Underworld King Set, the Sudden Appearance of a Rank 9 Mutated Soul Body

As long as the inner shell and Core Magic Arrays were undamaged, the outer shell could simply be replaced.

In the perilous Underworld, such a design might actually be more practical.

Huo Yutong continued carving with meticulous focus.

The Peak Rank 9 Soul Tool she was working on was undoubtedly unprecedented in its difficulty.

Eighty-one Micro-carving Sub-arrays and twenty-seven Mother Arrays were linked together to form nine large Core Magic Arrays, nested within one another.

This required the eleven Core Magic Arrays in every set to be completely error-free, while their corresponding inner-shell components had to be carved in one uninterrupted process.

Only terrifyingly powerful Spiritual Power could possibly support such a feat.

The Hongchen's Blessing made by Jing Hongchen had used only twenty-four Micro-carving Arrays, and it had not even been formed as a single piece.

Perhaps throughout the entire Douluo Continent, only Huo Yutong, with Spiritual Power at the middle stage of the Divine Origin Realm, could accomplish this.

Metal fragments continuously fell away as one Core Magic Array after another took shape beneath Huo Yutong's hands.

The materials of the parts being carved were constantly connected, fused, and replaced.

Snow Empress began testing the completed components one by one, injecting them with Spiritual Power and minute amounts of Soul Power.

Judging from the faint flickering light and the distinctive hum of the Core Magic Arrays, the results were gratifying.

The carving had succeeded in one go, without a single mistake.

Nearly four hours passed before the first set of inner-shell components and Core Magic Arrays was fully completed.

Huo Yutong showed no intention of resting. The work continued.

The second set was twice as difficult as the first, its complexity skyrocketing.

As the process stretched on, Huo Yutong felt herself growing increasingly fluent in the work.
