Brother Corpse: the System Asked Me to Be More Enthusiastic, Why Are You Running?

My name is Zhang Mancang. When I woke up, I was blessed with the system. My talent is [Gudao Rechang]. As long as I am passionate about people, I can absorb all harm and can continue to upgrade. But the world is in chaos, and the streets are full of zombies. The only people I can treat with enthusiasm are zombies that bite people when they catch them. But luckily... I'm a zombie too.
