The end of the world suddenly comes, zombies run rampant, animals and plants mutate, and the order of human society collapses instantly. Qin Feng, a wage earner at the bottom of society, awakened the [Infinite Devouring System] on the line between life and death. This system not only allows him to strengthen himself and acquire supernatural powers by devouring the crystal cores of zombies and mutant beasts, but what is even more outrageous is that after meeting special conditions, he can swallow everything - including the opponent's superpowers, weapons, luck, and even interpersonal relationships and emotional bonds.
At the beginning of the story, Qin Feng had a fierce conflict with Su Muxue, the "iceberg goddess" who came from a military family and had an S-level combat power rating, in order to survive. In a desperate situation, Qin Feng took the risk to complete the system mission and launched Concept Devouring for the first time, swallowing up part of Su Muxue's "hostility" towards him and turning it into "curiosity". From then on, he started the path of falling in love with, killing and eventually fighting side by side with this mortal enemy.
Qin Feng used the powerful ability of the system to gradually form his own force "City of Dawn" from a lone wolf struggling to survive, gathering talents from all walks of life, and met the twin sisters Lin Wanqing who is proficient in pharmacy and Lin Wanyue who has powerful spiritual powers. He leads the team to establish order in the wasteland, fight against the zombie craze, the terrifying mutant beast king, and battle wits with other survivor bases with ulterior motives, evil supernatural organizations, and reborn cheaters. As he continued to devour, his strength became stronger and stronger, and he gradually uncovered the shocking secrets of the coming apocalypse. Finally, he faced the mastermind behind all this and launched the ultimate battle.
