Since the opening of the Dungeon Rifts-- also called D.Rifts or Drift Dimensions, the world has changed. It's become more militaristic and violent-- unpredictable, even. Monsters raze cities and bring diseases that birth new races. Magic exists in a constant state of hyperflux, birthing new powers and changing the functions of old ones.But none of that mattered for Rex. He wasn't a Drift Soldier-- as much as he wanted to be. He didn't have powers-- even if he wished he did, so when he graduated primary school, he expected to get his Drift Armament and find a bit of consistency for once in his life.But you know what they say about expectations......DING![Congratulations! You have awakened the Beast-Totem and unlocked your Werepanther System.][5 Totems Remaining....]*********Extra tags: kingdom building, military, martial arts, overpowered, scifi-fantasy, post-apocalyptic, factions,

Ban Yu-won can understand all the languages in existence. He was able to translate every language, modify it.

As a child, when Ban Yu-won first learned about the existence of the fictional building called the Tower of Babel in the Bible, his respectable grandfather told him it was their ancestors who built it.

“The Tower of Babel was completed without collapse, and people have the wrong idea.”

One day, out of the blue, the Union Academy practical exam began. Finding traces of his ancestors at the academy, Ban Yu-won decides to enroll in the academy full of monsters.

Humans across the world ended up joining a “Demon Kings and Heroes game”.

Several billion people were set down upon another world to act as “Demon Kings” and “Heroes”. Everyone has to chose their starting races from the start.

Zhang Nu was set in the Demon King camp.

He discovered that he could see hidden information that no one else could.
