Xianxia: Cultivation Starts at 70

At seventy, Grandpa Shen An binds to a power-up system, instantly gaining spiritual roots and unlocking max-level skills like pill crafting, formation arrays, and illusion magic. He eventually becomes the supreme master who dominates the realms of immortals, demons, and monsters. When all the strongest beings from the three realms come to beg him to become their ruler, he ignores them all. Instead, he leads his entire family to ascend to the immortal realm with the philosophy that one person achieves enlightenment and all the chickens and dogs rise to heaven, departing with carefree freedom.
