Public Enemy of the Entire Server: I Conquered Online Games with Negative Attack Power

I’m Chen An, an air-conditioning repairman in real life, but in the game I have the hidden class [Ancient Climate Regulator]. The System says I’m “compassionate” and gives me a ridiculous trait: Attack -1. In other words, when I hit monsters, I heal them. I beat the Boar King until its health bar overflowed, and it just stood there questioning its existence. But that’s fine. My specialty is repairs. The NPC’s furnace is broken? I’ll fix it! Then I slap on an invoice: “5 silver coins, 10% daily interest. Don’t pay, and the furnace blows tomorrow.” The guild war is raging? I install central air conditioning on the battlefield, adjust the temperature however I like, and sell tickets to watch the show. A national war begins, and foreign players mock Chinese players for relying on sheer numbers? I smile and turn on “Quantum AC” across the entire battlefield. “Too hot? Too cold? Your bodies are under my control now.” Later, I found the weirdest guild on the server: [Princeling Party]. Other guilds hand out paychecks. We collect party dues. Other guilds compete for combat strength. We hold democratic meetings and practice criticism and self-criticism: “Your AC repair efficiency has dropped this week!” When every guild on the server joins forces to attack us, I activate the ultimate defense: [Global Warming Mode]. Under the blazing sun, the enemy guild leader sends a message asking for peace: “Master An, can you turn the AC up? We’re about to get heatstroke...” “Air-conditioning repair can change the world.” “And my wrench fixes all kinds of trouble (meaning equipment and enemies).”
