Evil Era

Seven hundred years ago, Blue Star experienced a huge disaster. Blood rained all over the world for three days and three nights. Eighty percent of the human race became zombies, and animals turned into huge and extremely aggressive monsters. This disaster swept all countries. In the end, only the Dragon Kingdom persisted and stabilized its footing. Humanity has struggled to reproduce since then. Gradually, humans awakened the ability of the "destiny weapon" and began to resist. The powerful humans of the human race signed three chapters of the contract with the Demon Emperor, and humans have prospered since then.
