The absence of a princess in the princess mansion does not seem to have any impact on Gu Huai's life. The area where he moves is still only the small building and the road out of the mansion. Thanks to Baoyue's honest duty, those who originally snooped and scrutinized

The gaze has almost disappeared now.

After breakfast, he left the small building as before, and walked out of the house with the maid who looked colder than before. Gu Huai walked along the street to admire Jiang Ning's resurrection in the morning light, and followed the address given by Qian Lao yesterday.

Arrive at Dongcheng.

He was shocked as soon as he arrived. Even though there were usually many wealthy people in the teahouse, Mr. Qian didn't look inconspicuous at all, but this house with an extremely large area showed that Mr. Qian was not a simple person.

After handing over the name card, Gu Huai was welcomed in by the concierge before the announcement was made. It seemed that Qian Lao had ordered him. He passed through the exquisite and compact courtyard and not long after, Gu Huai saw the stone table in the garden.

Sitting money is old.

At this time, Mr. Qian was reading a book. He was a little different from his usual casualness in the teahouse. He still had some authoritative majesty. When he heard the voice, he turned his head and pointed to the other side of the stone table as a gesture.

The scholar in the green shirt sat down with empty hands.

"When talking about the plague yesterday, I actually picked up a medical book that I hadn't read for a long time. This medical book was brought from the Imperial Medical Office. I didn't notice it in the past, but now it seems that there are many omissions..."

In ancient times, there were a lot of red tape when visiting friends, especially when younger people met their elders. However, Mr. Qian acted casually, and Gu Huai didn't understand this either. After sitting down, he smiled and said:

"Mr. Qian was once an imperial physician?"

"I have wasted most of my life in it, and my health deteriorated a few years ago, so I retired."

"waste?"

"There are too few opportunities to check the pulse, but I have a lot of time to study pharmacology, but after all, studying medicine is to save more people in the world." Mr. Qian shook his head gently, "Now that I think about it, instead of trying to persuade His Majesty not to take those golden elixirs...

It's better to take the pulse of those people who can't pay the medical fee and have to wait for death."

Gu Huai was deeply touched: "Mr. Qian...is indeed a doctor with a benevolent heart."

"I once had a serious illness when I was young. I went through all kinds of troubles and life and death. Finally, I met a wandering doctor and saved my life. I originally wanted to take the imperial examination, but then I started studying medicine. That kind of pain and torture,

Now that I think about it, I still feel scared, and I really don’t want to let others bear it anymore.”

This kind of motivation for practicing medicine is probably the purest and noblest. Gu Huai couldn't help but respect the old man in front of him.

He has seen the poorest common people and the richest emperor, entered shabby huts, and walked through the palace halls. But this old man, who knows all about the wealth and suffering in the world, still just wants to make the world less crowded.

Some illnesses.

No wonder he felt so sad about the plague yesterday at the teahouse.

He thought for a while: "Since there are errors and omissions in the medical book, why doesn't Mr. Qian compile a new one?"

Mr. Qian put down the medical book and laughed: "I am seventy-three this year. I am already old and have more energy than I can do. Secondly, the difference in medical books in the world is just the number of prescriptions and different dosages. The medical books of the Imperial Medical Office have been compiled for nearly 10 years.

In the past twenty years, almost all the prescriptions in the world have been included. It is said that it is an omission, but in fact it is just an improvement of the prescription."

Probably realizing that the scholar in front of him didn't understand medicine at all, he continued to explain: "The land is rich in resources, and there are countless medicinal materials. No one can figure out which kind of things can cure which diseases. The so-called doctors only follow the previous methods.

The medical theories left by human beings are just constantly being improved. To re-compile medical books is too fanciful."

When a servant served tea, Mr. Qian stopped talking. Gu Huai picked up the teacup and said thoughtfully: "So that's it...then why not compile a book, a book that includes all the botanical medicinal materials and their correct usage?"

Compared to medical books that only record prescriptions, wouldn’t this move have a long-lasting impact?”

The crisp sound of the tea cup falling to the ground came from the side. Gu Huai turned around and saw that Mr. Qian, who was calm and relaxed just now, was now sitting on the spot.

He was still holding the tea cup halfway and said to himself: "Don't remember the prescription, just the medicinal materials? If all the medicinal materials are classified into categories, wouldn't the medical theory be clear at a glance? This move can be said to benefit the people. Why didn't I think of it before?

...No, there are so many medicinal materials in the world? It would take me my lifetime to collect them all..."

He stood up suddenly: "No, even if I can't make it in time, there are still descendants! If one generation can't do it, then two or three generations! From now on, when doctors all over the world prescribe medicines, they all have pharmacological basis!"

This action startled Gu Huai. He never expected that Mr. Qian would react so strongly. Before he could persuade Mr. Qian to calm down, Mr. Qian had already grabbed him by the arm with bright eyes as if he was decades younger.

Sleeves, voice trembling:

"This one thought is better than checking my pulse thousands of times! I have thanked you on behalf of all the doctors in the world. From today on, I will open a new medical book, and the name will be chosen by you!"

Gu Huai retracted his sleeves without leaving a trace and smiled: "How about "Compendium of Materia Medica"?"

"What a name! I'll start writing now!"

Seeing Mr. Qian excitedly rushing to the study, Gu Huai stopped him in a dumbfounded voice: "Medical writing is not something that happens overnight...Did Mr. Qian forget about the plague outside the city? I came here today to discuss this matter with Mr. Qian.

"

Mr. Qian was startled: "But there is really no cure for 'Pimple Plague'..."

"Nothing is certain, but some experiments are still needed."

"Master, do you need a medical kit?"

"No," Gu Huai recalled the book that had been read many times:

"Are there any oranges?"

…

Watching from a distance, Gu Huai and Mr. Qian packed up the chess pieces and played the second game. Qingming, whose figure was completely hidden between the eaves, withdrew his gaze and smiled to himself.

I actually thought he really had some way to deal with the plague... I didn't expect to spend the past few days either playing chess or chatting.

Nearly half a month has passed since he first came to Qian's Mansion. Gu Huai has clearly never touched any medical books, nor has he seen patients outside the city. Now that he thinks about those boasts about Haikou... it's so

ridiculous.

Probably because of the distance, the words carried by the wind were a little unreal:

"The young master's words of 'sutting up the wound after the operation' really benefited me a lot. The miracle doctor Hua Tuo once incised and debrided the patient's wound. However, he suffered from the incision taking a long time to heal, so he rarely used this method. If he could use a needle and thread

Stitch..."

"Mr. Qian also reminded me that the purification of spirits, in addition to disinfection, is also a good business..."

"I have already invited some old friends. After hearing about the book, several people have replied to me. I should be able to start writing soon..."

"I'm afraid it will take many years."

"It's all about human effort. I just regret that I didn't have the whims and whims of the young master when I was young. Otherwise, why have I wasted so many years..."

After the chess pieces fell, an old man and a young man were still chatting. Qingming felt a little irritated, which was very rare given her temperament. Just when she wanted to turn around and leave, the two people at the stone table suddenly made a move.

"Calculate the time, it's almost time."

"I still don't understand what the young master wants to do."

"What did Mr. Qian say? I don't know how many times Mr. Qian has given me advice these days. Without Mr. Qian, how could this good medicine be available?"

"Young Master is here again...I have obviously done nothing, so why are you always surprised and asking me for advice?" Mr. Qian was a little helpless, "I have been practicing medicine for forty or fifty years, and I have never seen such a weird prescription.

..."

Even so, he still asked a few servants to bring the clay pots he had made according to Gu Huai's instructions. When he opened them, there was clearly visible mold inside.

The plum rain season has just passed, and mold is not uncommon in Jiangnan, but Gu Huai looked satisfied and looked at it carefully:

"Use oranges to produce mold in a warm and humid environment, and then use rice soup as a culture medium to let it grow for a few days..."

He scraped out some mold, put it into a plate, mixed it with the prepared vegetable oil and stirred it for a long time. He gently skimmed off the turbid liquid on the surface. Gu Huai looked at the transparent solution at the bottom and breathed a long sigh of relief.

Qian Lao, who had been watching from the side, asked: "What is this?"

"A home-made antibiotic," Gu Huai explained, "can also be understood as some kind of miracle drug... Of course it cannot cure all diseases, but it is indeed very powerful."

Mr. Qian shook his head gently: "If you are my disciple, you will inevitably be told that you are not doing your job properly."

"What are you talking about, Mr. Qian? This was clearly done under your guidance," Gu Huai said with a shameless expression, "As promised, if we can really cure it, Mr. Qian, you have to come and help... Of course, cure it.

You can't run away even if you die."

Knowing that Gu Huai's last sentence was a joke, Mr. Qian was a little bit dumbfounded, but when he saw the scholar in blue putting away the solution, he became serious: "Really want to go to the city gate to see it?"

"Without clinical trials, how can we know whether the plague can be cured?"

"The city gate is closed. It's okay to look around on the city wall, but if you want to leave the city, I'm afraid you won't be able to get in."

"Don't worry, I haven't decided to risk my life yet." Gu Huai shook his head gently and waved his hand:
Chapter completed!
