In the girl's whisper, the wind element quickly converged.

As the last syllable fell, a wind blade that resembled a waning moon took shape.

The moment Mu Feng'er opened her eyes, the wind blade let out a soft roar, like a long knife slashing out horizontally, cutting off a three-foot-thick tree in front of her.

"It worked!"

Mu Feng'er couldn't hide her excitement and shouted.

If you take the attack power of the Xuan as a reference, the power of this magic wind blade is only at the level of the middle of the fourth level, which is far inferior to a magic skill wind blade that Mu Feng'er waved casually when she was the king, but the successful use of the wind blade means that she has taken the most critical step on the road of transforming magic.

However, to Wu Yu's surprise, after casting a wind blade with a strength equivalent to a fourth-level magic, Mu Feng'er was still in good spirits, as if the spiritual power consumed was nothing to her at all.

Although he didn't know how to divide the level of magicians in ancient times, if it was defined by the highest level of magic that could be cast, Wu Yu estimated that Mu Feng'er's spiritual power should have reached level five, and this was the most surprising point for him.

The strength of spiritual power is affected by many factors, so no one has created a systematic cultivation method of spiritual power since ancient times, but as we all know, the strength of spiritual power has a lot to do with people's state of mind.

Wu Hao suddenly remembered that the Sword Saint had said that the blood mark on Mu Feng'er's body was engraved with a large amount of blood of her loved ones when she was a baby, and then thought of Mu Feng'er mentioning that she used to have nightmares, perhaps it was this kind of pain that she didn't know, but was really hidden deep in the depths of her consciousness, that created her powerful spiritual power.

Wu Yu was very curious about how far the limit of her spiritual power could reach, but he didn't rush to take out the fifth-level magic for Mu Feng'er to try, firstly, this kind of thing could not be rushed, and secondly, they had just returned to the Xuanzhi Continent and had not yet settled down, and they didn't know what the situation was in Shengyuan Town now.

After all, there was a battle of the Emperor in Shengyuan Town, and Dongxuan Kingdom should have sent a strong man to investigate, but he and Mu Feng'er, as missing persons, reappeared three years later, and if they were recognized, it would probably cause unnecessary trouble.

Therefore, it is necessary to be vigilant until he is sure that the situation of the two of them is safe enough, and he needs to be well prepared for the worst-case scenario.

Wu Yu told Mu Feng'er his thoughts, discussed with her, and finally began with 'Wind, please listen to my call', and ended with the name of the magic, and set a spell on the several wind magics he had just selected, and the two set off to prepare to return to Shengyuan Town.

"Hearken to me, O wind, Wings of the Wind."

The slow sound of the spell sounded, and the green rays of the wind element converged behind Mu Feng'er, and a pair of cyan light wings slowly opened up as the spell fell.

With the success of the Wind Blade Magic, Mu Feng'er, who had mastered the spell-casting skills, successfully cast the fourth-level magic [Wind Wings].

Of course, it is not impossible to fly low-level magic, but Mu Feng'er's mental power is strong enough to cast and maintain the Wind Wings, so Wu Yu is too lazy to waste time with similar low-level magic.

Although strong mental power can make low-level magic exert an effect that is not weaker than that of high-level magic, the reason why high-level magic is called high-level magic is because high-level magic itself is very powerful.

Consuming the same amount of mental power, the effect produced by high-level magic is obviously stronger than that of low-level magic, just like the first-level magic [Light Body Technique], the second-level magic [Levitation Technique], and the third-level magic [Wind Walking Technique], which can also achieve the effect of flying, but compared to the fourth-level magic Wind Wing, which is faster and more agile and flexible when flying, it is obviously weak.

As soon as the wind wings spread, the two of them cut through the sky and went straight to Shengyuan Town.

Ever since Wu Hao had inspired the vision of the Holy Abyss three years ago, there had been a lot of dark aura in the Fertile Forest outside the Dragon Hidden Mountain Range.

However, three years later, the aura of darkness has not only not diminished, but has become stronger than before.

Originally, Wu Yu was going to land early after approaching Shengyuan Town, so as not to be noticed, but the closer he got to Shengyuan Town, the more obvious the dark aura became, and even Mu Feng'er, whose perception was not as good as before due to the loss of his mystical power, also noticed something unusual, so he decisively gave up his original plan, and while continuing to fly to Shengyuan Town, he vigilantly perceived the potential crises around him.

The envisaged danger did not appear, but when Shengyuan Town appeared in sight, the two of them were stunned.

The houses and streets of my memory have all been reduced to rubble, and the uninhabited ruins have been occupied by dense vegetation, and in a few years, there will be no traces of human habitation here.

"How can this be ......"

Mu Feng'er muttered to herself in disbelief.

In her mind, although the Xuantang was destroyed by a trace of power that fell from the destruction, and Shengyuan Town was also affected by the power of darkness that erupted, even if most of Shengyuan Town was destroyed, people would not abandon the homes they had worked so hard to build without nostalgia, after all, it was far more difficult to rebuild a town than to repair and repair a half-destroyed Shengyuan Town.

Wu Yu vaguely guessed something, and his gaze fell to the place where the original Xuantang was located, where there was only a huge pit left, and the surrounding dark aura came from this pit.

There was not a trace of greenery inside or outside the pit, and Wu knew it was because of the erosion of darkness.

The power of darkness has the property of destroying all things, it is a terrifying power that can easily destroy the power of the king of the wind, and it can make the source of the wind fearful.

Just as Wu Yu was explaining this to Mu Feng'er, a sharp cry suddenly came from the side.

It was a voice of anger against intruders who invaded their territory.

The two of them heard the sound, but saw five wind peregrine falcons rushing towards them like arrows off the string.

Wu Yu summoned the Wind Source Sword and swung a sword far away, and the long sword swept the wind and waves, pushing the five Wind Peregrine Falcon outward.

To Wu Hao's surprise, after he unleashed the power of Xuanli and showed his unrivaled strength, instead of fleeing in a hurry, the five wind peregrine falcons rushed over with an even more frantic attitude as if they were enraged.

The green light flickered, and the wind peregrine falcon borrowed the force of the wind and rushed towards it at a faster speed than before.

There is the source of the wind, and Wu Yu is the master of the wind.

The green light that lingered on the Wind Peregrine Falcon's body collapsed in an instant, the wind reversed, and the momentum of the Wind Peregrine Falcon's original charge suddenly stopped.

At the moment when the Wind Peregrine Falcon's bodies paused, Wu Yu saw endless chaos and madness in their eyes.

It is the result of being infected by the aura of darkness.
