Zhao Qianmo, an accountant who was laid off, rode an electric bike and became a delivery boy. He ran orders during the day to save capital, reviewed trading at night to look for opportunities, and used his accounting brain to make the first pot of gold from the stock market. Once he spoke out for justice, he got involved in an entanglement with the business giant "Shikun Clan". He suddenly discovered that the streets he walked through to deliver food and the fluctuations on the K-line chart were secretly pointing to the same shadow. So, he silently laid out two chessboards: on the bright side of capital, he followed values and let the snowball roll down the hillside; on the dark side of the city, he calculated people's hearts and looked for answers to a buried old debt. This is a story about how to use the most hard-core financial thinking to make accounts for yourself, break the situation, and make a comeback on the dual battlefield of reality and capital.
