The audience couldn't imagine that Chen Xu was really building a house!

Ten minutes had passed, and he had planted four sticks more than one meter long around the flat ground and formed a regular rectangle three meters long and two meters wide.

Seeing that Lena hadn't come back yet, he had to find a few vines nearby, and fixed one of the two-meter-long sticks to the top of the other two two-meter-long sticks with a figure-eight knot.

Subsequently, Chen Xu used tree thorns to pierce two deep holes in the front and back of the four pillars, and finally carefully took them and inserted them into the soil holes.

After tying the other two sticks to the crossbar, the rough skeleton of the whole house came out.

"2333, how does it look like a single parallel bar!"

"Master Xu, please start your gymnastics performance!"

"The one-meter-high horizontal bars on both sides should be the wall, and the two-meter-high horizontal bars in the middle should be the roof beams, right?"

"Creative mode!"

And just when Chen Xu was about to build a fence, there was a sparse "rustle" sound in the trees in the north.

It turned out that Lena came back with a bunch of bushes and vines, "Do you think it works?"

"Very well, it's just the right time to come back!"

Chen Xu took the shrub branch, immediately pulled out two of them, and fixed them with vines at the top.

And while he was making it, Lena took out a few yellow fruits with a little dark spots from her pocket with a little excitement, "In the process of looking for branches, I found some wild apricots, and now is the time to ripen, I have tasted them, and they are a little sour!"

"But it contains a lot of sugar, protein, and calcium and other nutrients, which is good for energy!"

"Thank you!"

Chen Xu thanked him, because the apricots in the deep mountains did not have pesticides, he just wiped them slightly and threw them directly into his mouth.

Suddenly, a stream of sweet and sour juice spread in his mouth with the fruity aroma unique to apricots, as if he had recovered from the fatigue of rushing and cutting down trees before.

"This is the skeleton of the house, it looks very sturdy, but the height difference between the ridge and the side wall is a bit big, almost 2:1, so the slope of the roof also increases, which is not conducive to building leaves on the top, right?"

Lena admired the speed with which he built the skeleton of the house, but she couldn't help but have some doubts in her heart.

"It is necessary to have a large slope, I have calculated, it is about 45 degrees, because there are many heavy rains in Argentina in summer, if the slope of the roof is not large, it cannot be drained in time, and it is easy to accumulate rain and leak in the end. ”

"And I didn't say I'm going to put leaves on it, I'm going to tie leaves!"

As he spoke, Chen Xu had already tied several shrub branches with vines.

Next, it was time for Lena and the audience to blow their minds.

He took these fixed triangular shrub branches and hung them directly on the ridge of the roof like building blocks.

In this way, with the vine at the top fastened, the two shrub branches naturally hang on the ridge of the roof, and the remaining two sides are placed on the beams of the side wall.

Under everyone's surprised gaze, Chen Xu took vines and bolted these branches and beams tightly, and the prototype of the roof of a tree house had already come out!

"I can't believe it's made without any tools!"

Lina glared at the same time, she also held the vine and joined Chen Xu's "knotting" team.

In the Army, she also learned the relevant knotting method, because it is one of the compulsory courses for wilderness rescue and climbing skills in complex terrain.

Ten minutes later, the skeleton of the entire roof was built.

Chen Xu took another shrub branch, found a large broad leaf from the surroundings, whether fresh or yellow, and then pierced them flat on the branch like a meat skewer.

Two minutes later, a string of branches covered with leaves was displayed under the camera of the live broadcast room.

"It's amazing, I thought Xu Ye saved so many leaves to wipe his ass!"

"What are you going to do, masturbation?"

"This should be tied to the roof to keep out the rain, right?"

……

As said in the barrage, Chen Xu held the branch full of leaves, gently put it on the lower end of the roof, and then used vines to wrap it several times from both sides to fix it on the skeleton of the shrub that had been tied before.

When Lena saw this scene, she didn't know how to describe the surprise in her heart.

No wonder this kid is not afraid that the slope will be large and the leaves will fall, it turns out that he actually thought of such a powerful fixing method!

In this way, it is difficult to blow down the roof, let alone heavy rain, even if it is heavy rain and strong winds.

For a forty-five day survival period, this is definitely a top-tier shelter!

But some viewers also raised doubts, like these leaves should rot in a few days after being exposed to the wind and sun.

Then won't this roof be built in vain?

To this, Chen Xu replied: "The environment with the fastest leaf decay is the tropical rainforest, while central Argentina has a subtropical climate and belongs to the mountain forest environment, and the leaves need at least a month to decay. ”

"And the premise of this time is that the leaves fall to the ground, which is greatly affected by the decomposition of microorganisms, and if they are hung in mid-air like me, their rotting time will be multiplied!"

Chen was right. ”

Lena, a biologist, knew he was right.

Subsequently, she also looked for broad-leaved leaves around, learned Chen Xu's method, and helped him wear them together.

With the help of one more person, the construction of the roof was significantly faster.

An hour later, the two of them had tied a total of two dozen shrub branches covered with leaves.

In an instant, a simple treehouse was built!

Chen Xu glanced up at the sun and muttered: "Sure enough, the cooperation between the two of them is much faster than I expected, I originally thought that it would be dark at this level, but now it seems that we can still find some food, and by the way, observe the surrounding terrain!"

It took the two of them to find this campsite at about three o'clock, and this treehouse took about three hours to build.

That is, it is almost six o'clock in the afternoon in Argentina.

According to the usual time, it will indeed be dark at this time, but now it is the long summer of the Southern Hemisphere, and the daytime time is much longer than the night, at least seven or eight o'clock, before it enters the night.

"It's also important to make a fire, this is a mountainous area, the temperature will drop very much at night, just with the little clothes we have now, if we don't make a fire to keep warm, we will catch a cold!"

Lena reminded.

Chen Xu nodded, and then asked, "How about your technique of drilling wood to make fire?"

She thought for a moment: "It's okay." ”

"Well, I'll go out and find some food, and by the way, I'll survey the surrounding terrain!"

After speaking, Chen Xu picked up the thorn that had been sharpened before, turned around and went into the jungle.
