Chen Yu took the mysterious sapphire bead and the "Hunyuan Book", starting from the antique restoration shop in the village in the earth city, and embarked on the road of cross-border cultivation. He defeated the Shadow Hand organization, which coveted the earth's resources, and used the Green Jade Bead to evolve and break through to kill powerful enemies. Later, he and his relatives and friends were separated when they crossed borders, and fell into the Qinglan Domain of the cultivation world alone. Starting as an outer disciple of the Qingmu Sect, the Qingyu Bead gradually evolved into the Star Bead. He rose to prominence with his heaven-defying ability, killed the evil cultivators of the Blood Soul Palace, and helped the sect to advance until it overcame the calamity. During the tribulation, he was disturbed and fell into the demon world. He used the star beads to purify the demonic energy and control the laws of chaos. The treasure evolved into the chaos beads, and later entered the divine realm to dominate the world and became the chaos god king. In order to eliminate the evil spirits outside the territory, he formed the Hongmeng Guardian Alliance. The Chaos Bead eventually evolved into the Hongmeng Bead. Chen Yu broke through to the realm of Chaos Dominance and quelled the catastrophe of the universe. In the end, he became the guardian of the multiverse, returned to Earth to reunite with his relatives and friends, passed on the responsibility of guardianship, and eventually became the master of the Hongmeng Star.
