I'm looking for the name of a novel that might be a fantasy transmigration novel =_=

Those who entered, don't leave! Hold on! >0<
Suddenly, he remembered a web novel he had read before. It was a bit of a fantasy. It seemed that the female protagonist was reborn (or transmigrated) and then cultivated bit by bit. The male protagonist was the ruler of a continent other than the country where the female protagonist lived. He was quite powerful.(In my memory, there are only a few keywords like Ethereal, Water, Supreme Kindness, Continent, etc... I can't rule out the possibility that I might remember wrongly). During the cultivation process, the female protagonist slowly stood in the position and level of the male protagonist. She also collected various pet attributes, such as fire and earth (I remember that the female protagonist spent a long time underground to subdue earth). There wasn't much love, but the author's writing was very good ~
Also, I seem to remember that the second male lead is called Ouyang something, and he's a prince.
In the end, the continent where the male protagonist was located was about to be destroyed, and then the male and female protagonists cultivated some martial arts together to save the world from fire and water…
I still remember that when they met, the female lead saved the male lead's life and did not let go of the male lead's hand in a life-threatening moment, so the latter was a little curious about her…
Does anyone remember what this book is called? If I remember correctly, this title might be a little vulgar?
P.S. If someone wants more details, I can provide them based on my remaining memories. I can't find any keywords on the Internet.
Thank you ~~~~~

One of them might be a fantasy transmigration novel, and the name might be Battle Through the Heavens. This was a very popular online fantasy novel. It described a young man named Xiao Yan who accidentally transmigrated to another world and began his training path in this world. In this world, he met all kinds of powerful opponents and grew up to become a powerful martial artist.
