At this time, everyone knew why Qin Jinsong was in such a hurry. Even if the Xu family is very powerful, if someone dies, it will not be so easy to solve. Moreover, Xu Tiantian was very vague about what she had done during that time, and even tried her best to hide it. In desperation, the police had to take Xu Tiantian back for investigation first.

After listening to Qin Jinsong's narration, Long Xingyun was silent for a while before he said slowly: "It stands to reason that if a person wants to kill someone, no matter what method he uses to kill someone, he will always have his own motive for killing. If Xu Tiantian killed because he was too anxious to be pestered by the other party, it is really a little unreasonable, and this cannot constitute a strong motive for killing at all. With the power of the Xu family, it is impossible for the person named Wu Dongdong to have so many opportunities to pester Xu Tiantian all the time. ”

"That's right," Qin Jinsong nodded, "I said the same at the time, so the police just took Tian Tian back as a suspect." However, this is not a matter after all, especially since Tian Tian didn't say what she did during that time. ”

"This is a bit difficult," Long Xingyun lit a cigarette casually, took a puff, and then said slowly, "The main question now is what Xu Tiantian did when he went out." Moreover, there is also the question of when did Wu Dongdong eat the poison in his stomach, and who did he meet with during the time he ate the poison. Suddenly, Long Xingyun raised his head and said to Qin Jinsong: "This matter is already a major criminal case, and if it is not surprising, the case should be transferred to the criminal police brigade." I'll give Xin'er a call first and ask how the situation is now. ”

When Long Xingyun's phone rang through, he asked Tang Xin: "How is Xu Tiantian doing now, have you found out what she was doing when she was out?" ”

Tang Xin also knew the relationship between Long Xingyun, Qin Jinsong and Xu Tiantian, so he didn't hide much in this matter. Moreover, she also knew that Long Xingyun also had a unique opinion on such a thing, and perhaps, he might be able to see the truth. Immediately, she told Long Xingyun about the latest situation. From Tang Xin, Long Xingyun learned that Xu Tiantian did not reveal anything after being taken to the Public Security Bureau and transferred to the Criminal Police Brigade for interrogation, but her expression was a little anxious, and she kept looking out of the closed door, as if she was expecting something.

Don't say anything, anxious, expectant. This is Xu Tiantian's current state, and Long Xingyun has probably analyzed some things from these things. The reason why Xu Tiantian didn't say it was because maybe she got an explicit hint from someone, and what she was looking forward to was the appearance of someone who could save her. As for her anxiety, she should have been waiting too quickly. And according to all the circumstances, she should have someone she cared about and something happened.

When Long Xingyun told Qin Jinsong about his conjecture, Qin Jinsong thought about it carefully before pulling Long Xingyun aside and said softly: "Xingyun, don't you know that Tiantian has always liked you." If there's anyone she cares about, it's probably you. ”

"Me?" Long Xingyun was a little confused, "I'm fine, I'm in good health, I'm in good spirits, she didn't say anything about what she did last night for me, it's really a bit reluctant." Besides, I didn't see her at all when I was in the company last night. ”

Hearing Long Xingyun say this, Qin Jinsong was a little puzzled. Long Xingyun is right, no matter how worried Xu Tiantian is, he won't worry about Long Xingyun, right? So, what was she expecting? Could it be Long Xingyun? However, Long Xingyun didn't come out last night, it couldn't be because Xu Tiantian didn't want to say anything when he saw Long Xingyun doing something, right?

After thinking about it carefully, Long Xingyun said slowly: "Jinsong, I'll go see Xin'er, that corpse, I need to take a look at it before I can make further judgments." ”

Regarding Long Xingyun's decision, Qin Jinsong agreed very much. Moreover, now only Long Xingyun has the strength to save Xu Tiantian. While talking, the two hurried to the criminal police brigade. As for Zhang Qing and the others, although they didn't think as much as Long Xingyun thought, they were able to brainstorm after all. Therefore, they cleaned up one after another, and hurriedly went downstairs, and Sun Fa drove to the criminal police brigade.

After Long Xingyun came to the criminal police brigade, with the help of Cai Lifeng and Tang Xin, he entered the morgue. Coming to Wu Dongdong's corpse, Long Xingyun put on a mask and gloves. After a careful observation, Long Xingyun said slowly: "It's right that he died of poisoning, but it shouldn't have been the poison he ate that caused death." You see, in his creaky socket, there is also a tiny pinhole. If I'm not mistaken, someone should have given him an injection in his squeaky socket that poisoned him to death. ”

Hearing Long Xingyun's words, several people looked at the right squeaky nest of the corpse. A closer look, and sure enough, a tiny red dot appeared there. If you don't look closely, you won't notice it at all. Moreover, it is not surprising that a person has red spots on his body, which is also an area that was overlooked by previous medical examiners when examining corpses.

Now that he knew that the red dot injection was the cause of Wu Dongdong's death, Xu Tiantian's identity as a suspect was lifted. It can be easily investigated, when the poison was injected in, Xu Tiantian was already in the dormitory. Then, it is impossible for Xu Tiantian to complete such a murder case.

Long Xingyun's explanation also made everyone extremely confidant, and immediately released Xu Tiantian. However, for Xu Tiantian not to tell the police what she did when she went out during that time, the police also asked her to be on call to help solve the case. However, no matter what, Xu Tiantian is fine.

When Xu Tiantian heard that it was Long Xingyun who checked the body and found evidence that she did not kill herself, she only had love and gratitude in her eyes for Long Xingyun. Although it is a very refreshing feeling to be looked at like this by a big beauty. However, Long Xingyun always felt that Xu Tiantian had something unsaid. However, it is inconvenient for him to go to * Xu Tiantian to tell the truth, so he can only rely on his own investigation.

Although the person was not killed by Xu Tiantian, it is difficult to deny that Xu Tiantian and the deceased may have drunk together before their death. In the end, under Tang Xin's multiple investigations, a bar owner confirmed that Xu Tiantian and Wu Dongdong had met. However, the two didn't order anything in the bar, and after a few words, Xu Tiantian left. And Wu Dongdong, after Xu Tiantian left, lit several glasses of depth charges, and after drinking the wine, he got up and left
