This was why, at that time, one could say he was passively "Devil Transformed."
If he were to initiate it himself, he truly wasn't sure whether the Demon Sealing Monument would cooperate or not.
He had thought about trying it privately.
However, if the test failed, that might have been okay, but if it succeeded, he would once again have to endure the 'aftereffects' brought by the Demon Sealing Monument, and he might even fall into a coma again for a period.
He still remembered that the last time he was "Devil Transformed" by the Demon Sealing Monument, he had not only run around the area east of the Northern Desert in a daze but had also fallen into a coma for a long time.
That time, he was lucky to have encountered Daisy Wood.
If it had been someone else, they might have already killed him out of greed for the Storage Ring he possessed.
Only by killing him would the Storage Ring automatically dissolve its recognition of its owner.
