The Dead Silence Desert, due to its immense expanse and the fact that its suppressive force grew stronger the deeper one went, had been divided into several graded regions.
Overall, it was divided into the outer region, the inner region, and the core.
Even the outer region actually contained several subregions, divided into low, middle, and high levels according to the suppressive force they endured.
The low-level outer region could suppress the spiritual power of cultivators below the Immortal Lord Realm. Under normal circumstances, even peak Golden Immortals would have their spiritual power suppressed and be unable to use the spiritual power within their bodies.
Immortal Lords could resist it to some extent, with the suppressive force able to suppress at most thirty percent of their power. Immortal King experts, however, could remain immune.
Yet upon reaching the high-level outer region, even Immortal King experts would have seventy to eighty percent of the spiritual power in their bodies suppressed.
After entering the inner region, even Immortal Emperor Realm experts would suffer suppression of thirty percent of their internal spiritual power.
Moreover, once Immortal Emperors entered the inner region, they could no longer absorb the spiritual qi of the Dead Silence Desert.
If they ventured deep into the inner region, even experts at the Perfection Immortal Emperor Realm would have their spiritual power completely sealed away, unable to use even a trace of it.
As for the core region of the Dead Silence Desert, the suppression suffered there was even more terrifying. There were even rumors that once Perfection Immortal Emperor Realm experts ventured into the core region of the Dead Silence Desert, they would basically never come back out.
The Dead Silence Desert was not without value, for it contained a special kind of Glazed Golden Sand, a unique material.
