Moon continued to sleep even after an entire day had gone by, and showed no signs of waking up. If Lex hadn't been monitoring her with his spirit sense the entire time, making sure she was fine, he would have been extremely concerned. As it was, he was only concerned a regular amount.
Upon reaching thirty hours without her waking up, Lex, however, could no longer control himself. He fed her some extremely mild yet effective natural treasures meant for rehabilitation, and while that worked, it did not rouse her. Lex even fed her a drop of his blood, but it did nothing. There was no injury to heal.
By now, however, Lex had learned a lot about medicine. He began using various Glyphs, abilities and formations to heal and supplement Moon's body, and while that did not wake her up, she looked happier in her sleep.
