(It's not a harem, it's not routine, it's not invincible, it's not systematic, it's not brainless, it's not a good article, and those who don't like it should beware.)
Han Yan, an orphan whose parents both died, made a living by stealing. He accidentally stabbed to death the gang leader with a reward on his head and became a killer ever since. A mission went wrong, and his hands and feet were broken and he was locked up in a small dark room. As he waited for his fate to end, an electronic synthesized voice sounded in his ears: The player's cold inflammation was detected. Please consider carefully whether you want to participate in the fatal game. This game really kills people. With no way out, Han Yan decisively chose to participate. Unexpectedly, it turned out to be a game of traveling through many worlds and killing a lifetime.
