Xie Yuzhe was investigating the scene, and Song Xin stood aside and watched, losing his previous enthusiasm. It's not that she's not interested in the police's case, it's just that she suddenly feels powerless, they're trying to find the murderer, but the murderer is much faster than them, and they can't catch a clue.

Judging from the situation in the house, someone has indeed visited. Xie Yuzhe asked the neighbors to inquire, and it was certain that the person who came to see Wang Chuan was Zhang Qi. It's just that they thought that Zhang Qi came over just to say something to Wang Chuan, but what they didn't expect was that Zhang Qi would do it, of course, they just guessed so.

Xie Yuzhe looked at Song Xin, he needed Song Xin's help now, but Song Xin's appearance was a little abnormal, and he asked with rare concern, "What's wrong with you?" ”

Song Xin shook her head in reply.

"Then ......" Xie Yuzhe didn't say it all, but he understood that Song Xin must know what he meant.

Now that he understands what Xie Yuzhe meant, Song Xin will not disappoint Xie Yuzhe.

After listening carefully, she said: "They talked about your coming over in the afternoon, Wang Chuan said that he would definitely not let you know the truth of the matter, and Zhang Qi thought that this matter would be leaked sooner or later, so he was leaving, and then there was the sound of Wang Chuan struggling. Strangling a person is indeed a good way, it is not easy to leave fingerprints, and it is difficult for the strangled person to make a voice for help, this Zhang Qi is really good at killing! ”

"Although I can't find out that there have been similar cases before, it can't be denied that Zhang Qi has done such a thing before, but what kind of method did he use to do it?"

"I don't know about this, so I can only wait until I catch him." The rare Song Xin didn't know how people were killed, and they didn't know the motive for killing. If Zhang Qi killed Wang Chuan in order to extinguish his mouth, the reason for killing other people is not clear, and it is also a yin trick such as pumping people's souls.

It's just that they are also guessing, and they are not sure whether those people were really killed by Zhang Qi, but the most suspicious person now is Zhang Qi.

"However, there is one thing I don't understand, Zhang Qida can kill Wang Chuan in the previous way, but why do you want to make such a big fuss, as if we are afraid that we don't know."

Xie Yuzhe also felt the same way, Zhang Qi was not the only suspect, if he continued to pretend that nothing happened, maybe no one would suspect him anymore, but he suddenly jumped out, it was really a bit not like a smart person's approach, and he would definitely not be such a stupid person.

Wave after wave, Xie Yuzhe sighed: "I really hope that there will be new clues, but it's not hopeless, I asked Yan Dan to compare the life circles of all the victims, maybe there will be new clues." ”

"Perhaps!"

At this time, Song Xin's mobile phone rang again, and it was still Jiangyang. They didn't see Jiang Yang as soon as they came, and Song Xin was still wondering, but he didn't expect him to call.

After answering the phone, Song Xin's tone was not good.

Hearing Song Xin's tone, Jiang Yang couldn't help it.

Knowing where Wang Chuan lived, Jiang Yang came directly, but he couldn't go upstairs directly, so he had to wander downstairs. He inadvertently saw a window open in Wang Chuan's house, so he went in through the window, but he didn't expect to see Wang Chuan's body as soon as he entered, and Zhang Qi had long been gone.

Despite this, he still wanted to find someone, so he left, so he was not at the scene when Song Xin and the others arrived.

Song Xin understood that Jiang Yang had also tried his best, so he didn't mean to blame him, but Zhang Qi disappeared, and he didn't know when he would appear again, and he wasn't sure if there would be the same case in the future.

Song Xin told Xie Yuzhe what Jiang Yang said, and Xie Yuzhe called the bureau and asked the bureau to issue a wanted notice.

"It's useless for us to stand here, go back, my men will stay here."

Song Xin nodded, there was indeed nothing they could take advantage of here.

When they went downstairs, Jiang Yang happened to come over, the three of them didn't say anything, they went their separate ways, Xie Yuzhe went back to the police station, and Song Xin and Jiang Yang went home.

After working for a long time and not getting anything done, and someone died, Song Xin felt a little tired, so she fell asleep on the seat.

Someone called out to herself in a daze, Song Xin tried to open her eyes, "What's wrong?" ”

"Your phone."

I don't know when the mobile phone fell out of Song Xin's coat and fell under the seat, Song Xin picked up the mobile phone in a daze, answered the phone, and Xie Yuzhe's loud voice came directly from the other end of the phone, and Song Xin suddenly didn't feel sleepy at all.

"Say what you say, say it again."

"Lu Feifei is missing!"

"I'll go over now!"

This is a very serious matter, and Xie Yuzhe, who is as calm as he is, is also excited.

Song Xin hurriedly asked Jiang Yang to turn around and go to the police station, although Song Xin convinced himself that Lu Feifei would be fine, but it was difficult to say if Lu Feifei's disappearance was related to Zhang Qi. Anything can happen against an unpredictable opponent.

When he arrived at the police station, Song Xin saw Xie Yuzhe sitting there with his head bowed at a glance, Xie Yuzhe's state was telling Song Xin that Xie Yuzhe was very angry now.

Xie Yuzhe's temper is very good, which is recognized by everyone, but this does not mean that he has no temper, once someone provokes him, his temper is very big.

At this time, Song Xin naturally wouldn't provoke Xie Yuzhe, she asked Yan Dan about the situation. After Yan Dan finished speaking, Song Xin already had seven or eight points to be sure that it was Zhang Qi who attacked Lu Feifei. He was really bold enough to dare to do something to the police.

Because there was no more information, Song Xin could only be silent, and she couldn't help at all at this time. Zhang Qi is nowhere to be found, and his motive for taking Lu Feifei is unknown, and now the only thing they can do seems to be to wait for Zhang Qi to hear the news, because Zhang Qi's ultimate goal must not be Lu Feifei.

It didn't take long for the phone in the reception room to ring, and Zhang He picked up the receiver.

Zhang He answered the phone, didn't say a word, and then said to Xie Yuzhe: "Captain, it's Zhang Qi who is looking for you!" ”

Xie Yuzhe tried hard to keep himself calm, and took the phone, "Zhang Qi, what do you want?" ”

"It's very simple, exchange Wu Ji for Lu Feifei."

Immediately, the phone hung up.

Seeing that Xie Yuzhe's demeanor was wrong, Song Xin asked, "What did he say?" ”

"He said he was going to exchange Wu Ji for Lu Feifei."

"Why did he exchange Wu Ji for this, he killed Wang Chuan, he should also want to kill Wu Ji, if he wants to kill Wu Ji in the same way as before, just wait until Wu Ji is acquitted."

"Anyway, Wu Ji must have something very important to him."

"That's true, but what is it?" No matter how you look at it, Song Xin doesn't think that Wu Ji is a person with deep thoughts, and it is estimated that he is the kind that is used as a gun.

"Just ask Wu Ji directly!" Xie Yuzhe can't wait any longer, he will never allow people like Zhang Qi to run rampant, Lu Feifei must be saved, and he can't let Zhang Qi succeed.

Song Xin hadn't seen Xie Yuzhe so impatient, so she hurriedly followed.

In the interrogation room, Xie Yuzhe grabbed Wu Ji's collar and said angrily: "Say, why did Zhang Qi save you?" ”

Wu Ji's eyes flashed for a moment, and then he said: "Why should I tell you, since he wants to save me, I advise you to agree to his request!" ”

Wu Ji's words sounded very proud, but Song Xin, who was standing on the side, obviously saw that Wu Ji had a moment of doubt, it seemed that he didn't know why Zhang Qi wanted to save him.

Wu Ji's words angered Xie Yuzhe even more, and Song Xin grabbed Xie Yuzhe before he got angry, "I have something to tell you!" Saying that, it doesn't matter if Xie Yuzhe wants to pull people out.

After getting outside, Xie Yuzhe asked, "What's the matter?" He really didn't understand why Song Xin would stop him at this time.

"I don't think Wu Ji himself knows why Zhang Qi wants to save him now."

This sentence calmed Xie Yuzhe down slightly, "Why do you think so?" ”

"I saw that his expression was a little unnatural, and it was clear that he didn't know what he was using himself to Zhang Qi, and we might be able to use that to catch Zhang Qi."

Xie Yuzhe looked at Wu Ji inside through the monitor, Wu Ji did not show the joy he should have, but was contemplating something, thinking carefully about what Song Xin said, he said, "What do you say." ”

"I went in and convinced him to help us."

"Does it work?"

"If it's useful or not, you have to give it a try, and besides, he's my client, and I'll be able to convince him more easily than you."

"Okay."

Song Xin asked Xie Yuzhe to stay outside and went in by himself.

Seeing that the person who came in was Song Xin, Wu Ji hurriedly changed his very pitiful expression and begged Song Xin to help him.

Song Xin sat down, smiled and said, "Since I'm here, I'm naturally here to help you." ”

These words seemed to be true, but Wu Ji was suspicious and didn't answer.

Song Xin didn't seem to notice his reaction, and said, "You're wondering why Zhang Qi wants to save you, right?" ”

Wu Ji didn't speak, but this was what Song Xin knew, she was just stating the facts.

"As far as I know, you and Zhang Qi don't actually have much intersection, you can only be regarded as a person who collects money to work, and you shouldn't have participated in Zhang Qi's various evil deeds, but why did he save you?" Song Xin pretended to be pondering, and Wu Ji panicked all of a sudden, but he still pretended that nothing had happened.

Seeing this, Song Xin continued: "Of course we can let you go, after all, you are not the murderer who killed five people, but if you are caught by Zhang Qi, we can't guarantee that he won't let you become a murderer, of course, there is another possibility, that is, you are the person he will kill next, if this is the case, you will only die if you go out." But if that were the case, we wouldn't have much to lose. At the end, Song Xin laughed, looking very happy.

As soon as Song Xin said this, Wu Ji's face turned very bad, and he said in a trembling voice: "Detective Song, you must help me!" ”

Song Xin felt funny in her heart, this trick was really tried and tested, but she still said calmly on her face: "What good can I do to help you?" ”

"Entrustment fee, have you forgotten that we signed the contract, and I can pay you a lot of money."

Seeing that Song Xin was unmoved, Wu Ji said again: "I can help you catch Zhang Qi." ”

Song Xin thought to herself that this kid's brain was turning quite fast, since he had said so, Song Xin and the others naturally wouldn't let him say empty words.

"I'll go discuss it with Captain Xie, you wait here."

With that, Song Xin went out.
