Divine Desert Island Survival System

seaside!

Zhao Yunxiang stood by the sea, the night was pitch black, not a single ray of light could be seen on the sea surface, and the sea water was infiltrated with a tinge of terror under the dark night.

The sea is pitch-black, dark and deep, like a terrible purgatory that swallows everything.

Pick up a handful of cool sea water and wash off the sticky dirt on your body. The sea water contains a lot of saline and alkali, so you don't need to rub it deliberately to wash off the grease attached to your body.

I washed the attachments on my body a little bit. Although the sea water is very cold, it will turn into some salt grains on my body after it dries up, but it is better than sticky.

The night was dark, and the time was unknown. Back at the shelter, Zhao Yunxiang smoked his cell phone. This cell phone had already been soaked by sea water, and it still couldn't be turned on.

The mobile phone has been soaked in water for too long. At the beginning, he was soaked in water for several hours, and the mobile phone in his pocket could not be preserved at all.

"What are you doing?" Han Qianluo came over with a pot of berries, and the beautiful teacher just sat beside Zhao Yunxiang, staring at the green shelter.

The sea breeze is gentle, and the wall made of bamboo is blown by the sea breeze, and there is an unusually elegant bamboo fragrance in the air.

"I'm wondering if my phone is completely broken." Zhao Yunxiang kept pressing the power button, but the phone screen didn't light up at all.

This phone has been in the air for 10 days and looks broken.

"Don't worry about your phone..." Han Qianluo said with a blink of an eye, "Even if it's turned on, it probably won't be able to receive a signal, and there are no signal towers installed here."

Indeed, on a deserted island, even if you have a mobile phone, it is useless, because there is no signal at all.

However, besides making calls, mobile phones have many uses, shit artifact!

Moreover, the mobile phone can also tell the time!

I don't know the geometry of time here, and completely lose the concept of time.

"Have you thought about the future?" Han Qianluo asked with a small mouth.

"No..." Zhao Yunxiang responded calmly.

"No, in my impression you are a very cautious person, haven't you considered what will happen to us in the future?" Han Qianluo asked puzzled.

"No ri, go to your sister's queen?" Zhao Yunxiang complained.

"Show~!" Han Qianluo stretched out his thumb.

"I think we can do something meaningful!" Zhao Yunxiang said while staring at Han Qianluo's exquisite profile.

"Well... I'll listen to you~!" Han Qianluo nodded shyly, expressing that he could accept anything.

"Let's forge axes and swords, and make pottery?" Zhao Yunxiang said excitedly.

"??" Han Qianluo's face slowly raised a huge greeting, "Shouldn't it be doing something meaningful?"

"Is this meaningless?" Zhao Yunxiang asked.

"Hehe... I listen to you!"

In this way, the two began to toss.

It is best to fire the kiln at night, because the air at this time is very refreshing, and the high temperature of the kiln will not have much impact on the man-made kiln.

The kiln has become very strong. After all, the kiln is built with highly viscous yellow mud, especially the soil on the top layer of the kiln located in the chimney. The color of the mud is basically reddish brown, and it is a serious clay.

The formation of this kind of natural pottery clay is very complicated. As early as the Hemudu civilization period, humans knew how to use this kind of soil with few impurities and high viscosity to make pottery.

"Is it necessary to make mud first to make pottery?" Although Han Qianluo didn't understand the steps of making pottery, the TV and other things she had come into contact with could still wake up her memory.

Moreover, human beings, as advanced creatures with the most perfect intellectual development, often think for themselves,

In order to develop and perfect the production of some advanced crafts.

Move the firewood in the mud stove to the bottom of the kiln, and the burning firewood quickly ignited a lot of dry firewood. There was a little moisture inside the firewood, and there were bursts of yellow-white smoke billowing, and the kiln did not completely change. Dry, hissing under the fire.

"Zhao Yunxiang, look here!" Han Qianluo pointed to a place on the outside of the kiln, where the yellow mud that had been pasted on it had fallen off, exposing a few stones in the inner wall of the kiln.

"It's normal!" Zhao Yunxiang said, "The kiln is made of yellow mud and stones. The stones are irregular, the viscosity of the yellow mud is poor, and the gravel in the yellow mud will affect the overall kiln. "

"Is this all right?" Han Qianluo was a little worried, fearing that the kiln would collapse.

"As long as the kiln is fired, it will be fine." Zhao Yunxiang raised his eyebrows. "As early as thousands of years ago, our ancestors knew how to use flames to burn earth walls. Such walls are very strong, animal-proof and waterproof."

Yes, things after flame processing will undergo qualitative changes, such as meat will become cooked, wood with a certain oxygen content can be turned into charcoal, sand can be added to other things to become glass, etc...

The kiln is now in the open air. Zhao Yunxiang really doesn't have the energy to build a small shed to protect the kiln from the rain, so he can only do it in a few days.

However, the most urgent task is to make pottery, make some pottery bowls and jars and the like.

The kiln was successfully ignited. There is a wide ignition space under the huge kiln, and there are suspended furnace bars. After the charcoal is burned, the slag will fall along the gap of the kiln.

With enough space, the sea breeze can also blow in, which will make the flame of the kiln burn hotter and hotter.

"What temperature do you think this kiln can reach?" Han Qianluo was curious about this aspect.

After all, pottery is fired. If the temperature is not enough, then the clay cannot be fired into pottery.

However, the temperature required for firing pottery... Han Qianluo doesn't know!

However, Zhao Yunxiang knew!

"The temperature required to form pottery is more than 800 degrees, and the temperature after burning wood is about 700 degrees. The temperature reached by wood of different textures is also different." Zhao Yunxiang said briefly, "The function of the kiln is to gather temperature. , can make the temperature reach about 800~1000 degrees, the temperature depends on the size of the flame blown by the sea breeze."

You must know that a small fire will be extinguished in an instant when it is blown by the sea breeze, but a large fire will become a big fire when it is blown by the sea breeze, just like a blacksmith's bellows.

Of course, the strength of the sea breeze is not comparable to that of the bellows!

The kiln is burning, and the temperature inside is gradually rising. The kiln itself contains a lot of moisture, and now the heat is evaporating the excess moisture.

"We have to make the mud quickly!" Zhao Yunxiang frowned, and said with some concern, "It stands to reason that the mud should be made earlier, and then fired after it dries in the shade, but it takes too long to dry in the shade, so let's do it like this Give it a try."

The process and process of firing pottery are very complicated. For clay, it is required to be fine and free of impurities. The finished clay should also be dried in the shade, and it must not be fired with water, which is prone to defective products.

Of course, the craftsmanship requirements of the civilized world at this time, after all, modern people pay more attention to the integrity and style of porcelain. If you make a pottery bowl with missing edges, you will definitely not be able to sell it, but it is different on a desert island!
