Siheyuan: Whoever Dares Touch My Sister, I'll Slaughter the Whole Courtyard!

[Hot-tempered big brother] [Overwhelming force] [Twist: he protects his sister] [Backed by a System]

Qin Huai'an returns to Beijing after leaving the military, only to wake up in a police station interrogation room from the start!

Everyone says Qin Huairu is a saintly white lotus, a bloodsucking monster?

Bullshit! Qin Huai'an only remembers how his sister sold her blood to buy food and dragged him back from the pile of corpses!

Remembering his gentle sister being treated like an animal by Jia Zhangshi, beaten by Jia Dongxu, and schemed against and exploited by the whole courtyard, Qin Huai'an, known as “the army’s mad dog,” laughs.

Reasoning with people? That’s the neighborhood office’s job.

With me, fists make the rules, and guns set the law!

Yan Bugui tries to take advantage of me? I’ll slap him flying!

Jia Zhangshi has a foul mouth? I’ll knock her teeth out!

Yi Zhonghai tries to guilt-trip me? I’ve got no morals, so what the hell are you going to blackmail me with?

As long as I have no shame, nobody can bully my sister!
