Divine Desert Island Survival System

　　 Outside the shelter!

　　 Zhao Yunxiang took Han Qianluo to a place on the west side of the bamboo forest!

　　 This is a rock wall, and the stone texture on the rock wall is basalt!

　　 "Are you going to use these stones to make grinding discs?" Han Qianluo squatted on the ground, watching the huge stones falling from the rock wall.

　　 These stones look very hard, unlike the granite around the shelter, because those stones have been eroded by rain and sea water for a long time, and clear fracture layers have appeared, just like steps.

　　 And, the huge basalt in front of me is a complete whole, this somewhat square stone is less than 300 kilograms.

　　 "Yes, you may not believe it!" Zhao Yunxiang sighed slightly, squinted up to the sky, and then sighed.

　　 Han Qianluo twitched when he saw it, knowing that Old Zhao was going to remember again, and whenever Zhao Yunxiang showed such an expression, he wanted to remember!

　　 "Tell me your story..." Han Qian raised his brows and pointed to the dense forest where the monkey was. "I'm going to make wine in a while, lychee wine."

"My grandfather is a stonemason. Because his family is very poor, he often makes grinding discs for others. After all, he has to support my father and brothers 3 and an aunt." Zhao Yunxiang said, "Because of making grinding discs for people for a long time, I got pneumonia. , Eventually led to lung fibrosis, and died of illness within a few years of retirement, and was tortured for a long time..."

　　 "..." Han Qianluo looked at the hammer and the chisel that had just been made with the valve, and wanted to persuade, "Otherwise, let's stop making grinding discs, it will be bad for your health."

　　 "It's okay, I have a shield!" Zhao Yunxiang knew that a lot of stone powder would appear in the process of excavating the stone. Because there is no air gun to blow, you can only blow with your mouth. In this process, it is inevitable that the stone powder will be inhaled into your lungs.

　　 Of course, it is not one or two times that you will get western pneumonia. This is an occupational disease for many years.

　　 I made two small chisels, using two valves. The valve is like a horn. It is a good chisel.

　　 After simple heat treatment, forging, quenching, the hardness of the small chisel is very high.

　　 However, it is basalt after all. The hardness of this kind of stone is no joke. Zhao Yunxiang knows that two valves alone can't handle it.

　　 Therefore, I can only transport the stone back!

　　 Although the stone is huge, but using the principle of leverage, it did not take long to roll back to the shelter!

　　 The work must be carried out in the shelter, the ghost knows whether the group of sharks will suddenly attack!

　　 Although I know that those guys are afraid of the sun and don't like to hang out during the day, even at night, they usually don't cross the coral reef, but there are exceptions. If those guys come, they will kill the twins in minutes.

　　 "Ding Ding...Dangdang..." The huge basalt rock was vulnerable under Zhao Yunxiang's hammer and chisel, and a large number of stone chips were flying in the sky.

　　 However, the valve made of steel material lost its hardness not long after being excavated.

　　 After all, it is such an excavation method like a hard stone, so naturally it cannot be held!

　　 "Han Qianluo, go and burn this red, and then hit it to the tip with a hammer, and the quenching must be done!" Zhao Yunxiang handed to Han Qianluo a valve whose hardness disappeared and the chisel tip turned into a round head.

　　 She knows how to deal with it, and she can do it very well in a short while!

"Okay, I see!" Han Qianluo immediately came to the front of the mud stove and opened the vent behind the mud stove. When the vent opened, the flame instantly became bigger, but this time the sea breeze was not big and the flame was not like before. That's so exuberant.

　　 Therefore, heat treatment takes a while...

　　 Zhao Yunxiang made two chisels, probably because of the texture and the degree of quenching. The hardness of the two chisels is completely different. After drilling on the basalt for a long time this time, there is no problem with the chisels.

　　 "Sure enough, it's still not professional enough!" Zhao Yunxiang digs the back side of the grinding disc on one side, and then continues to process the other side.

　　The grinding pan was invented by our ancestors in order to crush grains through gully stones. This kind of thing is very suitable for making pancakes.

　　 In the beginning, the ancients opened a pit in the stone, then threw the harvested grain into the pit and smashed it with the stone. This method often resulted in a lot of stone particles.

　　 After all, this kind of impact behavior can easily cause a little cracking of stones that are not hard, and it is normal for impurity stones to appear.

　　 And, stones are not easy to pass out of the body, and it is easy to get stones. Nowadays, stones are easy to deal with, and only need to be broken with a machine for mild cases, and surgery for severe cases.

　　 Stone mill was born in the Jin Dynasty!

　　 You can still see the shadow of stone mills, most of them are collected, and grain processing is now mechanized.

　　 More than half an hour later, the stone mill is finished!

　　 Zhao Yunxiang stacked two discs together to form a stone mill, and tested it with some granular pottery fragments.

　　 "Isn't this for crushing grain or smashing bamboo chips?" Han Qianluo was a little puzzled after seeing Zhao Yunxiang's operation, "Why crush the pottery fragments? These are all soil?"

"Yes!" Zhao Yunxiang explained, "We had some failures in firing pottery last time. There are several reasons. The first is because the clay was wet and could not wait to dry in the shade, and the second was because the quality of the clay was insufficient. If you add some pottery powder, the effect will be greatly improved."

　　 "There is this kind of operation?" Han Qianluo is quite knowledgeable, but Zhao Yunxiang knew so much.

　　 "Hmm!" Zhao Yunxiang quickly pushed the grinding disc, while Han Qianluo methodically added pottery fragments, and finally got a lot of reddish brown powder, these are pottery powder.

After 　　 is mixed with the pottery, it can effectively prevent the pottery from cracking during the firing process.

　　 "Lin Qingyu..." Han Qianluo gathered the pottery powder together ~www.readwn.com~ with leaves and gave it to the twins.

　　At this moment, the twins have dug a lot of red-brown clay from the clay pit.

　　 "Mr. Han, what's the matter?" Lin Qingyu wiped the sweat from his forehead and asked panting.

　　 "Zhao Yunxiang said, pottery is not easy to crack when added to this." Han Qianluo put the pottery powder on the ground.

　　Beside the mud pit, there are a few slates. These are all obtained from the box. They are about the island captain’s sister-in-law.

　　 is useless now, just use it to put clay or something, because it is very flat and it is not easy to be mixed with sand.

　　 Soon, a few pottery pots were completed, and Zhao Yunxiang made a very special container by himself, which is like a thickened pot. According to Zhao Yunxiang, this is used to smelt gold!

　　 The wet clay pots were carefully put into the kiln. Now it must start to ignite. The heat of the flame will gradually take away the moisture in the clay.

　　 The production of this thing can be regarded as omitting a dry process, so I am afraid of cracks.

　　Ignite the furnace and seal the furnace!

　　 Zhao Yunxiang washed the pottery powder in the stone mill with sea water! !

　　 "What about the bamboo you made in the sun?" Zhao Yunxiang is ready to make bamboo pulp. The first step in making bamboo pulp is to crush the bamboo and make it into powder as much as possible.

However, dry bamboo has extremely low toughness, is very brittle, and is easily damaged. It can be turned into sawdust by grinding it for a while. After it has become sawdust, it can be done by adding a chemical substance that exists in the forest. Make bamboo pulp, and then make toilet paper!
