Yu Fei has always been sneaking underwater because his face is too easily exposed. If someone accidentally discovers him, all his previous efforts may be wasted, and he may even be strangled by all the masters in the tunnel.

So for the sake of safety, it doesn't matter even if it means wasting a little more effort.

It was Yu Fei who discovered that the speed of water entering the tunnel exceeded his expectation. He originally thought that it would take at least five or six hours for the tunnel to be almost full, but now it seems that it will not take that much time at all.

If the water in the tunnel is filled, everyone here may drown, and by then I won't be able to know anything important.

Yu Fei was worried that the important things would be destroyed by someone, and even more worried that the people who knew these things would be drowned.

So Yu Fei had to speed up and complete the task before people were drowned and things were damaged, and then he started thinking about how to leave.

Now Yu Fei cannot control the speed of water entering the tunnel, so he can only control his own speed.

The second-level researcher's computer had already been taken away by Yu Fei, but in order to prevent his sudden change in habits from being suspected, Yu Fei asked him to get another person's computer. Anyway, everyone's standard computers here are similar.

, so others can’t see it.

In this way, more than a dozen vehicles moved forward, and they stopped because they encountered the bus again. If they guessed correctly, this was another vehicle transporting researchers.

It's just that this car has not been modified, and without the immoral bathroom settings, Yu Fei would not be able to enter the car quietly.

So it was up to the abilities of these three people. The three of them knocked on the car door and exchanged a few words with the people in the car through the window. The car door was forced open manually. Just to make it easier to get in and out, they simply didn't close it.

Otherwise, as the water level rises and the water pressure changes, it will become more and more difficult for them to open the door.

After Yu Fei made a thorough observation, he found that in addition to the three people he brought, there were actually seventeen people in the car, and the seats were almost full.

Yu Fei made an agreement with the second-level researcher in the optical department. If the person he was looking for was in the car, he would be asked to stay in the car. If the person was not there, he would be asked to leave the car and search.

The other person had been staying in the car for several minutes, so Yu Fei was sure that the person he was looking for was in the car.

There were just too many people in the car, and it was really hard for Yu Fei to take action. With so many people inside, if one of them made too much noise, he would be exposed.

The number of people in this tunnel exceeded Yu Fei's expectation. Almost every vehicle was guarded by people. The more important vehicles were all equipped with experts, and the ordinary vehicles were guarded by guns.

Only then did Yu Fei think that he hadn't thought it through carefully. If he had made an agreement in advance, he could tell the second-level researcher that when he couldn't find a chance to go in, he could just trick the people inside out alone, saying he wanted to talk.

Confidential content is also good.

But because I hadn’t thought about it in such detail before, I didn’t agree on this.

But at this time, the advantage of having more skills and not being overwhelmed comes to light. Yu Fei can't run out to communicate with this person, but he can transmit sounds for a year!

I have added passwords to my hypnosis skills, so even though I am not giving orders directly, when I use my mind to transmit my voice, if I add passwords to ask the other party to do something, the other party will also comply.

Yu Fei used his mind to communicate his new orders.

After receiving the order, the second-level researcher immediately asked to talk alone so as not to be inconvenient for others to hear, and then deceived the person in charge of the new department in the car and walked out of the car.

After the two got off the car, they supported each other and walked towards the back of the car, because there was said to be a dining car behind the car and it was not a place for meals now.

With no one.

The dining car is also a bus, but the advantage is that there is no one inside at this time, so there are no experts guarding it.

Like an underwater monster, Yu Fei followed the two people silently to the dining car. There was a driver in the car. The driver opened the door and the two entered the dining area at the back.

Before entering the car, the second-level researcher looked around to make sure no one was paying attention, and quickly kicked Yu Fei who was lurking under his feet.

The moment the two of them got into the dining car, Yu Fei suddenly appeared from the bottom of the water, like a slippery loach, and quickly entered the car.

The supervisor who had been fooled heard the sound of water droplets falling behind him. As soon as he turned his head, he happened to meet Yu Fei's raised hand.

Now Yu Fei is becoming more and more proficient in hypnosis. Although there is still water on his fingers, it does not affect his performance.

It was obvious that the water droplets had an effect on the other party, so the hypnosis could be completed in a few seconds. It took Yu Fei more than twenty seconds to confirm that the other party was completely controlled by his hypnosis.

Next came a very skilled inquiry. It turned out that this person was in charge of a special department called the selection and production of thermal insulation materials, as well as the research on the heating effect of light on substances.

Yu Fei is almost certain that what the Mao Xiong Country is researching is a kind of laser weapon. Although the whole world is researching it now, it seems that theirs is more advanced. It seems that they are holding back their ultimate move and intend to develop it.

Then it became a blockbuster.

Then this department seems to have made great progress. They have synthesized a special material. Not only its high temperature resistance is the best in the world, it is also focused on light boar research, especially the reflection of light and the control of temperature.

, in the other party’s view, it would be difficult for other countries to catch up with research in this area in thirty years.

Of course you're welcome to this good thing, Yu Fei, and this is mainly about technology, it doesn't matter whether you want the actual thing or not.

However, this person does not have the habit of carrying all the information with him, and all of it is stored in the device.

Yu Fei asked him to get it, and the hypnotized person naturally obeyed Yu Fei's words.

Yu Fei waited in the dining car for half an hour before the other party came back with difficulty, holding several hard drives in his hands, because they had so much research information that even one hard drive could not fit in it.

To truly develop a cutting-edge technology, the research required is too complicated. Sometimes it takes several years to try out a single data. Small changes in various data will result in completely different results.

Although Yu Fei only wanted the final research results, the other party told Yu Fei that in fact, their research had not yet obtained the final results. There were still some difficulties that had not been overcome, and there was still room for improvement in certain data, so all of their

Research data is extremely valuable.

After getting all this data back, scientists in their own country can save a lot of effort, avoid the wrong options they have eliminated, and directly study the remaining data and possibilities, saving a lot of time and money.

This person even brought back to Yu Fei some related materials they had made. They were all metal sheets. Some looked like mirrors, and some looked like iron sheets, but they were all of great value, because the other party said that this was

They have studied the results for decades.

Yu Fei once again obtained a piece of research information. He felt very satisfied. This progress was actually not bad. He obtained a technology in half an hour. Before the flood completely flooded the tunnel, he might be able to collect all the Dragon Balls.

All relevant technologies are included.

After getting the second research information, Yu Fei began to consider the third one.

At this time, the tunnel outside suddenly became noisy. Yu Fei heard someone shouting to let everyone

People should not touch water casually, and avoid contact with surrounding conductive objects as much as possible to prevent electric shock.

Yu Fei was stunned for a moment and understood the reason. Maybe there was a leak somewhere, and he was afraid of electrocuting one of his own.

Yu Fei quietly approached the door and touched the water below with his fingers. There was a faint numbing feeling in his fingers.

This shows that there is indeed electricity in the water. The conduction of mental signals by human nerves and the transmission of instructions from the brain to the whole body are essentially electrons propagating.

Therefore, when a person is electrocuted, the person's body will be out of control, and even the current may cause wrong signals, causing all the person's muscles to tighten.

However, Yu Fei felt fine about such an electric current. He could still bear it. Ordinary people could bear it for the time being. If it increased further, it might cause the person's body to lose control.

This is equivalent to creating a problem for Yu Fei. The two researchers controlled by him can no longer go out to help Yu Fei. Even if they can't be killed temporarily, it would be too abnormal for the two of them to go out.

So it seems that the use value of these two people is not very great, but there are no useless people in the world. It depends on how you use each other's value.

Yu Fei inquired, and the two roughly told Yu Fei the location of the next research department, and chatted on the phone for a few words as if they were chatting, and found out each other's location.

Then Yu Fei gave an order to the two men and quietly rowed into the water and left.

Although Yu Fei felt a slight numbness due to the electric current in the water, it was still completely bearable for the time being.

Not long after Yu Fei left, the drama between the two people began. One person jumped into the water, and the other person followed suit, holding a table knife in his hand.

"Help! He's killing someone!"

A man ran away shouting.

"I'll kill you! My point of view is right, your research is worthless! You are wasting money, kill the money you save and let me do research!"

The other one raised a knife and chased while shouting.

"My research is right! You trash, you liar, you are just cheating on research funds!"

The escapees cursed as they ran.

"If you dare to call me a liar, I will kill you!"

…

The two of them were running and shouting to chase each other. Although there were sounds inside, everyone communicated in whispers, so the two people's shouts of killing were very obvious and spread far away.

Suddenly, the attention of everyone within a few hundred meters of the two people was drawn, and they all looked towards these two distinguished researchers.

A master was ready to come to rescue the people, but when the master just arrived, the man who escaped seemed to have gone crazy and turned back violently. The two of them fought together, and the knife penetrated them during the fight.

He hit a person's body, and the blood immediately dyed the water red.

Sure enough, it is human nature to watch the excitement no matter where we go. Many people are in the car or on the roof of the car, stretching their heads to look at these two people. People's attention is attracted by these two people.

Although the tunnel does not have a straight line, the arc is not very large, so what happens here can be roughly seen by people hundreds of meters away. Many people in the car crowded to one side, and everyone was vying to see it.

What the hell is going on here.

At this time, Yu Fei, who had left long ago, had arrived at the next department.
Chapter completed!
