Although Qin Shaofeng himself comprehended and refined the Dark Sky Stone, he couldn't do it himself.

But there are ten mechanical puppets of the Tenfold Realm King level, and this hunting of some Demon Realm Kings is not a problem at all.

Even because of the gradual increase in the number of realm kings in this area, they all exist in the form of squads, which leads to the ten mechanical golems hunting very smoothly.

Think about it, too!

These Demon Realm King Squads are fifteen or sixteen realm kings at most, and most of the demon realm kings who have cultivated to be the best are only in the realm of eightfold and ninefold realm kings, and only a few dozens of realm kings appear.

However, in order not to expose the mechanical puppet, and in order not to let the demon clan notice the abnormality, Qin Shaofeng just asked the mechanical puppet to hunt the team led by the Demon Realm King of the Seven or Eight Realms.

With Qin Shaofeng's current sevenfold realm of more than four thousand five hundred saturated realms, he now absorbed the inner world below the sixfold realm realm, and there was no effect on him.

Although it is not to say that there is no improvement effect at all, it would take at least a hundred Demon Realm Kings of the Sixfold Realm to raise the first realm of his inner world to the saturated and perfect realm, and then merge with the first realm.

Even the Demon Realm King of the Sixfold Realm needed at least ten Inner Worlds to allow Qin Shaofeng's Realm to reach the realm of saturation and perfection.

Moreover, even if it was the inner world of the Sevenfold Demon Realm King of the same realm, at most, he could only raise the three-fold and five-fold realms to the realm of saturation and perfection.

Although the inner world of the eight-fold, ninfold, and even tenfold demon realm kings can be improved even more.

However, because of the need to maintain the situation of refining the Void Stone, it was not easy for Qin Shaofeng to absorb too much and too strong the inner world at one time.

Therefore, Qin Shaofeng let the mechanical puppet only target the demon team that was not very powerful.

Then, the mechanical puppet team hunted, captured or hunted the Demon Realm King, and brought it back to Qin Shaofeng to absorb the inner world and improve his own realm.

Although this speed was much slower, it was far less fast than absorbing it with all his might, and because refining the Void Stone required a lot of energy, it also made Qin Shaofeng waste a lot of strength while absorbing the inner world of those demon realm kings.

Therefore, in general, even if there were enough Demon Realm Kings, Qin Shaofeng's cultivation speed during this period of time was still much slower.

But even so, when Qin Shaofeng had completely refined the Void Stone, that is, six days later, Qin Shaofeng's realm had still been raised to the Eightfold Realm King realm.

In the Eightfold Realm King Realm, more than four thousand eight hundred realms in the inner world have reached the realm of saturation and perfection, and one thousand of them have already been fused with yin and yang.

This made Qin Shaofeng's strength a little improved.

However, what made Qin Shaofeng most pleased was that while his realm was improving, the Yin Yang Dan Fire in his body had also improved a lot.

This made Qin Shaofeng's speed in refining the Dark Sky Stone also increased a lot.

And what Qin Shaofeng cares about the most is that because of the improvement of the Yin Yang Dan Fire, the next process of integrating the quenched Dark Sky Stone into the Flying Feather Knife will also be much smoother.

"Well, with the current power of the Yin Yang Pill Fire in my body, this fusion will only take three or five days at most. ”

Seeing that under his Yin Yang Dan fire, the Dark Sky Stone, which had been tempered into a ball of pure power, was slowly merging into the Flying Feather Knife without a trace of hindrance, the corners of Qin Shaofeng's mouth curled slightly, and a trace of excitement, a trace of anticipation, and a trace of excitement flashed in his eyes.

If such a huge Void Stone is completely integrated into the Flying Feather Knife, how will the Flying Feather Knife improve?

Moreover, this time he re-refined the Flying Feather Knife, Qin Shaofeng didn't just simply integrate this Dark Sky Stone into the Flying Feather Knife.

Because of the integration of the Void Stone this time, this led to the ability of the Flying Feather Knife itself to contain space, which was also directly improved a lot.

This allowed Qin Shaofeng to finally be unscrupulous, and according to his previous thoughts, he could add other materials to the Flying Feather Knife.

Even if it weren't for the fact that he didn't have the Divine Tattoo in his hand, Qin Shaofeng would have wanted to directly integrate the Divine Pattern into the Flying Feather Knife, so that the Flying Feather Knife would be promoted to an artifact.

And once there is a divine pattern, with the previous quality of the Flying Feather Knife, this can also be integrated into at least three divine patterns, which is enough to make the Flying Feather Knife step up to the level of a high-level artifact.

Even after this fusion of the Void Stone, Qin Shaofeng was confident that the Flying Feather Sword would have the quality of becoming a treasure.

What a treasure!

Just thinking about it, Qin Shaofeng felt very excited.

Because of the heavy treasure-level flying feather sword, in his own hands, he can definitely have the power to kill any realm king realm master below the emperor realm in seconds.

It's a pity that now such a thing can only be thought about.

Because the god tattoo is not easy to obtain.

The existence of the divine pattern is the power of its own realm, the power of the avenue between heaven and earth, and the power condensed from the avenue with its own power.

That's not a small difficulty, and usually only some powerful Nirvana Realm masters can condense the divine pattern.

And even if it is a divine pattern condensed by a Nirvana realm master, it is also an ordinary divine pattern.

Such a divine pattern can be purchased with military merit points in the base treasure house, and with the authority of Qin Shaofeng, the seven-star war king, it is just to the point of purchasing a divine pattern.

But Qin Shaofeng didn't want to do this, this is not to say that the divine pattern of the base treasure house is too much.

On the contrary, the god pattern of the base treasure house is very cheap.

It's really cheap, and even some extremely basic god patterns can be purchased for millions of military merit points.

But this kind of divine pattern is too low-grade and too ordinary.

The artifact refined with such a divine pattern is also very powerful, and it is only the most powerful artifact.

The artifact that Qin Shaofeng saw from the treasure house of the base before, that is, the kind of artifact worth tens of millions of military merit points, was an artifact of this grade.

But such an artifact, but in terms of quality, is far inferior to Qin Shaofeng's Flying Feather Knife!

The power is limited!

Qin Shaofeng naturally didn't want to make his Flying Feather Sword such an artifact.

Therefore, Qin Shaofeng had to be careful about the divine pattern that his flying feather knife had integrated, even if he didn't integrate the extremely strong divine pattern, it would definitely not be too bad.

At the very least, in line with the flying feather knife itself, some better-grade divine patterns should be organized.

It's just a pity that in the treasure house of the base, there are only ordinary god patterns for sale.

Of course, this does not mean that the treasure trove of the Terran battlefield base only has such a god pattern for sale, and there must be a high-grade powerful god pattern.

It's just that Qin Shaofeng knows very well in his heart that with his current identity as a seven-star war king, the divine pattern that can be purchased is estimated to be just such a divine pattern.

Maybe when you really enter the Heavenly Soldier Warband, you will be able to buy a more powerful Divine Tattoo, right?

As soon as he thought of this, Qin Shaofeng's speed of refining the Flying Feather Sword accelerated even more.

Strive to complete the refining of the Flying Feather Sword as soon as possible, because Qin Shaofeng knew that even without the integration of the Divine Pattern, as long as his Flying Feather Sword was integrated into this Dark Sky Stone, the power would be absolutely terrifying.

And the most important thing is to absorb more inner world power, so that it is enough to improve yourself quickly.

In this way, it is good to successfully complete the Bai Lao assessment, and then join the Heavenly Soldier Battle Group.

Just as Qin Shaofeng was refining the Flying Feather Sword tightly and orderly, the battlefield entry passage on the Demon Domain side finally ushered in a big man.

This is the ancestor of the Blade Demon Clan!

In order not to let himself leak a trace of news, this Blade Demon Clan Ancestor was very cautious.

A matter of such a large amount of refining materials is a big deal for the Blade Demon Clan, and the Ancestor of the Blade Demon Clan naturally attaches great importance to it.

Therefore, on the premise of keeping his identity not revealed, his speed of moving forward was naturally a little slow.

After talking for a few days, I came to the battlefield entry channel.

But that's the end of it.

Because as soon as he enters the battlefield, then he does not need to hide himself so carefully.

At most, it is to hide its own realm and not let the human race side notice it.

As far as the situation where he had reached the peak of the Emperor Realm twice, this hiding his aura could not be simpler.

The ancestor of the Blade Demon Clan is confident that with his own ability, once he hides it, unless he is a powerhouse of the Nirvana Realm who comes in person, or an Emperor Realm master of those special races in the Ancient Sacred Domain.

Otherwise, no one would have been able to find him.

But this time when he entered the battlefield, he didn't go to the core of the battlefield in the seventh region, but just a place close to the core area.

That place is not like the Demon Domain on his side, there will be some powerful Nirvana Realm masters, and he can move forward at full speed.

The danger seems to be getting closer!

……

Three days later, Qin Shaofeng finally ended his retreat.

In the end, the process of integrating the quenched Void Stone into the Flying Feather Knife was even better than Qin Shaofeng expected, the speed was very fast, and the process was also very smooth, without the slightest obstacle or twist and turn.

Even if it weren't for Qin Shaofeng's final integration of many other precious materials, Qin Shaofeng would have been able to end this retreat refining as early as a day and a half ago.

The re-refined Flying Feather Knife is no different in size from before.

It was as thin as a cicada's wing, with a silvery sheen!

However, in addition to emitting a trace of silver light, the entire thin blade of the knife has a crystal clear vision, as if it is a transparent knife.

Even if Qin Shaofeng did it deliberately, he could completely weaken the existence of the Flying Feather Knife itself, and between the flashes, at most it was a faint silver light that was fleeting.

If you don't pay attention to this, you won't be able to detect the existence of the Flying Feather Knife at all.

These are the abilities that come with the Stygian Stone!

After adding the Stygian Stone, the Flying Feather Knife not only has an extremely strong storage capacity, but even its own holding capacity, but also under the transformation of the special spatial attribute ability of the Stygian Stone, it has become even better.

And the most surprising thing for Qin Shaofeng was that after completing the integration into the Void Stone, the faint silver light emitted by the Flying Feather Knife itself shone brightly, as if it had drawn some kind of pattern!

God Tattoo!

That's right, it's the god pattern!

I don't know if after all, the Flying Feather Knife has been raised to the limit of the limit at the level of the god-level spiritual weapon, or because of the addition of such a huge Stygian Sky Stone, which caused the Flying Feather Knife to evolve a divine pattern on its own.

It's just that the evolved divine pattern of this single does not seem to be complete, and its own faint god-like state has not been completely formed.

The Flying Feather Knife is still a god-level spiritual weapon at the moment, and it has not become a promotion artifact, which also shows this.

At most, it is a half-finished divine pattern!
