Chapter 3721: The Crack

The rift in the ground kept widening.

More and more fragments of rock broke away from the surface, tumbling and falling into the rift below.

In the end, the crack widened to several meters across, revealing a pitch-black passage leading deep underground.

Everyone stared tightly at that passage.

Victor and the sea race showed looks of surprise.

Even the Sea Abyss region’s true age was unknown to them.

From ancient times to the present, generation after generation of sea race members had only known that a great ancient sea monster was sealed deep within the Sea Abyss. However, no one had ever discovered a passage leading into the depths of the seabed, nor were there any related records.

In fact, most of the sea race had always regarded the ancient seal as nothing more than a legend.

Victor swallowed hard, his Adam’s apple bobbing.

The passage was bottomless and completely dark.

Yet he could feel an indescribable fear spreading from that darkness, pressing down on his chest and making him extremely uncomfortable.

The three alchemists, who had been somewhat excited earlier, now froze in place and turned their gazes toward Fang Heng, their expressions filled with uncertainty.

There really was an underground passage?

He had actually been right!

Was it just luck that he happened to stumble upon it?

Feng Tiya stepped forward and used her perception. She said, "I can sense a restless dark power beneath the passage. It’s likely far more dangerous than we imagined. The legend of a sealed giant beast in the Sea Abyss may actually be true."

Fang Heng looked down into the dark passage.

A heavy coercive pressure rose from below.

Not easy to deal with.

Had the seal been damaged?

It would still take some time before he could open the Black Fog Game passage and return to the game world, so Fang Heng decided to take the opportunity to complete the mission and find the magic array that suppressed the aura beneath the seal.

Fang Heng looked at Charlene and said, "The core region of the magic array is below. Let’s go down and take a look together."

Charlene replied, "Alright."

Fang Heng nodded slightly and was the first to step into the passage.

The others followed in a single file.

The staircase leading downward was narrow and steep, covered in a thick layer of moss, clearly unused for a long time.

Fang Heng led at the front, with Feng Tiya close behind. The faint blue light of the Sea God’s Trident illuminated the path ahead.

After descending about fifty steps, several alchemists in the group suddenly noticed something and began studying the rune marks appearing on both sides of the rock walls.

"These are magic array runes."

"The structure is somewhat different from the ones above."

Fang Heng glanced at the rock walls and casually explained, "These are rune energy conduction pathways. The upper array was only a surface entrance to the entire sealing system. The real energy supply and circulation control were all handled below."

The three alchemists exchanged glances but said nothing.

It really did seem to be as Fang Heng had said.

But where did this guy even come from? How did he know so much about ancient magic arrays?

Fang Heng said, "This magic array here is not the core. No need to waste time."

At that point, the three alchemists no longer dared to object and followed silently.

After descending another hundred or so steps, the coercive pressure became increasingly intense.

Several sea race guards slowed down noticeably, struggling under the pressure. The three alchemists also turned pale, and the youngest among them had to brace himself against the rock wall just to move forward.

"Rise!"

Feng Tiya let out a low command.

The Sea God’s Trident suddenly erupted with a pale blue barrier that enveloped everyone.

Instantly, much of the invisible pressure weighing on them was cut off.

Victor let out a breath of relief and said, "Thank you, Your Majesty."

Feng Tiya waved her hand and continued downward.

Every dozen or so steps, the oppressive force grew stronger.

Even with Feng Tiya’s barrier, their progress slowed more and more.

Fana’s group of Black Castle players felt increasingly uneasy.

What exactly was the origin of this terrifying pressure?

Just the leaked aura alone created such an effect—how terrifying must its true body be?

Without Feng Tiya’s protection, the Sea God’s forces alone would have had a very hard time even reaching this point.

The group continued downward for another full quarter of an hour.

Faint wisps of Black Fog began to appear in the passage ahead.

They were extremely thin, almost translucent, slowly rising from below and flowing along the rock walls.

When the Black Fog touched the edge of Feng Tiya’s barrier, it produced faint sizzling sounds.

"Something’s wrong," Feng Tiya frowned. "There’s corrosive power mixed into the Black Fog. Be careful. Do not release mental strength casually, or it will be eroded."

"Understood."

Everyone’s expressions grew solemn as they responded and continued forward behind Feng Tiya.

The deeper they went, the denser the Black Fog became.

After descending another two to three hundred meters, the fog in the passage had already become visible to the naked eye.

Fang Heng glanced at the rock walls.

Strange.

Although the Black Fog carried strong corrosive effects, the magic array patterns on the walls remained unaffected after long exposure and were still operating normally.

Upon closer inspection, the Black Fog seemed almost alive, clinging to the surface of the runes and slowly writhing without actually corroding them.

The runes also showed no rejection or purification response.

They were actually coexisting.

Why?

"It looks like we’ve arrived."

Fang Heng raised his head and looked forward.

They had reached the end of the staircase, and an underground space appeared before them.

Everyone stopped in their tracks.

The Black Fog filled the entire underground space like thick ink, constantly churning and surging.

The light from Feng Tiya’s Sea God’s Trident could only extend less than ten meters, flickering intermittently—sometimes swallowed by the fog, sometimes piercing through it.

Through the faint light, the ground and walls of the space were covered in dense magic arrays, far more complex than those seen earlier at the bottom of the Sea Abyss.

The arrays were layered upon layer, interlocking and nested together like a vast web spreading from beneath their feet to every corner within sight.

It was over.

The three alchemists felt their scalps tingle at the sight.

The complexity and strength of the arrays in this hall were several times greater than before, far beyond their expectations.

And yet they couldn’t even decipher the ones outside...

Fine.

They exchanged glances and saw helplessness on each other’s faces.

Charlene was also somewhat surprised.

Her attainment in alchemy had already reached demigod level, but the scale and complexity of the magic arrays in the hall completely overturned her understanding.

Ancient-era alchemy...

It seemed to be a path entirely different from the one used in the present day.
