System Transmigration: In Which the Host Torments the System

Well, this was unexpected, even for Qixi.
Transmigration? Sure.
System transmigration? Fine.
But this... wasn't this too much?
"I'm a system now?! And I need my host's Altruism Points to be human again? Pah, I need a refund of my life!"

"Hello, host! You are now contracted to the Villain to Protagonist System-"
"And who are you?"
"I am the Villain to Protagonist-"
"You really want me to work for you?"

Qixi cursed silently inside her heart. Good lord, please destroy this poor system already....
The host smirked. 'Naïve! Think you could contract me so easily?'
