By completing sign-in tasks at designated locations, he quickly accumulated wealth, from exchanging mobile phones and shoes to buying cars and houses, and even starting a company and becoming the boss. He cleverly hid his wealth to avoid entanglement with his ex-girlfriend, and at the same time used the system's rewards to invest in his business, eventually becoming a multimillionaire. At the class reunion, he appeared as a successful man, focusing on his career and family.
