The reason why Wu vomited was because... I can't help it, it's too unpalatable. The continuous babbling sound only had a tendency to stop after Wu poured a large bowl of cold white boiling.

The curious tribesmen, although they saw Wu's face turned green after eating salt, there were still a few people who wanted to try it. Everyone thought that maybe it was just that Wu didn't like the taste, after all, the juice grilled fish and the broth cooked in a stone pot made by Wang Tian were delicious.

"Hmmm! It must be like this! After some self-hypnosis, a few more people reached out. But they were immediately mercilessly slapped with the burning stick in Wang Tian's hand.

Although the tribe already has salt, it can't be wasted like this. "This salt is not eaten like this, I will cook food for everyone tonight, use salt for everyone to taste, and everyone will know." Wang Tian could only explain like this.

Then Wang Tian dismissed everyone and asked everyone to continue the work of making salt, he called the second brother of King Kong to pose a triangular shape of the ancient horse with a branch on the ground, and explained to the second brother in detail how to make it and precautions, the second brother took the little Fu horse and left with the people of the logging team and a few strong female primitives.

Wang Tian is planning to make the ancient defensive weapon horse rejection pile, before the wall is made, in fact, with the protection of the horse rejection pile, it can prevent most of the beasts from approaching the tribe.

Wang Tian planned to place the horse in front of the place where the wall was to be built, so that after the wall was built, the tribe would have a two-tier defense system. Before the wall is built, it can also play a role in protecting the safety of the tribe, at least allowing time to react in the event of an attack.

Later, he also planned to fence off the right side of the tribe's cave all the way to the brick factory with a horse. The tribe is strategically located, with a river in front of it and a mountain in the back, so you only need to block it to the left and right.

With the continuous production of mud bricks. In a later period of time, it is necessary to start firing lime and red bricks, and this firing work will last for 2~3 days or even longer. This necessitates leaving people to spend the night outside the cave. Security is something that has to be considered.

The production process of pottery also needs to be improved, and there is also the problem of keeping people to keep vigils, and the boiling of table salt can also be carried out at night on the observation deck after the horse is refused.

The reason why Wang Tian didn't think of it before was because what he was thinking about at that time was the wall, and he automatically ignored this simple but very effective defensive weapon.

The so-called horse rejection pile is a kind of triangular fence invented by the ancient Chinese people, which is mainly used to block the charge of the enemy's cavalry on the battlefield, as well as an important military baggage to prevent collision on the periphery of important military strongholds.

Generally, it is arranged at the city gate, near the military camp, and on the important passes, which is inexpensive, can be carried and reused, and the materials used to make it are available everywhere, so it is deeply loved by the ancient Chinese army.

China is the first country in the world to use horse rejection piles, which originated from a weapon called staghorn wood, which is said to have appeared as early as the Xia, Shang and Zhou periods.

Antlers are made by sharpening a tree shaped like antlers and burying it in the ground, and it is generally used once and is difficult to move. By the Tang Dynasty, a lightweight type of repulsor that was easy to move appeared.

It is made of three guns with tips at both ends tied together, so that they can be easily carried around when they need to be moved. This kind of rejection horse is also equipped with a chain, which can connect several groups of rejection horses at the same time.

As a kind of obstacle weapon, it is widely used in arranging formations and camping. The Warring States Mojia called the rejection of the horse "sharp iron", "Mozi" has a special article "Prepare the Moth Fu" on the "sharp iron" tactics: the moth Fu, the enemy soldiers moth ants like a surging also, at this time, along the way cloth five elements of the sharp iron, the line spacing is three feet, the root is buried three feet, the sharp cone is five feet long, can block the enemy's advance.

In the middle of the Warring States period, the rejection of horses developed into iron spears as the head, that is, the rejection of horse guns, with solid wood as a fixed support, and then fixed 6 to 10 iron spears on the frame, all over the enemy's road so that its cavalry could not gallop.

What Wang Tian needed now was a sturdy, immovable fixed horse-repelling post, and there were no iron spear heads, but there were many bamboos.

Therefore, he divided the shape of the horse made by the second brother into three layers, not only with a row of sharpened bamboo sticks stuck straight at the top, but also three rows diagonally on the side facing the enemy, and a circle of thorns and rattan in the gap in the front.

It is impossible to push the horses from the front with long logs tied to the bottom of each section of the horses more than three meters in length, and then strung together into a whole with tough rattans. In the middle, there is a section of mobile horses that can be moved for the entry and exit of the tribesmen.

After the second brother left for a while, Wang Tian saw Xiao Fuma dragging a bundle of firewood back to the tribe, and everyone in the tribe followed behind with three pieces of wood for each of them.

In the past few days, a lot of wood has been stored, but because it is a freshly cut tree, it contains a lot of water, and it takes a lot of manpower and material resources to carry it. Therefore, it has never been brought back to the tribe, but has been placed in the same place to wait for dryness before coming back to retrieve it.

Every time the second brother of King Kong came back from work, he just brought some firewood for the fire.

After the materials were in place, the simple structure of the rejection horse naturally did not need Wang Tian to worry about, and the second brother took people to start the production afterwards.

According to Wang Tian's design, the total height of the rejected horse is two meters (the top bamboo gun), and the maximum width is also two meters (the length of the log at the bottom). The width of the right triangle of the body is one meter, and the height is 1 meter5. Two sticks are tied horizontally on the beveled side.

The trees in the primeval jungle are tall and straight, and trees with a height of 10 meters can be seen everywhere, and the carbonization and binding of the main body of the horse rejection pile are quickly completed, but it is extremely difficult to intercept and sharpen the bamboo spear. Anyone who has been involved in carpentry knows that the tough and resilient bamboo is only suitable for interception with a hacksaw, and when the axe is chopped up, it will either break the bamboo tube or be injured by the rebounding axe. (Unless there is an Oriental knife from the movie)

It is almost impossible to cut out a beveled spear head with a bulky axe, and it is also unrealistic to use a small saw on Wang Tian's saber to cut out a 70-meter-long rejection of horse. In the end, it was all made of wood.

The metal axe in the hands of the second brother of King Kong now plays a huge role in the tribe, without it, it will be extremely difficult to make the rejection of horses, kiln firing and firing red bricks, although it can also be completed, but the time of this production will be counted in years.

Wang Tian is more eager to get metal materials than ever, and at this moment, he is extremely nostalgic for the people who will break the copper and iron in the future. Advanced production tools represent advanced productivity. Time is running out, but "he is young" always feels that there is not enough time.
