While Fang Han was refining the "Immortal Tea Tree" in his inner world, he circulated his own divine abilities to investigate upward and saw the giant pale blue Sea Emperor form descending into the Sea Eye.

Facing this Sea Emperor form, he felt no fear in his heart, knowing that this was an evil ritual summoning the emergence of the ancient Sea Emperor's true spirit. It operated on the same principle as his Sacred Sacrifice Great Immortal Spell.

Sacrifice and summoning—these two methods had endlessly changing varieties, but the underlying principle of both was to offer souls, vitality, and lifespans to some incomparably powerful existence in the void in exchange for tremendous power.

"Fang Han, this is the ancient Sea Emperor. In the Primordial Era, he was the creator of the ocean civilization. Even before the Three Sovereigns, he ruled the ocean and even invaded the mainland. He had fought wars with the Three Sovereigns." Yan could not help but exclaim in surprise upon seeing the descent of the giant Sea Emperor phantom.

"Is that so?" Fang Han was presently brimming with energy, his entire body as fierce as a dragon or tiger. Being at the juncture of devouring and refining the "Immortal Tea Tree," his vitality was naturally abundant, his body possessing an inexhaustible strength. Even against a master at the True Immortal level, he could put up a fight. With a slight circulation of the Cangsheng Great Seal within his body, infinite vitality was input into it, making the divine beast Baixi vibrant and vigorous as well. Not only did the myriad restrictions within the Great Seal resume operation, but they operated even more intensely.

All the magical treasures were activated. Every scale on the Primordial Ancestral Dragon's body opened up, especially the reverse scales on its neck, which began to rustle.

A dragon has reverse scales; touching them guarantees death.

This was even more true for the reverse scales of the Primordial Ancestral Dragon.

The flipping of the reverse scales represented that the dragon was beginning to get angry. With strength multiplying, a violently enraged dragon was extremely terrifying.

"Great Majestic Barren Dragon! Taking control of heaven and earth!" The Primordial Ancestral Dragon formed by Fang Han grabbed at the Sea Emperor with a claw. Each scale was a hundred acres in size, carrying vigorous strength and barren aura from the very dawn of heaven and earth.

With this claw, Fang Han mobilized the world within his body. The speed at which the Immortal Tea Tree was refined became even faster; even some laws within the Immortal Tea Tree were wavering, about to be sucked into the Supreme Dragon Pearl of the Eight Divisions Pagoda.

The Immortal Tea Tree contained Heavenly Cave laws, which Fang Han himself could not refine. However, his life-bound artifact, the Eight Divisions Pagoda, could absorb them. After absorption, not only would it become more formidable, but a solid foundation would also be laid for it to become a Peerless Grade Dao artifact in the future.

At this moment, Fang Han seemed to have inherited some of the Immortal Tea Tree's abilities. His body closely integrated with the Mysterious Water Black Qi in the Sea Eye. As the pores of his body opened, boundless Mysterious Water Black Qi rolled in.

This Mysterious Water Black Qi was the origin of water, much more formidable than weak water. Within a single drop of this water lay the power of time and space. That meant, if a trace of Mysterious Water Black Qi was extracted, condensed into a drop, and taken outside, it could potentially evolve into a celestial grotto, a cave dwelling of an ancient immortal!

As this Mysterious Water Black Qi surged into Fang Han's life-bound world as if it were free, immediate transformations occurred once again. Fang Han's entire spirit became closely united with the Sea Eye. His spiritual world expanded boundlessly, and he saw a giant eyeball ceaselessly flashing at the bottom of the vast, boundless sea. It felt as if he was inside the eyeball, sharing an intimately inseparable connection with it.

This was exactly the result he desired.

Devour the Immortal Tea Tree, establish a close connection with the Sea Eye, and then collect the entire Sea Eye.

However, although he had established a close connection with the Sea Eye, with a slight movement, he felt that the entire Sea Eye was utterly impossible to be collected. Thinking about it, if every trace of Mysterious Water Black Qi was stimulated to evolve into a celestial grotto, how powerful of a spatial force would the entire Sea Eye contain?

With his current cultivation, he could not possibly accomplish it.

"The power of this Sea Eye is so heavy; trying to collect it is like a dragonfly trying to shake a stone pillar, absolutely impossible. Still, being able to establish a close connection with the Sea Eye means I am halfway to succeeding in stripping away the foundation of Ten Thousand Returns Immortal Island. I have gained immense benefits."

Although he could not collect the Sea Eye, Fang Han's entirety closely integrated with it. With just a slight thought, countless streams of Mysterious Water Black Qi rolled over within the Sea Eye, giving the body of the Primordial Ancestral Dragon an aura even closer to the origin of the sea than the Sea Emperor itself.

"The Boundless Great Sea!"

The Sea Emperor descended into the Sea Eye, seeing a dragon claw grabbing toward it, a smile of contempt emerging on its face, perfectly exhibiting a posture of overestimating one's abilities, just like a fierce tiger looking at a little white rabbit. The Sea Emperor spat four words from its mouth, dispersing a burst of power. Immediately, the Sea Eye seemed infected the aura, and the Mysterious Water Black Qi within actually stopped circulating.

"Slay Dragon!"

Swish!

The Sea Emperor stepped forward and cleaved down the Sword of the Sage in its hand. Before the sword arrived, sword momentum had already fully enveloped all of Fang Han's body. Stimulated by the sword energy, every single scale vibrated entirely, some shivering uncontrollably.

"What sword is this?"

Fang Han immediately retracted his dragon claw, his body twisting. The long body of the Primordial Ancestral Dragon swam through the Sea Eye, evading the sword momentum. He could already sense that although the phantom of the holy sword in the Sea Emperor's hands was merely an illusion, its power was extremely formidable, not inferior even to the phantom of the Spear of Vengeance unleashed by Xuan Wugu.

Taking a hit from the phantom of this sword, the body would be damaged, vital essence greatly injured, making it difficult to recover.

"Fang Han, you must be careful. This is the phantom of a King Grade Immortal Artifact of the Immortal Realm. Once injured, laws will break, and the soul may even be seized," Yan hurriedly said.

"Last time the Spear of Vengeance was also a King Grade Immortal Artifact. I only know that Spirit Artifacts, Treasure Artifacts, and Dao Artifacts are divided into Low Grade, Mid Grade, High Grade, and Peerless Grade. Are Immortal Artifacts different from them?" Fang Han asked suddenly; he truly was not very clear about the rankings of Immortal Artifacts.

"Immortal Artifacts are divided into many grades. Above Peerless Grade Immortal Artifacts, they are further divided into King Grade and Sovereign Grade. Any existence reaching King Grade Immortal Artifact status claims itself as a mighty figure, untamed by any existence, its power radiating across countless times and spaces, countless worlds, and countless alternate dimensions. Then, as long as any living being in any alternate dimension grasps the method to communicate with this King Grade Immortal Artifact, they can borrow its power through the method of sacrifice," Yan said.

"Such a mighty figure, setting up altars! Intent radiating out into countless voids, knowing that even the mighty figures of the Immortal Realm cannot transmit their power down into the lower realms. A King Grade Immortal Artifact can actually do this?" Fang Han felt shocked in his heart. His body twisted once more as he executed the Nine Transformations of the Dragon Form recorded in the Heavenly Dragon Secret Manual, showing its head without showing its tail, narrowly dodging the Sea Emperor's fatal slash.

Suddenly, the Sea Emperor altered its swordsmanship. The phantom of the "Sword of the Lost" in its hands rippled layer after layer of sword energy, unexpectedly executing a majestic yet murderous set of swordsmanship, scraping toward Fang Han.

"Lowly existence, though you have transformed into the phantom of the Primordial Ancestral Dragon, you cannot stop my Sword of the Lost. To dare defy the dignity of a wisp of this emperor's true spirit, you are unforgivable. However, I will let you witness the killing path of thirty-six moves of the Heavenly King Slaughtering Dragon sword technique, an unsurpassed art of the Heaven Realm."

Amidst the vibrations of the sword's momentum, the Sea Emperor unexpectedly let out a clear voice. This voice possessed supreme authority and oppressiveness. Its swordsmanship was actually an Immortal Spell, yet there were clearly no signs of magical power operating within its body.

Heavenly King Slaughtering Dragon Sword Art.

It was precisely targeted at Fang Han's Primordial Ancestral Dragon body. As the sword momentum unfolded completely, the extended form of the Primordial Ancestral Dragon was suddenly unable to absorb the Eight Divisions True Dragon Qi in the air; the passage to the Dragon Realm had actually been entirely blocked off. While this set of sword moves was completely laid out, sword light lingered everywhere like gossamer. Countless sword energies sought the gaps between the dragon scales, drilling in to destroy the anatomical structure of the Primordial Ancestral Dragon, attempting to disintegrate Fang Han's body.

Fortunately, Fang Han's Eight Divisions Pagoda had merged with the Tower of Myriad Deities. Otherwise, perhaps beneath the barrage of this Heavenly King Slaughtering Dragon Sword, the Eight Divisions Pagoda would have disintegrated, and the restrictive spells inside would have been destroyed.

"This Sea Emperor is so fierce!" The movements of Fang Han's Primordial Ancestral Dragon body turned unagile. With a shift of his divine will, he sent out several talismans to circle around him. These talismans, forged by the essence qi of Void Immortal experts and True Immortal experts, were activated up into the air, manifesting the phantoms of several powerful Void Immortals and True Immortals. However, the Sea Emperor paid no heed, merely giving a cold sneer and casually making a tearing motion with the longsword in its hand, shattering all talismans down to ashes.

It actually occupied an overwhelmingly dominant advantage!

No magical artifact could contend with the killing strike of the phantom of the "Sword of the Lost." Even the Cangsheng Great Seal and the Map of Yellow Springs would endure an unrecoverable damage to the true spirits within if they took a hit.

Rip!

Under the Sea Emperor's close pressing string of attacks, a strike from the sword astonishingly pierced the reverse scale of the Primordial Ancestral Dragon.

Fang Han immediately released an angry roar. His entire body transformed, unexpectedly detaching from the state of man and artifact unity. The Eight Divisions Pagoda took flight, picked right out of his body by a cut of the Sea Emperor's sword.

"Lowly existence, submit and be executed under this sword!" The Sea Emperor fiercely stepped forward. The longsword in its hand sparked a profound trajectory in mid-air, sealing off all of Fang Han's offensive routes, stabbing right at Fang Han's body.

With this sword thrust, the Sea Emperor had calculated that Fang Han had no way to escape, and no room to dodge. A smile emerged on its face.

Suddenly, Fang Han widely opened his own world, inconceivably planning to absorb the sword energy inside in an attempt to dissolve the sword energy utilizing the power of a world.

"Lowly existence. A measly small world, is it capable of neutralizing the will of the Sword of the Lost? Perfect, I'll shatter the laws of your world right now and have you suffer a crushing defeat!" The Sea Emperor's will surged like tides, driving the sword energy like divine light piercing through the universe directly into the depths of Fang Han's world. Going forward without returning, it did not need to be wary of any obstruction. Any existence daring to block the sword energy was torn asunder.

"What a powerful world! The fact that a lowly existence like you could possess such a formidable world indeed leaves me astonished. Still, it cannot withstand the slaughter of the Sword of the Lost." As the Sea Emperor thrust its sword into Fang Han's world, it was surprised at heart upon sensing the resistance the sword energy encountered. Consequently, it could not help but increase its power.

Instantly, Fang Han's predicament became exceedingly critical. With such a hazardous thing as the Sword of the Lost entering his inner world, it would undoubtedly inflict massive destruction.

However, an extremely eerie smile appeared on Fang Han's face, as if a conspiracy had succeeded.

Deep within his world, a massive entity abruptly took flight.

"Xuan Wugu, you've been sealed inside my world, being lonely for far too long. Help me withstand the power of the Sword of the Lost!" Boom, He opened the seal on Xuan Wugu's body.
