Demon God Contract: I Slay My Way Across the Stars with the Evil-Slaying System

Outer-realm Demon Gods descend, and a demonic light shines across the globe, turning every human into a demonic cocoon.

Grow stronger! Take revenge! Plunder! Survive!

The Demon Gods whisper.

The day humanity breaks free of its cocoons, the world will descend into chaos and civilization will perish!

Tang Shan, an ordinary young man, seeks revenge for his girlfriend, but is ultimately dumped in a trash can in a deserted alley.

When the Demon Gods descend, he earns the favor of the Demon God of Revenge and embarks on a journey of vengeance.

If there is no good, how can there be evil?

Tang Shan says: My fists are plenty hard, too!
