Night, always mysterious, will bring a lot of invisible darkness, but also bring a lot of mysterious beauty.

Kissed Li ruobai beside him. Jiang Yanhai crept up from the bed. With an advanced scanning program, he naturally didn't have to worry about waking Li ruobai.

Lightly closing the door, Jiang Yanhai went outside and sat down at the table.

"Two eggs." Jiang Yanhai called two eggs in his mind.

"Commander." the voice of two eggs rang.

"If one day you and I are gone, will your subroutine exist alone and continue to run?" Jiang Yanhai asked.

"The subroutine is an independent system that runs independently. It has the ability to run independently." Er Dan gave the answer directly.

"Copy a subroutine separately, set several rules for it, let it automatically encrypt all its files, and then close itself, but it will copy and hide itself on the network until the conditions I set are triggered, and then start running." Jiang Yanhai said directly.

"Yes, commander, the order has been recorded. What documents do you want to save?" Er Dan said very simply.

"I want to write a letter." Jiang Yanhai said seriously.

"I see."

……

More than an hour later, Jiang Yanhai crept back to the bed, carefully opened the quilt and lay on the bed.

Li ruobai, who was already asleep, clearly didn't wake up, but she seemed to be instinctively leaning towards Jiang Yanhai, and then next to him, she continued to sleep deeply.

He put his hand around her body, felt her temperature and smelled her smell. Jiang Yanhai soon went to sleep with a smile on his face.

……

"Captain!" a sudden voice suddenly woke Jiang Yanhai up.

With his eyes closed, Jiang Yanhai fiercely opened his eyes, and the familiar cabin structure around him suddenly appeared in his sight.

With countless experiences, Jiang Yanhai instantly understood what kind of state he was in.

Mirage simulation combat system!

This is the third time.

Oh, it shouldn't be the third time. Countless times have passed, or this should be the third scene.

This time... Looking at the silent flashing lights around, Jiang Yanhai instantly determined where he was located, submarine!

This silent warning light can only be used in submarines.

The surrounding environment was instantly printed into his eyes. He directly took down the hat hanging next to him. When he put his hat on, he glanced at the rank on his shoulder. Colonel!

According to the words just heard from the young submarine soldier in front of him, he has determined his identity, the captain of this unknown submarine!

The supreme commander of a submarine.

So for the third fantasy simulation battle, is he in the Navy? Or is it finally the Navy's turn? But in reality, do you still have a chance to play the Navy? Jiang Yanhai thought, it seems unlikely.

Even if he has that authority, it is estimated that he can't play.

But he is more concerned about what kind of technology he can get here?

Of course, this requires him to get through this environmental simulation battle.

"Don't panic, what's the situation?" countless thoughts turned in Jiang Yanhai's mind. It was just a moment when he wore a hat.

After putting on his hat, Jiang Yanhai stretched out his hand and patted the signal soldier.

"Captain, we have entered the security alert area. The sonar has just reported that we should have been watched," the signalman whispered.

"Go." Jiang Yanhai said quietly and immediately.

"Yes!" the signalman's voice was very low, although his tone was very firm.

All the officers and soldiers on the whole boat are constantly rushing out of their cabins and rushing to their posts quietly and quickly, which is completely different from the war state on the warship.

In the submarine, any action should be kept quiet. Sometimes the voice of speech may be captured by the enemy's sonar, especially when the sonar is becoming more and more abnormal.

If radar is playing on the sea and land, sonar and sound waves are playing in the sea.

Everything is determined by sound waves, because other detection effects are too poor in the depths of the ocean.

Jiang Yanhai went directly to the submarine bridge. Although he had not entered the submarine, he was still familiar with his actions, such as how to quickly pass through the water sealed hatch and so on.

These things, advanced scanning program can tell him.

"Captain!" when Jiang Yanhai entered the command cabin, a herald immediately whispered.

Everyone stood up directly from their position and stood at attention.

"Return and report."

"Our passive sonar has detected the enemy's search sonar signal. Now we are not sure whether the enemy has found us," the sonar soldier immediately reported.

The command cabin has been specially silenced. There is still no problem with normal speaking here, but the sound is different from others. What can be avoided should be avoided.

Jiang Yanhai went directly to his command position. There is an advanced electronic display screen here. Obviously, the advanced degree of this submarine is very high.

"Where are we now?" on the screen in front of Jiang Yanhai, there are relevant sea area maps and other information.

"According to intelligence, there is no enemy in No. 3 war zone. We should pass through No. 3 war zone safely, and then release the special forces through the torpedo launcher in A8 area." the information officer reported quickly.

"Depth." Jiang Yanhai didn't reply, but continued to ask.

"625 meters." a number that shocked Jiang Yanhai.

You know, in reality, the maximum submergence depth of nuclear submarines in various countries can rarely reach this submergence depth.

However, this depth has been advancing normally, which means that its ultimate diving depth is definitely not this depth. No submarine will advance at the ultimate diving depth.

"The current mode of promotion." Jiang Yanhai asked again.

"Normal propulsion." Jiang Yanhai's question will certainly not be asked by ordinary submarines, but he just guessed and asked one more question, but he got the answer.

He is already familiar with the fantasy simulation battle system, where he can play foolishly. Of course, if he is OK, he absolutely doesn't want to experience the feeling of death.

"Can we replace all electric propulsion?" Jiang Yanhai asked directly.

At present, the most common propulsion mode of ships is nothing more than heavy oil or nuclear reactor boiling water, and then the steam and gas turbine directly drives the propeller for propulsion, while the other is all electric propulsion. The power system directly burns water to generate electricity, and then the electric motor is directly driven by electricity to drive the propeller.
