Corpse Brother: The System Told Me to Be Friendly, So Why Are You Running?

My name is Zhang Mancang. I woke up one morning to find I'd gained a System and the talent [Warmhearted Samaritan]. As long as I treated people warmly, I could absorb any kind of damage and keep growing stronger.

But the world had already gone to hell. Zombies were everywhere, on every street and in every alley. The only ones I could treat warmly were the drooling zombies that bit anyone they caught.

Fortunately... I was a zombie too.
