Chapter 546： 1 mouse found

Now that the plan has been determined, the next step is to implement it.

The Liancheng detective team has entered the highest emergency response state, and the publicity to the outside world is because of the pre-war drama held near the Ocean Peace Summit.

This reason is justified. After all, the Ocean Peace Summit is a large international conference, and the participants are high-level and have a relatively large influence. As the security party of this conference, the Liancheng Detective Team naturally attaches great importance to it.

The main venue of the meeting.

Early the next morning, Chen Yan was personally inspecting the security situation of the meeting.

Although Chen Yan has finalized the trapping plan, it is still uncertain whether it will be successful or not.

The 12 desperadoes armed with guns killed the mission target with the determination to die. The harm was too great.

Although Chen Yan analyzed that the other party was likely to attack the cleaning staff and conference service staff, the other party would definitely not kill a person swaggeringly and come in as an impostor.

The opponent must have a complete raid plan, and there is a high probability that there will be help from the internal response.

Although Wang Min reassured Zhang Yunhu and Chen Yan that he was worried about what happened, but who would have thought that something would happen?

Although Chen Yan didn't care if he was promoted or not, at least he couldn't delay other people's promotion.

This breakthrough is much more important than Chen Yan's detection of one or two or even a dozen murder cases.

Walking in the venue, Chen Yan had already activated the gene locks of smell, vision and hearing, and the information of everyone around him flashed in Chen Yan's mind.

Last night, Chen Yan did not rest but checked the information of all the participants.

1782 people!

There are 1,782 people in total including the participants and the guarantee staff for the meeting.

Chen Yan did nothing last night, but passed through the information of these 1782 people.

At this moment, the information of 1782 people in Chen Yan's mind seemed to be flickering like frozen pictures.

Cooperating with the visual gene lock, Chen Yan can find the basic information of each other in the shortest time for every information that passes by Chen Yan.

Fang Rui, male, 29 years old, from Tieshi, waiter at the main venue...

Li Hui, female, 37 years old, from Panshi, the cleaner of the main venue...

It can be said that Zhang Yunhu's security work in the early stage was very meticulous, and everyone's information was complete.

Moreover, corresponding background information collection and review have been carried out for service guarantee personnel.

For this reason, Zhang Yunhu specially prepared a security personnel qualification review team to ensure that there are no problems in every link.

Compared with those who normally participate in the meeting, the qualification review of the security personnel is actually not at all nonsensical.

It cannot be said that everyone is rooted and Miaohong, but everyone's background is clear, and their work history is clear.

Even most of them are people with experience in large-scale conference guarantee work, rich experience, strong ability, and quick hands and feet.

However, if the preliminary work is done well, it does not mean that there are no flaws at all.

If Chen Yan was the commander of the opponent's gang, he would definitely attack the cleaning staff and service staff.

Because before the meeting starts, only these people can enter the venue in advance and have access to all hidden areas.

So the question is, what method will the other party adopt?

Imposter directly?

It's possible, but not likely.

Because the entry and exit of the conference security personnel is also done by swiping their faces.

The accuracy of facial recognition is still very high. Unless the other party uses special disguise means, such as 3D printing mask, it is possible to fool the face recognition system.

What is the possibility other than an imposter?

In the venue, Chen Yan seemed to look around casually, but in fact he had already come into contact with all the staff.

The scents of the 12 gangsters have been marked by Chen Yan on the smuggling boat. As long as any one of them appears beside Chen Yan, no matter what his disguise is, he will be discovered by Chen Yan.

Because it is easy to change the appearance, but it is difficult to change the smell of a person!

In the main venue, there are a total of 32 people guaranteeing services, but Chen Yan didn't seem to find anything special after contacting him. Everyone is busy with their own affairs, and everything is in order.

Prepare for the meeting to be held today.

Because today is the window period for the final arrangement of the venue, and the final security inspection will be carried out tomorrow, and no one except the security personnel will be able to enter.

Therefore, if the other party wants to enter the venue in advance, today is also the final preparation window.

Chen Yan had been in contact with the people in the main venue, and he was sure that there was nothing abnormal.

These people definitely did not have any replacements from the other party, and there was no trace of contact with those 12 people.

Otherwise, there will be some smell of the other party left.

Half an hour later, Chen Yan scanned the surroundings again, preparing to leave the main venue and expand the inspection to the periphery.

There are 1,782 people, and Chen Yan has only contacted more than 100 people so far, and the work is still early.

Ding!

Just when Chen Yan was about to leave, there seemed to be a barely audible crisp sound in his ear.

Stopping in his tracks, Chen Yan listened calmly and carefully.

No!

No sound at all.

Is it because I didn't sleep yesterday, and I was so nervous this morning, that I had auditory hallucinations?

Shaking his head, Chen Yan took a step forward and was about to leave the main venue.

Ding!

Chen Yan retracted his right leg that had already stepped out of the conference hall door.

Turning around, Chen Yan scanned the conference hall sternly.

This conference hall is the absolute center of gravity during the Ocean Peace Summit.

Both the opening and closing ceremonies will be held here, and some big names will be speaking here.

It can be said that if the security and service work of this meeting is 100, 50 will be accounted for here.

It is the top priority of the whole meeting.

The opponent's target person will also appear here.

Therefore, this conference hall must be the focus of the group of desperadoes.

If they can do something in this conference hall, such as installing a bomb, their target person is likely to be killed directly.

Therefore, if Chen Yan is the commander of the opponent, then he must try to do something in this venue.

So, what was the ding ding in my ears just now?

Chen Yan, who had obtained a specialization in blasting skills, thought of a possibility!

Taking out his mobile phone, Chen Yan immediately called Zhang Yunhu: "Team Zhang, arrange for the EOD detectives to come over. There may be explosives at the main venue!"

After hanging up the phone, Chen Yan turned around and closed the door of the conference hall: "All personnel immediately stand where they are and are not allowed to move around at will."

"Master, Chaoyang, watch over everyone!"

For such an important matter this time, Chen Yan would naturally bring someone he trusted, and Liu Qingshan and Zhang Chaoyang were recruited early in the morning.

"Yes!"

Although the two of them didn't know what clues Chen Yan had found, they must have heard Chen Yan at this time.

Pulling out their pistols, the two were on full alert, commanding the detectives following behind to maintain order.

In view of the particularity of this incident, all the detectives involved were in a state of first-level combat readiness with real guns and live ammunition.

The service staff who were still busy just now suddenly saw this battle, and they were all frightened and overwhelmed.

"Everyone, don't panic. We are detectives. Please stand still and don't move. You must obey the command. Anyone who moves rashly will be regarded as a dangerous element!"

Chen Yan also took out his pistol and walked around while explaining to everyone.

The seemingly absent voice just now disappeared again, and Chen Yan was waiting for it to reappear.

Ding!

A minute later, the voice appeared again!

Chen Yan turned his head and pointed at the crystal chandelier above his head.

That's where the sound comes from!
