Shen Yan was transformed into a poor boy in the Ming Dynasty. His family was destitute and his mother was seriously ill and could not even pay for the next month's care. The bullies in the town came to collect debts, the county school teacher's edicts overtly and covertly hindered him, and the road to the scientific examination was blocked. But he lowered his head and did a few calculations, and he calculated the bully's land deed as his own. He raised his head again and turned over the county's tax debt. Everyone in the city regarded him as a pushover. Only Shen Yan himself knew that his skills as a trader in the financial industry in his previous life were more than enough to stir up trouble in this remote country. But he didn't expect that the game of chess would get bigger and bigger, and the people sitting across from the chessboard would be much more ruthless than those capital predators in the previous life.
