The matter of clearing the surrounding scouts, Riki quickly completed, not because of how powerful he was, but because the scouts who were originally cruising suddenly seemed to have disappeared.

The scouts captured by Riki were also from several other tribes, and they did not capture the headquarters of the Douwei Society.

This was expected by Yan Zheng, and it also indirectly proved that this attack was a charged blow to the headquarters of the Douwei Society.

They didn't have the greater power to launch an expedition, but they knew that if Mona received this group of wildlings, they would soon overtake them.

So they chose to give it a go and take advantage of this excellent opportunity to weaken Mona to the maximum.

This move was very bold, so that Yan Zhengdu had to take a look at it, he originally thought that the conflict would not come too soon, but now it seems that he despised these wild people.

When he studied horse theory in his previous life, in addition to practical theory, the most quintessential thing was the theory of contradiction.

The basis of the theory of contradiction is the recognition that the world is universally connected and eternally developing, and then that contradictions exist in identity and struggle.

When formulating many policies, faculty members firmly grasp the point of contradiction theory.

Yan Zheng knew that he was a little floating, and he also felt a little cynical about things.

Therefore, when he faced the Douwei Society, he ignored the theory of contradiction.

thinks that these savage tribes are not worthy of being a unified "contradictory" with themselves.

As a result, the universal connection and eternal development of the world will not change because of his idealistic ideas, they will always exist objectively.

As the other side of the contradiction, the Douwei Society and other tribes are all absorbing the beneficial conditions of Mona and developing.

Yan Zheng ignored this, which led to this underestimation of the enemy.

If he didn't have iron in hand, he didn't think the two platoons would have survived half of them.

Although as a qualified politician, he suffers from the common people and bears the infamy himself, which is the basic exercise. But this kind of avoidable casualties is better to avoid.

Thinking about this clearly, he deeply carried out self-reflection and re-faced his attitude.

After learning the hard way, he decided to recklessly make another wave of armor technology!

Let you have all kinds of tricks, Lao Tzu will be flat all the way!

He silently came to the iron-making furnace, which had been promoted to an ironworks, which had been expanded into a workshop for twenty people.

The earliest blacksmith was also given the surname of ironwood needle by Yan Zheng.

"Ironwood needle, you get some iron, make an iron piece and show me!" As soon as he came to the place, Yan Zheng shouted.

Tiemu Needle hurriedly put down the work in his hand and said respectfully: "Son of God, what are the requirements of the iron piece?" ”

Yan Zheng sat down on the side and said: "It's like a bamboo armor piece, but the iron armor piece should be lighter and thinner, and you have to save iron, so you don't have to make it as thick as a bamboo armor piece!" ”

After thinking about it carefully, Tiemu Needle immediately asked people to take out some scrap iron, melt it, and pour it into the original knife-making mold.

After cooling down a little, he used a hammer and an iron wedge to cut the piece of red iron into several pieces, and then began to pound it.

Yan Zheng frowned and looked at it, feeling that the iron wood needle already had some experience with iron.

It's just that every time before the furnace is opened, what is the matter with these people making a gesture against the stove? It's not just a trick, it's a special iron, what are they praying for affectionately?

Fortunately, these were harmless, and when a piece of iron was handed to him, he picked it up and looked at it.

It's barely suitable, but it's a little too slow to make it on a large scale.

After thinking about it for a while, I felt that it would be more reliable to make a hydraulic forging hammer, and when the time comes, a piece of armor can be done with a hammer. As long as the iron plate is suitable, it can also be directly made with a hydraulic forging hammer, as in Western Europe in the 17th century.

He sketched a simple design that did not require a hydraulic hammer to do work at a uniform speed.

In this way, the reservoir can be discarded, and at the same time, the transmission device can be made into a lever principle.

This kind of waterwheel is somewhat similar to the equipment used to mill rice in rural areas in the past, and in the era when there were no rice mills, most rural areas in the south lacked animal power and the conditions for building water-powered mills.

As a result, under the wave of collective wisdom of the working people, a very simple water-powered rice milling device was developed in the rural areas of the south, which was later improved to become a small rice milling device.

Yan Zheng had seen this kind of device when he was a child, but it had been used by the villagers to make glutinous rice cakes.

With an idea, he went to the carpentry workshop, which was a new industry, and the people who had been promoted to carpenters were already practicing how to make barrels.

They have also built a bed and a table, and although this bed is too exciting to play in a position that tends to fall apart and roll over, it already has the appearance of a bed.

As for the table, you can't use the red room with the flat ground, but you can always find a suitable place to put it in the thatched house with potholes.

Yan Zheng looked at the carpenter's tools and felt that there was still room for improvement, so he explained the general structure of the waterwheel and the function of the waterwheel.

The new carpenter didn't understand, so he could only use the leftovers to try to piece together a simple small model.

When they saw it, they immediately scratched their heads and became overwhelmed.

Yan Zheng had to simplify the waterwheel and use bamboo bone leaves, which also reduced the weight of the hydraulic forging hammer.

The principle is also very simple, that is, when the waterwheel rotates, the extended gear will bring up a lever principle forging hammer, and after disengagement, the forging hammer will be reset again.

After confirming that bamboo could be used, these crappy carpenters finally smiled.

Under Yan Zheng's command, they made the right size of leaves, and then according to this size, they began to make other leaves.

Yan Zheng also found Zhang Sanfeng, the foreman of the contractor, and asked him to take the best wall-building craftsmen to the river.

Since the flow rate of the water has always been a mystery, Yan Zheng plans to rely on the drop in water power to do the work.

The advantage of this is that no matter how much water flows in the river, the speed of the waterwheel will change within the allowable range.

After Yan Zheng made a gesture, he asked Zhang Sanfeng to excavate a space where the waterwheel could be placed in a place with a suitable height, and then use red bricks and Sanhe soil to build the entire space.

Then there is the diversion tank, which does not need to have a strong capacity to hold water, as long as the water flows down after a while in it.

The lower part is designed with a certain slope, so that after the attracted water falls from a high place, it can also ensure that it flows into the river, so that the waterwheel blades below can be driven to rotate and realize the secondary work.

If the steel production capacity goes up, even if the crucible steelmaking is realized, then this waterwheel will be much more advanced and powerful.

The reason is that more uniform work can be achieved through better transmission. Now it uses a lever principle, which lifts the hammer up and then relies on gravity to smash it down.

Four days later, the entire installation site was finally built, and the carpenters also sent the prefabricated leaves.

In order to install the waterwheel, the wooden shaft is placed first, and the bamboo is spliced with a tenon structure, and then tightly wrapped with hemp rope, and then the blade is installed.

Finally, the convex wooden gears are installed and arranged in a pattern of one every 60 degrees.

The key forging hammer is made of iron head, plus stone counterweight, depending on the workmanship effect, and the stone is increased or decreased as appropriate to achieve the purpose of weight control.

Under the full counterweight, the weight of the entire forging hammer can reach one hundred and twenty pounds (weights and measures implemented by Yan Zheng). Under the minimum counterweight, it can reach sixty catties.

This work force is far less than the European hydraulic forging hammer in the Middle Ages, but fortunately, it is more efficient than the clansmen picking up a sledgehammer and smashing it.

The only defect is the wooden shaft used, if the friction is too great if it is not greased, and the wooden shaft is easy to deform over time.

But when the sledgehammer began to rattle, the people were captivated by the spectacle.

Even the leader and the witch stood aside and watched with relish for a long time.
