The Noblewoman Returns in Glory

After Qing Yu's first mission ended in failure, her soul transmigrated through time and space into the body of a little girl in the Great Chu Dynasty, who had been abused for years.

Later, after uncovering the secret of the girl's origins, she returned to her birth parents, hoping to get answers on the girl's behalf.

But her biological mother's attitude and actions only made her doubt things all over again.

As she gradually uncovered the truth, she discovered another secret, and behind it lay a massive conspiracy.

(I picked the wrong setting during the Jianwen era. It's not a matriarchal dynasty!!!)
