Zhao Changben's death proved that he could not have committed suicide. The wound is in the left chest, directly penetrating the heart. The wound is very strange, and there are burns around it. It was a bit like a gunshot wound, but no cartridge case was found in the room, and there was no bullet in Zhao Changben's body. And rummaging through the room, he found nothing that could be used as a murder weapon, let alone a match with the wound. Even the Ministry of Public Security was shocked. More police were dispatched from Shanbei Province to Qingbo to control the scene of the hospital and the ghost hunting building, and even a special police officer directly led by the Ministry was sent to investigate the case. This special police officer is a master who has been strictly trained in martial arts. He belongs to the Ministry of Public Security, that is, the special service personnel of the Ministry of Public Security. He is only under the direct leadership of the minister. If it were not for this serious case, he would not have used such a level of special service. But the special service rushed to the ghost hunting building to examine the scene carefully, and could not judge how Zhao Changben's wound was caused, but he was sure that it was not a gunshot wound. And with his little experience, he can't find out how the perpetrator got in. Therefore, it is suspected that there is an inside thief. It turned out that the police officers in charge of Zhao Changben in the Shannan Provincial Public Security Department had all become suspects. But for a moment, it was impossible to judge who had done it. Fortunately, the police of Shanbei Province have arrived and taken over the work in an all-round way, and it is estimated that the thief can no longer play a role. The special agent carefully checked the scene of the building, but there was nothing valuable to find, so he asked people to send Zhao Changben's body to the morgue of the hospital first. The special agent also rushed to the First People's Hospital to investigate the scene and check the three bodies killed last night,Magnesium Oxide powder, hoping to find a trace. By this time, Li Yuhua had left the hospital and rushed to the ghost hunting building. The scene in the ghost hunting building was also controlled; the floor was sealed off. There was a seal on the door, and there were police in the hotel from Shanbei province. But because it has been carefully checked many times, even the special police of the Ministry of Public Security have come to check, and the body has been taken away, the management is not so strict. Li Yuhua sneaked into the hotel and quietly went up to the roof while people were not paying attention. Because the floor of the crime was the top floor, Li Yuhua wanted to go down from the roof, but after careful observation the windows of the whole top floor were closed tightly, and it was not easy to get in. But this matter is related to her father's revenge,
