The Blue Star entered the Age of Transcendence, where everything evolved and demonic beasts were rampant. Human beings awakened the star soul in evolution, so as to fight against the ravaging demon beasts. Zhou Xuan, who was working at the Demon Tower, accidentally awakened the unscientific check-in system. [Check in on the ancient beast, and obtain the Flood of Power. Check-in on the Weed Spirit, the star soul evolves into Nine Leaf Sword Grass.] Thousand-year Xuan Turtle, Ten Thousand Year Sea King, Immortal True Phoenix, and Heaven Swallowing Divine Dragon all became his check-in targets. "Ding, target found - Heavenly Dao, do you want to check in?" "Ding, you successfully checked in on Heavenly Dao and obtained the Law of Heavenly Dao." Heavenly Dao: Hmm? WTF? That day, when the demon god awakened, Zhou Xuan used the grass as a sword, and with a single sword, he shocked the world and cut the demon god into ashes.
