Some Immortal Palaces seem to be from the Nine Netherworld, with faint echoes of ten thousand ghosts roaring inside, exuding a sinister and terrifying aura.

At the same time, each of the six Immortal Palaces contains thick Yin Yang Qi, with waves of Yin Yang Qi shuttling back and forth within these six Immortal Palaces.

Xiang Ziyu’s entire aura kept rising, causing waves of terrifying energy to surge outward, making the surrounding air whirl madly, forming a massive vortex centered on him.

The next moment, Xiang Ziyu raised his hand and slapped towards the seawater in front of him.

This palm was purely condensed from Yin Yang Qi, embodying all his understanding and comprehension of Yin Yang Qi!

Though this palm wasn’t a spell and employed no treasures, its power was boundless.

Behind him, everyone felt the terrifying aura of this palm, and shock filled their hearts.

Immortal Lord Yun Huo continuously shook his head, thinking it was too terrifying. This should be the first time the opponent displayed all their power in front of them after encountering them.

Even though she possessed seven Immortal Palaces, just seeing this palm made her realize that if she fought to the death with the opponent, she would definitely be the one to die!

She even doubted how a cultivator with only six Immortal Palaces could unleash such a terrifying palm.

"Look at that Immortal Mountain!"

Suddenly, Immortal Lord Fu Liu among them shouted at the towering Immortal Mountain in front: "An Immortal Mountain measuring 8,600 feet!"

"In our Human Clan’s True Immortal Realm, very few have such a height in their Immortal Mountain!"

"Cultivators with an 8,600-foot Immortal Mountain seem to be disciples under Sect Leader Cao from the Hundred Peaks Sect."

"Xiang Ziyu! This person must be Xiang Ziyu!"

Everyone’s gaze fell on Linghu Gudu, who they had suspected before might be Xiang Ziyu, the ancient foremost Yin Yang Immortal King.

However, the proficiency in Yin Yang Qi that this person revealed was so terrifying that it surpassed even the Peak True Immortals, so they believed it couldn’t be Xiang Ziyu.

But now, with the appearance of this Immortal Mountain, it was almost certain that this person was Xiang Ziyu from Four Treasures Peak.

Linghu Gudu met their gaze and nodded lightly, acknowledging: "Indeed, he is my third senior brother."

As his words settled, everyone recalled the situations along the way, realizing why Linghu Gudu seemed to support and trust every decision made by the ancient foremost Yin Yang Immortal King.

It turns out he truly is his senior brother!

The Double Extremes Immortal Lord listened to the others’ words, feeling as if waves were crashing within his heart. How could someone who understood Yin Yang Qi far beyond him be a disciple of the Hundred Peaks Sect Leader, having fewer Immortal Palaces than him?

Though he wasn’t as proficient as the other in understanding the Way of Yin and Yang, his Immortal Palaces were more numerous, indicating only one scenario: the path that the other took was too vast, so vast that despite the high comprehension of Yin Yang Qi, only six Immortal Palaces were condensed!

In awe, Xiang Ziyu’s palm had already landed on the sea.

Instantly, the swords inserted upside down in the sea swayed madly.

The sharp swords did not fly out from the sea surface, yet Sword Qi shot out crazily from them. Each piece of Sword Qi contained either Yin Breath or Yang Breath; some Sword Qi contained both.

These streams of Sword Qi gathered above the seawater, eventually forming a Yin Yang Sword, half black and half white, with a faint figure emerging behind the sword’s phantom, seemingly Immortal Lord Yin Yang. He wielded the Yin Yang Sword and stabbed forward.

The seemingly understated sword strike, however, caused the seawater below to roar madly after it struck, with massive waves rising to the sky. The Endless Sea instantly erupted into a terrifying tsunami, so powerful it made the surrounding void and distant land shake crazily.

Everyone felt they were far enough from the sea, yet at this moment, their bodies uncontrollably swayed.

One sword strike startled the heavens, and changed the color of the void.

As soon as this sword appeared, a sun and moon simultaneously emerged in the void, seeming to rise from the sea horizon together, with pure breaths gushing out from them.

The sun symbolized Yang; the moon symbolized Yin. 𝙧𝙚𝙚𝔀𝒆𝓫𝓷𝙤𝓿𝒆𝙡.𝒄𝙤𝓶

Yin Yang Qi!

The Yin Yang Qi within this sun and moon perfectly fused with the Yin Yang Qi of this space.

Subsequently, the Yin Yang Qi in the entire world, even the entire relic, seemed to pour into this sword in an instant.

Evidently just one sword, even merely a sword condensed from Sword Qi, but as it fell, it felt like it aggregated all things in heaven and earth, gathering the breath of everything!

This sword even gave everyone the illusion of splitting heaven and earth with a single strike.

With heaven and earth being divided, not to mention the seawater and air!

The Endless Sea was torn apart, and the frightening Sword Qi pierced forward, seemingly capable of destroying everything around.
