Divine Desert Island Survival System

　　Although Zhao Yunxiang knows how to mason, but there is no chisel here, he will not do stone grinding by himself!

　　Stone mills are very common in rural areas. Zhao Yunxiang’s father also collected a few, which he kept in his backyard.

　　 In the pergola not far away, a slightly rough stone mill was lying there quietly. This is a water mill, very suitable for making soy milk.

　　 Of course, Zhao Yunxiang doesn't have beans, he just wants to make toilet paper.

　　 summoned a few female savages, women basically do not participate in the construction of the tribe, just do some light work.

　　 Of course, there are still a few older uncles who can't do too tiring work, and simple grinding is fine.

"This is called a stone mill. It is used to grind grain. I have grown a starch-producing food. After a good harvest, I can make grain powder." Zhao Yunxiang said, "Now, I will teach you how to make it. Wood flour."

　　 Well, it is indeed wood powder, which is what wood powder means.

　　 "Boss, what is this wood flour used for?" an old man asked.

"Wood flour can be used to make wood pulp. After the wood pulp is processed and dried, it becomes paper. The thickness of the paper depends on the amount of wood pulp." Zhao Yunxiang thought of paper and showed a happy expression. "With paper, we can rest assured It's rubbed."

　　 "Don't worry about the long barbs on the leaves?"

　　 "No more leaves!" Zhao Yunxiang nodded with certainty. The savages present cheered for his confirmation.

　　 "Long live the boss!"

　　 "The lord is amazing!"

　　 "Big guy is awesome!"

　　 They have a fascinating trust in Zhao Yunxiang, and he believes all the wild people.

　　 Many branches were dried in the open space of the tribe. Most of these branches became very dry, and they were carefully selected by Zhao Yunxiang, and they were all non-toxic.

　　 Of course, even if it is poisonous, after Zhao Yunxiang's production, the toxicity will be neutralized.

　　 After all, he is an assassin and can make drugs!

　　 Being proficient in drug making means knowing poison, and relatively detoxifying.

　　 "Chop these branches with an axe, try to chop them into small pieces, and use them later." Zhao Yunxiang said.

　　 The older savage is holding a bronze axe, and this axe also has many gaps. If it is replaced with iron, this situation may not appear, but there is not much iron ore now, and the smelting technology is not up to smelting iron.

　　 Therefore, I can only hope that the ore surveyors can find lead in a short time. With the addition of lead, they will be successfully made into bronzes, and then bronze weapons can be made in large quantities.

　　 A large number of branches were chopped and chopped by savages to make many small pieces of wood. Female savages also joined the production of small pieces of wood. They broke them with their hands and threw them into the vine woven basket.

"Very good, then we can crush it." Zhao Yunxiang pointed to the stone mill. "The structure of the stone mill is composed of two discs. There is a bronze shaft in the center of the disc, which can drive the upper disc to rotate. ."

　　 "And the upper disc has a hole, you can throw in grain particles or wood chips, so that in the process of pushing the upper disc, the two stone mills rub against each other, and all these things will be crushed."

　　 Zhao Yunxiang explained while instructing the female savage to start the operation.

　　 He teaches what he has mastered to the wild people. These people have very flexible minds and accept things very quickly.

　　 "Wow..."

　　 The stone mill pushed and started to spin slowly. A savage one after another poured wood chips into the stone mill hole.

　　 After the special friction and squeeze of the stone mill, the dry wood chips gradually turn into wood powder.

　　 These powders are packed in a huge pottery jar, yes, it is the pottery jar!

　　The industry here has never stopped. After learning to make pottery, the wild people began to try to make huge pottery jars.

　　 has failed many times at the beginning, all because of the cracks caused by the insufficient purity of the raw materials. Under Zhao Yunxiang's teaching, the savages completely broke the cracked pottery and mixed the powder into the clay.

　　 The pottery jars fired by such an operation are basically complete, and the success rate is as high as 80%

　　 For an entire hour, the female savages took turns to grind, crushing a lot of wood powder, almost made a pottery jar.

　　 "Okay, it weighs 30 kilograms!" Zhao Yunxiang nodded in satisfaction. He was quite surprised by the efficiency.

　　 You need to know that the weight of sawdust is very light. What is the concept of a full 30 kg? The toilet paper made from these can last for a year, right?

　　"What do we do next?" The old man held up wood powder with his hands. Most of these things are powder, and some are some wood stubble, but this does not affect the production of toilet paper.

"Ignite, start firing!" Zhao Yunxiang was prepared for a long time. He prepared a section of tree roots in advance. This kind of tree roots contain special chemical effects, which can greatly promote wood pulp, and the effect is better under high temperature. .

　　 The sap of this tree root is toxic, but after dehydration, the toxicity will be lost with the water. As long as the toilet paper is dried, it is safe.

　　 After dozens of minutes, a tank of steaming wood pulp was finished. The color of wood pulp was a little dark and grayish-yellow. This is the natural color of paper.

"These are wood pulp. Now we need to scoop out a little wood pulp with a ceramic spoon and spread it evenly on this model." Zhao Yunxiang holds a wooden board with one hand. The board is about 1 cm thick, 2 meters long, and wide. It is 20 cm.

　　 There is a flat depression on one side of the board, and the depth of the depression is 1 mm.

　　 In order to prevent the wood pulp from showing signs of bonding, Zhao Yunxiang deliberately brushed a layer of turpentine inside the mold. This layer of grease is very smooth, which will prevent the wood pulp from evaporating moisture. uukahnshu.com left the toilet paper sticking to the mold.

　　 At the same time, because of the strong water barrier properties of turpentine, the mold is almost 100% covered by turpentine. Therefore, the water in the wood pulp cannot penetrate the wood, which is more conducive to the rapid evaporation of wood pulp.

　　 "Okay, now you come to the operation." Zhao Yunxiang still guides from the side, so that the wild people can fully learn this technique, so that future toilet paper production will not be so troublesome.

　　 Use a spoon to slowly pour the wood pulp into the mold. This wood pulp water with a depth of 1 mm will quickly evaporate under sunlight, leaving only the dehydrated wood pulp in the end.

　　Because wood pulp is insoluble in water, when the water is completely evaporated, a piece of paper can be obtained.

A few minutes later……

　　 A slightly damp piece of paper was taken out of the mold by the savage. This piece of paper has been completely formed, the texture is somewhat rough, and there is no break after folding.

　　 "It's a success!" Zhao Yunxiang was overjoyed, "You have made toilet paper! Hahaha!"

　　The wild people were surprised to see the transparent toilet paper. Through this paper, you can clearly see the larger particles of wood powder.

　　 "It's so thin...Will it be pierced?" A savage asked.

　　 "Of course one layer will be pierced, but what about the third layer?" After Zhao Yunxiang folded, he found that this was almost the same as most modern toilet paper.

　　 The toilet paper was made, and Zhao Yunxiang was just about to rest in a hammock, and then he heard someone rushing towards him. .

　　 "Lord, something happened, the big thing is not good!!"

　　 "Xiaoqiang? Didn't I let him go out with the mineral surveyor?" Zhao Yunxiang frowned suspiciously, and his face became extremely gloomy!
