The rustling sound of the back and forth cycle continued to fall as the wood chips drifted down at the ends of the log grooves on both sides. The huge log with a diameter of more than 1.50 meters www.biquge.info the pen "Fun" Pavilion has been sawn nearly one-fifth of the thickness, and everyone present is dumbfounded. What kind of weapon is this?

Yao Ran brought too much magic, and the nerves that should have been numb were shocked again. With such a large amount of wood, it took less than a meal, that is, about 10 minutes, to sawn so much, you must know that it took nearly two days to cut down this tree, if there was this thing called a saw when cutting wood at that time. The longest time is half a day to cut down this behemoth.

In the future, if the logging team uses this kind of thing, why do they have to travel so far to pull wood and come back here, and the woods around here can be cut down more than half in a full month.

Of course, Yao Ran enjoyed everyone's shocked expressions, Xiao Mumu and Xiao Gray were having fun, and Yao Ran didn't bother. Still commanding everyone to sawn wood, Yao Ran directly arranged for two saws to start work at the same time.

And I was secretly planning that these common tools would require a lot of production. There is also the production of weapons.

The current population can be sustained by fishing, but it will not be a long-term event if fish becomes a staple food. There is still a need to develop animal husbandry, and farming. When there are no chemical fertilizers and pesticides, there should be multiple developments in the early stage.

In order to have a certain disaster recovery mechanism and disaster resistance. Otherwise, if there are some natural disasters, natural disasters and man-made disasters, Yao Ran, a group that has just been gathered with great difficulty, will die in the cradle.

After Yao Ran stood still, he said to Wei Jin beside him, "Leave me a piece of paper." In a few days, I'll have someone bring you a batch of tools for shredding wood. ”

"Huh?" Wei Jin's attention was always on the chainsaw that was going back and forth, and he didn't hear what Yao Ran said. Yao Ran repeated what he had just said again. Wei Jincai should have left two blank pieces of paper for Yao Ran, and then returned to the high mountain behind Yao Zhai with Wei Dian.

The work of sawing wood is very simple to operate, just pull hard at both ends. Yao Ran asked people to bring tree stumps and flat stone slabs. I began to write on a blank piece of paper, and the title on my head read: "Basic Textbook" in four big characters, and below it was vaguely written mathematics, Chinese, physics, chemistry, nature, and physical education. And so on.

This is a teaching outline written by Yao Ran, and it is impossible to write down so many things to explain on these two pieces of paper, but to do a cadre training class in the early stage, there is a strong memory for the explanation of these things, and he still has two genius apprentices who can do it.

Yao Huo and Jin Ping, who are strong in remembering and learning, still remember the matter of silently writing the clan rules. The education of these two apprentices starts from practice, and then prepares to learn these basic knowledge, which can definitely get twice the result with half the effort.

The other piece of paper was folded in half twice and torn to form four rectangular sheets of paper, which were still very large in size. There are 50 centimeters long and 30 centimeters wide open paper. Yao Ran scribbled on it, did he still write some height, thickness, annotation, or something on the edge of the picture.

After more than an hour passed, two pieces of shafts had been cut and sawed down, until Yao Huo ran to tell Yao Ran that Yao Ran raised his head without raising his eyes and said, "Sawed?" Let's leave it there for now. I'll look at it when I'm done. ”

Yao Huo was obviously attracted by what his teacher painted, and after seeing it, he took a deep breath of surprise and said, "Isn't this a crane?" The teacher drew it so well. ”

Yao Ran tilted his head to look at Yao Huo who was standing beside him, and saw Xiao Mumu who was scratching the belly of Xiao Gray Ash again, and said with a flash of inspiration in his mind, "Yao Huo came just in time, this little doll is your new junior brother, called Lin Mumu, I can just test your understanding of cranes." ”

Yao Ran handed the crane painted on the slate - three views to Yao Huo and said, "Take this picture and tell your junior brother what a crane is and how the crane works." If you understand it, you will be rewarded. ”

Yao Ran is like a wolf grandmother tempting her apprentice. Yao Huo also likes the drawings drawn by Yao Ran, the drawings are simple, clear and clear, and there are detailed data for all the data. This crane was built by himself, so when he took it out and saw the overall design drawings, Yao Huo was very excited.

Yao Huo was about to turn around and walk towards Xiao Mumu with the drawings, but he was almost stupid by Yao Ran's next words.

Because Yao Ran said, "If you don't understand, just draw the picture in your hand a hundred times." Draw while talking. ”

Yao Huo muttered with a bitter face: "Is this what the teacher said about being a strict teacher and a high apprentice?" ”

Yao Ran looked at Yao Huo expressionlessly, but in fact, he held back his laughter fiercely, if he said that he told Xiaoping about the drawings and principles, of course Yao Huo had information that made sense, but it was strange if he could understand it to such a small little guy.

Teacher, if you want me to contact you to draw, can you just say it? Why bother? Yao Huo walked towards Xiao Mumu with a bitter face.

Xiao Mumu found that someone was coming, raised his head and saw that it was his senior brother, Xiao Mumu hurriedly stroked his chest and saluted, but the little gray gray who was enjoying it was not happy, jumped up and then rubbed Xiao Mumu's leg with his head.

Xiao Mumu looked at his senior brother curiously, he didn't know what was going on, and there was still a little gray gray hanging on his legs. Seeing that Yao Huo only frowned, when Yao Huo turned to look at his teacher Yao Ran, he found that Yao Ran had already walked away.

In desperation, Yao Huo did it hard? Holding the drawings in his hand, he waved them like Xiao Mumu and asked, "Do you know what this is?" ”

Xiao Mumu blinked, "As the teacher's eldest disciple!" Don't you know what this is? Xiao Mumu looked at his senior brother Yao Huo with an idiot on his face.

And Yao Huo was already petrified at the moment. It's not easy! "Good! Tell me what this is, if you say it right, I will treat you with courtesy, and if you say it wrong, you kid will be miserable! That's all you have. Disrespectful to the teacher! You will be punished for drawing 100 times! ”

Of course, Yao Huo didn't give it for nothing, this topic given by Yao Ran is too difficult, but he didn't say that he wanted me to paint alone, isn't there a junior brother? Since giving him a lecture, punishment is not the goal, the most important thing is to be able to learn, to understand, and to know what it is and why it is so.

"Little wood! Tell me what is this? Yao Huo tilted his head and turned his face sideways, with a treacherous and successful look, which was quite a bit cheap like Yao Ran.

"My name is Lin Mumu, not Xiao Mu. Do you know what this thing is called? Write it on the ground, and then I say it, lest you deceive me!" (To be continued.) )
