At this time, people knew why Qin Jinsong was in such a hurry. Even if the Xu family has great power, it will not be so easy to solve if people die. Moreover, Xu Tiantian's account of what happened at that time is very vague, and even has been trying to hide it. In desperation, the police had to take Xu Tiantian back for investigation.

After listening to Qin Jinsong's story, long Xingyun was silent for a while before slowly saying: "It's reasonable to say that if a person wants to kill, no matter how he kills, he will always have his own motive. It's unreasonable to say that Xu Tiantian killed because he was entangled by the other party too quickly, which can't constitute a powerful motive. With the power of the Xu family, Wu Dongdong can't have so many opportunities to entangle Xu Tiantian all the time 。”

"Yes," Qin Jinsong nodded. "That's what I said at that time, so the police just took Tiantian back as a suspect. But after all, it's not a matter, especially Tiantian doesn't say what she did at that time."

"It's a little difficult," long Xingyun said slowly after lighting a cigarette and taking a sip. "Now the main problem is what Xu Tiantian did when she went out. What's more, when did Wu Dongdong eat the poison in his stomach, and who did he meet during the time he ate it." Suddenly, long Xingyun looked up and said to Qin Jinsong, "this matter has been regarded as a major criminal case. If not expected, the case should be transferred to the Criminal Police Brigade. I'll call Xin'er first and ask how the situation is now."

When long Xingyun got through, he asked Tang Xin, "how is Xu Tiantian now? Did you find out what she did during her time out?"

Tang Xin also knows the relationship between long Xingyun, Qin Jinsong and Xu Tiantian. Therefore, he didn't hide much about this matter. In addition, she also knows that long Xingyun also has unique opinions on such things. Maybe he can see the truth. Then, she told long Xingyun the latest situation. From Tang Xin, long Xingyun was very happy Yes, Xu Tiantian didn't reveal anything after she was taken to the Public Security Bureau and transferred to the criminal police brigade for interrogation. However, she looked a little anxious and kept looking at the closed door, as if she was expecting something.

Don't say anything, be anxious and expect. This is Xu Tiantian's current state, and long Xingyun probably analyzed some things from these things. Xu Tiantian didn't say it, maybe she got an express hint from someone, and what she expected should be the emergence of someone who can save her. As for her anxiety, she should be waiting too hastily. And according to all the information The situation shows that she should have someone who cares about what happened.

When long Xingyun told Qin Jinsong about his conjecture, Qin Jinsong thought it over carefully, then pulled long Xingyun aside and said softly, "don't you know, Xingyun, Tiantian has always liked you. If she cares about someone, it may be you."

"Me?" long Xingyun was puzzled. "I'm fine, in good health and spirit. She didn't say anything for me. What did she do last night? It's really reluctantly. Moreover, I didn't see her at the company last night."

Qin Jinsong was puzzled when he heard what long Xingyun said. Long Xingyun was right. Xu Tiantian would not worry about long Xingyun if she worried about it? Then what was she expecting? Was it long Xingyun? However, long Xingyun didn't come out last night. It can't be because Xu Tiantian didn't want to say anything because she saw what long Xingyun was doing?

After careful consideration, long Xingyun said slowly: "Jinsong, I'll see Xin'er. I need to see the body before I can make further judgment."

Qin Jinsong agrees with long Xingyun's decision. Moreover, only long Xingyun has the strength to save Xu Tiantian now. While talking, they hurried to the Criminal Police Brigade. As for Zhang Qing and others, although they don't think as much as long Xingyun, they can gather ideas and benefits after all. Therefore, they cleaned up one after another, hurried downstairs and sun FA drove to the Criminal Police Brigade Team.

After arriving at the Criminal Police Brigade, long Xingyun entered the morgue with the help of CAI Lifeng and Tang Xin. Before arriving at Wu Dongdong's body, long Xingyun put on a mask and gloves. After careful observation, long Xingyun slowly said: "It's right that he died of poisoning, but it shouldn't be the poison he ate. You see, there is a small pinhole in his creaking nest. If I'm not wrong, someone should have given him an injection in his creaking nest before he died of poisoning."

Hearing the words of long Xingyun, several people looked at the right creaking nest of the body. When they looked carefully, sure enough, a small red dot appeared there. If they didn't look carefully, they wouldn't notice it at all. Moreover, it's not surprising that a person has a red dot on his body. This is also a place that previous forensic doctors ignored when examining the body.

Knowing that the red dot injection was the cause of Wu Dongdong's death, Xu Tiantian's suspect identity was removed. It's easy to find out that Xu Tiantian was already in the dormitory when the poison was injected. Then, Xu Tiantian can't complete such a murder.

Long Xingyun's explanation also made everyone very confidant, and immediately released Xu Tiantian. However, for Xu Tiantian not to tell the police what she did during that time, the police also asked her to be on call to help solve the case. But anyway, Xu Tiantian is fine.

When Xu Tiantian heard that it was long Xingyun who checked the body, she found evidence that she didn't kill herself. For long Xingyun, her eyes only had love and gratitude. Although it's a great feeling to be looked at by a beautiful woman. However, long Xingyun always feels that Xu Tiantian has something he hasn't said. However, it is inconvenient for him to tell Xu Tiantian the truth. He can only rely on his own investigation.

Although Xu Tiantian didn't kill the man, it's hard to deny that Xu Tiantian and the dead may have drunk together before their death. Finally, under Tang Xin's investigation, a bar owner confirmed that Xu Tiantian met Wu Dongdong. However, they didn't order anything in the bar. After saying a few words, Xu Tiantian left. After Xu Tiantian left, Wu Dongdong ordered several cups of deep-water bombs. After drinking the wine, he got up and left.
