Li Nantian has developed powerful force with the proficiency panel and began to sweep away the zombies.

When he faced the terrifying monster from his previous life again, he no longer panicked, but directly destroyed it with one punch! Li Nantian looked at the terrifying monster kneeling on the ground begging for mercy: Haha! That's it? Rubbish! That year he put his hands in his pockets and didn't know who his opponent was?
