My name is Lu Nan, and I'm a reasonable person. It's not your fault that you're ugly, but it is your fault for scaring me. Less nonsense, pay up! Why are you glaring at me? I didn't... I only glanced at you. Oh, you admit to glaring, huh? Now let's talk about compensation for mental distress. Lu Nan, don't push it! Why? If you try to welsh on the deal, don't force me to explain physics to you! PS: This is the story of a modern young man who gradually learns physics after being able to travel to a martial arts world.
