As Sukuna in Invincible - Chapter 47: The Mad Emperor

The century long war had just ended and humanity had managed to get their hands on alien technology, sending them years ahead in terms of technological advancement, fulfilling their hope of finding life outside their planet and their desire to dominate these extra-terrestrial existences. The effects of their technological advancement alone wasn’t capable of giving this result.The appearance of mutations which granted supernatural powers among humans was another boon giving them the chance to act out their darkest desires.Their joy took a dark turn when it was revealed that they were nothing more than livestock to the mysterious race, Xillthars, who cultivated them to that level. Like fattening livestock.Shortly before this dark turn of times was a forbidden creature, Kieran who had been born into the lowest levels of a society created by the greed of humans. To him, life had always been hard, but things got worse after the arrival of the Xillthars as he found himself on a trail of shocking discoveries about himself and the world around him.

“F**K! I'm dead!”That was the first word I muttered after regaining my memories from Earth.Reincarnating into a world of cultivation should’ve been a blessing. Adventure, immortality, power—what’s not to love?But then I remembered what my family did.My sister just broke off an engagement with a crippled young master—definitely a future protagonist.My mother ripped a Dao Bone from my cousin and gave it to me—guaranteed future revenge arc.And me? I’m already a third-rate villain: bullying weaklings and flaunting my Bai Clan name.Worst part? Despite the Dao Bone, I’m still trash at cultivation.My only hope?The System... which I’ve had for years.“I just never realized... It was in English!”
