I Turned Every Villain Into a Hero [Quick Transmigration]

An Ran is an emotionless elite agent of the Multiverse Management Bureau, with god-tier combat power.
After receiving a series of missions to correct diverging timelines, he sorrowfully discovers:

The targets who were supposed to become villains… all turned into paragons of righteousness under his guidance!?

He tries everything to twist their personalities toward evil, yet why are they becoming more wholesome and heroic?

He secretly suppresses his disciple’s cultivation, yet the demon lord of the dark path becomes the leader of the righteous sect?

• Senior Brother: “Master only did it for your own good.”

• Disciple: “Everything I am today is thanks to Master’s careful guidance.”

He schemes to accelerate a prince’s descent into darkness, but the undead prince becomes a wise and virtuous emperor?

• Elder Princess: “Big brother only wanted to temper you.”

• Prince: “I shall not fail Father’s painstaking efforts!”

He lets a tiny kid run wild to destroy the world, but the apocalyptic demon becomes the savior of the realm?

• Celestial Maiden: “The Venerable One taught you to restore order—brilliant job!”

• Kid: “I won’t disappoint Father! I’ll cleanse the world of evil!”

An Ran: “???”
Surrounded by over-imaginative overachievers: “I swear I didn’t mean to raise these villains into model citizens!”
