"Speaking of that second child of the Xiao family, he's quite peculiar!"

Seeing this Beast Spirit Banner, Yun Xiao couldn't help but recall the image of that genius of the Xiao family in his mind, and he also thought of the bidding scenario with Xiao Qiming at the auction.

"Judging by his appearance, could it be that he knows the secret of the Wuyan Cloth, or... does he also have a fragment of the Wuyan Cloth in his hand?"

Yun Xiao's conjecture was already very close to the truth. At the same time, he also felt some regret in his heart. If he had guessed these things earlier, perhaps he could have stopped Xiao Qiming outside the North Gate of Bianlei City, if not, at least taken away his Waist Storage.

However, now that things have come to this, Yun Xiao didn't dwell too much on it. After all, he already knew the clue of the third fragment of the Wuyan Cloth. He could slow down his pursuit later. Besides, after losing such face, the genius of the Xiao family would probably not let him go easily.

"The Beast Spirit Banner, it's really been a long time!"

Yun Xiao composed himself, holding the Beast Spirit Banner in his hand, recalling the Beast Spirit Banner he had seen in the Nine-layered Dragon Cloud in his previous life, it really felt like a lifetime ago.

To be honest, something like a Beast Spirit Banner goes against the order of the heavens. In the Nine-layered Dragon Cloud, it was already rarely seen. Only those wicked beings would secretly refine Beast Spirit Banners to kill Vein Demons and obtain their souls to enhance their own.

Yun Xiao didn't know that such a thing as a Beast Spirit Banner could be auctioned openly on the Tenglong Continent, but compared to ordinary people, he had a deeper understanding of the Beast Spirit Banner.

The Beast Spirit Banner also has grades. For example, the Beast Spirit Banner Yun Xiao had won at auction had already reached the Eighth Rank Middle Stage, which means the Vein Demons it could capture had also reached the Eighth Rank Middle Stage.

Since the Beast Spirit Banner possesses such formidable strength, during its refining process, it must have had a soul of at least Earth Rank Middle Level infused into it. Otherwise, it wouldn't be able to affect Vein Demons of Eighth Rank Middle Stage.

But this Power of Soul that enhances the Beast Spirit Banner, when obtained by ordinary people, cannot be separated out. They can only use the Beast Spirit Banner to hunt Vein Demons, collecting countless Vein Demon souls to enhance their own.

However, Yun Xiao possessed the memories of the Long Xiao Battle God from his previous life. With his disposition, he naturally wouldn't use the Beast Spirit Banner to hunt Vein Demons for souls, as that would be too against the order of the heavens.

Thus, Yun Xiao had a deeper purpose in acquiring the Beast Spirit Banner, which was to separate that Earth Rank Middle Level Soul from within it and make it his own.

"I wonder if this Power of Soul can allow me to directly break through to Earth Rank Middle Level?"

Such a fiery thought crossed Yun Xiao's mind. This was his real reason for obtaining the Beast Spirit Banner. Perhaps this separation and refining process would bring him a great surprise.

Whoosh!

With a wave of Yun Xiao's right hand, the Beast Spirit Banner spread flat on the ground in front of him, an invisible force spreading out, causing some Vein Demons in the lake to dive deeper, perhaps sensing the terror of the Beast Spirit Banner.

This was a Beast Spirit Banner that could capture Eighth Rank Middle Stage Vein Demon souls, and the way of the soul was never something Vein Demons were adept at. One careless move and their soul being absorbed would leave them as mere shells.

Huff... Huff...

Yun Xiao's hands formed a peculiar seal, and then from his brow, a majestic soul emerged, precisely his Earth Rank Low Level Soul Power.

The reason Yun Xiao dared to use his Earth Rank Low Level Soul Power to separate the Earth Rank Middle Level Soul of the Beast Spirit Banner was firstly because the latter was ownerless and without support, and secondly, because his Earth Rank Low Level Soul Power was far superior to that of ordinary Meridian Refining Masters.

The Meridian Qi cultivated through the Ancient Dragon Taming Technique was exceptionally refined. This Soul Power was far beyond what the same level of Meridian Refining Masters could compare and was even more formidable than the Long Xiao Battle God of his previous life at the same level.

The special aspects of this magical cultivation technique, Yun Xiao might have only explored less than half, but the benefits it brought him were unparalleled.

"Yin and Yang as realms, Sun and Moon converge, separate!"

As Yun Xiao's hand seal changed to an extreme, his mouth suddenly uttered a deep voice, similar to some sort of spell, and immediately his Soul Power forcefully collided with the Beast Spirit Banner.

Bang!

However, just as Yun Xiao's Soul Power came into contact with the Beast Spirit Banner, this multicolored flag moved without wind, erupting with an extremely formidable invisible force, as if resisting.

"Humph, you ancient soul, long dead, still dare to resist?"

Seeing this, Yun Xiao let out another low growl, the Soul Power in his mind continued to surge out, while under the operation of the Ancient Dragon Taming Technique, his Soul Power seemed to generate suction, causing the soul within the Beast Spirit Banner to struggle even more forcefully.

According to Yun Xiao's guess, the person who originally refined this Beast Spirit Banner likely wielded Soul Power of at least Earth Rank Middle Level, possibly even being an Earth Rank Advanced Meridian Refining Master.

If this Meridian Refining Master were still alive, it would be absolutely impossible for the Beast Spirit Banner to be put up for auction. The most likely possibility is that this Meridian Refining Master has already perished, and their belongings have somehow ended up in the hands of the Spirit Fighting Commerce branch in Bianlei City, allowing me to luckily acquire it.

Since that is the case, the Soul Power within this Beast Spirit Banner is but an ownerless residual soul. After being provoked by Yun Xiao's Soul Power, it made this final struggle, which in fact poses no significant threat to Yun Xiao.

"Disperse!"

About an hour later, Yun Xiao's expression suddenly turned serious. As the seals in his hand shifted, the Soul Power in his mind expanded again, eventually enveloping all the Soul Power within the Beast Spirit Banner.

Plop!

Without the support of Soul Power, the five-colored Beast Spirit Banner dropped powerlessly to the ground, as if it had lost its soul, its colors becoming somewhat dimmer.

It can be said that the Beast Spirit Banner, stripped of its Soul Power, truly became an ordinary flag at this moment, losing its miraculous effect of capturing the souls of Vein Demons.

This was another reason Yun Xiao obtained the Beast Spirit Banner, having witnessed too many tragic cases involving Vein Demons because of such banners in his past life.

Vein Demons aren't Strange Spirits; as long as humans don't provoke them, they usually don't seek trouble with humans lightly. Sometimes, they might even join forces to combat Strange Spirits.

Therefore, Yun Xiao's act of stripping away the Earth Rank Middle Level Soul Power from the Beast Spirit Banner can be seen as resolving a threat for some Vein Demons on the Tenglong Continent. Of course, these Vein Demons are unaware of this.

"Huh?"

Just then, as Yun Xiao's Soul Power enveloped the Earth Rank Middle Level soul within the Beast Spirit Banner and returned to his mind, he suddenly discovered that the enshrouded soul was frantically struggling, as if it suddenly gained its own Spiritual Wisdom.

"Still so reluctant?"

Yun Xiao was naturally prepared for such a situation, as it was the final struggle of the Beast Spirit Banner's soul, or rather, the soul of the one who had refined the banner, trying to seize a last chance at survival.

Of course, if this struggle were to succeed, Yun Xiao might not only fail to refine the Earth Rank Middle Level soul but could also be possessed by the soul of the dead owner, becoming a different person.

If it were a typical Earth Rank Low Level Meridian Refining Master, it would be uncertain if the Beast Spirit Banner's soul would successfully possess them. But unfortunately for it, this time it encountered Yun Xiao, whose Soul Power and understanding of the soul far surpassed the banner's original owner.

"Cease this futile struggle!"

Such a deep voice issued from Yun Xiao's throat, and as his Ancient Dragon Taming Technique operated, an intensely powerful Devouring Power erupted from his soul, immediately suppressing that strand of struggle.

Under the force of this mysterious cultivation technique, any struggle was futile. Perhaps only at this moment did Yun Xiao truly resolve the problem of the Beast Spirit Banner's soul, allowing him to begin refining without any worries.

Huff... Huff...

The Beast Spirit Banner's soul, enveloped by Yun Xiao's Soul Power, was now powerless to resist. As the Ancient Dragon Taming Technique operated, it was devoured and refined bit by bit, eventually transforming into nutrients that enhanced Yun Xiao's Soul Power.

Three more days quickly passed!

During these three days, no unexpected events occurred, whether at the periphery of the Big Lake or among the powerful Vein Demons within the lake, as if all had fallen into a strange calm.

Boom!

However, just when the third day dawned, an immensely powerful invisible force exploded from Yun Xiao's body, followed closely by his eyes, closed for three days, suddenly opening.

When Yun Xiao opened his eyes, they seemed to grow deeper like the boundless sea, subtly indicating a qualitative leap in his Soul Power.

"Earth Rank Middle Level soul, not bad!"

The returning Yun Xiao touched his brow, sensing that his soul had become more than twice as strong as three days ago, and couldn't help but smile with satisfaction. The refining over the past three days ultimately wasn't in vain.

"Now that Soul Power has broken through to Earth Rank Middle Level, it's time to try refining that Earth Rank Middle Level Elixir!"

Yun Xiao raised his eyes, glancing at a small fiery red silhouette in the distance. During these three days, Chi Yan had been on guard at the lake's shore, one reason Yun Xiao was able to refine without worry.

Now that his Meridian Refining Technique has improved, it's time to consider Chi Yan. After all, with Chi Yan's strengthened strength, he'll have more powerful combat capabilities, providing more assurance of safety in future endeavors.
