"Bows and arrows, bows and arrows are useful for hunting, for protecting oneself and for one's family. Pen ~ fun ~ pavilion www.biquge.info fishing nets can also be used to catch fish. Won't go hungry. Xiao Mumu used a little immature language to describe what he thought was useful in his cognition.

After Xiao Mumu's words, Yao Ran nodded, thought for a moment and said, "That's right, bows and arrows and fishing nets are all useful things. Yao Ran affirmed Xiao Mumu's answer. Xiao Mumu showed a smug expression, but Yao Ran's words made Xiao Mumu understand again.

"However, who taught you the making of bows and arrows, the making of fishing nets, and how should bows and arrows be shot accurately?"

Xiao Mumu's competitive spirit was stimulated by Yao Ran, and as soon as Yao Ran's words fell, he said, "Bows and arrows and fishing nets were taught by the patriarch teacher, and Abba said that bows and arrows need to be shot a lot to be accurate." Mu Mu can also shoot arrows. ”

Because all the preparations have been completed, and the next step is the stage of large-scale construction, so Yao Ran was in a good mood today, and said to Xiao Mumu with a smile, "If the bow and arrow want to shoot accurately, there is a shortcut, such as the impact of the wind on the arrow, when the wind blows through and you shoot directly, is there a deviation." ”

Xiao Mumu nodded, just because he had shot arrows himself, so he knew that when the wind came, the arrows he shot would not hit the trees, so after Yao Ran spoke, Xiao Mumu gave a positive expression, and he was full of anticipation, waiting for Yao Ran to teach him the secrets of how to be a marksman.

"So how do we determine which direction the wind is blowing from and how strong it is blowing?" Xiao Mumu opened his mouth and stopped talking, and finally three words popped out of his mouth: "I don't know!" ”

"We pulled the hem of a piece of rope into silk and hung it above the bow, and we could see it when the wind came out, as long as it was just a little more distance towards the upwind. If we write down such archery skills in the book, will more people know how to shoot arrows when the wind blows, so that everyone will no longer have to think about it by themselves? ”

Xiao Mumu blinked his clear eyes, and he didn't know if he was thinking about how to shoot arrows, or Yao Ran's last sentence, which was made into an archery book.

Yao Ran was very satisfied with his newly recruited little apprentice, and children who were good at thinking were definitely not stupid children. As long as you study diligently, you will inevitably be a useful person in the future.

Ignoring Xiao Mumu, Yao Ran said to Wei Jin and Wei Dian: "You have done something that will work for a thousand years, and what these papers will carry in the future is a priceless knowledge inheritance." ”

Of course, the two guard knights didn't understand Yao Ran's words, but the general meaning should be to praise themselves, and the patriarch was saying something that everyone could only understand, but didn't know what he meant. I had to smirk and get shy.

Yao Ran patted the shoulders of the two. Yao Ran thought for a while, took out a piece of carbon black from the leather pocket he was carrying, and the chicken quills he had made before, dissolved some carbon black, and wrote on a flat stone slab, "Zero 1234567890." Then he wrote, "You, me, him." ”

He picked up a long thumb-sized stone on the ground and handed it to Wei Jin, who said, "Buckle the paper to the clay, and then leave the font behind, and deduct the rest of the place below." More and then firing for a day and a night. ”

"You have learned these words, and then take this piece of paper to me after you do it, and I will continue to write it for you, and the work of paper production must be carried out continuously, how many pieces of paper can be produced every day now?"

Wei Jin took the stone in Yao Ran's hand and the paper on which he could write his words. Answering Yao Ran's question, he said: "If you continue to make paper every day, you can probably produce about 3 pieces of such large paper every day." ”

"How many of you are making paper now? What is the division of labor? How many people are there who break wood? How many people are boiling pulp? How many people are there who fish and dry paper? ”

Wei Jin hurriedly replied, "There is no division of labor now, which step will you do at that step?" There were 8 people in total. ”

Yao Ran touched the retinal system and pondered for a long time, Wei Jin and Wei Dian didn't know what they had done wrong, was the patriarch angry?

That's right, Yao Ran is indeed a little unhappy, only three pieces of paper a day are enough to do something, this kind of division of labor has to be arranged by himself, it's really a big head.

"Well, when I went back, the eight people were divided into two groups, because breaking wood was a manual job, and five people were divided into five to perform it. It's no problem to cook pulp for two people and 6 pots at the same time. Drying paper can be done by one person. As you said, everyone will do everything together, not only will it not improve efficiency, but it will also keep you busy enough. Yao Ran said.

Wei Jin, Wei Dian immediately understood after hearing this, yes, when working, beating wood into foam is the slowest and most exhausting work.

The two of them hurriedly nodded and said, "Respect the life of the patriarch!" The two of them stroked their chests in unison and saluted.

Yao Ran saw that the work was arranged, although the efficiency was not high now. However, after the adjustment, the number of products will be much higher than that of the product.

"Come with me, it just so happens that you guys are also here, and I will show you the new weapon of the family." Yao Ran turned around and walked in the direction of the huge tree trunk.

The main trunk, which had been stripped of its bark, was exposed, and the beige trunk looked as if it had been jaded in the sunlight. When he got closer, Yao Ran dissolved some more graphite and put a rope with a triangular bottom pendant wrapped around one end into a bowl that was being smeared.

After dipping the ink, Yao Ran arranged a student above the torso of the entire tree. Hold the hanging wire yourself. The other end was held up to Lang Yan, who was standing on the tree.

Yao Ran himself squatted down, hooked the middle waist of the ink line and pulled it up to a high position, and then hit the ink mark on the trunk of the tree, and after doing it on one side, he went to the other side This time Yao Ran turned over his fat body and went to the trunk of the tree. There is no way to master such an important work, and only Yao Ran can do it himself, and this is because of the retinal system. Why this center bearing should be so accurate thickness.

Because such a large trunk serves as the center point. When cutting, the rotation will cause uneven rotation. Or it may directly cause the waterwheel to fail to rotate after installation.

After playing the tangent lines on both sides, the fifty centimeter thick one that is ready to be taken out in the middle is drawn, and the central bearing piece is drawn, and 6 lines are marked in a row.

The preparation of the cutting work began, a more than one meter long, thirty centimeters wide flat long zigzag, the handsaw was taken out, which was basically consistent with Yao Ran's description, thanks to the efforts of Hua Tuo and Yao Huo, although Hua Tuo was only obsessed with medicine and herbal medicine, but on the way to the clan land, he followed Yao Ran to learn together, and the process of making bows and arrows was still very rich. plus Yao Huo's experience in making pulleys, as well as the help of Xiaoping and Langyan. The workmanship of this handsaw is still very good.

After Yao Ran adjusted for a while, he said, "Come on, open the saw!" (To be continued.) )
