All around, the cultivators immediately panicked, hurriedly shouting: "This Dao Companion of the Human Clan, we didn’t speak, those wanting mutual destruction with you are other cultivators!"

"Yes, it’s that Demon Clan cultivator over there, and those two Evil Clan cultivators. Go find them!"

"No..."

In an instant, every cultivator in the Yin Yang River was dragged beneath the water. They wished for mutual destruction with their opponents, yet they fell to the bottom without even seeing the other’s shadow.

Finally, they understood why those previous cultivators died after falling into the water. The suction of the Yin Yang Qi below was terrifyingly powerful, coupled with a kind of rotation power, which invaded their bodies and rampaged crazily.

Within moments, all the alien race cultivators’ corpses floated to the surface.

After Xiang Ziyu collected the Heaven and Earth Rings from these alien races, he didn’t leave immediately but stayed to continue studying the Yin Yang Qi here. Only after understanding the characteristics of this Yin Yang Qi did he leave.

Subsequently, leading everyone onward.

This time, everyone was thoroughly convinced, and Xiang Ziyu, after seeing the danger ahead, also confirmed one thing—each stage of this relic is interconnected.

Aside from the first stage, to pass the second stage, one needs to understand the changes in Yin Yang Qi from the first stage, then during the third stage use the changes from the second stage, and the fourth stage employs the third stage’s changes.

And so, he led everyone forward.

Soon, a vast ocean appeared ahead of him!

The previous Yin Yang River he had crossed was not even a tenth of this ocean.

This ocean, half pitch black and half pure white, with an island in the center. Above the island, Yin Yang Qi converges, intertwining and slowly rotating.

Though the scope of the island didn’t look large, everyone viewing the island had an illusion that the endless Yin Yang Qi within the relic emerged from this island, from the Yin Yang Qi above the island.

Just by watching the Yin Yang Qi from afar, everyone felt as if the Yin Yang Qi was never-ending, a seemingly eternal illusion.

It was clearly just plain black and white, yet observing the two colors, people felt as though all colors of the world were contained within.

"This... this should be where the final inheritance lies."

"But to enter here... these swords, what a terrifying feeling!"

Looking at the ocean before them, countless sharp swords are plunged into it; some pitch black, some resembling white jade, and others intermingled with black and white, the swords with dual colors differing among them—some have equal black and white, some slightly more white or black, and some are almost completely black with just a trace of white!

At a glance, it’s impossible to count just how many Yin Yang sharp swords there are on this ocean.

These swords appear to be inserted chaotically, yet upon closer inspection, they seem to follow some kind of pattern, thrust into the ocean surface.

A terrifying pressure surges from each Yin Yang sword, and everyone feels their hearts pierced just by standing on the shore, watching these swords.

Despite previously guiding them through perilous places, seeing these Yin Yang swords this time stirred a deep unease within everyone.

They truly doubted whether Xiang Ziyu could break through the Sword Qi.

For a time, all eyes fell upon Xiang Ziyu.

Standing on the shore, Xiang Ziyu felt the aura emitted by the Yin Yang swords in the ocean, his face revealing a serious expression.

The Yin Yang Qi in these swords was incredibly special, seemingly gathering all variations of Yin Yang Qi here.

He stood on the shore, looking across, without moving.

Around him, everyone dared not disturb him.

Xiang Ziyu stood there for ten days.

After ten days, he turned to look at everyone and said: "You all back up a bit."

Around him, including Immortal Lord Dual Pole, everyone backed up, stopping only after retreating a hundred feet.

Yet Xiang Ziyu shook his head, saying: "Keep backing up—the further, the better."

As his words fell, an unexpected look immediately appeared on the faces of those around him, and Linghu Gudu asked: "Why back up so far? Dao Companion, have you found a way to break it?"

"No," Xiang Ziyu shook his head, "This should be the last trial, making it exceptionally different. I haven’t thought of a way to break it, so for now, I will test it, that’s why you must retreat further."

Upon hearing this, everyone turned solemn. The previous stages required little time to break, instantly done, yet this stage had held him for ten days without assurance.

Everyone stepped back to a safe area, as far as possible, stopping only when there was no room to retreat.

Behind the Immortal, an Immortal Mountain rose from the ground, and atop it, six mystical Immortal Palaces emerged, each resembling palaces of the Immortal Realm, filled with harmonious tunes and the Immortal Qi swirling at the palace’s periphery.
