Xia Fan stood aside and did not release the fierce spirits and demons to help in the battle.

Because Xia Fan knew that Dudu and her souls needed to go through such a battle in order to be able to adapt to the fighting methods of the netherworld faster and better.

In this way, Xia Fan was able to rest assured that Dudu and his souls would be able to develop freely in this netherworld.

The Netherworld was huge, not only was it much bigger than the small thousand worlds he had experienced, but even the middle thousand worlds in his current Heaven Swallowing Pocket were still a little small compared to them.

This means that even if Xia Fan wants to take this netherworld for himself, it is impossible to simply and rudely swallow it with the Heaven Swallowing Pocket.

It's not that Xia Fan doesn't want to, but he can't do it. At least until the Sky Swallowing Pocket has completely grown to the point where it is enough to swallow a large world at once, it is estimated that it will not be able to do it.

In this way, if Xia Fan wants to get this netherworld, he must fight one battle after another, and conquer one place after another.

But Xia Fan's biggest trouble at the moment is that he doesn't have that much time to fight here, and the alliance of the three clans in his hands is actually not suitable for this.

Although the alliance of the three clans can stay and fight in the Netherworld for a short time, if they stay too long, it is difficult to guarantee that there will be no problems under the infection of dead qi, corpse qi and yin qi.

In addition, if you want to conquer this world, there will inevitably be battles, of course, casualties are inevitable, and the living are the most disadvantaged to fight here, even if it is a powerful alliance of three clans.

Xia Fan thought about it, and finally felt that the most suitable person to stay here was precisely Dudu and her soul body.

Here, the souls are like fish in water, and their strength will increase quickly, and even if they are injured in battle, they don't have to worry about being infected by death qi and turning into walking corpses.

The only thing that made Xia Fan a little uneasy was that Dudu had always stayed by his side, although he had participated in some battles before, but after all, he had never been on his own.

And Xia Fan wants to keep Dudu in this netherworld this time, if she can't hold the situation, then many plans based on this netherworld will be impossible to talk about at all.

For this reason, Xia Fan has only now decided not to interfere in this battle, and to see if Dudu can deal with an enemy like Gu Xiaoyun on his own and those souls.

If he can, Xia Fan can rest assured that he will implement the follow-up plan.

"Woo woo woo ......" Gu Xiaoyun obviously didn't expect those skeleton cavalry and nether beasts to defeat Dudu alone, so he reached out and grabbed it, as if he had pulled out a whip with a length of one hundred and ten zhang from the void in front of him, and whipped it towards Dudu.

Not only was the color of this long whip white, but the sound of breaking through the sky was also different from that of ordinary whips, and the sound was whimpering, as if countless unjust souls were crying in the bleak cold night. It sounds extremely miserable and creepy.

In fact, this whip is not an ordinary thing, and the whip body that seems to have failed miserably is actually made of skulls one by one.

None of the owners of these skeletons died at the end of their lives, almost all of them died horizontally, so of course they were resentful when they died, and they were refined into this evil weapon, and they could not be reborn forever, so the resentment was naturally even stronger.

After that, the death qi, corpse qi and yin qi in this netherworld continued to infect, so that all the skulls became first-class ferocious things.

Even if a Grandmaster Realm powerhouse is drawn by it, it will inevitably be invaded by the resentment and death qi contained in it. Although it may not be fatal, it can disturb the mind and hurt the soul.

If you are on the soul body, this skeleton whip is even more powerful, and when it is drawn, the fierce ghast spirit in the skeleton directly pounces and bites wildly, and the damage caused to the soul body is far more serious than being cut by a sword or something, because it will directly damage the soul body, and it will never be able to recover if it is serious.

Of course, Dudu could see the power of this skeleton whip, so he naturally didn't dare to let it get close, and with a wave of his right hand, the Heavenly Demon Banner had already roared out.

Although the Heavenly Demon Banner is owned by Xia Fan, Dudu can also be used at will, and even the magic of its use is often not much inferior to Xia Fan.

"Bang ......" The Heavenly Demon Banner waved in the wind, and the long banner danced, like a huge screen in mid-air, directly blocking the skull long whip.

Although the skull whip was powerful, the resentment and death qi on it could not help the Heavenly Demon Flag, which was also tempered from the sea of blood in the corpse mountain

As a result, the skeletal whip that came quickly was directly shaken and rolled back.

At this moment, the Heavenly Demon Banner that had just blocked the rapid blow of the Skeleton Long Whip suddenly collapsed, turning into a ninety-nine eighty-one Ten Thousand Soul Banner and shooting out, forming a formation in the blink of an eye.

The scope of this formation is not large, only a dozen miles in radius, but it just encloses Gu Xiaoyun in it.

Gu Xiaoyun never expected that Dudu would suddenly set up a formation during the fight, and all this happened so fast that it was too late when she wanted to escape.

"What kind of formation is this?" Gu Xiaoyun held a skull whip in his hand, protecting his body, squinting his eyes at the formation that trapped him, but she let her look at it for a long time, but she couldn't even find the slightest flaw.

This formation was taught to Dudu by Xia Fan, and when the ninety-nine eighty-one Ten Thousand Soul Banners formed a formation, the space in the formation was temporarily separated from the surrounding space.

This is like making the person who enters the battle a turtle in an urn, and it is difficult to escape easily.

In fact, this formation is not just used to trap the enemy.

As Dudu hit a series of spells on top of the formation, the ninety-nine-eighty-one Ten Thousand Soul Banners shook slightly.

Xia Fan comprehended a lot of spatial spells from the Boundary Breaking Bell, and integrated some of these insights into the Ten Thousand Soul Banner. This allowed each Ten Thousand Souls Banner to shake the void and tear the surrounding space apart.

Although the scope of space that each Ten Thousand Souls Banner could tear was limited, when the eighty-one Ten Thousand Soul Banners were linked, they shook the void together, and the destructive power caused was quite amazing.

This process is actually similar to when the Boundary Breaking Bell was first rang by Xia Fan with all his might.

The difference is that most of the destructive power of the original Boundary Breaking Bell is spreading outward, but the destructive power that erupts from the current Ten Thousand Soul Banners is pouring into the formation.

The earth-shattering sound of "Boom ......" suddenly erupted, and at the same time, the space in the formation formed by the Ten Thousand Soul Banners was like a crystal that had been violently exploded by a huge force, and it was instantly shattered.

Gu Xiaoyun was in the array, but he had a feeling that the heavens were falling apart and the world was collapsing. Since he died, he has never had fear, and there is even a trace of long-lost fear in his heart.

It's just that Gu Xiaoyun can't take care of savoring this rare feeling at this time, because if she doesn't hurry up and do something, she will really be finished.

At the moment of danger, Gu Xiaoyun showed her extraordinary calmness, and as soon as her mind moved, the skeletal whip rolled back, flying around her like a coiled dragon, helping her resist the strong impact caused by the collapse of the space around her.

"Bang bang bang ......" It's just that how could this skeletal whip compete with the huge destructive power that erupted from the spatial collapse, so that it burst one after another after exceeding the limit of bearing.

"Ahh......h

When the skull whip was less than half as long as it was, the collapse of the space in the array finally stopped.

It's not that Dudu doesn't want to completely kill Gu Xiaoyun in one fell swoop, but that Fang Cai's blow has consumed more than thirty percent of her mana, if it continues, it's good to be able to kill Gu Xiaoyun, otherwise she will completely lose the power to fight back.

Although Xia Fan was next to her, Dudu didn't want to ask the young master for help too much, she really wanted to defeat Gu Xiaoyun with her own strength.

", I thought you were strong, but I didn't expect it to be like this. Gu Xiaoyun escaped death, not only did he not have any joy in his heart, but he was full of indescribable anger and killing intent.

As he spoke, he had already swung his skeletal whip and slammed it into the void around him.

"Bang ......" Although Dudu no longer urged the Ten Thousand Souls Banner to shake the void, he did not withdraw the formation. Therefore, Gu Xiaoyun was still trapped in the formation.

Now Gu Xiaoyun pulled out a whip, and the whip shadow shot out, stretching thousands of zhang away in an instant, hitting the void with a loud rumbling sound, like thunder, the energy was agitated, like a tsunami, impacting the surroundings, and of course, it also shook the formation.

Gu Xiaoyun himself has the strength of the late stage of the Grandmaster Realm, and now in order to get out of trouble, he is doing it with all his might, and every time he whips out, the formation is flickering.

Gu Xiaoyun's move is actually quite ruthless. She couldn't find a flaw in the formation, so she simply didn't plan to look for it, but relied on her own strength to be strong enough to blow up the formation.

If it was Xia Fan who was in control of the formation at this time, then Gu Xiaoyun would basically be useless at all except for consuming his own mana, but it would still be quite useful to Dudu, who was slightly inferior in strength.

For the current Dudu, the lack of mana is her biggest shortcoming, and whether it is to urge the formation to attack and defend or keep it running, it needs to consume her mana.

Now Gu Xiaoyun's crazy attack formation is actually equivalent to constantly weakening Dudu's strength. When her mana was exhausted, the formation would naturally no longer be able to sustain it.

Xia Fan saw through Gu Xiaoyun's purpose, but he didn't say anything to remind him. Because he really wanted to see if Dudu could realize Gu Xiaoyun's calculation in time and how he would deal with it?

Dudu did not disappoint Xia Fan, she immediately sensed Gu Xiaoyun's plan, so she no longer thought about trapping him by the formation, but rushed over directly, reached out and grabbed the two Ten Thousand Soul Flags and stabbed towards Gu Xiaoyun.
