Stop! You've Ruined the Underworld!

When he wakes up. Lin Fei discovers that he has already met his end in the underworld. The protagonist dies from the start. How is he supposed to play this game? He suddenly discovers that his younger brother in the mortal world is incredibly skilled at burning paper offerings. Since that's the case, he might as well properly develop the underworld. Develop the underworld's tourism industry? Fine, have his brother burn a Disney, a KFC, and a Wanda Plaza. Boost the underworld's GDP and employment rate? Fine, have his brother burn several production lines and build a few large factories. Want to conquer cities and seize territory, becoming the underworld's local emperor? Fine, have his brother burn some AKs, rifles, and rocket launchers… Encounter a troublesome enemy? No problem. He still has a weapon of mass destruction: burn a nuclear bomb labeled with three words, “Little Boy”…
