Scrap Era

In the era of psychic resurgence, everyone is judged by their level of awakening. Lin Yi, a retired soldier, is officially classified as level F - he can't even touch the threshold of an awakened person. He was kicked out of the army and lived by delivering food until a D-grade awakened person struck him - that blow was silently swallowed by his body. He didn't know what he was, and the instruments couldn't detect his grade, but deep in the universe, something had been waiting for him for 180,000 years.
