The air roared, and as the two great masters fully displayed their strength, the battle between them turned out to be unexpectedly monumental.
Qingyu watched silently from a distance, observing the collision between the sword light embodying the essence of the Four Symbols and the Blood Soul Sand tide, feeling a rare trace of shock in his heart.
"It seems I am still some distance away from the true peak of the True Pill Realm."
Without using the Xuanyin Twelve Swords, Qingyu would definitely not be a match for either of the two opponents; his foundation was still somewhat lacking.
Even the previously tried assimilation reversal ability could not nullify the True Qi of the current combatants. With such a significant difference in foundation, any miraculous technique would be significantly less effective.
Moreover, Qingyu had only just started this and had not perfected it yet.
