Lin Yan, a modern financial elite, traveled through time and became the son-in-law of the Tang Dynasty. When Peijia Cloth Village was in a crisis of slow sales, he amazed Chang'an with modern business skills such as improved looms and pre-sale coupons. Facing the difficulties of the second uncle of the Pei family and the suppression of the Persian business group, he skillfully used joint-stock systems, futures and other means to set off a commercial storm in the West Market. He also pioneered "flying money" and "credit coins" to rewrite the financial structure of the Tang Dynasty.
In the ups and downs of the business world, he and Pei Mingshu, the legitimate daughter of the Pei family, went from being a contracted couple to walking hand in hand. With the courage to "break and then build", they dealt with the intrigues of the court and the secret struggles of the feudal town. The prince invited banquets, the prime ministers questioned him, and pirates intercepted and killed him. Every step was full of dangers; from leveling warehouses and stabilizing grain prices, to opening up routes to the South Seas, to allying with merchants to serve as kings, he used the abacus as a sword to carve the legend of "commerce connecting the world" on the scroll of the prosperous age.
When the Persian coup ignited the war in the Western Regions and An Lushan rebelled in advance, Lin Yan led his "Four Sea Business Alliance" to stir up the situation with advanced technologies such as steam engines and railways. Let's see how this son-in-law broke the prejudice and created his own business empire and immortal legend in the prosperous age of the Tang Dynasty.
