Chen Xuan, a young man of Chinese descent, inherited the mantle of a thousand-year-old credit swordsman, and landed in North America with the mysterious prophecy and the law of cause and effect. He thought this was just another loan parade, but he didn't know that he had already stepped into a huge whirlpool. From prophesying on the street to stirring up Wall Street, from left-right state election to holding power, he used his sword as his pen and prophecy as his strategy, eventually turning the entire North American continent into his biggest "credit game."
