I Cherished And Raised The Leader Of The Evil Cult

A college graduate transmigrated into Yakseon from the martial arts novel 〈Returning Hero〉. Immediately after transmigrating, the young child he rescued turned out to be the final boss of the original work, the future leader of the evil cult.
“I will raise you.”
With the thought that he could raise the child better than the evil cult in the original work, which subjected the child to training bordering on child abuse, he boldly started a master-disciple relationship.
“I want to rip out all of their throats. Can you raise someone like me?”
“Do as you wish. Create the most cruel martial arts in the world, or do whatever you want.”
However, words that differ from his intentions keep spilling out of his stern mouth, and his disciples’ eyes roll back at the slightest mistake. He gets helplessly entangled in the glamorous past and behind-the-scenes stories of Yakseon that were not revealed in the original work.
“Master, please don’t abandon your disciple.”
The vengeful ghost finds a new object of obsession, and the original story begins amidst the already twisted flow.
