The quality of the Soul Banner depends largely on the quality and quantity of Yin Souls accumulated.

Under normal circumstances, in order to refine the Soul Flag, the disciples of the Soul Mourning Sect would often use living people for blood sacrifices and extract living souls, and Duan Fei would definitely not be able to do such a cruel thing.

In particular, refining the Banner Ghost had to use a high-level cultivator as a sacrifice, which was also the fundamental reason why the Soul Banner in Duan Fei's hand had never been able to improve its quality.

But now is an opportunity, these Yin Souls are all transformed by remnant souls, Duan Fei absorbs them without any psychological pressure, and it is naturally the most suitable to use them to improve the quality of the Soul Loss Banner.

Even if a disciple of the Soul Loss Sect came to such an environment, he would be happy to regard the countless Yin Souls here as endless treasures!

It was also under the sweep of the Soul Flag, the Yin Souls were absorbed into the Soul Banner one after another, even if they didn't have time to absorb it, under Fang Yuan's active attack, they were almost crushed with one blow, and they could only let Duan Fei and Fang Yuan continue to push forward.

Obviously, just a few Yin Spirits like this, no matter how many they were, were unlikely to pose a threat to Duan Fei and Fang Yuan, so what was Fang Yuan's solemn expression for?

At least, when he easily dealt with these Yin Spirits, Fang Yuan's expression didn't relax there.

Obviously, behind these constant influx of ghosts, there must be big trouble.

Duan Fei can't take care of so much for the time being, anyway, there are so many Yin Souls to absorb, and what is there to be polite, naturally let the Soul Banner suck it to its full.

The Ice Crystal Palace was big enough, even if Duan Fei and Fang Yuan kept moving forward, it would take time to get out, so as time passed, the real big trouble finally came.

I only heard an extremely cold voice, which suddenly came out from the corner of the Ice Crystal Palace: "Who is it...... In the ...... that disturbs this seat Sleep ?!!"

With the sound of this voice, a white mist rose from the corner of the palace, and soon condensed into a huge yin soul that was a few feet high.

In fact, since the appearance of this tall Yin Soul, there have indeed been some unusual changes, although there are still Yin Souls gushing out in all directions, but those Yin Souls passing by the tall Yin Soul are like encountering a magnet, and they are directly absorbed and devoured by the tall Yin Soul, turning into the energy in the body of the tall Yin Soul.

The existence of this tall Yin Soul is like being able to play the role of a Soul Flag, and the more Yin Souls there are, the more Yin Souls there are, for the tall Yin Soul, that is its endless source of power.

It's no wonder that the tall Yin Soul is so angry, Duan Fei waved the Soul Banner to absorb the Yin Soul, this is like snatching food from its mouth, how can this be tolerated?

Moreover, the ordinary Yin Soul is more like a gathering of cold qi, which has no substantial body, but the tall Yin Soul is different, the Yin Qi in its body is extremely compressed, and its misty body has turned into a special form of half mist and half solid.

Even if the tall Yin Soul hasn't made a move yet, judging from the aura it emits, it at least has the strong strength of the late stage of the Spirit Gathering Realm!

After the tall Yin Soul appeared, it took the initiative to pounce on Duan Fei, and it seemed that Duan Fei's move to absorb the Yin Soul had indeed angered this big guy.

At this time, Duan Fei's righteous qi and fire supernatural powers had not yet entered the cooldown period, and there were at least two or three minutes of time to exert his power, but the tall yin soul rushed over at this time, just enough to let Duan Fei's explosive supernatural powers exert their residual power.

The most powerful weapon of the tall Yin Soul is that it can attack the cold aura in his body as if it had turned into substance, for example, as soon as it opens its mouth, the cold aura can shoot towards Duan Fei like a sharp arrow.

Moreover, when this air arrow slashes through the air, all the Yin spirits that are touched by it will be absorbed by the air arrow, so that after the air arrow is shot, it will become more and more powerful as the distance is extended.

Such a special means of attack, for the tall Yin Soul, can be regarded as giving full play to its home advantage, as long as there are countless Yin Souls in the four corners, then it has enough energy to replenish, and it can become stronger and stronger.

Of course, just such an air arrow attacking was nothing to Duan Fei, and he had a way to deal with it.

I saw that when Duan Fei's mind moved, he immediately used the magic power of the cold word formula, at this time he was in a state of explosion, the power of this cold word formula was even more extraordinary, even if the air arrow spewed out by the tall yin soul itself was condensed by the cold breath, but it was still affected by the cold word formula.

It can be clearly seen that on the outer surface of the air arrow, a layer of ice crystals was quickly frozen, which was equivalent to isolating the inside and outside, so that the air arrow could no longer absorb the Yin Soul to enhance its strength.

Moreover, after the air arrow was hung with such a layer of ice crystals, its speed slowed down significantly, and it even swayed in the air, as if it would fall down at any time, how much power could it be left?

Duan Fei's method at this time was not only the cold word trick, he also used the array word trick, and after combining the power of the Five Elements Sword Formation, he directly strangled the air arrows that shot over.

Even without using the Five Elements Banner, the power of the Five Elements Sword Formation was extremely good, and after the speed of the air arrows was affected, how could they escape the joint strangulation of the five flying swords?

In the blink of an eye, the air arrows were completely crushed, turning into countless scattered cold qi that spread to the surroundings, but all the Yin Spirits that came into contact with it would be frozen in an instant, turning from invisible to tangible, falling from the sky like hailstones.

In the face of these frozen Yin Souls, Duan Fei didn't let them go to waste, and directly rolled up the Soul Banner and put all of them into the flag, no matter whether these Yin Souls were frozen or not, they could become the energy absorbed by the Soul Flag.

Duan Fei's move undoubtedly further angered the tall Yin Spirit, only to hear a scream from its mouth, and no longer used any indirect means, but took the initiative to pounce towards Duan Fei.

Duan Fei still looked very calm at this time, he just waved his hand lightly, and the Five Elements Sword Formation moved towards the tall Yin Soul, even if it couldn't be easily strangled, it was no problem to restrict its movements.

As long as the tall Yin Soul couldn't get close to find trouble for a while, then Duan Fei could not care about it and continue to wave the Soul Banner very calmly to absorb those scattered Yin Souls.
