PS: There will be an update in the evening.

————

"Don't rejoice too soon, everyone, we still have many enemies."

Although Ling Han was also very happy, he quickly calmed down and shouted to all the crew.

The excitement of everyone quickly dissipated, and only one enemy was killed, and there seemed to be many opponents to face next.

"Torpedo compartments No. 1 and No. 3 reloaded."

"Bearing 140, two-thirds of the way at full speed, get out of this place."

Ling Han's gaze was on the navigation chart in front of him again, this time they only had four submarines operating in this area, and the speed of the enemy's submarines was most likely several times or even more than ten times that of them.

And just as they don't know the number of enemies, the enemy doesn't know the number of opponents they're up against.

It was a dance with death, and the victory of the second submarine was based more on the advantage of the first starter, the submarine sat on the bottom of the seabed, and there was no signal at all.

Even if an enemy submarine passes over the head of submarine No. 2, it is impossible to know that there is a submarine underneath.

This was a time to wait for the rabbit, Ling Han didn't dare to guarantee that there would be an enemy in this place, fortunately, the enemy appeared like this.

Before the arrival of the enemy, there were dolphins who received a message in advance, so the submarine was able to open the torpedo compartment before the enemy approached, avoiding turning on the mechanical sonar signal of the torpedo compartment, which was heard by the enemy.

This is to avoid the submarine being attacked by the enemy, and to be able to calmly attack the enemy.

And in order to be able to attack effectively, the two torpedoes fired were specially designed, the first torpedo was fired, the second torpedo followed, and it followed the first torpedo.

The sonar of the submarine has a blind spot, as if the submarine cannot hear the sound behind it, because the propeller noise behind the submarine will drown out all the sound.

The effect of listening to torpedoes is the same, the sonar signal of the second torpedo hidden behind the first torpedo is interfered with by the signal of the first torpedo.

In fact, if you listen attentively, you can still hear a little difference, but it takes a lot of experience to clearly hear that it is two torpedoes.

The attack tactics worked easily, the first torpedo was detonated by the enemy's torpedo, the second torpedo continued towards the enemy, and then destroyed the target.

This is not a clever tactic, and if it is left to the computer to listen to it, it is easy to confirm and distinguish.

In fact, during World War II, there was no such tactic of torpedo attack, and the enemy would not have decoy shells, let alone destroy torpedoes with torpedoes.

Although the results of the battle came out, from the first encounter, Ling Han felt an extraordinary aura, the enemy was also very powerful, at least in terms of torpedo and submarine technology, it would not be weaker than his own submarines.

"Set the depth of 50 meters, release the wireless communication cable, and send this advance report to the command center." Ling Han quickly sorted out his understanding of the enemy and handed it to the communicator.

As the submarine was advancing, the depth slowly rose, and soon it came to a depth of about fifty meters from the sea surface, and a slender antenna on the enclosure was released along the floating cable, and the floating cable brought out the antenna and rose to the surface.

As soon as the communication was connected, the correspondent received a telegram and sent it as soon as possible.

The submarine immediately retracted the communication antenna and dived quickly.

"This is a telegram from an hour ago." The correspondent handed the telegram to Ling Han.

The deputy captain walked over, saw Ling Han put down the telegram and asked, "What's the news?" ”

"Our helpers are coming, the three major anti-submarine destroyer fleets have arrived in the North Sea, but the sea surface is too windy and rough, and it is difficult for the anti-submarine fleet to provide us with comprehensive help at present." Ling Han said.

"It's damn weather, it's annoying." The deputy captain said with a depressed face.

"Get out of this place at full speed, let's go to the Bolick Trench." Ling Han ordered.

The Bolick Trench is a large undersea mountain jungle, the highest ground of this undersea mountain jungle is less than 50 meters above the sea surface, and it is high all over. Towering underwater stone forest.

These stone forests are all evolved from the movement of the earth's crust, and the highlands are different, and there are many trenches crisscrossed by kilometers deep, and there are many undercurrents on the seabed.

If it is a submarine of World War II, it will not be able to operate in this sea area at all, and even a modern submarine will not dare to enter this sea seamount group without a detailed chart.

However, the No. 2 submarine dared, because the goal of the No. 2 submarine here was to map this dangerous underwater peak.

In this underwater peak, there are actually many roads that can be moved, and the submarine current is turbulent, the peaks are lush, and the ocean background is higher than that of the submarine itself.

Three hours later, the No. 2 submarine did not encounter any danger along the way, and soon approached the entrance to the trench.

On the navigation drawings of the No. 2 submarine, there is a temporary survey of the trench, and the drawing has a zigzag course, which is the fastest route through this trench.

Outside the Brick Trench, at the bottom of the dark sea, a huge submarine is quietly lurking in front of this trench.

Submarine No. 2 did not notice its existence and even sailed in the waters less than three hundred meters in front of it.

The dormant submarine enclosure has the word crime written on it, and above the crime is spray-painted with the same pattern as the Goddess of Death.

In the Crime, they had long discovered the end of the No. 2 submarine, and they were all ready to attack, but when they saw that the submarine was actually heading straight in the direction of the trench, the captain of the Crime, called the man who was called the crime, decisively pressed the desire to attack. Hope.

He has full patience with his prey, not to mention that this prey may take him to understand the peaks of the sea in front of him, and he is willing to let the prey show his greatest value and then crush it.

Inside the Crime, all the sounds were muffled, not even the heartbeat was too noticeable.

As the No. 2 submarine passed, the captain waved his hand, and the parked crime began to move, following behind the No. 2 submarine.

The submarine could not hear the sonar signal behind its own submarine, so the people in the second submarine did not know that they were brushing shoulders with the Grim Reaper, and that the Grim Reaper was staring behind it.

This is a silent hunt, the Crime, which is a large circle larger than the No. 2 submarine, slowly followed up, and hung 1,500 meters after the No. 2 submarine, not that the Crime did not want to get close, but did not want to get involved in the other party's wake.

Following behind the submarine, although it can be stealthy, it is not too safe, and even both sides are in danger of crashing at any time.
