When Li Eryi heard that Li Chengqian might not have suffered from smallpox, he was immediately overjoyed and said, "Qingquan, can you really be sure that Chengqian is not infected with smallpox?" ”

"This, the minister can't guarantee it, but looking at the prince's lively appearance, I don't feel like smallpox, so let's give the prince some fever medicine first." After Zhang Nan finished speaking, he swapped out a box of white and black and a whole box of antiviral particles from the system.

"Trouble Father-in-law Liu to run away, go get a bowl of hot water." Zhang Nan said to Liu Bing at the door.

After a while, Liu Bing quickly came to Zhang Nan with a bowl of hot water.

"Master Zhang, let's see if this hot water is hot enough." After Liu Bing finished speaking, he handed the hot water to Zhang Nan. Zhang Nan took it, looked at the hot water that was steaming upwards and said, "Okay, that's it." After speaking, Zhang Nan disassembled the antiviral particles and poured them into hot water, and soon all the particles melted. Zhang Nan took out a white tablet from the medicine board and said, "Eat all this medicine and this potion, and drink all the water." ”

Li Chengqian didn't have any results and took the medicine, but Li Er curiously picked up the white and black medicine board and asked, "Qingquan, you said this thing is medicine?" ”

"That's right, it's medicine, it's very effective to cure a cold or a fever." Zhang Nan replied, hearing Zhang Nan say this, Li Er put the pill under his nose and smelled it, but he didn't smell the slightest smell of medicine.

"Qingquan, why does this medicine have no taste of medicine at all? If you want to say that the medicinal soup just now, I still believe it, after all, the color and taste are a bit similar, but is this thing also medicine? Can such a small piece cure a disease? Li Er asked strangely.

"That's right, it's medicine, and it works very well." Zhang Nan said with a smile that Zhang Nan was so sure that the effect of this medicine was good because the body resistance of a Tang Dynasty person like Li Chengqian was very low, after all, he had never been in contact with Western medicine, so the time for the medicine to take effect would definitely be very fast.

"I don't think this thing is like medicine, but like a pill." Li Er pinched his chin and gave his own evaluation.

"Your Majesty, there's nothing wrong with you saying that this thing is Dan."

"Oh? Qingquan, do you really know how to do alchemy? I knew that you would, otherwise you wouldn't have been able to see that there was something wrong with the pills refined by the fake Taoist priests in Qinglufang. Li Er said with a look of surprise.

"Okay, I will give you a month's leave, and you will study this elixir for me, and be sure to refine a non-toxic elixir." Li Er's face was full of red light.

Seeing Li Er's appearance, Zhang Nan knew that Li Er's obsession with pills had been committed again, although he and Sun Simiao had clearly told Li and the others that it was impossible to live forever, this idea was unrealistic, and Li Er also agreed with this statement, but Li Er's heart still had a little bit of luck.

"Your Majesty, the minister really doesn't know how to do alchemy." Zhang Nan said with a wry smile, Zhang Nan had nothing to do about this Li Er, who was obsessed with pills to the point of going mad. If it weren't for Li Er's obsession with pills that destroyed his body's immune system and caused chronic poisoning, Zhang Nan estimated that Li Er's current body would be longer than fifty-two years old.

Forget it by eating it yourself, and pull the eldest grandson queen, who was already in poor health, to eat with him, and as a result, he also got the eldest grandson queen in front of him and died.

"Can't do alchemy? You don't know how to make an alchemy, how can your elixir have two colors, black and white, and just now, I saw that the medicine you gave to Cheng Qian was deliberately white, is there any explanation in this? Li Er obviously didn't believe Zhang Nan's statement.

"This, there is really a saying in it, but this statement is estimated that the emperor will feel quite unreliable." Zhang Nan said with an embarrassed face.

"Oh? If you have anything to say, tell me quickly. Could it be that you want to tell me that you have to eat white during the day and black at night. Li Er guessed.

"Eh, Your Majesty, you are God, this is all right for you." Zhang Nan said with a look of disbelief.

“...... Dare to play tricks. When Li Er heard Zhang Nan's explanation, he was immediately furious.

"Wronged, Your Majesty, it's really like this, and it eats white tablets during the day and doesn't fall asleep, and eats black tablets at night and sleeps deliciously." Zhang Nan hurriedly read out the white and black advertising words.

"......" Li Er didn't say much, and slapped Zhang Nan's helmet again.

Just as Li Er, Zhang Nan and Li Chengqian were staring at each other in the dormitory, Sun Simiao's voice suddenly came from outside the door.

Sun Simiao entered Li Chengqian's dormitory, first saluted Li Er, Li Er waved his hand and said: "Sun Zhenren doesn't want so much courtesy, let's give Chengqian a medical treatment first." ”

Sun Simiao nodded, and was about to give Li Chengqian a pulse, but was attracted by the bowl on the table where Li Chengqian had just finished drinking the antivirus, Sun Simiao took the bowl and put it under his nose and sniffed it, and said with a look of surprise: "Dare to ask Your Majesty which imperial doctor in the palace prescribed this medicine." ”

After Li Er heard this, he asked, "What's the matter, Sun Zhenren?" Is there anything wrong with this medication? After asking, Li Er also glared at Zhang Nan fiercely, as if he said that if there is a problem with this medicine, you will die.

"No, no, no, there is nothing wrong with this medicine, it's just that Poor Dao can't fully identify what kind of medicinal materials are used here, and I'm just a little curious." Sun Simiao waved his hand and said.

"Sun Zhenren still asks him this question." After Li Er finished speaking, he pointed to Zhang Nan beside him.

"Oh? It seems that Xiaoyou opened it, Xiaoyou, you still said that you don't know how to heal, now it's exposed. Sun Simiao stroked his beard with a smile and said.

When Zhang Nan heard it, how strange this line was.

"I really didn't prescribe this medicine, I just borrowed flowers to offer Buddha, and I don't know what medicinal materials are used in it." Zhang Nan said with an embarrassed face.

"Oh? I don't know the medicinal materials, how did Xiaoyou decoct this bowl of medicine? Sun Simiao showed a curious expression.

"This thing is a powder, not a fried thing." Zhang Nan explained.

"Powder?"

"That's right, this is it." After Zhang Nan finished speaking, he opened a package of antiviral particles and showed it to Sun Simiao, Sun Simiao looked at the small particles in the bag, took a small pinch and put it in his mouth to taste it, and was immediately shocked, and grabbed Zhang Nan's hand, so frightened that Zhang Nan thought that this old man was going to have something super friendly with him.

"Xiaoyou, how did you make this granule, how did you turn so many medicines into such small granules without losing their medicinal properties, and I hope Xiaoyou will tell you truthfully, this is a thing that benefits all people." Sun Simiao said excitedly.
