Human Martial God

Zhao Xian traveled through time and when he opened his eyes, he discovered that he could only live for two hours. Zhao Xian could only work hard to complete the task. What? Kill demons? I'll come. What? Bullying? I'll clean it up. What? Do one good deed a day? That's your duty. Don't get me wrong, it has nothing to do with lifespan. I, Zhao Xian, am such a warm-hearted person.
