Innate Physiques

Everyone was first dumbfounded when they saw what little Kean was pointing at. Then, their expressions turned strange.

Twenty or so meters away from them, in a clear view to zombies, a figure sat leaning against a tree. 

This figure was no stranger to them as he was none other than James, the guy Luke and others had saved on the first day of the apocalypse from his apartment.

"Is he alright?" Professor Nina worriedly asked, noticing he was absolutely still with eyes closed.

Swoosh!

Luke rushed over and started checking his condition. 

Swoosh! Swoosh! 

Alice and others also arrived. They sighed in relief when they saw although it was very weak, he was still breathing.

A minute later, Luke was done with his preliminary diagnosis. Standing up, he informed them, a peculiar look on his face, "He is fine. No zombie bite, no major injury. All he has are some minor injuries and bruises that are already healing."
