Immortal World : MILF Dual Cultivation

[ Warning: Mature content] Transmigrated into a brutal cultivation world as a weak, lowly Outer Sect disciple, 27-year-old Earthling Lin Tian faces a life of humiliation and certain death—until he awakens [The Sovereign Matriarch Conquest System]. Instead of years of tedious meditation, Lin Tian discovers a much more seductive path to power: Dual Cultivation. Using his system's diagnostic abilities to uncover the fatal hidden illnesses and secret flaws of the realm's most powerful, arrogant, and untouchable mature women, he offers them the only cure—his scorching Yang energy. In return, he ruthlessly shatters their towering pride. From strict Sect Managers and untouchable Peak Masters to Mortal Empresses and Cosmic Matriarchs, no goddess can resist his cure. By healing their bodies and dominating their minds, he transforms these supreme women into his utterly devoted loyal women. Armed with modern Earth logic and an overpowered system, watch as Lin Tian conquers the strongest women in the universe and rises to become the absolute Yin-Yang Emperor! First milf dual cultivation starts in chapter 20. — Description from novelcodex.org
