Three hundred years after the advent of Lingxu, monsters and beasts are running rampant, the divine order is resurrected, and mankind has entered the era of high martial arts. Lin Yuan, a boy from the outer city, was diagnosed with Qi and blood exhaustion during the awakening test, rated F, and only had 72 hours left to live. On the verge of death, he awakens the unknown divine order "Swallow" and must continue his life through hunting and devouring. In order to survive and to save his sister who was contaminated by the divine order, he stepped into the wilderness and evolved from a low-level monster, swallowing blood, seizing the divine order, destroying ruins, and gradually uncovering the truth about the arrival of the gods. When the gods looked down at the world and regarded humans as nourishment for harvest, Lin Yuan embarked on the road of killing gods in his mortal body.
