Small farmers dominate the desert island

The six natives scolded immediately.

Chen Yu was not polite, and waved to the man behind him who was holding a weapon.

To execute these six people, two people pressed them to their knees on the ground, and a person stood behind them, stabbing them to death with a spear from behind.

Because pig iron is more precious now, it is not enough to make a big knife, so it can only be executed with a spear.

The six of them immediately fell into a pool of blood.

Chen Yu had no choice but to do this. If these guys were allowed to do whatever they wanted, who would follow orders in the future?This group of people must be deterred with a powerful deterrent.

After the execution of these six people, the others really trembled.

"Okay, everyone has also seen that we didn't come here to grab your things, but just wanted to form a bigger tribe with you. From now on, everyone here has books to read, everyone has skills to practice, oh no, everyone If there is meat to eat, everyone can hunt."

Chen Yu said loudly.

The prisoners looked at each other, and finally stood up slowly from the ground.

In the next one or two days, Chen Yu did ideological work for all the people in the tribe, allowing them to integrate into this big group.

Although they may have revenge for killing their father and son in front of them, but now under Chen Yu's strong leadership, they barely live together.

The patriarch of this tribe is called Ah Yi, and his name is simple and easy to understand. Chen Yu asked Ah Yi for ten foundries from the tribe, and brought them to the iron mine.

Now, beside the iron mine, there are already foundries from various tribes standing, and then Chen Yu drew a design drawing, which is the design drawing of a desert tank, and wants them to make a desert tank.

The tank designed by Chen Yu is a giant, with a length of 30 meters and a width of six meters. It can hold more than 100 people inside. It is driven by sixteen large wheels with a diameter of two meters.

Because the tank is too big, Chen Yu considered the weight issue, so not all tank bodies are made of steel, but the key parts are wrapped with iron sheets.

As for the drive, Chen Yu also used the principle of the steam engine to cast a water tank with iron and filled it with water.

After all these things were all in order, Chen Yu found charcoal in this oasis. If wood was used to burn it, the tank would run out of fuel before it ran dozens of miles. Use charcoal, something small in size and high in energy.

As for the place wrapped with iron sheets, Chen Yu considered that the sixteen wheels must be wrapped with iron sheets, and steel should be put on the iron sheets.

In this way, when the Qingyun cavalry came to find fault, he could directly drive the tank over.

Having learned the lesson from last time, Chen Yu also worked hard on the shooting holes. There are a total of forty shooting holes, five in the front, five in the back, and fifteen holes on the left and right.

However, in order to prevent others from putting lethal weapons in through the shooting holes after the arrows are used up, Chen Yu installed a cover for each shooting hole, so that the unused shooting holes can be covered.

As for the body, the front is used for impact. Chen Yu wrapped the front with a one-centimeter-thick iron sheet, and a weapon of mass destruction, the crossbow, was installed right in front of it.

Chen Yu's crossbow is a combination of 5000 years of cultural thought on the earth, and has maximized its power. The bow string is made of [-] strands of steel wire twisted, which is equivalent to the thickness of a finger.

The front bow is fixed with three giant bows, and each bow is made of tough steel.

Some people may ask, who can pull such a big bow, even if a winch is installed, it is estimated that every time one arrow is shot, the second arrow will take more than a minute to launch.

This was not difficult for Chen Yu. He had long thought of the continuous shooting performance of the crossbow, so he made the bowstring very thick so that one string could fire three arrows at the same time.

Chapter 1795 Manufacturing Earth Tanks

As long as the strength of the string is pulled to the maximum, every time it shoots an arrow, it will use the recoil of the bow to let the force-bearing device below automatically string the second string.

However, this can only be repeated three times, because after the third time, the crossbow will become extremely unstable and must be re-stringed.

As for the crossbow of the crossbow, after Chen Yu had seen the power of Qingyunwei on the Qingyun plateau, he cast the front of the whole crossbow with fine steel, and there was a ferocious forward dash on it.

Once injected into the human body, the forward lunge can hook out all the internal organs of the person.

Of course, these are all external hardware, and there are the most important core parts, that is, five gears, gears driven by steam.

The natives can't help with this thing at all, because the error of the gears must be controlled within one millimeter, otherwise, the gears will not be able to mesh with each other, and the gears may collapse if the time is too long.

This is the treasure that Chen Yu accumulated bit by bit, using the geometry, mathematics, physics, and other knowledge he learned on the earth.

From making molds in the early stage, refining molten iron, grinding gears, to installing gears, Chen Yu was in charge of everything.

His principle is to use the impact force of the steam to rotate something similar to a propeller, and then the propeller drives the small gears on both sides to rotate rapidly.

Every time the small gear rotates ten times, it can drive the middle gear to rotate one time.

The middle gear rotates ten times, which can drive the large gear to rotate one time.

Otherwise, it would be idiotic to drive two gears at once just by steam alone.

Chen Yu roughly estimated that after the steam drive is made, if it is fully activated, it should be able to travel about thirty miles a day.

Chen Yu is very dissatisfied with this speed, because it is too cumbersome to travel thirty miles a day, and others can directly find a way to fix your desert tank in place when you start it, or use other means to deal with you desert tank.

The scale of the steam engine gradually expanded. Chen Yu changed from one steam engine to two, two to four, and four to eight.

With eight steam engines, Chen Yu estimated that they could reach a speed of about [-] kilometers per hour. In this case, it is equivalent to the speed of human jogging.

It's just that in the entire desert tank, one-third of the space is used to place steam engines. The desert tank that could originally hold more than a hundred people can only hold seven or eighty people.

Chen Yu originally wanted to consider removing part of the iron sheet, but in this way, he would not have the defensive power of a tank.

Now, it is already the first month for Chen Yu to unify the oasis. After various efforts, he finally built the core steam engine of the desert tank.

The ideal is beautiful, the reality is cruel.

Chen Yu discovered the problem when he made the chicken wing steam engine for the first time.

First of all, the steam leaked, and Chen Yu managed to pull it out with a handcart, and made the cover into a screw-on type.

But in the end, the steam could not be vented, and the whole steam was blown up. If Chen Yu hadn't been there for convenience, he would have been killed on the spot.

Chen Yu closed his eyes and tried to recall the pressure cooker on the earth. It suddenly occurred to him that this kind of plateau equipment should have a vent valve. Otherwise, how would the steam in it be vented when it is not in use?

So, Chen Yu found a few pieces of wood, and used some small parts to make a high-pressure vent valve. When the density of the steam reaches a certain limit, it will spray out by itself.

Once the steam is ejected, it proves that the steam inside has reached the point where the gear can be driven.

After a day and a night of hard work, Chen Yu solved the difficulty of the steam engine explosion.

Next, the most critical moment came, using the gas from the steam engine to drive the sixteen-leaf spiral.

It is made of sixteen spoon-like leaves fixed on a six-meter-long iron rod.

At that time, the steam will drive the leaves on the top, which will make the iron rod rotate rapidly and drive the small gears on both sides.

"Master Chen, you, you are such a genius! Where did you learn this knowledge, can you teach me?" Tuba almost knelt down at Chen Yu's admiration now.

As for the other indigenous people in the tribe, they obviously felt that Chen Yu was very powerful, but they didn't understand what Chen Yu was doing.
