After Joining the Army, I Took Down the System's Lair

Su Nian transmigrates into the most timid flag-bearing foot soldier on the Northern Frontier. Disguised as a man, she has scraped by for three years, hoping only to earn enough to eat. Then a ridiculous System keeps forcing her to save the gravely wounded male lead: save him and get paid, refuse and earn his grudge!

Clinging to a heap of corpses and pretending to be dead, Su Nian thinks: Ten taels of silver for my life? Only an idiot would do that! The first eight conquerors all ended up dead. Why shouldn't a low-level System's cannon fodder like me lie flat and stay alive?

The male lead survives and makes sure to remember the pretty boy who left him to die. But Huo Zheng, the camp's unhinged big shot, sets his sights on her instead, stealing her undershirt and blocking her tent. He kisses her breathless, then stuffs all his silver and military merit into her hands, insisting, "I'm the only one who can afford to support you!"

To protect the widows of fallen brothers, Su Nian shamelessly "plays sweet" for Huo Zheng to get resources, and somehow ends up winning the big shot's undying devotion. Even better, a newly arrived White Moonlight Conqueror tries to pay her off to leave, boasting that she'll win over both male leads and rack up points. Su Nian takes the money, then turns around and warns Huo Zheng: "Men, don't fall in love with women. It'll only make you miserable!"

Only when the System lets something slip does Su Nian realize: this isn't some transmigration conquest mission. It's gender trafficking! Women are dumped into different worlds to act like devoted fools, burning themselves up to heal the male leads. It's all a scheme by the mission designers to make money!

The timid soldier awakens in an instant, grabs her blade, and slaughters the barbarians, while tearing up her System contract. The unhinged Huo Zheng takes up his blade to protect her, the grudge-bearing male lead Xiao Jue switches sides to help, and even the White Moonlight tears off her facade and joins the rebellion.

It turns out the male leads' brothers were awakened long ago by the first-generation conqueror's mother. Everyone has been waiting to tear down the System's lair!

In a war-torn military camp, a timid soldier disguised as a man fights her way into legend and leads a host of oppressed female conquerors in a fight to the bitter end. Forget saving the male lead. This old lady is saving her own happiness!
