A modern architect accidentally traveled through time and became the Emperor of the Great Tomorrow, Zhu Youxiao.
Everyone thought he was obsessed with carpentry, but little did they know that he had a blueprint for a project that spanned the ages. He used structural mechanics to improve palace construction, used water conservancy planning to clear water transportation from Beijing to Hangzhou, used urban defense projects to reshape the nine-sided fortress, and used material innovation to promote smelting and military industry.
They suppressed party strife internally, purified the Ministry of Industry, strengthened border defenses externally, and appeased people's livelihood. They built a new country and country for the turbulent Ming Dynasty brick by brick and beam by beam.
