I am Tianchen, a person who has been at the top since he was born, but he inexplicably traveled through time before he could inherit a family worth tens of billions. To be honest, I am confused. Douluo was reborn and got a sign-in system. Looking at the attribute panel of his battle against the five scum, Tianchen fell into deep thought... Douluo World is just the beginning, just a starting point. It will be followed by Dou Po, Yuan Zun, Swallowing the Starry Sky, Perfect, Covering the Sky, Great Desolate, etc., So stay tuned.
