In terms of fundamental power, the Phoenix's two primordial spirits were not as strong as the Endless Flame Cage. Even if the quality of your Immortal Essence was now no worse than that of an ordinary Quasi-Emperor, it remained the same.
After all, Lord Yuyan had already cultivated to become a Star Sea Quasi-Emperor. The quality of his own Immortal Essence and Shi Yuan Quasi-Emperor's could be described as worlds apart.
But just as there were differences between people, there were also gaps between supreme treasures. Even though both were supreme treasures, the Phoenix Primordial Spirit was not something the Endless Flame Cage could compare to. The Phoenix Primordial Spirit had once been an eight-ring Dao-grade "True Supreme Treasure." Even though its grade had now fallen, it was still beyond comparison with a supreme treasure embryo like the Endless Flame Cage.
A camel starved to death was still larger than a horse. After repeated comparisons, the Endless Flame Cage was instead suppressed by the Phoenix Primordial Spirit. The Phoenix Primordial Spirit's only weakness was likely its inability to sustain a prolonged battle, especially since combat of this level consumed an enormous amount of its energy.
Fortunately, the Northern Lands' defenders held the advantage of terrain. What they feared least was a drawn-out battle; a quick battle and swift victory was instead what Lord Yuyan ought to have considered.
Yet now, let alone ending the battle quickly, Lord Yuyan had no choice but to fight you head-on after the Snow Emperor blocked his retreat.
The close-range combat strength of a Quasi-Emperor-level body was exceedingly terrifying. If he could not promptly widen the distance, then even though Lord Yuyan himself was a Star Sea Quasi-Emperor lifeform formed from top-tier fire elements, he could still perish...
Not even half an hour had passed
