Fortunately, he is bound to the infinite evolution system. "Ding! Congratulations to the host for obtaining the bloodline of the ancestral dragon!"

The third evolution, the road is reversed, and all souls are wailing! At this moment, as soon as the ancestral dragon of heaven and earth appeared, the whole world was trembling... Xiao Han: "I just swallowed a few mouthfuls, why is it so dark?"
