Martial Arts: Traveling to Another World and I Am the King

Since this is a world where the strong are respected, what are you talking about with me? Use your strength to speak to me! I, Lu Wuji, don't need you to understand what I do, as long as I have a clear conscience... Those who achieve great things don't stick to trivial matters. I just want to live a better life. What's wrong with me? Sorry, I am a killer, I only care about the results and not the process. This novel and its characters are purely fictitious.
