In his past life, Lu Chuan yearned for a life of luxury, but in chasing success he missed out on many important people and moments. Returning to his college days once more, he decides to seize the opportunities brought by demolition and take a down-to-earth path to entrepreneurship. As they spend time together, Lu Chuan unexpectedly discovers that his seemingly ordinary roommates in Dorm 504 all come from remarkable backgrounds: Han Dong, the avid gamer, hails from a well-known family in Northeast China; the calm and taciturn Zhao Yifan is heir to a major corporation; and the flamboyant Chen Zi'ang has a unique upbringing of his own. Relying on his foresight and wealth of experience, Lu Chuan gradually earns his partners' recognition, integrates a specialty farming supply chain, and connects with overseas partners.
