Seeking Treasure in Tang Valley

Just as Lei Xiao and Bi Xiao were heading to Tang Valley, Yun Xiao emerged from seclusion on Three Immortal Isles.

"Eldest Sister, you've finally come out of seclusion. Third Sister and Fourth Brother have left Three Immortal Isles," Qiong Xiao said as she appeared.

"I know."

Yun Xiao nodded, with no trace of surprise in her eyes.

The control of Three Immortal Isles' innate grand formation was in her hands. In truth, she had known the instant Lei Xiao and Bi Xiao left. She simply did not know how to face Lei Xiao for the moment, so she had not shown herself.

Seeing Yun Xiao remain so composed, Qiong Xiao was somewhat surprised but did not dwell on it. She suggested, "Eldest Sister, now that you have emerged from seclusion, why don't we go look for Third Sister and Fourth Brother? Some time ago, I suddenly felt a palpitation in my heart. Perhaps Third Sister and Fourth Brother encountered danger."

The bond between the Three Xiao was extremely deep. The last time she had felt that palpitation, she had guessed it was most likely related to Bi Xiao.

"Third Sister did indeed encounter danger. However, she should have already resolved it and obtained a great fortuitous opportunity," Yun Xiao said.

"Eldest Sister, how do you know Third Sister obtained a great fortuitous opportunity?" Qiong Xiao asked doubtfully.

"Have you forgotten? The luck of us three sisters is connected. Not long ago, I sensed my own luck rise considerably out of nowhere. The two of us have both been cultivating in seclusion on Three Immortal Isles, so this sudden increase in luck must be related to Third Sister. It must have been caused by her obtaining a great fortuitous opportunity," Yun Xiao explained.

Upon hearing this, the last trace of worry in Qiong Xiao's heart instantly vanished.

"Eldest Sister, cultivating in seclusion is far too slow for improving our cultivation. Let's go out and seek opportunities as well!

"A great expert is giving a sermon on Purple Abode Island. Countless Golden Immortals and Great Unity Golden Immortals are gathering there. Let's go take a look too. Perhaps we'll run into Third Sister and Fourth Brother on Purple Abode Island."

At Qiong Xiao's words, a flicker of interest appeared in Yun Xiao's eyes.

Those who could be called great experts were all first-rate powerhouses of the Primordial World. Under normal circumstances, no great expert would waste their time preaching the Dao to a group of beings far weaker than themselves.

The Dao was not to be passed on lightly; it involved karma.

Thus, it was rare to hear of great experts preaching the Dao in the Primordial World, especially in such a widely publicized fashion that had drawn nearly all the "powerhouses" of the East Sea.

No matter what, this was a great fortuitous opportunity. Otherwise, it would not have attracted so many Golden Immortals and Great Unity Golden Immortals to hear the sermon.

"Alright."

After a brief hesitation, Yun Xiao nodded.

"Fourth Brother, are we still going forward? Up ahead is Tang Valley's core region. Solar True Fire exists there. With our cultivation, we'll probably turn to ashes if we so much as touch a trace of it."

At this moment, the ground beneath them was no longer seawater, but crimson lava.

Scalding molten rock surged and rolled like a viscous sea of blood. Whenever a bubble burst, it spewed a terrifying heat capable of instantly melting a Golden Immortal.

Ahead lay a sea of fire where the void itself had been completely warped by terrifying heat. Heavenly fire, earthly fire, and lightning fire intertwined, forming a Fire Region.

Ordinary heavenly fire, earthly fire, and lightning fire were manageable. With the top-grade innate spiritual treasure, the Dragon-Phoenix Flute, they could still withstand them.

However, aside from heavenly fire, earthly fire, and lightning fire, Solar True Fire would occasionally appear within the Fire Region. Even with the Dragon-Phoenix Flute, Bi Xiao had no confidence that she could resist it. After all, even Golden Immortals of the Great Luo realm had to retreat when faced with Solar True Fire.

"Third Sister, wait here for me. I'll walk the rest of the way alone," Lei Xiao said.

"Alone?"

"Fourth Brother, don't do anything foolish. Tang Valley's core is far too dangerous, and there might not even be an innate spiritual treasure there. Third Sister will accompany you to look elsewhere," Bi Xiao hurriedly urged.

"Before, I wasn't certain whether Tang Valley truly had an innate spiritual treasure. But now, I'm certain that one lies in its core."

As he spoke, Lei Xiao waved his hand, and a ball of crimson-gold flame appeared. It was the Phoenix Divine Fire origin he had obtained from the illusionary world.

Within the crimson-gold flames, a fire phoenix manifested. It let out a clear phoenix cry and spread its wings, eager to fly.

It seemed that something deep within the Fire Region was drawing it in.

"Third Sister, with this thing, I need not fear even Solar True Fire."

The Primordial World had three great origin divine fires: Solar Divine Fire, Southern Brightaway Fire, and Red Lotus Karmic Fire.

Solar True Fire was derived from Solar Divine Fire, while Phoenix Divine Fire was derived from Southern Brightaway Fire. The two belonged to the same level.

Lei Xiao flicked his fingertip, and the ball of crimson-gold flame turned into a streak of light that circled around him.

In an instant, an overbearing aura from the sovereign of all flames swept outward. The heavenly fire, earthly fire, and lightning fire that had originally been wildly violent immediately recoiled as though they had encountered a monarch, forcibly making way for a safe passage ahead of them.

Bi Xiao's beautiful eyes widened as she stared at the scene in utter disbelief.

Even if she used an innate spiritual treasure, she could only protect herself. She could not directly carve out a safe path through the Fire Region like Lei Xiao had.

"Fourth Brother, I should still come with you. There may be other dangers in this Fire Region. With me there, we can look after each other," Bi Xiao said.

After hesitating briefly, Lei Xiao nodded. "That works too."

He had not expected the Phoenix Divine Fire origin to be so effective, which was why he had asked Bi Xiao to stay behind.

With a thought, the Phoenix Divine Fire origin at his fingertips blazed brightly. The flames that had circled his body instantly spread outward, transforming into a massive crimson-gold barrier that firmly protected Bi Xiao within as well.

Then, Lei Xiao released his restraint on the fire phoenix.

"Screech—"

The fire phoenix spread its wings and shot toward the deepest part of the Fire Region like a crimson bolt of lightning tearing through darkness.

"Follow it!"

Lei Xiao shouted, and the crimson-gold barrier protecting them moved with him.

With Phoenix Divine Fire clearing the way, the heavenly fire, earthly fire, and lightning fire that had been prowling and roaring outside the barrier scattered to either side as if avoiding venomous serpents.

A quarter of an hour later, a gigantic fireball appeared before them. This enormous fireball was the source that had drawn the fire phoenix.

With a thought, Lei Xiao recalled the fire phoenix that had charged toward the enormous fireball.

"This is... the sun!"

Bi Xiao raised her head and stared at the gigantic fireball floating in the void like a miniature blazing sun, her beautiful eyes filled with shock.

"No... this isn't a real sun."

Lei Xiao's voice came from beside her, carrying a trace of barely restrained excitement. "This is an innate spiritual treasure."

Bi Xiao carefully examined the enormous fireball before her. Very soon, she caught sight of the innate indestructible spiritual light unique to innate spiritual treasures upon it.

"Fourth Brother, you're incredible. You really found an innate spiritual treasure! Quickly leave a primordial spirit imprint on it and refine it initially!" Bi Xiao's expression was excited, as though she herself had obtained the innate spiritual treasure.

Lei Xiao nodded at her words. His divine sense spread out and extended toward the enormous fireball.
