Scholars unparalleled

Star Seoul is currently short of manpower, especially craftsmen and the like.

Lu Chensheng was naturally delighted that a craftsman came.

"It was mainly introduced by someone."

Hearing the words on the fifth day of the lunar new year, he said on the sidelines.

The treatment in Xing Seoul is good, but the other party will not believe it before they have been here. Some people just think it is a lie.

But it's different if someone acquaintance recommends it.

The people who came from the city knew some people more or less, some were from the countryside, and they knew some good carpenters in their village, so they came to this star Seoul after being recommended.

"Well, send more people to talk about it and see if anyone they know is recommending it."

Lu Chensheng didn't care so much, anyway, if more people with crafts came, that would be the best.

Lu Chensheng flipped through the brochure, and found that many people had come recently, and the progress in some places was much faster, and his face was slightly relieved.

"The rules that were to be implemented before, have they started now?"

What Lu Chensheng said was that it is not allowed to throw rubbish anywhere, relieve oneself and so on.

It was announced a few days ago to let the people prepare, and now it has already begun to be officially implemented.

Once someone commits a crime, wages will still be deducted.

"It has already started, the current situation is good, and the people have not resisted."

Chu Wu heard the words and responded.

Lu Chensheng listened and nodded.

"The craftsmen who built the house sent someone to say that bluestone is still going to be used for the ground, and the cement paving is only going to be used on the road, and bluestone is going to be used for all the alleys."

"Is there any reason?"

"It is said that they have already arranged the drainage. There are small holes for drainage under the bluestone, which can handle a large amount of water. It will be more troublesome to use cement roads to age."

On the fifth day of the fifth day of the lunar new year, he responded with a loud voice.

Bluestone also has the benefits of bluestone and is extremely durable.

Unlike cement roads, they still face the problem of aging.

In addition, the common people still accept old-fashioned wooden houses in the construction of houses, and every arrangement of wooden houses is exquisite.

When receiving guests, there are rules about what door to open, where the table is placed, and where to receive guests.

The idea of ​​building a house out of cement bricks was also abandoned.

Lu Chensheng didn't really care much about this, because wooden houses also have the benefits of wooden houses.

If there is an earthquake or something, the wooden house has good earthquake resistance, and it is also easy to search and rescue.

The land is so big, everyone can have a small yard if they want.

As for the fire, the carpenter has a set of fire prevention methods, and there is groundwater in the valley, which provides a continuous water supply.

Lu Chensheng only needs to install more water towers.

Taking the current momentum of the water flow as an example, an Archimedes screw pump can easily bring the water to a high place and keep the water tower full of water.

Once a fire breaks out, the water in the water tower can be drawn out by using the principle of siphon to extinguish the fire.

Regarding these, Lu Chensheng had already discussed with the craftsmen before.

"Let's go with them, if you use bluestone, use bluestone."

Lu Chensheng nodded and responded directly.

The avenue is still a cement road, which is convenient for the passage of horse-drawn carriages and ensures stability.

As for the rest, don't worry so much.

For drainage, the streets are full of small holes for drainage, and the effect will indeed be better than one or two drainage channels.

"In addition, the latest peach tree seedlings have been bought."

"Did you buy the peach tree seedlings?"

When Lu Chensheng heard this, he was slightly taken aback.

Chu Wu nodded, indicating that he had indeed bought it.

Seeing this, Lu Chensheng put down the brochure, "Well, if you have something to deal with first, I will plant the peach tree seedlings first, my lord."

The trees on both sides of the valley were cut down to make furniture and houses.

Some places are quite bare at the moment.

The peach saplings were delivered, but they were just ready to be planted.

Lu Chensheng took the carriage, came to the valley and chose a place, then dug the soil and started planting peach saplings.

Seeing this, the people on the side wanted to come up to help, but were all rejected by Lu Chensheng.

When the students saw Lu Chensheng, they would run over to ask some questions.

Er Hu and the others followed Lu Chensheng for a long time, and when they saw Lu Chensheng planting peach trees, they didn't even want to help.

"Sir, we want to raise some fish in the river by the way, as well as livestock such as chickens and ducks."

Erhu felt that the water was too clear, clear to the bottom and without any fish, and a little too dead.

Lu Chensheng didn't think about raising them at first, anyway, when birds come in the future, the excreted things will bring fish eggs.

At that time, there will be fish without raising them.

But Erhu made such a request, Lu Chensheng nodded and agreed.

"Raise chickens, ducks and fish, do you want to engage in an ecological farming?"

Lu Chensheng suddenly remembered something, and glanced at Erhu and the others.

If the guess is correct, these students also want to plant some woods, the feed can be used to feed chickens and ducks, and the excretion of chickens and ducks can be used to raise fish.

And it will not pollute the water source.

"Well, I heard my husband talk about ecology and the importance of ecology, so we want to try it."

They all understood what Lu Chensheng said, and they all understood.

But it's one thing to hear it, and it's another thing to try it yourself.

"Then you can try it, sir approved."

Hearing this, Lu Chensheng nodded with a smile.

"Sir, if sheep eat grass, they will pull up the grass roots together. Why don't we think of a way to let people from other races try their best to raise sheep? Then the grassland will be eaten up little by little, and the land will become desert."

Another student took a look at the notebook and asked a little hesitantly.

Lu Chensheng was taken aback for a moment, then looked at himself as a student, probably never thought that the other party would think of this question.

If this trick is successful, it will naturally make a large area of ​​grass disappear.

"Because in the future, you can take these places for yourself. If it turns into a desert at that time, what's the use of coming here? Do you understand what the sir said?"

Lu Chensheng patted the other person's head, and then said something.

The students at the side nodded immediately after hearing the words, with a hint of understanding in their expressions.

"Also, the desertification of the land may be very simple, but it is too difficult to restore it. This kind of thing must not be messed up."

After the land becomes desertified, it will gradually erode the surrounding area, and the sand and dust will be rolled up and moved, turning into sandstorms, directly threatening the inland.

Although this trick continues, due to the decline in land fertility, nomads can only migrate and become ecological refugees, but the original fertile grasslands disappear like this, which is really a pity, and it is not good for Lu Chensheng.

Chapter 371 Thinking Like a Ghost

My own students have already thought of using ecology to attack their opponents.

This is something that Lu Chensheng had never thought of. If Lu Chensheng hadn't been sure that he could deal with the barbarians, to be honest, it would be quite good to use the method of destroying the ecology to deal with the enemy.

Even if this trick continues, the inland will be implicated, but it is much better than being sent south by these barbarians.

Once the ecology is destroyed, all the vegetation will disappear, and the land will not be fertile at all.

Naturally, the herdsmen cannot graze, but can only migrate.

When the desert is getting bigger and bigger, the opponent will think twice even if they want to invade the Han country.

Because crossing the desert is not that simple, in case of bad weather, a sandstorm can bury them all in it.

It is also normal for the nomads to die out directly when the desert spreads around.

"It's good to have such an idea, but you have to think about the consequences in everything, understand?"

Lu Chensheng glanced at the student and gave him some words of encouragement.

I just taught them about the natural environment and ecology, including what kind of huge harm will happen after the ecology is destroyed.

At this moment, the other party began to think of using this ecology as a weapon.

The students on the side nodded heavily upon hearing this.

Even though he is still a little puzzled at the moment, what Mr. said is absolutely correct.

After taking a pen to write it down in a small notebook, the student raised his head again and continued to ask.

"Mister, you also said before that species invasion is such a thing. You said that the world under our feet is very big, and some places are not suitable for breeding other species, because such species have no natural enemies here, then It will be flooded.

Students don't understand, is this species invasion so terrible?Right now, among the people in Jiang Country, Da Cang Country, and Cheng Zhou Country, there are roughly millions of people who can't afford to eat.

If cattle, sheep, or fish can be placed in such a unique place, if they can be flooded, wouldn't it be necessary to worry about food? "

Lu Chensheng's eyes widened when he heard this, and then he looked at his student.

What is going on in this student's mind?Lu Chensheng actually thought it made sense!

Use species invasion to solve the food problem?If this place is occupied, then naturally there is no problem.

At most, it is just a transportation problem on the way.

"gentlemen?"

The student looked at Lu Chensheng from the side, and called out cautiously, fearing that his idea would be miscarried again.

At the beginning, he thought it would be very useful to destroy the ecology to exterminate the nomads, but his husband refused to allow it, saying that it would cause great harm.

Now, using this method to control the desire to obtain abundant food, I don't know if my husband can agree.

Lu Chensheng took a look at his student, then nodded, "There is no place for you to experiment right now, but if there is a new place in the future, how about letting you try it?"

Lu Chensheng patted the other person's head, thinking that this kid was a bit of a genius.

Hearing this, the student's face was full of surprise, and he nodded excitedly.

Lu Chensheng shook his head. If the invasion of species is not curbed, it will also lead to the destruction of the ecological balance.

For example, if there are no natural enemies for rabbits in a place, the wild rabbits in this place can be flooded, and then they will continue to eat the vegetation, causing all the vegetation to be eaten up, and then the hares will naturally be extinct.

But Lu Chensheng felt that if he intervened one or two as a human being, and periodically hunted and killed them and brought them to the dining table, he thought it would be possible to maintain the ecological balance.

If this move is successful, then breeding will be much easier in the future.

However, this idea is a bit too long ago. I am afraid that such a place can only be found after going to sea.

The students on the side asked a few more questions, then saluted respectfully, then turned and left.

"What did you mean by what you just said?"

Bai Yi had already come to the side as early as just now. Hearing what Lu Chensheng and his students were saying, she was taken aback for a while, completely unaware of what they were talking about.

The rest of the students on the side listened with gusto and took notes.

At this moment, Bai Yihu felt that what he had learned was not as good as these students.

"It's just talking about nature, such as earthquakes, tsunamis, volcanoes, and ecological circulatory systems."

Nature and the like are actually a subject that these students are quite interested in, and the other is Tianxue.

It's just that Lu Chensheng really doesn't know a lot about Tianxue, so he can only pick out some things he knows, and talk to his students as if they were extracurricular knowledge.

Bai Yi listened in a daze, "The student just said that if those nomads were allowed to herd sheep in large numbers and eat the turf, they would make themselves extinct. Is this true?"
