Looking for a Book with Good Writing and Reasonable Plot, Ancient Times, Fantasy, and Apocalypse Are All Acceptable

There is a shortage of books. I used to read novels about cultivating immortals. An ordinary genius would rise to the top after two thousand or three thousand years, a peerless genius would ascend after eight or nine hundred years, and the protagonist would ascend after two or three hundred years. Now I am reading a novel about ordinary geniuses at two thousand or three thousand years, a peerless genius after eight or nine hundred years, and the protagonist after twenty or thirty years. Hahahahaha, I have left the world.
