For now, Yi Beidou was calling this form of Demon Flame, which could stimulate his cells for rapid regeneration, the "Penglai Flame."
"I can feel it. This is probably the limit for now. It seems I've hit a bottleneck."
Yi Beidou muttered to himself.
Yi Beidou felt he still had room to improve when it came to seizing the Penglai Power to augment his own combat strength. If he spent another six months to a year studying it, it wasn't impossible for him to reach or even surpass the level of the Penglai Technique the Alchemist had once used.
At that point, as long as he was within the Penglai Immortal Mountain, he would be able to use the Immortal Forbidden Technique at will.
But that wasn't particularly meaningful.
However, when it came to transforming his Demon Flame into the "Penglai Flame" to stimulate his regenerative abilities without relying on the Immortal Mountain's Power, he had already hit a bottleneck. Further progress would be difficult.
