Great-Grandma is the Supreme Cultivator Ep. 6

Leonard Poe, descendant of Veronica Poe, falls for Ivory Sowle—unwittingly making an enemy of her jealous admirer, Frank Lawson, who ruins his career and forces him into delivery work. Witnessing her three powerful adopted heirs abuse their power to oppress her own great-grandson, Veronica decides to reshuffle Great Arkland's elite families, overthrow the corrupt order, and raise the kind-hearted Leonard to power.
