Siheyuan: Sending Bang Geng to Prison and Driving the Jia Family Mad

[Siheyuan + Under the Zhengyang Gate + System + Feel-Good Story + Putting the Bullies in Their Place + Myriad Worlds + Crossover] Li Rui transmigrates into an era where Siheyuan and Under the Zhengyang Gate have merged. A battle-hardened soldier, he returns to the courtyard after being wounded in the line of duty. He investigates enemy spies both openly and covertly, serving his country in a different way. With the System at his side, he enjoys a comfortable life. Jia Zhangshi lets Banggeng steal his things and even tries to poison him. Li Rui can't be bothered to argue. He calls the police instead. Banggeng goes to prison, and Jia Zhangshi gets a stern “lesson”! Yi Zhonghai tries to guilt-trip him with moral obligations, but Li Rui won't indulge him. So what if there's scheming and infighting in this little courtyard? In the face of his overwhelming strength, it all means nothing!
