My Ex-Girlfriend Sold Scrap and Exposed My Identity as a Tech Prodigy

Lu Chen transmigrates to a parallel world where ferocious beasts exist.

He has no badass skills granted by a System, only an exceptionally powerful brain.

So he quietly starts inventing all kinds of weapons...

After he breaks up with his girlfriend, she sells off his "scrap metal."

But...

"Holy crap, this is the Hummingbird prototype, the first-generation unmanned reconnaissance aircraft!"

"This exoskeleton is as light as a feather, yet it provides so much support!"

"Light sabers really exist in this world, but isn't this thing way too powerful?"

"Is that... an arc reactor? The thing in Iron Man's chest!"

"No way, these are just things he threw away? Are you kidding me?"

The whole internet is shocked.

His ex-girlfriend is stunned too!

Wasn't Lu Chen just a pretty boy who lived off women and never achieved anything?

Then where did all these things come from?
