Lin Mo was once recognized as a top marketing planner in the industry, and all of his products became phenomenal hits. Three years ago, he suddenly retired and opened a humble teahouse in the south of the city. People in the industry said he had exhausted his talents, and his colleagues laughed at him because he had become outdated and was eliminated. Until that rainy night, a desperate girl knocked on his door, holding in her hand a product proposal that had been rejected by seventeen companies. Lin Mo looked at the pattering rain outside the window and tapped his fingertips three times on the table. "At eight o'clock tomorrow morning, come here with your products and all your belongings." He didn't know that the case he took on this time would turn the table of the entire industry upside down.
