And this thing is the blueprint of the third-level technology. Pen, fun, and www.biquge.info

The number of these drawings is as vast as the sea, ranging from military supplies to civilian goods. From aircraft carriers, trains and airplanes, to memory cards and even electronic textured boards.

In this, there are only things that Wang Hao can't think of, but nothing that he can't find.

Among them, most of them require a lot of pre-technology materials, and it is useless for him to ask for them, because no matter how complete the information is, it is impossible for him to build a pistol with a hammer and iron ore.

However, there are still many things, although they look high-end and are very mysterious, but with the existing strength, Wang Hao is still sure to make them.

For example, the root cause of the Industrial Revolution, the steam engine.

Downloading this scientific and technological information is bound to make the development of Wangcun change from a turtle speed car pulled by Lao Niu to the amazing speed of a maglev train.

Moreover, the price of these materials is very cheap, and it is the same price point as normal secondary technology. Wang Hao believes that as long as he is given enough manpower, even if the system is always level two, he is sure that he will be able to get in the car and play with the computer in his lifetime.

However, problems also arise.

That's what to do with the industrial pollution caused by the steam engine.

This problem has not been perfectly solved on the earth, Wang Hao naturally has no way for the time being, and there must be a road before the car reaches the mountain. If you really can't do it, you can only follow the old path of the earth, pollute first and then clean up.

Putting this question aside, Wang Hao looked towards the wooden wall. With the help of giants, the length of the wooden wall is increasing rapidly. Even the craftsmen who saw wood couldn't keep up with the speed of the giants, and in desperation, they could only call more than ten people to help them.

Seeing Wang Hao raise his head, Gu Mu finally found an opportunity to interject: "Hao, aren't you worried?" ”

"Worried about what?" Wang Hao stretched his body and asked. Since the last time I lost my temper by the river, the evolution that I had been worried about for a long time did not happen, and my body did not grow as crazy as described in the giant's mouth.

It's just that for some reason, since the last incident, Wang Hao always feels that there seems to be something more in his body, but he can't say what it is.

Gu Mu was a little at a loss, he pointed to the wooden wall, and then to the drawings, not knowing how to speak.

"Say whatever you want, it's the first time I've seen you like this." After the body was stretched, the bone joints all over the body, like fried beans, crackled into a ball, Wang Hao felt much more comfortable, and asked Gu Mu with a smile.

"Don't you worry, can this big village be built with our strength?" Gu Mu said embarrassedly, questioning Wang Hao in person, making him feel uncomfortable.

"Why do you think this way?" Wang Hao asked.

"Because it's too big!" Gu Mu said seriously.

Hearing his words, Wang Hao laughed, and then said to Gu Mu: "Do you remember what I told you last time that everything in this world can be expressed in mathematics?" ”

Gu Mu didn't know why Wang Hao mentioned this again, so he nodded suspiciously.

Wang Hao patted his head, then pointed to the wooden wall that the giant was building and said: "Compared with heaven and earth, we human beings are too small, we can't see far, we can't run fast, if we want to see the world with our eyes, we are too tired, even if we spend our lives, we can't see the world." That's why I'm teaching you to see the world with mathematics.

You see, our new village is a circle, remember when I taught you how to find the area and circumference of a circle? ”

"Remember!" Gu Mu nodded and said, "According to the drawings, the diameter of the new village is about eight hundred meters, so the circumference is two thousand five hundred and twelve meters. The area is equivalent to about 500,000 square meters. ”

Wang Hao grinned and said: "That's right, I only said it once and remember it so clearly, you look at it now, our village has become a set of data, isn't it much more intuitive?" ”

"Hao, I know its area and circumference, what I want to say is that with such a large area, we need countless wood, we need to do countless jobs, there are too few people in our village, we will never be able to finish these jobs!" Gu Mu was afraid that Wang Hao would misunderstand what he meant, so he hurriedly said.

Wang Hao shrugged his shoulders, and then said, "Don't worry, I'm about to say this." You mean that the area is too big, and if we enclose it, we will need too many trees and manpower, and we are afraid that we will not be able to finish it in old age, right? ”

Gu Mu nodded hurriedly, this is what he wanted to express.

Wang Hao smiled and said: "Actually, you are wrong, you were deceived by your eyes, building a wooden wall, in my eyes, is just a small job, and its workload is not even as good as the workload of building an arrow tower." ”

Looking at Gu Mu's face of disbelief, Wang Hao said: "It seems that although you have memorized my words, you have not been able to use them. Today I'm going to tell you why we can't see the world clearly, but math can.

You just calculated that the circumference of the village is 2,512 meters, and I will take the whole number, 2,500 meters.

And then the trees also have diameters, between 30 and 50 centimeters in diameter, and I take the median value, 40 centimeters, which is 0.4 meters.

In this way, a distance of 2,500 meters requires 6,250 pieces of wood six meters long. We choose to use broadleaf pine, those that have grown hundreds of thousands of years of hardleaf pine, we don't use, because it is too thick, it is too wasteful to use as a wooden wall, and the small broadleaf pine with a diameter of no more than 60 centimeters is used, and such a small broadleaf pine, the average height is more than 60 meters. In addition to the more fragile treetops, nine logs can be extracted.

In other words, if we talk about the material, we only need 694 whole trees.

Therefore, the material problem you are worried about has been solved, and the wood stored in the brick kiln alone is basically enough for the construction of the wooden wall.

Then I will give you an analysis of the manpower problems that you are worried about. Indeed, if there were no giants, the construction of the wooden wall would be a bit too large for the manpower of our village, and at that time, I might have chosen to reduce the height of the wooden wall to two meters, because this would be the most time-saving.

But now that there are giants, I don't know if you have counted them, but as we spoke, the giants nailed seven pillars. You convert it into time, and then calculate how long it will take for the giant to nail all the wooden pillars.

Although I haven't calculated it in detail, I know that this time will definitely not be too long. ”

Wang Hao's words were like a thunderbolt from the sky to Gu Mu.

Gu Mu is talented and willing to study hard. Such a blank, even on the earth, Wang Hao has never seen it, if it were not for the fear of the big hand that can steal knowledge, Wang Hao even has the confidence to teach it to be a genius who is even more successful than Einstein. In the system space, any knowledge can be downloaded, and there is no such thing as teaching.

It's a pity, for some reason, after studying with Wang Hao for so long, although Gu Mu has mastered at least the level of mathematics in theory, he has always been unable to integrate it into his life.

But now, Wang Hao's words are like removing the dark clouds that are blocking him, allowing the sun to shine from the sky to his body.

Looking at the giant, when the giant's hand left a piece of wood, Gu Mu began to count. When the giant knocked the second log into the earth, Gu Mu immediately calculated the time required for the entire wooden wall of the village.

In Gu Mu's eyes, the whole world seemed to have slowed down.

Wang Hao taught him knowledge, formulas, all kinds of things, constantly churning in his mind.

A bird appeared from afar and flew in the direction of the village. Gu Mu used his brain a little, and he knew how long it would take for the bird to fly above his head under the influence of the current wind, moisture, and even air resistance, and the force of the sound.

A touch of tender shoots came out of the soil, looking at this young shoot, Gu Mu seemed to see it grow into a towering tree, and in the process of growing up, the wind and sun it experienced, the alternation of the four seasons, are like a fast shot in Gu Mu's eyes.

Turning his head and looking towards Wang Hao, Gu Mu wanted to see Wang Hao who was like a mountain in front of him before. As a result, I saw Wang Hao's anxious face, as well as the shouts that had slowed down countless times and seemed very ethereal.

When it was analyzed according to the vibration of the voice that Wang Hao was calling his name, Gu Mu's eyes swirled for a while, and he gradually lost consciousness.
