(Interstellar) Shoulder to Shoulder with the Sun

[Unfinished. The author is unwell. Until we meet again, if fate allows. Enter at your own risk.]

Fulunjiesier, the beloved little prince of the Interstellar Federation, always thought he was the protagonist of this world, until one day a little girl fell out of the sky and nearly crushed him to death.

The little girl was fine, but his miserable life began right then.

Dong Weiyang: "Hah! Little girl? I'll show you what it means to be equal to the heavens!"

P.S. 1. An interstellar cultivation novel. The female lead knows alchemy and focuses on the alchemical path. She's ridiculously powerful.

2. The female lead isn't a typical little girl. She just started Foundation Establishment early, and her appearance changes very, very slowly after that. In this story, people in the interstellar era can live for more than three hundred years. She looks about seventeen or eighteen, which is why people think of her that way.

3. The writing style may be unusual. Read at your own discretion.

4. Yes, the title means exactly what you think it means.
