"It was Xiaozhou's birthday. Xiaoxiao began to recount the death of Lingzi.

"In the evening, Lingzi and I bought birthday candles, Xiaozhou set up the bedroom, and then we waited for Xiao Yao, who went out to get the birthday cake, to come back. When Xiao Yao went downstairs to the dormitory, she sent us a text message telling us that she was back, but she didn't get back to the dormitory until ten minutes later. We asked her why she came up so late, Xiao Yao said that she had already reached the third floor, but at the corner of the stairwell she found that her shoelaces were open, she put down the cake to tie her shoes, who knew that after tying her shoes, she found that the cake was missing. She searched left and right in the stairwell, and even knocked on two bedrooms to ask if anyone inside had seen the cake. She said that she also found the situation very strange, and she remembered that she put down the cake before tying her shoelaces, and that no one passed by her. Finally, just as she was about to give up, she found the cake again where she had just tied her shoes. Xiao Yao grinned after speaking, and we didn't think much about it and started celebrating Xiaozhou's birthday. Something terrible happened when the birthday cake was opened. I lifted the lid of the birthday cake box, Xiao Yao went to turn off the lights, Xiao Zhou took out the knife that was ready to cut the cake, and Lingzi was responsible for lighting the candles. Just when the lights were turned off and Reiko lit the candles on the birthday cake, we suddenly noticed that Reiko's face showed a terrified expression, and her mouth began to whisper, and later we heard that she was reading a number: 21, and there was a red number in the center of the birthday cake: 21. Later, Xiao Yao said that when she took the cake, she looked carefully, and the middle of the cake was the daffodil we asked to add earlier instead of a number, although Xiao Zhou is indeed 21 years old this year, but we really didn't think to write this number on the cake. At that time, Lingzi's voice was getting louder and louder, and then he shouted wildly, and covered his eyes with his hands, as if he couldn't see the candle he had just lit. We were all stupefied, and we all gathered around Reiko to silence her, but who knew that she suddenly picked up the knife that cut the cake and stuck it in her neck. Neither of us reacted, and I was standing behind her, watching as the knife plunged through the left side of her neck, the tip of the knife coming through the other side, and the wound was still spurting blood. The three of us immediately dodged Reiko and kept our distance from her as much as possible, but Reiko did not fall down, but continued to use the knife to cut her neck in a circle until her head fell to the ground. Reiko's blood kept spraying on us in the drifting candlelight, and it felt like a hot shower that lasted for a few seconds, and we frantically shouted for help, but no one could take a step until the school guard smashed open the door of our dormitory. Xiaoxiao said this, as if she was prostration, her hair dripping with sweat, like a pool of dehydrated seaweed.
