After Redeeming Three Obsessive Villains

As a new employee at the quick transmigration Bureau, Yangyang was assigned three five-star-difficulty missions on her very first day. World One. The villain was an abandoned orphan who had suffered endless hardship since childhood. One day, his mind became twisted. With his extraordinary cunning and a golden finger System, he took down the original world's male lead, leaving the world on the brink of collapse. Yangyang reached out to him and pulled him from the mire. Like a little sun, she lit up his pitch-black world, then dusted off her hands and left. World Two. The villain was born a psychopath who took pleasure in toying with lives. With his powerful supernatural abilities, he plunged the world into the apocalypse. Yangyang approached him, cared for him, and changed him with love. She saved the world, then dusted off her hands and left. World Three. The villain was an aloof, untouchable beauty. Yangyang stayed by his side as his disciple for over a decade, only to discover that he was upright and virtuous, and didn't seem to need saving. So she dusted off her hands and left. But not long after she departed, the cool and distant Immortal Venerable was overcome by inner demons and became a Fallen Immortal, a name that struck fear into everyone who heard it. Yangyang was urgently summoned back. At the Wuji Hall, the Immortal Venerable had a vivid red Fallen Immortal mark between his brows and blood-red eyes. He advanced step by step, pinning her against the table. "...Now that you're back, don't even think about leaving again." A lock talisman was driven into her wrist. Worse still, the villains from the first two worlds had also crossed over, demanding to know why she'd abandoned them. The cool and distant Immortal Venerable narrowed his eyes, his gaze cold enough to freeze someone to death. Yangyang was on the verge of tears. ...Please, can I have a chance to explain? [Reading Guide]: This is not a quick transmigration story. The story takes place in the world of the cool and distant Immortal Venerable, because he is the male lead.
