How to Win Over a Psychopathic Villain [Quick Transmigration]

As the title says, how do you win over a villain with a physical disability or mental health issues?

Why win them over? Because they're going to destroy the world!

The female lead takes a bounty mission that requires her to enter a virtual world and save ten specific villains, preventing the virtual universe, with its year-round online population exceeding ten billion, from collapsing.

Since the setting is a virtual world, the female lead's moral boundaries are flexible, and the villains really are unwell! The story is even more unrestrained and doesn't follow much logic, so it's best read without overthinking it =v=

Theme: Helping others is a joy.
