Sweep the Floor of Npcs and Take Actual Control of the Tower of All Realms

The blood moon comes, the Trial Tower of All Realms opens, and the battle for national destiny begins. Song Mojun is assigned as the lowest NPC - a cleaning lady who sweeps the floor, and can be bullied by everyone. His teammates died tragically and the copy was cruel, but he secretly held the highest authority and controlled ghosts like chess pieces. On the surface, he appears cowardly, but in fact, he restarts the dungeon, kills players, and seizes S-level black technology. Pretending to be a pig and eating a tiger, everyone breaks the defense, but the waterman is the one who tops the national sports rankings? Hiding my identity, I am at the peak of my criminal career. I set the rules. Life or death depends on my mood. When the world is shocked: The glass cleaner is the real copy master!
