I Have a Goofy Cashback System

Wang Xiaotian is a low-level employee at a company. On his Saturday off, his eldest and second eldest sisters both go away on business, leaving their two pairs of twins, ten nieces and nephews in all, in his care. The five boys and five girls leave Wang Xiaotian utterly frazzled. The moment the ten little masters arrive, the Cashback System, which multiplies his spending by a hundred, binds itself to him. From then on, Wang Xiaotian's happy days begin. See how he and the little masters make the most of life.
