Lin Ran, a doctor of botany, once traveled through time and became a bankrupt dyeing shop owner with a debt of thirty-eight thousand taels. Her stepmother wants to sell her to pay off her debt, her fiancé breaks off the engagement and marries another woman, and everyone in Jinzhou is waiting to see her joke. It's a pity that they don't know that she has a database of five thousand years of plant dyes in her head!
From restoring the "Imperial Purple" that had been lost for thousands of years, to having the regent condescend to tie her apron and mix dyes - she crushed her peers along the way, tearing out the residue with her hands, and turned the broken dye house into the number one business in the empire.
At the conferment ceremony, the emperor asked her what reward she wanted. Lin Ran bent down and helped up the civil and military officials who were kneeling on the ground, and said with a smile: "My daughter wants to change the rules of the Royal Weaving Bureau."
