My classmates chose martial arts and fantasy, but I chose the prehistoric world.

A young man from Earth travels to the Blue Planet and happens to be on a day to choose between three worlds: Wuxia, Xianxia, ​​and Primordial World. While others choose Wuxia or Xianxia to save their lives, he chooses Primordial World, which has a 100% mortality rate!
The whole school was in an uproar, his mother fainted, the news broadcast it, and people said he had gone mad.
No one knew that the primordial world was completely foreign to the people of Earth. But what this Earthling had in his mind was the complete "Nine Revolutions Profound Technique" and the "Encyclopedia of the Primordial World".
One year later, you will either become an immortal and return in glory, or your remains will be lost forever and be buried in the primordial wilderness!
