The waistcoat jumps sideways, please Ke Xue stay away from me!

After Qingzhu Youyang chased him out just now, Fangtani Rei, who was holding a flashlight, was about to catch up with Qingzhu Youyang when he saw him running away quickly.

It seemed even scarier to chase people with a flashlight while leaving the light of the bomb for Matsuda Jinpei to defuse, so Rei Fukiya stayed next to Matsuda Jinpei to illuminate him.

The first bomb has just been defused and now comes the second bomb.

The structure of the second one was somewhat different from the first one. Matsuda Jinpei quickly analyzed the structure and continued to dismantle it one by one.

Without protective clothing or other safeguards, the two teenagers braved the cold underground and faced dangers that might happen at any time.

Although it is not so cold that the breath condenses, it does affect the speed of the hand.

Jianggu Ling was a little anxious, and now he could only hold the lamp aside. I just asked Matsuda Jinpei if he needed help, but it seems like he can't do anything now.

Rei Fangtani, who is used to taking the initiative, felt a little uncomfortable after his identity changed into someone else's protector, but he soon calmed down and did what he could.

While holding up the lamp he began to analyze and observe his surroundings.

This place is about two meters above the ground. A large number of bombs were planted under the dormitories of the police academy students in order to detonate them and cause casualties when all the police academy students returned to the dormitories.

Fangtani Rei kept holding the lamp and continued to look for something.

However, so many bombs are buffered by soil and their positions are deviated, which at best will cause collapse. The impact on the first floor may be greater, and the rest will have relatively enough time to save themselves or wait for rescue.

Why are they doing this... It's absolutely impossible to be benevolent and want to keep some people.

At this time, Matsuda Jinpei also completed defusing the second bomb. The third bomb was activated immediately, with a countdown of seven and a half minutes.

As Matsuda Jinpei keeps dismantling the same model, his proficiency and disassembly speed will increase. But the cold made the body sluggish, and the speed of defusing bombs did not increase.

It takes about two minutes to defuse this kind of bomb, but since each one has some new tricks, the time increases to about three minutes.

Matsuda Jinpei looked at the bomb that didn't give them any chance to breathe. He put his hands together to warm them up and continued to open them.

"The bomb was placed in such a cold place and it was not destroyed."

After hearing what Matsuda Jinpei said, Fangtani Rei's thoughts were drawn to the issue of temperature.

The best storage temperature for bombs is about 15c to 30c at room temperature, but it is significantly lower than this range here. The fact that the bomb was not damaged can only be said to be of good enough quality and produced recently, and the low temperature was definitely not used to preserve the bomb.

What exactly is cryogenics used to preserve?

Jiang Guliu began to constantly search for the source of the low temperature. At this time, anything could happen, so even if it couldn't be stopped, it must be found as soon as possible.

It doesn't seem that simple to not be the main force but to assist on the side.

……

After observing the bomb, Matsuda Jinpei was in no rush to defuse it.

What was taught in class before, including theory, was that the sooner the demolition was completed, the better. After all, later would lead to changes. But it may not be applicable to this situation. After all, if you continue to dismantle at full speed at this speed, the final outcome will only be death if the dismantling speed cannot keep up with the countdown.

The idea of ​​the person who made this kind of bomb is that after the police investigate the scene, in order to minimize the damage, only one person will be left at the scene to dismantle the bomb and another person to investigate.

In this way, the time is getting shorter and shorter in the end, and everyone will be buried here before it is too late.

If it were normal, both people could survive, but the time was getting shorter and shorter, and in the end there might only be a dozen or a few seconds left, and they wouldn't even have time to finish their last words.

There is also this special series connection method, which will not be able to make it in time if multiple bombs are activated at the same time.

Now the only way to have enough time to wait for rescue is to keep observing the bomb, and then leave a few minutes to quickly defuse it.

At this time, there were four minutes left for the bomb, and Matsuda Jinpei started to dismantle it again.

It took two minutes to successfully defuse it. I quickly executed the steps that I had rehearsed several times in my mind, but then the two bombs lit up at the same time.

The countdown on both sides is five minutes.

Who came up with this fantastic idea?

It still has a slightly different structure than before. It will take at least a minute to re-observe and analyze it. The two minutes to defuse each bomb is too tight.

"zero."

Rei Fukiya, who was still looking for the source of the air-conditioning, was recalled by Matsuda Jinpei.

"What do you need me to do?"

Matsuda Jinpei roughly divided the tools at hand into two categories and separated some from each.

He handed part of it to Fang Gu Ling and motioned for him to look over there.

The two red lights flashed almost simultaneously, and the numbers on them continued to decrease.

"I don't have enough time to dismantle two of them at the same time. You and I need to dismantle them at the same time. Remember the structure of the bomb at the beginning, right? Find out the differences and tell me."

The original box bomb structures in the class are the basic versions of these. Although the dismantling process is the same, the extra wires must be avoided.

After saying that, the two of them began to observe the bomb in front of them. Fortunately, the flashlight's illumination range was large and bright enough.

Matsuda Jinpei quickly found a different place, and then looked towards Rei Fukiya.

Fangtani Rei, who could only turn around and check with one hand, was a step slower, but he found it.

Due to time constraints, the two started demolition at the same time after confirmation.

The previous steps were still the same. Matsuda Jinpei completed it within three minutes after distinguishing the different lines. Rei Furitani, who struggled to defuse the bomb with one hand, was once again stuck on the original steps.

It's still the same point, but several lines are entangled together at the same time and cannot be separated for a while.

Matsuda Jinpei frowned and carefully removed the thread, until only two threads remained.

Which one is connected to the detonator...

"Cut the top?"

After judgment, Rei Fukiya came to a conclusion that was exactly the same as the last step in the demolition of the Matsuda Formation.

However, when Rei Fukiya was about to cut it off, Matsuda Jinpei stopped him, and then cut the lower thread using the light.

The bomb stopped in less than half a minute. The two wires of the bomb had their positions exchanged before protruding from the hole, and the degree of distortion after being frozen was even more outrageous.

But the structure of this bomb is still different from the previous one. Why are they activated at the same time?

The next bomb is still activated, with a three-minute countdown.

At this time, there were some slight noises coming from the entrance of the cave. Zero Fukiya raised his head warily, while Matsuda Jinpei tried to quickly eliminate the bomb.

Aotake Matayo and Midorikawa Matayo rushed back in time. They breathed a sigh of relief when they saw that they were still alive, and immediately came down to the location of the bomb.
