From 9 lines of tags, you can tell that the author lacked a clear direction for the novel. The story starts as a self-indulgent story, where the main character fulfills the author's daydreams by acquiring extreme handsomeness, immense wealth, and other desires effortlessly. Then, it turned into a low-grade sci-fi story filled with incomprehensible and tedious experimental logs where the main character engages in a series of random “fantasy experimental”. Subsequently, the focus shifts to side characters with pointless and unproductive storylines that contribute little to the main plot, while the main character remains absent for an extended period. At this juncture, I decided to abandon the novel.

The most important tag for this novel is 'Unreliable Narrator'. The self-indulgent element stands out as its sole redeeming quality, boasting impressive design, and a remarkably powerful main character.
