Sci-Fi: Awaken! the Road Is Complete!

Duan Chen has many identities, such as "a loser in a certain city who did nothing until he died of old age." Or "a perverted demon who burns, kills, and loots!" "A demon king in a certain world who destroys the world." Or "a playboy and a scumbag." Or "a lover who will remain together until death", "or a resentful woman who spends her whole life with resentment" and so on. In the end, thousands of incarnations merge into one! Cutting off thoughts and desires is the way! (The protagonist just gave up his thoughts and desires, which does not mean he is inhumane, but only kindness and compassion are left in his humanity, and almost everything else is lost.)
