As the days passed and Ai slept, the radiation storm outside continued to drench the land in radioactive particles. Mai and the rest were getting a little nervous about the amount of radiation built up in the soil. If it continued as it was, the land would become an uninhabitable zone for humans. Although they were safe underground they would not be able to leave any time soon.
Mai was also becoming worried about Ai since she could not even inject a needle into her skin anymore. Even a knife could no longer slice her skin. She had to spoon feed Ai to drink water with vitamins in it, just to keep her hydrated. Luckily Ai was reflexively swallowing it all.
