They Forced Me to Guard the Frontier, So I Returned Home with 300,000 Cavalry

At the end of the Great Qian dynasty, the Northern Mang cavalry came knocking at the passes, and the realm fell into chaos. The Duke of Zhenguo's household, desperate to save its own skin, joins forces to force its illegitimate son, Chu Han, to take his useless elder brother's place on the frontier, sending him to the Northern Border death squad! His cold-blooded father, cruel stepmother, and hypocritical family all see him as a disposable pawn. “From this day on, I sever all ties with the Duke of Zhenguo's household!” Chu Han signs the severance deed with a cold laugh, then heads straight for the mountain of corpses and sea of blood, activating the [God of Slaughter Military Merit System]!

Three years later, the capital falls, and the officials of the court wag their tails and beg for mercy. The men of the Duke of Zhenguo's household make a disgraceful spectacle of themselves, even trying to offer the family's beautiful women to the foreign invaders in exchange for peace. At the critical moment, Chu Han returns with three hundred thousand cavalry, crushing mountains and rivers beneath their hooves! His once-arrogant father and stepmother kneel at Chu Han's feet, weeping and kowtowing frantically, begging him to remember their blood ties. With a peerless beauty in his arms, Chu Han points his blade at the powerful men of the household. “You forced me to sign the severance deed. Now that the whole family is to be executed, what are you crying about?”
