Save Datang? of Course We Need to Upgrade Infrastructure

At the end of the Kaiyuan Dynasty, modern engineer Yang Shu traveled through time and became a "canal chief" whose family was in decline and was on the verge of death from a high fever. He looked at the crying victims at the embankment collapse, raised a shovel in the heavy rain, and pried open the last glorious chapter of the prosperous Tang Dynasty. From the drainage culverts in Chang'an's Twelve Hours to the fortress beacons in the Longyou desert; from the grain carts hanging on the iron cables of Shu Road to the thunder and lightning that exploded in the sky at Tongguan. Yang Shu used the engineering wisdom of the 21st century to fight a bloody path between An Lushan's cavalry and Yang Guozhong's poisonous plan. Qiyue, the ending of the Tang Dynasty I want to show you should never be what the historian wrote!
