My Sister Is Seriously Ill and After Turning Black, I Will Become a Butcher in the World.

[Completely blackened + Not a Holy Mother + Villain + Live broadcast to punish scum + Never forgive + Cruel and bloody + Suspicious system] No heroine! ! ! The younger sister who has been dependent on each other since childhood "accidentally" turned into a vegetative state? Looking at my sister on the hospital bed covered in bruises, damaged organs, and blunt injuries to her skull... Mo Yu's hair turned gray overnight. On the verge of despair, Mo Yu accidentally learned the truth of the matter. From then on, he danced with the devil and embarked on a path of no return... A scumbag bully, a harsh judge, a teacher with a human face and an animal heart, a criminal who claims to be a genius... The world is sick and needs someone to heal it. Since he is being bullied by others, Mo Yu is willing to raise his blood-stained butcher knife against the scum and become a real devil on earth! (Ps: Everything in this article is fictitious. The world and characters are the fictional parallel world Blue Star. Please do not bring it into reality.) [If you don't like the introduction content, please avoid it in advance, thank you]
