Chapter 599: Experiments

"An undead… we've been calling them walkers for a while, they don't look like Jiangshi. Since they look…natural, in their extraordinariness."

"Yes, once it's closer to morning hours, they burrow back deep into the sand and then just disappear," he said.

"Disappear? How can they just disappear?"
