The Underworld's KPIs Are Killing Me, and the King of Hell Begs Me to Stop Overworking

After overwork stopped my heart, I went to the Underworld and set its KPI targets soaring. This is a nonsensical, power-fantasy infinite-flow story about using modern wisdom to reform the ancient Underworld, rising from a low-ranking ghost official to the ruler of reincarnation across the universe. It has the gravitas of historical fiction and the thrills of transmigration fiction, the schemes of political dramas and the wild imagination of science fiction.
