Wilderness Apocalypse

A cataclysm divided the world into two parts: the wilderness and the barbaric land. The wilderness is a place for human survival, and the barbaric land is a paradise for wild beasts. Five hundred years after the establishment of the wilderness, a young man named Jiuling walked out of the hellish dark night town. While pressing bullets into the magazine, he hummed the ballads written for him by his sister when he was young, and embarked on a journey amidst the call of the world.
