Ghost World: I Can Spend Money to Upgrade

Coder Li Yi traveled through time. Traveling through time to a world of ghosts and monsters where everyone is in danger, where demons are in power and ghosts are rampant, becoming a useless soul-slayer who may be eaten by ghosts at any time. The good news is: I have an extra system in my head. A wild ghost knocking on the door? It's okay, spend money to upgrade the yellow talismans on doors and windows. A resentful ghost peeking? It's okay, spend money to strengthen the steel knife in your hand. The devil is asking for his life? It's okay, money comes and blood comes! Fill your body with energy and blood! Open the twelve orifices. Others kill their souls by working hard, but Li Yi kills his soul by spending money. When the whole bad land was still in danger, Li Yi was already sitting in the upgraded spiritual house, looking at the account balance, and calmly wiped the knife: "Anything that can be solved with money is nothing."
