It seemed that perhaps due to being hasty, or due to not having enough Soul Power, Tianlong Yun's Soul Clone had made some mistakes on the net he had cast.
Finding his way out, the 'Conscience' of the Sickle immediately made a run for it, as it used it soul thirsty and murderous aura to make a path for itself.
Just like liquid finding an empty channel, the Conscience of the Sickle ran out of the net that was cast upon it, and it was finally free to deal with its target.
