Villain: The Three-Year Deadline Is Up, and the Asura Returns from the Start

[Xuanhuan + Villain + Multiple Heroines + Not Dark] I transmigrated into a fantasy world and somehow became the big bad backed by an immortal clan? I open my eyes, and from the start, it's the three-year deadline and the Asura's return? No need to worry. I have a System. The Asura smirks, so I shut him up for good. What? You have heroines too? Sorry, they're all mine now. Go on in peace. As the big bad, I'll take charge of this world for you!
