The Water Spirit of Erxian Bridge

Cultivation, Top-Tier Water Spirit Root, Blind Protagonist, Starts With Spirit Root Testing, Ensemble Cast

I read a novel before, but I can barely remember it. I think the female lead was a wisp of a ghost who became human, maybe. The story started with testing spiritual roots, and I think she had a top-grade water spiritual root. The original female lead was reborn, and they had a really good relationship. But I can't find it anymore. Does anyone know what it is? Please help!
