Undead Cataclysm!

Behind layer upon layer of undead troops.

Atop the seven-tiered altar, Huo Ling prepared a legendary spell.

Rune after rune condensed in his hands, forming sets of rune arrays as he drew upon the surrounding power of rules.

The power of rules was drawn out like trickling streams, and for the moment, it had not yet caused any changes in the heavens.

Once the power of rules in his hands had accumulated sufficiently, Huo Ling looked at the half-orc soldiers still locked in bitter battle, a cold smile appearing on his face.

Huo Ling looked toward the sky. Around him were death rules like chains. He seized those death rules, wove them into completion, and then released them into the heavens.

An immense magical pressure rose from Huo Ling's formation at that moment. The power of rules he had drawn upon was activated, swiftly drawing in even more power of rules.

The spell in Huo Ling's hand shot into the sky like a dazzling beam of light.

A heavy death cloud rapidly formed in the sky, still expanding at tremendous speed.

Like billowing black clouds, the death cloud surged unceasingly with the power of rules, occupying the vast sky as the spell's range continued to spread.

Below, Huo Ling continuously drew upon the power of rules to reinforce the spell. The rune array of the legendary spell itself was also drawing upon the power of rules.

Under such reinforcement, the entire battlefield had already been shrouded beneath this spell cloud.

And it was not over yet. The cloud continued expanding its range, and the wider it spread, the faster it expanded.

Huo Ling, standing on the altar, calmly drank a vial of potent mana restoration potion and observed the fruits of his labor.

This was the legendary spell: Undead Cataclysm!
