Thin Air?
Patriarch Ember had been allowing his subordinates to monitor the situation around the disappearance of the Awoken Moon Sect for several decades already. In truth, he had been monitoring them even before this because of this thorn he had had in his heart.
To Ryu, this matter had only occurred two or three years ago, but to Patriarch Ember, it had already been hundreds and yet he was still holding onto such a grudge. It could only be said that the matters of that day had become his own heart demon and the truth was that it wasn't entirely because of Ryu.
Of course, back then, Patriarch Ember had tried to stop Ryu from leaving the tournament using a dome of fire. But, due to the flame immunity Ryu's Rebirth Flame gave him, the low level flames of the Ember Clan couldn't even touch the hem of his robes if he didn't want them to, quite frankly. As a result, he had been able to escape that day after killing an Apostle.
