Team Liu's mood suddenly became excited.

Two times is a situation, and three times is a need to pull up.

When the rope trembled just now, his heart trembled, and he subconsciously thought that something had happened to Bai Song, but he only pulled it twice, and did not pull it a third time, which means that there was a discovery!

What Team Liu didn't tell Bai Song was that just now he first told the director to ask the diver for help, and he did get permission.

As a result, on the way there, his superiors called him, and the speedboat found him, and asked him to transfer the divers to the speedboat to explore the waters below the speedboat.

It stands to reason that even if the person riding the speedboat is crazy, he will not still be in the water, he must have run away by car. But what the leader thought was that when the speedboat exploded, some of the objects in the boat must have fallen into the water, although the value is unknown and it is difficult to salvage, but this is a procedural problem.

This procedure is not wrong, exhausting the current clues, doing your best, naturally there is nothing wrong.

But Team Liu subconsciously felt that Bai Song was more reliable than their director... Thinking of this, Team Liu himself was taken aback...

There was no way, Team Liu could only say that the divers had gone down, and the oxygen had run out, so he asked the leader to send new divers over there.

Although it offends a little bit of people by saying this, after all, it is allowed to ask for instructions in advance, so it cannot be called unruly.

At this time, the problem was really discovered, and Team Liu was extremely excited and bet right!

Although he thought about it so much, it was just a matter of a moment, and Team Liu immediately instructed the two of them to follow the rope to find Captain Bai.

Soon, the two of them dived near the white pine, stepping on the water very easily, maintaining the direction of their bodies in the current. Looking at the white pine again, it seems that it is a little difficult to maintain its position in the water...

The level of these Level 5 divers doesn't seem to be very high...

There was no time to complain, the two of them rushed over quickly, and the police could find out here, they did have their own skills, after all, the visibility here would be one or two meters.

The two of them also quickly saw what Bai Song was referring to, and at this time, Bai Song had already stirred up a little bit of the mud and sand in the vicinity.

Rivers have the benefits of rivers, if there is no current at the bottom of the sea, you can't see it for a long time, but here you can slowly take away the turbidity.

The propellers weren't powered, they were powered by the current, they didn't have much cutting power, and three or four of them had been caught in something and stopped.

This made Bai Song a little puzzled, the power of these power generation equipment does not seem to be high...

It seems that regular maintenance is still needed? Bai Song took a closer look and found that this should be able to be scalable.

How does this ensure the supply of oxygen, and why does it cause the vibrations?

Bai Song knew that the previous base should be the place where Feng Yiling lived every day, and the submarine left there was a way out, and the hydraulic door of the submarine was opened against the current, which would make it clear that the door would be silted up soon after opening, and it would be difficult to explore the situation inside and find the traces of the submarine.

And here it should be opened downstream, which can be used multiple times.

In this case, the submarine just now is under this, and it has been parked.

Bai Song analyzed one thing from this, that is, Feng Yiling should have more than one submarine, after all, this one is only used in emergencies.

Building a base underwater is extremely difficult in itself, especially if it is built on the sly.

There is no need to build a compartment that can put two submarines in this base, which will make the construction of this base more difficult, after all, submarines are not gadgets.

Bai Song has just analyzed, this base should be attached to the bridge pile, and there is something moving in it at this time, the whole is under the sediment, each time it is opened, with the river washing, it can quickly be restored to its original state.

The slight vibration that can be felt on the bridge pile is not a generator or an internal oxygen generator, but a drainage device.

Only high-power drainage equipment will use this diesel or gasoline equipment, there is a lack of electricity underwater, and after the submarine enters the water, the water in the compartment needs to be discharged, which has to use the engine.

However, the problem here is that no matter what kind of internal combustion engine it is, it needs a lot of oxygen, and a small engine can consume a person's oxygen for several days in an hour compared to human consumption.

It is not in accordance with the law of conservation of energy to use the engine to generate electricity and electrolyze water to produce oxygen, so only compressed oxygen can be used, and most of the space in the submarine must be used to transport oxygen tanks...

Feng Yiling itself has some medical-related black products! In this regard, it is easy to hide people's eyes, and there is no difficulty in getting some oxygen tanks.

In other words, the oxygen below is taken out and not electrolyzed water, and the quantity is limited.

...

In just a few tens of seconds, Bai Song thought of a lot of things and had a general analysis of this base.

Here, it must be humid, because the purification of the air below may depend on peroxide or external emissions, and air dehumidification is almost impossible.

Emission?

If you don't see air bubbles, is there a compressor compressed into the tank?

It's not a small deal...

Below, if nothing else, there must be a large amount of money deposited, at least once saved, which is also the source of money mold.

After thinking about it so much, Bai Song suddenly thought of a question, since there may be two submarines, only one can be placed here, then, where is the other one?

This thing is not small, if there is also daily action, then there is also a daily river patrol here in Xiangjiang, if you can't find a submarine, then don't mix it up.

Unless, among the patrol people, there is a problem!

Bai Song is the kind of person who involuntarily analyzes a new inference once he has it, and once he has this idea, he will be out of control.

The two divers found a steel structure dozens of centimeters under the soil, and hurriedly asked Bai Song to look, Bai Song waved his hand up and down, indicating that he knew, and motioned for the two to float up first.

The two of them didn't have much oxygen, so they floated up with the white pine.

Bai Song was the first to take off his oxygen mask, and before he got on the boat, he hurriedly asked: "Team Liu, is the sonar boat you mentioned earlier the water security section of our city bureau or sub-bureau?"

The Tianhua City Public Security Bureau has a special water security section directly under it, which is mainly responsible for some problems in Tianhe, and Bai Song doesn't know if the water security department here is also planning like this.

"No, the Jiang police boats are all small runabouts, our Xiangjiang River is not as wide as the Yangtze River, and many things are the law enforcement teams of the fishery and agriculture departments, and this boat is. Team Liu stretched out his hand, "What's the situation below, you guys come up first." ”

"Okay, let's go up and talk about it. ”
