I Unify the Underworld by Burning My Homework

The day before school started, I burned all my endless homework to my deceased grandfather. Unexpectedly, my grandpa would beat me up in my dream that night - "They are burning money, houses, and JK maids. Why don't you burn a stack of five-year college entrance examination and three-year simulations for me?" What's even more outrageous is that this pile of homework actually bypassed all inspections by the underworld. The grandfather and grandson seemed to have discovered a shocking bug in the underworld. From then on, I burned paper and made paper in the earthly world, and my grandfather opened a supermarket in the underworld. Others go to their graves to burn paper, but I go to their graves to burn AK47s, drones, and self-heating hotpots. As business grows, dangers also follow. The grandfather and grandson were forced into a desperate situation. Grandpa slammed the feather duster: "Grandson, burn a big one this time." This novel and its characters are purely fictitious.
