Doupo: His understanding is incredible, and he shocked Yao Lao at the beginning!

As wisps of gray haze slowly overflowed from the depths of the bone wings, the sky suddenly echoed with a shocking beast roar, which contained a violent and endless ferocity that was enough to shake the mountains and rivers, as if the ancient giant beast had revived and was about to split the sky.

This roar was like an invisible command, instantly giving life to the gray airflow, which surged towards Xiao Yan, covering the sky and the sun, with great momentum.

Facing this sudden change, Xiao Yan's eyes flashed with a trace of surprise, and then a faint smile appeared at the corner of his mouth.

He knew that in the face of unknown challenges, only by responding to changes with the same attitude can one remain invincible.

So, he moved his mind, and the majestic soul power in his body roared out like an awakened dragon, turning into a dazzling spiritual light column, resolutely meeting the surging, unknown gray airflow.

Gray air flowed out from between the bone wings, and it seemed to be given life in an instant, squirming and interweaving wildly. In just a moment, it condensed into a huge beast woven from gray haze.

The beast's body was hazy due to the thin air flow, and its outline was blurred. It was difficult to see its full appearance, but it added a bit of mystery and oppression.

On the top of its head, a red, blood-red, tyrannical light column suddenly appeared, like a pair of eyes burning with anger and madness, locking directly on Xiao Yan, releasing a heart-pounding pressure.

"Roar--!" With a deafening roar, the blurred beast body seemed to be injected with endless anger and power. Its momentum was like thunder and lightning, turning into a running gray rhino, as if carrying the momentum of destroying the world, fiercely facing Xiao Yan's soul power.

"Bang!" A loud noise shook the heart. The originally illusory energy confrontation was like the collision of metal and stone, with a full sense of substance, and a deafening roar broke out between the two.

At the collision point, the space seemed to be gently kneaded by an invisible hand, and circles of ripples visible to the naked eye spread rapidly, just like the lake surface was hit by a huge rock, rippling layers of ripples.

In this deafening collision, the fuzzy beast body condensed by the gray airflow also made a low and suppressed groan, as if it had endured a considerable impact.

However, this short silence did not make it retreat, but instead stimulated the rage and indomitable spirit deep in its heart.

Inside the beast body, the soul power surged again, like an undercurrent, gathering into a more majestic source of power, ready to meet the next round of fierce offensive, vowing to completely destroy the obstacles in front of it.

"So that's how it is. The Sky Demon Phoenix Clan really values ​​its remains, and there are indeed many mysteries behind it." Xiao Yan looked at the illusory demon beast, whose power was getting stronger and stronger. He couldn't help but curl up a playful smile at the corner of his mouth. Then, with a thought, the Super Falling Heart Flame suddenly burst out with unprecedented power, and the breath of heat and destruction instantly spread.

The release of this power was like a boulder thrown into a calm lake, instantly shattering the illusory beast form and stirring up the scattered gray airflow.

They were like encountering a natural enemy, terrified, fleeing everywhere, trying to escape from the destructive flames.

However, under Xiao Yan's precise control, the Super Falling Heart Flame was like a hunter with intelligence, keenly locking on every fleeing target, chasing them closely, and finally suddenly opening its huge mouth and swallowing them one by one.

After swallowing the gray airflow, the Falling Heart Flames did not stop, but returned with a full load, turning into streams of light, and re-integrating into Xiao Yan's soul body.

At this moment, Xiao Yan's heart was filled with indescribable ecstasy - he was surprised to find that his soul power had quietly increased slightly and significantly!

You know, it has always been extremely difficult to enhance soul power, even for him, his own cultivation was not particularly fast.

It was only with the Soul Palace, a transport and integration force, that he was able to break through to the Heavenly Rank.

Xiao Yan had long known the effect of gray airflow in enhancing the soul.

But the gray airflow could still enhance his soul at the Heavenly Rank, which really surprised Xiao Yan.

As for the cruelty and negative emotions hidden in the depths of the gray airflow, they were refined one by one and turned into nothingness under the blazing flames of the Super Falling Heart Flame.

This made the gray airflow, which Xiao Yan was originally quite afraid of, suddenly become an excellent tonic for nourishing his soul power.

Feeling this unexpected gift, Xiao Yan's spirits were lifted. With a smile, more Super·Falling Heart Flames emerged from his body. Like loyal guards, they shuttled in groups in this gray space, chasing and intercepting the fleeing gray airflow.

For a moment, those once arrogant gray airflows seemed to have lost their former prestige and became real stray dogs, fleeing everywhere but nowhere to hide.

Under Xiao Yan's full pursuit, one gray airflow after another was ruthlessly swallowed by the Falling Heart Flame, and then turned into pure energy and returned to the depths of Xiao Yan's soul.

This game of chasing and swallowing lasted for about half an hour, until this gray space completely restored tranquility, and there was no trace of gray airflow.

And the ferocious aura that made people palpitate also dissipated without a trace, proving that the remaining breath hidden in the jade bone wings had been completely transformed into a nourishment for Xiao Yan's soul under the refining of the Super·Falling Heart Flame.

In the vast and empty space, Xiao Yan's soul body was suspended proudly. He lowered his head to examine his soul body which was more solid and stronger than before, and a satisfied smile appeared on the corner of his mouth.

The unexpected gains from refining the remaining breath far exceeded his expectations, allowing his soul power to be substantially improved.

With the final annihilation of the gray airflow, an unprecedented transformation quietly occurred in Xiao Yan.

The bone wings, magic core and original flying fighting skills behind him seemed to have gone through thousands of trials and tribulations, and finally merged into one, turning into three pairs of dazzling, wide wings containing gorgeous flames.

These new wings vibrated slowly and powerfully, instantly triggering a frenzy of wind-attribute energy between heaven and earth, making it surging, as if even the power of nature was cheering for it.

As the wings waved lightly, the air was suddenly torn apart, accompanied by a subtle but shocking thunder roar, and a violent wind suddenly rose, the whistling sound pierced through the clouds and cracked the rocks, shaking every inch of space around.

This power not only contains the ultimate speed and agility, but also seems to be able to control the wind and clouds of heaven and earth, which is daunting.

Xiao Yan closed his eyes and concentrated, carefully feeling the majestic power contained in this new flying fighting skill.

After a moment, he slowly opened his eyes, his eyes flashing with satisfaction and excitement that were difficult to conceal.

This new flying fighting skill was so powerful that it was comparable to the level of heaven-level fighting skills!
