Lu Jin was once the sharpest cold blade in the empire. Due to a betrayal, he was exiled to the border. He was seriously injured and his heart was filled with despair. Xie Lin, the former comrade-in-arms, now holds the scepter and sits in the center, but when the enemy forces are approaching, he secretly summoned him back to the court. When foreign enemies tear apart the mountains and rivers, and civil strife ignites the imperial city, the two must put aside their grudges and rebuild the defense line with their flesh and blood. Lu Jin's sword and Xie Lin's plot are the final salvation of this broken dynasty. They no longer fight for their faith, but only to return this land - a dawn that will not be betrayed.
