The sea gave the Penguin a dismount, and the frogman squad went into the water for the first time, and one of the fighters lost his life. Gu Yao's face sank like water, and after inquiring about the situation on the bottom of the sea, he immediately sent the second group of frogman teams into the water, and at the same time contacted Zhou Qingyu on the submarine to ask him about the underwater situation.

Submarines are also not allowed to dive to the bottom of the sea, and the two nuclear-powered attack submarines that are now following the Penguin can reach a maximum depth of 500 meters, which is still far from the bottom of the sea. It's just that submarines can be detected using special detection equipment sonar. It is said that this instrument was developed after being inspired by bats.

Sonar is the eye of the submarine, Gu Yao sent a group of frogman squads at sea, and Zhou Qingyu was not idle, leading the two submarines in a zigzag shape with the Penguin, and at the same time turned on the sonar to comprehensively detect the situation on the seabed and the surrounding area.

This detection is amazing, ten nautical miles northeast of the Penguin, there are two huge points of light, and there are also two points of light behind the Dawn, that is, the submarine that Zhou Qingyu is riding, these points of light represent ships and submarines respectively!

Zhou Qingyu clenched his fists, and as expected, there were many people who coveted the Flying Dragon. Judging by the number and layout, these ships and submarines should belong to different forces! Zhou Qingyu gave an order to the other submarine to be on guard and began to lead the Dawn to dive! With the current technology, the submarine cannot dive indefinitely, in fact, 500 meters is only a theoretical height, as the draft increases, the submarine makes a clicking sound, and it seems that in the next second, it will fall apart under the huge pressure of the sea.

When the Aurora reached 400 meters, it stopped. Begin to probe to the bottom of the sea. It is more difficult to detect the seabed, which is uneven, has trenches and even resembles the presence of hills.

A shipwreck, inconspicuous in this complex terrain. Even so, after a night of searching, Zhou Qingyu finally locked on a suspicious area.

After all, the density of rocks is not the same as that of metal, and it is also different on sonar, which requires frogmen to find out!

After receiving the direction reported by Zhou Qingyu, Gu Yao did not hesitate to put on the diving equipment that had been prepared a long time ago, and prepared to follow this group of frogmen into the water together.

Liu Bin has followed him for many years and knows that Gu Yao regards the honor of the country above all else, but the bottom of the sea is unfathomable, and with strong enemies around, Gu Yao personally went into the water, which is too risky!

"General Gu, you stay on the boat and let me take people down!" Liu Bin stopped in front of Gu Yao and said that he would not let him take the risk in person.

Gu Yao put on a diving mask, stretched out his hand to push Liu Bin away, and made a victory gesture at him, walked to the gangway, and jumped into the water first.

Gu Yao's diving technique is very good, arousing a small splash, at this time the dawn has come, under the illumination of the morning sun, you can see Gu Yao's figure quickly dived to the bottom.

Immediately, three frogman warriors jumped down, and for the sake of safety, everyone tried to work in groups of three or four people to take care of each other.

Gu Yao soon arrived at the designated direction, there were three frogman warriors following behind him, Gu Yao gestured, the first one began to dive, as the depth of the dive increased, the huge pressure of the sea water, as if to crush his body, at a place of fifteen hundred feet, Gu Yao stopped, began to adjust his breathing, ready to search.

Now it's completely dark underwater, and some unknown fish and seaweeds, emitting a faint fluorescence, look like the night sky!
