Science Invades Another World

Lu Chen, a male majoring in science and engineering, traveled to another world, triggered the scientific communication system, and became a glorious teacher, tasked with spreading modern scientific knowledge in other worlds. Beating and killing me is not okay, but bragging and showing off? This classmate, do you think that learning this knowledge is useless for fighting on the battlefield? Do you think the battlefield is simple? Do you know how to cut people at any angle so that they can be injured but not disabled? Do you know how you can stab an enemy eighteen times without damaging his internal organs? This involves physics and human structure. Do you understand these? This classmate, please calm down and put down the knife. Although practice brings true knowledge, it should be used on the enemy rather than the teacher. You are a wind-type fighting spirit master who can attack from a distance, so you don't need to learn these killing skills? Classmate, do you know how to use fighting spirit reasonably to maximize the damage? Do you want to know about acceleration due to gravity? Do you know what aerodynamics is? What? Don't you listen? Watch me smash you with the Eighteen Dragon Subduing Palms!
