Become a Bad Guy and Save the World

When Yue Chuan woke up, the world went crazy. There were twisted and depraved time-travelers everywhere, but he became the only "alien". The world is in ruins and the rules are cruel: to survive, you have to join in the evil; to save the world, you have to start by being a bad guy. His golden finger is simple and crude: spend money to become stronger. Money is hard to make in this world, and evil... Is even harder to do. Until he discovered that the most indispensable thing in the world is evil people - and harvesting evil people is the shortcut to saving the world.
