He is the seventh prince of the Qin Dynasty, an enemy hostage, and an "abandoned son" who was thrown to Yanmen Pass to die.
The guard general Wang Biao followed the prince's secret order and threw him into the death pile, withheld food and grass, and cut off supplies. On a snowy night, the hungry and crazy soldiers were already eyeing his flesh.
When everyone thought that the prince was about to die silently at the border, no one knew that there was a military doctor from the future living in his body.
"Ding! [Da Qin Military Industry System] is activated. The host can exchange military industry points for war technology that transcends the times: steel-making blast furnaces, gunpowder formulas, repeating ballistas, and even... The black powder that is enough to rewrite the course of human civilization."
Zhao Chen opened his eyes.

In the battle of Yanmen Pass, 3,000 remaining soldiers faced 50,000 cavalry. Everyone thought he was going to defend the isolated city, but he led his troops out of the city to form an array and calmly opened the gun jacket.
