Horror Descends: The Entire Nation Burns Trillions in Underworld Currency from the Start

[Horror descends] + [Planning ahead] + [Ruthless and decisive] Zhang Yuan is reborn three months before horror descends, and is delighted to discover that burning paper money for himself earns him ghost currency. He immediately reports this to the government and mobilizes the entire nation to burn ghost money! Aircraft production is halted. Missile production is halted. Everything is redirected to printing ghost money! Power plants stop burning coal and switch to ghost money! Students stop going to class, adults stop going to work, and everyone starts burning ghost money! For a time, all across the country, people are either printing ghost money or burning it! The whole world is dumbfounded: Has Yanhuang gone mad? Three months later, horror descends, and countless terrifying creatures run rampant. Only when Yanhuang produces tens of billions in ghost currency and recruits countless terrifying creatures to serve it does the rest of the world realize: Yanhuang hasn't gone mad. They're the ones who should be going mad!
