Yokosuka Naval Base, Hangar No. 51.

"Is this the place?"

Hidden in the shadows, Fang Zheng looked at the warehouse below, which had only a few lights. From the outside, it didn't look like a place where any secret weapons were hidden. But this was understandable. If there really were any secret weapons, building a warehouse that looked unusually cool would only tell the enemy that there were secrets here.

It was already late at night, and there were not many soldiers patrolling nearby. As a "confidential location", the defense here was quite lax. But Fang Zheng didn't care about this. After Nymph hacked into the base's alarm system, he led the little angel through the defense line quietly and came to the No. 51 hangar.

"Right now."

"Yes, Master."

After making sure that the nearby patrol had left, Fang Zheng gestured to Nymph, who nodded, then walked to the hangar, stretched out her hand and waved it gently.

"drop--"

The next moment, the door of the hangar slowly opened.

Walking into the hangar, with the help of the light in front of him, Fang Zheng could see a blue, oddly shaped ship parked in the dock. It was isolated by heavy restraints. Under the light, Fang Zheng could clearly see the name on it.

I-401.

"Hmm... I think I've seen this animation somewhere..."

Seeing the submarine in front of him, Fang Zheng finally had some understanding of this world. If he remembered correctly, the setting of that animation seemed to be similar to KanColle. He watched it a few times at the recommendation of his colleagues, but as for the plot... who the hell still remembers the plot.

"Nymph, check the condition of this submarine."

Although Fang Zheng was a little disappointed that it wasn't Minerva or the white Trojan Horse, he changed his mind and thought that submarines were actually quite cool. At least in the main world, there were no such ships that could dive underwater. Although it couldn't reach 100% of what he imagined, 70% should be no problem.

But before that... let's get this thing first!

Hearing Fang Zheng's order, Nymph also reached out and placed her hand on the submarine. Soon, rows of light screens appeared in front of her, and then Nymph widened her eyes in surprise.

"This is……"

"What's wrong? Nymph?"

“No… Master…”

Hearing Fang Zheng's question, Nymph shook her head. She thought for a moment, as if considering how to organize her words.

"I just analyzed the core of this Sea Mist Battleship and found that its core architecture is much more advanced than current human technology..."

"Could it be an alien creature?"

Hearing this, Fang Zheng also became curious, but Nymph shook her head.

"No, Master. Based on the code backtracking, we can determine that this is a pure Earth civilization. Its basic core principles are no different from human civilization and technology, except that they are more advanced."

"This is really interesting..."

After hearing Nymph's description, Fang Zheng understood what she wanted to say. If these sea fog warships were from an alien civilization, then their core codes would definitely be different from those on Earth. The reason is simple. Aliens must have their own planets, and unless their planets are located in the same galaxy as Earth, the rotation, revolution, atmospheric density, gravity conditions, etc. of that planet would definitely be different from those on Earth. The civilization and technology developed under such conditions would naturally be different from those on Earth.

According to Nymph's analysis, the Sea Fog Battleship did not come from outer space, and its core code and reference values ​​were still the standard values ​​of the Earth. Therefore, Nymph was sure that the Sea Fog Battleship came from the interior of the Earth rather than from outer space.

"...Not only that, I also discovered a problem, Master...The mental model of this battleship relies on the power provided by another core hidden inside. The battleship itself is not enough to provide complete core computing instruction data. Moreover, the core instructions are engraved with the underlying code and the highest priority command - to find a person named Chihaya Gunzo and become his battleship."

“Is there a way to fix this?”

"Of course, as long as it is a change at the information level, nothing can be my opponent, Master."

In response to Fang Zheng's question, Nymph nodded, then she stretched out her hand and waved it in the air.

"Rebuild the core code again and perform multi-core linkage..."

“——”

As Nymph spoke, the blue submarine in front of them began to glow.

"Core linkage processing completed, starting to modify the underlying code and delete extra instructions..."

The light on the battleship became more and more dazzling. At the same time, countless pentagonal grids began to emerge around the submarine and connected into one.

"...Enter the engraving system command code, and the database will be changed."

Having said that, Nymph put down her hand. At the same time, the submarine that was originally shining with a pale blue light returned to its previous appearance.

"The modification is complete, Master. You can activate it by placing your hand on it."

This is fingerprint activation.

After hearing Nymph's report, Fang Zheng looked at the submarine in front of him curiously, then he walked forward and placed his hand on the battleship.

“——!!”

Soon, along with Fang Zheng's movements, the submarine in front of him once again emitted a dazzling blue glow, and then the entire submarine began to tremble. If Nymph had not already cut off the detection and alarm systems here, I'm afraid that all kinds of alarms would have been sounding non-stop by now.

Then, a beam of light shot out from the surface of the submarine and shone in front of Fang Zheng. Then, a figure slowly emerged from it.

She was a beautiful girl with long pale blue hair and green eyes. She wore a dark blue sailor suit. Her delicate face, like a doll, had no expression at all. She just stared at Fang Zheng in front of her quietly. Then, the girl slowly spoke.

"I-401 activated, identification confirmed... Master."

"Hello, my name is Fang Zheng."

Looking at the girl in front of him, Fang Zheng smiled and spoke.

"What's your name?"

"My identification name is Iona, Master, and I am the mental model of the submarine I-401 of the Sea Mist Fleet."

The girl glanced at Fang Zheng and then gave her answer.

"We are weapons. We fight by following orders. That's how we are... So we long to be ordered. Therefore, please give us orders, Master."

"Well……"

Hearing this, Fang Zheng was stunned for a moment, then he glanced at Nymph.

Why does this sound so familiar?

Facing Fang Zheng's inquiring gaze, Nymph gave a very smug smile - it seemed that the little angel was the mastermind behind all this.

Fortunately, at least Nymph did not transform Iona into her original appearance. If Iona also came out with an attitude of "I can do anything, please don't abandon me, master", Fang Zheng would be really desperate.

"bite--"

At the same time, the system prompt sound appeared in front of Fang Zheng along with the subtitles.

[Activity Mission: Completed by fighting poison with poison]

It’s really a swish.

Looking at the activity prompt in front of him, Fang Zheng sighed, then he raised his head and looked at Nymph and Iona.

"Nymph, remove the shackles, Iona, prepare to set sail!"
