Entering a Shopping Mall, Will I Become a God?

Lu Shen was looking for a summer job in a shopping mall. Being drawn into a different world in a shopping mall, strange things happen frequently. A large number of shops were boarded up. In my impression, there are old stores that have closed down, and there are also stores that don't exist... The clerks are extremely enthusiastic and have fake smiles. He will encounter various monsters, as well as the sources behind those monsters, high-dimensional creatures! The more monsters he killed, the more miscellaneous entries were imprinted on him. Just as Lu Shen was fighting wits and courage with extraordinary monsters in this closed alien space mall. From what he has seen, the same type of terrifying monsters have caused huge disasters to human society in the outside world! Whenever Lu Shen kills a certain number of certain monsters in the mall. Monsters of the same type in the outside world will also be completely killed, and a mysterious weapon called "Artifact" will be unlocked. When Lu Shen left the mall with the artifact, he began to exude the aura of a strong man! "This is the world of humans, and I am the patron saint of humans. You are just a group of high-dimensional bugs. Why don't you get out!?"
