Lovesickness: Once Upon a Time It Was Difficult to Change the Sea

There Is a Shortage of Books. Anyone Who Has Studied Immortality Has Read the Essay on Seeking Female Power Like Lu Song.

I want to read a book similar to "After Changing Marriage, Cannon Fodder's First Wife and Young General's HE". The female protagonist traveled through time and started exchanging marriages with the original male protagonist in the book. They kept killing each other. They were really killing each other. So far, the female protagonist has always had the upper hand.
