Happy Ghost and I Play Tricks on Zombies

On the third day after the zombie outbreak, I stayed at home and was worrying about the last section of toilet paper. The moment the door was broken open, a voice came from above: "Brother, your toilet has been blocked for three days, right?" A green-haired ghost in a floral shirt was floating in the air, holding a lollipop in his mouth and raising his eyebrows at me. He said that if he wanted to be reincarnated, he would have to make a hundred zombies laugh until they fell asleep—— "Wait, why are you looking through my classmates' records from ten years ago?!"
