Recommendations Technologically advanced civilization transmigrated to a sword and magic world

Something like Summoning Japan instead of something like Gate. It can be anything, even a mega corporation that has a hand on multiple buisinesses.
As long as

1. It is technologically advanced
2. Is transmigration to a sword and magic world
3. Can self sustain itself
4. Can be on Novelupdates, Scribble Hub, Royal Road, or Webnovel

Would prefer if the military they have is similar to USA or WW2 Japan instead of modern day Japan. Never stopped kn developing their armies and weapons. Offensive army instead of a defensive army. Can be a warmonger as long as it is reasonable.

 

The Empress's Gigolo

Mc has the ability to transfer/teleport between two worlds (One is modern day earth and the other is a cultivation world stuck at the bronze era) with this ability and whilst also being held captive by an empress of a declining country he uses technology and cultivation resources to build his force and status up in both worlds.

 

I know about this. Read a few chapters a few chapters last year. Sadly not what I'm looking for though. I'm looking for an already advanced civilization transmigrated to a sword and magic world. Not an individual upgrading the technology of a backward civilization.

Thanks for the effort though.

 

I Have a Mansion in the Post-apocalyptic World

The mc has the ability to transfer/teleport between parallel worlds (one is modern day earth and the other is a nuclear apocalyptic world hundreds of years advanced of earth and its current technologys) with this ability and the scarcity of resources in the apocalyptic world he trades food and materials for technology eventually creating a technology empire on earth whilst also rebuilding a militaristic force on the apocalyptic world.

 

World Domination System

Although mc doesn't bring much technology to this world it's full of magic and innovative ideas as he tries to improve his kingdom.

I am the god of games

Mc becomes the god of the declining and despised priesthood ',Game' with this priesthood/Godhood he tries to create firm believers by making the world into a moba game.

Cthulhu Gonfalon

Mc posses a body of a Jellyfish and works his way up to Godhood, creating his own church which develops into a country with his ideas and knowledge from earth he tries to create a paradise for his believers

 

The Record of Unusual Creatures

The MC is working for a

Spoiler

civilization that has attained divinity

.

It's an empire that

Spoiler

is spanning multiple universes

.They make use of both technology and magic to the point there is no difference between them.

He isn't that good with magic so he is mostly using the gadgets from the Empire and stuff he picks up on his travels.

It's not completely isekai because he can still return to his own world. Sometimes he travels to a world of sword and magic, sometimes a futuristic world, sometimes a modern world.[/SPOILER][/SPOILER]

 

1.Out of space ( Exactly what you are looking for 100%)
2.War that transcends timelines ( Kind of)( WW2)
3.Magic industry empire ( Kind of)
4.Age of Cosmic Exploration (Exactly what you looking for but technological advancement no magic total scifi)
5. Empress's gigolo ( technically exactly what your looking for but slow)
6. Release that Witch ( Biggest name in this genre)

For me personally gate and summoning japan both were extremely boring as gate had Very bad Mc while japan summoning was really lackluster and too op with some really stupid characters.
I enjoyed above mentioned novels much more than gun porn of gate and summoning japan even though technically they all are in same vein. Might be cause i like underdog story better.

 

*Shameless Promotion*
The story of how a Cultivation Universe was Conquered by an Interstellar Weapons Platform
Here's an extract from the latest Chapter.

 

Wew it's similar to Reincarnating into a Fantasy world as an Autonomous Machine Arsenal but probably way, way less murdery? The AI is made especially for planetary genocide so it can't understand shit. It introduced a human soul but it really does not contribute to the story. Git way out of hand until it killed a god in just a few chapters. Got boring pretty fast to be honest. There's no story. It's okay to be stupidly op, just make sure to write a story.

This is way better to be honest. But i prefer the concept of Titan of Steel to be honest. I prefer the dungeon aspect. Sadly it feels like Titan of Steel was wasted potential. It was okay, but it could be way better.

 

XD it's actually inspired by that one. But I agree with the problems it had. You mentioned, which is why I decided to try my own hand at the idea.

MC is still pretty OP, but he starts off more middle of the road in power in this setting, and while he is sapient with his own personality, he's still an AI at heart and wont suddenly try to become human.

 

Maybe something like:
Kochugunshikan Boukensha ni Naru (MC's a galactic navy's officer, his ship somehow got crashed/attacked while traveling in hyperspace, forcing him to use the escape pod to the planet below & found out that it's a medieval fantasy kind one. Think of Claude from Star Ocean The 2nd Story game)
Combatants Will Be Dispatched (an evil organization doing some interdimensional experiment & isekai the MC in order for their conquest of another world)
