Avenge His Father and Return from the Army

I was originally a carefree son, but unexpectedly, something unexpected happened and my father and brother died in battle. In order to avenge my father and brother, I left a letter from home and secretly joined the army. After five years in the army, I was still a young man. I swore an oath to sit on the throne of the Nine-Five-Year-Old. Not for the power of life and death, not for the beauties in the harem, but only for the brothers who had helped me through life and death to see the light again.
