Xu Youbing and the others began to land on the south shore of Nanya Island, which itself is a natural harbor, with the deepest underwater depth reaching a distance of thousands of meters, and can berth millions of tons of giant ships and even warships. This is an excellent military seaport, and the South Vietnamese State has invested a considerable part of its funds to build this small island that was snatched from the Huaxia State very well, as a port where they continue to grab the oil and gas resources in the Huaxia area.

The night was thick, and the sea was basking in the daytime fire-like sun for a whole day, and the temperature was very comfortable. Xu Youbing, wearing combat suits made of special stealth materials, swam forward quickly. From time to time, fish swim by, and the colorful tropical fish are very eye-catching. From time to time, gesturing with the other two girls, marveling at the beauty of the fish swimming here. If you catch a few and keep them in the fish tank, it must be particularly eye-catching.

But the further you go, the fewer and fewer such beautiful and colorful swimming fish, for the simple reason that there is a row of shark nets with barbs in front of you. In fact, this is an anti-shark net, but everyone knows that it is actually a defensive net to defend against sneak attackers. If it is a beach in China, it is not surprising that such fishing nets are placed a few hundred meters into the coastal bathing beach, which is specially set up to protect the safety of tourists and prevent sharks from swimming to the shore to bite. However, there are no barbs on the top of the domestic shark net, and the size of the net buckle is specially designed for sharks, and it is not as tight as the one in front of you.

And this defense net is obviously used to defend against sneak attacks, not only with barbs hanging on it, but also connected to an alarm device. Xu Youbing cautiously leaned on the defensive net. The design of these nets is very unique. Don't talk about people, it's just that some inadvertent fish touch it, and it will be hung by rows of barbs in an instant, and then the fishing net will quickly return to the cage, whether it is a swimming fish or a sneak attacker, it will be tightly wrapped in the defensive net, and can no longer move the slightest, can only sit obediently and wait for death.

In the case of a sneak attacker, it is even more terrifying, because the alarm device connected to the back of the defense network will immediately send an alarm to the command center, thus attracting frogmen to capture them alive.

The defensive net drifted with the current, followed by a dense network of various mines of different depths floating in the water. The corrugated radar rotated slowly, transmitting monitoring data to the water command center from time to time.

"Throw the sharks, if you don't disrupt their deployment, we won't be able to pass through this defensive network alone!" Xu Youbing gave the order to attack and harass Hai Yanzi.

Everyone quickly retreated, and the sea man very calmly pulled out a piece of lead in the belly of the shark in his hand. The shark's weight was suddenly reduced, and due to its buoyancy, it floated towards the shark net.

"Everyone, be careful, don't get too far away, stay two meters apart. Only by attracting frogmen can we see their stealth routes. If we swim hastily through it, this endless and bottomless defense network will exhaust our own physical strength. ”

The team members nodded one after another, the distance of the defense network is too large, if it is not surprising, I am afraid that there is a defense network in the entire coastline. In that case, even if you go around the island, you may not be able to find a breakthrough. Deep diving is even more unrealistic, because there is no professional diving equipment, and the problem of deep sea pressure alone can crush the fighters to rupture their abdomen and bleed to death. And if you want to cut off this very strong defense network, you will inevitably be unable to avoid the ripple radar. This kind of radar is very sensitive in underwater monitoring, and Xu Youbing doesn't want to go ashore for no reason. If you encounter the enemy when you land on the shore, it is quite a clear choice, not to mention the unwarranted physical exertion, and it may also attract a large number of enemies, resulting in combat attrition.

The team members were all holding their breath, Nanya Island was originally the land of China, and now it was occupied by people, not to mention that their own group of people came to carry out the mission, and they had to wait for the opportunity under the water so aggrieved, which was simply a shame for the soldiers. Luckily, the shark that was thrown out immediately caused the alarm to turn. This underwater alarm is silent, but it is a very eye-catching warning sign that turns on its own like an underwater gyro. In fact, he works closely with the corrugated radar, and when it issues a warning, the three-dimensional marine reconnaissance of the bellows lidar will quickly capture the warning target and automatically transmit it to the background for processing.

In order to attract the attention of the frog people, the sea man also put a t-shirt on the shark's body, so that from a distance, it looked like a sneak attacker was wrapped in the defense net.

The plan was very successful, and in a short time several speedboats sped up from the shore, and a few frogmen jumped down with a few pops. The guys quickly swam towards the defenses, cautiously approaching, and aimed their guns far away at the tightly wrapped shark.

"It's a sneak attacker, be careful, you pay attention to vigilance, and immediately observe if there are any other sneak attackers around!" a guy with a leader's appearance commanded several frogmen to pretend to be extremely cautious and leaned towards the shark. When he got closer, he found that it was actually a submarine shark hanging on!

But the strange thing is how this shark could have a T-shirt wrapped around it! Could it be that there really is a sneak attacker?

After carefully looking around, the frogs of South Vietnam vigilantly expanded the search area, but to their great disappointment, there was nothing unusual at the scene except for the shark that was tightly wrapped in the defense net, not to mention the infiltrators, not even the swimming fish.

With a "bang", another shark appeared a few meters away. The shark was clearly a dead fish, covered in blood and identical to the one hanging from the net. However, there was no t-shirt on his body, but he was scraped all over his body by the barbs on the defense net, and the largest wound on his body was in the abdomen, which could be more than a foot long, and the intestines of the fish were dragged outside, and it seemed that he had been dead for a long time.

"Pull down, quick, pull down! These abominable devils, they're the most nasty thing. Oh my God, these cruel guys, as soon as they show up, a swarm of sharks will quickly gather around! Quick, get me that dead fish from the defense net, get on the boat at once, and let us get out of this damn place and throw them far into the sea!"

The conductor roared loudly, quickly relaying his orders through the headset. Although Xu Youbing and his group were quietly lurking not far underwater, they could also estimate what he was talking about. As long as there is blood, there is blood, and more sharks will be quickly attracted in this water. Sharks are the most cruel fish in the ocean, they are the most terrifying bloodthirsty animals, and can be called the demon king of the ocean.

When they smell the smell of blood, they will quickly assemble, chasing the blood source in groups, the sharks stimulated by the blood, especially when they see the blood of their companions, the crazy sharks will even bite their own kind without scruples, as long as there are injuries, there is blood flowing out, they will be torn into countless small pieces by them in an instant, and then swallow in one bite.
