Captain Liu suddenly became excited.
Two clicks means something is wrong, and three clicks means you need to pull it 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 didn't pull it a third time, which meant that he had discovered something!
What Captain Liu didn't tell Bai Song was that he had just talked to the director about asking divers for help, and he did get his consent.
As a result, while he was on the way, his superior called him and said that the speedboat had been found. He asked him to deploy the divers to the speedboat to explore the waters below the speedboat.
Logically speaking, even if the people on the speedboat were crazy, they would not still be in the water, they must have driven away. But the leader thought that when the speedboat exploded, some objects inside the boat must have fallen into the water. Although the value is unknown and it is difficult to salvage, it is a procedural issue.
This program is not wrong. It has exhausted the current clues and done its best, so there is nothing wrong with it.
But Captain Liu subconsciously felt that Bai Song was more reliable than their director... Thinking of this, Captain Liu himself was shocked...
There was no other way, Captain Liu could only say that the divers had already gone down and the oxygen supply was running out, and asked the leader to send new divers there.
Although saying this may offend some people, after all, asking for permission in advance is allowed, so it cannot be said to be breaking the rules.
At this moment, the problem was really discovered. Captain Liu was extremely excited and felt that he had made the right bet!
Although he thought so much, it only took a moment. Captain Liu immediately instructed the two to follow the rope to find Captain Bai.
Soon, the two of them dived near Baisong, treading water easily and maintaining the direction of their bodies in the water. Looking at Baisong again, it seemed that he had some difficulty maintaining his position in the water...
The level of this level 5 diver doesn't seem to be very high...
There was no time to complain and the two of them rushed over quickly. The policeman must have some skills to be able to find this place. After all, the visibility here is only one or two meters.
The two of them quickly saw what Bai Song was pointing at. At this time, Bai Song had already cleared away some of the mud and sand nearby.
Rivers have their advantages. If there were no ocean currents on the seabed, you wouldn't be able to see them even if you stir for a long time. But here, they can slowly carry away the turbidity.
These propellers are not powered; they are power generation devices driven by water flow and have no cutting capabilities. Three or four of them have even become entangled in something and have stopped.
This made Bai Song a little confused. The power of these power generation equipment didn't seem very high...
It seems that regular maintenance is needed? Bai Song took a closer look and found that it should be retractable.
How does this ensure oxygen supply? Why does the vibration occur?
Bai Song knew that the previous base should be where Feng Yiling lived on a daily basis. The submarine left there was a retreat, and the hydraulic door of the submarine was opened in a countercurrent manner, which would cause the door to be quickly blocked by mud and sand after it was opened, making it very difficult to explore the situation inside and find traces of the submarine.
This should be opened downstream and can be used multiple times.
In that case, the submarine was right underneath, and it had already parked.
Bai Song analyzed from this that Feng Yiling should have more than one submarine. After all, this one is only used in emergencies.
Building a base underwater is extremely difficult, especially if it is done in secret.
There is no need to build a cabin for this base that can accommodate two submarines. This will increase the difficulty of building this base exponentially. After all, submarines are not trivial things.
Bai Song just analyzed that this base should be attached under the bridge piles, and there is some equipment moving inside at this moment. The whole thing is under the mud and sand. Every time it is opened, it will quickly return to its original state as the river washes it away.
The slight vibration that can be felt on the bridge piles is not caused by the generator or the internal oxygen production equipment. Bai Song analyzed that it should be the drainage equipment.
Only high-power drainage equipment will use this kind of diesel or gasoline equipment. There is a lack of electricity underwater. After the submarine enters underwater, the water in the cabin needs to be drained, which requires the use of the engine.
However, there is a problem here. No matter what kind of internal combustion engine it is, it requires a large amount of oxygen. Compared with human consumption, a small engine can consume the oxygen needed by a person for several days in just one hour.
Using engines to generate electricity to electrolyze water to produce oxygen does not conform to the law of conservation of energy, 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 industries! This aspect is easy to conceal, and it is not difficult to get some oxygen tanks.
In other words, the oxygen below is brought from outside, not electrolyzed water, and the amount is limited.
…
In just a few dozen seconds, Bai Song thought of a lot of things and had a general analysis of this base.
It must be humid here, because the purification of the air here may rely on peroxide or external emissions, and air dehumidification is almost impossible.
emission?
If you don't see bubbles, it means there is a compressor compressing the tank?
This is really not a small thing...
If nothing unexpected happens, there must be a large amount of money stored here, or at least it used to be stored there, and this is also the source of the money getting moldy.
After thinking so much, Bai Song suddenly thought of a question. Since there may be two submarines, but only one can be placed here, where is the other one?
This thing is not small. If there are daily operations, then there are also daily patrols on the Xiangjiang River. If the submarine cannot be found, then forget it.
Unless there is a problem among the patrolmen!
Bai Song is the kind of person who can't help but analyze automatically once he comes up with a new inference, and once he has this idea, he can't stop.
The two divers discovered a steel structure several dozen centimeters below the soil and quickly asked Bai Song to come and see it. Bai Song waved his hands up and down to show that he understood and motioned for the two to float up first.
The two of them had little oxygen, so they floated up with Bai Song.
Bai Song was the first to take off his oxygen mask. Before he even got on the boat, he asked, "Captain Liu, the sonar boat you mentioned earlier, is it the water security department of our municipal bureau or branch?"
The Tianhua City Public Security Bureau has a special water security department, which is mainly responsible for some issues in Tianhe. Bai Song doesn’t know whether the water security department here is also planned in this way.
"No, the river police boats are all small speedboats. Our Xiangjiang River is not as wide as the Yangtze River. Many things are handled by the law enforcement teams of the fishery and agriculture departments. This boat is one of them." Captain Liu stretched out his hand. "What's going on down there? Come up first and we'll talk."
"Okay, let's go up and talk."
