Behind him, a brand new phantom of a Law Body slowly coalesces.

Its entire form displays a profound and serene indigo, seemingly composed of the purest deep sea Profound Ice and boundless ocean water. Its face mirrors Xu Guang's precisely, yet carries an ancient, unchanging calm and authority.

On its head rests an Emperor Crown formed from endless waves, while wearing an imperial robe of mysterious dragon water, countless aquatic shadows seem to swim upon the robe, tides rising and falling, embodying the Dao of Water.

This is—the Black Emperor Law Body!

With the formation of the Black Emperor Law Body, Xu Guang immediately feels his perception and mastery over Water Attribute rules reach a new realm.

In this mystical sea, he is like fish in water, the heavy and icy ocean no longer just an obstacle, but an extension of his power. The water transformations within the Residual Rain Divine Power become more exquisite.

With a subtle move of his mind, the Black Emperor Law Body merges into him, as he attempts to control the surrounding sea water, feeling it respond like an extension of his arm, forming a "Sea Domain" that belongs to him.

"Congratulations, it seems you've gained quite a lot." Yan Ruge's voice comes from outside the hall, as she enters, her face still somewhat pale, but her eyes returning to their past brightness and wisdom, evidently her wounds have healed significantly.

She observes the vast vapor around Xu Guang, which hasn't completely settled, with a trace of astonishment in her eyes. Xu Guang's speed in condensing the Law Body and the aura after success far exceeds her expectations.

"I have gained a little." Xu Guang restrains his aura and stands up, "How's your research on the Forbidden Technique outside?"

Mentioning the Forbidden Technique, Yan Ruge's expression turns more serious: "Extremely ancient and complex. The core of these Forbidden Techniques wasn't set up by people, but seems like... naturally formed by the heavens and earth, or perhaps, formed by the Dao rhythms and rules of some immensely powerful existence that fell or slumbers."

She points her hand towards the depths of the palace where chaotic lights and talismans flow: "I suspect that the entire mystical sea might be an incredibly large natural Forbidden Technique, or... a prison.

And these seabed palaces might be relics of a civilization sealed here long ago, their existence somewhat affected and assimilated by the origins of the mystical sea's Forbidden Technique."

Xu Guang hears this, feeling shaken within.

If this is true, the origin of the mystical sea might be even more astonishing than he imagined. To seal an entire civilization's relics along with its earth veins here, forming such a vast dead zone—what kind of great power would this require?

"Is it possible to find a way to use these Forbidden Techniques or find a weak spot to leave?" Xu Guang is mostly concerned about this issue.

Yan Ruge shakes her head, then nods: "Completely breaking these in a short time is impossible. However, I discovered a pattern in these Forbidden Techniques—they seem to be... absorbing the chaotic, lifeless energy in the mystical sea, and 'purifying' or 'transforming' it to some extent.

If we can locate the nodes of energy flow within the Forbidden Techniques, we might temporarily shield or even simulate similar auras to deceive the perception of the mystical sea, and find a way out."

She pauses and looks at Xu Guang: "However, this requires extensively searching these deep-sea ruins, and it's extremely dangerous. If the Forbidden Technique backlash is triggered, we would be annihilated in an instant."

"It's better than waiting for death." Xu Guang's eyes are resolute.

The two reach a consensus to leave this temporary base and search for other seabed palaces with similar forbidden techniques, hoping to find a pattern.

Xu Guang walks out of the palace, spreading his Divine Thought, finds no demons dispatched by the Profound Turtle Demon King.

This surprises Xu Guang somewhat.

However, as soon as they stealthily leave the palace's Forbidden Technique area, before going far, three strong Demon Qi lock onto them from different directions!

"Found you!"

"Prepare to die!"

Amidst the roars, three demons with varying forms of Nirvana Transformation emerge from the water, exuding murderous intent.

One is a giant crab demon general brandishing massive pincers, another a ghost-faced jellyfish spewing toxic mist, and the last one a swordfish demon wielding a bone fork with astonishing speed.

Xu Guang's eyes turn cold—it's a good opportunity to test the power of the Black Emperor Law Body!

He steps forward, the Black Emperor Law Body instantly merges with his core, his surroundings flare with indigo brilliance.

"Suppress!"

With a press of his hand, the surrounding seawater suddenly becomes exceedingly heavy, like turning into thousands of feet of Profound Ice, the enormous pressure causing the movements of the three demons to slow, especially the speed-reliant swordfish demon, as though trapped in amber.

The giant crab demon general roars, its massive pincers releasing a deathly white light, attempting to tear through the water pressure.

The ghost-faced jellyfish spews a large amount of dark green toxic mist, corroding the seawater.

Xu Guang's expression remains unchanged, his mind moves again.

"Residual Rain!"

Centered around him, the seawater suddenly rotates, transforming into countless blood rain. As the blood rain descends, it forms a giant dark vortex.

The dark green toxic mist is instantly swept into, diluted, and extinguished by the vortex.

The giant crab demon general and swordfish demon find themselves involuntarily drawn in the vortex, unable to stabilize their positions.

At the same time, Xu Guang pinches his fingers into a sword gesture, a ghostly indigo sword energy condensed with the power of the Black Emperor's origin shoots forth silently, yet faster than lightning.

"Poof!"

The sword energy directly pierces the core of the ghost-faced jellyfish still struggling, its massive body jolts, then collapses as if drained of all strength, dark green blood staining a small patch of the sea.

The remaining two demons are horror-struck, preparing to flee.

But would Xu Guang give them the chance?

The Black Emperor Law Body maneuvers the Sea Domain like a field, his form blurs, like a phantom in the water, appearing behind the giant crab demon general, his indigo glowing fist smashing hard against its hardened shell.

"Crack!"

Filled with the Power of Nirvana and the water's shock force, the fist's force penetrates the body, causing the giant crab demon general's massive frame to tremble violently, its shell shattering, internal organs instantly turning to mush.

The last swordfish demon is scared out of its wits, desperately burning demonic power trying to break free from the water domain's constraints.

Xu Guang doesn't even look, reverses a finger.

A fine water line separates from the vortex, as if possessing life, outpaces and winds around the swordfish demon's neck, gently tightening.

The swordfish demon's forward motion halts abruptly, its head parting from its body, eyes still harboring utmost terror.

In an instant, three Nirvana-transformed demons all meet their doom!

Xu Guang disperses his Divine Techniques, the sea water returns to calm. With a clasp of his hand, he retrieves the fragmented souls of the three demons, directly utilizes the Returning Collection Divine Technique, the blood sun turns into a grindstone, grinding the demon souls into dust, extracting fragments of memory from the grindstone naturally.

A flood of memory fragments pours into his mind, mostly chaotic scenes of slaughter, but soon some key information is captured by Xu Guang.

"Dragon Race... Order... Sea Domain's Demon Kings... Kill Xu Guang..."

"Sea Domain... belong to the Sea Tribe... All Demon Kings must obey commands..."

"Information transmission... via... Sea Eye Altar..."

Xu Guang's face turns exceedingly grim.

He releases his hand, causing the fragmented souls of the three demons to completely vanish.

"What's wrong?" Yan Ruge notices his abnormality, stepping forward to inquire.

Xu Guang takes a deep breath, suppressing his inner shock, and speaks solemnly: "We're in big trouble. The Sea Tribe can communicate with some existence deep within the mystical sea, issuing orders to all demon rulers level demons to pursue me in this mystical sea—almost all powerful demons are now our enemies!"

He looks at Yan Ruge, his tone heavy: "Moreover, the Dragon Race has taught these demons how to activate the Soul Blood Pursuing Soul Order Magic Technique, making your spells ineffective."

Yan Ruge, hearing this, her face slightly chilled.

Soon she softly says, "You killed Yin Kuang. Since the Sea Tribe can communicate with the denizens of the mystical sea, the involvement of the Ling Long clan must be considerable."

This implies their situation within the mystical sea will become increasingly perilous.

She looks at Xu Guang, curious about his response at this moment.

Yet, Xu Guang suddenly flashes a smile.

"This is a fortunate thing."

"A fortunate thing?"

"I think it potentially confirms your speculation correctly, that the Sea Tribe's fallen members trapped in the mystical sea have explored numerous seabed palaces, and this might mean the so-called Sea Eye Altar could be a key node, perhaps even allowing free access to the Secret Realm. This represents that we have discovered a way out, isn't this a fortunate thing?"

Xu Guang softly says.

Yan Ruge's expression is jarred.
