I recommend a new book: Douluo: Peerless Dragon Emperor. It's a new book by Hong Chen, and both books will be updated simultaneously. It won't have a bad ending; I guarantee it will be completed.
As always, it features a single female lead, no flirting, no harem, and she is devoted to only one person.
Synopsis: Reborn inside an egg, spending countless years in endless darkness.
A dragon's Dragon Roar shook the heavens, and all the beasts howled, proclaiming the passing of one era and the beginning of another, the opening of an unknown age.
Standing in the Spirit Hall, looking at the huge angel statue, I vaguely remembered that countless years ago, someone became a god.
Unless the Dragon Race is revived and the Dragon God is restored, Soul Beast cannot become gods.
Your His Royal Highness the Crown Prince, there are other ways to restore the Dragon God besides yourself...
This book features a single female protagonist, no harem, and no ambiguous relationships.
