Dream of the Red Chamber: Rising to Power as a Minister Through Intelligence

With a photographic memory, a pocket dimension, and one daily piece of intelligence, he leads his family out of hardship. He heads south to study under Lin Ruhai, changing the fates of Lin Ruhai and his daughter, as well as the other beauties of the Twelve Beauties of Jinling.

When Jing Yue looks back, he finds himself surrounded by beautiful women, yet still standing at the pinnacle of power.

(Jing Yue is a compound surname, not a certain little something surname.

The protagonist is not a member of the Jia family and is not related to them, so he can take in as many beauties as he likes without a care.)
