What Should I Do If My Cat Becomes a Devil?

The civet cat, which had been missing for a year, suddenly appeared on the window sill, skinny with only bones left. I carried it into the house and fed it canned food. I was so moved that I burst into tears. "I am the Demon King. You will become my servant and sign the soul contract." Contract reversal! The devil became my servant. It was so hateful that it squatted on the window sill and stared at me like I was looking at garbage every day. But when I say go east, it cannot go west. When I ask for takeout, it has to trot over with a takeout bag in its mouth. Until one day, my boss called me into a windowless conference room. The moment he turned around, his eyes turned green and his mouth was split to the base of his ears. "Kill you and the devil will die." He lunged at me. My cat squatted on my shoulder and yawned. "That's it?" ——Then I realized that the monster had invaded the entire office building. My colleagues, my boss, and even the lady at the convenience store downstairs may not be human anymore. And the devil I signed the contract with was squatting at my feet, waiting to see how I would die. "You're not going to help me, are you?" I asked it. It licked its paws and smiled. "It depends on your performance."
