While waiting, Sima You Yue surveyed her surroundings and realised that the trees here were a lot lusher as compared to the ones on other mountains.
She wondered whether or not it had anything to do with that energy.
Half a day later, Supreme Fifth Spirit Senior said that the waves had appeared. Even though they were standing outside the barrier, they could sense the waves of boundless energy pulsating outside.
On the outside, it was unknown how big the energy would become. It was no wonder Supreme Fifth Spirit Senior did not bring her inside immediately.
Sima You Yue could feel the energy rippling through her body and felt that it was rather familiar. However, she could not put her finger on it.
Once the wave had passed, Supreme Fifth Spirit Senior said, "This energy is strong sometimes and weak at others. When it's strong, it's strong enough to kill two of my clansmen. When it's weak, its similar to how it is today."
