The spiritual energy near Frost Feather City began streaming towards Lu Xun and Ye Sui'an at an incredible speed. This tumultuous surge of spiritual power whirled around them, forming a vortex, which they promptly absorbed.
Theoretically, Ye Sui'an, who was already at the peak of the Third Realm, was on the verge of breaking into the Fourth Realm.
This couldn't be classified as a minor breakthrough; his strength was about to take a monumental leap.
Thus, the nature's spiritual energy he stimulated was extraordinarily robust, and the vortex of spiritual energy was also exceptionally massive, looking quite impressive.
The players were initially astounded, as they too could sense the flow of spiritual energy. They never imagined that Ye Sui'an could reach such a level!
This guy was astounding!
However, the scene significantly altered the moment Lu Xun clicked on [Upgrade].
While Lu Xun had only leveled up from 38 to 39, the number of experience points he'd needed was vast!
