I Build an Office in the Fairy World and Manage It

The protagonist is a low-level civil servant who died suddenly due to overwork, but with a complete set of [modern administrative management systems], he traveled to the world of immortality where the jungle is strong. While all the monks are killing people, seizing treasures, and practicing hard in seclusion, the protagonist is thinking about how to register a household registration, issue ID cards, collect spiritual stone tax, and establish the first "street office" in the world of immortal cultivation for this group of lawless crazy immortals.
