Born as a saint, he was supposed to be the beloved child of heaven and the co-owner of all laws. But in this prehistoric world where saints are inferior to dogs and Daluo roams everywhere, the protagonist Ji Hao's identity as a "born saint" has become the biggest original sin - he is the most perfect "Tang Monk Flesh" and "Elixir of Enlightenment" in the eyes of all powerful men. At the beginning, he was blocked by the enchantress Su Jiu'er, who tried to "pluck his yang and replenish his yin". In order to protect himself, Ji Hao relied on his natural affinity for the Tao and his wit beyond ordinary people to open a unique path to enlightenment. He played with the hypocritical Taoist master, punched the ancient demon god, subdued the mythical beast, and refined the treasure of chaos. In life and death crises one after another, he discovered that the so-called "Heavenly Way" was actually the biggest mastermind behind the scenes, treating all living beings as stupid dogs and saints as pawns. In order to protect the people he loves and break the shackles of fate, Ji Hao resolutely embarks on the path of both good and evil. When the kindness of a saint cannot save all sentient beings, he turns into a demon, slaughters all hypocrisy, proves the way through killing, and finally fights with the will of heaven to reshape the order of the world!
