Cosmic Civilization: I'm Really Just a Scientist

A Technological Universe, From One to Ten Dimensions and From Level-One to God-Tier Civilizations

From Earth to the Solar System → the Local Group → the Third Galactic Arm → the Milky Way → the Local Supercluster → the supercluster → the universe → beyond the universe. I want to read a book with this kind of scale. I wonder if one exists? Preferably a traditional-style novel.

Novels About Traveling from Earth into the Universe

Something similar to Swallowed Star, The Arrival of the Strongest in the City, Rise of the Revival Era, and Cultivation Frenzy. Ideally, it starts in a middle or high school, with the protagonist rising step by step, entering the universe, joining humanity, and fighting alien races. That kind of story.

Interstellar, Technology, Mecha, and Starships

Something normal.

I Will Protect My Country Alone. I Have No Regrets About Being Chinese in This Life, and I Will Be Chinese Again in the Next

The protagonist does so much for the people, but they don't know it and curse him. In the end, they regret it.

Any Books That Explain Aliens?

I recently came across a novel called Proving the Multiverse from the Start. This kind of story is so good. Please recommend more if you know any.
