The restoration of his body was quick. His crushed bones that could be put together and fused were fused, while those that were too small or too broken were removed to make room for a replacement to grow.
His bleeding stopped. His muscles were mended, and his body was made whole again.
Finally, his discarded body parts were destroyed. Bones, muscles, skin, and many others that were removed were turned to dust.
Even the blood on his clothes and armor was destroyed. By the time the array disappeared, he was squeaky clean, and the white room had been restored to its previous cleanliness.
As things were, no one would believe that someone nearly bled to death in the room a few minutes ago.
It took a while for Arthur to become conscious and to wake up. When he did, he was shocked by the lack of pain.
Then he saw the clean room and his restored body. He was still staring in disbelief when his whole world flashed, and he was removed from the room.
