From Warhammer to Hyperdimensional Harem

As Deputy Captain of Mithril's Western Pacific Battle Group TDD-1—Richard Mardukas.

As Commander of Mithril's Western Pacific Battle Group Marine Corps Special Response Team (SRT)—Andrew Sergeyevich Kalinin.

These two men had experienced so many storms and upheavals, what hadn't they seen?

They had witnessed the most intense scenes of the Cold War between the two superpowers, moments that could be described as just one step away from world destruction.

However, the secret that this fifteen or sixteen-year-old girl told them today completely moved their usually unmovable expressions, showing obvious signs of astonishment.

Honestly, they didn't believe it at first—how could something be so outrageous? But the girl before them had first demonstrated what looked like supernatural abilities.

She had made things disappear into thin air, placing them in some space, then taking them out again.

"Captain, you've really told us quite an incredible secret. From now on, this will make it so we can't drink alcohol anymore."

Richard adjusted his glasses and said this somewhat jokingly.

At the same time, he was looking at the video on the computer, which was also the captain's incredible operation—downloading special videos.

"I very much agree with Deputy Captain Richard's words."

Andrew nodded like this, his expression also very serious.

This seemed like a joke, but they really had to quit drinking.

Of course, these two had always been very clear about separating public and private matters. When they were working, they absolutely wouldn't touch alcohol, only drinking a little when in a confirmed safe environment.

Even if they really drank heavily and got drunk, they wouldn't make the foolish mistake of letting secrets slip while drinking.

But this time, the secret Tessa had revealed was truly too shocking, much more outrageous than even the Whispered identity.

So from now on, to better guard this secret, they had to eliminate even the slightest possibility of leaking it. Even if there was only a one-in-a-million chance, it had to be eliminated.

In a flash, about twenty minutes had passed since the captain revealed the secret about the parallel world content.

"Captain, have you considered this possibility?"

Richard said to the girl before him with a very serious expression, making her nervous too.

"Wh-what possibility?"

Tessa's tone was also very tense, and she seemed somewhat restless.

Did the deputy captain seem about to say something that would involve her life and safety?

Of course, she didn't think the deputy captain would betray her or send her to some experimental table.

The deputy captain seemed worried that the "Hyperdimensional Channel" itself was dangerous.

Worried that if someday the people she invited over had ulterior motives?

Right, there could also be trades—what if the things teleported over had problems?

"They all seem to be parallel worlds, right?"

"Yes."

"Theoretically, technology should also be interchangeable, right?"

"Yes."

As expected, the deputy captain was worried about possibly bringing over dangerous technology that could leak to dangerous people like Amalgam, thereby harming this world.

And technology wasn't necessarily just weapons—it could be viruses, since biochemical viruses themselves could be used as a type of weapon.

So if theoretically it could be used, it meant the biochemical viruses from there could also be created here.

"This means that the two parallel worlds, aside from some developmental differences, have the same environment, right?"

"Yes."

Tessa nodded again.

Then deputy captain, just be direct, don't keep us in suspense—she actually roughly knew what he was going to say.

Of course, Tessa didn't point it out directly. This might be the deputy captain wanting to show off his wisdom.

"Then isn't there a possibility..."

That the other side's technology or products could be used here, causing problems, right?

"The other world has Tyranid alien lifeforms. In some corner of our world's universe, similar species might also have been bred."

Ah?

Tessa hadn't expected the deputy captain to say this—it was different from what she had anticipated.

"What? Captain, you hadn't thought of this possibility?"

Richard adjusted his glasses again, his serious tone also carrying a somewhat teasing quality.

He could see that Tessa was trying to guess what his speculation was.

"This, this, not very..."

Possible—these two words, Tessa ultimately didn't say.

The possibility the deputy captain mentioned wasn't impossible, but it was also the most terrifying possibility!

From the performance of the Tyranids in the videos they had seen, if they really broke out in her world, the result would be humanity's doom.

Moreover, from some dialogue and fragments they had learned, this wasn't even the Tyranids' real invasion.

This was just Tyranid advance forces infiltrating this world, developing, and causing chaos.

Right, this level was actually called chaos, not even the bugs' real invasion.

This chaos was just to create opportunities for the Tyranid hive fleets to invade.

When the real forces came, it wouldn't be ground warfare on planets anymore, but true interstellar war sweeping across star systems.

"However, you don't need to be so nervous. It's just this possibility. But the war with Tyranids in this world happens at a very distant future time, indicating that our side should be safe during this current period."

Andrew spoke up.

"But it's not impossible that they really wouldn't arrive early in our world? Just like how human development in the two parallel worlds has some differences, maybe Tyranids exist on our side too. Due to some changes, they might have already wandered to the Milky Way? Wandered near the solar system?"

The deputy captain raised this terrifying possibility again, making Tessa's face tighten even more.

"Alright, Richard, you're worrying about nothing."

"This is a bit of needless worry, but we can't completely ignore it. Speaking of which, there's a theory that the Whispered's black technology comes from parallel worlds. Now, from the captain possessing this bizarre 'Hyperdimensional Channel,' the possibility seems even higher. Captain, please look."

"Ah?"

"This video codenamed 'Martian World'—you probably haven't looked carefully at its content, have you?"

"What about it?"

Tessa hadn't only downloaded Mr. Gold's videos, but also Miss Martian's.

Then she saw the deputy captain adjust the video, playing a section that briefly introduced that world's giant humanoid machines, called Kataphrakt.

This was similar to the giant humanoid machines AS developed in her world—they looked like similar humanoid mechs, probably just with technological differences, but all designed for convenient warfare use. So this time Tessa listened carefully to the other side's introduction, and her expression became astonished. She understood what the deputy captain was going to say.

"This world's Aldnoah Drive technology and the Lambda Driver system technology we're currently developing are somewhat similar."

Tessa said this incredulously.

Both systems were based on the user's mental energy for activation, seemingly able to respond to some of the user's thoughts—for example, if the user was someone without much sense of security and really wanted comprehensive protection.

Then after using this system, it would trigger abilities suitable for them, deploying special energy fields to protect themselves.

That is to say, it was possible that her world's Lambda Driver system technology might have come from the Aldnoah Drive technology flowing over from Miss Martian's world.

Or rather, the technologies of both worlds belonged to the same source.

"Captain, the half hour is almost up."

Andrew suddenly reminded her, because the captain had mentioned the current situation of that Mr. Gold's world.

"Ah? Okay."

Tessa immediately went online, skillfully entering that livestream room.

She arrived just in time—the other party had just reached the original planet.

With his help in removing the bugs' nest, the war pressure on this planet's people would—

Ah?!!!

Tessa's originally somewhat relaxed mindset was instantly tightened to the extreme.

Was this going to destroy this planet?

Were they going to blow up this planet?
