The Land of Eight Extremes, an Innate Spirit Treasure

Above the East Sea, two streaks of light swiftly swept in from the horizon, flying southeast.

The owners of those two escaping lights were Lei Xiao and Yun Xiao. As for Qiong Xiao and Bi Xiao, they had returned to Three Immortal Isles to refine their Innate Spirit Treasures.

"Lei Xiao, Third Sister was only joking. Innate Spirit Treasures can only be encountered by chance, never sought. It would be perfectly normal if we failed to find one," Yun Xiao said softly, worried that he might feel pressured.

At her words, the corners of Lei Xiao's lips rose in a confident smile. "Rest assured, Eldest Sister. I will definitely help you find an Innate Spirit Treasure."

As a transmigrator from the future, Lei Xiao still knew the locations of some Innate Spirit Treasures that remained ownerless in this era.

The Eight Extremes of the Primordial World corresponded to the origins of heaven and earth in all eight directions, nurturing eight Innate Spirit Treasures. At present, none of those eight treasures had yet emerged into the world.

Among them, the southeastern Wind Abyss—the Xun position—was located in the East Sea. It was also Lei Xiao's destination on this journey.

Yun Xiao shook her head without speaking. Clearly, she did not believe that Lei Xiao could truly lead her to an Innate Spirit Treasure.

It was not that she looked down on Lei Xiao. Innate Spirit Treasures were simply too rare; even Zenith Heaven Golden Immortals found it difficult to trace their whereabouts.

As for Lei Xiao's previous discovery of an Innate Spirit Treasure with Bi Xiao, she considered it nothing more than pure luck.

"It does not matter if Eldest Sister does not believe me. You will know once we arrive," Lei Xiao said with a smile.

Yun Xiao glanced at him. Seeing how calm he looked, as though he was not spouting empty boasts, she sighed inwardly and said nothing more.

She had never been one for many words. Since Lei Xiao insisted on going, she would accompany him on the journey. As for whether they could find an Innate Spirit Treasure, she did not hold much hope.

The two continued deeper into the East Sea.

"Lei Xiao, your cultivation has already reached the peak of the Golden Immortal realm, but from what I can see within you, it seems you have yet to nurture the power of immortality," Yun Xiao suddenly said one day.

Lei Xiao was slightly startled, then nodded. "Eldest Sister's eyes are indeed keen. I have not yet condensed the power of immortality."

Golden Immortals were immortal.

Condensing the power of immortality was equivalent to forming a kind of "Dao Fruit" for a Golden Immortal.

Simply put, a Golden Immortal who had condensed the power of immortality possessed an endless lifespan. Even if all spiritual qi between heaven and earth completely vanished, they would not die naturally.

To condense the power of immortality, one had to achieve the Three Immortalities: an immortal body, an immortal Primordial Spirit, and an immortal origin. Lei Xiao had already met the requirements for the first two, but he had been unable to attain immortality of origin.

Lei Xiao vaguely sensed that this was related to the degree of fusion between the Purple Firmament Origin Divine Thunder and himself.

At present, the fusion between the Purple Firmament Origin Divine Thunder and him had barely reached one percent, far from sufficient for immortality of origin.

By his estimation, the fusion rate would need to reach at least three percent before it fulfilled the conditions for immortality of origin.

This was largely because Lei Xiao cultivated the Nine-Turn Primordial Essence Art, which had made his Primordial Spirit too powerful. Previously, one percent fusion had nearly been enough, but after his Primordial Spirit strengthened, his corresponding origin had also been elevated.

Still, this was not a bad thing.

The stronger his foundation, the stronger the power of immortality he would naturally condense.

As for accelerating the fusion between the Purple Firmament Origin Divine Thunder and his origin, Lei Xiao already had an idea.

"Do you need my help?" Yun Xiao asked.

"Eldest Sister can help me condense the power of immortality?" Lei Xiao looked at Yun Xiao curiously.

"...There is a method..."

Yun Xiao avoided Lei Xiao's gaze and paused before saying, "But it would be best not to use that method."

Lei Xiao: ???

Eldest Sister, you are only saying half of it, and with that hesitant expression and those slightly reddened ears, you have only made me more curious about the rest.

"Eldest Sister, what method is it exactly?" Seeing Yun Xiao's slightly evasive gaze, Lei Xiao became even more curious.

When Yun Xiao saw him press the matter, a rare blush appeared on her fair cheeks. She lightly bit her lower lip and said in an unnatural tone,

"If you truly help me find an Innate Spirit Treasure, I will tell you."

"Alright."

A confident smile appeared on Lei Xiao's face. He would learn this secret soon enough.

Time slowly passed, and in the blink of an eye, twenty-six years had gone by.

By now, Lei Xiao and Yun Xiao had reached the deepest reaches of the East Sea. Not even sunlight could reach this place. The surrounding waters were dark and unfathomable, with layer upon layer of dense clouds and astral winds blocking out the light of heaven. Only scattered ghostly blue phosphorescent flames drifted and sank upon the sea, reflecting the surging undercurrents.

The entire sea region was shrouded in dense astral winds. Their howls pierced the darkness as invisible wind blades sliced through space. In the densest areas, even space had been carved with tiny black fissures.

This place could be called a forbidden zone of life.

"Lei Xiao, are we really still going forward?"

Yun Xiao gazed at the terrifying innate astral winds ahead, which seemed capable of grinding everything to dust, her delicate brows knitting together.

Even with her cultivation, she could clearly sense the destructive power contained within them—a horrifying force sufficient to destroy both her body and Primordial Spirit.

"The Innate Spirit Treasure is ahead."

As he spoke, Lei Xiao willed it, and the Innate Fire Spirit Pearl flew out from within his body, hovering above his head.

The Innate Fire Spirit Pearl spun round and round, casting down curtains of crimson flame that blocked all the surrounding innate astral winds outside.

"Eldest Sister, stay close to me from here on. If any innate astral winds break through the Innate Fire Spirit Pearl's blockade, clear them out at once." Lei Xiao's expression was solemn.

They were still at the outskirts of Wind Abyss, yet the surrounding innate astral winds were already this powerful. One could imagine just how terrifying the astral winds near Wind Abyss's center would be.

He needed Yun Xiao's help.

"Alright. You must be careful as well. If it truly cannot be done, then give up. At worst, we can return when our cultivation is stronger in the future. Do not force yourself," Yun Xiao cautioned.

"Rest assured, Eldest Sister. I know my limits."

With that, Lei Xiao hesitated no longer. At a thought, the Innate Fire Spirit Pearl shone brilliantly, transforming into a crimson rainbow as it carried Yun Xiao headlong into the terrifying innate astral winds capable of shredding Primordial Unity Golden Immortals.

Rumble—

The instant they entered Wind Abyss, the deafening howl of raging winds poured into their ears like ten thousand galloping horses.

Countless blue-gray innate astral winds transformed into tangible blades, hacking madly at the crimson curtain of flame. Blinding sparks erupted alongside a teeth-grating screech of friction.

The curtain of flame shook violently, as though it could be torn apart by the endless astral winds at any moment.

The immortal power within Lei Xiao's body surged into the Innate Fire Spirit Pearl like floodwaters bursting through a breached dam, repairing the flame curtain that was on the verge of being ripped apart.

These innate astral winds were indeed tyrannical. Even an upper-grade Innate Spirit Treasure like the Innate Fire Spirit Pearl seemed somewhat strained before such might of heaven and earth.

From time to time, innate astral winds broke through the flame curtain's blockade. Fortunately, Yun Xiao reacted with equal speed. With a light lift of her jade-white hand, streams of condensed immortal light formed at her fingertips, precisely annihilating the invisible wind blades trying to slip through the gaps in the flame curtain.
