Su Jing, the son of Jinling, was originally a talented person on the Qinhuai River, but on the day of his father's sudden death, he was dragged into a desperate situation by a huge debt of 37,000 taels. When creditors swarmed in with IOUs stamped with his father's official seal, he was shocked to realize that his father, who had been honest all his life, had secretly funded the Gewu organization and wasted the family property on "wonderful skills and ingenuity." Falling from the clouds piled with sage books to the mud, Su Jing found "The Method of Purifying and Condensing Fats" in a hidden compartment in his father's study. He gambled with human dignity and brewed the dirty and fragrant "Jade Soap" in the woodshed.
When the street test soap defeated his peers, and the debt-for-equity swap agreement outwitted the powerful enemy, he used the shrewdness of a businessman to turn things around. Even when the "Jade Face" trademark was coveted, he reestablished his character under the name of "Qinglian Soap", which coincided with the way of a gentleman to "come out of the mud and remain untainted". From a down-and-out scholar to a workshop manager, Su Jing not only had to repay huge debts in the ups and downs of the business world, but also gradually understood the weight of his father's "dream of a strong country" - those mechanical drawings and chemical formulas regarded as "routine skills" were the key to defeating the Ming Dynasty. In the thick fragrance of soap, a counterattack related to the survival of the family and the changes of the times is quietly beginning.
