"Do you want revenge? Sign this contract at the cost of... Your soul."
Lu Chen, a senior high school student, was selected by a consciousness from the abyss and bound to the [Sin Loading System] after witnessing his childhood sweetheart being killed by a transcendent.
But there's a fatal problem with this system—it only rewards "evil behavior."
Theft, fraud, betrayal, killing... The more serious the crime, the stronger the power.
Murderers can gain the ability to teleport, traitors can gain mind control, and genocide can gain immortality.
And Lu Chen, in order to gain enough power for revenge, must go further than everyone else on this "path of sin".
But he soon discovered that the real purpose of the system was not to make him stronger.
Instead, let him become the "new Lord of the Abyss" and let human civilization be buried with him for his sins.
"If becoming a devil can protect the world, then I am the biggest devil in the world."

This is the story of a crazy young man who struggled with sin, became an enemy of the whole world, and finally decided to "fight evil with evil."
