However, no one dared to log in to the “prehistoric land”, which was regarded as a forbidden place by the global log-in.

Chu Feng, who knew the plot of the prehistoric world, logged in for the first time and chose the prehistoric world to start his supernatural path.

While others are still working hard for a fruit of ability in the sailing world, Chu Feng has become the emperor of the prehistoric human race.

Chu Feng: Almighty and omniscient, really cool!
