Taking the Villain All the Way (Seventies)

After getting drunk, Shen Nanzui, known as “Half-Immortal Shen,” somehow found himself inside a book, as the father of a whole family of doomed villainous side characters.

In the book, the eldest Shen child was switched at birth with the factory director's son. Unable to accept it, he did one foolish thing after another and eventually lost a leg. The second and third Shen children both fell for the male lead, turned against each other fighting over him, and ruined their reputations. The fourth Shen child was the heroine's devoted admirer and did everything for her, only to end up in prison.

After learning the plot, Shen Nan said, “What a useless bunch.”

The eldest has no ambition. So what if the factory director's family is important? Just become a factory director yourself.

The second and third are even more useless. The two of you can't beat one rival? Don't give up without a fight. You have to win him over.

The fourth is a complete fool. You could be a decent person, but you insist on being a dog? Then at least grovel for someone normal.

And so, after Shen Nan arrived, the old Shen family became even more outrageous.
