I remember certain parts about it however, it’s been at least 1 and a half year since I read it.

I remember that the FL was reincarnated, she lived with her grandfather and brother.

Her father and mother still lived on in a different realm or higher ranked country. The mother was a saint, her father was an high ranked alchemist (pill refiner).

They had stopped looking for their children and had adopted another girl to replace the FL there, that girl tried to kill her father by causing his cauldron to explode in a pill refinement contest.

I remember that the brother ended up meeting them later on, they wanted him to continue to live with them however, he wanted to still be with his sister.

I’m not entirely sure if I remember everything right, however most should be pretty accurate.
