Picking up a Dragon from the Trash Can

Xiao Zhaotian traveled to the Beast Control Blue Star, but awakened the worst F-level talent. During the contract ceremony, someone else summoned a tiger and a lion, but he was entangled by a phantom thunder snake that came out of a trash can. "Ding! The god-level ancestral system is activated. Please feed the host diligently and unlock the ancestral dragon bloodline!" Seeing the Phantom Thunder Snake crazily devouring the beast's core, Xiao Zhaotian was about to cry without tears: "Ancestor, please be merciful!" One day, the scales of the Phantom Thunder Snake glowed with purple-gold luster, and a small bump appeared on its head. The school beauty exclaimed: "Why is your snake... Glowing?" Xiao Zhatian smiled mysteriously: "No, it is preparing to transform into a dragon!"
