The Hollow Zone (Dropped)

A man dies due to a earthquake and gets transported to a place where he thinks is "another world." Here he discovers that his species of creatures in this new world gets stronger the more they hunt and eat creatures to the point where their physical and mental form are enhanced. A month in this new life he sees humans, discovering that he wasn't in a new world but in a area on earth that was revealed thanks to the earthquake. Will he turn on the humans leading swarms of creatures to attack them or will he side by them and help them in this new world.

(Hi, this is the author as you probably can see this novel has been dropped due to a major reason that impacts this novel, I do not know much about animal biology. I'm keeping the chapters up so authors who wish to use my novel as a inspiration could do so.)
