I Don't Want to Be a Genius!

"Are you Heaven? That genius?" A very strange voice sounded like a metallic clang, but full of malice. "Who are you?" "Hahaha... I'm a genius too! I don't know which one of us is more genius?" His laughter was sharp and harsh, and in the quiet night it sounded like a knife scraping against the bones, which was unbearable. "What do you want to do?" My hair stood on end, and my confidence was obviously starting to run low. "Let's play a game. I'll give the question and you guess what I'm going to do." Who is this, so boring? "I'm not interested, you can find someone else." "You'll be interested. Now listen, you have a month to stop me. If you win, I won't show up again. If you lose, we'll keep playing. Now you go and open the door. I have a gift for you. I'll leave it outside the door. Enjoy your gift. I'll call you again." "Hey, hey..." The call was hung up. Suddenly all the sounds disappeared, and the room was so quiet that I could hear my heartbeat. I put down the receiver, climbed out of bed, walked to the door step by step, opened the door gently, and looked out. The corridor was quiet and there was no one. There was a one-foot-square cardboard box on the ground facing my door. I picked it up and weighed it. It was not too heavy. I carried the cardboard box into the house, opened it carefully, took a breath, and threw the cardboard box far away. A skull rolled out of it. Conception:
