"Well, as you may know, I'm a doctor, so I used my skills to do the deed. You see, there is lysis, which means the breaking down of cells. I had the idea of creating an incredibly efficient virus. One that would not only survive, but thrive in the body of an animal, and feed off of the cell membrane and cytoskeleton of the animals cell. After enough of the cells had been devoured, the virus would breed and multiply exponentially, killing the victim very quickly indeed. With this book, I was able to refine my process and even narrow the effect to only humans." Joseph explained.
