In the old society era, due to human beings' wanton destruction of the natural environment, a large number of organisms became extinct and the biological chain was also destroyed. As a result, a series of mutations occurred in the world. A large number of creatures mutated and began to bite, gnaw, and evolve. Human beings were forced to flee to the safe zone——Royal City.
As the world mutated, humans also changed. They began to have special abilities. They found that these special abilities could help them kill strange beasts. We call these humans with special abilities unique ones. Those with unique abilities will have unique patterns on the backs of their hands - ribbing.
Purpose: Don't expect anyone to give you help in times of need. You should be grateful if no one rubs help in your face.
