Jin Huidian withdrew his gaze from the screen with a solemn face, what made him so not a provocation from the murderer, but the 72-hour countdown!

If they do not make any progress within 72 hours, the two victims, who are currently in critical condition but not yet in danger of life, will be poisoned by the murderers.

Jin Huidian didn't think that the murderer was joking, and no one in the special investigation team knew the murderer's cruel methods.

The 72 hours that had begun to count down made Jin Huidian extremely urgent, he first exhaled a long breath to stabilize the agitation in his heart and organize his thoughts, and then picked up the phone and dialed several numbers in a row, and quickly gave some orders to the person on the other end of the phone.

The news from the team responsible for squatting around the carpenter's shop - the manned surveillance camera had already confirmed most of his conjectures, and just now, from the hunter team, there was an idea worth investigating, which coincided with the next task to be ordered to the frontline team.

It is very likely that the murderer behind the scenes had personally entered the "Muyan" store, so the surveillance camera facing the "Muyan" store was destroyed in advance.

The damaged camera may not have been able to capture the murderer, but it may have been able to find some clues from the footage recorded by other cameras in the vicinity.

Whether it was his personal conjecture or another idea provided by the hunter team to their special investigation team, they all converged at one point - the surveillance video of that street!

Those surveillance footage is crucial, and it hides clues about the murderer that the shopkeeper wants to convey to them!

Time was pressing, and Jin Huidian, who had just made a guess, did not discuss it with the rest of the special investigation team, and gave the task to the front-line working group according to his own ideas.

Immediately after that, he would convene a meeting of the task force to express his speculation and further discussion, and then he would admit that he would be punished for illegally assigning tasks to the frontline working group.

Now the top priority is to concentrate on finding clues to the murderer from those surveillance videos!

......

With the assistance of the artificial intelligence of the substation, the concentrated team members carried out the task of investigating the surveillance footage in a tense atmosphere.

In order to minimize the investigation time, the city guards of the 6th District divided the street surveillance footage of the two months before and after into three days (Jin Huidian originally wanted to retrieve at least the first three months' footage, but the storage limit of most privately installed surveillance equipment is only two months, and the video files before that have been automatically overwritten- There is no such situation in the street surveillance installed by the government, but there are only a few official surveillance equipment on that street, and it is not possible to film the situation of this street), and the surveillance video of two months is divided into 20 copies and handed over to different teams for viewing.

A few hours passed, a dozen hours passed, and a day passed...... The task of viewing the surveillance footage is still going on.

At the 33rd hour, a member of the team responsible for the surveillance footage from days 48 to 45 found a sign after repeated review.

With this discovery, he applied for access to the video footage of the three days before and after this period, and then with the assistance of other members of the team and artificial intelligence, he locked down a man with strange behavior - this man showed from the surveillance footage that the location he was going to was the "Muyan" carpenter shop, and then, the surveillance camera facing the "Muyan" store was vandalized.

The man, who only showed a back in the surveillance footage, was suspected of destroying the surveillance camera under the calculation of artificial intelligence.

As long as the artificial intelligence produces this reckoning result, then the man needs to investigate - the team members who found the suspicious man immediately reported the news to the special investigation team.

The special investigation team that received the news, under the command of Jin Huidian, quickly tracked down the man who only showed his back!

In preparation for such a swift move, Jin Huidian, through Chief of Justice, Zhang Qianling, obtained a special permit from the City Guard headquarters, which would give the officers in charge of the case the right to view the surveillance footage without Party B's permission.

With this privilege, the artificial intelligence of the Sixth District City Guard multi-threaded access to the monitoring equipment implicated in the back, and established the operation trajectory calculation of this back - among them, the artificial intelligence of the other sub-bureaus with spare computing space and the artificial intelligence of the City Guard headquarters also took out a part of the computing space to assist, otherwise the artificial intelligence of the Sixth District of the Sixth District would not have been able to complete this level of computing in a short time.

Along the trail's route, countless surveillance devices were accessed, and after a lot of budgeting, the AI of the Sixth Precinct found the latest and last image of the shadow in a roadside surveillance camera – two hours before the deadline for the day.

The special investigation team immediately decisively sent the independent house in the surveillance screen to the nearest action team!

Instructed by his superiors, Liu Liyuan, who was closest to the target location, rushed to the target place with his own team racing against time!

At the same time, the other side.

In response to the tracking ideas given by the hunter team, the artificial intelligence of the sixth sub-bureau, which was divided into two parts, with the assistance of artificial intelligence from other sub-bureaus, extracted the suspicious behavior of the owner of the carpenter shop of "Muyan" after walking out of the store at a certain time from the surveillance video of the previous two months.

In these footage, the shopkeeper is shown traveling along the same route to a location on more than one occasion, deliberately avoiding pedestrians and carrying a tightly wrapped bag.

After the artificial intelligence of the sixth sub-bureau analyzed this, it immediately retrieved the surrounding surveillance video, and found a vague location along the surveillance camera of the store owner's figure - this area is located in the surveillance corner, and the artificial intelligence of the sixth sub-bureau did not confirm where the store owner finally went with these suspected military food items.

The artificial intelligence of the Sixth Sub-Bureau took this area located in the blind spot of monitoring as the center, and at the same time retrieved the video of all the surrounding surveillance equipment, and fed back the news to the special investigation team as soon as possible.

At this time, there are 13 hours left before the 72-hour countdown given by the murderer.

......

A group of City Guards driving flying wheels at full speed suddenly flew over the bustling streets, and some pedestrians who had caught a glimpse of this scene subconsciously looked up at the direction of the City Guards, pretending to ponder whether something was going on in front of them.

Soon, though, they forgot about it.

The target is located within the jurisdiction of the City Guard Team of the Sixth District, so the special investigation team assigned Liu Liyuan's team, which is closest to the target area, to check it out.

Flying at full speed, Liu Liyuan's team quickly arrived at the target location.

When the corner of the target building appeared in his sight, Liu Liyuan raised his hand and signaled the team members behind him to slow down their flight:

"Slow down and use the surrounding buildings as cover to slowly approach the target building. ”

Several team members understood, and tacitly dispersed into several roads and slowly approached the target building.

Liu Liyuan drove the flying wheel and quietly came to the front of the target building, he looked up at the quiet two-story house, raised his hand and made a movement.

Several team members who had already approached the double-storey house from different directions immediately followed Liu Liyuan's actions and rushed into the house!

The doors were broken, the windows were smashed, and all kinds of heart-pounding noises spread along with the search actions of Liu Liyuan and others after they rushed into the house.

There were not many rooms in this building, and they were quickly opened one by one under the swift search action of Liu Liyuan and others—but there was no one inside.

"No one found!"

"It's the same on my side. ”

"No one!"

The reports of the team members came to Liu Liyuan's ears one after another, he frowned, and ordered: "Carefully check if there are any secret passages, dark floors, basements, and all kinds of places and furniture where people can be hidden!"

"Roger!"

After giving the team members the order to "check clearly", Liu Liyuan and other busy team members walked through several rooms with little space.

Suddenly, he stopped in a room and his eyes fell on a computer desk.

In his sight, a bottle of drink that had been unscrewed and drank a few sips stood quietly on the table, and the outer wall of the bottle was attached to the tiny droplets of water vapor in the air condensed when it was cold.

Liu Liyuan picked up the bottle of drink with a serious expression, it was still very cold, almost as if it had just been taken out of the refrigerator.

Holding the frozen drink, Liu Liyuan touched the shell of the computer host with his other hand...... And the residual temperature!

This is a sign that even if the owner of the house is gone, it will have just happened.

Liu Liyuan looked at the window that was tightly covered by the curtains, and suppressed the impulse in his heart.

Beyond the wall were buildings as far as the eye could see, the streets were distinct, and the pedestrians on the road could not be found by the back of a person who only appeared in the surveillance footage.

Therefore, I can only carefully search this room inside and out, report the situation to the top, and hand it over to the special investigation team to deal with.

Maybe they're lurking in this house for a while, waiting for a target who might just happen to be out to get back here - but that's unlikely.

......

Six hours after the target building was found and the team was sent to carry out the arrest operation, the city of the sixth district still has not obtained any clues about the suspect from the surveillance around the target building, and at this time, there are still 6 hours and 43 minutes left The 72-hour countdown given by the murderer will be cleared.

At this time, the murderer has not yet spoken.

No one knows that the "progress" package referred to by the killer does not include recent actions, and no one knows whether the killer will "break his word".

All eyes are now focused on the visible fourth victim livestream, and if the killer really wants to commit murder against the victims, they can only judge it through this livestream.

The tension that made the heart beat heavy lingered in everyone's hearts.

At this juncture, in response to the ideas given by the hunter team, the artificial intelligence of the sixth sub-bureau has made significant progress at this juncture - the identity information of the suspect suspected of being a murderer has been found!
