Bei Chenyan looked at her with some amusement and said, "You fell asleep early yesterday, why are you still sleepy now?"

"I can't do anything, either." Yun Chuchu made a race on his huge bed: "Who made my body still a little baby? Don't you know that the baby needs enough sleep??"

Beichen said: "You have been sleeping for almost twelve hours now, and it is not enough?"

Yun Chuchu turned over and sat up from the bed and said, "Oh, it's not that it's not enough, but the main reason is that these messy etiquettes are too cumbersome. I can't help but feel sleepy when I hear it..."

Bei Chenyan listened to her words and sat down next to her and said, "Actually, it's quite interesting to listen carefully."

Yun Chuchu held his chin with his little hands, looked at Bei Chenyan sitting beside him, and suddenly said, "Is there any way to let Mama Liu sleep for a while? I might be better when I have enough energy."

"Yes, sleeping pills." Bei Chenyan replied without thinking.

"There are no sleeping pills in this era." Yun Chuchu gave him a speechless look and said, "I still know how to use ether. Do you have ether??"

Beichenyan smiled, but said nothing.

After thinking about it carefully for a while, Yun Chuchu couldn't help but poke his arm and said, "Didn't you learn gene compilation? Didn't you also learn some knowledge of various diseases? Didn't you also learn some pharmacological knowledge??"

Bei Chenyan was stunned for a moment, then hesitated and said, "I have learned a little bit, but I don't learn very well."

"Then do you know what used in ancient times to make people sleep and anesthetize??" Yun Chuchu asked with anticipation in his big round eyes.

"This..." Bei Chenyan thought for a while, and then slowly said: "I remember seeing it before. It is said that 'Mafei San' is the first anesthetic invented and used in the world. It was created by Hua Tuo, an outstanding medical scientist in the late Eastern Han Dynasty and the Three Kingdoms period. In the 2nd century AD, my country had used 'Mafei San' to perform laparotomy surgery."

"There is another story that during the Warring States Period, the miraculous doctor Bian Que used "poisonous wine" to anesthetize two heart disease patients. It's a pity that there is no written record of what components "poisonous wine" are composed of."

Yun Chuchu was stunned when he heard these words: "Isn't this a modern anesthesia laparotomy and a heart transplant? Are you sure this surgery was successful thousands of years ago?"

Beichenyan smiled and said, "I don't know either, but they are called miracle doctors, so there is a basis for them, right?"

After Yun Chuchu was silent for a moment, he suddenly muttered in a low voice: "Can Hua Tuo and Bian Que also traveled through time, right?"

Bei Chenyan looked down at her and said, "Hmm??What did you say?"

"Uh, nothing, then do you know the recipe for Mafei San?" Yun Chuchu hurriedly raised his head and asked at him.

"I don't remember the specific ones very much, but the legend seems to be using mandala flowers?" Bei Chenyan said uncertainly.
