Red Mansion: a Concubine Trained His Body to Guard the Border and Was Awarded a Title.

Jia Xi, the concubine of the Rongguo Mansion, was neglected since childhood, but he inherited the soul of a modern time traveler and the "Physical Refining Technique". He bid farewell to his loyal servant Chaodou and joined the army at the border. He destroyed the Jurchen grain and grass at night and poisoned the enemy's livestock with a thousand pounds of supernatural power. He became famous in one battle. From a sixth-rank lieutenant to a first-class viscount, he watched a transparent bastard counterattack the court and rewrite the fate of the Red Mansion.
