He started panicking, he continue to use his powerful soul to sense his cultivation but even a hint of it is unavailable to him, his heart quickly gone cold, he realised that he might have ti cultivate once again but before he could think this, Hentai quickly informed him about his present condition.
[Master, do not be worried about your cultivation, because of the act of rebirth have an extremely harsh requirement, I had to seal your cultivation to preserve it.]
He quickly heaved a sigh of relief when he heard this, he then look below and saw everyone was still kneeling for him, he flew down and said "Everyone of you may rise."
Even though his cultivation might have been sealed, he still have to preserve the dignity of his kingdom, his aura that was tempered by all of what he experienced in this world, coupled with his overbearing soul might cause the people to feel that they aren't a match against him.
