Oh, this looks like a really interesting story~! However...
I feel like your synopsis reads quite flat. You technically have everything there to indicate a great story, but the delivery feels more like a disinterested attempt to describe a story concept rather than an author pitching their story to readers.
A blurb has to be exciting and/or build atmosphere to convince the reader that the novel will be fun to read.
I would suggest starting with the Huanlong Prince and the disappearance of the the amulet, as that provides a little bit of mystery and excitement to bring readers into the rest of your synopsis and also sets the stage for the characters you're talking about.
You could give it some more gravity, too. It's the big mystery of your story, but you sort of mention of it as an aside at the end, so it doesn't feel important here.
As for your character introductions in this part, I find them to be a little rushed and confusing. If Shen ZhaoChun is our main character, then he should be introduced on his own first and given a little bit of space so that the reader can get a feel for what sort of character he is.
Then it would make sense to introduce Guai Zuoren as your final mystery hook. Also, rather than saying he's "deity-like", it might be better to build a hint of that with some other description - maybe by hinting at his capabilities, or whatever else this is intended to mean?
And, in terms of the prologue... It feels a little unnecessary to me. Having a short and quick introduction to the disappearance as a mystery/legend would be nice, but gaining so much information about the missing man in one go ruins the sense of suspense.
I can't help but feel that what you're explaining in the prologue would be better off being revealed slowly over time in the main story, so the readers can also feel like they're starting to learn who the prince is as they go along.
