Chapter 378: Underground City of the Main Peak

The person who opened the passage seemed prepared. They immediately sent a wave of spiritual energy into the tunnel, instantly dispersing the Demonic Energy that gushed out.

Unlike the all-corrupting Demonic Energy from the Six Realms, this energy proved feeble—easily shattered by spiritual energy.

“This filth has reached here too,” the Immortal cultivator muttered darkly, urgency tightening his voice. “We must reinforce the suppression formation at once!” He strode briskly into the passage.

The other cultivators followed without delay, slipping through the ground entrance moments before its closure. You You darted forward, pulling Feng Rong and Yuan Qi through the vanishing gap.

The sealed entrance left them in a downward-sloping passage illuminated by countless specks of spiritual light—manifestations of intensely condensed spiritual energy.

All three stared in surprise. How could Demonic Energy emerge where spiritual energy thrived?

The Jingling Institute members had already vanished, likely hastening to stabilize the formation. “The spiritual light’s origin suggests a formation ahead,” Yuan Qi observed, gesturing deeper into the passage. “The Demonic Energy flows from there too.”

Feng Rong extended his hand. Strands of black energy swirled obediently into his palm. “Odd,” he frowned. “I can command this Demonic Energy.” Despite lacking his usual powers here, the energy responded to him.

“Let’s investigate,” You You decided. Minutes later, they entered a vast stone chamber dominated by a massive protective talisman etched into the floor. Cultivators sat around it, channeling energy to contain swirling black masses below—Demonic Energy tainted with pure spiritual essence.

Through Voice Transmission, You You observed, “Their four-sided formation suppresses Demonic Energy.”

“This is merely one sealing formation,” Yuan Qi noted. “It connects to others. The main peak’s depths must hold many such arrays.”

“But where does the energy originate?” You You pressed. “This world lacks demon tribes.”

“Feng Rong?”

The red-robed man captured a wisp of black energy. “There.” He pointed across the chamber to shadowed passages. They slipped past the preoccupied cultivators into a labyrinthine network—proof the entire mountain had been hollowed.

Repeated chambers revealed identical suppression formations, each tended by Immortal cultivators. As they descended, both Demonic Energy and spiritual energy intensified. Spiritual light gave way to glowing veins pulsing through stone walls.

“Close now,” Feng Rong announced. Yet You You froze, head snapping toward a side passage.

“Something called me,” she murmured when questioned. No sound existed—only a wordless pull.

“The energy source lies leftward,” Feng Rong countered.

Choosing the left path, You You felt strange melancholy brush her mind—forlorn, almost aggrieved. The corridor widened into pillared halls worthy of palaces until they reached a shattered stone door. Golden formations blazed above rubble, containing viscous Demonic Energy that leaked brilliant light.

“The source,” Feng Rong confirmed.

Within the cavern beyond, a colossal formation blazed. Golden spears of light pinned enormous White bones midair—segments of skeletal dragons still shimmering with fading draconic energy.

Bone Dragons.

The trio stared, stunned.

What madness was this?
