Lu Chen, who was in the realm of immortality, traveled through the world of comprehensive martial arts but was trapped in a deep valley. He had to adopt nine spirit beast cubs in order to escape. Fortunately, with the blessing of the Supreme Nurturing System, on the day when the spirit beast transformed, he unexpectedly received the tenth child, who broke through the realm. When passing through Youzhou, because his cub was humiliated, he was so angry that he frightened the prince of Beiliang and Jian Jiuhuang, and even attracted the peach blossom sword god Deng Tai'a to ask for the sword. From then on, he became invincible, stirring up the turmoil in Beiliang and even the world.
