In his waking moments, he is the hunter, and as he returns to slumber, he becomes the hunted. Xu Yangyi is a morose youth, barely old enough to be called a man, with a dark, tumultuous past. In an age where the sciences and cultivation could be considered one in the same, yet still remain the highest of secrecies, he moves towards the apex, step by step. In a world of ever-advancing progress, the splendor caused by such advancement is hard to ignore on both sides of these different worlds—public and hidden. However, across the ages, mankind has always been plagued by it. They lurk in the shadows and make meals of humanity like fine dining. Across millennia, they have walked alongside mankind, always in conflict. But in the modern age, a new shining pact has emerged, but all that glitters is not gold. Beneath this gilding, rumbles a storm between both sides that has stirred for ages, threatening to consume the world—and Xu Yangyi caught in the middle of it.
