When the formation activated, bizarre phenomena occurred within a radius of several hundred meters.
Accompanied by the shrieks and wails of Yin Souls, tens of thousands of them fused to form a blood river.
With a thunderous roar, the blood river surged downwards, its violent waves rolling in, sweeping up the atmosphere between heaven and earth.
Dust, sand, and leaves whirled up in the fierce winds as the formation rendered the illusory into reality, inflicting tangible harm and bringing terror into the world.
The mere sight of it from afar caused the disciples' bodies to chill and their souls to tremble.
For Cao Yuan and Nan Wenli, who were in the midst of it, the sense of fatal threat was even greater.
With no time for further reaction, the roaring blood river covered them, and Cao Yuan's dozen or so Flying Swords became like drunken flutterers, wavering erratically in the air before one after another fell to the ground.
