Xuandu stepped into the Blood Sea passage.
Countless wrathful soul remnants struggled within the walls of blood waves on either side, yet they could not penetrate the invisible barrier formed from Hunyuan Dao Rhyme.
In the deepest reaches of the Blood Sea, even the spiritual sense of an ordinary Daluo Golden Immortal would be corroded by the filthy fiendish qi, making it impossible to endure for long.
Yet to Xuandu, this Utterly Yin and Evil Land could not shake him in the slightest.
The divine soul of a Zenith Heaven expert had long fused with the Law Origin, invulnerable to all evils.
The deeper he went, the more terrifying the water pressure became. Ordinary gold and iron would have long since turned to dust here.
The blood-red liquid gradually thickened into something tangible. All light vanished completely, leaving only eternal darkness and surging fiendish qi.
Yet the call that came from somewhere unseen grew increasingly clear.
Xuandu remained calm, his steps neither hurried nor slow.
As his green robes fluttered, filth receded and fiendish qi fled wherever he passed.
He did not know how long he had descended.
The source of that call now lay close at hand.
Xuandu stopped, standing within a void of absolute darkness.
This was the Heart of the Blood Sea, a forbidden zone that even Nether River Old Ancestor rarely set foot in.
The thick, tangible blood fiend had nearly solidified. The filth and resentful power within it were enough to corrupt a Quasi-Saint's Primordial Spirit in an instant.
Yet Xuandu's spiritual sense had already spread like an invisible net, thoroughly enveloping this entire region.
However.
His brows furrowed almost imperceptibly.
Wherever his spiritual sense swept, there was nothing.
There was only boundless blood fiend, surging deathly stillness, and unchanging eternal darkness.
"There's nothing here?"
