Many thanks to our friend 9想看 for the tip. Jiaoshou was immensely grateful.
The holy fire of the Ashbringer did not have the expected effect on the source of the Sunwell's corruption. Instead, the roaring holy fire seemed about to go out. Anyone who saw this would have thought the attempt was headed for failure.
Only Rex, who wielded the Ashbringer, knew that this was not yet the weapon's true power.
The surging Holy Light within him began pouring into the Ashbringer. The Eternal Flame on the weapon in his hand began to spin, and the holy fire that had nearly gone out suddenly leaped up and erupted. Rather than fading, it burned even more fiercely than before, while the source of the corruption hissed incessantly.
The first Eternal Flame spun, followed by the second and then the third.
The three Eternal Flames spun together, stirring the motionless Golden Crystal as surging Holy Light poured into the Ashbringer.
A mighty soul pressure radiated from Rex and swept in every direction. He had begun unleashing his full strength. Standing nearby, Kael'thas reacted swiftly as soon as Rex released his soul pressure. He unleashed his own to resist Rex's, keeping it from affecting the mages casting spells in the distance and causing unforeseen dangers that might collapse the Magic Circle.
With Rex unleashing his full strength, the Golden Crystal on the Ashbringer finally responded and began rotating slowly. Compared with the Eternal Flames, it turned very slowly, but the effect it produced was astonishing.
Only when the Golden Crystal moved did the Ashbringer truly unleash its greatest power. An overwhelming blaze of holy fire instantly descended beneath the Sunwell, radiating a terrifying aura of merciless, crushing might.
There was not a trace of the Holy Light's compassion in it, only pure destruction.
