This is an age of darkness and destruction, and an age of breathtaking splendor. This is a world of demons running rampant and bizarre wonders, a world where myths have entered reality. Modern people, people from ancient times, legendary powerhouses, and strange creatures from ancient myths have all appeared in the same place. Who will become the world's ruler?
Demons, ghosts, monsters, and spirits; celestial immortals, divine maidens, gods, and the underworld; or perhaps flashing blades and a world ravaged by war. People's lives are hectic and perilous, and often they only come to their senses when their lives are threatened. The arrival of zombies shattered people's peaceful lives, making them feel as if they were in hell. Every day, they faced the threat of death and the fear of becoming one of the undead. As people longed for the good old days, they had no idea that this was only the beginning. While they wandered in confusion, helpless and at others' mercy, some had already embarked on a new path. Unbeknownst to anyone, this global disaster had quietly taken on a different character, becoming an unusual contest.
