When natural disasters strike, mutant creatures run rampant across the post-apocalyptic world. Only those who awaken supernatural abilities can enter the safe zones. Zhuang Mo, an overworked architectural designer who died from exhaustion, finds himself reincarnated as an orphan living among the ruins. His affinity for wood-based abilities is off the charts, yet he is classified as the lowest rank simply because he can only control paper. Facing ridicule and persecution, Zhuang Mo discovers that paper is far from useless. Combining his knowledge of structural mechanics from his previous life, he folds paper airplanes sharp as blades, capable of piercing the tough hides of mutated beasts. During an airship accident, Sun Kang deliberately attracts a flock of mutant birds. Just as all the awakened fighters are powerless to turn the situation around, Zhuang Mo controls hundreds of paper airplanes, forming a deadly rain of blades that tears straight through the flock. He proves his strength with one declaration: 'Paper isn't weak. You just don't know how to use it.'
