Yang Yiming was born in a poor family at the bottom of the family. His father died young and his mother was seriously ill. He has lived in bullying, poverty and indifference since childhood. He was trampled on by the powerful and bullied in turns by gangsters. He could not even save the life-saving money to buy medicine for his mother. He once firmly believed in kindness and hard work, but he was forced into desperate situations time and time again by the world, and saw with his own eyes the unfairness of heaven and the reversal of good and evil. When all the patience failed to buy any chance of survival, the young man completely awakened, abandoned kindness for ruthlessness, and established power with blood. From a lonely ant, he stepped into the turbulent rivers and lakes step by step, recruiting brothers, seizing territory, fighting against powerful people, and resisting powerful forces. From a bereaved dog in a shanty town, he counterattacked and became an underground dragon with one hand covering the sky. He does not believe in fate, does not kneel to the sky, and uses his ruthless body to reverse fate. He uses the knife in his hand and the power at his feet to fight a way out for himself and all the people at the bottom who have been crushed by fate, and finally lives his own way of heaven and his own justice.
