Zhangxi was on the west bank of the Xiangjiang River, and finally in early March, he filled in three small lakes, sorted out a large area of tidal flats, and made out 12 hectares of fields.

Well, it's not as much as the field that Zhou Yu gave to Sun Shangxiang.

But there is no way, the time is really tight, and the manpower is small, so there is only this efficiency.

Whether the swamp can be cultivated or not depends on the effect of this experimental field.

Zhang Xi once again ordered a thousand soldiers to start farming according to the season.

In these days, the sons of the family may not necessarily know how to farm, but the people who are big soldiers are basically farmers, and there is no way that anyone will not know how to farm.

So, the spring ploughing was not affected much, and it went smoothly.

When the spring ploughing was over and the time came to April, Zhang Xi began to carry out mosquito eradication work.

Although it has been chosen as much as possible on the edge of Yunmengze, the weather is getting warmer, and there are so many mosquitoes, insects, snakes and rats in this place.

Zhang Xi now understands why the miasma is rampant in the Yunmengze area, and the breeding environment for germs is simply too good.

Not only is there a humid and hot environment, but there are also enough parasites and intermediate hosts, and it would be unscientific if this place was not plagued.

Therefore, Zhang Xi didn't dare to be careless at all, on the one hand, he had to organize the soldiers to farm, and on the other hand, he had to let the soldiers repel insects, kill rats, and catch snakes. It's very busy.

In order to ensure safety, Zhang Xi also wrote a special letter to Guan Yu in Jiangxia, asking the second master to invite Zhang Ji.

Without such an expert, Zhang Xi is fooling around alone, which is somewhat uneasy.

Zhang Ji was actually not happy to come.

At the turn of spring and summer, it was originally the season of water poisoning, Zhang Ji studied well in Jiangxia, and was observing the incidence of water poisoning after the Jiangxia government organized the people to extinguish the snails in the past two years, so Guan Yu sent two big soldiers to escort them to Changsha.

Zhang Ji was very angry, very angry.

Although I like medical skills and like to cure diseases and save people, I am essentially a child of the Nanyang family, and now the head of the Nanyang Zhang family is still my nephew.

How can you treat me so unreasonably?!

Again, as long as this summer passes, Zhang Ji can verify whether the water poison is caused or transmitted by snails, once it is confirmed to be true, it is of great significance for the treatment of water poisoning.

Well, now that the first four months of this year have been observed, another year of waiting.

So Zhang Ji is very angry, and Zhang Xi will make amends.

If you don't look at Zhang Ji's identity as a doctor, or Zhang Ji's identity as a child of the Nanyang family, just based on the age of the family, you should be respected.

The second master is too, why can't he do things so much, he is over sixty years old.

Zhang Xi bowed to Zhang Ji and apologized, said all the good things, and then talked about the purpose of inviting Zhang Ji to come - to guide the prevention and treatment of miasma.

As soon as he said this, Zhang Ji suddenly stopped being angry, and hurriedly pulled Zhang Xi and asked.

Zhang Xi told Zhang Ji about the spread of water poison through snails, so Zhang Xi said that he wanted to prevent miasma this time, and Zhang Ji immediately believed it.

After some interrogation, Zhang Ji found that this Zhang Xi was still the same as before, he may know how to prevent it, but he really doesn't know how to treat it.

But that's enough.

Zhang Ji is a real doctor, full of medical ethics, if he can prevent everyone from getting sick, he will naturally be happy to write books and write, and he will not ask about the world.

But the matter of miasma or the virus, no matter what era it is, it is impossible to completely prevent and control it, and what we can do is to do our best.

Therefore, Zhang Xi contributed all his poor knowledge of virus prevention and control, and Zhang Ji also used Zhang Xi's knowledge to start studying the possible transmission of miasma and how to prevent and control it more effectively.

Under the knowledge that Zhang Xi did not have any system, it was so easy for Zhang Ji to figure out the principle of miasma and the way it spread.

Many things can only be known as they are, but not why.

For example, miasma, Zhang Xi explained that it is a kind of invisible small insects, these small insects are transmitted to humans through some animal routes, but Zhang Ji can't understand why there are invisible small insects, how small is it, and why it can't make people sick by itself, and has to use some animals to achieve the purpose of transmission? !

Anyway, as long as Zhang Ji asks like this, Zhang Xi will be dumbfounded, and regret why he didn't study medicine in his last life.

Every time he arrived at this time, Zhang Ji would continue to look at Zhang Xi with the eyes of a loser, and then sigh and study it himself.

Really, Zhang Xi is really seriously considering now whether to get a microscope to open the eyes of this medical saint. Think about it, forget it.

Zhang Xi didn't even burn out the glass slag, let alone the qualified and usable magnifying glass lens.

Besides, now is not the time to burn glass, it is not easy for Liu Bei to have a stable territory, so let's climb the agricultural technology tree first.

Although the microscope can't be made, Zhang Xi can still make a sharp weapon against mosquitoes.

Or maybe it wasn't made by Zhang Xi, but it was there over the years.

Mosquito nets, lush grass.

Mosquito nets existed in the Spring and Autumn Period, but at this time, mosquito nets were made of silk, which could only be used by nobles, and ordinary middle and low-level officials could not afford to use them, let alone for ordinary people.

In this regard, Zhang Xi could only use the later method of using linen fibers to make mosquito nets.

Although the mosquito net made is not very good-looking, the weaving technology of this year is not good, resulting in a bit of a large eye of the mosquito net. But it's better than nothing.

And the hemp material is cheap, if it really doesn't work, you can use a straw mat, but it's a little breathable.

As for the grass that repels insects, this is also a fairly ancient method, and it was also available in the pre-Qin period, but it cannot be traced back to the source.

This method was proposed by Zhang Ji, because the ancient method is like this.

It's just that when the grass burns, the smoke is very large, and it is very choking, although it can kill snakes, insects, rats and ants, but it is also relatively toxic.

Zhang Ji also knows this, but there is no way, the toxicity is not great, how can it kill such things as snakes, insects, rats and ants.

As for being harmful to people, too. No way, if it is really according to Zhang Xi, the miasma is transmitted through these animals, then this poisonous gas is better than the miasma.

As for Zhang Xi's proposal to use wormwood, this Zhang Ji has also tried it.

It is true that there is a lot less smoke, and it doesn't feel as choking as Maocao, but wormwood is no problem with repelling mosquitoes and flies, but the effect on snakes, insects, rats and ants is very average.

In these years, the biggest enemy of Yunmengze is not mosquitoes and flies, but those poisonous insects, poisonous snakes, rats, and ants. Wait a minute.

In the end, Zhang Xi and Zhang Jiyi discussed and decided to use both.

In the soldiers' camp, it is a mosquito net with wormwood.

After all, the sergeant still has to work, in addition to taking care of the crops, he must continue to enclose the lake and cultivate fields, and he must sleep well at night.

As for the roadside fields on the outskirts of the camp, a large amount of lush grass is used to smoke snakes, insects, rats and ants to improve the living environment.

Fortunately, there are no people coming to these places for the time being, and there is no need to worry about the prevention and control of residential areas.

With Zhang Ji providing guidance, Zhang Xi is much more confident in doing things, and these things are arranged for a while, and they are quickly implemented.

At one point, Zhuge Liang wrote to Zhang Xi and asked him why he wanted a large amount of Maocao and wormwood, even to the point that it was not enough to collect local materials, so he asked him to find a way to collect them.

In this regard, Zhang Xi wrote back to Zhuge Liang and explained the truth of the matter clearly. Then Zhuge Liang had a headache.

It's all money, and it's a lot of money.

The transformation of this tidal flat into fertile land costs more money than imagined.

Moreover, Zhang Xi also said that the prevention and control of snakes, insects, rats and ants is not a one-shot deal, but needs to be carried out for a long time.

The current wormwood and grass are still enough, but after a long time, if you don't prepare, those snakes, insects, rats and ants will still make a comeback.

After all, this is Yunmengze, there are many more snakes, insects, rats and ants than people, a batch of smoke today, and maybe a new batch will move tomorrow.

Unless the entire Yunmengze is developed, and the snakes, insects, rats and ants have nowhere to live, it can be regarded as the end.

But the question is, can the snakes, insects, rats and ants in this year have nowhere to live one day?!

Two days ago, Zhuge Liang saw two mice in his back kitchen. The officials' homes can't avoid the entry and exit of these guys, and that place with dense mountains, forests and rivers will not be free of snakes, insects, rats and ants until the Year of the Monkey and the Horse Month?!

Besides, snakes, insects, rats, and ants are so heavy?!

Zhuge Liang really didn't understand this question, and wrote to ask Zhang Xi again.

And this time Zhang Xi did not answer, but directly handed over a letter from Zhang Ji to Zhuge Liang.

Zhang Ji scolded Zhuge Liang in the letter.

is different from Hua Tuo, Zhang Ji is a son of a family, he just doesn't want to be an official.

Therefore, he is qualified to scold Zhuge Liang, and as an elder, he doesn't want to write a letter to scold, even if he scolds in person, Zhuge Liang also has to bow down and listen to the training.

Of course, Zhang Ji's scolding will not be too ugly, which is a loss of identity.

After scolding, I had to tell Zhuge Liang that after such a mess, only eleven of the 1,000 soldiers who were sent to transform the fertile fields were poisoned by the miasma, and the symptoms were quite mild, and they recovered after a little treatment.

Zhuge Liang instantly realized what this meant. The four counties of Jingnan are basically the same environment, and it is inevitable that some people will suffer from miasma in summer.

This is also the reason why the four counties of Jingnan have been unfavorably developed.

Although there are some local methods to avoid the epidemic, they have never been able to grasp the essentials.

If Zhang Ji is telling the truth, then the four counties of Jingnan will be able to greatly reduce the miasma epidemic by acting in accordance with the law? !

If there is no suffering from miasma epidemic, can the four counties of Jingnan still be as sparse as they are now?!

If it's okay, if there's no if, this matter must be taken seriously.

Zhuge Liang decided that he would go to Changsha in person to see the situation on the spot.
