Of course, Duolun would not worry about the statement of the man in front of him, since he had already taken the gift from others, he would not throw it out easily.

"Don't worry, we've learned a little bit before that"

With that, Duolun swiped the tablet between his fingertips a few times, and the island mentioned earlier appeared in the frame.

As I said before, this island is not big, but it is impossible to see the whole picture of this island on the map, because there are three iron curtain devices on this small island, which form a "zigzag" magnetic field at a distance of 50 meters above the island, which cannot be penetrated by satellites, and various electronic devices, including mobile phones, cannot be used.

"Is there a way to fix his power system so that the Iron Curtain can be lifted"

"We have thought about it for a long time, but it will not work at all, and we have found through analysis that this electricity is generated by itself from the underground water power on the island, and it is in a very hidden location in the depths, so it is impossible to take a direct attack."

"Then what do you mean by not being able to use electronic devices," Long Jianfei continued to ask.

"Speaking of which, we were a little strange before, but we made a subtle discovery that only one of the rooms was not disturbed by the magnetic field outside."

Duolun scratched the tablet again for a few years and found a video.

I saw that the video was a picture of Karina and her boyfriend, but there was no problem with these.

"Note the 12th second," Doron added.

Long Jianfei's eyes were glued to the screen, for fear of missing every one.

At the 12-second position, a person on the left side of the screen walks to the right, and it takes less than a second.

"See", Doren will press the pause button.

"He's using his phone",

"That's right," Duolun took out a piece of printed colored paper from his office bag and handed it to Long Jianfei.

"It's been post-processed, and you can see Apple's logo,"

After watching it for a while, Long Jianfei picked up the tablet and looked at the previous video screen, and suddenly his eyes lit up.

"Have you ever analyzed the drainage facilities of the power system?"

"What do you mean?"

Long Jianfei took out the pen and paper on the table and drew a few strokes, this is a diagram of the electric power system.

"Under normal circumstances, the first condition for the establishment of hydraulic power is to have a huge gap. In the specific drop ratio is relatively large, the river channel has a narrow valley or the artificial construction of a high dam can produce a large drop, in order to produce a strong downward impulse and horizontal flow velocity; second, there must be a huge flow. There is a drop alone, and without a large flow rate, it is impossible to form a strong hydraulic force. Therefore, the flow rate plus the drop difference is the main basis for whether the hydraulic power is abundant or not. The drop in water that we're using here is actually using the gravitational energy of the water,"

Duolun understood what Long Jianfei said,

"But the height of this island is almost on the same line as the sea level, or even lower than the sea level, so how did this drop come about...... But that shouldn't be the direction of this mission." Halfway through speaking, Duolun seemed to think of something again.

Long Jianfei smiled,

"It's true that this is not our direction, but you know, hydropower generation is not only about the flow rate, but also about the drain, so where is the drain?"

Duolun stood up and patted him lightly, as if encouraging.

"We've thought of this too, look here"

The tablet shows a satellite map, which is a photograph taken by a terrestrial thermal phasing analyzer.

"After analysis, the heat here is not significantly higher than that of other environments, indicating that this is the drain for power generation, but it does not indicate that it can enter from here, the heat here has exceeded the range that the human body can bear, once people go in, it is equivalent to entering the steamer, no one will do this,"

"Well, just make sure this is a drain,"

"Dragon, do you really want to enter from here, no, I firmly disagree, this operation is not for you to die, if so, I will refuse Carter's request",

Long Jianfei waved his hand again and again, motioning for him to sit down.

"Look here," Long Jianfei enlarged an icon.

This shows yes, in a small place outside the edge of the Iron Curtain, not very noticeable.

"The rest of the position is almost covered by the Iron Curtain, and Wei Du is here, which means that this was formed after the Iron Curtain installation, and from the picture, it was formed by blowing and filling"

After Duolun confirmed again, he picked up his phone and pulled out the number.

"Kelly, zoom in on the H5 position of satellite photo 3 and see how it was formed."

Soon the other end of the phone gave feedback.

Duolun put down his phone and looked at Long Jianfei with some excitement,

"It's formed by blowing, what are your plans?"

"Now it's certain that there's an artificial passage down there, and the dirt coming out of this can be concluded to be quite small," Long Jianfei analyzed.

Duoren nodded, motioning for him to continue.

"Have you checked the speed of the water here", Long Jianfei raised his head and looked at Duolun, he knew that the other party would not even do nothing.

Seeing that the other person nodded, he pointed to the map again.

"As I said earlier, there are a lot of spherical things in the water, so if there is a flow of water passing through, will these devices still be arranged, and if there are any, it will definitely be sucked in by the current and the gains outweigh the losses."

Seeing Long Jianfei's analysis, Duolun's eyes lit up,

"Well, your analysis makes sense, if that's the case, then here's their loophole,"

"That's just one of them, I have another question, which is that there is such a large flow of water here, so there must be a grid device to prevent debris from being sucked in and destroying the equipment inside. ”

Duolun smiled at this time, and took out a piece of paper from his bag,

"You're right, look at this, this was filmed by an underwater robot,"

Although the image is not too clear, it can also be seen that this is the inlet taken by the inlet, there is a flow line, the flow rate, and it is a five-meter square passage, and there is a debris fence at the entrance.

"Damn, you haven't taken this thing out soon," Long Jianfei said.

"Hahaha, don't you want to see what your brother thinks"

"I Rely on You"

"Hey, you can't scold, I understand what this word means,"

Long Jianfei pretended to punch Duolun a few times, and only stopped after Duolun begged for mercy.

"You know, we won't fight unprepared, but this time, given the secrecy of the operation, only a few people know about it."

Long Jianfei just smiled, what he had to think about now was how to do it better. He pointed to the map.

"The Iron Curtain device needs a lot of power to keep it running, and this kind of device works 24 hours a day, and the equipment will be repaired, so they must have a top-down notification connection here. ”

"If, as you say, there's a turbine-like blade waiting for you inside and tearing you to shreds,"

Long Jianfei didn't answer, he thought for a while and then took out a pen and paper again to draw an object.

"I think you'll get it."

Duolun looked closely, a smile gradually appeared on his face, and he patted Long Jianfei's shoulder vigorously.

He drew something in the shape of a balloon, two in front and two, with a person in the middle, the balloon in front of it entered to reduce the speed of the water flow and ensure the safety of personnel, and then inflated the balloon in the back to block the entry of the water flow.

"I didn't expect that", Duolun's mouth opened wide, a look of incredulity.

"Yes, there is only this method at present, but this kind of balloon needs to be dissolved in water, otherwise the balloon will be involved in the turbine and cause shutdown after it is broken, which will be discovered by the other party", Long Jianfei further explained.

"Don't worry, I'll contact Kelly right now."

Now Long Jianfei once again set his eyes on Duolun, who was looked straight at him.

"You can tell me what Hannah is responsible for now,"

"Of course, before we talk to you, we think it's better to go by water, and Hannah is trying to destroy that little water ball in the sea,"

"I need it now, otherwise I can't get into the water,"

"Of course, I also thought about it just now, she lives next door to you, if you can, you can listen to her advice, and of course you can also take this opportunity to have a good talk", Doron blinked vigorously at the other as he spoke. Turned around and walked out of the suite.

The so-called etiquette of Americans is nothing more than a story of ups and downs, although Long Jianfei is not completely clean, but he also knows what proportionality is, and proportionality is that he has a girlfriend, and there seems to be more than one.

Hannah's arrival didn't happen anything big, which made Duolun underestimate Long Jianfei. The three of them revisited the room to discuss the details of the operation.
