Trapped Inside A Phone

The year is 3004. The angels have long since left the world, but one who's tied too closely with the world decided to stay. Some humans had been trying for another way to achieve eternal life. They previously attempted to use angels, but they were much to powerful, and few remained.
One day, they had a break through and finally got microchips to work. Firstly with animal testing and were ready to begin human trials. A small group was chosen to be test subjects by physical build and mental strength. As luck would have it, the last angel was among them. Since the government at this time controlled everyone by fear, there was nothing poor Ryan could do that wouldn't cause a public outcry. He also believed he could get himself out if needed.
As you can see with the title, he couldn't. Follow him on his strange journey to return to his body now!
