Chapter 139

PS: no one read this book? No one in the group spoke, no one in the book review spoke

Today is the first day of school. As the headmaster, Keller didn't give a lecture. I'm kidding. When did the principal teach?

Kailar wants to determine class rule naturally starts with children. Every month, there are hundreds of subjects in the monthly examination. Every chief student will be given a small cooking stove by him. This is because he wants to establish the children's mind: excellent will get the best idea, as excellent chief, they will get scholarship, Kailar's independent small stove, and more resources.

As long as the survival of the fittest learning environment is well controlled, it will not happen that the stronger the stronger and the weaker the weaker. It will only produce a virtuous circle of excellence: for scholarships, for being valued by Keller, and for more resources, they will study harder. What Keller teaches has nothing to do with their studies, but their experience in administration Do consul to cultivate, the final monthly academic examination still depends on their efforts.

So they don't worry that they are far more than other ordinary students.

It will be at least a month before Keller will be able to start teaching in the same way that he taught them before.

Maybe they will be a little unfamiliar at the beginning, but they will gradually become mature after accumulating experience, right?

The college is like a seed. As long as the rain and dew are kept, waves of towering trees will grow up and contribute to the construction of Camero.

Perhaps now this is just a small fire, but the future is bound to start a prairie fire!

Kylar sighed and sighed, which made enili on the side very strange: "what's the matter? Kay. " Enili asked with a touch of care.

"Ah Because this plan annoys helo. She's losing her temper with me How can I please her? " Keller shook his head and said, "I'm really angry this time." In the past, as long as a good wine or delicious food was given to her, helo would immediately abandon her integrity and recover. But now it seems a little difficult.

"Why does father care so much about the female wolf?" Murdred, covered in armor, said sullenly in a sullen voice. She would use this address to call Keller when there was no outsider. It was very embarrassing for him, but he couldn't correct her. Fortunately, he called that when there was no outsider.

"Care?" Keller shook his head and laughed: "no, it's called righteousness, Modred. You know, the social intercourse is built on the basis of helping each other. But after helo helped me a lot, I failed her trust. In principle, I feel very guilty, so I have to please her." Said Keller with a smile.

"But father, do you feel guilty?" Because the whole person was wrapped in tin cans, and the armor on her head made Mordred's crisp voice a little dull, and her question made Kellar laugh away.

Helo was angry because of Keller's plan to open up wasteland!

That's right, it's to open up wasteland!

Cut down the trees and build them as cities.

Such a trend must hurt the interests of the wild animals.

As one of the wild animals, helo said it was against their interests. She had to fight for it.

It's the only one. It's just for strategic purposes. Other people will not cut down trees or open up wasteland. They will go to Scotland in the future, which will crush helo one by one. But it is precisely because of this that helo ignores Keller.

I'm just sorry for helo, but it's imperative.

The city will serve as a watchtower or a defensive tower.

First of all, there is no water source near the city, which is very important. Most fortresses in both China and the West like to build a channel by the water source, or even directly on both sides of the stream through small bridges and wooden planks. The advantage of this is that it is very convenient to get water. In this world where there is lack of traffic and there is no steel pipe, it is very troublesome to get water In the age of wood materials, the so-called fire is likely to be the end of burning the city with fire.

So it's important to get water conveniently.

However, it is easy to cause landslides, mudslides and floods during flood season.

Even in ordinary days, it is very likely to be flooded by water, and defense is also a big problem. Small towns and small cities have no defense, so big cities will have a water gate.

This water gate is usually welded to death, but it is obvious that after years of erosion and man-made destruction, the so-called water gate is likely to become a flaw.

There are as many conveniences as flaws. Keller's choice is compatible.

Bronzes are very easy to preserve. As long as they are not oxidized, they can withstand the corrosion of time. (judging from the fact that the bronzes of the Qin Dynasty are still very sharp now, we can know how durable the bronzes are.) Therefore, in this era of no cement, Kailar has made up his mind to start the revolution with steel weapons. The copper that is eliminated next can not be circulated as copper money. What else can copper do? Made into utensils? Made into farm tools? Or something else?Kailar used bronze as a water pipe. Modern copper is an indispensable material with good electrical conductivity. It is mainly used for pressing shafts, cables and wires of machinery. However, in this era, copper can only be used for civilian use after losing its use as a weapon.

Water pipe!

Two huge pipes, which are held by three people, are connected from the river 20 kilometers away. They are buried in the ground two meters deep with a layer of broken stones, and then the water is directly pushed out of the ground by the force of water pressure. (imagine the pump by yourself. As long as you pour a ladle of water into the manual pump in rural areas, you can press out water. It's the same.)

After careful inspection, the city that will become a bastion in the future is also carefully examined. Below is a groundwater vein. Fifteen wells are shared by all. This water pipe will be turned into small bronze pipes to thousands of households.

And now what Keller is overseeing is what's being dug, like the Grand Canal.

Keller's personal supervision is not that he is afraid that other people will not be able to supervise him. Instead, he is ready to change his course like an engineer, because the inspiration is always coming out at any time.

These jobs are done by former Scottish farmers, most of them are about 40 years old, and their physical strength is very good
