If the three geologists were correct, the two ministers would have been in the building at all times before the flood.

Then there are only two reasons for their disappearance:

One is to be swept away by the flood in a panic, so that the only way to do this is to wait for the flood water to recede and look for the body in the downstream accumulation area;

The other is to escape downward, and as a result, like the three geological technicians, they are trapped in the building, and from the descriptions of the three people, it is estimated that there are many staff members in the building.

So Gu Ji prepared for underwater diving search and rescue.

But Fatima frowned.

"Vidi, even if the chief minister and the accompanying secretary don't understand anything, will the minister of water resources not understand the relevant knowledge such as flood evacuation and self-rescue?"

"That's not a possibility, and we're not all looking for two ministers."

Gu Ji shrugged his shoulders and immediately commanded the fleet to approach the building.

The height of the high-voltage 500KV power pole is at least 12 meters or more, and three government officials are holding on to it, indicating that the water level has exceeded 10 meters.

In fact, the third floor of the building was indeed submerged by a small half.

In order to prevent accidents, he first tied a safety rope to his body, then replaced the rope sleeve at the top of the rescue telescopic rod with an iron hook, smashed the glass, hooked the edge of the window frame, and confirmed that it was stable.

This is supposed to be a leader's office, and the water probably doesn't reach the calf.

Pushing open the door, Gu Ji fixed the safety rope on the fire hydrant in the corridor, and glanced at the building's fire building structure diagram by the way, until the rope was dropped, Fatima and eight or nine rescuers climbed in one by one with the equipment on their backs.

"Fatima, you take someone to see the conference room, and report any problems at any time; Singh, you guys come with your equipment to the central staircase! ”

"Yes!"

Several people should shout, and the detachment should move.

Gu Ji leaned against the wall, slowly came to the corner, and reminded the three of Singh, because the water has submerged the building, so on the surface, the water in the corridor and the water in the stairwell are the same plane, but if you are not careful, take one more step, you will fall into the water and knock into the stairs.

"Wetsuits, walkie-talkies, sonar detection."

Gu Ji waved his hand and asked the rescuers behind him to take out all the equipment.

The so-called underwater diving rescue technology refers to the fact that rescuers first detect and determine the location of people, vehicles, and important items in the water through various scientific and technological means, and then divers enter the water to carry out underwater objects and personnel salvage.

Because the natural waters are often not as clear as artificial pools, the environment is very complex, in addition to the turbidity of the water, there are various undercurrents, reefs, aquatic plants, cracks, etc., which can be injured at least and stranded at worst.

Therefore, in order to ensure safety, before underwater diving and rescue, the water area must be explored, such as ROV underwater robots, sonar detection and other high-precision rescue equipment.

Platan equipped the 14th detachment with a multi-beam sonar detector, powered by a mobile power supply, with a sonar frequency of 720KHz, equipped with a wireless detector, built-in GPS, a wireless connection distance of up to 100 meters, and a scanning depth of up to 80 meters.

Gu Ji quickly took off his waterproof rescue jacket, changed into a self-brought diving suit, and brought bone conduction headphones, safety ropes, and underwater demolition tools.

On the other side, the rescue technician also completed the commissioning of the sonar equipment.

When the acoustic signal is transmitted in the water, if it encounters a target such as a person or a wall in the water, it will be reflected back, and then it will be turned into an electrical signal through the transducer.

He first connected the detector with a fishing line, lowered it little by little, and after starting, a horizontal scrolling pattern like a three-dimensional map appeared at the bottom of the color screen, and the picture showed blue, yellow, green and other colors, which are the colors of the sonar echo image, which was gradually transformed into a three-dimensional image after being reconstructed by the chip algorithm.

Gu Ji took the screen and glanced at it twice, the screen was very blurry, just like a 3D modeling apprentice who had just started, and there were many miscellaneous spots in the space, which should be mud blocks in the water, magazines and the like, but fortunately, after he saw the fire building drawings of the building and corresponded to the walls one by one, he gradually had a bottom in his heart.

So I put on a breathing mask and a flashlight.

"Ready, three, two, one! Let's go! ”

Crash!

Different from the general rescue divers, Gu Ji's action range is very small, and even the sound is very small, after entering the water, he first feels that his body is wrapped in a warm and cool feeling, the front of the mask is cloudy, and the visibility is only less than half a meter, his feet swing slightly, continue to go down, at this time the ears will feel uncomfortable like taking an airplane, which is caused by the change of pressure in the ear cavity caused by water pressure, as long as you do more swallowing and breath-holding actions can be quickly relieved.

As soon as he swallowed, the voice of the third-floor sonar detector came from the bone conduction headphones:

"Be careful, there's a large object approaching on your right, and the system determines it's a human!"

Due to the delay in sonar detection, when the detective finished saying this, a black shadow had already appeared in front of Gu Ji and Singh, and when they were close to about half a meter, the two saw an Indian man with pale skin.

Since more than four hours have passed, his body has been a little swollen and deformed, especially the skin of his hands and feet is completely wrinkled, like a drifting woman's skin, and his facial features are even more terrifying, the two eyeballs are protruding outward, and the cheeks are bulging, as if they are about to burst from the body.

Gu had seen this kind of scene with his own eyes in the underground building level, so he was only slightly stunned, then raised his hand to push the corpse away, and then gestured to the left and right sides with a flashlight: "Singh, go to the left, focus on exploring the room with the door closed!" ”

"Good, Commander!"

Singh nodded, but noticed that when Gu Ji left, the swimming movement was very slow and the amplitude was also very small, completely using the power of the flipper swing to "slide" forward, and he recalled Gu Ji's appearance when he entered the water just now, the whole process did not look like a rescue, but like a "secret invasion".

In fact, this was Gu Ji's combat instinct after gaining the skill of close combat in sea operations.

In the tactical diving of special forces and SWAT teams, it is often necessary to perform extremely difficult tasks, such as diving infiltration, underwater blasting, etc., which requires carrying a large number of professional equipment: front-mounted closed breathing apparatus, buoyancy vests, underwater communications, diving compasses, counterweight belts, individual sonars, etc.

Such a set of well-equipped divers is very slow underwater, only 3-5 km / h, because a long swimming will make people tired, too far will use underwater transport submarines and other vehicles, so "saving physical strength" is very important for tactical diving.

According to the sonar instructions of the detector.

Gu Ji directly skimmed the first room, because the open room meant that it was already filled with water, unless there was a need for diving equipment, it was impossible to live underwater for more than four hours, only the room with the door closed, and it was possible to barely survive on the only remaining air like a train.

"Commander, the door to the fourth room on the left is closed!"

"I also found the third closed room on the right, first check the bottom door crack to see if there is any covering, and use a flashlight or hammer the door to transmit a signal to the house."

Gu Ji said as he began to approach the door frame and checked the crack in the door with a strong flashlight.

If there were people inside, they would definitely use clothing, foam and other items to find a way to plug any leaks, and sure enough, when he looked at the bottom, he found that the crack in the door was a finger's width and someone had stuffed plastic bags inside.

"Singh, I've found something here!"

After Gu Ji shouted, he knocked on the door hard, and after a few consecutive sounds, there was a sudden response of "knock knock" inside, and then Singh also swam over, "Pry the door first." ”

As he spoke, he pulled out the underwater demolition tool from behind his back.

It is composed of a shear, expander, ejector and high-temperature cutter, which can realize shearing, expansion, jacking, cutting and other demolition operations on land and underwater.

Gu Ji first inserted the dilator into the crack of the door, twisted the lever, and with a force, the door frame holder was instantly loosened.

At this moment, there was a sharp and violent knock on the door of the house, and needless to say, there must have been water leaking in.

"Three, two, one, prepare to break down the door and rescue!"

He deliberately gave several people in the room a reaction time, and after giving Singh the order, the two continued to dig the demolition tool deep into the widening crack in the door, stepping on the wall with their right foot, and at the same time pulling it outward.

Click!

The upper part of the door was instantly opened with a huge crack, and with Gu Ji's continuous efforts, the door completely broke away from the broken door frame, and the stagnant water also poured into the house, and in the blink of an eye, the house was submerged.

"Commander! The sonar shows that there are three people in the room! ”

"Singh, you bring one, and give me the other two! Go back the way you came, I'm first! ”

Gu Ji decisively assigned the task, while using a strong flashlight to attract, he swam into the house, and when he turned his head, he saw two black shadows approaching him, he didn't have time to pay attention to the other person, because that was Singh's task, under the premise of not knowing the water nature of the three people and the oxygen content in the lungs, all he could do was to race against time to bring people out of the water.

So Gu Jiyi grabbed the waists of the two of them, like carrying chickens, shook his flippers, and quickly swam towards the central stairwell.

And the two of them also seemed to understand that someone was saving themselves, and honestly hugged his waist.

At this moment, it reflected the benefits of Gu Ji's previous saving of physical strength underwater, coupled with the improvement brought by the endurance mark, even if he carried two trapped victims, his speed was still not affected.

Whoa——!

A splash suddenly appeared in the water on the third floor, and Gu Jicheng surfaced with two victims.

"Quick! Hand on! ”

"Watch out for stairs!"

Seeing the rescuers hurriedly surrounding, Gu Ji hurriedly took off his breathing mask and shouted, while not forgetting to care about Singh underwater: "Singh! How's it going on your end? Answer quickly! ”

"Whoa! Commander, I've brought people in! ”

As soon as he finished speaking, Singh and another victim appeared behind him.

After the three were pulled to the windowsill and sat down, the accompanying medical emergency personnel hurriedly checked whether the three were injured, perhaps because of the four-hour darkness that left them with a deep shadow, even after being rescued, several people still stared at the water on the ground with their eyes and feet shrunk, looking at the water on the ground in horror.

"Don't worry, you are saved now, and I will arrange for someone to send you safely to the disaster shelter, but I still need to ask you a few questions, are there any other people trapped in this building, and in addition, have you seen the chief and the two ministers of water conservancy?"

In the face of Gu Ji's question, one of the female government workers with long brown hair shook her head, took two deep breaths, and forcibly suppressed the panic in her heart and said: "There should be more than a dozen people, soon after the flood flooded, we heard a lot of screams, and when we reacted and wanted to escape, the water had reached the second floor, the door was difficult to open, and the water kept pouring in from the crack in the door...... We don't know, we just know that the Chief Minister is in the conference room! ”

"Singh, you take the people away first, and then two divers will go down with me."

"Commander, you should also take a break, after all, you are swimming up with two people!"

"Rest assured, this little bit of work won't drain my physical strength."

Gu shook his hand and put on the oxygen mask again.

Singh gasped slightly, seeing that he was indeed breathing steadily, and then left with three staff members through the window with safety ropes.

That's it, under the command of Gu Ji.

The 14th team swept the entire building of the Geological Monitoring Department and rescued a total of 11 people, one of whom was a well-known geological survey expert in Assam.

Fatima rummaged through all the rooms on the third floor of the building, including the conference room, and found no valuable clues.

"It seems that they may have been swept away by the flood, no matter what, let's get out of here first and move on to the next target point......

The minister is important, but Gu Ji can't always revolve around them.

Just as he turned to retreat, he happened to catch a glimpse of the geological surveyor, who seemed to be in his forties, silver-haired, with black-rimmed glasses, dark brown skin, and dressed in a white trigram, typical of Indian scholars.

During the rescue conversation, Gu Ji already knew his name.

"Professor Nandeo, do you have anything to say?"

"I ......"

Nandeo hesitated for a moment, but finally made up his mind: "I don't know if it's appropriate to say this, before the flood, the chief minister once approached me to ask about the geological activity of the Himalayas, when I heard him and the minister of water resources outside the door seem to have a big quarrel, the emotions of both sides were very excited, the accompanying secretary asked me to leave for a while, and come back later, who knows, the disaster happened immediately after......"

Did the two also have an argument?

Gu Ji and Fatima glanced at each other and couldn't help but raise their eyebrows.
