I Have an Invincible Villain System

Miscellaneous disciple Su Yu was bullied every day and after being thrown into the deep sea, he activated the villain system. Since someone disobeys me, I will destroy his Manchu tribe! Since a demon wants to offend me, I will cut off its descendants! Since everyone obeys me today, I will destroy this day! Since everyone looks down on me, looks down on me, and bullies me; since the so-called decent families do not accept me; since you criticize me under the banner of "justice". Then I will turn grief into strength, use darkness as a sword, and fight my own bloody path. From then on, Su Yu became decisive in killing and became a "villain" in the eyes of everyone...
