History student Su Xian and "Shovel" Liu Yun accidentally traveled to the puppet Manchukuo in 1932 while excavating battlefield ruins.
From the undercurrent of power in the Xinjing Palace to the hell on earth of the group tribe, this originally cynical modern man and woman were forced to depend on each other under the iron heel of the Japanese invaders. Su Xian used historical knowledge to lurk in the Ministry of Internal Affairs and witnessed the signing of the "Japan-Manchuria Protocol" and the sins of the opium poisoning policy; Liu Yun struggled to survive at the bottom and witnessed the cruel truth of "using China to control China."
Without a system or a plug-in, they could not change the direction of history. They could only escape from death again and again and witness the Anti-Union soldiers eating tree bark and swallowing cotton wool in the ice and snow, just to protect their homeland behind them.
From mutual dislike to life and death support, when the prosperity came to an end, they finally understood the heaviest question of that era: Why did their predecessors die?
This is an epic about escape, awakening and redemption, dedicated to all those who walk forward with fire in the darkness.
