The chariot was a short-lived tool of war in ancient Chinese history, and the birth of the chariot even broke the pattern of the battlefield and changed the history of military warfare, which is a powerful weapon of war.

Shen Nong spent the night sleepless, just to be able to decompose in detail the structure of the chariot he had conceived in his mind, and then draw it on the animal skin to teach Cang and the others to comprehend.

In one night's work, Shen Nong designed a total of two kinds of chariots, and in his opinion, as long as these two chariots appeared at the same time, no matter how many warriors of the Mud Eel tribe were, they would all die under the attack of the chariots.

First of all, the first type of chariot uses a double push as the forward power, the side of this chariot looks like an 'L' shape, and the body is made of wooden planks on three sides, and on these three sides of the plank, it is filled with bone cones that have been sharpened to a sharp point, as long as you charge quickly, you can penetrate any life that blocks the way in front of the chariot, which is definitely a big killer for the ordinary people of the Mud Eel tribe.

And the second type of chariot, Shen Nong designed it specifically to deal with warriors, after all, there are some obvious differences between warriors and ordinary clansmen, their combat ability is stronger, their strength is greater, and their speed is faster, the first type of chariot is afraid that even first-level fighters will be difficult to hit, let alone second-level warriors.

The forward power of this chariot is not manpower, but the Huangqiu people sitting in the chariot manually rotate the lever to drive the gear set composed of multiple gears installed inside the chariot to rotate, so as to drive the axles of the front and rear wheels of the chariot to allow the chariot to move.

On the four sides of the chariot, hard animal bones and hard animal skins should be installed to resist enemy attacks, so as to avoid the soldiers of the Mud Eel tribe from having the opportunity to harm the Huangqiu people hiding in the chariot.

Since this second type of chariot was designed by Shen Nong to deal with first-level and second-level warriors, it is naturally impossible to have no weapon system, which is the key to this chariot.

It can be deployed on the chariot and has enough lethality, it must be based on long-range weapons, Shen Nong imagined last night that each of the clansmen staying in the chariot would be equipped with a bow and arrow or a crossbow.

But these two ideas were quickly overturned by Shen Nong himself, because the production of bows and arrows is not as simple as most people imagined, even if it is barely made, whether the finished product has lethality and accuracy is also a big unknown factor.

And if you want to master archery proficiently, it will take a long time to practice archery, and it is obvious that the current Huangqiu tribe does not have enough time.

And not being able to equip the clansmen with crossbows is Shen Nong's own problem, because he doesn't know what the internal structure of the crossbow looks like at all.

After giving up the idea of bows and arrows and crossbows, Shen Nong turned his attention to the body of the tank itself, if the second type of tank is compared to a tank, the weapon system of the tank is definitely attached to the tank itself, and it is impossible to fight on the battlefield, the soldier who is in charge of driving in the tank himself takes a rifle and shoots at the surrounding enemies.

Therefore, Shen Nong conceived several high-lethality weapons that could be mounted on combat vehicles as large-scale killing weapons, but the production process of these weapons was also quite complicated and not so easy to mass-produce.

It can be seen that the difficulty of making the second type of chariot is more than several times that of the first type of chariot, which is also the reason why Shen Nong is very worried, because he is not sure whether he and others can make the second chariot before the sacrifice of the Mud Eel tribe begins, if not, there is still no hope of rescuing the bear sickle.

After telling the four people about the shape of the gears and some details of the production of the chariot, Shen Nong began to carefully teach them how to make the two chariots and how to use the gears.

As the power source of the second type of vehicle, the gear set is a very important part, and its operation determines whether the vehicle will be a weapon of war that wanders around on the battlefield to kill, or a scrap lump that stops in place.

When the sun rose to noon, the four of them relied on Shen Nong's explanation and Shen Nong's assembly structure diagram drawn on the animal skin, and finally learned roughly how to make these two chariots, which made Shen Nong secretly happy.

Because in this way, Shen Nong is not alone in making chariots, and Cang Siren can guide other Huangqiu tribesmen for him.

It's like in school, students don't know how to do a difficult problem, if every student goes to the teacher to ask, then the teacher has to explain the same topic dozens of times, and if the teacher teaches the problem in advance to four students who can quickly understand, and then let these four students teach other students who don't know yet, then the teacher's job will undoubtedly be much easier.

Shen Nong is the truth right now.

Xiong Yao was arrested, his life was in danger, and the people of the Huangqiu tribe, who lived together like a family on weekdays, were naturally anxious and anxious.

But they also know that the Huangqiu tribe is definitely not the opponent of the eel tribe, if they rush over to save people, not only may everyone not be able to save the bear sickle, but also have to be captured by the eel tribe and become sacrifices.

So at the moment, everyone knows that the only hope that can rescue Xiong Yao is Shen Nong, who brought bone shovels, stone hoes, stone pickaxes, board carts, ditches, and wooden houses to the Huangqiu tribe, there must be a way to rescue Xiong Yao.

This is the confidence of the people of the Huangqiu tribe in their own witches.

When Shen Nong finished teaching the four people in the warehouse, he walked out of the small cave to find some food to eat, he had already passed a night of supper, and he didn't sleep until noon, Shen Nong had already felt that his whole consciousness at the moment began to be in a trance, and even walking was light, as if stepping on a pile of cotton, particularly light.

"No, no, no, I have to make up for it first, otherwise I will have to die suddenly if I continue like this. Shen Nong clutched his chest and said, maybe it was because of staying up late, he felt his heart beating very fast at the moment.

The dazzling sunlight was sprinkled from the sky, and there was a white expanse in front of him, and Shen Nong's first reaction after walking out of the small cave was to quickly reach out and cover his eyes to prevent being dazzled by the strong sunlight.

And when he could gradually begin to look at the surrounding scenery, he saw that the grass not far away was filled with a mountain of wood, and the number was so large that it was difficult to count with the naked eye.

"This ...... This is too efficient, isn't it?" Shen Nong said with an incredulous expression.
