Ten years ago, Lin Yuan, the commander-in-chief of the Zhenbei Army, was falsely accused of collaborating with the enemy, and the blood of 100,000 soldiers was spilled on Hunpo. He escaped by chance and lived anonymously in the marketplace.
Ten years later, the barbarian cavalry went south, and the imperial army collapsed at the first touch. With no one available in the court, the emperor had no choice but to kneel down and ask the general who had been destroyed by his own hands to come out.
Lin Yuan is back. With the old injury of coughing up blood, with the debt of 100,000 dead souls, and with a secret that no one knows - it was the border defense map that he was forced to leak back then, which made the barbarians unstoppable. What he wants to save is the country that he has overthrown with his own hands.
Is this an atonement or a revenge? When the truth emerges and his enemy kneels in front of him, he must make a choice: let the emperor pay with blood, or let this precarious country survive?
