I Am Truly Not the Main Character

Niu Chang reincarnates into a new world. Naturally, a favorable path is laid out for him as a reincarnator. However, unfortunately for the world, he personifies the very definition of heartlessness. Family relations? Morality? They hold no importance to him. All that matters in the end is whether they will benefit him on his path to immortality. From the moment of his reincarnation, the world and its inhabitants are doomed to suffer many calamities.
