Qin Shou patted Liu Hanyu's head and said with a smile: "There is progress." ”

Liu Hanyu did not have a trace of disappointment on his face, but looked at Qin Shou excitedly and said, "Lord Wang, you are really amazing!" ”

"Much more powerful than Master."

Qin Shou smiled, turned his gaze to Cheng Chuliang, and said, "Brother Cheng, why don't you ask me to test the results of your workout?" ”

Cheng Chuliang was speechless again.

He really wanted to scold Qin Shou for being addicted to vegetable abuse.

Knowing that the two of them are not on the same level at all, they still want to try it out.

"Of course!" Cheng Chuliang walked over with a confident face, but before he could walk in front of Qin Shou, he suddenly stumbled and fell to the ground.

Liu Hanyu hurriedly ran over to help Cheng Chuliang, who made a painful expression, "Oops, hey." ”

"Lord Wang, it's really unfortunate, I accidentally flashed to my waist just now."

"It seems that there is no way to compete with the prince today."

Li Shimin looked at Cheng Chuliang's pretentious posture, smiled and shook his head.

And Qin Shou was also full of helplessness, anyone with a discerning eye could see that Cheng Chuliang was cowardly, and he didn't want to compete with himself.

"Next time, next time." Cheng Chuliang touched his waist and squeezed his eyebrows.

At this time, it was not early, and Li Shimin no longer bothered, so he simply led the eldest grandson queen back to the palace.

When leaving, Empress Eldest Sun still told Qin Shou to take care of Fang Yaoyi.

Qin Shou had no choice but to agree again and again.

Cheng Chuliang also used the excuse of back pain, asked Liu Hanyu to support him, and slowly left the palace of the king of rumors.

After walking out of the palace for more than ten meters, Cheng Chuliang straightened his waist suddenly.

It was late at night.

Qin Shou sat in the study, holding a copy of "Modern Medicine" in his hand, looking for a drug to treat lung disease.

After a night of research, Qin Shou finally selected two special drugs with fewer side effects among the seven commonly used treatment drugs.

One of them is that Du Ruhui is old, and he is afraid that other strong and effective drugs will cause other adverse effects, and the other is that because he does not know much about the detailed condition, he can only choose drugs with slow onset and few side effects when choosing drugs.

Isocyana and rifampicin are common drugs for the treatment of tuberculosis.

And the side effects are small.

"Sure enough, there are no modern instruments and means, and it is still a little difficult to treat diseases." Qin Shou got into the quilt, sighed faintly, and muttered to himself.

If there are modern instruments for examination, then it can be more suitable for Du Ruhui's condition.

Now, Qin Shou can only take his time and cross the river by feeling the stones.

Early the next morning, Qin Shou got up from the quilt, and after a simple wash, he didn't even have time to eat breakfast, so he hurriedly went out.

He first went to a Chinese medicine shop and bought some Chinese herbs.

During last night's research, Qin Shou not only studied Western medicine, but also delved into some Chinese herbs that were not harmful when mixed with Western medicine.

The purpose is to mix Western medicine with Chinese herbal medicine without anyone noticing.

After all, Heteroyancy Yuejing and rifampicin are drugs that do not exist in this era, and it is better to do it in a more concealed way.

Moreover, these two drugs are also relatively expensive in the system mall, a box costs more than fifty taels of silver, and no matter how many times they are purchased, they are all at this price.

But this price is still much cheaper than the vaccine to prevent infectious diseases.

This made Qin Shou grind his teeth a little, and sure enough, profiteers like to make money that eats human blood.

But when it comes to Du Ruhui, Qin Shou will naturally not be reluctant to give up the money, and immediately purchased a box of each, ready to try the curative effect first.

When Qin Shou arrived at Du's mansion, Du Ruhui was still resting, and the elderly, coupled with his illness, were the most prone to drowsiness.

Qin Shou didn't bother, but went to the back kitchen with the purchased Chinese herbs, and he wanted to make herbs for Du Ruhui himself.

About half an hour later, the color of the boiled Chinese herbal soup turned brown.

Qin Shou took advantage of the fact that there was no one around, quietly took out the medicine purchased from the system mall, wrapped it in paper and crushed it into powder, and poured it into the medicinal soup.

"Lord Wang, Lord Du has woken up."

At this moment, the subordinates of the Du Mansion walked into the back kitchen and said respectfully.

Qin Shou nodded, put the bowl containing the medicinal soup on the wooden plate, and said, "It's just right, I have just cooked the medicinal soup here, you can serve it to Master Du." ”

"Yes." The subordinate didn't have the slightest suspicion, and after taking the wooden plate, he turned around and left, after all, when Qin Shou was boiling the medicinal soup, he also used the excuse of boiling it according to the prescription of the imperial doctor.

And Qin Shou packed up the medicine residue after the subordinates left, and prepared to take it away from Du Mansion.

I boiled the recipe prescribed to Du Ruhui by the imperial doctor again, and after pouring out the medicinal soup, only the medicine residue was left.

Everything needs to be dealt with cleanly, so that the facts you want to cover up can be covered up.

After doing all this, Qin Shou got up and came to Du Ruhui's wing.

At this moment, Du Ruhui had finished eating the medicinal soup, and when he watched Qin Shou walk in, a trace of anger suddenly flashed on his face, "Little Li Gongzi, dare to ask how the annotation work of the bookstore is progressing now?" ”

Obviously, Du Ruhui was angry that Qin Shou was not doing his job, and he always ran to himself when he had nothing to do.

Qin Shou had already expected Du Ruhui's reaction, he poured a cup of hot water, walked to Du Ruhui's window, and said with a smile: "Lord Du, drink some water to moisten your throat, it's not too late to scold me later." ”

Du Ruhui also knew that Qin Shou was concerned about his illness, but he was not really angry, after he took the hot water, he said slowly to the people next to him: "You all go out, I have something important to discuss with Xiao Li Gongzi." ”

In the past few days, Du Ruhui no longer called Qin Shou the prince, but said that he was the son of Xiao Li.

In fact, it is also a change in Du Ruhui's mentality, knowing that his life is short, he no longer sticks to some old-fashioned rhetoric.

After seeing that everyone had left, Du Ruhui sighed and said, "Little Li Gongzi, don't toss anymore." ”

"I'm sick, I know it in my heart, it's useless."

Du Ruhui naturally knew that the medicine had been changed, of course, he didn't mean not to believe Qin Shou, because the cowpox vaccine could resist smallpox, he knew that Qin Shou knew how to use medicine.

But what the vaccinia vaccine does is only prevention, and even Qin Shou cannot cure the patient.

And the disease of lung pong is somewhat similar to smallpox, from ancient times to the present, few people can survive the disease, so Du Ruhui does not think that Qin Shou can do it.

Qin Shou smiled and said, "Master Du, how do you know if you haven't tried it, what if it's useful?" ”

Du Ruhui looked at Qin Shou, shook his head and said, "You kid, since I knew you, I haven't seen you panic, and you seem to be confident in everything." ”

Qin Shou didn't speak, but the bloodshot in his eyes said it all.

He wasn't a man of confidence, and his confidence wasn't born with it, it was a whole night of studying and flipping through it.

"Okay, I'll drink this medicine too, and you'll be relieved." Du Ruhui waved his hand and said, "Go back to the bookstore, there are still a bunch of things to deal with." ”

Who knew that Qin Shou shook his head, took the tea cup in Du Ruhui's hand, and said, "Yesterday, my father and emperor told me to stop taking care of the affairs of the bookstore?" ”
