"On the night of the accident," Mr. Zhang continued, "Mrs. Liu first sent the dead child to her room, and then she walked through the whole dormitory building by herself, and finally found a suspicious pool of blood outside the door of Li Tang's bedroom. Mrs. Liu called to open the door, and there were four frightened girls in the bedroom, and Mrs. Liu asked them what was the bloodstain at the door, and none of the four people could say. At this time, the girls who had just scattered and fled regrouped and rushed towards the door of Li Tang's bedroom from two directions, and finally Mrs. Liu further interrogated under the watchful eyes of everyone. This time, the three girls in the dormitory began to target Li Tang together, saying something very unfavorable to Li Tang. For example, a girl pointed out that one night a month ago, Li Tang had gone out alone, because she got up at night to go to the bathroom and saw Li Tang disappearing at the staircase. Another girl said that Li Tang has been nervous for a while recently, and the slightest noise in the bedroom will cause her to react greatly, once she just accidentally knocked down a plastic bottle, Li Tang lying on the bed suddenly turned over and sat up, and then looked around with a pale face, looking very scared. The words of these two people made everyone suspicious of Li Tang, but it didn't seem to have anything to do with the dead child, and it was the girl who spoke last to push Li Tang into the corner. I helped give birth to the child, and I watched as she slashed the child a few times before throwing it down the toilet. The girl began to cry after speaking, blaming herself and begging for forgiveness. I also couldn't help it, she said that if I didn't help her, she would let me die as miserably as the child, and the girl explained over and over again. When everyone turned their eyes to Li Tang, they found that she no longer seemed to pay attention to everything that was happening around her, she just sat stunned, staring out the window with her two eyes, as if she had acquiesced to everything. Mrs. Liu walked up to Li Cheng at that time, stretched out her hand and slapped Li Cheng a few times, Li Cheng sat motionless without any resistance. Later, the other three girls in the dormitory also came over, punched and kicked her, and began to tear Li Tang's clothes to throw her out the door. During the whole process, Li Tang still sat there woodenly, enduring it silently. In the end, Mrs. Liu took Li Cheng out of the dormitory by the neck, and the girls guarding the door began to spit on Li Tang, and the shameless abuse began to resound through the corridor, while countless fists and feet stretched out to Li Tang, leaving blue or black marks on her body and clothes. Li Cheng lowered his head, like a doll being pulled out of the crowd by Mrs. Liu. ”

"Is that child really born to Li Tang?" Xue Kaimo asked.

"Haha, do you believe it? Actually, all this is a trap, and the only purpose of this trap is to kill Li Tang. Old man Zhang said.

"Why?" Xue Kaimo asked.

"Because she knew something she shouldn't know. Old man Zhang said.

"What's the matter?" Xue Kaimo asked.

"I'll tell you. Old man Zhang stared at Xue Kaimo's eyes and said after a pause.
