There are many stones on the seashore, and some of these stones have been washed up from the sea by the waves.

Some people may ask, are the waves that strong?

Of course, the power of the waves is very strong, and they never stop, they can be stronger under the drive of strong winds, and violent natural disasters can also increase the power of the waves tens of thousands of times!

Like, the tsunami!

Zhao Yunxiang pulled the stone on the beach, this is a very huge stone, about more than 40 catties, the color of the stone is gray and white, the surface is smooth, slightly potholes.

"Quartzite!" Zhao Yunxiang looked at the stone in his hand in surprise, "It is said that if the quartz content in this stone is greater than 90%, then it will contain mica, feldspar, magnetite and other minerals. ”

Quartzite, like jade and obsidian, is a hard, hard-textured stone that was a necessity in the Neolithic period, but it took luck to make a sharp stone knife or axe.

Because the hardness of the stone is very high, relative, and fragile, just like the glass we are familiar with, if you want to make a knife out of glass, it is not to see what shape you want, but what shape the glass will form after it is broken.

Zhao Yunxiang found a plaque with a slight shape, some sharp stones at both ends, and a wooden stick.

First, the stick is thrown against the stone, and a crack is made, and the crack appears in the center of one end of the stick.

Zhao Yunxiang stuffed the prepared stone into the gap of the wooden stick, because one side of the stone is irregular cone, and the thickness of the front end is very thin, probably less than one centimeter, but as it extends, the stone thickens at 60 degrees, and by smashing the stone hard, it can easily open the crack of the wooden stick.

“OK！”

Zhao Yunxiang successfully stuck the stone chips in the gap, and then tied the stone chips firmly with vine ropes.

[Congratulations to the host for successfully crafting an inferior stone axe, handcrafting proficiency +15]

Inferior stone axes

Production techniques, bundling, combination

Weight: 4 kg

Robustness: 25

Hammer Power +7

Bulk density of bluestone axe: 2.73kg/m³

Bluestone axe hardness: 145

Bending strength of bluestone axe: 87MPa

Compressive strength of bluestone axe: 86MPa

The inferior stone axe is made of bluestone, the hardness of this stone is okay, the density is moderate in the stone, no fracture layer is found, as long as it is used carefully, it should not break off.

But the quartz stone on the beach, this stone has been exposed to the wind and sun, and there are several cracks in the middle, which is the life gate of quartz, as long as you knock it properly, I believe it can be broken quickly.

The length of the wooden handle of the stone axe is about 1.4 meters, which Zhao Yunxiang deliberately made so long, because using the principle of leverage, it almost does not take much effort to greatly increase the strength of swinging the stone axe.

Of course, the anti-shock force will also be greatly bounced back from the wooden handle.

The production of stone tools is divided into beating and grinding, and the sharpness of the beaten stone tools far exceeds that of the polished ones.

The former depends on luck, and the latter relies on kung fu and experience!

"Ding ding~!"

"Dangdang~!"

After a few strokes, the quartzite was smashed open, and a few pieces of stone flakes of a few centimeters splashed out, and with just a few smashes, Zhao Yunxiang got what he wanted.

Stones for cutting meat!

Pick up the triangular piece of quartzite fragment on the ground, the fracture of this stone is shell-shaped, fan-shaped, the edge is thin, wavy, and the sharpness is impeccable!

Picking up the small stone, Zhao Yunxiang began to cut the meat, sure enough, this kind of stone is the best to cut the meat, although it is slow to cut because of its small size, but it is very sharp, and the carcass of the guinea pig is quickly decomposed.

The meat is cut into long strips and placed on one washed leaf, and the bones that stick to the minced meat and green tendons are placed on another leaf.

The rest of the intestines, the guinea pig head that had been cleaned of the meat, and the inedible scraps were dug and buried by Zhao Yunxiang, and then a wooden stick was inserted to mark it.

These things are still useful, but not now, burying them can effectively prevent meat from spoiling.

The advantage of disposing of corpses by the sea is that you don't have to worry about the smell of blood attracting flies, because the blood is carried into the sea by the waves before it can spread into the air.

Unfortunately, there are no big fish like sharks as far as the eye can see, but there is a group of little sardins who love the tiny minced meat and gore that swim in the water.

"The sea, the most mysterious place in the world, with the largest number of species. Zhao Yunxiang took a deep look at the sea, and then returned to the coconut tree with the meat.

Under the coconut tree, Simba had finished eating the guinea pig offal that Zhao Yunxiang had prepared for him, and the big lion was bowing his head and drinking water next to the puddle.

The depth of the mud pit increased again, and the water inside also seeped out continuously, and after a long period of clarification, the water was no longer muddy, but still had a smell of earth.

Zhao Yunxiang looked at the puddle and remembered that Sim Kat ate guinea pig offal, and there was snow foam dripping from its mouth, "It seems that it is necessary to dig another puddle...... No, it's a well!"

Digging wells is a must, and what Zhao Yunxiang wants to do is find a spring or dig up groundwater, and then build a huge reservoir.

Because with water, you can have everything, such as domestic water and industrial water!

Zhao Yunxiang didn't find Han Xuening this time, this Nizi is always idle, she seems to have gotten all the wood that can be carried around, and these woods are excellent building materials.

"Han Xuening, you just finished drinking the medicine, it's best to sleep and sweat. Zhao Yunxiang also collected many huge leaves, and as long as these leaves are piled up, they are the ideal quilt.

"You're still busy, how can I rest?" Han Xuening dropped more than a dozen wooden sticks again, I have to say that this girl's strength is really great, these wooden sticks make Zhao Yunxiang difficult to carry.

The strength of primitive people is great, and it is really practiced!

"Don't be busy collecting wood yet, go and clean this skin, and I'll use it later." Zhao Yunxiang threw the guinea pig's fur to Han Xuening, and the animal skin needs to be exposed to the sun before it can become harder and can be stored for a long time.

"Okay!" Han Xuening took the animal skin and went to clean it up.

Zhao Yunxiang added some firewood to the fire again, and checked the blackened stones in the fire, the temperature of these stones was okay, and the meat of the guinea pig could be fried on it.

The heat conductivity of the stone is very poor, and the clam meat that was just placed on it is already 4 ripe, turn it over again and continue frying.

This kind of fried meat should be quite delicious, but now I can only cook it and make tools at the same time.

The fur of the guinea pig is not large, and if he can, Zhao Yunxiang would prefer to use it to make shoes, but first he has to let the fur of the guinea pig be shaped and dried.

A few pieces of wood and a few vines make a triangle that can be used to shape the guinea pig's fur.

"After washing, what's the use of you doing this?" Han Xuening looked at the strange triangle.

"Take the shaped guinea pig fur, when the fur is exposed to water, it will inevitably shrink and wrinkle, if the fur is fully unfolded and tied in this frame, it will become a very good fur, you can make a few pairs of shoes for me!" Zhao Yunxiang nodded affirmatively.

"Shoes?!" Han Xuening asked suspiciously, "What are shoes?"

"It's a bit troublesome to make shoes, and the original production process is even more cumbersome, requiring needlework, fur, and ......," Zhao Yunxiang looked at the woods, "When the evening comes, I will go to the woods to collect those precious things, because they are an important ingredient that makes up the soles of shoes!"
