The scope of this fence was decided after discussion by Lin Shu and Yesen. The tribe will soon build a more spacious brick and tile house, and sufficient open space must be reserved.

Lin Shu planned to build a house according to the layout of the field grid, leave a wide road in the middle, and then pave the road with small stones.

I feel like a beautiful life is right in front of me!

Lin Shu was thinking about the future situation, while watching the scene of building a large fence in front of her, and smiled.

Ye Sen saw Lin Shu smiling while looking at her, he followed her gaze and glanced at the other people who took off their upper skin jacket because of the heat, revealing large areas of muscles. He suddenly felt a little unhappy in his heart.

He went up to say hello to Lin Shu, and stood cleverly on Lin Shu's side, allowing her gaze to turn naturally in another direction.

"You are making such a fast progress. You have hit so many wooden stakes so quickly!" Lin Shu exclaimed.

"Well, it will take about ten days to complete it." Ye Sen replied lightly.

"Look at this kind of vine," Lin Shu took out a vine she found when she collected it and carefully handed it to Ye Sen, "Be careful."

The vine was covered with sharp thorns, which made people unable to start for a while. Even if you pick it up, you could only barely pinch the tip of the thorn.

When Lin Shu went out to collect today, she found this thorny vine, which was the one she stepped on when she escaped from the wild boar.

In an instant, the pain of being stabbed in the soles of her feet seemed to appear again. Lin Shu wanted to walk around from afar, but then she thought about it and cut off another piece and brought it back.

"We can plant this vines under the wooden stakes after the fence wall is completed. When they grow around the fence, they can strengthen the fence and act as a precaution."

Lin Shu blinked at Yesen cunningly, "The entire fence will be thorned by then. Not to mention breaking in, others will not even dare to touch it."

Yesen was silent with the vine covered with thick and hard thorns, and nodded with some difficulty: "This method... is very good."

"Oh by the way, we can also dig some traps outside the tribe."

Lin Shu was afraid that Yesen would not know what a trap was, so she explained, "It was just digging a big hole and then covering the surface with branches and leaves. People or beasts who didn't know wouldn't come out if they fell in."

"This method is good. I will take people to dig after the fence is completed." Ye Sen expressed his approval.

Lin Shu was affirmed and popularized all the trap arrangements and key points she saw in modern times with Yesen.

"We can insert spikes into the trap, and the fallen enemy or beast will die on the spot. You can also set up open bows and arrows on the roadside. Once the enemy triggers the mechanism that restrains the bowstring, they will be killed immediately by an arrow..."

As she said, the trap area was full of dangers and dangers, and I am afraid that even a mosquito could not fly over.

Ye Sen imagined that kind of scene and couldn't help asking, "Are these... all the beast gods taught you?"

Lin Shu was stunned for a moment, and smiled a little stiffly: "Yes. Did you do it too much?"

"I just think you have these clever ways to live a good life even by yourself, and it's amazing."

"Fortunately you are from our Sen tribe. If it is an enemy, it would be bad." Ye Sen said with a smile.

Five days later, the first batch of bricks were completely air-dried. Lin Shu and Lao He and his group carefully placed the bricks into the kiln and filled the four kilns.

The bricks are much thicker than ordinary pottery. Lin Shu and Lao He took turns adding firewood to the kiln to maintain the high temperature inside the kiln.

The fire burned for a whole day and a night before it gradually began to go out. It was not until the next afternoon that the furnace, which had dissipated, opened again.

The success rate of bricks is much higher than that of pottery. Lin Shu took out the bricks and saw that the burned bricks were solid and hard, with a square body grayish-white.

Xiao Shitou picked up the brick and slammed it: "It's still quite heavy, but it seems that it's not as heavy as the stone."

Lin Shu knocked on the bricks with her hand, and the bricks made a familiar and crisp sound: "The bricks have been successful. Next, we will continue to burn the second batch of bricks and tiles."

"Oh by the way, the wood ash left by burning pottery before were all added with water and made into mud to accumulate." Lin Shu instructed before leaving, "I'm of great use."

A week later, the bricks and tiles made by Lin Shu and the others piled into a hill on the edge of the kiln.

Everyone passing by would stop in front of this hill for a while, questioning each other:

"What is this thing Lin Shu asked Lao He and the others to burn? Is the new pottery?"

"It doesn't seem useful to see these! So many are thrown on the ground like this, they should be waste pottery."

"Hey, what do you know? I heard from my son that this is a brick, which is of great use!"

"Really? What's the use?"

"This...I don't know this yet..."

...

Lin Shu guessed that there were enough bricks, and the stucco plaster left by burning bricks had accumulated half of the room. She waved her hand and began the last step in preparing for the building: burning cement.

What she burns is the simplest and most primitive cement.

Put the dried stucco plaster into the kiln and calcined it into an off-white slurry, and then mix it with sand and soil and water in a ratio of one to three, and the simple version of cement is obtained.

Yesen heard that Lin Shu was about to start building a house, so he also brought people to help.

As early as Yesen and his team were about to start building fences, Lin Shu drew a plan for building a house in her heart.

She used a wooden stick to draw the location where the wall was to be built on the ground. She looked at the strong men who were bringing help with the construction in front of her, and smiled and ordered: "Excavation!"

Foundations are the basics of building a house. First dig a foundation and then build a wall so that the house will be stable.

The onlookers then realized that they were building a house. When they heard that Lin Shu wanted to build a new house for all the people, they all helped enthusiastically.

No, this is not called help, this is called building a house for yourself!

Dig the foundation, build walls, cut down trees and build beams, and lay tiles on the roof...

Everyone was skeptical at first, not knowing how Lin Shu would use these bricks to build the house.It just does things completely according to Lin Shu's command.

After the brick walls were built higher and higher, they gradually understood what was going on. This is the same as building a stone house!

The materials required for the stone house are difficult to collect, and the construction process is time-consuming and laborious.However, Lin Shu's brick house materials can be mass-produced by themselves, and the bricks are also lightweight.

And the most wonderful thing is that these bricks are square, and the mud called "cement" made by Lin Shu is glued, so there is no need to consider the problem of the bricks rolling down during the construction process. The stones are not so easy to fiddle with!
