Xiang took his last breath on the cold ground of the family ancestral hall, and the fire devoured the Lu family's century-old foundation. In his previous life, he was obsessed with the craft of making ink, but naively believed that "the aroma of wine is not afraid of the depth of the alley", so he entrusted the family's secret collection of top-grade tung oil tobacco refining skills and channels to his seemingly gentle Huizhou partner Cheng and his cousin Xiong Yurou without reservation. In the end, the result was that the technology was stolen, the channels were taken away, the family was falsely accused of "passing off inferior goods" and offended Tianyan, and the whole family was executed. When he opened his eyes again, Lu Xiang returned to three years ago when the family crisis first emerged. At this time, Huizhou's three major families, Cheng, Fang, and Wang, were relying on their palace connections and capital strength to eye the Hubei tung oil producing area. In order to gain dependence, the local Zhou and Li families had secretly colluded with Huizhou merchants, setting up a trap in the name of marriage, with the intention of annexing the Lu family's ancestral oil mill and forest. With the memory of blood and fire in his previous life, in this life, his goal is clear: to find a way out in this cruel chess game intertwined with power, money, and skills. The road to climb is destined to be lonely, and every break comes with a new price. When he finally stood in front of the "Gongmo Competition", he presented not only the "Purple Jade Light" smoke material that was the best in the world, but also a brand-new tribute ink supply map led by Hubei Lu Family. But Lu Xiang knew that becoming the "top tribute supplier" was just the beginning, and the battle with the ultimate black hand who controlled everything in the palace had just begun.
