It would be good if the distance between the two worlds was closer, and Xia Fan's strength would be able to support the consumption of the earth. But if the distance between the two worlds was too far, he was really afraid that he would run out of mana and die before he reached the other side.

If a magic weapon has such great drawbacks that it is enough to endanger life, it is obviously not enough.

The second is that a large number of materials are needed to refine the Boundary Breaking Bell.

At the beginning, Xia Fan was able to make it all together, most of which was due to the blessing that the swallowing worm had a lot of materials in its stomach that it could not digest, which was equivalent to picking up a big bargain.

It's just that now the Sky Swallowing Worm has been dead for a long time, and the space in the stomach has been cleaned up by Xia Fan many times. How many materials there are Xia Fan's hearts. Even if he was willing to take out all these materials and use them, in fact, he would not have enough of the materials he needed.

As the so-called Qiao woman is difficult to cook without rice, there are not enough materials, even if Xia Fan is very capable, it is impossible to make something out of nothing, so his plan to refine the Boundary Breaking Bell again was rejected by him.

After thinking about it, Xia Fan had the final decision, that is, to rerefine the Sky Swallowing Bag.

Of course, when it is said to be re-refined, it is actually not a re-refining of the inside and outside of the Sky Swallowing Pocket.

First, there is no need for this, after all, when Xia Fan refined the body of the Sky Devouring Insect into a Sky Devouring Bag, it can be said that he did his best, and almost tapped its due potential, even if it can be rerefined now without causing damage to it, there will not be too many changes.

The second is that if you really want to change it, then there are too many people and things involved.

You must know that there is not only a small thousand worlds in the Sky Swallowing Pocket now, but also a total of more than a million demon clans and multi-armed clans, plus the mountains and rivers they live in.

Of course, it was easy for Xia Fan to put it in, but if he wanted to release it again, it would not be so simple.

Besides, there is not much benefit in tossing around like this, of course Xia Fan will not do such a thankless thing.

Although there is not much improvement in the Sky Swallowing Pocket, there is still a place outside the Sky Swallowing Pocket that can be put to good use, and that is the single horn of the Sky Swallowing Worm.

The Sky Swallowing Worm has a single horn, is indestructible and sharp, and can easily tear through the void, which is one of the biggest reliance of the Sky Swallowing Worm to shuttle through the void.

When Xia Fan used the body of the Sky Swallowing Worm to refine the Sky Swallowing Bag, he kept this single horn very completely, and at the same time did not refine it too much, because he didn't think about how to use it at that time.

Later, when Xia Fan rolled up the Sky Swallowing Pocket and used it as a weapon temporarily, this and the unicorn also used to exert considerable power. It's just that seriously, it's still a bit overkill.

It is precisely because of this understanding that Xia Fan has reached this single horn this time, wanting to give full play to its due power and role.

In fact, refining a single horn alone without damaging the entire Sky Swallowing Pocket is really not a small difficulty.

However, Xia Fan decided to give it a try after careful consideration. Because for him it is not only a challenge, but also a rare improvement.

If it succeeds in the end, not only will it be able to greatly increase the quality and power of the entire Sky Swallowing Pocket, but it will also greatly improve the refining attainment. Kill two birds with one stone, why not.

As for what would happen if he failed, Xia Fan didn't think about it at all. It's good to think about defeat before you win, but it's not a better way to move forward with success as the only goal.

After Xia Fan walked into the quiet room, he first used the Ten Thousand Soul Banner to lay down a formation to isolate the surroundings, but he was afraid that the flames he used when refining the weapon were too blazing and spread to the surrounding houses.

Immediately, Xia Fan took out the Sky Swallowing Bag, released his divine thoughts, and carefully examined the single horn on the bag, and then flicked his fingers, and two flames, one red and one black, flew out, and began to circle and dance around the single horn, like a dragon around the pillar.

When refining the Sky Devouring Pocket at the beginning, Xia Fan not only used flames, but also used Xuanyin Ice and Fire. Now it's replaced by the Silent Demon Fire. Although the flame is different, the quality has improved a lot.

Refining weapons with two flames at the same time was nothing new for Xia Fan, so he was very familiar with it.

In addition to urging the Flame and the Silent Demon Fire to continuously smelt the unicorn and clean up the impurities in it to the greatest extent, Xia Fan's fingers moved frequently, constantly throwing all kinds of rare materials in his Qiankun bag into the flames.

As the flames burn, the material quickly melts, and the impurities are removed and fly away in wisps of smoke.

When the materials fused together, the flames receded, but the Flame of Silence shrouded the materials again for a second smelting.

This process didn't last long, as the material was so pure that it no longer had any qualifications, Xia Fan's fingers flicked a few times, and the flames joined again, constantly colliding and intertwining with the Silent Demon Fire, stirring the material that had turned into liquid like two hands.

At this time, Xia Fan's hands quickly pinched, forming a series of magic tricks to hit the material.

These spells contain a lot of runes condensed from the fragments of the laws of space, and at this time, under the continuous fusion with the materials, they begin to affect each other, humming softly, and constantly shaking the surrounding space.

Seeing this, Xia Fan didn't stop checking, but instead played more tricks faster and faster. However, the Flame and the Demon Fire of Silence are constantly helping it stir up the materials and sort out the tricks that are incorporated into them, so that they can better play their due role.

It wasn't until Xia Fan injected tens of thousands of magic tricks into the material that the liquid material that originally showed a silver-white color had already shown a crystal and translucent color, as if it was a crystal, but it shone with a certain indescribable color, which made people can't help but be attracted by it at a glance.

"Yes. Xia Fan snorted lightly, and the magic tricks first stopped, but suddenly they hit hundreds of thousands of magic tricks like a raging storm.

The Flame and the Demon Extinguishing Fire moved, rolling up the material like two tiny fire dragons, and wrapping it directly around the horn of the Sky Devouring Pocket.

Although the material melts into a liquid state, it is still quite viscous, but when it comes into contact with the unicorn, it flows down the unique texture of the unicorn like clear water, and is continuously absorbed by the unicorn and quickly merges.

When the material and the unicorn are combined, the magic that has been integrated into it is also imprinted on the unicorn, forming one mysterious but magical rune after another.

These runes were all condensed from the fragments of the laws of space. Each rune is powerful in its own right, and when it is linked to other runes, it will burst into even greater power.

Once the material flows from the tip of the unicorn to the end, it is completely fused with it. At this time, the unicorn began to flicker with brilliant light, and those runes also lit up, making a slight humming sound, and when the more and more dazzling light rippled in all directions, the void in the quiet room suddenly shattered.

In the sound of the "bang ......" explosion, the originally intact void was like glass shattered by a loud sound, and it directly burst into countless pieces.

At the same time, the spatial turbulence surged in and began to wreak havoc around it frantically. The floor of the quiet room was reduced to powder on the spot, and the foundation and soil below were also damaged.

Not only that, but the spatial turbulence also rushed towards the surrounding formations, making a deafening sound under the violent impact. Although it was blocked back by the formation formed by the Ten Thousand Soul Banners, it still continued to impact upward.

Fortunately, Xia Fan had previously arranged a formation out of caution, otherwise not only would the quiet room have been destroyed at this time, but he was afraid that the entire Generalissimo Mansion would be razed to the ground.

"Smack!" Xia Fan snapped his fingers.

In the next moment, the light above the unicorn converged, the shattered void returned to its original state, and the turbulence of the surrounding space gradually calmed down without the support of the force.

It's just that Xia Fan glanced at the wolves all over the ground and the big pit that was already three or four hundred zhang deep underground, and still couldn't help but smile bitterly.

Although the spatial turbulence can't hurt him in the slightest now, it is still quite powerful for the destruction of the surrounding houses or something.

Xia Fan waved his hand lightly, and the aura of heaven and earth moved with it, pouring into the big pit underground, and then the soil gushed out, quickly filling the big pit. It looked a little rudimentary without the previous baseplate, but at least it was able to stand normally.

Reaching out to take the Sky Swallowing Pocket in his hand, Xia Fan glanced at the unicorn that seemed to be ordinary but had a flash of light from time to time, and was very happy in his heart, because his idea had finally become a reality.

"I just don't know if this unicorn can really work as well as I expected?" Xia Fan thought to himself, and couldn't help but want to give it a try.

It's just that Xia Fan doesn't know much about the ready-made spatial orientation, and Xia Fan already has an idea in the blink of an eye.

"Buzz ......" As Xia Fan dodged into the Sky Swallowing Pocket, the runes on the single horn began to change positions rapidly as if they were alive, and the light on the same single horn flickered, and even the Sky Swallowing Pocket was shrouded from top to bottom.

"Bang ......" The next moment, the void in front of him was directly torn through, and then the Sky Swallowing Pocket plunged into the deep and pitch-black space as if it was a rejuvenated Sky Swallowing Worm.

Although Xia Fan was in the Sky Swallowing Pocket at this time, his divine thoughts were attached to the unihorn and he glanced at the scene outside.

To be honest, he was curious about what it was like to navigate through the void. I didn't have a chance to learn about it before, but now, of course, I want to see it.

Speaking of which, all worlds are actually located in the void, but the two are the surface of each other, each world is exposed and can accommodate all kinds of creatures, while the void is hidden, which is equivalent to being between the cracks of various worlds.

Although the Void is a gap between the worlds, it is not small, on the contrary, it is vast and dangerous, because it is full of all kinds of void turbulence, spatial rifts, countless stars and meteorites, and so on.

There are not no creatures that can shuttle and survive in the void, but all of them are overlord-level fierce beasts with strong strength and vitality, so idlers will never dare to provoke them.

Strictly speaking, the Sky Swallowing Insect is actually such a fierce beast. It's just that he was raised and scrapped at first, and then he met Xia Fan again, and finally became a material for refining miserably. Otherwise, if it really grows up, even with Xia Fan's current strength, he won't dare to provoke it.

Although the void is dangerous, it is not a Jedi that cultivators cannot set foot in, but if they want to enter here, if their strength is too poor, they will definitely die nine or even ten deaths, and if they want to save their lives under the violent void turbulence and various meteorites that fly by from time to time, at least they have to ask the Dao realm.

Otherwise, if you rush into this place, it will really be like gambling on luck.
