Li Yuanming was the top surgeon in the Ming Dynasty, and his skills were perfect.

After listening to Zhao Hao's introduction to the method of section preparation, he used a special knife to cut the snail meat into slices as thin as cicada wings, placed it firmly on the glass slide, and then covered it with a precious coverslip.

It's like having been tested for many years, and it's as steady as an old dog.

It didn't take long for all thirty carriers to run out. In order to ensure maximum coverage and accuracy, the thirty slices were produced by five different snails.

As luck would have it, three of them found such a wicked schistosomiasis.

This convinced the three doctors that there was indeed a parasite in the snail.

How can I be sure that this larvae is the disease-causing schistosomiasis? There was no need for Zhao Hao to mention the 'Koch principle', and the three of them immediately thought of the experimental method based on what you said and what I said.

First, the larvae are grown in a glass Petri dish. Then, from the body of the diseased animal, the adult worm visible to the naked eye was found, and the comparison was consistent, indicating that Zhao Hao's conclusion was correct.

The age-old mystery of the cause of schistosomiasis has been completely solved.

This made Zhao Hao secretly sigh that our medical scientists are actually the best. At least in this era, our medicine is much, much more advanced than in the West. It's just that our science has not progressed, and it is just a hindrance to the doctors.

He is very much looking forward to this group of awesome medical scientists, with the help of science, where will Daming's medicine go?

After seeing the disgusting larvae, the three doctors were still unsatisfied, and asked Zhao Hao what the ubiquitous 'little poles' and 'little curly hair' were.

Zhao Hao said in a vicissitudes of tone: "That's bacteria." ”

"Bacteria?" Li Shizhen was energetic again, and hurriedly drew those strange lines on the paper. "Is it also a type of microbe?"

"Not bad." Zhao Hao nodded.

"So this ...... Can bacteria also cause disease? Li Shizhen held a small notebook and looked at Zhao Hao with curiosity.

Thinking that he could add a strong touch to the "Compendium of Materia Medica", he felt that his decision to come to Kunshan could not be more correct.

Zhao Hao was asked for a while, and felt that he needed to write "Creature" as soon as possible.

But it's very nerve-wracking just to write textbooks for students, hey, will the hairline recede if this continues?

"I'm still a child, I shouldn't have so many ...... shoulders" Zhao Gongzi secretly wailed, but he could only patiently explain to Li Shizhen and the others:

"Bacteria, like plants and animals, are a type of living organism, they are ubiquitous and diverse...... But in terms of shape, there are about three kinds of bacteria, and the 'little sticks' you see are all kinds of bacteria, and the 'little curly hairs' are all kinds of spirochets. In addition, there are various 'cocci'. ”

"Bacteria are so invisible, but they affect our lives all the time, and without the help of bacteria, we can't digest food, ferment food, and so on. However, many bacteria can also cause food to rot, wounds to suppurate, and sudden illness in humans and animals. Hundreds of diseases, such as colds, tuberculosis, plague, and so on, are caused by these harmful bacteria. ”

Zhao Hao picked up a bottle of alcohol, sucked a drop with a straw, and dripped it on the petri dish and said: "But there is no need to talk about discoloration, you can kill most bacteria with this alcohol." ”

"So when we do experiments, we must take precautions first. After the experiment, it should be cleaned and disinfected in strict accordance with the regulations. In the same way, strict disinfection in the hospital can greatly increase the survival rate of patients. ”

This is a new concept that the three doctors have never heard of. Are all those evil diseases caused by these tiny little things? It's unimaginable.

But with the trump card of the microscope, they will no longer easily question Zhao Hao.

In the minds of the three famous doctors, Zhao Gongzi must have invented the microscope for many years and used it for long-term research to come to this conclusion.

Although people cannot be superstitious about authority, it is ridiculous ignorance to question areas that they do not understand without any basis.

With the help of a microscope, we can verify all of this. The three of them said silently in their hearts.

In fact, at this moment, they already understood that Zhao Hao had opened the door to a new world for himself and for Daming's medicine.

The three healers are full of hope that this new world will solve the puzzles that have plagued them for years.

Now there is no need for Zhao Hao to keep people at all, and he can't beat him with a stick.

So they happily agreed to Zhao Gongzi's invitation and helped him run the first hospital in the Ming Dynasty.

Of course, Zhao Hao should provide sufficient support to ensure their research.

This is also what Zhao Gongzi hopes to see, and the two sides will naturally make a happy deal.

Only Zhao Shizhen knew that this microscope had actually been built for less than half a month, and his uncle had never seen it a few times.

Hey, others are inventing for the sake of exploration, but my uncle seems to be trying to prove how correct his own ideas are.

Hey, what does it mean to be born to know? What is Niu Boyi? What does it mean to be unmerely?

I'm talking about my uncle......

Coming out of Jiangnan Hospital, Zhao Hao rushed to the embankment again.

Although it was dark, the torches on the earthen embankment were lit up, and people were still busy all night.

It was Zhang Jian directing the craftsmen, debugging the installed lifting device.

Starting tomorrow, the stones will be delivered in a steady stream. Engineers can only work overtime so as not to affect the progress of tomorrow's project.

Craftsmen knew about the use of levers and pulleys to lift heavy objects 2,000 years ago, and this is explained in detail in the Book of Ink.

Inoue's reel is the most intuitive embodiment.

At this time, the lifting device is no different from the water roller in principle, which is nothing more than more load-bearing and labor-saving.

With this thing, the stones in the rattan baskets did not even have to be unloaded, and iron hooks were hung directly on the deck.

The people did not need to go down to the river, they could easily lift more than 200 pounds of stone up the embankment by shaking the winch on the earthen embankment.

The rattan basket is then moved to the crane installed on the other side of the embankment, where it is lifted off the embankment and landed directly on the cart on the inside of the embankment.

The people can directly pull the stone to the new embankment ten zhang away.

In fact, Zhang Jian also invented a crane that can turn the head, which can greatly save the labor of the embankment operation.

It's a pity that with the backward blacksmith level in Kunshan, the cast iron sleeve and inner shaft that meet the specifications cannot be made, and the craftsmen of the Ordnance Bureau are about the same.

But it is still time-consuming and laborious, and the gains outweigh the losses.

Zhao Hao asked Zhang Jian to improve and optimize the existing wooden crane first, and make do with it.

Not efficient enough? Then a few more units, it's a big deal to have a pair of them.

Anyway, there are laborers that don't cost money, and the tools are a little worse, and it won't affect the progress.

This once again proves that cheap and abundant labor is the main culprit hindering the progress of Daming's science and technology.

But Zhao Gongzi is also very helpless, the two or three hundred million peasants in the Ming Dynasty want to eat, which is the overriding top priority.

Is it to rashly engage in industrialization and replace people with machines to make the common people rebel?

Therefore, those who keep saying that Zhao Gongzi is a capitalist can take a break.

Capitalists can use machines, and they will never use people! Only an industrialist like Zhao Gongzi, who loves the country and the people, will take the initiative to tie his hands and feet for the well-being of the people.

Just thinking about it makes me feel great.

Well, it's not like he can't make it.
