Take Baidu to the Wilderness

After the mud is made, it can be used to make bricks.To make bricks, you need a brick mold. Sprinkle a thin layer of plant ash or sand in the mold, then pick up the mud balls and put them in the mold, compact them flat, and then pour the mold to separate the bricks from it. After drying, you can put them in the mold. Burn it in a brick kiln.

As Yan Tu's voice fell, Tori quickly assigned tasks. Some of the tribe were responsible for digging sand in the stream, and some of them went to the forest to cut a few trees to make brick models. Try to cut trees in densely populated areas of the forest. This will not only cause less damage, but also give other trees nutrients, sunlight and rain.The remaining people were divided into two groups, one group worked in brick kilns, and the other group was responsible for digging clay.Because the children showed great enthusiasm for digging when making pottery before, and the efficiency was not low, so this time all the children were assigned to the group of digging clay, and there were not many adults, only a few .

After the work was assigned, everyone dispersed. They were also listening when Yan Tu spoke just now, so naturally they knew exactly what they should do at this time.The only one who was assigned to be a brick kiln was still standing there dumbfounded.Compared with them, although the person in charge of making the brick mold is also confused and doesn't know what the mold should look like, but no matter what he says, he is better than them, and he knows that the first step is to go to the forest to cut trees.

It was Tori who guessed that the mold was made of wood, and he was relieved when he found that Yan Tu's expression was the same.But even if he could guess, he couldn't think of what a brick kiln should look like and how to build it?

I have no choice but to continue to bother Yan Tu.Fortunately, when Yan Tu saw the people who stayed behind, he immediately understood the reason, and explained: "A brick kiln is actually similar to a cave, as long as there are additional vent holes, a place for firewood to burn, and a place for brick embryos to be placed." The location is almost enough. The main thing is that the place needs to be large, and more bricks can be put in at one time, because we have little time after all.”

As soon as Yan Tu said, the clansmen understood, they just didn't understand, and with a little inspiration, they could do better than many people.

After Yan Tu finished speaking, they left confidently and walked to the other side of the mountain where no one dug caves to live in.

After finishing all this, there is nothing to do for the time being. He found an open space to sit down, pulled out the system panel and started Baidu Great Wall Structure, intending to draw a blueprint according to the city wall and use it to build the wall.

Because there is no iron here, if there is a door on the wall, you can only use a wooden door, which is easy to be breached as a weak point. At that time, no matter how tall and strong the wall is, it will be useless, and natural conditions do not allow it. There is only one shallow door in the tribe. Shallow streams, although the water level will skyrocket during the rainy season, cannot be used as moats.This stream is the source of drinking water for the tribe. In order to ensure the drinking water of the tribe, not only can it not be placed outside the wall as a moat to block the enemy, but it must be enclosed in the wall for protection.

There are no gates and no moats, but there can be no drawbridges.

Different from the suspension bridge outside the ancient city wall, the suspension bridge here is only for the convenience of the clansmen entering and exiting the tribe. The design can be changed slightly, changing the bridge to a basket.Install a fixed pulley on the top of the wall, tie two or more ropes, one end of the rope is on the pulley, and the other end is tied to the hanging basket.People stand in the hanging basket and can enter and exit the enclosure wall by turning the fixed pulley with the help of others.In this way, as long as the hanging basket is put away, it is impossible for outsiders to break into the tribe without permission, even wild animals.

Stairs should be built inside the wall to facilitate the clansmen to climb up the wall.The top of the wall is the same as the city wall, there must be enough space for people to walk and fight on it.In addition to the stabilizer pulley as a labor-saving device, a high platform must be built on the wall, which can be climbed at any time to observe the enemy's situation.In fact, it is better to build a tall tower, but considering the current technology, Yan Tu silently crossed out the watchtower and changed it to a watchtower.

There should also be guardrails on the wall to prevent the clansmen from accidentally falling, and at the same time, they can also cover attacks during combat, and even have certain defensive capabilities.In order to save materials and improve performance, the guardrails should be uneven and have holes, so that it is convenient to observe the enemy's situation from the holes, and to attack them unexpectedly from the holes.

It seems that there is nothing else to add besides these.Yan Tu sat on the ground and thought about it for a while, but he still couldn't think of anything new, so he went back to the cave to find a large animal skin, walked around to the kitchen when he came out, and picked a piece from the ashes left over from cooking last night. Charcoal out the door.

Spread the animal skins on the ground, Yan Tu squeezed charcoal and began to paint and draw on it. When Tori came, he saw a clear and clear diagram of the wall structure.

Yan Tu has studied fine arts, and painting is as natural to him as eating and drinking. Although the structural drawing is different from painting, there are always similarities, so it is not difficult for Yan Tu to paint.

After drawing the structural diagram, Yantu also carefully marked various dimensions such as length and width, because no one here knows the unit of measurement, so Yantu did not use meters or centimeters, but directly compared with the actual object. The height of the wall is four Tori is tall (Tori is about two meters tall), the width is one Tori wide and so on.

This is really easier to understand. At least after reading it, Tori immediately understood the method of building walls.

After drawing the blueprint, Yantu stood up, stretched his muscles, and moved his hands and feet, and he was in the mood to pay attention to others.

The clansmen responsible for digging sand have dug a lot of sand.In the nearby open space, the sand was piled high like a hill, and there were already three such hills.So they stopped for a while, and began to focus on picking out the sundries in the sand and throwing them aside.

The diggers are still digging. Compared with the adults, the children are almost crazy about playing. They are very satisfied with the work assigned to them today.

Because the clay used to make bricks requires deep underground soil, so the children dug and dug, and finally they couldn't hook it with short hands, so they could only stand by the pit and worry.I don’t know which ghost spirit came up with the bad idea in the end. Taking the lead while the adults around were not paying attention, they jumped into the pit secretly, dug the soil and put it in a tree bag, and when the bag was full, let them guard by the pit My little friends pulled the vine tied to the tree bag and slowly lifted the clay up.

Someone started this matter, and the children followed suit one after another. There were so many people jumping into the pit, it was hard not to be discovered.When Yan Tu noticed them, a group of children who were digging in the pit and their bodies were covered with mud, just like mud monkeys, were caught by the Tathagata's Wuzhi Mountain.

After coming out of the pit, in order to prevent them from jumping down secretly again, the adults decided to let them step on the mud. They didn't ask for anything else, as long as they stepped on the mud firmly.

So a group of children with excess energy found a new way to vent, jumping and jumping on the mud, and making up stories one by one, very happy.

Seeing their happy faces, the adults just noticed and didn’t say anything. Anyway, they were still doing their work, so it was okay to let them play without delaying things. Who didn’t have such a busy childhood to sneak in and have fun?

The behavior of the children reminded the adults of their carefree childhood, smiles appeared on their faces involuntarily, and they even worked harder.

Yan Tu smiled and looked away, looking elsewhere.

The people who built the brick kilns were still working hard, obviously not yet successful, but the clansmen who went to cut trees in the forest just came back.

Seeing the big tree on their shoulders, Yan Tu hurried over to help.

"What should I do next?" The clansman walking at the front unloaded the tree from his shoulders, put it on the ground, and asked Yan Tu while wiping his sweat.

Yan Tu didn't care if he didn't help, and replied when he heard the other party's question: "Cut off the four sides first." Yan Tu pointed to the trunk and motioned for the other party to cut the cylindrical trunk into a square column: "Then divide the trunk into roughly Take two palm-length pieces of wood, then cut them in half, and dig a flat hole in the middle." Yan Tu stretched out his hand and gestured where the tree hole should be dug, how big and small, how deep and how shallow : "That's about it."

The people of the tribe began to operate with stone knives as promised, and Yan Tu specially asked them to make four larger brick molds. The bricks made by such brick molds will be larger than other bricks and can be used to lay foundations.

Although stones can be used to lay the foundation, it is a pity that there are too many stones around, but the shape does not meet the requirements at all.All of them are in strange shapes, and they have to be polished hard before they can be used. With this time, it is better to make more green bricks.

After talking about what the brick mold looks like, Yan Tu also had a rest, and pulled out the system panel Baidu again.

Before a strong enemy comes, in addition to strengthening the defense, the attack cannot be dropped.Now there is no copper and iron, weapons such as swords cannot be made, but others are still possible: such as bows and arrows, such as crossbows, such as short spears for throwing and catapults, etc.

Considering the practicality, Yan Tu first Baidu is the catapult, because it has the most lethality.Think about it, there are wild beasts densely packed outside the wall, and they are scrambling to hit the wall to attack, hideous and terrifying.But we put a few catapults on the top of the wall, and threw boulders down one after another, not to mention driving them away, killing some of them, so as to prevent each other from stepping on each other and climbing up the wall. It is always possible to defend the tribe.

The manufacture of catapults is simple and very simple, but it is also a bit difficult to say that it is actually the principle of leverage.Because Tori could understand the drawings of the fence, Yan Tu found another way to communicate with them. After all, some things, especially complicated instruments, cannot be explained clearly by just describing them in words.

Yan Tu returned to the cave with a few pieces of animal skins and two pieces of charcoal, and carefully compared the structural diagrams found on Baidu to start drawing.

In addition to the catapult, Yan Tu also drew the fixed pulleys that were previously imagined to control the lifting of the hanging basket. After marking the size, Yan Tu continued to Baidu other things, intending to add more weapons for the tribe.
