He transformed into the aloof and cold-blooded master in fairy tales, but found out that the original master was a scumbag with no appearance.
And he also accepted three rebels who will turn into evil in the future, and all of them have "special thoughts" about him!
The eldest apprentice is the reborn future demon lord, and the second apprentice is a swordsman wizard with a blood feud.
The third apprentice is a little junior sister who is sweet on the outside but yandere on the inside, and has a special bloodline.
The protagonist is bound to the [Rebellious Disciple Development (Fudge) System], and must prevent his disciples from turning evil, and must always beware of them attacking the master!
What's even worse is that there seems to be a fairy, the heroine of the original book, who is eyeing him. She thinks he is a hypocrite and is chasing him all the way?
Fortunately, the system is powerful, and the starting reward is full-level understanding. You can know any skill at a glance, and it can enlighten all things!
Watch how I deal with the traitor and the fairy, develop secretly, and finally become the best in the world in swordsmanship!
