During the Zhenghe era of the Great Song, Bianjing’s commercial routes were thriving. Cao Yiyu transmigrated into the body of Ximen Qing, a wealthy Yanggu merchant, carrying modern ambitions for business.
He had hoped to run a peaceful business, but became entangled in the bitter feud between Wu Dalang, Pan Jinlian, and Wu Song, forced to tread carefully at every turn.
Then he unexpectedly gained a golden finger that let him simulate a hundred different business strategies and predict people’s reactions, revealing the keys to success and failure.
Using its simulations, he built chain stores and developed brand marketing, turning a humble baked-flatbread stall into the nation’s leading business.
While others relied on family connections and inherited privilege, he used data and strategy. Ordinary townsfolk flocked to him, and even powerful aristocratic families struggled to compete.
Starting in Yanggu County, he swept across the Great Song’s commercial world, eventually founding an immortal overseas merchant guild whose legend endured for a thousand years.
