Xia ruofei and Ling Qingxue were standing at a safe distance, so they did not move an inch. They just stood there and watched the show.
Of course, Xia ruofei was also constantly forming hand seals to control the formation carefully. At the same time, he was paying close attention to the operation of the formation and the consumption of energy.
In this situation where the power of the formation was squeezed to the extreme, the consumption was quite large. The energy in the ten crystals was rapidly flowing away. It was a few times faster than when Xia ruofei was cultivating.
Xia ruofei was not stingy with his crystals and kept the array running at its highest intensity.
The thorns that burst out could not do anything to the invisible and shapeless flames.
