Douluo live long see

As a descendant of the Mohist school and a pure science and engineering talent, Xiang Lishi is extremely eager for these hard-core knowledge. Although what Mo Poor talks about is very basic and does not have any substantive skills, it has opened their eyes. Things that I couldn't figure out suddenly became clear at this time.

For example, the distinction between mass and weight can be said to be the most core point in classical physics. As long as this point is clarified, the entire system of classical physics can be derived by reasoning on its own. Come.

With this theory as the core, Xiang Lishi found that many things that 1000 million people do not understand, all have explanations at this time, but further doubts are born.

Doubts bring about new attempts. Chengying did not teach them technology, but a technological revolution is actually happening.

Chengying has always felt that as a time traveler, Chen Xi is too salty. Economics and so on are indeed very useful, but there will always be basic physics experiments, right?Travelers have been traveling for so many years, let alone radio, what the hell is it that they didn't even point out the technology of cable telegraph?

It cannot be said that this thing has no technical content. It is really a technology that elementary school students can point out. Even if the prototype at the beginning is extremely simple, it will not take long to improve it with a group of people. Communication, a thing that doesn't even have a basic theory, is really a bit thankless.

The only explanation Cheng Ying could think of was that Chen Xi was a pure liberal arts student, a type who didn't even have a foundation in this area.

Electricity can be regarded as a branch of the technology tree. It is a rather strange branch. In the orthodox technology tree, you must first point out the steam engine, train enough industrial workers, and improve the processing precision, and then you can spy on other heat engines. In short, you must need a precision. limits.

As for the motor, two metal brackets like tree branches, a coil, and a magnet can be turned on and off. It belongs to the kind of technology that primitive people can rub out without too much trouble. Human beings discovered the time of electromagnetic induction, so the power source of Chengying was located on the electric motor from the beginning.

On the one hand, it is because it is easy to start, and on the other hand, it is because the essence of heaven and earth can guide lightning. As long as it is guided and integrated to a certain extent, this electric energy can be used as an energy source.

Just like Ma Chao, he has the ability to discharge when struck by lightning. Of course, it cannot be that lightning is stored in his body. How much energy can lightning carry?There is no doubt that Ma Chao's internal energy can be transformed, or it can guide the essence of heaven and earth to turn into thunder.

For the research in this area, Chengying only made theoretical reasoning. It is completely feasible in theory. The future high-speed rail can completely extract the essence of heaven and earth and convert it into electrical energy to power the motor.

Even this will lead to cheaper electricity, which in turn will change the process of metal smelting. Most metal smelting in ancient times relied on the reducibility of carbon, which led to the inevitable mixing of impurities in the metal, and many metals with stronger reducibility than carbon, It will also be difficult to smelt.

And if electricity is so cheap to a certain extent, it is not impossible to rely on the hydrogen obtained by electrolysis of water for smelting, or directly energize to control the gain and loss of electrons for smelting.

The next day, Xiang Lishi was drawn into a dream and started to learn electricity. The most convenient thing about teaching in a dream is that he can easily demonstrate it to the students.

In the dream space, everything can be conjured. If Chengying thinks, shaping a rocket out of memory is a piece of cake, so everyone in the Xiangli family has the opportunity to practice, watching the copper wires entwined Form a coil, and then turn it around on the magnet to generate current in another section of copper wire. It is like discovering a new world for a while.

Some people began to think and ask, why there is current, what is magnetic flux, why cutting the magnetic induction line will produce potential difference, one after another question was raised and answered, compared with the boring mathematics, the man of science and technology of Lishi's dissipates what you like This type can be directly used.

As they studied, they became even more convinced that Mo Poor was the patriarch of their Mohist family. Some even wondered if Mo Poor was a fake by a certain generation of giants, otherwise why would they know so much.

Cheng Ying found that this group of people learned very fast, and did not have a reduced ability to accept knowledge due to the limitations of the times as Chen Xi thought. It can only be attributed to the fact that he taught a group of science and engineering men.

After teaching the basic part, Chengying did not continue to teach them theories. His goal was to win the game, and helping the Han Empire to establish a technological system was just incidental.

If you want to quickly achieve the goal of winning the game, the easiest way is actually to order some unorthodox war technology.

If you climb the technology tree step by step, the improvement of combat capabilities will not be fast.

Ever since, after the fourth dream, Xiangli began to come into contact with some technical things.

In this era of war, it is difficult to turn into a torrent of steel in a short period of time, and the form of tank tracks. Among other things, the group of muscular men of the Roman First Auxiliary Legion can easily play with the tank as a sandbag.

Coupled with the technology of warming and nourishing, the strength of the material has been greatly improved. In the case of not lighting the cannon with the essence of heaven and earth, it is difficult for the chemical-powered shells to attack the armor of the soldiers. Therefore, what Chengying taught Xiang Lishi is not so Cold cold weapon.

For example, chainsaw swords, high-frequency shock swords, and melting swords are all weapons that can be strengthened by warming to a certain extent, and they will not suffer as much against armor as gunpowder weapons.

Especially for melting and cutting swords, the blade must be made of special materials that cannot be warmed, because in this world, warmed materials are very afraid of heat, and at a high temperature of several hundred degrees, the effect of warming will disappear completely. Therefore, the melting and cutting sword can almost be used as an armor-piercing artifact. The strength of the material itself is ridiculously high. Coupled with the warming effect that can overpower an opponent, there is no difference between cutting armor and cutting tofu.

Xiang Lishi was born in making weapons, so he is naturally familiar with this aspect. After learning it, he found someone to build a smelting furnace the next day, and built a weapon according to the corresponding ratio. A superalloy with much worse feeding materials.

With this experience, Xiang Lishi directly followed the process learned in his dream and began to build the fusion cutting sword. Some members even had big brains and began to think about whether to build a fusion cutting crossbow.

Then he was slapped on the back of the head by the head of the family. Since the crossbow arrows are disposable, there is no need to heat them before firing. When they hit, the filling that can react to generate high temperature is sprayed out, and it's over!
