The apocalypse arrives without warning on a bright, sunny day. More than half of humanity, along with countless animals and plants, are transformed into man-eating monsters.
At the same time, killing any monster activates the apocalypse System and gives people the ability to level up by fighting monsters. The old order is completely destroyed. No matter who you were before the apocalypse, all that matters now is strength. Those with power can do whatever they want, while the weak can only become servants to the strong or food for monsters.
Wang Cheng, an ordinary college student, is betrayed by a friend and left crippled. Relying on his one-of-a-kind quest System, he seizes his friend's opportunities and obtains the supreme Soul Demon inheritance. He can split his soul and occupy other people's bodies, treating them like clothes. As long as his soul survives, he can change bodies as easily as changing clothes and take on countless forms.
In the apocalypse, survival is the greatest wish of all. But Wang Cheng's friends and enemies alike know that one man will never die, because you can never know how many outfits he has.
