Electromagnetic science from pirates
This was the story of a transmigrator named Mo Fei who had become a spy of the Don Quijote Family from the Pirate World. He used electricity to treat himself, treat the entire family, and teach them the Five Lectures, Four Beauties, Harmony, and Freedom. Then, he treated the wireless multiverse of multiple parallel worlds.
A few years later, Mo Fei began to take on high-end businesses.

Waxing the white hole, polishing the black hole, and stabilizing the wormhole.
He would collect second-hand white, black, red, yellow, and blue dwarf stars. He would sell them in large quantities at a good price, and he could even exchange them for stainless steel washbasins.
The gamma-ray burst would regularly clean up all kinds of evil gods, save the world's sanity value, and solve all kinds of hidden dangers that could destroy the world. It would not cost money if it was not cleaned up!

I really like how you combine the KHR and Danmachi stories; it's great to read. PS: You could do a KHR and Yozakura Family story.
