Zong Shu was very satisfied when he captured all the 200 Jin soldiers who came to encircle and suppress them without missing a single one.

Jin Bing was not afraid of hundreds of more soldiers, because Li Shaoyan and the Xi people already had experience in the three-dimensional combat method in the mountains and forests.

In this battle, only one arrow was used.

What would be the result if the Xi people fired thousands of arrows in the air?

Thinking of this, Zong Shu immediately told Li Shaoyan to expand the air corridor as soon as possible to form a T-shape, ring, or rectangle that can be connected to each other.

For example, if you add a few more circular air corridors, as long as you lure the enemy here, thousands of arrows will be fired in the air, there will be no blind spots, and the golden people will have no way to avoid them.

The air corridor should be distinguished between the enemy luring area and the enemy annihilation area.

Combined with the traps and obstacles on the ground, the three-dimensional combat network becomes a meat grinder for the Jin people, and Khanwula Mountain becomes a sad place for the Jin people.

The captured Jin men were put on duty the next day, and their task was to dig for coal and iron ore.

As a result, the Xi tribe freed up many people to participate in the repair and expansion of the mountain three-dimensional combat network.

Just when the Xi people were in high spirits and waiting for the Jin people to attack, everyone suddenly discovered: The Jin people didn't move at all!

This should not be the style and characteristics of Jin people!

Unknowingly, two hundred Jin men were killed, including one general who had returned from the battlefield against Liao.

The Jin people must have known about it, and they also sent two small teams of personnel to investigate.

But there was no sign of troop mobilization after that.

Is this the case for the Golden Man?

Was there a reversal on the Liao battlefield?

Xiao Xiaoxiao and the "Great Song Volunteer Army" beat the Jin army until they couldn't find Bei?

Has Wanyanping left Linhuang Mansion and gone to Daqingshan?

So, is it possible to sneak into the north city of Linhuang Mansion and kill the captured Emperor Tianzuo?

No matter what happens to the Jin people, you have taken advantage, so just wait and see what happens, and stay the same to cope with all changes.

Zong Shu calmed down and began to discuss techniques with Mihua and Mi Gulu.

Zong Shu’s understanding of the Xi people started by building cars.

Xi Ren is good at building bikes, and he is also good at walking on mountains. Mountain bikes are amazing.

Car-making is a specialty of the Xi people, and they used this to trade with other tribes. When they were forced to go into the mountains, they took all the equipment and materials for car-making with them.

Zong Shu's eyes widened when he saw the cars in Xi's car workshop.

The proportions of this car are really out of proportion.

The wheels are higher than the body!

After Mi Hua explained it, Zong Shu finally understood that the Xi people could really figure it out!

The roads in the mountains and forests are narrow, so the car body is small. When encountering difficult sections of road, the wheels are large and not easy to get stuck.

When encountering small ditches and bumps, we passed them in no time.

Mi Gulu said proudly that the most difficult thing about the Xi people's cars, which is also difficult for outsiders to imitate, is the wheel production technology.

The wheels made by the Xi people are better than other tribes, including the Song Dynasty, and their service life is two to three times longer than ordinary wheels.

The main reason is that Xiren can achieve the most perfect combination of the three parts of the wheel: hub, spokes and teeth.

Take the hub part as an example. When selecting materials, you must remember the sunny side and the negative side.

The wood grain on the sunny side is denser and the wood is hard, and the wood grain on the back side is sparse and the wood is soft. Therefore, the back side needs to be baked with fire to make the wood become as hard as the sunny side.

Even if the hub is worn out, the wood will not shrink and cause the part wrapped on it to bulge.

Mi Gulu said that they had tried to put iron rings on the wheels before, but the effect was not good and the iron rings would always fall off.

If iron rings can be put on, the wheels will not wear out.

Putting iron sheets on the wheels is like putting iron shoes on the horses.

Zong Shu looked at their iron hoops, measured the wheels, and said, "This is easy to handle. Take these and go to Cao Yishou."

Mi Gulu, Li Shaoyan, Wu Fei, Niu Gao and others also followed.

Arriving at Cao Yishou's blacksmith shop, Zong Shu asked him to put the iron ring in the stove to heat it.

At the same time, he asked several Xi people to boil a basin of water. After the water boiled, Zong Shu asked him to pass the wooden wheel in the water.

When the iron ring was burning red, Zong Shu asked Cao Yishou and several Xi people to put the iron ring on the wheel.

Suddenly, the ice on the surface of the wheel turned into water vapor and rose.

Cao and Xiren held pliers in one hand and a hammer in the other to completely fit the iron ring to the wheel.

After fitting, immediately pour water on the iron ring.

Mi Gulu took the iron-wrapped wheel and rolled it on the ground, praising it again and again.

He had people wrap the wheel in the blacksmith shop many times, but every time, no matter how hard he beat it, there was still some looseness.

This iron-covered wheel is so perfect that the iron and wooden wheels fit together perfectly.

Mihua and several other Xiren also came over to take a look. They were also experts at building cars. They could tell by touching it that the iron sheet and the wooden wheel had formed one body.

How to do it? Mi Gulu took the wheel and studied it carefully.

Among those who followed, only Li Shaoyan and Cao Yishou vaguely understood the reason.

Zong Shu coughed lightly, and Cao Zongshen immediately moved a chair over. He knew this was a signal that the young master was going to speak and teach.

"Everyone, do you know the physical phenomenon of thermal expansion and contraction?"

Thermal expansion and contraction?

Li Shaoyan knew that Zong Shu's style was generally "heuristic" teaching, rather than cramming and reciting teaching methods.

Thermal expansion and contraction? Yes, that must be the case!

"Grandmaster," Li Shaoyan is used to calling him this way on such occasions: "I know that if you like someone, you will be enthusiastic, and if you don't like someone, you will be listless..."

"Stop it, stop it," Zong Shu quickly stopped the chatterbox: "What you are talking about is a physiological phenomenon. It has nothing to do with today's topic."

Wu Fei took a step forward and said: "Master, you must be using this phenomenon to inspire us, asking us to maintain a mentality of not being arrogant in victory and not discouraged in defeat. When it is hot, don't expand. When it is cold, don't shrink..."

Zong Shu found it refreshing to hear Wu Fei's analysis and interpretation, which was unique!

"Yes, Wu is not, what he said is absolutely true! That's what I mean. If you win the battle, you will raise your tail to the sky. If you lose the battle, the tree will fall and the hozen will scatter. Therefore, we must see the essence through the phenomenon, and see through the essence

Look at the spirit!”

Zong Shu praised Wu Fei, but saw that Li Shaoyan was a little lonely, so he changed his tone: "Of course, what Li Shaoyan said is not completely unreasonable. Everything in the world is universally connected."

Zong Shu stood up from his chair, took the iron-wrapped wheel and said:

"Put the wooden wheel through water and let it freeze. This is called cold shrinkage. It also prevents the wood from being scorched by the red iron."

"Let the iron sheet burn and let it reach a high temperature. This is called thermal expansion. At this time, you can put it on the wooden wheel, pound it firmly and stick it tightly, and then pour water on it to cool it down."

"In this way, the iron sheet is tightly wrapped on the wooden wheel. This is the relationship between the foreskin and thermal expansion and contraction."

After Zong Shu explained, both Mihua and Mi Gulu understood. They sometimes noticed these phenomena in their lives, but they didn't summarize them.

Nor have they applied these phenomena to real life.

As expected of a divine messenger! When Mi Gulu looked at Zong Shu, he felt that he was not only a divine messenger, but also a spiritual messenger sent by his ancestor Mi Xin to help Xi Ren overcome difficulties!

Cao Zongshen looked at the shock of the Xi clan members and was a little disapproving: Isn't this just child's play for the young master?

Look at these Xi people, they really have never seen the world. If they saw ice cubes burning wood and glass making rainbows, I don’t know how shocked they would be.

Cao Zongshen had long forgotten the scene when he watched Zong Shu and Lin Lingsu fight in the school field. At that time, he was not much better than these mockers.

"Grandmaster, Jinren, there is something going on!"
Chapter completed!
