Metropolis: I Picked up a World of Cultivation

Li Changan, a senior high school student, accidentally saw an abandoned world of cultivation and activated a special negative emotion collection system. "Ding! The host can gain time to enter the abandoned world of cultivation by collecting the negative emotions of people around you." "Negative emotions?" Li Changan was a little surprised. I didn't expect that my system would have such a function. But how to collect negative emotions? "What the hell! Can the kid downstairs please be quiet? He won't be able to sleep at night!" At this time, a roar came from Li Changan's upstairs. The sound insulation of their building is not particularly good, so Li Changan just made a big noise downstairs, which obviously caused the displeasure of the people upstairs. "Ding! Zhou Xianqi's negative emotion value towards you increases by +15!" The machine sounds. This novel and its characters are purely fictitious.
