Police Detective

Bai Song stared at this text message for several seconds before confirming that the sender was indeed:

Dad!

Bai Song never expected that he would receive a text message from Bai Yulong! ! !

Dad is actually here! ! !

Bai Song looked at the text message and was speechless.

"Feng, I have entered his home without taking the speedboat. It will be deleted after reading."

There were only thirteen words. Bai Song read it once, deleted it subconsciously, and then slowly thought about the meaning of these words.

"Captain Bai? Captain Bai?" Team Liu asked anxiously several times before Bai Song came back to his senses.

"Oh oh oh, I'm distracted." In just a few dozen seconds, Bai Song had dozens of thoughts flashing through his mind, but he still didn't recover from the shock. These thirteen words contained so much information that it made his head feel buzzing.

"The clue you just mentioned?" Captain Liu was a little anxious, but still lowered his voice, for fear of disturbing Bai Song's speculation. If Bai Song was not indeed ten years older than his son, he almost blurted out "you" .

"Team Liu, what is the current flow rate of the Xiangjiang River this season?" Bai Song asked.

"I just measured it when the divers went into the water. Now it's about 1.5 meters per second." Captain Liu said directly, without asking Bai Song why.

"The speed is 1.5 meters per second, which is equivalent to 5.4 kilometers per hour. The flow speed is almost equal to 3 knots. Calculated based on the maximum speed of a small civilian submarine of 10 knots, the actual speed of the countercurrent is almost 7 knots, which is about 13 kilometers per hour. From just now By now, 35 minutes should have passed since the helicopter discovered the problem. In other words, the distance of the countercurrent is about seven or eight kilometers." Bai Song reasoned on his own: "If we estimate the maximum speed of a small civilian submarine, it does not exceed 15 knots, no less than 8 knots, then the range should be about four kilometers to twelve kilometers upstream."

Before Captain Liu could speak, Bai Song continued: "If it is going downstream, the range should be between eleven and eighteen kilometers downstream.

The upstream is closer to Hetan City, and the downstream is closer to Changhe City. Judging from the clue that Zheng Can's starting point for transporting money was in Changhe City, the highest probability is that the submarine went downstream, and the speedboat should be a cover. Used for pathfinding and attraction. Once a water patrol vessel is discovered, the speedboat has enough maneuverability to lead away the vessel that may have sonar.

Therefore, Team Liu reduced his strength and used more than half of his strength to focus on searching the river section 10 kilometers to 20 kilometers downstream from where the divers dived, searching for buildings in Hanoi, and intensifying investigations on both sides of the river. "

"What?" Captain Liu listened to Bai Song talking to himself for a long time. He was at a loss and kept talking. Why did he start to count the fifth grade application questions? His son had just used these questions to test him a few days ago.

After calming down for a few seconds, Captain Liu said: "You mean, are you sure there is a submarine, and it is stopping at the distance you mentioned downstream, right?"

"That's right," Bai Song said, "We have already entered the base. There should be some special anti-sonar means and other instruments are needed."

"White Team", Team Liu called his duties, "The on-site command will soon be handed over to the leaders of the Changhe City Bureau. I will report your plan now. Can you tell me where you got the intelligence clues from?" ?"

"You can trust me." Bai Song turned to look at Huahua and Huahua, "If you have any problems, I will be responsible for them."

"Then I understand." Team Liu hung up the phone.

After hanging up the phone, Wang Liang and others were very excited and quickly asked Bai Song, what was the specific situation?

Bai Song thought about his father's words, but still didn't say anything. He just shook his head, picked up his cell phone, and dialed Wang Huadong's number.

It was easy to talk about everything else, but what Bai Song was most concerned about was Ji Yue's situation.

"How's it going?" Bai Song dialed the phone and asked immediately.

"We entered the emergency room. One of the nails was inserted into the intestines from the back. The other two nails were fine, but one of them almost entered the ventricle." Wang Huadong said: "However, the doctor said that Ji Yue's life was really serious. , and, thank you for sending it here early.”

Bai Song breathed a sigh of relief and relaxed a little. Although Ji Yue was not out of danger yet, the situation was basically not serious, as long as the doctor said so.

Even if the bullet penetrates the intestines, and at worst a piece of it is amputated, as long as it does not affect the main organs or cause large-scale infection, everything will be fine.

When listening to others talk about their illness, the words after "but" and "however" are useful. The first words are better, but the words after "but" are useless.

The three problems that Bai Song was most worried about, including damage to important organs, poisonous nails, and disorders caused by foreign bodies, did not occur. It was really a blessing among misfortunes.

How important is Ji Yue's move?

If there is no obstruction from Ji Yue, a nail of a few centimeters would be fatal to a dog if it hits the head. Once the dog dies, if you want to find this underground building, you have to rely on other dogs or related metal detectors, or you may need to trial.

This all takes at least half an hour.

Moreover, if Ji Yue had not been injured, there would not have been the helicopter incident, let alone the discovery of the speedboat. This case could not be delayed.

After all the efforts, the timeline was finally caught up, and Bai Yulong's text message made it possible to catch up on the clues that had been left behind for half an hour.

The most important things about intelligence are timeliness, authenticity and effectiveness. The latter two can often be obtained through hard work, but obtaining timely information often requires luck.

What is father doing?

Bai Song didn't know, but Bai Song felt that he had figured out many problems at once.

"We are very close to the 10-20 kilometers downstream I mentioned. Let's go to the side here and wait 15 kilometers away." Bai Song asked, "Find the map."

When Bai Song turned to look at the map on Wang Liang's phone, he suddenly saw Huahua and Huahua staring at him with wide eyes, as if waiting for something.

So spiritual?

Bai Song was shocked. He seemed to be able to tell that the two dogs knew that the call he just made was to inquire about their owners!

Bai Song suddenly felt a sore nose. He got out of the car and sat in the second row. Finally, he reached out to touch the two dogs and said softly: "It's okay. Ji Yue, he's okay."

When Bai Song said it was okay, he subconsciously wanted to shake his head, but he was afraid that the dog would misunderstand something, so he froze his neck, then put on a smile, a very happy smile, and petted the dog, " Ji Yue, very good!”

After saying that, Bai Song gave a thumbs up. He believed that the dog could understand the word "Ji Yue".

The two dogs were instantly surprised, their tails wagging crazily.
