On My First Day as a Substitute in the Underworld, I Directly Blackmailed the Saint

Fengdu took over the underworld, but faced a mess? If you want people, there will be no one, if you want things, there will be nothing! Fengdu looked at the mess in front of him and suddenly understood why Houtu wanted to go into seclusion! But Fengdu is a time traveler with modern ideas! He directly brought modern thinking into prehistoric times! The KPI assessment made everyone in the underworld go numb instantly! If the reincarnation process is further optimized, no one who wants to join the team will be able to do so! Even if Nuwa wants to jump in line to see Fengdu, she has to make an appointment according to the process! Sanqing is dissatisfied and wants to cause trouble? Underworld security teaches them how to behave! Is God unfair? Then it's up to Fengdu to create a fair tunnel!
