[Stellaris + Warhammer + Human Alliance] [Level 10 Scientist] [Equivalent to extremely high research capabilities, plus handcrafting skills far exceeding Level 8 Fitter, capable of handcrafting anything]

When human civilization broke free from propulsion and reached the stars, mastering faster-than-light travel marked the beginning of the interstellar age.

However, the situation is often different in different universes. In StarCraft, you need to travel faster than the speed of light to join the ranks of the interstellar empires, but Warhammer is different.

The Federation of Humans has not mastered faster-than-light travel; it can only do so through subspace.

What does it mean that a Level 10 scientist from the Starkind Alliance has arrived in Warhammer?

If I were just a scientist, with only the insignificant power of a mere 300 million tons in one hand.

but!

Do you see my ability to build a network in just a few days, or at most two months?

Do you see those tens of millions of Space Marines and the overwhelming fleet behind me?

Chaos? Tell me, how many fleets does he have?

It's just a large power bank.

Humanity will surely fulfill its divinely ordained destiny and conquer the galaxy.

All aliens must either submit to humanity or be eradicated. They may not understand, but they must obey!

In the 40th millennium, humanity teeters on the brink of destruction, and the universe pervades with eternal war. Within the Warp, the Dark Gods whisper, engaging in their never-ending grand game, manipulating the course of fate. The unexpected arrival of a stranger unleashes a wave of change that deviates from the predetermined destiny. Doom Slayer!

Crossing over is a good word, but not everyone is willing to do it

, especially to go to some very dangerous worlds...

But sometimes, you have no choice~

Crossing over to the Warhammer 40K world is very tragic, and even more tragic is that Luo was almost crushed by the guards in front of the Golden Throne. Is there anything more tragic?

"You ***..." Looking at the chaos symbol in front of him, the protagonist said

In a church of the Silan Theocracy that is about to be destroyed by the Great Tomb of Nazarick, an unclosable portal is found, connecting to the world of Warhammer 30K.

Thus, Warhammer meets the Great Tomb.

Ainz Ooal Gown: Damn, I'm a native!

PS: The original work is an expansion of my answer in "What would happen if the alternate world in Overlord was discovered by the human empire during the Great Crusade in Warhammer 40K?" The original

answer has been completed, and many plots of the fanfiction have been modified, which are inconsistent with the original answer. I hope everyone will support it.

The protagonist Ge Shisan wakes up and finds himself traveling to the Origin Galaxy and becoming a Tiannuo Pirate. He also discovers that he has obtained a system that can travel through the heavens and myriad worlds.
