Lu Zhao, a modern armed policeman, traveled through time and became a Tang Army scout who was branded as a "deserter" after the Anshi Rebellion.
The beginning was hell - being pushed down the slope by his colleagues, facing the annihilation of the entire army and the Tibetan pursuers, he killed someone for the first time, and was called the right name for the first time.
From the desperate attempt to save oneself with arrows, to the bloody battle in the village with an outnumbered enemy, to the thrilling espionage war in Victoria.
Relying on military knowledge that surpassed the times for thousands of years, he struggled to survive in the bloody war between Tang and Tibet for hundreds of years.
When the "biggest victory after the Anshi Rebellion" recorded in historical records began, he suddenly discovered that the copper coin that killed the entire team was actually related to the mystery of his identity.
Lu Zhao said: "The life you owe must be repaid."
But what he wants to repay is more than just his life.
