I'm Delivering Food in the City, and I Kill Some Evil Spirits by the Way.

Su Chong, a salted fish who just wants to lie down and deliver takeaways, earns his daily income from looking for cats. No one knows that he is the hidden ultimate trump card of the Lushan sect of Taoism, and he is also the young master of the top chaebol in Guangdong. Until in the shadow of the city, the omens of a century-old catastrophe quietly appeared, and demons and monsters began to gnaw at the ordinary world. Seeing the constant trouble coming to his door, Su Zhong sighed and took out a note from the takeout box. "Forget it, let's solve the source of the problem so as not to affect my order delivery." So, when evil cultists are brewing conspiracies in the haunted house, when ancient evil weapons quietly absorb the souls of strangers, when official organizations are helpless... They were horrified to find that the delivery boy who was riding a battery-powered bicycle with a sleepy look on his face was using origami as a soldier, forming an array with ordinary objects, and casually dismantling the huge situation in their eyes into pieces.
