Realistic fantasy themes
It is called this because Utopia sounds very nice. The style is the Renaissance style of ancient Mary Sue fantasy. It builds a harmonious heaven with friendly scale and no expectations.
The way the plot unfolds is: Jiuchongtian War God was "forced" to accept a female protagonist as his apprentice. The reason is that his apprentice Tao Ran committed an unforgivable sin. On the surface, he had to make amends for his apprentice and accept the female protagonist. The entire Tiangong knew about this and agreed that Tao Ran could not control himself but he was a good young man, and the female protagonist was a scheming woman...
Concept: Everyone can be the protagonist in their own world
