When the audience heard this, they suddenly realized. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Of course, before building the stone wall, Chen Xu first found a dead branch as a broom to clean up all the garbage in the ground in the cave.

"There is no smell of animal feces in the hole, which is a good sign, indicating that there are no animals living here, and yes, the hole here is very open, and it really does not give the animals a sense of security. ”

Then, he began to collect the wild grass and dead leaves around him and spread them on the ground, making a thick layer.

After finishing everything, Chen Xu picked up a granite of the right size with sharp edges from the ground as a hand axe, and then found a few small trees the thickness of a baby's arm in the nearby jungle.

"This is cork oak, a kind of evergreen broad-leaved forest distributed in the low altitude of Shennongjia, its wood is resistant to water and moisture, will not rot easily, is an important wooden building material, and most importantly, its cork is very thick, very tough, we can use its bark directly as a rope!"

As he spoke, he picked up the stone and slammed the tip of the tree against the trunk.

After about a dozen strokes, the opening was already two or three centimeters deep, and he immediately pressed the trunk of the tree, and with a fierce break, the whole small tree was broken.

Chen Xu tore off the bark directly along the opening, the bark was white, very thick, but very soft, he pulled it hard a few times in front of the camera, "You see, the toughness of this bark is comparable to ordinary nylon rope!"

After more than forty minutes, he cut down a total of eight small trees.

Then find a few short branches, combine them in pairs, first tie them into an "H" shape with bark, and after stabilization, then add two more horizontal bars up and down the middle horizontal bar.

"When kidnapping, you must pay attention to the narrow top and wide bottom, in a trapezoidal shape, so that it can be stable and reliable!"

Explaining the kung fu to the audience, Chen Xu made a total of four such shelves.

Then he began to look for large pieces of stones, along one side of the hole, and began to pile them up.

The thickness is the width of the bottom of the wooden frame, and when it is about the height of the lowest horizontal bar, Chen Xu inserts the three shelves in a vertical arrangement in turn.

Because the four shelves were not easily toppled because they were supported by stones, he continued to build stones on them.

In this way, some stones press against the bars, which will make the shelves more stable.

In turn, the bars of these shelves hold the sides of the stone wall in place, and the vertical tree trunks hold the front of the stone wall in place, like steel bars, making the stone wall stable and strong.

Chen Xu pushed the stone wall from top to bottom, left and right, nodded, and said with a smile: "Yes, this is already very stable, and it is difficult for ordinary animals to collapse." ”

He only built the stone wall to chest height, keeping a certain distance from the top and side of the hole.

"Don't forget that these two pieces should be half a meter empty when building the stone wall, one as an exit, one as a vent, and the second point is particularly important, after all, it is easy to produce a large amount of carbon monoxide when making a fire in the cave, and if it is not treated well, the concentration is too high, and it is easy to cause poisoning. ”

After listening to it, many viewers played a barrage:

"666, Xu Ye is always full of details!"

"Sure enough, when the entrance of the cave is blocked, the sense of security is immediately reflected, and you don't have to worry about beasts and wind and rain anymore!"

"Little brick mover, Master Xu, you can come to work at my construction site tomorrow!"

Chen Xu shook his head and smiled, and then touched his stomach: "The campsite has been set up, but I haven't eaten for most of the day, and now I'm very hungry, I have to go out to find some food in the afternoon, but before that, I have to make a shoe out of these hay first!"

In the afternoon, he finally found hay nearby, and then spent more than half an hour weaving two pairs of straw sandals.

The technique is the same as the vine shoes that I knitted on the island last time, but the hay is softer than the vines, so the straw shoes are more comfortable, thicker, and very easy to step on.

Putting on his shoes, Chen Xu took the previous bone stick, found a sharp basalt block from the ground, and simply polished it with obsidian.

Obsidian is harder than basalt, and it is still easy to carve grooves.

Then, taking the rest of the bark and following the grooves, he tied the stone blade cross to the hollow of the large bone, and made a simple stone axe to make it more lethal, and then began to go up the mountain in search of food.

"Shennongjia is humid and hot, this environment is easy to breed all kinds of poisonous insects, poisonous snakes, some people even call Shennongjia 'Chinese snake valley', in addition to sea snakes, basically all kinds of vipers, pit vipers, cobras, soldering iron heads and other poisonous snakes can be found. ”

"Therefore, when we pass by these dense bushes, we must be very careful, try not to scratch these branches, we must be very careful, in case we are bitten or stung, there is no medicine, it may cause poisoning and death!"

Half an hour later, when Chen Xu passed by a bush, he carefully walked through it while explaining to the audience.

And just as he finished explaining, suddenly, on the branch in front of him, two snakes with black bodies and white heads, one up and down, were looking at it "with a tiger's eye".

It is the first time for many viewers to see such a pure white snake head, which looks like a warm jade, with two jet-black eyes, which looks a little cute.

"Wow, this snake is so cute!"

"Hey, hey, Xuye's food is here!"

"Bald Head: Forehead...... How I feel like I've found something amazing!"

Seeing this snake, Chen Xu's eyes widened and he grinned, "We are so lucky, these are two extremely rare albino vipers! You must know that normal vipers are marked, or dark, so that they can better hide in the branches and dead grass, which is convenient for hunting and avoiding natural enemies." ”

"But the two in front of me, obviously suffered from genetic mutations, before coming, I checked the information, Shennongjia is one of the places with the most albino animals in the world, all kinds of albino bears, albino monkeys, albino deer have been found here, as for why Shennongjia has the ability to make animals albino, this is still a mystery. ”

"Generally, snakes act alone, they gather together, it is likely to be in estrus, unfortunately, albinos are a rare species protected by the state, these two vipers we can't kill, vipers belong to the highly venomous snake species, when we pass, we must be careful!"

Looking at these two albino vipers, Chen Xu shook his head, sighed, and had to "endure the pain" and let it go.

If it weren't for the protection of national laws, two vipers would be enough for him to eat a delicious meal.

"666, Xu Ye, is this a disturbance to the vipers?"

"Mother Viper: Oh, I'm so shy!"

"Alas, Xu Ye not only has to survive at the limit of Shennongjia, but also receives various legal restrictions, it is really difficult to live!"

Chen Xu smiled and walked safely through the dense jungle, at this time, there were several "rustling" movements in the wild grass in front of him.
