There are some drawbacks that tend to cause harm later.

Qian Rujun is most worried about what they have not learned is the drainage of some key water sources, especially to the students of Xuetang Island, if they are explained to do this part of the project, whether they understand it or not, they must find a way to tell more people the principle.

It's better to say now than to come back and blame them when something happens in the future.

And the maintenance after that must be done by them, if they don't do the maintenance, they would rather have the land bought back at the expense of Jinmai City than let them use it.

But they believe that people are more concerned about the longer the water can be used for a longer period of time than they are.

There shouldn't be a problem with the maintenance work, but if you let the rich people do such things in the future, maybe the maintenance work will not be done well.

Qian Rujun suddenly discovered that if you want to do a good job, it is not so simple.

If you don't want to care about the environment, Qian Rujun doesn't need to care about what others do.

Qian Rujun can live her own life behind closed doors, and others dare not affect her life.

But what Qian Rujun did was the first time since the beginning of the world.

And in the eyes of others, such things often look at the pros and cons to decide whether they want to do it.

But the person who has a favorable heart can not necessarily see how everything is done.

Because a person with a ghost in his heart will always think that others don't want him to study, so all learning comes secretly.

There will always be bias, and when there is bias in the heart, it is difficult to do things completely.

Qian Rujun's big project in Dahan, naturally there is no way, like in Sunshine City and Pear-shaped Island, he did it so casually, threw things to a few people, and left so relieved.

Because Sunshine City and Pear Island are not inhabited by the people of the Han Dynasty, Qian Rujun's concern for them, because there is no contact with each other, there is no blood relationship, and there is no relationship of common interests in the future, so Qian Rujun does not pay much attention to the future life of these people, and even suppresses these people.

And Qian Rujun knows that most of the students on Xuetang Island are good people and have not been oppressed too much, so they do not have the psychology of oppressing others, and they are still a little measured towards people.

They don't mistreat these people.

Those who don't abuse their subordinates to work for them are good people in Dahan.

In order to lead these people to carry out the project, Qian Rujun must choose ten locations and walk back and forth, and this back and forth often has to run these ten locations in one day.

So Qian Rujun is actually very busy, and time flies very quickly when he is busy.

Time flies, summer goes to winter, and half a year has passed in the busy, half a year, in the past, it was very slow for Qian Rujun, because although she was busy every day, the busy things made her feel very boring.

Maybe doing the same thing day after day will make her feel bored.

But she has been doing the same thing for half a year, but while doing the same thing.

But what was in front of her began to change in her eyes.

At first, it was a mess, a bunch of people talking to the students of the school island, and then a mess of the construction site began to appear, and then it was rectified by the students of the school island and became neat.

When order was put in order, the earth began to change.

Man began to transform the land.

Gradually, the fields spread out with the development of the water, and at the same time, new farming techniques were taught.

In half a year, for most places, most of the production work was stopped, the fields were handed over to women or children, and the men carried the tools to the construction site.

It stands to reason that the first thing they should be dealing with is the lack of food production, and local officials will also be unhappy with this.

Even the tax on food has been lowered.

But these tax money Rujun has helped them make up for it.

After paying the taxes, when these people were digging the reservoir, they found that although the work was very hard and even their lives could be dangerous, in most cases, the people who led the work of the reservoir allowed them to avoid the danger.

Their lives are only in danger if they are particularly careless.

Speaking of which, they usually encounter more dangers than accidents when digging into the water.

If they really encounter danger to their lives or become disabled when they are digging a reservoir, they can really only blame themselves, not the people who lead them.

The man who led the excavation had thought of all possible things for them, and had told them when to be careful and what not to do.

The people who have accidents are often the people who are not careless about doing things, and the most satisfying thing for these people who dig the water is that they usually even if they farm, they still have no meal, but during the time they are digging the water tank, they find that they give their family fields to their families to cultivate, and under the special distribution of farm tools by the people digging the water tank, they can actually cultivate the results similar to when they planted.

And all the food is available to their family, and the food he eats himself belongs to the digging workshop, which will cook for them to eat, so after the family loses a share of food expenses, their lives have become better.

And after this water is dug up, according to the agreement, there is their share.

This field is definitely a very good field to cultivate after irrigation, thinking of the future, many people look at the water in their eyes, and they are even more happy in their hearts.

Half a year, hurrying and spending a lot of manpower, the first water tank designed by the students of Xuetang Island was finally completed, and on this day, the students of Xuetang Island gathered around Qian Rujun, introduced the water tank to Qian Rujun, and told them how to distribute the fields irrigated by the water tank later.

"Shuizhen has just been completed, and this field, which has not been cultivated, is very fertile, so we let them grow vegetables, because it is already winter, and the cabbage is cold-resistant and can be cultivated, and the vegetables can grow quickly.

Only cabbage is planted this winter, and they are also able to live a good life

Cabbage, according to the princess, can be pickled, and it is not a problem to put the cabbage for a year or two after pickling.

The best time to eat it is to leave it for 21 days and then eat it slowly.

But why can't the princess eat it for twenty-one days?

I've tasted that, and within 21 days, it tastes pretty good. ”

The students of Xuetang Island have more or less experimented with what the people have announced.

Qian Rujun said that if they eat it at a certain time, although it is poisonous, the toxicity will not be strong enough to make them die immediately, so they tested it.

"Although the taste is good, but it is harmful to the body, salt is put in the dish, in six hours to twenty-one days, in fact, the toxicity is getting higher and higher, don't think that salt is not poisonous, salt and many things will produce chemical toxins, often let you eat without feeling.

And then when you overdose, you get poisoned, so you can't eat leftovers all the time.

Leftovers with salt will be most toxic after six hours. But those dishes are just as delicious. ”

Although the students of Xuetang Island have learned a lot of things, they don't know much about such simple truths, and perhaps these truths are too commonplace, so Qian Rujun did not tell the students of Xuetang Island.

Qian Rujun naturally wouldn't tell him the principle of these things, if they wanted to know, every time Qian Rujun told the principle, they could only do the experiment themselves and get the results of the experiment.

It's a pity that there are many experimental tools in this era, but Qian Rujun has seen the practical tools that the students of Xuetang Island often lack tools, and they will find a way to make a more suitable tool by themselves.

But Qian Rujun knows that the machines needed for real precision analysis are not those that can be made by hand.

Perhaps at some stage, their machines will be upgraded to more sophisticated machines, and future research will be more and more in-depth.

Qian Rujun sometimes thinks to himself, they have twenty times the time of others, maybe they can use so much time, and they don't need to re-learn, keep accumulating, keep growing, maybe have twenty times the time of others, the wisdom they can accumulate, maybe surpass others a hundred times, because they not only have twenty times the time, but also the result of continuous spiritual water injection, improve their wisdom, and their wisdom is continuous, there is no need to repeat learning, their health can always be kept in a good state, and the recovery of spirit is not a problem in the space at all。

It's even better than when they're out there, and if he hadn't slept at night, he would have saved that time.

Qian Rujun has reason to believe that if it weren't for Qian Rujun's-stirring stick, maybe their development would be better than now, after all, these times, if they had grown up enough to be in their twenties in the outside world, the reason why they were still able to maintain a young mentality now was because they didn't get along with outsiders during their research time, and they didn't need to manage those troublesome things.

As long as they can communicate with people in the same situation as them, there are no too complicated things, and because they are also under the management of Qian Rujun, these people actually don't have too much cunning psychology.

In other words, with the slightest interpersonal communication, they can concentrate on their own business.

At most, they were sent out by Qian Rujun to do things, and spending half a year in charge of spreading the motor like this time was actually a waste of time for them.

Qian Rujun suddenly thought that maybe she should let them open schools in various places.

Qian Rujun can take people back at any time, but if this is the case, Qian Rujun will become a transporter to serve everyone.

In this way, Qian Rujun is not the master, but has become a driver.

But it is indeed a good thing to open up people's wisdom. It's also the easiest thing to do.

Qian Rujun knows that in this era, the Han people read very little, because there are few readers, so their thinking is limited.

Most people are thinking about what others have communicated. There is no way to form your own ideas.

At this time, people who read books have important conditions for disseminating the knowledge of others, because they understand the propaganda, although at this time, the imperial court will not announce some propaganda to the people, but there are some important things, they will still publicize through some literature.

And let these people read to others to know.

Those who read it to others often control the interpretation of the text.

Because they can hide things that the local people don't know, and these things may have enough benefits for them.

At this time, for their own interests, they thought that whether the people knew or not, in fact, had no impact on the major affairs of the imperial court.

Knowledge is power, and it is in the case of the Han Dynasty that it can be best reflected.

A person who can read, even if he goes to the people, can receive enough money for food by teaching the people some basic concepts, or helping others to read, arithmetic, and write.

It doesn't need to be as hard as the average farmer.

If it was in Qian Rujun, it was almost unimaginable in that era, because there were very few people who didn't know words in Qian Rujun's era, and people who didn't know words were often out of touch with the world.

Although they can also watch some film and television programs, the knowledge that film and television programs can bring them is still relatively small, so many people who have not read books especially like some radio programs.

Because all the people that the radio program can bring to them are people with good words, they can hear the news from it, get some entertainment, and even do their own things while listening.

Qian Rujun found that she had a lot to do around the people she was familiar with, but she had already dug a big hole and let the students of Xuetang Island jump down, if she opened another school and taught to read and write, it might be more troublesome, in fact, Jinmaicheng and Chang'an Women's School have expanded the publicity of reading, these people can actually replace the work that Xuetang Island students have to do, and it is good to let these people out.

It's just that there are still relatively few people who can get orders from the Central Water Tower District or Jinmai City, and start to act after hearing their orders.

Because only those who receive their scholarships for study have a few years, they must listen to Jinmaicheng.

Qian Rujun thinks that these people may not be willing to do such a thing, even if they are willing to do this, there may not be many people who go out to teach.

Qian Rujun thought about it, maybe he had to let Jinmai City and the Central Water Tower District collect some people, let Qian Rujun brainwash these people, teach them enough methods to educate others, and let them teach people, especially to be teachers.

As for all the teachers, Qian Rujun decided to give them the best life, as well as the best food, to make their brains smarter, of course, they had to follow the instructions of the Central Water Tower District and Xuetang Island, and go to the places where the people's wisdom was not opened, that is, they had to sell themselves to these two places, and they could not be set free until they behaved well.
