I Became a Popular Spirit of the Underworld

After dying from overwork, Lin Chen wakes up in the Underworld and accidentally binds to a Merit Reward System. The system tasks him with reversing the Underworld's 3 million merit debt within three months to allow him to be reborn as the richest man; otherwise, he will be cast into the Beast Path. Determined to become the richest man, Lin Chen diligently works as a reincarnation ghost official. However, he accidentally releases a lost soul, causing the Underworld's merit to decrease rapidly. When the system issues a new mission to recapture the soul for a reward of 1 million merits, Lin Chen eagerly volunteers to return to the human world. He fulfills the wishes of the lost soul, Jiang Dahai, brings him back, and eventually catches the attention of the King of Hell for his exceptional work ability.
