's just that too many things happened later, and the two drifted apart.

Now that Cui Yu said that the handwritten book is true, it must not be fake.

It can be determined that the little girl was poisoned by Yang Chongyuan, but what poison it is, and now he can't tell it.

Qu Qianchen took the manual, and then took out a white porcelain bottle from his sleeve pocket and handed it to Cui Yu.

"Take care of the wound yourself."

Cui Yu took it and turned his head to look at the little girl on the bed.

"If you find out what kind of poison it is, maybe it will be detoxified?"

"It's hard to say." Qu Qianchen was not sure.

Cui Yu was silent, in this world, if it is a poison that Qu Qianchen can't solve, I'm afraid that others can't.

Qu Qianchen flipped through Yang Chongyuan's handwritten notebook, and couldn't help but be amazed when he saw the refining and formula of those poisons several times.

If it weren't for the urgency of Xiao Qi's condition at this time, he would have to study the detoxification one by one.

He flipped through the pages, and the previous ones were wrong, until he turned to a page with a poison called "Nandu".

He looked and saw that Hookkiss was included, but Hookkiss wasn't all the ingredients.

Qu Qianchen had suspected that there was a hook kiss before, but he couldn't be sure that there was nothing else, so he understood at this time.

The poison of this "Nandu" is the hook kiss cultivated by various poisons, and its toxicity is still above the hook kiss.

After purification, a little bit can kill people.

"Found it!" Qu Qianchen was ecstatic.

Cui Yu was overjoyed.

However, the more he looked down, Qu Qianchen's face gradually sank.

The poisons used to cultivate the hook kiss are all highly poisonous in the world, and the hook kiss cultivated here can be said to be the king of all poisons.

It wasn't until after reading this page that Qu Qianchen and Cui Yu's eyes fell on the last two words.

No solution.

Cui Yu's heart fell to the bottom.

"Not necessarily."

Qu Qianchen's words at this time seemed to be a light in despair.

"Can you save her?" Cui Yu grabbed Qu Qianchen's wrist tightly.

Qu Qianchen brushed his hand away, this guy was now out of proportion in a panic, and his wrist was almost broken.

"Everything in the world is mutually reinforcing, and now I know what kind of poison he uses, or I can give it a try."
