Shen Mu, a top engineering student from the modern world, transmigrates into the Great Wei dynasty as the impoverished illegitimate son of the Duke of Zhenguo’s household and activates the Infrastructure Panel System. By completing construction tasks and defeating enemies, he earns points that he can use to exchange for items such as a cement formula and improved farming tools, or to win modern construction technologies and talent cards in draws. Starting with the management of a village, he builds waterworks and city walls, establishes academies, and develops industry, gradually transforming backward Great Wei into an infrastructure powerhouse. Along the way, he counters the oppression of the hypocritical chancellor Wei Hong, the schemes of his jealous cousin Shen Yan, and the betrayal of his corrupted friend Han Qing. With his quick wits and the System’s help, he overcomes each crisis, eventually unifying the Central Plains and founding a new dynasty, bringing his infrastructure blueprint for “Great Unity under Heaven” to life.
