Imperial Chief Engineer

In the eighteenth year of Jinghe's reign, Shen Yan, a minor river worker in Linhe County, was unjustly imprisoned and will be executed tomorrow. Several wells in the south of the city became muddy overnight, and the Yongning Embankment hid dangers. To survive, he must prove that the damage is enough to reopen old cases. After being tortured, another soul with the same name appeared in his body - a senior engineer from modern times who participated in the complete construction cycle of a large hydropower station. One understands county government, relationships, and account books, while the other understands engineering, standards, and risks; the two share bodies, but they do not share all memories, nor are they always the right answer. Faced with cutting corners, misaligned accounts, official shirking, and ensuing disasters, they must use the materials and manpower available in ancient times to turn scattered experience into a recordable, reviewable, and accountable engineering system. It's just that the deeper they cooperate, the faster their souls merge. As the empire gradually learns how to build, test and take responsibility, the two Shen Yans are also heading towards the end where only one person can be left behind.
