[Urban Fantasy] × [Workplace Comedy] × [No CP] The King of Hell is engaged in digital reform, and all employees in the underworld are required to take KPIs. If you are a scary ghost, you have to scan the code first, and if you are at the bottom of your performance, you are not allowed to reincarnate. Lin Xiaoyue, a programmer in the underworld who was about to die suddenly, was forced to become an external technical consultant to the underworld because of a "yin-yang eye bug" caused by overtime work. Her first project was to rescue Lu Beichen, the century-old antique ghost who couldn't even scan a QR code and was always at the bottom of the "scare department". From then on, she wrote code for human bosses during the day and "scary demand documents" and "warm service plans" for ghosts at night. Using big data to analyze "crippling" users and using project management thinking to conduct "supernatural pilots" almost turned the underworld workplace into a major Internet company. Just when she thought this was just an outrageous cross-border part-time job, a pocket watch from the Republic of China appeared, and a mysterious agency called "Qianyuan Division" came to her door and told her that the century-old case of her resentful colleague was closely related to some kind of "system collapse" that was happening in the underworld. Are they using KPIs to save each other's "careers", or are they unknowingly helping a certain mastermind step by step to update the entire underworld system and hit the final "Enter key"?
