Half a month passed quickly!

Within the Thunder King Main Hall, even Yun Xiao did not expect that this time of refining would take such a long time. However, at this moment, he had no mind to think about the issue of time because he had already reached an extremely critical juncture.

After half a month of refining, the Thunder King's Heart, which was originally the size of a human head, was now only a thumb-sized mass, while the rest of the energy was gradually absorbed by Yun Xiao, becoming nourishment for his power enhancement.

It's worth mentioning that at this moment, not only was Yun Xiao's Meridian Qi cultivation at the cusp of breaking through the Qi Seeking Realm Late Stage, but even his physical strength had been elevated to another level due to the tempering of this Thunder Heart.

Apart from the Meridian Qi cultivation and physical strength, Yun Xiao had a third joy, which was the power of the soul. At this time, his power of the soul had astonishingly reached the Earth Rank Low Level, a substantive sublimation.

The breakthrough in the power of the soul made Yun Xiao's mind clearer and more capable of controlling the rampant power of thunder and lightning. This was also the main reason he could persevere for half a month.

Achieving the Earth Rank Low Level soul made Yun Xiao's Meridian Refining Technique directly break through to the Earth Rank Low Level Meridian Refining Master level, providing him another powerful means, which would make him more revered when traversing the Tenglong Continent.

It was precisely this so-called three-pronged approach that allowed Yun Xiao to persist for half a month; if it were only a single enhancement of Meridian Qi or physical strength, he might have long since exploded and died.

After all, this was the Thunder King's Heart left by a Heavenly Rank expert, and although its power was much smaller than that of the Thunder King, if an ordinary cultivator at the Qi Seeking Realm Late Stage dared to forcibly refine it, the final outcome would be extremely tragic.

Moreover, this time, the Golden Snake Worm and Red Feather did not come to fight with Yun Xiao for the energy, which allowed him to absorb more Thunder King's Heart energy, but also increased the risk of failure.

Fortunately, Yun Xiao had endured most of the time. Now, he only needed to endure this final critical moment to achieve great success, though the Meridian Qi cultivation at the edge of breakthrough undoubtedly left him somewhat torn.

Bang!

At a certain moment, a thunderous cracking sound suddenly came from within Yun Xiao's body, and then the last thumb-sized mass of the Thunder King's Heart suddenly exploded, causing his body to stiffen abruptly.

Countless thunders, like silver snakes and worms, scoured his flesh and blood and meridians thoroughly, merging with the external thunder, attacking from both inside and outside.

Yun Xiao, who had already adapted to external thunder, couldn't help but grunt due to such a sudden heavy blow, but fortunately, under the operation of the Ancient Dragon Taming Technique, the internal thunder power did not cause him any lethal harm.

Especially after Yun Xiao survived this first impact, he suddenly discovered that all his meridians seemed to emit a faint silver electric light, appearing extremely mystical.

Bang!

When a strange thought flashed in Yun Xiao's mind, these silver thunders finally became the last straw that helped him break through, a majestic aura soared into the sky, and at the moment when Yun Xiao opened his eyes, it seemed as if two bolts of lightning shot out from his eyes simultaneously.

Qi Seeking Realm Peak!

It was evident that at this moment, Yun Xiao truly broke through to the Qi Seeking Realm Peak. With this breakthrough, it confirmed that his decision to come to Thunder King Valley was not wrong.

In fact, from the time Yun Xiao left Hidden Dragon Continent to explore the Boundary Tower and then arrived at Tenglong Continent, it was only about half a year in total, yet in this short half year, he astonishingly advanced from the Qi Seeking Realm Early Stage to the Qi Seeking Realm Peak.

This almost spans a whole Great Rank, and Yun Xiao completed it in just half a year. If the cultivators outside knew this, they might have their eyeballs pop out directly.

Ordinary people require at least several years or even over a decade to break through a small realm in the Qi Seeking Realm, and even geniuses like Ye Suxin and Tong Baisha of the Killing Heart Sect took over a year at the beginning.

The Ancient Dragon Taming Technique, if cultivated according to routine, might take even longer than ordinary cultivators because it needs Yun Xiao's cultivated power to become more substantial.

It's like a piece of ordinary iron needing to go through numerous pounding to become a piece of divine iron, forcing out the impurities from within continually, only then can it become an unparalleled treasure.

The Ancient Dragon Taming Technique, for Yun Xiao, is undoubtedly that process of countless pounding, only in this way can it ensure that Yun Xiao, when breaking through to a higher Great Rank in the future, doesn't fail due to the vacuity of Meridian Qi.

It must be said that Yun Xiao's recent breakthroughs were not through routine cultivation, whether it was the Seventh Rank Advanced Thunder Spirit Crystal, the Earth Rank Middle Level Thunder Wood, or this Thunder King's Heart left by a Heavenly Rank expert, all were key to Yun Xiao's consecutive breakthroughs.

However, under the refining of the Ancient Dragon Taming Technique, the energy of these Heavenly Materials and Earthly Treasures, once absorbed by Yun Xiao, became extremely substantial, without the aftereffects ordinary cultivators experience when breaking through realms using elixirs or Heavenly Materials and Earthly Treasures.

This is why Yun Xiao only broke through to Qi Seeking Realm Peak after refining the Heavenly Rank Thunder King's Heart, otherwise, such a Thunder King's Heart could possibly have allowed him to break through to the Origin Seeking Realm Early Stage directly.

After completing the breakthrough, Yun Xiao quickly understood these potential details. He was well aware of the principle that a meal must be eaten one bite at a time; only with a solid foundation could one strive for higher realms in the future.

"Peak of the Qi Seeking Realm!"

Yun Xiao opened his eyes and exhaled a breath of foul air. Even in that breath, a hint of thunder attribute was seemingly contained. Feeling the majestic Meridian Qi surging through his body, he couldn't help but feel quite satisfied.

"The meridian qi cultivation at the peak of the Qi Seeking Realm is comparable to the physical strength of an eighth rank low-level pulse demon, as well as the soul power of an Earth Rank low-level!"

Yun Xiao stood up, muttering softly, counting the gains from entering Thunder King Valley this time. The dazzling brilliance in his eyes grew more intense because, for him, it was simply a leap in strength.

"Oh yes, the Thunder Attribute Ancestral Veins!"

After feeling these most direct elements, Yun Xiao's mind suddenly shifted. A slight intention formed under his shoulders on his back, as if he wanted to discover an even greater surprise.

"Thunder Wings, appear!"

With a low shout from Yun Xiao, a silver light flickered under his shoulders, followed by a soft pop. On both sides, silvery thunder was aligned in a certain way, finally forming a pair of over-ten-foot-long Silver Light Electric Wings.

Flap! Flap! Flap!

As Yun Xiao willed it, the Thunder Wings gently flapped. Then, with the sound of whistling wind, his entire figure rose from the ground, surprising and delighting him at the same time.

Whoosh!

With the fluttering of the Thunder Wings, Yun Xiao's entire body swiftly soared into the air, making a few loops in the sky above the Thunder King Main Hall. Unlike previous times when he used the Thunder Wings, there was now no longer any sense of being powerless.

"Tsk-tsk, it's really unexpected that you, kid, would preliminarily grasp these Thunder Dragon Wings at the Qi Seeking Realm. It's simply... simply..."

While Yun Xiao was happily familiarizing himself with the flying power, a voice of wonder sounded from within his body. There was no need to think twice; it was undoubtedly from the Golden Snake Worm Xiao Wu. But towards the end, he seemed unsure how to put it into words.

"Thunder Dragon's Wings?"

Upon hearing this somewhat unfamiliar name again, Yun Xiao's heart skipped a beat as he thought of something and asked aloud, "Could it be that my Thunder Wings have some connection with the legendary Thunder Dragon?"

The Nine Dragons Continent anciently had Nine Dragons, and Yun Xiao, the reincarnation of the Long Xiao Battle God, was somewhat clearer about them. Among them, the Five-Clawed Golden Dragon was one kind, and the Thunder Dragon was also one.

It is said that the Thunder Dragon is an embodiment of heavenly thunder, possessing the immeasurable power of Thunder Punishment. The thunder power spewed from its dragon mouth could reduce even some experts of the Holy Rank Third Realm to ash in an instant, not much inferior to the Heavenly Tribulation of the Heavenly Dao.

Yun Xiao perhaps never imagined that he could be connected with the Thunder Dragon in this lifetime. However, when he thought of his Ancient Dragon Taming Technique and the self-proclaimed Five-Clawed Golden Dragon Xiao Wu, he became much calmer.

Many things that have happened in this life since his rebirth, even with the previous life's knowledge as the Long Xiao Battle God, were quite incomprehensible, especially that mystical Blood Moon Jade, which had brought Yun Xiao countless puzzling aspects.

"Nonsense, if not for these Thunder Dragon Wings, would you, kid, have flying power at the Qi Seeking Realm?"

Upon hearing Yun Xiao's question, the Golden Snake Worm Xiao Wu mockingly retorted, though he still didn't answer Yun Xiao's question; or perhaps he too didn't know how to answer.

But as Golden Snake Worm said, a cultivator capable of flight at the Qi Seeking Realm is extremely rare, likely only Yun Xiao. Other cultivators wanting to fly either strive to break through to the Heavenly Rank Third Realm or rely on a flying beast pulse demon—none of them as carefree as he was at the moment.

"Heh heh, now that my strength has greatly increased, it's time to leave. I wonder if my old friends are still waiting for me outside?"

Since he couldn't figure it out, Yun Xiao simply stopped thinking about it. He clenched his fist, taking one last glance at the Thunder King Main Hall, and with a light chuckle, vanished within the Thunder King Main Hall.

It must be said that Yun Xiao's speed had significantly increased after refining the Thunder King's Heart. Yet, when he appeared outside the Thunder King Main Hall, he found not a soul in sight.

"Have they all left? That's not like those folks!"

Seeing this, Yun Xiao was puzzled. From what he knew of those cultivators, they wouldn't have given up on the treasures in the Thunder King Main Hall until the last minute, especially not Tong Baisha of the Killing Heart Sect. Before entering the Thunder King Main Hall, there had even been some unpleasant conflicts with them.
