Wilderness: After the college entrance examination, I got the strongest survival system

After pouring out the clay in the basket, Li Yingjie looked at Lin Xiaoying's wrist and asked:
"Does your wrist still hurt?"

Lin Xiaoying moved a bit, then shook her head, "Fortunately, there is no problem if you don't need too much effort."

Li Yingjie smiled, pointed at the clay and asked, "Have you ever seen bricks?"

Lin Xiaoying was silent for a moment, "... seen it!"

Asking herself such mentally handicapped questions, Lin Xiaoying wished she could find a brick to pat him on the head. If she was a real city person, she would know nothing, so she would ask questions like whether she had seen a brick.

Li Yingjie twitched the corner of his mouth proudly, and then said: "It's easy to handle if you have seen bricks. You can knead all this clay into the shape of bricks, and it will be useful in a while!"

With that said, he walked to the front of the shelter and dug the pit where the kindling was buried.

When the fire is burning hot, burn the firewood for a while, and then cover it with the ashes of the previously burned plants. The firewood inside can burn all day. They burn it in the morning and come back at night, and there is still an open fire inside.

This is what Lin Xiaoying learned when she saw the ancient human's method of preserving fire when she was studying the history of ancient humans.

This method is a good solution to the problem of drilling wood to make fire. They don't need to maintain the fire for a day, they just need to keep some slow-burning charcoal in this pit, and ignite the dry grass when they use it.

Li Yingjie dug up the fire, lit the fire, and said to Lin Xiaoying:

"I will come back as soon as possible. If there is a wild beast coming, you can hide behind the fire and wait for me. If you have to escape in other directions, try to leave a direction for me. Of course, depending on the situation in the past few days, if there is a wild beast The danger is not great."

After Li Yingjie finished speaking, he carried his twig basket on his back, and trotted towards the river.

According to his own speed, it will take about an hour and a half to go back and forth. It's still early in the day, and it won't be dark at all for two or three hours.

Li Yingjie trotted over, filled a basket of clay, and quickly walked back to the shelter.

Because he didn't have a watch, he didn't know how much time it took, but after returning to the shelter, Li Yingjie was slightly relieved to see Lin Xiaoying still kneading brick embryos.

I was a little suspicious, and felt that Lin Xiaoying might be in danger along the way.

But in the wilderness, they really need to be vigilant at all times. They still don't know anything about this small island. If there are really powerful beasts here, it will be very dangerous.

Back in front of the shelter, Li Yingjie poured out the clay, looked at the brick embryo that Lin Xiaoying kneaded, and said amusedly, "Have you ever seen bricks of different sizes?"

Just look at the dozens of brick embryos placed on the ground, each of which is different in size. The longest length is nearly [-] centimeters, and the smallest length is only about [-] centimeters.

"How does this work?"

Lin Xiaoying glanced at him angrily.

"Do you know that it's very difficult, you can't make it the same size at all!"

With the clay mud in one hand, two coats of mud were rubbed on her face, which looked a little funny.

Li Yingjie squatted down, stretched out his hand to grab a ball of clay, and tossed it back and forth several times in his hand, and soon a brick embryo with a length of [-] centimeters and a width of about [-] centimeters was made.

Putting the brick embryo aside, Li Yingjie grabbed another ball of clay, tossed it back and forth in his hand, and made another one.

The size of the two brick embryos is basically the same.

"Is it difficult? I think it's very simple. Can you see if you can squeeze it into the same size?"

Li Yingjie put the two brick embryos in front of Lin Xiaoying and asked.

Lin Xiaoying raised her eyebrows, "Hey, you and your sister raised the bar!"

As he spoke, he laughed loudly, raised his hand, and wiped the clay on Li Yingjie's face.
