Do you think you can show off as much as you want with the system? Sorry, I have to give back all the pretense. Host of the Avenue Library System: "Master Wang Hao, please spare me. Ever since I offended you, all the books in my mind have disappeared. No one has asked me to be my disciple for more than half a year." Food system host: "Wang Hao, please forgive me. Originally, the food I cooked was addictive, but now the food I cook is tastier than Coptis chinensis, and the restaurant is almost going bankrupt." Negative emotion collection system host: "I repent. I used to practice by blaming others, but from now on I will never quarrel with others again." Wang Hao crossed his legs and said, "Why are you so anxious? I'll take care of you after I finish teaching the hosts of these systems such as the pretentious face-slapping system, Shenhao system, absolute option system, black technology system, leader system, redemption system, summoning system, Taoist system, King of Soldiers system..." A time traveler obtains system administrator rights and defeats all systems in a world where everyone has a system.
