Eerie Revival: A Monster Ate My Brain

[No System + Not Scary + A Little Brainy + Vast Worldbuilding + Slow Burn]

A monster ate Zhang Lingyang's brain.

Now he's a corpse that can think and walk.

Corpse spots are spreading, the army is outside, and the monster inside his head is snarling with hunger.

The only way to survive: devour! Devour the eerie to gain strength, devour enemies to make up for lost life!

Starting today, he is a walking catastrophe, the end of all things eerie.

"I've lost everything, but now I can eat anything."
