Fantasy, How Can My Villain Play Without a System?

(Villain + Domineering + Ruthless + Invincible + Strategic + No System) I, Gu Tianxing, the villain of destiny, There is no right or wrong in this world, no absolute evil, and no false goodness. Those protagonists who soar to the sky with the system and the golden finger are the ones who destroy the rules of heaven and earth. "Gu Tianxing, you devil, we are from the same hometown, both from Blue Star, yet you want to harm me. Have I ever offended you?" Xu De roared angrily. He came from Blue Star and had a system in him, but now he was about to be skinned alive by the young master of the Gu family, just because the other party had taken a fancy to his system. "Gu Tianxing, you killed thirty of my disciples. I, Zhang Xuan, will never tolerate this injustice against you." Zhang Xuan shouted at the top of his lungs, his eyes filled with hatred. In his mind, a space of academy was rumbling and spinning. "Gu Tianxing, I, Li Fan, do not care about worldly affairs, but now I am invincible in the world. Do you, Gu family, really want to oppose me?" Born invincible, Li Fan was trained by the system for a thousand years. When he left, the system told him that he was invincible. One morning, a man named Gu Tianxing walked into his manor. "Why? There is no reason. Now that I know it, I cannot ignore it. I don't need any reason to deal with you. If you want to talk about right or wrong, it's just because I was born in the Gu family." Gu Tianxing looked silent. In this chaotic world, he had no system and no golden finger.
