On a rainy night, modern soldier Mo Guang accidentally traveled through time and became a criminal soldier who could be filled in the ditch at any time in the Qin Dynasty's supply camp.
At the beginning, the soldier's talisman was stolen, and all clues pointed to him; the officials in the camp urged orders, his fellow soldiers protected themselves, and the identity of the dead man was borrowed to guard the gate. Only Wei Heng, the female head of the household in charge of the camp, was willing to accompany him to find out this fatal frame-up starting from a broken wooden sign.
He hides a military encrypted memory from his previous life - Xuan Shu Military Box. It can see through details and deduce battle situations, but it has to pay a price every time it is used.
Starting from the military camp on a rainy night before the fall of Korea, Mo Guang survived amidst the merits of the Qin army, wars in various countries, and the undercurrent of temples. He gets to know his colleagues, counselors, craftsmen, and beauties, and relies on military exploits, strategies, and bloodshed to escape from his crimes step by step; when the Qin Dynasty overthrows and the world becomes chaotic again, he will eventually lead a group of unknown people to the far corners of the sea to establish a new country of his own.
