Gu Tingwei, the third young master of the Marquis of Ningyuan's household, is a notorious wastrel in the capital. His motto in life is, "A loving mother, a caring elder brother, a happy and harmonious family." That is, until one day he gets bound to something called the "Duke's Title Seizing System."
The System tells him: Your birth mother, Madam Qin, is the biggest villain in the whole book. She appears gentle and virtuous, but is secretly scheming to bring down your second brother, Gu Tingye, and put you in his place.
Gu Tingwei: ?
The System: She isn't trying to show your brother love. She's plotting against him.
Gu Tingwei: Nonsense. My mother loves my second brother most of all.
Then one day, he hears his mother with his own ears, ordering her trusted retainer in the Buddhist hall to make Gu Yanka detest this son completely.
Gu Tingwei falls silent for a moment, then reaches a startling conclusion:
"My mother is possessed by a ghost."
And so the third young master of a noble household abandons the perfectly good succession plot and begins searching all over the capital for a Daoist priest to exorcise his mother.
The System breaks down: She's your mother, not a ghost!
Gu Tingwei: What would a monster like you know about the bond between mother and son?
The System: I'm a higher-dimensional data life-form!
Gu Tingwei: So, a monster.
On one side, he has to stick talismans on his mother. On the other, he has to keep his second brother from meeting Man Niang. He must guard against his eldest brother's backstabbing and soothe his furious father. Gu Tingwei rushes back and forth between every member of the family, turning all their plans into a complete mess.
Everyone in the family is scheming against one another, while he's the only one trying to hold on to his happy little life of a kind father, a filial son, and loving brothers!
