Douluo Dalu: Villain System? But I'm the Chosen Protagonist!

Luo Baiyi transmigrates into Douluo Dalu. Because of his special Martial Soul, Bibi Dong takes him in as a disciple, and he awakens the Destined Great Villain System. He's the Spirit Hall's Holy Son, Bibi Dong's disciple, and a villain through and through. But... When he sees the first mission assigned by the System, Luo Baiyi is stunned. Steal the destined protagonist Luo Baiyi's opportunity? I'm the great villain and the destined protagonist?! Am I stealing from myself? Years later, Luo Baiyi sits high above the heavens, his sword defeating the gods. Facing their astonishment, he only smiles faintly. Fate is mine, and the System is mine. All living beings of this world shall bow before my sword!
