Fan Yize, who has given up on invading the Titanic world, doesn't care at all that his military power is discovered by this world.

It's a big deal to go back from the chrono portal and look for an opportunity to reappear.

But the enemy has to have a lot of concerns, there is no full-scale invasion of this world, it is obviously planned, in this case, the other party is in Min. Feeling the Baltic Sea, surface ships did not dare to appear casually.

In view of the fact that there are only four submarines that can be used at present, Fan Yize also hopes to increase the advantage of his own submarines through surface anti-submarine destroyers.

At the same time, at a depth of 100 meters at the bottom of the North Sea, a pitch-black submarine was slowly approaching the direction of the Skagerrak Strait.

The No. 2 submarine of the Red Alert Navy, with a total of 20 submarine officers and men in the submarine, is responsible for the piloting and operation of this submarine.

At this moment, the submarine is very quiet, because the enemy will be found again at any time, and this sea area is not safe.

The sonar listens to the non-commissioned officer, listening intently to the sonar signal.

"Captain, we have reached the place where the trail of the enemy submarine last disappeared."

Inside the operational headquarters, the combat adjutant said to the captain.

Under normal circumstances, the captain of a submarine is only a captain at most, but now that the submarine force has just been established, many senior officers have been trained in actual combat.

"Are there ships on the surface?" Ling Han asked.

"The water is very quiet, and there are no boats around."

"Calm up." Ling Han ordered.

The submarine began to release the water stored in the water tank, and the diving depth gradually increased, and the submarine remained balanced during the ascent.

A minute later, on the uneven surface of the North Sea, white blisters rolled on the surface of the water, and the huge submarine hull slowly surfaced, and then the entire submarine appeared on the undulating sea.

The watertight hatch of the submarine enclosure opened, and Ling Han was the first to climb onto the top of the submarine enclosure, taking out his binoculars and looking at the surrounding sea.

A light rain was falling in the sky, and a biting chill could be felt on the cold sea.

Several observers all appeared on the enclosure, one with one telescope looking at the surrounding sea.

"Look carefully and see if you can find the unmanned mapping machine released by the enemy." The submarine was slowly moving on the surface, and Ling Han ordered everyone on the enclosure.

At this moment, the communication soldier also climbed up, handed a translated telegram to Ling Han, took the order, Ling Han quickly glanced at the content of the order, and said to the deputy captain beside him: "The combat order has been issued above, destroy all underwater ships." ”

"We shouldn't have let that submarine go just now." The deputy captain is also a young man, with the rank of captain, and in the future he will definitely be able to stand alone and become the supreme commander of a submarine.

"Don't worry, I have a hunch that a brutal battle will come soon." Ling Han said.

"I hope the opponent isn't too strong." The co-captain spoke.

"We are not weak, and the winner is still unknown." Ling Han said.

"Report, direction 285, six hundred meters above the water, there is a floating object." An observer on the side reported.

Ling Han grabbed the telescope and looked at it, in the reported direction and distance, there was indeed a long mechanical load in the undulating waves, sailing on the sea surface under the undulations of the sea.

A small navigational mapping device powered by wind and wave machinery, which is able to map ocean information and then transmit it back.

"Everybody go down and dive." Seeing this, Ling Han immediately gave an order.

The people on the enclosure quickly slid down the stairs one by one, Ling Han was the last to leave the enclosure, locked the gate on the enclosure, and the submarine began to descend, and soon disappeared into the sea.

"The depth of the dive is two hundred meters, the bow is fifteen degrees, the stern is five degrees, the azimuth is 165, and the speed is twenty knots."

When the co-captain heard the order, he immediately asked, "Did you leave like this?" ”

Ling Han lightly pointed at the map and said, "Let's go to this place, sit and sink at the bottom of the sea, and wait for the enemy to appear. ”

"I hope that our dolphins will be able to transmit the enemy's location information faster." The co-captain nodded.

"How many dolphins are in action in this area?" Ling Han asked.

"There are only three dolphins, and the rest of the dolphins are currently mapping the seabed, not in this area."

"Three dolphins, that's enough, use sonar whispering to inform the dolphins and let them move around us." Ling Han said.

The sonar soldier who received the order immediately rhythmically controlled the frequency of the active sonar, and the three dolphins moving around began to change direction and approach the No. 2 submarine when they received the sonar signal.

Two hours later, the submarine arrived at the bottom of the pre-ambushed seabed, the first sea bed ever explored, at a depth of 180 meters, with no rocks on the bottom and layers of mud.

The submarine slowly landed on the seabed, and the speed was very slow, until the light touch came, the submarine power system was completely shut down, and it landed safely on the seabed.

"Eat, rest, and get ready for battle." Ling Han took off his military hat and ordered.

In the galley of the submarine, dinner was almost ready, with delicious steaks, grilled lamb chops, vegetables, fruits, milk and fruits, as well as tea and coffee.

The hard life of a submarine, and most preciously, enjoy the delicious food.

Although the power of the submarine is very valuable, in order to make the officers and soldiers in the submarine live a better life, a freezer storage room is also prepared, otherwise any food in the wet submarine will quickly become moldy.

The interior space of the Anonymous-class submarine is relatively large compared to only twenty crew members, but it is not luxurious enough to have a separate dining space.

The crew also ate in the rest cabin, with beds on both sides, five sections on the left and right, and ten beds on each side, and the aisle in the middle spread out to be the dining table.

Inside the submarine, the greatest pleasure is to chat and eat together, or play cards to pass the time.

A sumptuous dinner, with fragrant rice and toast, everyone was quite comfortable.

On duty on duty, sleep on sleep, a. The night passed quickly, and in the early hours of the next morning, red lights began to flicker inside the submarine, and the sleeping crew was awakened.

"Combat alert."

The awakened crew quickly rushed to their combat post, the torpedo compartment was filled with water, pressurized, and the torpedo operation soldiers were ready to open the external closure of the torpedo tube.

In the command headquarters, the sonar adjutant translated the sonar information from the dolphins, and found an underwater target approaching at the bottom of the sea, 50,000 meters away from the submarine.

"Activate the torpedo, open the torpedo hatch, and prepare to lock on to the target." Ling Han gave the order to attack.
