Along the way, the group advanced with unstoppable momentum.

Sarah was in charge of luring monsters, Miranda handled casting spells, and Octo took care of finishing them off... sitting atop Alakdo, Luo Yan hardly had to lift a finger as he watched his minions slaughter every clay golem that stood in their way!

After they had dealt with the last wave of clay golems and summoned earth elementals, the group quickly entered a relatively open area.

This place resembled a massive stalactite cave, with sharp, towering pillars linking the majestic rock ceiling, and walls nearby embedded with pink, yellow, and green quartz.

Based on Luo Yan's experience,

the appearance of such open spaces in an otherwise cramped labyrinth usually meant that something extraordinary was hidden nearby.

Especially since the environment here didn't fit with the rest of the labyrinth.

It was very likely an illegal construction!

Just like the Weaving Shadow Nest!

As expected,

while he was standing there, a creaking friction noise started coming from the shadows in the distance; soon after, a breeze infused with magic power subtly blew from the front.

"Prepare for battle—"

"Magic Crystal Nest!!!" Before Luo Yan could finish speaking, Miranda, who was floating nearby, suddenly let out a shriek.

A pair of eyes quickly turned towards him.

"Magic Crystal Nest?" Luo Yan frowned slightly, gazing at Miranda, "What is that?"

"A type of magic crystal mine that naturally exists... commonly found in the northern areas of the Ten Thousand Ridges Mountain Range, with a few in the northern marshes as well,"

Miranda's face displayed obsession as she continued excitedly, "Incredible... there's actually such a thing in the labyrinth?! Why haven't you mined it? Is it because there are too many?"

So it means a magic crystal mine?

Luo Yan sort of understood her astonishment, yet he didn't make a big deal out of it like she did and just turned his gaze toward the nearest wall.

Tiny magic crystals adorned the surface of the quartz minerals, each tiny, translucent gem akin to a diamond growing on Kimberlite.

Similar minerals were certainly not lacking in Hell.

And like other metal deposits, the mineral resources in Hell were much more abundant than those scattered veins on the surface.

However—

The magic crystal mine here was somewhat peculiar.

Especially the quartz minerals that appeared abruptly on the silicate rocks, which didn't look naturally formed at all but rather like they were artificially embedded.

Combining information provided by the Land of Nightmare, a possibility emerged in Luo Yan's mind—

This was not any vein at all.

It could very well be the breeding ground for those clay golems!

"...because, obviously, this emerged after the previous Lord Demon King died, not something that naturally existed,"

After glancing around, Luo Yan took out his wand from his sleeve, his face gradually revealing a playful expression as he continued,

"Do you feel that? The magic power fluctuations nearby."

Miranda looked at him unexpectedly.

"Isn't it normal for there to be magical fluctuations where there is a magic crystal vein?"

Luo Yan didn't answer but just pointed his wand at the nearest rock wall, releasing a scorching column of flame from the tip.

The intense heat continuously scorched the rock wall, raising the temperature of the entire cave by several degrees.

Miranda watched the Demon King, puzzled, not understanding what he was doing.

Sarah was curious as well but didn't ask further, merely lifting her arm to secretly wipe away the sweat bead on her cheek.

Luo Yan didn't explain, maintaining the scorching for tens of seconds, then lifted his wand upward and then recited the second spell.

And this time—

The fiery blaze turned into a ghastly blue frost!

Under the extreme temperature difference of hot and cold, the quartz embedded in the rocky wall instantly emitted the unbearable crisp sound of stress.

Suddenly, web-like cracks spread across them and they were destroyed by their internal stress, turning into large and small quartz shards that fell from the wall.

Seeing this, Miranda's face showed a strange expression.

The combination of fire magic and water frost magic actually managed to shatter the hard rock wall?!

What principle was this?!

Generally speaking, such rock layers buried hundreds of meters underground were even sturdier than city walls, and even mages proficient in earth magic would struggle to alter their forms.

However, more than the shocking scene before her, Miranda was more curious about why the Lord Demon King would do such a thing.

She didn't quite understand from the start,

"What are you doing—"

Before Miranda could ask, another section of the rock wall nearby collapsed!

The embedded shards, along with the twisted rocks, rolled down together, forming a humanoid monster on the rugged ground.

Sarah, who first noticed the anomaly in the darkness, had her hair standing on end, and she grabbed her twin daggers as fast as lightning.

Having already noticed the anomaly in this cave, Luo Yan was not flustered at all; he pointed his wand forward.

Not giving the monster a chance to steady itself, a bolt of bluish-green light struck the top of the monster's head!

"Death Omen!"

The ghastly green Nether Energy blasted open atop the creature's head, piercing its invincible "body" like the claw of a lost soul, tormenting its fragile spirit.

The creature studded with crystals let out a pained cry, its joints creaking painfully as it knelt on the ground.
