Invincible Copying: I Took in an Abandoned Female Cultivator and Raised Her into an Empress

[System + copying cultivation arts + invincibility + reverse aging + character development] Lu Fan copies his master's cultivation and techniques, then leaves Daotai Mountain. He saves Jiang Muxue, an abandoned female cultivator, treats her injuries, removes her poison, and implants a Nine-Treasure Dantian. Jiang Muxue reaches the 300th level of Qi Refining and returns to her sect for revenge.

Lu Fan is over a hundred years old and looks ancient, so he cannot meet Jiang Muxue in his true appearance. The Longevity Art extends his life, while a secret reverse-aging technique restores his youth.

Grateful for Lu Fan's kindness in giving her a new lease on life, Jiang Muxue vows to become her master's Dao companion. With her Nine-Treasure Dantian and Exquisite Spirit Root, her cultivation surges, and she attains the Great Emperor's Dao.

A young man with a head of white hair and handsome features appears before Jiang Muxue.
