Chu Yuan, a modern social animal, traveled through time and became an abandoned son of the Black Turtle tribe in the ancient times. He was seriously injured and had a broken Dantian. He also picked up a broken egg and hatched a young Black Turtle (nicknamed Gui Bao) with the talent of "cheating".
Bind to the [Prehistoric Infrastructure System], repair the body by swallowing the residue of the innate spiritual veins, unlock the "low-level spirit gathering array" and "defensive barrier", backhand the fellow fish who came to snatch the turtle shell, seize their magic weapon, and shock the small tribe.
Wandering into Yinglong's ancestral land by mistake, he met Yinglong Cangheng who was ostracized by the dragon clan and was seriously injured in seclusion. Turtle Bao accidentally swallowed Cangheng's healing medicine. Chu Yuan was forced to stay and work to pay off debts. The two reached a cooperation agreement of "protecting the cub in exchange for healing."
The elders of the Black Turtle clan coveted Chu Yuan's system and led their clan to encircle and suppress them. Chu Yuan used infrastructure traps (magma trenches and rockfall formations) to kill his pursuers. Cang Heng took action to make up for the damage. The relationship between the two warmed up and they established a "fighting side by side" alliance.
