He now had 3 dragons, but before he could do anything, he felt that the ritual magic was quickly spiralling further out of control. Jon Snow's body was now revived and restored, three dragons were hatched, and he was even connected in some rather unconventional way to them. The problem was that the leftover magic was most probably about to cause either an implosion and turn everything into meat paste or an explosion and destroy everything nearby, including himself. Both results weren't desirable at all. Shuffling through his memories for something that would help him deal with such an amount of wild ritualistic magic, he realised that only using an old body refining method would be effective. Harry discovered it in a very old and well-protected tomb that predated Ancient China and used vast amounts of wild magic to refine the body.
