Never Bow Down as a Slave

Spiritual energy revives and everything mutates. A small sparrow has a wingspan of five meters, a poisonous snake is ten meters tall when it raises its head, and the ocean is completely occupied by mutant animals! They have even evolved intelligence. In the 14th year of the federal calendar, the human race was divided into literary and martial arts. Tempering the bones and refining the five internal organs, using fists to slay monsters as a weapon; nourishing the soul and tempering the spirit, drawing the talisman of slaying monsters as a text! This is a war in which the human race is at a disadvantage. It is in danger, and the race will be destroyed... However, people have picked up swords and guns and will never bow their heads and become slaves!
