Lu Yan is a time traveler. In his previous life, he was the best project manager of a real estate company. He is proficient in cost control, schedule management, risk assessment and blame-shifting skills. He always remembers how to leverage the maximum resources with the minimum labor cost, and how to "split the accountability nodes" of a project that seemed destined to die so that all parties involved would obediently spend money to solve the problem. After coming to Daliang, a dynasty with redundant officials, rigid hierarchies, and widespread corruption, the first thing he did was to use his "workplace survival skills" from his previous life to record the examination results of officials in the Ministry of Personnel Archives, turning it into a "promotion path map" comparable to the modern OA system. He has no system, and his "golden finger" is the thinking mode of "managing a big country as a company."
