The so-called angular momentum boxing is actually just a joke played by Chengying. When he told Dugu Bo advanced physics, he obviously couldn''t understand it. Chengying used martial arts as an example.

    For example, someone punched you, but you followed his strength and dissolved his strength. Here, the law of angular momentum was applied. Then, according to the ways of Taijiquan in previous lives, the film told Dugu Bo, and shamelessly named this boxing as angular momentum Boxing

    At the beginning, Dugu Bo was just joking, but he didn''t want to be true, and he also figured out a similar set of boxing. This collision, whether Dugu Bo''s boxing is effective or not, he must be seriously injured.

    He can admit defeat with dignity when he is up to the present level. Even if he admits defeat now, Tang Chen will be convinced of his ability, but it is obvious that Dugu Bo just wants to fight for this breath.

    While Chengying and the ice emperor rushed out, Dugu Bo''s palm also touched Haotian hammer. The terrible force made the bones of his arms creak.

    But he still endured the sharp pain. One foot drew a circle on the ground like a compass, driving himself to rotate like a top. While staggering the front of Haotian hammer, the next palm of the high-speed spiral patted Tang Chen''s chest.

    The strength he just received from Haotian hammer was returned to Tang Chende''s chest. No one knows more about the power of Tang Chen''s blow than himself.

    The heavy blow from his chest even made him unable to hold the hammer. The whole man flew backward and rubbed a gully on the ground.

    Dugu Bo was not much better. The forces acted on each other. Under the reaction force, he also flew out. Fortunately, he was caught by the film in time. Even so, his state was very poor, including arm fracture and mouth and nose bleeding.

    "Teacher, I won!" Dugu Boqiang held on for a while, and then he could not hold on any longer and passed out in a coma.

    Chengying looks at Tang Chen, who is still alive and kicking with the back of his neck skin carried by the ice emperor on the other side. After thinking about it, he still doesn''t intend to tell Dugu Bo the real result of the battle.

    Just then, Tang Chen, who was carried by the ice emperor, looked at Dugu Bo with respect and said, "I lost. When sister Chengbing just caught me, she dispersed the poison gas around me. Otherwise, I just fell within the scope of the poison gas. There is no doubt that he was the first of his peers to defeat me."

    When Chengying heard the speech, he couldn''t help but look at Dugu Bo more. He even calculated to this extent in order to win. I think he must be very unwilling to be the tail of the crane in the title duel in the original book!

    Chengying was still meditating, but Tang Chen broke away from the ice emperor''s hand, kowtowed the first line of worship in front of Chengying and said, "master, please accept my disciples! Please teach my elder martial brother the last move! "

    After receiving Tang Chen''s salute, Chengying held him up and said, "what Dugu Bo just used is not the self created soul skill I taught him, but the self understanding from the physics I taught him. If you are willing to learn, you can teach from this physics."

    Tang Chen looked at Dugu Bo, who was carried on the stretcher by the medical staff in white coats, nodded and said, "please teach me!"

    By the way, although Chengying doesn''t know any medical skills, she still has some medical knowledge. After hiring some local doctors and unified training, the hospitals opened in Tiandou city have become more and more similar. Most of the people who come to see doctors are injured by fighting souls or hunting souls. It can be said that they are familiar with dealing with Dugu Bo''s non serious fractures.

    Without knowing the formula of Mabei powder, the anesthetic provided by Chengying to the hospital can only be ether made by laboratory method. Ordinary soul masters can''t afford it, but it''s another matter for their disciples.

    After sending Dugu Bo to the hospital, Chengying also began to take out paper and pen to explain physics to Tang Chen.

    "First of all, you have to distinguish a problem, that is, whether the movement of an object needs force to maintain..." the first conclusion drawn from the academic pit left by Aristotle is that the movement of an object does not need force to maintain, which is quite counter intuitive, but Tang Chen can''t refute it.

    The difference between mass and weight, speed and acceleration, and iron balls of different masses falling from the same height, which takes less time

    The explanation was accompanied by the experiment. Tang Chen was stunned. But the more he brought into this theory, the more reasonable he felt. Thinking that what people took for granted for thousands of years, even tens of thousands of years, was wrong, he couldn''t help but marvel at his teacher''s profound knowledge again.

    Chengying talked about it all afternoon. His mouth was dry, which only made Tang Chen understand the meaning of quality. Even so, Tang Chen still had an expression of meaning.

    "Teacher, what you taught me is the unchangeable truth in the world, but what is the connection between these and what you said, changing this era to a happy land where the tiller has his land, the home owner has his house, the old have a sense of security and the young have a sense of education?"

    Chengying smiled and said, "these are the cornerstones leading to a new era. Before the teacher''s permission, don''t tell others what you see and hear today."

    With that, Chengying took Tang Chen to the backyard. Every afternoon, the ice emperor would take some time to play shooting games in the shooting range. As soon as Tang Chen was pulled over by him, he saw an ice emperor with open waist, short sleeves and super shorts, holding two silver metal objects he didn''t know in both hands, hovering in the yard.

    Then he heard twelve consecutive bangs, some similar to the firecrackers from Tiandou city recently.

    At the same time, in the backyard, the twelve targets around the ice emperor were pierced one after another, and each target was a hole at the ten rings.

    Then the ice emperor landed, turned the two revolvers in his hand, and put them into the holster at his waist.

    "How''s it going? What about? I just did this round shooting, isn''t it particularly handsome! " Just as soon as the pistol was inserted into the holster, ice emperor changed from the handsome western female cowboy to the little Lori.

    "Well! It''s so handsome. It would be even more handsome if you didn''t shoot all the bullets I practiced shooting! " Then Chengying picked up the ice emperor and put her on the windowsill.

    The ice emperor''s two small feet are worthy of swing, and his big eyes are watery, staring at the background, as if to say: "is bullet important or am I happy important?"

    Chengying shook his head reluctantly, took out a revolver at his waist, took it out and demonstrated to Tang Chen: "I told you before that two points determine a straight line, so when aiming, we should make the target and the collimation three points and one line."

    With that, the photographer aimed at the distant target with a fairly standard gun action with both hands, and then pulled the trigger.
