Liu Hao, who had a smooth life in the first half of his life, lived a bohemian and idle life every day. He had never worried about his future at all, but who would have thought that fate would play such a trick on people. Once, an old classmate, Lao Tian, whom he had not seen for a long time, came to Liu Hao and asked for help. Liu Hao readily agreed, but he did not expect that this seemingly simple help contained murderous intent.
