The CEO's Immortal Heiress

The true heiress returns, but instead of fighting the fake heiress, she reveals her ancient Cultivation. She cares little for family drama, focusing on training. She resolves crises with spells, humiliates the fake heiress and relatives, and heals diseases. People fear her power. A CEO falls for her, becoming her loyal ally. She never claims the heiress throne, becoming a true cultivator.
