Once he traveled through time, Lin Muzhi found himself in a hell on earth - the city of Yangzhou was destroyed, the Qing army massacred the city in ten days, and corpses were everywhere. He is a history teacher, full of knowledge, but he cannot save any of the dying people in front of him. In desperation, he rescued a Qing servant who was about to poison his body and die with the Qing army leader - an avenger who was more paranoid and crazy than him.
"Aren't you afraid of death?"

When he sought refuge in Nanming, he saw officials living in a state of intoxication and killing each other; when he contacted the rebels, he saw that they were fighting independently and in disarray. Lin Muzhi finally understood: on this road full of rotten trees and mud, he must first build a bridge with his own hands.
Recruiting troops, rectifying the military and political affairs, innovating firearms - a time-traveling history teacher, with a fierce woman bent on revenge, rose from the ruins of Yangzhou City. They want this blood-stained land to stand up again and the fire of civilization called "China" to never go out.
