Shu Hongzhen's face was pale and he sat on the bench on the side of the street with a little weakness, the violent impact and explosion just now made Shu Hongzhen who was sitting in the car quite shocked, and his heart couldn't stop beating until now.

The scene in front of him was a little chaotic, the powerful shock wave sent the Jinyi escort car flying, and now some of them were lying on the road, and the ground was full of debris from the explosion.

The explosion of the bomb caused the fuel tank to explode, and only the driver and co-pilot of the car were not directly affected by the shock wave of the explosion, and temporarily saved their lives and were taken to the hospital.

And the people behind the escort car were not so lucky, judging by the stumps scattered inside the car and the pieces of flesh stuck to the body of the car, all five escorts and Cohen died, and not even a single intact body could be found.

Although the fire in the escort car had long since stopped, wisps of black smoke still came out, and the scene was filled with smoke and a pungent smell.

The entire scene has been cordoned off by the brocade guards and police officers who arrived quickly.

"The lockdown has been extended to neighboring neighborhoods! Organize personnel to check the buildings on both sides. Quickly set up roadblocks with the scene as the center to intercept and screen criminals. A familiar voice came from the side, and Shu Hongzhen looked up.

It was Jing Daosheng who personally came to the scene to direct the situation, and Shu Hongzhen stood up.

Jing Daosheng also saw Shu Hongzhen sitting on the side of the road, strode forward, patted him on the shoulder and said, "Are you okay?" ”

Shu Hongzhen said depressedly: "I'm fine, but ......"

"Cohen is dead, I know. It's not your fault, it's my negligence, I didn't expect the enemy to be so arrogant. Jing Daosheng comforted.

"What's next?"

"The most important clue is interrupted, and we answer the starting point again. I can only continue to planing the square line. Jing Daosheng breathed a sigh of relief and said.

"Did you notice anything unusual on the way back?" Jing Daosheng turned around and asked.

"No, everything is normal, the explosion came very suddenly." Shu Hongzhen shook his head and said.

"I just looked at the explosion of the escort car, and it seems to have exploded from under the car. Could it have been that explosives were planted in the first place? Jing Daosheng pointed to the wreckage in the distance.

"Do you mean pre-departure? That shouldn't be possible, every time I get out of the car, I insist on it, and there are people watching when I stop and pull people on the way, and the possibility of being pressed with explosives is very small. Shu Hongzhen expressed his explanation.

"Then it's supposed to be a roadside bomb, but is that just the right thing to count as the escort car running over in the middle? can only wait for the preliminary identification of the scene to end. Jing Daosheng couldn't guess how the escort car was blasted.

The two rode back to the quarterback.

"The report of the Technical Investigation Section was sent, and it was preliminarily determined that the source of the explosion was the precision jet blasting of the chassis, which caused the explosion of the vehicle's fuel tank."

"Jet blasting...... Not an improvised explosive device. These grandchildren have a lot of tricks. Jing Daosheng touched his chin and said a foul word.

"Based on the environment of the explosion site and the body of the vehicle, it is very likely that the explosives were attached to the chassis of the escort vehicle in advance. Before the explosion, the chassis of the vehicle was opened by some kind of cutting device, and then the charge inside the explosive was shot into the compartment through the small hole that was opened. The moment this high-temperature metal jet was sprayed, there was no possibility of survival for the people in the car, and the second detonation of the fuel tank was only a function of annihilating the corpse. To sum up, the explosion was very technical, both in terms of the placement of explosives and the way in which people were killed. It can be said that the most sophisticated, but the most effective way to eliminate the target was taken. Shu Hongzhen explained in combination with the explosion simulation screen.

"Kill and bury ......" Jing Daosheng's teeth creaked, and he held the floss stick in his left hand.

"The method of explosion is determined, so how did this explosive be placed on the car?" Jing Daosheng asked.

"This ...... Forgive the incompetence of his subordinates, I really can't guess. Shu Hongzhen was stumped.

"Is it a rotary-wing drone again......"

"I don't think it's very possible, it's amazing to be able to carry and place such a complex explosive device under the nose of the vehicle-mounted millimeter-wave radar." Shu Hongzhen objected.

"I have a question, why do you assume that the explosives were attached to the car and then exploded, rather than exploding from the ground the moment the vehicle passed? What is your basis? Jing Daosheng once again raised the point of the accident.

"Because the road surface at the site of the explosion was almost undamaged, and no traces of the explosion were found. If it is shot into the chassis from the ground, there should be traces on the ground, not to mention that the escort vehicle not only has a military-grade millimeter-wave radar to detect airspace, but also a forward radar for auxiliary driving at every high-level, indicating that the explosives buried on the ground are almost the same as those on the ground. To sum up, if you want the explosives to escape the radar and leave no traces at the scene after the explosion, it is better to achieve a difference between the explosion point and the burial point. Shu Hongzhen explained his thoughts.

"In your opinion, the explosion was an explosive device similar to the principle of armor-piercing bullets, which first penetrated the chassis armor of the escort vehicle and killed and injured the occupants of the vehicle through a metal jet. And this explosive device was placed on the chassis of the car before it exploded, most likely on the road, right? Jing Daosheng summarized Shu Hongzhen's inference.

"I think so."

"Then let me ask you, how much do you estimate this explosive device to weigh?" Jing Daosheng asked.

"Not only can you cut the chassis by yourself without kinetic energy, but you can also have such a jet explosion...... It is conservatively estimated that there will be at least ten to twenty kilograms of ......," said this, Shu Hongzhen knew why Jing Daosheng asked so.

"Now that you know that this explosive device is not light, it was placed on the chassis on the road, and the vehicle itself cannot detect it?" Jing Daosheng proposed a loophole.

Shu Hongzhen didn't stop asking, the issue of how to realize the explosion of the escort car has once again reached an impasse.

This is a valid question, because high-end vehicles now have a tire pressure monitoring system, which means that all tires share the same air pressure, and the vehicle's intelligent program can automatically adjust according to the actual road surface or the condition of individual tires. This technology, which was first applied to wheeled armored vehicles in the past 20 years, has long been used in ordinary vehicles, and Jinyiwei's escort vehicle is no exception.

And this tire pressure system can completely push out the load of the vehicle according to the condition of the tire pressure, and the error is absolutely within one kilogram. So if, as Shu Hongzhen said, it is adsorbed on the chassis while the vehicle is moving, and the weight of twenty kilograms is definitely perceived by the vehicle's intelligent system.

"Call up the driving record of the escort car, let's check it carefully."

Shu Hongzhen called up the black box of the car that he took down after the accident. Fortunately, the data on the tire pressure of the car was not damaged.

The two of them gave priority to the tire pressure data and carefully proofread it paragraph by paragraph.

"Look at this paragraph, do you feel strange?" Jing Daosheng pointed to one of the tire pressure data on the screen and said.

The entire tire pressure data starts from getting on the car, except for some fluctuations caused by uneven road surface or cornering acceleration and deceleration, the tire pressure waveform basically maintains a straight line. Jing Daosheng pointed to this point as a relatively large fluctuation along the way, only to see that the tire pressure suddenly decreased, which means that the weight of the tire decreased, and then there was a sudden increase, which meant that the weight of the tire increased, and after a while, the tire pressure returned to stability. From the waveform display, the opening is not only larger than the waveform fluctuations in other places, but also the first sharp and then the slow, and the four tires at the same time first and then slowly, which is obviously unreasonable.

"There's clearly something wrong with this paragraph." Jing Daosheng came to a conclusion.

"Are you saying that this is the point in time when the explosive device was planted?" Shu Hongzhen asked.

"Very likely."

"Then this tire pressure shows why there is a return to the average, from the tire pressure point of view the vehicle has not increased the load." Shu Hongzhen raised doubts.

"Let's investigate the path of this fluctuation first." Jing Daosheng couldn't answer it for a while, so he could only choose to change the entry point.

Shu Hongzhen entered the location of the way and showed that it was a straight road, and the road surface was in good condition.

"Do you have an impression of this paragraph?" Jing Daosheng asked Shu Hongzhen, who was at the scene at the time.

"I don't have any impressions, it's normal all the way." Shu Hongzhen thought about it carefully and replied.

"It's really unclear what details you have while driving as a passenger, it seems that we need to ask the driver."

"Driver in front or driver in the back?"

"It's okay to ask the driver of the car in front, I heard that the driver of the car behind is still being treated after being bombed into the hospital, and his mental state is probably not very good."

The phone was called to the driver of the car in front of the convoy at the time.

"Hello chief. I'm the driver of the Fenwei 3 fast reaction team, what's the matter? The driver recognized Jing Daosheng and saluted and said.

Jing Daosheng went straight to the topic and asked: "Do you remember this part of the road that you passed when escorting "Gluttony"? ”

Gluttony was the code name of Operation Cohen at that time.

The driver looked at the spot that Jing Daosheng was pointing to.

"Impressions chief."

"What was unusual when you passed through here?"

"There's an anomaly." The driver replied dryly. Jing Shu and the two looked at each other after hearing this.

"When I turned into this street, I was driving in the inner lane according to the normal route of travel, but there was a road maintenance vehicle parked in the inner lane ahead of me, and I had to turn into the outside lane." The driver replied.

The driver's short two-word reply let Jing Shu and the others know that their previous reasoning was all correct. It is highly likely that the explosive device was planted at this one point!
