Although Shi Yishan was cruel and greedy, he wasn't stupid. He knew that even though he had suddenly come into a large sum of money, it was best not to use it for a year or two. Everyone knew he spent money lavishly and never had any savings. If he suddenly had a lot of money, even an idiot would know something was wrong.
He needed to come up with the perfect excuse to legitimately explain the money in his possession within the next year or two.
So after hiding the money, Shi Yishan continued his job as a driver, pretending nothing had changed. He even stopped his excessive spending and became more diligent at work, earning praise from his supervisor!
