The Infrastructure Madman in the Late Song Dynasty Started by Guarding Diaoyu City

A bachelor of civil engineering from a top modern university, as soon as he opened his eyes, he became the treasure of Bozhou Chieftain in the late Southern Song Dynasty - Yang Bangxian. Before he could figure out how many mines his family owned, a bloody military message hit his face: Meng Ge, the Great Khan of Mongolia, had surrounded Diaoyu City with a hundred thousand cavalry, and was about to hit his doorstep! It is written in the history books that in this battle, the Mongol Khan would die, but the Southern Song Dynasty's strength would also come to an end. A few years later, the Yang family will have to surrender obediently. What to do? The adults in the court will only quarrel, and the generals on the battlefield will only fight to the death. In despair, Yang Bangxian opened the "heavenly book" in his mind - an introduction to urban defense systems in materials mechanics, structural engineering... When everyone thought the end was coming, he silently took out the drawings. "Don't panic." "First... Lay a foundation." This novel and its characters are purely fictitious.
