After Xiao Shi was sent to a mental hospital by his scumbag father and stepmother, he endured years of torment before finally escaping while the guards were away.

"Hahaha! I'm finally out of that hellhole! You bastard, Dad, get ready to feel your son's lion's teeth!"

He shouted his bravado at the sky, then suddenly realized something was wrong. Why was everyone biting each other in the street? Had things gotten this enthusiastic during the few years he'd been away?

Xiao Shi tried to reassure himself, but when he saw the bloodied, flesh-torn living corpses charging toward him, he could only laugh helplessly, shake his head, and turn to run.
