Lin Yuan could not afford to lose such feys that could produce pure elemental energy.
The martial arts hall was large enough to hold several feys undergoing World Cleansings simultaneously. It went without saying that there was enough space.
It was perfect for Lin Yuan to evolve the Perfect Touch Wisteria here.
The Perfect Touch Wisteria's increase in power and size was definitely a good thing.
The Perfect Touch Wisteria mainly used its body during combat. The stronger and larger its body was, the more combat power would come from it.
Lin Yuan did not rush to take out another batch of spirit qi crystals. Rather, he told Begin Lady, "Begin Lady, help me watch over this space. If you discover anyone spying nearby, eliminate them immediately."
Both the spirit qi crystals and the Perfect Touch Wisteria were Lin Yuan's secret weapons and secrets.
There was no way he would allow them to be discovered by anyone.
