Chen Changan, who was immortal but unable to practice, was persuaded by his master Mu Yunyao to retreat down the mountain and returned to the declining Chen family. He started his spiritual practice with the help of the mysterious fetal bead, accepted his disciple Chen Yunxuan to teach him the emperor-level skills, and traveled to the three realms with the mythical beast Rhubarb in search of the remaining eight fetal beads. On the way, he fought against various forces such as Liu family's betrayal and royal family's obstruction, revealed the secret of the reappearance of the three lists of heaven, earth and people, and his combat power grew against the sky. In the end, Chen Changan and Mu Yunyao finally became a couple, and the Chen family was revived as the first family in the Taixuan world. He will join hands with his Taoist companions to explore the source of the fetal beads and the vast world outside the world.
