Everyone has just practice the edited version of the grafted hands June brought out, the technique shock the lot to the bone, how come he was able to edit the technique in such a short amount of time and was able to remove the draw backs, from the new technique they won't have to be giving their cultivation up permanently, but instead temporarily, second if anything is to happen to the beast or weapon used the cultivation stored in it will return to the original owner, the down side is that both sword and user won't grow until the technique is cancelled by destroying or killing the beast or weapon used. So its a temporary used of the original technique but still it got them lost for words, to write a technique is extremely difficult, editing one already written is even fare difficult but here with a couple of minutes Dio had done what seem difficult like is was nothing.
