As soon as Han Xiao finished speaking, Xiao Gang, who was standing behind Zhang Mei, snorted coldly: "Principal Han, this is a map, it's not an ancient leather scroll. ”

Han Xiao's face suddenly changed when he heard Xiao Gang's words, and he said embarrassedly: "This... To be honest, I don't really know, I stumbled upon this thing in the antique street, and I was quite curious and bought it, but I didn't really have any research on it. ”

Just as Han Xiao's words fell, Chengnan suddenly saw two people in security uniforms hurriedly walking towards this side. When the two of them came to see Han Xiao, there were policemen around them and they were stunned for a moment, and one of the younger security guards glanced at Zhang Mei and Xiao Gang before whispering, "Principal Han, my brother died yesterday." ”

"What? Your brother is dead? Han Xiao was stunned for a moment and exclaimed, "What's the matter?" I heard yesterday that your brother is fine, why did he die suddenly? ”

Another security guard, who looked a little older on his face, shook his head and said, "I don't know, but when I was preparing to bring his brother's body back to the back mountain for burial with the sword soldier today, I asked the doctor, and the doctor said that the sword soldier was infected with the corpse and poisoned to death." ”

Han Xiao's eyelids jumped when he heard this, corpse poison is very familiar to people like them who rob tombs, usually they have to wear plastic gloves on their hands when turning over corpses, in order to prevent themselves from being infected by corpse poison, but how could Xu Jianjun be infected with corpse poison? In my impression, except for a few tombs that I inquired about a month ago and turned over a few corpses, I didn't seem to have touched a corpse in the process of digging the grave in the past week, and the corpse poison on Xu Jianjun's body should not have been infected when digging the grave.

"Murderer?" The first reaction in Han Xiao's mind was that the murderer had moved his hands and feet on the murder weapon. Thinking of this, Han Xiao looked at Zhang Mei and asked, "Officer Zhang, I don't know if you have heard about the death of our security guard Xu Jianbing here?" ”

Zhang Mei nodded and said, "I heard about it, I believe Team Liu also sent someone to inform you, right?" ”

Saying that, Zhang Mei glanced at Xu Jianbing and another security guard and said, "You are Xu Jianjun's younger brother?" Who are you? Why didn't I see you two when I recorded my confession the other day? ”

Seeing that Zhang Mei suddenly asked about the identity of the two, Han Xiao was also taken aback, in fact, both of them were also in school that day, but that day Xu Jianbing and Chen Xiong were sent by Han Xiao to dig a grave under the school, Han Xiao was afraid of Zhang Mei's suspicion and hurriedly explained: "Oh, this is Xu Jianjun's younger brother, this is Chen Xiong, both of them are security guards of this school, but they just took leave to go back to their hometown a few days ago, and this is not a sword soldier who hurried back when he heard that his brother had an accident." ”

Zhang Mei nodded and just glanced at Xu Jianbing roughly, and then put her eyes on the person named Chen Xiong, Zhang Mei once understood that this Xu Jianjun has such a younger brother, and the relationship between the two brothers is still very good, so Zhang Mei thinks that Xu Jianbing should not be the perpetrator.
