The most beautiful world to the truth.

Whether it was the sudden message from his father or the dog's crazy wagging tail, Bai Song felt the incomparable Shutai.

What is more important than this?

At this time, Bai Song does not need to work hard, and all kinds of knowledge in his head can be at his fingertips, and he is in a very good state.

Driving into the car, Bai Song quickly found the river about 15 kilometers away from the basement according to the map, parked the car aside, and then waited for other local support.

The distance between the two sides adds up to 20,000 meters, and it takes a lot of manpower and material resources to do a check and control.

After all, soon, the downstream sonar ship arrived, and the detection range of the sonar ship, stopping at the position of Baisong, can basically cover the entire 10-kilometer-long groundwater area!

The rest is to find a professional underwater detection robot and find it slowly.

"She won't have other underground passages, right?" Wang Liang seemed to understand what Bai Song meant. Wang Liang felt that Bai Song should have gotten specific clues and learned that Feng Yiling's real hiding place was in this river, and it was also a real underwater base, which was larger than the cabin of the second gate there just now.

"If there were, it wouldn't mold like that. Bai Song is quite confident: "This should be a pure underwater base, and this kind of base is actually not difficult to build, especially if there are other piles..."

Speaking of this, Bai Song hurriedly said, "Bring the map!"

Bridge!

Bai Song took the map on Wang Liang's mobile phone and zoomed in to look at it.

More than a kilometer ahead, there is a bridge across the Xiangjiang River!

The river is much wider and the depth is estimated to be shallower than just now, and there is a bridge across the river that has been built for a while.

"You mean, the base is under the bridge?" Wang Liang understood what Bai Song meant.

"yes, go over and have a look. ”

After Bai Song finished speaking, he didn't talk nonsense, started the car directly, and went straight to the bridge.

At the moment he was a little nervous, very nervous, the steering wheel of the car was about to lose his grip, and he had to reduce his speed.

Just over a kilometer away, the car quickly stopped next to the bridge.

"It's here, it must be here, that's right!" Bai Song almost shouted.

Looking at the structure of this bridge, Bai Song slapped his thigh, "Perfect!

"Are you okay?" Wang Liang touched Bai Song's head, found that he didn't have a fever, and was just about to breathe a sigh of relief, when he suddenly thought: Neuropathy has nothing to do with fever or not...

"You don't know!" Bai Song said: "I have also read books on architecture, including bridge construction!"

Compared with the Yangtze River, the Xiangjiang River is not half a star, so although this bridge is not small, it is only an ordinary 'bridge', not up to the level of a 'special bridge'. In China's bridge classification, extra-large bridges refer to highway bridges with a total length of more than 1,000 meters or a single hole span greater than 150 meters, as well as railway bridges with a bridge deck length greater than 500 meters.

Highway bridges are generally between 100 and 1,000 meters.

The bridge is about 300 meters long, which belongs to the small existence of the bridge, and the bridge pile uses the most advanced immersed pipe construction method ten years ago, that is, the pipe is sunk into the water, driven into a sufficient depth, and then filled with concrete, the bridge pile in this case is very solid, and it will not be broken in another forty or fifty years.

According to China's "Highway Bridge and Culvert Maintenance Specification", the main inspection content of piers and foundations is mainly whether the piers and foundation piles are sliding, tilting, sinking or frozen pulling, whether there is a problem with the filling of the back of the platform, and whether there is frost heave, weathering, cracking, spalling, exposed ribs, block fracture, through joint disconnection, deformation, whether the masonry drain hole is blocked, leaking, erosion...

If necessary, divers should be sent to the deep-water foundation of the bridge and extra-large bridge for diving inspection.

In fact, many extra-large bridges will be regularly dived and inspected, but the above phenomena do not exist on the bridge, so there will be no diving inspection!

The most important thing is that in this place, the water flow of the Xiangjiang River continues gently, and the bridge piles are sharp corners, even if there are people who jump into the river, they will not stay in this place, so the bridge piers here, the position below 20 meters, almost no one will ever check!

It's much easier to build a base there than to fix it directly to the riverbed!"

...

After Bai Song finished speaking, his face was confused.

Flowey and Flowey also looked at White Pine with innocent faces.

"You know so much, do your parents know?" Wang Liang said that he understood, but he didn't understand why Bai Song was talking about something.

Bai Song didn't bother to pay attention to Wang Liang, then drove and parked the car on the bridge.

This bridge is not a trunk bridge nearby, and the traffic flow is not very large, so Bai Song parked the car tightly on the side of the road, and everyone got out of the car.

Flowey and Blossom sniffed everywhere and still found nothing.

Bai Song is not discouraged, this is also normal, after all, if you can smell it through such a deep river, then this is not a dog nose, but clairvoyance, no, it is a perspective nose.

At this moment, Team Liu's phone called.

"Team Bai, is it convenient for you to contact the Qin detachment?" asked Team Liu with some twist.

"What's wrong?" Bai Song sensed a bad premonition.

"Hmm... The new leader... Or are you ready to carry out the original plan. Team Liu hesitated, but still said it.

"Understood. Bai Song also understood that he didn't give any evidence, and the leaders here would definitely not easily believe that he was a little hairy child.

But if you want no fault, you don't want merit, and it can't be called a wrong thing, after all, the leader thinks about big things, and the speedboat must be grasped, if you can't catch it, whoever is the leader is responsible!

Team Liu is 40 years old this year, the deputy captain of the criminal police of the county bureau, it is when he is in the prime of life, he is not afraid of taking this responsibility, and he trusts Bai Song very much, but he is far from the level.

This made him very envious of Bai Song, who was so young and was in charge of this matter!

Where can this white pine leader be regarded as delegating power, it is simply conniving... But then again, people do have the capital to connive...

"You don't need to contact the Qin detachment, Team Liu, I don't need so many police forces, your side, the previous two divers, can you lend me another one? Bai Song asked.

"This should be no problem, I'll talk to the leader, I guess I will be able to transfer you over soon, where is your position?" Team Liu felt that this matter was still fine. However, he still has to report to the leader.

Even if it is very likely that there will be a major discovery and meritorious service, you can't offend the leader and secretly send someone to it... To be precise, the more likely it is that there will be a big discovery, the more important it is to report it, otherwise in the future...

Bai Song didn't think about it so much, sent the location over, and waited quietly.

The water of the Xiangjiang River, the back waves lap the front waves, and it does not stop for a moment.
