The modern boss Lin Mo wakes up and transforms into a poor scholar from Chang'an in the Tang Dynasty. With a modern knowledge base, he first opened the market with a piece of "soap", and then opened a "novelty warehouse" to sell glass mirrors and ice cream, and his business was booming throughout Chang'an. But this boom aroused the jealousy of the wealthy businessman Wang Yuanbao, who spread rumors and disrupted the situation with low prices. Fortunately, he met the enlightened and talented Liu Qingyuan, and the two teamed up to use a "membership system" and "joint activities" to break the situation. What's even more surprising is that he also relied on the "improved water wheel" to help the people solve irrigation problems, and used the "simple water purification method" to deal with floods. He was finally recognized by the court and planted modern business in the soil of the prosperous Tang Dynasty.
