Lin Zhan, a retired soldier who was seriously injured, became the most inconspicuous security guard in the top shopping mall "Vientiane World" in order to make a living. Patrolling at work, taking medicine after get off work, life should be so peaceful. Until the spiritual energy revives, the world changes drastically, demons stalk, and supernatural powers awaken. And his "strongest security system" was also activated at the right time: the daily tasks were refreshed - "Expel the Nightmare Beast at the Mall Entrance", reward: "Basic Qi Refining Technique"; Monthly Outstanding Employee Award: Ancient Artifact Fragments. While all parties were fighting for the spiritual veins under the mall, Lin Zhan was seriously mediating the "stall dispute" between the milk tea shop and the rune weapon shop. He just wants to protect this job and the fireworks world behind him that he governs. Until one day, the doorbell of the temporary security booth in the underground garage rang, and a trembling dragon elder stood outside the door: "Hello, may I ask... Wanjie Property Management Center, are you reporting here?"
