After the deployment and adjustment, the investigation efficiency has been significantly improved.

With the efforts of more than 200 security police officers and auxiliary police officers from the branch office, the list of owners and renters was summarized to the on-site command center like snowflakes, and then reported to the search command center. Feng Jinhui immediately organized a research and judgment team, the security team and the verification team identified mainland people who might have a relationship with Gu Sicheng based on the situation and clues they had learned before. Section Chief Li of the Hong Kong and Macao Liaison Section was responsible for sending the list of Hong Kong people to the Hong Kong police, and the Hong Kong side was responsible for identifying them.

Time passed by minute by minute, but it was almost 3 a.m., but the progress was not much. Especially in Hong Kong, I don’t know if it was “too responsible” and that it needed to be repeatedly “considered”, or the police force was insufficient in the middle of the night, and a few hours passed and more than half of the list was not ruled out.

Gu Sicheng released the second drone yesterday afternoon, obviously for reconfirmation.

He has no time and dares not wait any longer.

If nothing unexpected happens, he will take action after dawn.

"Brother, how powerful is the one kilogram of explosives?" Guan Xingwei was a little anxious. He was worried about the criminal police and special police at home, and the new home he just bought last year. He walked around the conference room twice in the conference room and returned to his seat.

He is anxious!

Han Bo is more anxious than him!

But anxiety is useless, the only thing you can do now is wait.

However, he asked this question to the point. There is no ever-winning general in this world. When the search work is carried out, bad plans must be made.

For example, the criminal police who had been squatting in Nanshan District had already followed the order to take Du Qian and Yu Lin and were sending the two to the front-line command center. Once the situation could not be controlled, Du Qian and Yu Lin would come out to persuade him. For example, the criminal technical experts from the Technical Department of the Criminal Investigation Bureau are now repeatedly calculating the multiple explosives that a drone can carry, and calculate the property losses and even casualties that may be caused under various circumstances.

For example, the deputy detachment of the Fire Brigade of the Municipal Bureau, the deputy secretary of the Political and Legal Affairs Committee of the Nanshan District and a deputy district mayor were still "inspected" in the fire brigade and several hospitals around Wangang International in the middle of the night. Once the least desired result occurs, medical staff can be organized to rush to rescue in a timely manner.

"One kilogram of t-n-t explosion-drilling, in theory, can generate 4.2 million joules of energy. According to the calculation of 1 joule equal to 102 kg per meter, the energy released by one kilogram of t-n-t can move a kilogram object 420 kilometers, or move a 100 kg object 2 kilometers. Of course, this is an ideal state, that is, all energy is converted into kinetic energy."

"I'm not good at physics, brother, can I give an example?"

"Well, in fact, a 76mm high-explosive shell charge of about one kilogram, which can turn a small house on the second floor into broken rubble; a grenade charge of about 50 grams, and it does not survive within a range of 10 meters after explosion, which means that one kilogram is equivalent to 20 grenades explode at the same time."

So powerful!

Guan Xingwei was shocked and stared at Han Bo and wanted to speak but stopped.

"Fortunately, what he has in his hands is not t-n-t, or even civil explosives produced by regular manufacturers, but illegally fried ammonium-oil explosives. Judging from the same batch of explosives seized by his peers in your province, the power is far from being compared with high explosives like t-n-t or c4. But he has six kilograms in his hands, even if the power is not very large, it is enough to blow your house into ruins."

"The drone is that big, not to mention six kilograms, it is unlikely to hang three kilograms."

"Three kilograms are already scary."

Han Bo raised his head and said solemnly: "First of all, we cannot confirm whether he has a drone with larger size and engine power and stronger mounting capacity. I just checked online that there are larger size civilian drones abroad, which can be bought as long as you are willing to spend money, and there is not much difference between controlling large drones and small drones; secondly, with his cautious behavior, it is impossible to have no backup plan."

"If you can buy a large drone, it may not be transported in."

"It's strict enough to crack down on smuggling. After so many years, there are still 'big flying' on the sea, and the number of 'shuimen' on land has increased year by year. Some mainlanders and Hong Kongers have brought various smuggled items back and forth between the two places every day, and there are endless streams of smuggled items."

After this search, who dares to underestimate Gu Sicheng again?

In the past few days, various anti-reconnaissance methods have emerged one after another, which is dazzling, such as high IQ and high technical crimes that can be replaced.

Thinking that he could avoid the rounding up again and again, now he sneaked into the encirclement of the police set up a net of heaven and earth without knowing it. Even though he knew that he was hiding in that area but did not know the specific location, Guan Xingwei couldn't help but ask: "What alternative plan can he have?"

“I’m thinking too.”

Speaking of this, Han Bo suddenly stood up and stared at the map he had just hung last night. "If I were him, no matter whether there was a drone that could carry a bomb or not, I wouldn't have exploded it like this."

"He will 'evaluate' the power of the explosion like in the movie, and confirm whether he has 'cleared' the two targets of Xiaolei and you?"

“There is this possibility.”

Han Bo pointed to the map and said in an almost certain tone: "It is indeed unexpected to engage in drone attacks and high-tech, but no matter how cunning he is, he is an outsider after all. In fact, not only him, there are not many people who can truly use drone technology to carry out precise attacks. They need to undergo professional training, and such professional talents are rare in the army.

What can be confirmed now is that he cannot own a military drone, it is neither easy to buy, nor can he use it when he buys it; what can be confirmed is that no matter how many people have helped him intentionally or unintentionally in the early preparations, he should be one person when launching the attack, and perhaps there are no people who are connecting to it. In other words, he cannot control two drones at the same time."

Guan Xingwei reacted and subconsciously said: "The drone may be able to carry aerial camera equipment and bombs at the same time. He can hide in the distance to carry out an attack, but at the moment of the bomb explosion, he will become blind and don't know what will happen after the detonation."

"Once an explosion occurs, the scene will be in chaos. If I were him, I would consider scrambling in and confirming whether it was successful. If it was not successful and there was a chance, I could carry out a second attack, such as placing another bomb, running to a safe place to remotely detonate. Or simply use a gun to solve the problem and then abscondly."

"Ruan, he will make a fuss about the word "Ruan"!"

Guan Xingwei could not help but breathe: "If I were him, I would have placed a few more bombs in other places. The amount of medicine should not be large. It can be detonated remotely and create chaos. You should also leave a big one for yourself so that you can take hostages and escape when surrounded by a group of people."

"We also overlooked one thing: Long-range detonation of drones is relatively safe, but there are too many uncertainties. What should I do if the drone suddenly fails when it fails? What should I do if the lightning-controlled device fails? What should I do if the remote control device fails? It can be said that this seemingly safest attack method is actually the most unreliable. Who is Gu Sicheng? Will he make such a low-level mistake?"

The more Han Bo thought about it, the more he thought there was such a possibility. He didn't dare to delay for a moment. He picked up his mobile phone and called the command center again: "Old Feng, Gu Sicheng will not put the eggs in a basket. I am sure he has a backup plan, or a 'two-pronged' or even 'three-pronged' plan. To ensure that everything is foolproof, it is recommended that you organize your forces immediately and secretly search and explode within two kilometers of Wangang International without arousing Gu Sicheng's alertness. The action must be fast and must be completed before dawn!"

The Party Committee of the Bureau was able to allow Feng Jinhui, who had already retired to the second line, to replace Han Bo as the commander-in-chief of the search operation, and to temporarily lead so many deputy detachment leaders and become the person with the greatest actual power in the Shenzhen Municipal Bureau. It is not only because he has a comprehensive understanding of the case, but more because of his rich experience in organizing and directing the investigation of major cases.

"Even if he doesn't go to Xinhao Garden, he still has to find a way to escape and find ways to escape unscathed!" As soon as he mentioned "searching", Feng Jinhui heard Han Bo's implicit meaning and suddenly felt a chill on his back.

"So I think he will create chaos." Han Bo confirmed worriedly.

In addition to using bombs, how else can Gu Sicheng create chaos?

Thinking of this possibility, Feng Jinhui's head became bigger. He closed his eyes tightly, pinched his nose bridge hard, and analyzed: "Cities are not rural areas, especially in Luohu District, where there is a large flow of people and a dense population, and things cannot be thrown around. Otherwise, even if the urban management and sanitation system fail to notice, they will be turned over by beggars. In other words, it is impossible for him to extract bombs for a long time.

It is too late to put it in the night, but at night there are few people and cars, it is easy to be exposed. Moreover, we deploy so many police forces around Xinhao Garden. As long as he dares to show his head, even if he wears a ‘human skin mask’, it is difficult for our investigators to avoid being discovered. During the day, if he really wants to do this, it can only be implemented during the day or in the evening.”

"I think so too," Han Bo took over the conversation and said coldly: "It will not be able to create chaos when placed too far, and remote detonation is also a problem. If he really does this, the bomb will not be placed too far, and it will definitely be near Xinhao Garden."

"This scope is also very large, and the search operation is different from other operations..."

"The shopping mall will be checked before closing, and the hotel will be cleaned before closing. It is too difficult to place bombs in shops along the street, and throwing them in trash cans is the least safest. Not only is the sanitation union cleans up the garbage before dawn, and even if it is not cleaned, it will be thrown away by the rag pickers. A residential community like Xinhao International is a good place to install bombs, but if the building is high, it is not conducive to detonation."

“The sanitary dead corners around Xinhao Garden?”

"Search first. Don't the police dog team have a few small dog hunting dogs? You can let the police officers with dogs pretend to walk their dogs at night and search around Xinhao Garden."

There is not much time left, so you can't delay for a moment.
Chapter completed!
