As a descendant of Mohism and a pure science and engineering talent, Xiang Lishi is extremely eager for these hard core knowledge. Although Mo Qiong is very basic and has no substantive technology, it has opened their eyes. Many things they didn''t understand in the past are suddenly connected 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 we understand this point, the whole system of classical physics can also be deduced by our own reasoning.


    Taking this theory as the core, Xiang Richter found that many 10 million things he didn''t understand were explained at this time, but then more doubts were born.


    What doubts bring is new attempts. The studio does not teach them technology, but a scientific and technological revolution is actually taking place.


    Chengying has always felt that Chen Xi, as a jumper, is really too salty fish. Economics is indeed very useful, but there will always be no basic physical attempt, right? For so many years, let alone the radio, the walkers didn''t even point out the technology of cable telegraph. What the hell is it?


    This thing can''t be said to have no technical content. It''s really a technology that can be pointed out by primary school students. Even if the prototype is very simple at the beginning, it won''t take long to improve with a group of people. In contrast, it''s really laborious and thankless to engage in Tiandi Jingqi remote communication, which doesn''t even have a basic theory.


    The only explanation that Chengying can think of is that Chen Xi is a pure liberal arts student and belongs to a type that doesn''t even have a foundation in this regard.


    Electricity is a wonderful branch of the science and technology tree. For an orthodox science and technology tree, you should first point out the steam engine, train enough industrial workers and improve the processing accuracy, and then you can spy on other heat engines. In short, there must be a precision limit.


    The motor is a kind of technology that takes no trouble and can be rubbed out by primitive people. The only thing that limits the emergence of the motor is the time when human beings discover electromagnetic induction. Therefore, the source of power for the film is located on the motor from the beginning.


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


    Just like Ma Chao, he has the ability to discharge when he is struck by lightning. Of course, it is impossible that lightning is stored in his body. How much energy can lightning carry? There is no doubt that Ma Chao''s internal Qi can be transformed, or guide the essence of heaven and earth into thunder.


    For the research in this field, the contractor has only made theoretical reasoning, which is completely feasible in theory. In the future, the high-speed railway can extract the essence of heaven and earth and convert it into electric energy to supply power to the motor.


    Even this will lead to cheap electric energy and change the process of metal smelting. In ancient times, most metal smelting relied on the reducibility of carbon, which will inevitably lead to impurities in the metal, and many metals with stronger reducibility than carbon will be difficult to smelt.


    If the electric energy is so cheap to a certain extent, it is not impossible to smelt by relying on the hydrogen obtained from electrolytic water, or directly power on to control the gain and loss of electrons.


    When he was pulled into a dream the next day, he began to learn electricity. The most convenient thing to have a class in a dream is that he can easily demonstrate to the students.


    In the dream space, everything can be changed. If the filmmaker wants to shape a rocket with memory, it is a piece of cake. Therefore, all Xiangli people have the opportunity to practice. Watching copper wires wound into coils, and then turning on the magnet, they can make another section of copper wire generate current. For a time, it is like discovering a new world.


    At first, some people thought and asked why there was current, what was magnetic flux, and why cutting magnetic induction lines would produce potential difference. One question was put forward and answered. Compared with boring mathematics, Xiang Richter''s science and engineering man dissipated a type that you like to get started directly.


    With their study, they believe that Mo Qiong is their Mohist ancestor. Some even doubt whether Mo Qiong is disguised by a generation of giants. Otherwise, why can they know so much.


    Chengying found that this group of people learn very fast, not as Chen Xi thought. Because of the limitations of the times, their ability to accept knowledge has been reduced, which can only be attributed to the fact that they teach a group of men of science and technology.


    After teaching the basic part, Chengying did not continue to teach them theory. His goal was to win the gamble and help the Han Empire establish a scientific and technological system.


    To achieve the goal of winning gambling quickly, the simplest way is to point to some off the beaten track war technology.


    If we climb the tree of science and technology step by step, the improvement of war ability is not fast.


    So, after his fourth dream, Xiangli began to come into contact with some technical things.


    The war of this era is difficult to become a torrent of steel and the form of tank tracks in a short time. Among other things, the muscle men of the first auxiliary legion of Rome can easily throw the tank as a sandbag.


    Coupled with the technology of warming up, the material strength is greatly improved. Without the use of the heaven and earth essence cannon, it is difficult for the chemical powered shell to do anything about the soldier''s armor. Therefore, the cold weapons taught to Xiang Lishi are not so cold.


    For example, chainsaw sword, high frequency concussion sword and fusion cutting sword are all weapons that can be warmed and strengthened to a certain extent. They won''t suffer as much against armor as gunpowder weapons.


    In particular, the melting and cutting sword must be made of special materials that cannot be heated. In this world, the heated materials are very afraid of heat. Under the high temperature of several Baidu, the warming effect will completely disappear. Therefore, the melting and cutting sword can almost be used as an armor breaking artifact. The strength of this material is outrageous. In addition, it can stir up the warming effect of an opponent, Then there is no difference between cutting armor and cutting tofu.


    Xianglishi was originally born to make weapons. He was naturally familiar with this aspect. After learning it, he found someone to build a smelting furnace the next day, and created a super alloy with strength no worse than that of warm curing materials according to the corresponding ratio.


    With this experience, Xiang Lishi directly started to build fusion cutting swords according to the process learned in his dream. Some members even had large brain holes and began to think about whether to build fusion cutting crossbows.


    Then he was slapped on the back of the head by the owner. Since the crossbow is disposable, there is no need to heat it before launch. When it hits, it will not be over if it ejects fillers that can react to produce high temperature!
