If that's the case, after Zhen Xuan and the others expend their magical power, the time and cost to recover will undoubtedly increase.
Under these circumstances, they might choose to demonstrate spells with relatively low consumption to conserve magical power, which is not unreasonable.
'If my guess is indeed correct, then the spells demonstrated by the other five True Persons who follow will probably be similar to those of Elder Zhen Xuan.
To mortal eyes, it appears mysterious, but it consumes very little power and can only deceive mortals.' With that thought, Lu Yuan continued to watch.
After performing the Mirage Art, Zhen Xuan disappeared and reappeared after a short while, his figure emerging amidst a haze of rosiness.
"Fellow Daoists, that was the Mirage Art. Now, let us welcome Fellow Daoist Anqiu from the Dan Ding Path to demonstrate an immortal technique for us."
Elder Zhen Xuan smiled and saluted the audience before leaving the stage gracefully.
