Although it is an unmanned submarine, this thing is for testing after all, and the ship still retains facilities for personnel to live in.

After all, it is still unknown whether AI can replace crew members. If there is any deviation at that time, it can be replaced by manual operations, which is not a waste of this expensive submarine.

Everything was as expected by the Federal Army. The chain dropped off on the first voyage. Moreover, the chain dropped a little too large, and the entire ship was simply lost.

Because this thing was made so advanced, the Federal Army searched several times but failed to find it, and in the end it had to be left alone.

Anyway, there are no nuclear bombs installed on the submarine, so if you lose them, just throw them away.

It is said that after that, no one in the Federal Army would pay attention to fighting unmanned submarines. At least Yin Yu has not seen any news of building unmanned submarines online in recent years.

"Although this submarine is 10 years old, it is still the most advanced submarine at present, so there is no need to worry about safety."

On the way to the command room, Chizuru kept introducing the submarine to Yina.

"Wait, 10 years?"

Yin Yu reacted very quickly and immediately discovered unusual information.

"Well, I got this ship when I was seven years old, and I haven't used it much since."

When he said this, Qianzu's face was filled with pride.

Yinyu's expression suddenly became strange. If the senior executives of the Federal Army discovered that one day the nuclear submarine was stolen by a seven-year-old girl, I wonder what they would think then?

Under Chizuru's leadership, the two soon arrived at the ship's command room.

The command room was empty, with only a holographic projector. However, after Qianzu activated it, a large number of pictures instantly filled the entire room.

This is the qualities that a warship in the 22nd century should have! In Yinyu's opinion, this place is almost the same as the command tower of the starship in science fiction novels.

On one of the screens, the current news is played.

Qianhe waved his hand gently and enlarged the screen a lot.

"Around 11:00 this morning, someone illegally used flights in the city of London, and the suspect has been arrested..."

Before the host could finish his words, Qianhe waved his hand again and threw the projected screen to some extent.

"The more technology develops, the more people feel that society is more open and free, but the facts... are exactly the opposite of this."

Qianzu's face was full of mockery, and his eyes were full of disdain.

“If it weren’t for the fact that we created a sonic boom at low altitude during the day, the news wouldn’t have reported these things at all.”

When an object runs at a speed of sound, it will encounter a strong resistance, causing the object to oscillate strongly and eventually lead to speed attenuation. This phenomenon is commonly known as Sound Barrier.

When breaking through the sound barrier, due to the compression of the air by the object itself, the shock wave surface is gradually formed on the windward area of ​​the object, and the acoustic energy is highly concentrated on the shock wave surface.

When these energy is transmitted to people's ears, people will feel a brief and extremely strong explosion, called a sonic boom.

The energy of the sonic boom is very high. The sonic boom generated by the fighter when flying at low altitude is enough to shatter the doors and windows. In a sense, the two of them died a great death before.

"That, Chizuru." Yinyu hesitated for a while before continuing, "I just left like this, will the people around me be in danger?"

"No." Qianzu's answer was quite yes. "That guy is still shameless and can't do such a thing."

"That's how it is."

Yinyu nodded, agreeing with Chizuki's statement.

She and Su Baiyu have also had a few deals, and this guy does not look like someone who can do such things.

"But you can't be careless because of this. Even if she doesn't use such despicable means, there are still many ways to deal with us."

"Um……"

Not using despicable tricks does not mean that the guy is a good person.

"After that being said, are we just staying on the submarine from now on?" Yinyu tilted her head.

People will go crazy if they stay in a closed space for a long time, which is also the reason why many submarines have two groups of members.

If I really want to stay here forever in the future, Yinyu feels that she might not be able to bear that day.

As if he had heard the concerns in Yinyu's words, Chizuru explained with a smile on his face.

"Of course we can't hide like this. Now we are just avoiding the edge."

"What after that?" Yinyu continued to ask.

"After that? Of course, we will kill that guy Su Baiyu. Only by solving her can we be free from this cycle of reincarnation."

Qianhe's voice was full of murderous intent, and I don't know what she encountered back then, which made Qianhe hate Su Baiyu so much.

"Can she be killed really..."

Although she didn't want to attack Qianhe, the impression Su Baiyu left on Yinyu was too deep.

"Even if that guy is a god, I will still kill you..."

After saying this, Qianzu coughed again.

"Are you okay?"

Yinyu grabbed Qianzu's hand, her face full of concern.

"I have to treat my injuries first. My body is still too fragile in this life." Qianhe took a few breaths, and then said reluctantly: "I will leave the 'Deep Sea Fortress' to you during this period. I have to rest for a while."

"The body is the most important." Yin Yu nodded.

...

Qianzu's injuries were far beyond Yin Yu's imagination. Although he could not understand the data on the instrument, Yin Yu could still know the seriousness of the matter from various warning symbols.

It's really a shame that guy Su Baiyu is so good at it...

In the 21st century, this is almost a mortal injury. Fortunately, the medical facilities on the ship are all high-tech in the 22nd century.

According to Chizuki's instructions and the notes on the instructions, Yinyu threw her into the glass pillar and poured it into it with the medicine that was said to be able to prolong her life.

After all this is done, a countdown appears on the display at the top of the tank.

If Yinyu is not mistaken, this should be the countdown to Chizuru's recovery. As long as Yinyu waits for the previous week as mentioned above, Chizuru should be restored to its original state.

After confirming the time, Yinyu's eyes fell on Qianzu inadvertently.

In order to ensure the treatment effect, the patient is of course full of fruit when entering the device.

Qianhe has a very good figure, and I don’t know how such a petite body exerts such a strong combat power.

Ah, Chizuru's naizi is actually bigger than what I had seen before, it is indeed hidden... No, I'm paying attention to something strange!
