Returning to the cave, Quinn was covered in cuts and bruises all over his body. They were healing slowly, but rather than use blood from his blood bank or the one from his small flask, he decided to let his body heal naturally as he didn't want to cause suspicion.
Fast healing could be explained via Qi, but not at the speed Quinn's body would heal after consuming blood. Doing this would make him feel hungry for later, but he would always consume some blood from the blood bank without having Chris notice, so that wasn't too much trouble.
Besides Blood now needed to be rationed, otherwise Quinn would be feasting on the closest human next to him, and he was sure Chris wouldn't want to be a volunteer, not without an explanation first.
"Another one added to the pile." Chris said, as he placed the clear crystal on the table. Now there were five crystals of the same clarity next to each other.
