Lin Yan, a modern financial trader, traveled through time and became a penniless scholar during the Xianping period of the Northern Song Dynasty. With his insight into the loopholes of Jiaozi, he started by forging Jiaozi, founded Huitong Bank in Chengdu, introduced the reserve system and bill of exchange business, and rose rapidly. He met Liu Qingniang, who was proficient in arithmetic, Su Xiaoxiao, an intelligence expert, and Ana'er, a Persian businesswoman. The three confidantes became his right-hand men. In Bianjing, Lin Yan led the issuance of national bonds and salt reform, and launched a thrilling financial secret war with the powerful Prime Minister Wang Qinruo, eventually overthrowing the old party. He led his fleet westward to Nanyang, established Zhiyuan Port, signed the "Four Seas Treaty", built a financial empire spanning the East and the West, and truly realized his ambition of "connecting the world".
