"Beep beep!"
Tianlang called Lin Chen.
"Tianlang, any news?"
Lin Chen answered the phone and asked.
On the other end of the phone, Tianlang said helplessly, "Not yet. Mr. Lin, we have received those three thousand drones, and we have an idea now. Please help us see if this idea is feasible."
Lin Chen's heart stirred.
"You want to use those three thousand drones to monitor the whole city?"
Tianlang said, "Mr. Lin, yes. Many murderers in homicide cases will not leave immediately. The more anxious they are to leave, the higher the chance of being suspected."
"Some murderers even return to the vicinity of the crime scene."
"We have now basically determined that this case is not simple, it is very likely the work of professional agents."
"Can't your drone determine whether a person has received military training?"
Lin Chen considered for a while and said, "Tianlang, my drone does have such capabilities. But if the murderer doesn't show up, there's no data, and it's useless."
"If the other party leaves by car, data cannot be collected."
Tianlang said, "Mr. Lin, our plan is to place them at bus stations, train stations, all large supermarkets, all residential area entrances, and main roads."
"We have set up checkpoints on the highways."
"We try our best to force the other party to take public transportation."
Lin Chen said, "If there are no other breakthroughs, you can try it."
Tianlang: "Mr. Lin, their systems haven't been updated yet."
"I'll help you update them now."
Lin Chen went to the study, and in about an hour, he remotely updated the systems of those three thousand drones.
The prison where Wu Haoyu was held was not in a mega-city; the population was only three or four million, and the entire city area was not particularly large.
Three thousand drones are enough to control key areas.
"Tianlang, it's done."
Lin Chen sent a message to Tianlang.
"Okay."
Tianlang quickly received the message.
Many excellent police officers are now here, and there are also many people from the National Security Agency here. Each of them took one or twenty drones and quickly left for the planned locations.
Time passed by, and drones were placed in position one by one.
They entered monitoring mode.
These drones didn't fly over, so they didn't consume power. The power they had was enough to last them a day.
In just over an hour, all the drones were deployed.
During this process, the drones discovered many targets.
"Beep beep!"
Tianlang called again.
"Mr. Lin, there's a problem."
"Many of our own people who have served in the military have been found. We'll provide you with a database. Can you let the drones remove the people in the database?"
Tianlang asked.
Lin Chen: "I do have a database, and I can remove them, but the murderer might be among them."
Tianlang said, "If the murderer is in there, then there's nothing we can do. There's just too much data for us to handle."
"Okay, give me the data."
"The drones will perform facial recognition to confirm identities. If they are in the database, they will no longer alert."
Lin Chen said.
"Okay, okay."
The new drone control system already has facial recognition capabilities. Matching the data is not a difficult task for Lin Chen.
He got it done in about half an hour.
Instantly, the number of alarms was greatly reduced.
"Phew!"
The National Security officer in charge of this area breathed a sigh of relief. If there were too many alarms, they wouldn't have enough manpower.
Excluding their own people, what's left are foreigners who have received military training. This city is not a particularly developed one, and there are few foreigners who travel here.
There are even fewer foreigners who have received military training.
In a residential area in the city.
A man in his thirties who looked ordinary was reading the news.
Wu Haoyu's case has attracted a large number of police elites. There are police checks on the highways and even ordinary roads leading out of the city. The traffic jams have caused some people to complain.
"It's getting more and more dangerous to stay with so many police officers."
The man thought to himself.
He killed Wu Haoyu.
He had arrived here two months ago. He didn't stay in a hotel, but rented a house here.
After the success, he did not flee immediately, otherwise, it would be easy to be suspected.
He originally thought of continuing to live for half a month before leaving, but he felt the pressure as more and more police officers arrived.
Hua country attaches great importance to this case.
"Let's take the train away tomorrow morning."
The man thought to himself.
He has a legal identity in Hua country. Soon he bought a train ticket to a city he had visited several times in the past two months.
And he also knew a girl in that city.
The night passed.
The three thousand drones later had some discoveries, and the people discovered were temporarily taken away by the National Security Agency one by one.
Some of them are spies!
As before, the man left with a bag on his back.
He walked out of the residential area to take a taxi.
There was a drone hidden outside the residential area where he lived.
"Beep beep!"
The man's walking posture was different from ordinary people's. Soon the drone warned, and the information was transmitted to the command center as soon as possible.
"Immediately find out his information."
"Find out his past whereabouts."
Tianlang, who had arrived here, said in a deep voice.
He temporarily took over the command work of the National Security Agency here.
"Yes."
Soon the man's information was found out.
"Wolf Team, his name is Xu Ke. He only arrived in L city two months ago. He has five records of going to D city in these two months."
"He is a Hua country person, but he lives in Dongying all year round."
Someone reported.
Tianlang's eyes narrowed slightly.
Dongying Country?
He remembered what Lin Chen said, potassium cyanide appears a lot in Conan, and Conan is a Dongying country anime.
"Wolf Team, arrest him?"
Someone asked.
Tianlang: "Don't worry, the taxi driver is in danger if we act now. Wait for the drone to receive more data and confirm that he has 100% received military training before we act."
The drone outside the residential area didn't receive much data.
The current data matching degree is only in the fifties percent.
"Okay."
More than half an hour later, the taxi arrived at the train station smoothly.
There are several drones at the train station.
They recorded Xu Ke's walking posture from different angles.
The data matching degree continues to increase.
"Beep, beep!"
The system judged that Xu Ke had 100% received strict military training.
--If it is just simple military training, the walking posture may be the same as ordinary people in a year or two.
But people who have received strict military training are different, some movements and habits have formed muscle memory.
"Don't worry."
"Wait for him to pass the security check first, and make sure he doesn't have any weapons on him."
Tianlang gave the order.
Xu Ke passed the security check very smoothly.
Just when he thought he could leave smoothly, three plainclothes National Security personnel approached him. Xu Ke's pupils shrank. When did he get exposed?
"Xu Ke, right?"
"Please come with us."
One of the National Security officers took out his police ID and said.
The other two surrounded him vaguely.
Xu Ke's combat effectiveness is good, but he feels that in a one-on-three situation, he may not be a match for these three people.
And he is now at the train station.
If there is a fight, the nearby police will come to support him soon.
"May I ask what I have done wrong?"
"I'm going to D city to see my girlfriend, and my train is about to leave."
Xu Ke frowned.
"Please cooperate."
The head of the National Security said in a deep voice.
Soon the three of them took Xu Ke away.
