I recommend you the " Heavens Substitute Training System ". The main character of this book is Chu Haojin, and the finger is the Heavens Substitute Training System. In this book, Chu Haojin had different identities and deeds in different worlds. For example, he was the hero of Chu who assassinated Ao Bai and Wu Sangui in "The Deer and Cauldron", and the master of the Seven Absolutes Immortal Palace who dominated the list of famous people in the world of martial arts in "Tianya Mingyue Saber". In short, Chu Tianhe in this book traveled between different worlds and became the god of the heavens, showing the infinite possibilities of his journey. I hope you like my recommendation.
