The Big Turntable of the Alien Super System

Liu Tian fell asleep in a daze, and he actually traveled through time, and there was a super powerful system that could kill monsters and kill people, and it could be upgraded! "You said you have an artifact? Come on, come on, the leader of ancient artifacts will teach you how to be a human being." "You said you are a mythical beast? Ice Dragon King, Five Holy Beasts, Holy Dragon Abu, let him see what a mythical beast is." "You said your bloodline is strong? Sorry, I have Uchiha bloodline, Saiyan bloodline, True Dragon bloodline, Five Elements bloodline..." "All I can say is that everyone here is a weakling!" Many years later, Liu Tian stood on the top and said helplessly: "It's too difficult for me, I'm a weakling." PS: The article is cool and not cruel, and it won't be too invincible in the front.
