Wearing slippers and pajamas ,Liu Ze traveled to the prehistoric world. He was not an innate creature, not a disciple of Sanqing, and he didn't even have a standard configuration system for time travel. The only thing he could rely on was himself!

There is no destiny in this world, it is just a battle between life and death!
