Wang Kai, a first-level cost engineer who has been working for 10 years, is also responsible for the construction and cost control of four tens of billions of projects at home and abroad. Due to excessive management pressure, he suddenly exchanged souls with "Wang Kai" who had the same name more than 2,000 years ago. Wang Kai used modern knowledge and professional ability in costing to lead the people of the feudal dynasty with backward production conditions to eat and drink well, and lead the development of the Qin State.
