A doctor of history traveled to the late Southern Song Dynasty.
At the beginning, both of his parents were dead, he was in debt, and he couldn't even afford a steamed bun.
But he holds in his mind the knowledge of eight hundred years in the future.
The Jin Dynasty was going to fall, the Mongols were coming, Duanping was going to be defeated in Luo - he knew it all.
While others were still mourning, he had already borrowed money to open a warehouse.
Others were still observing filial piety, but he had already taken firearms to the military camp.
While others were still talking on paper, he had already used improved gunpowder to blast away the Mongolian cavalry formation.
Three battles were fought against Guangzhou, and two battles were fought against Luzhou.
From an orphan in a border town, he became an envoy to Huaixi with 20,000 elite soldiers and command of ten states.
From a martial artist who was despised by civil servants to the last backbone of the Song Dynasty.
But he wanted more than that.
He wants to stop the iron hoof, let the mountains and rivers revive, and let this land no longer be trampled by foreigners.
Let China become an empire on which the sun never sets!
