Grandpa's Grand New Year's Eve

On the eve of the New Year, Ye Fan, a village elder left behind, expected his children to not come home for the holiday. To his surprise, he saw his three adorable granddaughters (Guoguo, Doudou, and Diandian). At this moment, he accidentally activated the 'Granddaughter Spending Reward System': As long as he spends money on his granddaughters and makes them happy, he can obtain various treasures and even longevity rewards!! The first task, 'Buying Snacks for Granddaughters', was easily completed, with Ye Fan spending over six thousand yuan, making his granddaughters happy. The system then rewarded a whole box of golden ingots, revealing the system's extraordinary nature. Back at home, facing his daughter-in-law Gaofen's disdain, Ye Fan gave his three granddaughters New Year's red envelopes, each containing a golden ingot, shocking his son Yehu and daughter-in-law! After successfully completing the task, the system rewarded the 'Longevity Pill'— Ye Fan took it and instantly became ten years younger, with his white hair turning black and his physique becoming strong, leaving his family dumbfounded!! The granddaughters proposed wanting a 'big house', and the system issued a new task, 'Give each granddaughter a set of luxury housing'. The successful reward is to become twenty years younger!! Ye Fan, without hesitation, took his granddaughters to the most expensive real estate department in Jiang City. There, they were successively mocked and driven away by a self-interested saleswoman and Ye Fan's old rival, the village chief Liu Manzi and his wife, who despised them as 'poor ghosts'. Facing the humiliation, Ye Fan announced with arrogance that he would buy a 'tower king' (top-tier luxury residence) for each of his three granddaughters, with a total price exceeding thirty million. Amidst the incredulous mocking of the crowd, Ye Fan took out a whole box of heavy golden ingots from the system space. When the box opened, the dazzling golden light shone on everyone's shocked faces, completing the ultimate reversal and face-slapping.
