Hi can u help me find the title? I might’ve removed my bookmark or review and I really can’t remember

It’s a fantasy royal manhwa (possibly transmigration or regression) where she was young and got adopted (not by the ML okay?). I believe she had powers to help the territory against invaders or natural disasters smth like that

And one day during like a battle she met the ML there and then they were raised together by the handsome guy who adopted her (which was possibly a duke or general)

THANK YOU THANK YOU IF U KNOW THIS
