Police Detective

As the ship approached from far away, Bai Song and others also ran under the bridge to greet it.

"Captain Bai, the speedboat has been found." Captain Liu saw Bai Song and said it first, which was basically what Bai Song imagined.

An unknown number of barrels of gasoline were sprinkled on the speedboat. The escapees lit the gasoline, causing the speedboat to explode. When it was discovered, the boat had burned to nothing. The boat that had just arrived tried to get water to extinguish the fire, but was unable to use the gasoline. It was of no use, I could only watch the speedboat burn.

This made Bai Song breathe a sigh of relief. In his opinion, his father must have found the speedboat in advance to discover this clue. He was also worried that his father's methods would be discovered, but this situation would definitely not happen.

It seems that Bai Yulong has already thought about this situation, that is, the speedboat will try to destroy it before it is found.

Older gingers are more spicy.

But Bai Song still doesn't understand, so what if he is discovered? Isn't this a matter of great merit?

We are all colleagues, is there any need to be so sneaky?

"Team White, the sonar ship just passed by and no submersible was found," Team Liu said.

"Yes, I know." Bai Song nodded: "Let's check this underwater. Is there any spare diving equipment here?"

"Yes." Captain Liu looked surprised: "Are you going to go down? No, no, this water is too turbid. Our divers here are all professionals, so you can't go down."

"I am also a professional, SPECIAL COURSES, level 5 diver." Bai Song was talking nonsense, which made Wang Liang curl his lips. Over the years, he had personally watched Bai Song's ability to talk nonsense gradually improve. In the past, I couldn't even deceive a little girl, but now I can even deceive the captain of the criminal police brigade.

There are basically 12 levels of divers at present. Generally, level 2 can be used to do some night diving and deep diving. Level 4 can be used as a rescuer. Level 6 is the highest level for amateurs. Above that, there are instructors, etc. .

Both divers have Level 4 certificates. When Bai Song said this, he was stunned for a moment. Is this policeman still an all-rounder?

Team Liu asked two divers before he found out that Bai Song's level was actually higher, but he still said: "You are not familiar with this water area, so don't show off."

"It's okay. There is a rope. If I have a problem, just pull the rope three times and you will pull me up." Bai Songyun said calmly.

"Okay, it's not a big problem if you have an oxygen tank." Team Liu agreed.

A group of six people boarded the boat together, and Wang Liang was left on the shore to accompany the dog. There was no way, Li Dongfang was much stronger than him, and he could still help at a critical moment.

Bai Song was a little slow when putting on the equipment. Although he had used scuba, he had only used it twice. He was far from being proficient. It can only be said that his swimming and diving skills were not bad, but they were smooth. He put on the equipment and went into the water with the two divers.

Scuba officially appeared less than a hundred years ago. It allows divers to breathe oxygen at a pressure of one atmosphere from an oxygen tank at a depth of 50 meters. Bai Song remained calm and followed the two divers to inspect the bridge. pile.

The visibility under water is slightly better than on the surface. Looking down from the water surface, you can't see clearly even half a meter away. There is no light refraction underwater, but you can have a visibility of one or two meters.

Bai Song has just considered the problem here. The base cannot be dug into the bridge piles. This will easily cause quality problems of the bridge piles. Moreover, the bridge piles are solid after pouring. It is too difficult to dig out the holes. It should be an attached type. of.

The dive was relatively slow, and the three of them had to fight against the flow of some rivers. Fortunately, the bridge piles below were somewhat corroded and felt like pits. They could dive slowly by holding on to the bridge piles.

Slowly, the three of them reached the bottom.

Before coming down, two divers who had just gone into the water once told Bai Song that the bottom here is some sand with mud, and you must be careful when moving around here. It's not that I'm worried about sinking in. After all, I'm a diver. The main thing is that if I flutter a little, I won't be able to see anything.

Under the illumination of a strong flashlight, the three of them conducted a detailed investigation around the bridge pile, but found nothing.

You need to pay more attention when going up than when going down. Water at a depth of 20 meters already has two atmospheres of pressure. After reaching the surface, the two divers suddenly discovered a problem: there was not much oxygen.

They have already dived once and conducted a more detailed exploration there. Now each person's oxygen should only be enough for about 15 minutes.

One more dive is not enough, but it will be more difficult to deal with other situations.

Bai Song discussed it and asked him to explore the other bridge piles. If any problems were found, he would call them.

Maybe Bai Song had been holding on to the bridge pile just now and didn't show any level of diving, so the two divers relatively recognized him. After the boat reached the next bridge pile, Bai Song dived directly.

To be honest, I was still a little nervous, but the environment here was not too complicated, and Bai Song was quite capable.

After reaching the water, Bai Song carefully sank to the bottom, but still started to circle around the bridge piles.

The sound of running water was relatively noisy, and Bai Song couldn't hear other sounds, so he didn't feel anything special. Because he wasn't very skilled, he kept holding on to the bridge piles and never let go.

After walking to the back of the bridge pile, Bai Song suddenly felt a different tremor on the bridge pile.

The tremor was so small that if Bai Song hadn't been supporting him, he wouldn't have been able to feel it.

Bai Song suddenly became nervous and descended to the bottom.

There was nothing below, which made Bai Song a little confused. He used a flashlight to illuminate it everywhere, but he didn't find any problems.

He was a very sensitive person and could not easily give up on this discovery, so Bai Song broke away from the bridge pile and swam out nearby.

At this current speed, it was still difficult for Bai Song to control the direction, so he could only try to change direction while swimming against the current.

After a lot of effort, Bai Song swam an effective distance of seven or eight meters.

Then he walked around the area, and Bai Song suddenly saw something unusual.

There was an abnormal flow of water in one place. As Bai Song swam closer, he discovered that there was a set of propellers with plastic blades, just sitting on the bottom of the river. There were as many as a dozen in number, and there should be transmission equipment connected to them below.

Are these the blades of an underwater generator? Bai Song saw the problem at a glance, and pulled the rope twice to indicate to the other two that they could come down through the secret signal he had just said.

The existence of this set of blades can continuously provide sufficient electrical energy to the underwater base.

Bai Song's heartbeat was a little fast. He understood that the real base had been found. All that was left was to open the urn. It was time to find out what was inside.

Halfway through the business trip, the people in the city where I was located had finished arresting them.

If I go to the next city tomorrow, there is no guarantee that I can update it the day after tomorrow.
