This text message, Bai Song stared at it for several seconds before he determined that the sender was indeed the sender:

Dad!

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

Daddy is actually here!!

Bai Song looked at the text message, stunned and speechless.

"Feng, has entered his home, not on a speedboat. Delete it immediately after reading. ”

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

"Captain Bai, Captain Bai?" Team Liu hurriedly asked several times, and Bai Song came back to his senses.

"Oh oh oh, I'm distracted..."In just a few dozen seconds, dozens of thoughts had flashed through Bai Song's mind, but he still hadn't recovered from the shock. These thirteen words, the amount of information is so large, that he feels that his brain is buzzing.

"The clue you just said?" Team Liu was a little anxious, but still lowered his voice, for fear of disturbing Bai Song's speculation, if it weren't for Bai Song's fact that he was ten years older than his son, he almost blurted out "you".

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

"I measured it when the divers went into the water just now, and now it's about 1.5 meters per second. Team Liu said directly, and did not ask Bai Song why he asked.

"The speed of one meter and a half per second, the equivalent speed is 5.4 kilometers per hour, and the speed of the flow is almost equal to 3 knots, according to the maximum speed of a small civil submarine of 10 knots, the actual speed of the countercurrent is almost 7 knots, that is, the speed is about 13 kilometers per hour, from the helicopter just found the problem, to now, 35 minutes should have passed, that is, the distance of the countercurrent is about seven or eight kilometers", Bai Song deduced to himself: " If the maximum speed of a small civilian submarine is estimated to be no more than 15 knots and not less than 8 knots, then the range should be about 4 km to 12 km upstream. ”

Before Team Liu could finish speaking, Bai Song continued: "If it is downstream, this range should be in the distance of eleven to eighteen kilometers downstream...

The upstream is closer to Hetan City, and the downstream is closer to Changhe City, according to the clue that the starting point for Zheng Can's transportation money is in Changhe City, the biggest probability is that the submarine went downstream, and the speedboat should be a cover, mainly used for pathfinding and attraction, once the water patrol ships are found, the speedboat has enough maneuvering power to lure away the ships that may have sonar.

Therefore, Team Liu, shrinking its strength, took out more than half of its strength, and concentrated on searching the section of the river 10 kilometers to 20 kilometers downstream from where the divers dived, searching for whether there were buildings in Hanoi, and increasing the investigation on both sides of the river. ”

"What?" Team Liu listened to Bai Song talking to himself for a long time, stunned and at a loss, just talking, how did he start to calculate the fifth-grade application questions... A few days ago, my son just tested him with these questions...

After a few seconds, Team Liu said, "You mean, I'm sure there is a submarine, and it's going to stop at the distance you said downstream, right?"

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

"White team", Team Liu called his position, "The on-site command will soon be handed over to the leadership of the Changhe City Bureau, I will report your plan now, can you tell me, where did you get your intelligence clues?"

"You can trust me. Bai Song turned his head to look at Huahua and Huahua, "If you have any questions, I'll take care of them." ”

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

...

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

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

It's easy to say anything else, but what Bai Song is most concerned about is Ji Yue's situation.

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

"I entered the rescue room, and a nail was inserted into the intestine from the back, and the other two were fine, but one almost entered the ventricle..."Wang Huadong said: "However, the doctor said that Ji Yue's life is really big, and he was sent over early." ”

Bai Song breathed a sigh of relief and relaxed a little, although Ji Yue was not out of danger yet, but this situation was basically fine, as long as the doctor said so, it would be fine.

Even if the bullet has a penetrating wound to the intestine, it is a big deal to amputate a piece, as long as it does not affect the main organs and a large area of infection, everything is okay.

When listening to others talk about the condition, the words "but" and "but" are useful, the better the first one, the second "but", it is also useless.

The three problems that Bai Song is most worried about, the disorder caused by the injury to important organs, the poison of nails, and the entry of foreign bodies have not appeared, which is really a blessing in misfortune.

How important is Ji Yue's block?

If there is no Ji Yue's blocking, a few centimeters of nails will be fatal for the dog, and once the dog is dead, if you want to find this underground structure, you have to rely on other dogs or related metal detectors, or you need to interrogate.

It takes at least half an hour.

Moreover, if it weren't for Ji Yue's injury, there would have been no matter of helicopters, let alone the discovery of speedboats, and this case could not be delayed.

After all the efforts, the timeline was finally caught up, and Bai Yulong's text message made the clue that had been left behind for half an hour be chased back.

The most important thing in intelligence is timeliness, authenticity and effectiveness. The latter two can often be obtained through hard work, but it often takes luck to obtain time-sensitive information.

What is my father doing?

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

"We're close here 10-20 kilometers downstream, let's go to this side, 15 kilometers and wait," Bai Song asked, "find out the map." ”

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

Is it so spiritual?

Bai Song was shocked, he seemed to be able to tell that the two dogs knew that the phone call he had just made was asking about their owners!

Bai Song suddenly had a sour nose, got out of the car, sat in the second row, and finally reached out and touched the two dogs, and said softly: "It's okay, Ji Yue is okay." ”

When Bai Song said that it was okay, he subconsciously wanted to shake his head, but he was afraid of being misunderstood by the dog, so he froze his neck suddenly, and then put on a smile, a very happy smile, and touched the dog, "Ji Yue, very good!"

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

The two dogs were pleasantly surprised, their tails wagging wildly.
