"Boom, boom, boom!!!"
Accompanied by fluctuations of terrifying power, earth-shaking explosions abruptly shattered the peace of the Profound Yin Mountain Range.
Sensing that terrifying power, the Profound Yin Cult cultivators turned pale with horror. They abruptly looked toward Heavenly Shaman Mountain, a sense of impending catastrophe rising within them.
The only fourth-tier spirit mountain had activated its Mountain-Guarding Formation at some point-a sign that a powerful enemy had arrived.
Churning black mist enveloped Heavenly Shaman Mountain, while several tiny, brilliant streaks of spiritual light continuously bombarded it.
Those streaks of spiritual light seemed inconspicuous, yet the power rippling from them struck terror into low-level cultivators. A single glance from afar was enough to send their spiritual perception screaming warnings.
"Boom!!!"
Nascent Soul True Lords attacked with extraordinary speed and frequency. Unless one's cultivation reached a certain level, even divine sense could not follow their attacks clearly.
Heavenly Shaman Mountain's formation was indeed formidable, but with a Formation Path grandmaster present to guide them, Liu Yu and the others always struck its weaknesses precisely.
Under the bombardment of four Nascent Soul True Lords, the black mist visibly thinned after just twenty-odd breaths.
Things seemed a little too smooth.
Someone was indeed controlling the formation, but Old Monster Qingshan had never appeared. That was rather strange.
Otherwise, this formation would not have performed so poorly.
Driving the Setting Sun Golden Rainbow Spear to bombard the formation, Liu Yu watched the rapidly thinning black mist and kept feeling that things were going too smoothly.
Was the target really inside the spirit mountain?
As his hands slowly formed hand seals, the thought flashed through his mind.
With the guidance of Formation Path grandmaster Fang Chengshan, they could always locate the formation's weak points, no matter how its configuration changed.
"Bang!!!"
