The Outcast Officially Renamed: Under One Nation

It's probably a sweet little romance, with Wang Ye as the pairing. Other characters will have one-sided crushes along the way! Slow burn, with some out-of-character moments. I've only watched the original anime and have forgotten many details, so I'll be taking creative liberties.

Here's the blurb:

The country assigned me to investigate the Outsider organization behind the parallel-world Guo Jia. I went straight ahead and submitted a proposal: “A Plan for Bringing Another World Under National Control, Starting from Scratch.”

After graduating and landing a secure job, Lin Miaomiao set off on a solo graduation trip. She never expected her very first destination to go wrong, sending her stumbling into a new world.

Later, she caught the culprit who had cost her her iron rice bowl: an unlucky supercomputer born without a world of its own. It calls itself the strongest national weapon in history, and in a way, Lin Miaomiao has to admit it's right.

From mecha-mounted laser cannons to planet-destroying nuclear blasts, this thing has it all!

Later, she successfully made contact with Guo Jia. With her secure job intact and an entire world's arsenal backing her up, Lin Miaomiao tells her superiors to go ahead and make any request. She can handle anything!

“Outsiders? Can they fire laser cannons?”

Wang Ye: Ancestor, no, they can't. So could you put away that thing you're holding?

Zhang Chulan: Sis, you're one of only two people I call sis. Let's talk this out, okay? I'll do what you say.

Feng Baobao: Sis, that thing of yours is so cool.
