Three Kingdoms: Lü Bu's Brother-in-Law, Who Tricked Cao Cao from the Start

Ren Yun transmigrates into the world of the Three Kingdoms and becomes Diaochan's younger brother. Unfortunately, all Ren Yun wants is to lie flat. But Lü Bu can hear his thoughts. “Yuan Gonglu comes from a family of four generations of high ministers, has a thousand fine generals and wealth beyond measure. Now that he has declared himself emperor at Shouchun, an alliance through marriage could make our grand ambitions a reality!” [What an idiot! Yuan Shu won't last much longer before he's done for. If you marry into his family, Lü Bu, you'll prove you're a fool!] “Cao Cao is holding the emperor hostage to command the lords...” [What do you mean, ‘Cao Cao’? He's Chancellor Cao of the Great Han! Let us ask Chancellor Cao to send troops and punish the rebel Yuan Shu!] [The people of Xuzhou are suffering. Please ask Chancellor Cao to send supplies.] [Zhang Yang, Zhang Xiu, Cao Cao's rear is wide open. It's your time to shine!] Cao Cao: ??? Cao Ren: Damn it, Lü Bu must have a capable strategist by his side! Liu Bei: How did Lü Bu get me under his thumb? Second Brother, Third Brother, I can't defeat Lü Fengxian! Think of a way to escape! Guan Yu: Eldest Brother, Third Brother went drinking with Lü Bu! Zhuge Kongming: Though Guo Fengxiao is dead, Lü Bu still lives. I won't enter public life!
