In the first year of Wude, Li Jundu, the second son of the Duke of Tang Dynasty, was born.
Others only think that the second young master is a weirdo with a mysophobia: the food bowls and bowls must be boiled in boiling water, and the swaddling clothes must be changed three times a day.
No one knows that this is a modern engineering doctor who is using the most primitive method to build his own moat.
It's better to go slowly than to go wrong.
When he was seven years old, Li Jundu personally dropped the first hardwood pillow in the Tang Dynasty on an abandoned post road in Taiyuan.
Meanwhile, historians of the modern world are going crazy.
Looking at the unearthed railway tracks from the Sui and Tang Dynasties, blast furnace ironmaking sites, and even mottled copper rulers with the word "measurement" written on them, modern people fell into collective contemplation:
"Physics no longer exists? Why did the Tang Dynasty introduce steam trains on the eve of Zhenguan?!"
When Li Jiancheng was still wooing powerful officials, Li Yuanji was still secretly setting up an ambush.
Li Jundu pointed to the railway track on the map and smiled gently at Li Yuan:
"Father, my son and minister are not talented. This road... Has been built to the gate of the Turkic camp."
