Villain: Picking up Trash and Massacring the Entire Class at the Beginning

[The male protagonist is cruel] [Not the Virgin] [Killing decisively] [Violent] [Extreme revenge] There is some foreshadowing in the early stage, and it is progressive. It is not until the first classmate is killed that the intensive revenge begins. After the suppression, it is extremely exciting and violent. 13 The whole class traveled to another world, and they became the proud ones of heaven, while I was a loser who was three days late. Looking at the densely packed garbage skills, I was forced to choose [Scavenger]. They don't know that this most useless F-level skill allows me to inherit all the abandoned powers in the world. I laughed when I heard that my only friend was falsely accused and executed in the most despicable way. I know the rules of this world better than they do - the weak eat the strong. From then on, I picked up the "garbage" they disdained and turned it into the deadliest poison. My classmates regarded me as the disgrace of the class, the king regarded me as a stain on the empire, and the whole world called me "the moving disaster." Do they think they can strangle me if they join forces? Don't worry, your magical skills, treasures, lives... Will eventually become the most dazzling collection in my garbage mountain.
