Cao Yang grew up in a psychiatric hospital until the age of thirteen, so his thought process is different from an ordinary person's.
Because his surname is Cao and he grew up without parents, he became obsessed with Romance of the Three Kingdoms, always thinking he was descended from the Cao Wei clan. When he went to "hunt down" his junior sister, Yang Bingyue, and take her spirit pet, she was on a blind date with a man she didn't like. To get rid of him, she took Cao Yang straight to the civil affairs bureau and registered their marriage!
The first time he meets his mother-in-law, Cao Yang introduces himself: "Greetings, Mother-in-law. Your son-in-law's surname is Cao, his given name is Ren, and his courtesy name is Zilian. I command Cao Cao's Tiger and Leopard Cavalry!" When his father-in-law invites him inside, he drops to one knee: "Thank you, my lord!"
"Catch the ghost's head! The one with the long beard is the ghost's head! Catch the ghost's head! The one in the black robe is the ghost's head!"
His junior sister doesn't want to go to a class reunion because an obnoxious classmate, Pan Lili, will be there. Cao Yang persuades her: "My lady, you should go to this reunion. You have ten advantages as a wife, while Lili has ten flaws!"
While catching ghosts: "See this bitter melon? Do you dare come any closer?" Then he whispers to his junior sister, "Empty Fort Strategy." When Guan Yu warms wine and beheads Hua Xiong, Cao Yang warms water and slays evil spirits! Invited to dinner at a tycoon's home, he looks left and right, searching for the hidden executioners!
A strategist stakes his life on the game to gain half a move over fate. The ghost-hunting stories are full of excitement, and his devoted-husband persona never wavers!
