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

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

Everything was as expected by the Federal Army, the thing fell off its chain on its first voyage. And this chain fell a little big, and the whole ship was actually lost.

Because it was so advanced, the Federation Army searched several times but couldn't find it, and finally had to give up.

Anyway, there are no nuclear bombs on the submarine, so if you lose it, you will lose it.

It is said that after that, no one in the federal army paid attention to unmanned submarines, at least Otowa has not seen the news of the construction of unmanned submarines on the Internet 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 constantly introduced the submarine to Otowa.

"Wait, 10 years?"

Otowa reacted quickly, and the unusual information was discovered at the first time.

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

When she said this, Pride was written all over Chizuru's face.

Otowa's expression suddenly became strange, if the top brass of the Federal Army found out that the nuclear submarine was stolen by a seven-year-old girl one day, I wonder what they would think at that time?

Led by Chizuru, the two soon arrived at the ship's command room.

The command room was empty, with only a holographic projector. However, when Chizuru activated it, a large number of images instantly filled the entire room.

This is what a 22nd century battleship should be! In Otowa's opinion, this place is not much different from the command tower of a starship in science fiction.

On one of the screens, the news is playing.

Chizuru waved her hand lightly, and the screen was enlarged quite a bit.

"At around 11am today, someone illegally used a flight in the City of London, and the suspect has now been arrested and returned to ......"

Before the host finished speaking, Chizuru waved his hand again, and threw the projected screen somewhere.

"The more technology develops, the more people feel that society is more open and free, but the truth is ...... But it's the opposite. ”

Chizuru'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 covered these things at all. ”

When an object is moving close to the speed of sound, it encounters a strong resistance that causes the object to oscillate strongly, eventually causing the velocity to decay, a phenomenon commonly known as the sound barrier.

When the sound barrier is broken, due to the compression of the air by the object itself, it cannot propagate rapidly, and gradually accumulates on the windward side of the object to form a shock wave surface, and the acoustic energy is highly concentrated on the shock wave surface.

When this energy reaches people's ears, they cause a short, extremely strong explosion called a sonic boom.

The energy of the sonic boom was very large, and the sonic boom produced by the fighter jet flying at low altitude was enough to shatter doors and windows, and the two of them had died in a sense before.

"That's, Chizuru. Otoha hesitated for a moment before continuing, "I'm just leaving, will the people around me be in danger?"

"No, it won't. Chizuru's answer was quite affirmative. "That guy still has to be faced, he can't do this kind of thing. ”

"That's right. ”

Otowa nodded, agreeing with Chizuru's statement.

She had also dealt with Su Baiyu a few times, and this guy really didn't look like someone who would do such a thing.

"But don't be careless because of this, even if she doesn't use this kind of indiscriminate means, there are still many ways to deal with us. ”

"Hmmm......"

If you don't use the tricks of the next three indiscriminate, it doesn't mean that the guy is a good person.

"Then again, we're just going to stay on the submarine after that. Otowa tilted his head.

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

If he really had to stay here forever, Otowa felt that he might not be able to stand it that day.

As if to hear the worry in Otowa's words, Chizuru explained with a smile on her face.

"Of course we can't hide like this, it's just a temporary avoidance. ”

"And after that?" Otoha continued.

"After that, of course, we will kill Su Baiyu's body, and only by getting rid of her can we be freed from this reincarnation. ”

Chizuru's voice was full of murderous intent, and she didn't know what happened to her back then, which made Chizuru hate Su Baiyu so much.

"Is it really possible for her to be killed......

Although he didn't really want to fight Chizuru, Su Baiyu left a deep impression on Otoha.

"Even if that guy is a god, I'll kill you anyway......"

After saying this, Chizuru coughed again.

"Are you alright?"

Otowa grabbed Chizuru's hand, and his face was full of concern.

"I have to treat my injuries first, my body is still too fragile in this life. Chizuru took a few breaths, and then said a little reluctantly: "The 'Deep Sea Fortress' will be handed over to you during this time, and I have to rest for a while." ”

"The body is the most important thing. Otowa nodded.

……

Chizuru's injuries were far beyond Otoha's imagination, and although he couldn't read the data on the instrument, Otoha was able to tell the severity of the matter from the various warning symbols.

It's really a shame that Su Baiyu can do it......

In the 21st century, this is almost a mortal injury, but fortunately, the medical facilities on board are all 22nd century high-tech.

Following Chizuru's instructions and the notes on the instructions, Otowa threw her into a glass pillar and poured a potion into it that was said to last her life.

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

If Otowa is not mistaken, this should be the countdown to Chizuru's recovery. As long as Otowa waits for a week as mentioned above, Chizuru should be back to normal.

After confirming the time, Otowa's gaze inadvertently fell on Chizuru.

In order to guarantee the therapeutic effect, the patient enters the device with a full fruit, of course.

Chizuru's figure is very good, and I don't know how such a petite body can exert such a fierce combat power.

Ah, Chizuru's naizi is actually bigger than what was seen before, and it is really hidden...... No, I'm paying attention to something weird!

Otowa immediately shook his head, and then hurriedly fled the treatment room.
