"Okay, I'll bring you the high-speed rail map, structural drawings, and optical experts!"

When Chief Yan heard that Hao Zhengyi had an idea, he immediately said excitedly.

Later, after hanging up the phone, in front of all the captains, he immediately called the Department of Physics of Ningshi University, and sent a helicopter to find a team of doctors who teach optics on the spot! And before the arrival of the doctoral team, the permission was opened, and the computer of Ningchuan University can be traveled to the east at any time!

I have to say that with the support of Daming's strong national strength and infrastructure, the team has been successfully assembled in just ten minutes! And connect with Hao Zhengyi on the high-speed rail video!

Of course, at this time, Hao Zhengyi was also invited to the business hall by the train conductor to avoid being affected by the rest of the passengers, so that he could concentrate on finding the bomb!

"Xiao Hao, I invited Professor Duguyue, a doctor of optical physics, for you, if you have any requirements, just mention it! They will fully cooperate! ”

"Good!"

Hao Zhengyi does not shirk, it is about the lives of more than 5,000 people in the Ming Dynasty, racing against time, not the time to be polite!

"Hao Zhukuai, what help do you need?"

Professor Duguyue is obviously also a resolute figure, and directly asked Hao Zhengyi for his request.

"I need you to give a model, with the angle of sunlight from now to noon, with the route of the train, the train is higher than 100 kilometers away, there will be those nodes that will not shine for a few seconds; If the speed is below 100 km/h, how many seconds will there be no sunlight? ”

"You mean, explosives are optical sensors?"

Professor Duguyue deserves to be a professor, Hao Zhengyi has just spoken, and he understands the truth!

"Yes, it's optical sensing! Oh, by the way, you can consider the longest distance from Lan City to Ning City, and calculate the time to pass through the tunnel...... The time when the explosives are located in the node that is not exposed to sunlight will definitely be above the time it takes to pass through the tunnel......"

Although Hao Zhengyi's words were fragmentary, they fully expressed his opinion.

Duguyue completely understood what Hao Zhengyi meant, and immediately contacted the supercomputer of Ningshi University and began to calculate!

With the help of a supercomputer and a whole team of professionals...... In just ten minutes, the other party has already taken out thirteen nodes!

"Hao Zhu, we've already figured it out! At 100 kilometers per hour, the time to pass through the longest tunnel is 15 seconds, and the whole train, in this time period, can not be exposed to the sun, 15-20 seconds, only these thirteen nodes! ”

"Among them, there are five nodes, which are inside the train!"

"Good!"

Hao Zhengyi was overjoyed, he actually didn't believe that the other party could install explosives outside the train, otherwise, the other party must have the identity of a train inspection and maintenance officer, and with Daming's strict review system of household registration, it would be too easy to expose...... So, inside the train, that's in line with his guesses.

"Send me the location immediately, and I'll rush over immediately!"

"Good!"

The other party immediately sent the three-dimensional map of the train and the five standard nodes to Hao Zhengyi's mobile phone...... After receiving the location, Hao Zhengyi didn't say a word, and went directly to the marked node location!

It didn't take long for him to reach the first node......

The first node is at the junction of Green Car and Car 1...... He took a closer look around, especially where the sunlight could shine in...... A moment later, sure enough, where the gate of his train was, he found a translucent plastic plate.

I have to say that this bandit is really idle, and he actually adjusted the color of the plastic board to be similar to the color of the surrounding walls, if it weren't for Hao Zhengyi's on-site survey skills, he might not be able to find out.

Now that you've found the plastic sheet...... If there is no wire, it must be a wireless connection...... And then consider the interference of countless mobile phone signals in the carriage......

Hao Zhengyi looked around, and in the next second, he suddenly opened the partition above the hot water, and sure enough, a palm-sized detonator with a timer attached to the wall panel appeared in front of him!

"The first explosive, found!"

"Great!"

On the other side of the phone, a burst of cheers erupted! In front of the conference table, Yan Xinhong slapped his palm on the table violently, and did a great job!

found the target, and the next dismantling of the explosives naturally did not need Hao Zhengyi...... The high-speed rail police immediately contacted the master of removing the explosives from the six doors of Daming, and carefully defused the bombs in the case of linking the video......

Hao Zhengyi took his mobile phone and rushed to the next explosives point......

In the place of the window of the second section, the second welt was found, and from under the seat, the second explosive was found...... The strong man sitting in the original position was so frightened that he was covered with cold sweat, he never expected that he was sitting on the explosives?

The third explosive, also found at the junction of the train......

However, after finding the second and third ones, no matter how Hao Zhengyi searched in the remaining two locations, he couldn't find the last one!

Seeing this, in an instant, the atmosphere of the entire train and even the office across the phone instantly froze......

"Xiao Hao, why don't you look for it again?"

Yan Xinhong was anxious, although his words were gentle, but from his expression, it could be seen that he was extremely nervous.

"It's useless, not in those two positions...... Something must have gone wrong. ”

Hao Zhengyi found a place to sit down, trying to figure out where the last explosive was...... Since the first three explosives can be found, it means that the other party must not be the maintenance personnel of the high-speed rail train...... With the importance that Daming attaches to the high-speed rail, it will never allow anyone to place explosives outside the high-speed rail.

Will the Infinity patch be attached to the outside of the train and the explosives will be placed inside the car?

This thought had just flashed through Hao Zhengyi's mind, and he was immediately vetoed by him...... It is impossible, with the particularity of the high-speed railway, the thickness of the outer wall will definitely isolate the signal, and it will be blown up early......

Wait, the other party wants revenge, so to speak...... Maybe the first three explosives are just a disguise, and his real purpose is in the last one!

Thinking of this, Hao Zhengyi suddenly became enlightened!

With the national strength and security that Daming has demonstrated in the international community over the years, it is impossible for the other party not to take into account...... The first three explosives can be found so easily, and they may not be within the range of the other party's expectations, this is the smoke bomb he fired, the purpose is to cover up the last explosive......

And then consider that he gave himself the question...... It shows that he is very confident in his ability, and he is taking the initiative to provoke the entire six doors! Then the topic, there is absolutely no problem!

Four explosives found three...... And it doesn't look too powerful......

Didn't the doctor of physics just say that? If the train is not running at high speed, it will not be subjected to violent shocks...... If it is simply these explosive equivalents, it will not do much damage to the train at all......
