Gu Kun woke up in his sleep, and when Yu Yue ran to the door of the terrace, he had already seen the sea water surging in.

He hastily thought that the levee surrounding the sea had burst, but this description was actually very inaccurate.

Because anywhere in the Netherlands there is more than one embankment enclosing the sea, it is impossible for them all to collapse at once. What Gu Kun saw was only a small collapse in the outermost ring of the warning embankment.

The reason why it is designed is to gain buffer time in case of an accident, so that it is convenient to rush to repair or lose the car to arrange flood discharge.

This is the experience of the Dutch who have been submerged for hundreds of years.

The Hague, where he now lives, belongs to South Holland, and the terrain is relatively high, so the early warning embankment is not too complicated.

If you go to the lower North Holland, in order to prevent the embankment from being unable to withstand the water pressure, there are even layers of embankments to build artificial lakes to buffer. That is to say, the inner side of the outermost embankment is not land, but the inner and outer sides of the embankment are water. It's just that the outer water level is high, and it's the sea, and the inner water level is low, it's the lake.

For example, the famous causeway between the Wadden Sea and IJsselmeersee, which stretches for dozens of kilometers, is the sea to the north and the lake to the south. From the sea to the land, there are several layers of lakes and embankments.

In fact, even if people who have never been to the Netherlands imagine it in their hearts, they know that this kind of preparation is not too much - ordinary people buy a high-rise apartment, if it is a glass curtain wall and floor-to-ceiling windows, they must ensure that it is double-layer laminated tempered glass to have a sense of security.

No matter how hard a single glazing is, residents will feel unsafe. (In the eyes of victimization paranoia, both layers are not necessarily safe, maybe they will be drilled by Jason Statham)

However, since it was just a warning that there was a breach in the embankment, why did it flood the villa-style hotel where Gu Kun lived?

This is going to talk about the selling point of his hotel - because it is a hotel with a sea view, so for the view and view, the house is built between the main embankment and the warning embankment, this kind of planning is also legal in the Netherlands, but in case of extreme weather, countries will mandate evacuation.

The house shared by those who hate the rich on Douyin in later generations will be hit by the waves on a stormy day, and by the way, add a comment "That's why I don't buy a house with a sea view", which is roughly like that.

If you choose this kind of place to live, you have to take the risk.

At the same time, there are partitions between the buildings on the early warning embankment, and the waterproof height of the partition is about one or two meters, so even if one point is flooded, the other points can also slow down the damage rate.

……

Seeing that the water was about to overflow to the second floor where he slept, Gu Kun couldn't care so much.

He didn't even wear a coat, but quickly stuffed the important things around him into a waterproof suitcase, locked them in the safe in his room, and then prepared to jump into the water and swim to the main embankment inside.

However, at the moment when he put things away, he looked back and saw a scene that made him change his mind.

Under the moonlight, there was actually an assault boat that burst through the gap in the early warning embankment with a small drop in the water level and rushed in.

The people on the boat were pitch black, and they couldn't tell the difference.

Gu Kun hurriedly picked up a Magnum revolver, didn't bring anything else, and jumped directly into the water.

As soon as he jumped into the water, he saw Gao Jianxiong next door also follow and jump into the water.

There were still four bodyguards living on the first floor, and Gu Kun heard a noise before jumping into the water, some rushed upstairs to check on the boss, and some swam out of the window directly, and there was a lot of chaos.

The floor where ordinary bodyguards live is lower, and it is estimated that they have already been flooded by the time they wake up, and these people are trained by the army, so they have only been bodyguards for a long time, and they cannot be asked to do more in a panic.

"Boss, are you okay?" Gao Jianxiong hurriedly swam to Gu Kun's side, first to make sure that the boss had any problems, and he didn't care about his subordinates.

"I'm fine. Gu Kun only had one head exposed on the water, and replied in a low voice.

At this time, he heard a bodyguard who had climbed onto the roof of the attic of the villa-style hotel, shouting to find Gu Kun while looking.

"Don't be nervous, the boss is fine!" Gao Jianxiong was afraid that the other party would not be able to find the boss to worry about, so he spoke out to stabilize the morale of the army.

"Don't shout!" Gu Kun admonished in a low voice, but in a stern tone. Then he couldn't care so much, and dived away directly, leaving Gao Jianxiong's position just now.

He didn't hear a "poof" in the distance, and the bodyguard who was standing on the roof to avoid the water was shot by an underwater gun ammunition like a crossbow arrow, and "poof" was planted in the water.

Then the people on the assault boat rushed straight to the direction where Gao Jianxiong shouted just now.

Gao Jianxiong noticed the assault boat, and when he saw that the situation was wrong, he finally realized that this was definitely not an accident, so he hurriedly plunged down and dived to escape.

However, he still had a brain, and he had already reacted to Gu Kun's intention to let him not make a noise just now, so he swam in the opposite direction to Gu Kun, so as not to expose the boss's position after being caught up.

After Gao Jianxiong disappeared from the water, two frogmen also jumped down from the assault boat, holding Soviet-made underwater guns that fired arrow-shaped bullets.

Gao Jianxiong does not have frog webs, so he is naturally not as flexible as frogmen underwater.

He didn't forget to pick up a gun in a hurry, so he had a Colt pistol in his hand.

In the dark night underwater, he can only rely on the perception of the current to fight with the other party, and shoot when he senses danger.

Ordinary firearms can actually be shot underwater, because the firing mechanism of modern firearms and the primer principle of bullets are not afraid of immersion in water.

The biggest problem with underwater guns is that the pistol bullet stalls due to the resistance of the water current, and it is basically lethal when shot two or three meters away.

In addition, automatic firearms require normal air pressure to cooperate with the air conduction shell to complete the loading, so American automatic rifles such as M16 can basically only shoot the first shot, and AK, which is a little rougher, will only get stuck after a few rounds.

In the case of pistols, because they are single-shot or semi-automatic, the underwater pressure difference jamming is better than that of automatic firearms.

Gao Jianxiong resisted again and again, after Colt shot three or four bullets, he finally encountered the pressure difference jam, he didn't know if he had hit the enemy's frogman, maybe he had bruises, but even if he hit more than three meters, he would have skin injuries, so that the other party would suffer pain and delay his action.

And his resistance, on the contrary, more and more exposed his position. Water conducts sound much faster than air, and the muffled sound of underwater shooting makes it easy for enemy frogmen to hear and identify their position.

Soon, Gao Jianxiong heard the muffled sound of the counterattackers' gunshots, felt something swishing around him, and finally was pierced in the arm by something in the shape of a nail, which hurt his heart.

It was a special bullet for underwater guns with a caliber of only a few millimeters, but a length of more than a dozen centimeters.

This kind of ammunition with large mass and small muzzle velocity has a much smaller effect of being reduced by resistance under water than light ammunition, and can kill and injure people at a distance of 20 meters underwater under the best circumstances.

"Special brew, do you want to explain in this kind of place today, I don't know if the boss has run away. ”

Just when his consciousness was slightly confused, he heard several more gunshots in the water, the sound of ordinary firearms, not special guns underwater. The offensive pressure on his side also suddenly decreased.

Gao Jianxiong didn't bring an underwater breathing apparatus, and it was definitely not possible to fight a protracted battle with the frogman, so he hurriedly endured the pain and diverted more than ten meters before changing his breath slightly, and quickly dived down again after the change.

And the assault boat on the water was immediately attracted to it.
