Survival: You Want Me, the Villainess, to Bully the Male Lead's Crew?

[Everyone's Survival] [Farming and Hoarding Supplies] [Unconventional Villainess] [Everyone Is Beautiful, Strong, and Miserable] [Self-Conquest] [Rivalry for Love]

After freezing to death in a barren wasteland of ash, Sang Qi opened her eyes and was pulled into a survival game for all humanity.

While everyone else wailed in despair at the dilapidated hollow of a dead tree and the man-eating ash fog outside, Sang Qi held the hot chestnut cakes and clean spring water she'd found in a treasure chest, her eyes welling with emotion.

How was this a survival game? It was clearly a heavenly retirement home with meals and lodging included!

But just after she had eaten her fill, an antagonist System suddenly bound itself to her mind, calling itself Judge's Brush:

[Warning! The world's four male leads blessed by fate are disabled, weary of life, and waiting to die! Host, immediately play the vicious supporting female character. Humiliate and exploit them, and use their hatred to fill them with the will to survive! Otherwise, the world will collapse, and your retirement home will be gone too!]

To keep her hot meals, the meticulous Sang Qi decided to follow the plot to the letter.

How hard could it be to play the villain?

It should be pretty easy to learn, right?
