The trace inspection is also working overtime, and the things sent by Lin Xi need to be analyzed in composition, which takes a lot of time, and when there is no clue and only relying on this one line, everyone in the Criminal Investigation Department can only wait, and it can be regarded as finally setting aside time for a supper.

Jin Moxuan was holding his fried noodles and eating them fragrantly, and Yang Peiman, who was on the other table, was no exception, and Lin Xi was the only one in the entire office who fell into contemplation.

Thinking back to today's content, that room is very illogical, but if it is determined that the five people have stayed, then no one can prove that they have heard the wind and left, which will make it even more troublesome.

In the end, it was Emand's reminder that he remembered to eat something.

Two hours later, the results of the test came out, and Lin Xi first received the electronic version of the test report.

Looking at the specific composition of the yellow substance in the last column, 89% is trinitrotoluene.

He rose from his seat at once, and the rest of the people came together.

Du Shuqing asked: "Trinitrotoluene......?

Lin Xi frowned and said, "Explosives." ”

Gao Jun suddenly realized: "Then we really found the right one?"

Lin Xi nodded: "Excluding the possibility of the existence of yellow gunpowder in ordinary people's homes, ninety-nine percent of them may be them, but the most critical problem is that we went to find people today, all of them are gone, and the scene is very clean, and even these yellow powders are found in the cracks." ”

"Their usual whereabouts are too hidden, right, even fleeing from here quietly?"

He took out his phone: "I'm going to report this to my superiors." ”

Lin Xi made four or five phone calls in a row, and Gao Jun communicated in their public security bureau, especially when it comes to this kind of big case, which requires the cooperation of many parties.

But since then, this matter has not gone very smoothly, and every highway intersection and entrance and exit port has all been issued wanted warrants, but these people are like evaporating from the world.

If they just wander around in T City, it will be fine, but if they leave T City or sneak out of the country, it will not be easy for them to do it.

Wei Chenwan originally stayed in the bureau with the mentality of wanting to help, but this time she really couldn't help, so she went to art class first on weekends.

At about three o'clock in the afternoon, when class was about to end, I suddenly received a call from Lin Xi.

And because she wasn't lecturing, she answered the phone: "Hey?"

"Don't get out of school yet, stay in the classroom and don't go out. As soon as the phone was connected, I heard Lin Xi's anxious voice.

"What's wrong?"

"Listen to me first, hurry up and tell the other teachers not to let the students go, we are daring here now. ”

"Is something wrong?"

"The surveillance swept five people, one of whom entered through the back door of your school, and was carrying a bag, and I was afraid he had a weapon. ”

"Then I'll go to the school station to broadcast. ”

"Don't broadcast, for fear of startling the snakes, we still have twenty minutes to arrive, and when we get there, we will evacuate the students quietly." ”

"Good. ”

After Wei Chenwan hung up the phone, she took two deep breaths on the spot to make her expression look normal, and then faced all the students in the classroom.

"Students, today the school is going to hold a mobilization meeting for the next training, so you can't leave school on time, it may take an hour, so tell your parents. ”

The students in the classroom were more obedient, and they began to take out their mobile phones to contact their parents when they heard the teacher say this.

"Don't make noise in the classroom, I'll talk to the other teachers. ”

Dou Yifei is not a loss because he was raised by Lin Xi since he was a child, if the mobilization meeting cannot be notified so temporarily, even the teachers rely on one person to pass the word, especially when Wei Chenwan received the phone just now, it sounded like something had happened, and after he finished the phone call with Wu Qianqian, he pinched his mobile phone and sent a message to Lin Xi.

It's just that Lin Xi didn't have time to pay attention to the message on his mobile phone at this moment, and just stepped on the accelerator under his feet hard.

How did you get mixed up in the city by this group of people?

Wei Chenwan notified the classrooms one by one, and explained the situation to the teachers in private, and the most important thing is that she must let the school management know.

In fact, the school's senior management was also called by the public security, so they reached an agreement with Wei Chenwan's opinion, and simply brought the mobilization meeting to today.

Every teacher was very nervous at the moment, because they had experienced the airport incident before, so they trusted Wei Chenwan very much.

The police in the neighborhood were all plainclothes and stayed near the school, and what they needed to confirm now was whether the person was still at the school, and if so, where he was.

Lin Xi needs to go to school.

He first called Wei Chenwan and asked them to get ready, and each criminal police officer applied for a gun for this operation.

Lin Xi put the pistol in her clothes, put on a baseball cap, and walked to the school under the attention of her colleagues, Wei Chenwan had already passed the gas with the security guards downstairs, Lin Xi walked directly to the floor where she was, and then knocked on the door of her classroom.

Wei Chenwan hurriedly walked out of the classroom after hearing this.

"Lin Xi. ”

"Don't be afraid, our people are out there. ”

"I'm not afraid. Wei Chenwan's little face replied with a serious face.

Lin Xi laughed: "My voice is shaking, and I don't want to say that I am afraid." Then he reached out and hugged Wei Chenwan.

Wei Chenwan wrapped her arms around his waist and touched a hard object behind his clothes.

"It's ......"

"We all applied for guns, just in case. ”

"And what's your plan now?"

"Find out the people. ”

Wei Chenwan took Lin Xi to the monitoring room in the school.

"You look here now, I'll go back to the classroom first. ”

"Okay, there is a situation to call us. ”

After school at four o'clock, the school did not let the students go, and began to inform the students of the intensive training course in two months through the radio, and every student was not forced to participate, mainly for the art students in January and the cultural examination in the second year.

Lin Xi stayed in the monitoring room for a long time, and connected all the monitoring in the school to Su Xiaopu, the monitoring in the school has a dead end, and it is impossible to find out his route completely from the moment the person enters the school, which is a headache.

And the monitoring order is very messy, and it is impossible to photograph the first floor in the stairwell, Lin Xi asked the staff in the monitoring room, and the staff's unfamiliarity with the business also brought Lin Xi a lot of trouble.

The man walked to the stairs of a certain floor, and then suddenly disappeared, and then he couldn't find anyone in each surveillance, Lin Xi talked to Su Xiaopu on the walkie-talkie while looking for it.

"There are too many dead ends, and you can't look for them with great fanfare. Su Xiaopu doesn't know how many times he has regressed this video, and the tablet in his hand is stained with his fingerprints.

"I just don't know what the man came here for. ”

It's not the first time Lin Xi has been here, as far as he knows, every classroom and corridor here is monitored, and other dead corners are not important, so where will he be?

Wei Chenwan sat in the classroom, she couldn't listen to anything on the radio, she just pinched her phone and stared nervously.

Lin Xi's phone was answered as soon as he called.

"How?"

"You don't have surveillance anywhere here. ”

"Huh?"

"There were dead spots at the school and he was not seen again at the exit. ”

Wei Chenwan fell into deep thought, because she has always been two-point and one-line, and generally only goes to the office to prepare for classes and then goes into the classroom to attend classes without exception.

"Rooftop!"

She suddenly remembered that there was still this place in the school's teaching building.

He turned the walkie-talkie back on.

"Be careful, the suspect may be on the school rooftop. ”

The policemen downstairs all heard Lin Xi's words on the walkie-talkie, but they couldn't see anything from their perspective on the rooftop of the building.

"Boss, do our people want to go in. ”

"Don't wait for the students in the school to withdraw under our noses, we can't let people get into the crowd, our people will take advantage of the students to get out of school. ”

The mobilization meeting on the radio was coming to an end, and Wei Chenwan became more and more nervous, hoping that everyone would be fine.

Because of Wei Chenwan's advice, each teacher took the students in his class downstairs, Lin Xi guarded the only way to go downstairs on the rooftop, and the police outside the school also began to act.

Wei Chenwan walked out with the students in her class, and Dou Yifei walked beside Wei Chenwan and asked in a whisper.

"Teacher Wei, is something wrong, is my brother here?"

"Shhhh ”

Dou Yifei nodded.

But at this moment, Lin Xi heard a voice above the staircase where he was standing, and he looked back to see that he happened to meet the person coming down from the rooftop.

"Damn. Lin Xi said secretly.

The man saw that something was wrong and continued to reflexively run to the rooftop, he originally wanted to run when there were many people, who knew that before he knew it, the area around the school would become like this.

Lin Xi took the walkie-talkie and shouted: "The suspect is found, he is ready to go to the rooftop." ”

The policemen who were mixed in the crowd rushed out at once and ran straight to the rooftop of the building.

When Wei Chenwan saw Jin Moxuan on this floor start running, she knew that Lin Xi must have found out, and she was even more worried now.

Dou Yifei said beside her: "Teacher Wei, don't worry, my brother is very powerful." ”

Comforted by his own students, Wei Chenwan also showed a smile: "Just go downstairs obediently, don't let me worry." ”

Just when Wei Chenwan sent them downstairs and was about to leave the school gate, she was relieved, and then ran directly upstairs, and the situation upstairs was not very good now.

The man reacted quickly, and when he got on the rooftop, he closed the door directly, and a steel rod was there, Lin Xi couldn't push it open, and the iron door of the rooftop was kicked by him.

". ”

He couldn't see the situation on the rooftop, so he didn't know what the suspect would do.

His walkie-talkie began to sizzle.

"Team Lin, the person on the rooftop should be called Wu Jiang, and we will send drones to reconnoiter now. ”

After a while, the sound of drones was heard, and the police outside the school immediately received the picture from upstairs and told Lin Xi about the situation above.

"Team Lin, he has a gun, be careful, don't break in yet. ”

The picture in the drone saw Wu Jiang take out a gun from his bag, originally pointing at the door on the rooftop, as if whoever came in would be shot.

It is very troublesome for the other party to have a gun, Lin Xi not only has to pay attention to safety, but also prevents the suspect from harming the masses.

"Evacuate the people around, the drone looks close to attract his attention, and I find a way to get in. ”

The drone has determined the situation on the rooftop, and there is no substantive use, so the person controlling the drone downstairs tried to get close to Wu Jiang and kept hovering above his head, and the police downstairs used the drone to shout at him.

The voice kept coming from the walkie-talkie, telling Lin Xi Wu Jiang's dynamics, and while he was not paying attention, Lin Xi picked the steel pipe off from the crack in the door.

Bang!

A voice that Wei Chenwan had never heard before, and it was also a voice that she knew what it was as soon as she heard it, and she heard such a sudden sound when she was halfway up the stairs.

After this sound, almost everyone paused.

Jin Moxuan, who ran to the rooftop, shouted: "Boss!"

The drone in the air fell on the rooftop like a kite off the string, and the gunshot was the sound of Wu Jiang shooting down the drone, Lin Xi opened the iron door and rolled to the right and then raised the gun at him.

"Don't move!"

The two of them raised their guns to look at each other, and Lin Xi regretted a little that he didn't wear a bulletproof vest.

Jin Moxuan also rushed up and stood next to Lin Xi.

Wei Chenwan also wanted to enter the rooftop, but was stopped by Gao Jun.

"Don't go in, it's dangerous. ”

Wei Chenwan could only stand behind and look at the rooftop, this was the first time she had seen this battle.

Lin Xi spoke first: "Wu Jiang, you need to be arrested and put down the weapon in your hand now for the crime of illegally manufacturing explosives and smuggling and trafficking drugs." ”

Wu Jiang didn't speak, he still stood and looked at the rows of policemen in front of him, and he didn't show a trace of nervousness.

"If you continue to resist law enforcement, there will be more serious consequences. ”

Lin Xi took a step forward, and Wu Jiang raised the gun in his hand and shot at the ground in front of Lin Xi, making a pit on the concrete floor.

Lin Xi sighed, the gun in this person's hand was suspected of being modified, and the distance between them and the two sides of the confrontation had not decreased, so it would be difficult to completely subdue and not cause casualties, and he still had a lot to say to interrogate this person.

Wei Chenwan was startled again when she heard the gunshots coming from the rooftop, fortunately, the movement inside was not very big, otherwise she was really afraid that something would happen.

Unable to kill him as a last resort, Lin Xi and Gao Jun exchanged glances, Gao Jun silently touched his baton, waiting for Lin Xi's order.

"Wu Jiang, I reiterate once again that we are now going to arrest you and put down the weapons in your hands. ”

Wu Jiang was unmoved, as if the few policemen standing in front of him were invisible.

Lin Xi took a step forward and made a preparatory move, Gao Jun said that it was too late to quickly throw the baton over, Wu Jiang was not slow to react, he dodged slightly, the baton smashed on his left shoulder and then bounced on his left cheek.

Maybe it was just a second, Lin Xi rushed forward and threw the person to the ground, and a random gunshot rang out directly into the sky.
