Shi He, a modern engineer, was a scholar from a poor family who traveled through time and became the fictional dynasty "Da Sheng". He accidentally got involved in the court because of a paper on flood control strategies. Faced with the critical situation of powerful enemies in the north and internal corruption, he abandoned empty talk and resolved the situation with concrete actions. With modern knowledge, he started from the barren county in the north where he was assigned, burned cement to build a fortified city, modified agricultural tools to develop water conservancy, set up workshops to promote trade, and built a dead land into a prosperous "New Taipei Prefecture". His success touched the vested interest groups headed by Qian Yong, the Minister of Household Affairs, and launched a series of overt and covert attacks. The prince appreciates his talent and fully supports him, while the beautiful and mysterious eldest princess also frequently shows her favor. When Shi He rose through the ranks thanks to his achievements in infrastructure construction and became a new man in the court, he gradually discovered the conspiracy behind the eldest princess's glory and the deep-seated helplessness of the old emperor's acquiescence in his reforms. On one side is the grace of acquaintance and dynastic orthodoxy, on the other side is the subversive truth and a possible better future. Shi He has the technology and people's hearts to change the era. His choice will determine whether this land will move towards new life or fall into deeper war.
