Ten ten-level Realm King Mechanical Puppets, this is also a very powerful combat force.

Although even if these ten mechanical puppets were combined, they were not necessarily the opponents of an Emperor Realm master.

But for most of the demons, these ten mechanical puppets are probably very powerful existences, and there are no demons who are their opponents except for some powerful realm king peak masters under the emperor realm.

However, with such extra combat power, the Demon Cloud no longer has the extra power to control other mechanical golems.

This made Qin Shaofeng's idea of creating some ordinary realm realm level mechanical puppets directly stranded.

Because without guaranteeing that the other performance of the Demon Cloud will be affected, these ten mechanical puppets are already the limit.

In terms of high-end combat power, the ten-level mechanical puppets of the Ten Realm Kings are much better than the ordinary Hundreds of Realm King Realm mechanical puppets.

But even so, this was far from enough, because Qin Shaofeng knew that judging from the price of his bounty in the Demon Clan, just with these ten mechanical puppets, it was still not very safe.

Fortunately, according to the last conversation with Bai Lao, Bai Lao said that if he completed the kill request in a month, he would not only become the seven-star war king, but also get a request to Bai Lao.

With such a request, Qin Shaofeng said at the beginning, that is, he needed a dark sky stone!

The Stygian Stone is a special spatial attribute material, but because it has the ability to shape a very strong and stable space, and it also has an unusually docile integration ability, it can be integrated into most weapons or materials for tempering.

Therefore, the price of this Dark Sky Stone is extremely high, especially this Dark Sky Stone is extremely rare, very rare, even in the base treasure house of the human race, only the Seven Star War King can barely check it.

And even if you can check it, you can't buy it.

Because the authority of the Seven-Star War King can only access the Stygian Stone, if you want to really buy the Stygian Stone, you need some conditions.

And even if these conditions were completed, the purchased Void Stone was only a very small and fast weight, which did not meet Qin Shaofeng's requirements at all.

The reason why Qin Shaofeng needed this Dark Sky Stone was to quench the Flying Feather Knife with the Dark Sky Stone, as long as it was integrated into the Dark Sky Stone, the Flying Feather Knife could store the power of other people's inner worlds, and it could store even more.

Moreover, with the spatial attribute ability of the Stygian Sky Stone, after being stored in this way, the Flying Feather Knife can completely maintain the power in it for a period of time, without the slightest waste or loss.

But according to Qin Shaofeng's previous plan, that is, the amount of Dark Sky Stone needed must not be less.

But the Dark Sky Stone that this battlefield base is currently open to Qin Shaofeng for sale, that is, a Dark Sky Stone that is a little barely the size of a finger.

According to this weight, Qin Shaofeng estimated that if he wanted to temper the Flying Feather Sword to his ideal level, he would need at least ten of these Void Stones, and this was Qin Shaofeng's situation after reducing the quenching effect of the Flying Feather Knife.

But that's not possible!

Because with the authority of the Seven-Star War King, you can buy up to three finger-sized Dark Sky Stones, which is obviously not enough at all!

So after Bai Lao put forward that request, Qin Shaofeng said without thinking about it, if he finished it, then ask Bai Lao to help buy a good Dark Sky Stone.

The final result naturally goes without saying.

Qin Shaofeng completely fulfilled Bai Lao's request, and in less than a month, he killed more than a hundred Demon Realm Kings above the Triple Realm King.

This made Bai Lao, who had been paying attention to Qin Shaofeng, a little happy in his heart.

After all, the reason for the first time this time was that Bai Lao made a bet with someone, and then Qin Shaofeng asked him to win the bet, and he was naturally happy.

At this beginning, Bai Lao prepared a good Void Stone for Qin Shaofeng.

Anyway, it was a requirement to win the bet, and Bai Lao directly won a very good Dark Sky Stone for Qin Shaofeng.

It's really nice!

This Void Stone is really, really good!

This was the first thought in Qin Shaofeng's heart after seeing the Dark Sky Stone.

At this moment, what was placed in front of Qin Shaofeng was a stone the size of a human head!

That's right, this is the Void Stone that Bai Lao prepared for Qin Shaofeng!

But that's a lot!

Qin Shaofeng remembered that in the treasure house of the base, with the authority of his seven-star war king, after completing the tedious tasks and requirements, he still needed to spend hundreds of millions of military merit points to buy a finger-sized Dark Sky Stone.

How much value will this huge Void Stone in front of him have?

Qin Shaofeng couldn't be sure of this, because the value was too great.

However, when Bai Lao handed over this Void Stone to Qin Shaofeng, Bai Lao was not unconditional.

According to what Bai Lao said, he had only prepared a fist-sized Void Stone for Qin Shaofeng before, although it was also very valuable, it was much less than the one in front of him.

And the reason why Bai Lao took out this huge amount of Dark Sky Stone was because he gave Qin Shaofeng a choice.

If Qin Shaofeng just chose a fist-sized Void Stone, then Bai Lao would have no requirements and let Qin Shaofeng play freely in this month.

And if Qin Shaofeng chose the latter piece, that is, the Dark Sky Stone the size of a human head, then Bai Lao asked Qin Shaofeng to complete the assessment within this month's time.

And in addition to the assessment, it is also necessary to elevate the cultivation to the Emperor Realm!

Otherwise, after the one-month period is over, Qin Shaofeng has not finished it, then he will completely lose the opportunity to enter the Heavenly Soldier Battle Regiment, and he will also be assigned to the battlefield in the third region to be a submachine cannon fodder.

This is a choice that Bai Lao gave to Qin Shaofeng, the former is no hindrance, and it is the same whether it is completed or not.

But if you choose the latter, the penalty for not completing it is amazing.

But at this moment, the Dark Sky Stone the size of a human head in front of Qin Shaofeng already represented which one Qin Shaofeng chose.

Failed, completely losing the opportunity to enter the Heavenly Soldier Warband?

And to go to an even more terrible battlefield and become cannon fodder?

Qin Shaofeng didn't consider any of these situations.

Because in Qin Shaofeng's view, these are things that cannot happen to him.

Although the Dark Sky Stone in front of him was indeed the reason why Qin Shaofeng made such a choice.

But this is only one of the reasons, it is making Qin Shaofeng make such a choice, and it is all because of Qin Shaofeng's self-confidence!

Completed the assessment?

And you want to elevate your cultivation to the Emperor Realm?

These things, in Qin Shaofeng's opinion, are not a problem!

Although he only has four thousand five hundred realms now, he has reached a state of complete saturation, and he is still one thousand and five hundred pounds away from the peak of the realm king realm.

In addition, after reaching the realm of the Sevenfold Realm King, only the inner world of the ten Sixfold Realm Kings can make one's one-fold realm ascend to a state of complete saturation.

Even the inner world of the sevenfold realm king of the same realm can only allow himself to raise the three-fold realm to a state of complete saturation at most.

Judging from these circumstances, it seems that to ascend to the Emperor Realm requires a large number of Demon Realm Kings' inner worlds.

But in Qin Shaofeng's opinion, there is no need to worry about it.

Because of the current situation, for Qin Shaofeng, what he lacks will definitely not be the king of the demon realm.

"With my current situation, the appearance of the Demon Realm King who has promoted me to the Emperor Realm will be enough!"

Licking his lips, a glimmer of light flashed in Qin Shaofeng's eyes.

While there were still some things, Qin Shaofeng began to refine the Dark Sky Stone, and then prepared to merge it into the Flying Feather Knife.

Qin Shaofeng knew that if he could completely integrate this Dark Sky Stone into his Flying Feather Knife, then the ability of his Flying Feather Knife would definitely be able to improve by several grades.

And the ability to store the power of the inner world of others will also be improved by leaps and bounds.

But what made Qin Shaofeng very speechless was that it seemed that because this Dark Sky Stone was too big, it seemed to be quite difficult to refine it by himself.

After three days of quenching, Qin Shaofeng had only quenched one-third of this Dark Sky Stone, and at this rate, it would take Qin Shaofeng at least six or seven days to completely quench this Dark Sky Stone.

This is the most difficult material that Qin Shaofeng has encountered after possessing the Yin Yang Dan Fire.

Fortunately, Qin Shaofeng had this Yin Yang Dan Fire, otherwise, he would probably only be able to stare at such a large piece of the Dark Sky Stone, and he would not be able to refine it at all.

The attributes of the Stygian Stone are somewhat special, because it contains very special and powerful spatial abilities, so each Stygian Void Stone is a whole.

Whether it was as small as the size of a grain of sand, or the Dark Sky Stone the size of a human head owned by Qin Shaofeng, it was an overall Dark Sky Stone.

Moreover, after the Stygian Stone is isolated as a whole, it cannot be hastily divided, otherwise, it is very likely that the spatial power of the Stygian Void Stone will be destroyed or disappear directly due to improper division.

Therefore, when refining the Void Stone, no matter how big or small, it must be tempered as a whole.

But it is undeniable that the larger the volume of this Void Stone, the greater the spatial ability contained in it, which is not comparable to ordinary Void Stones.

It's like the volume of the Dark Sky Stone that Qin Shaofeng owns, the size of a human head, compared to the volume piled up by a bunch of finger-sized Dark Sky Stones, the spatial ability contained in it is probably tens, or even a hundred times stronger!

There is simply no comparison between the two!

Although the Dark Sky Stone he obtained could make the Flying Feather Sword extremely powerful, now that Qin Shaofeng knew that this Dark Sky Stone would take him about ten days just to refine it.

If this is fused into the Flying Feather Sword after the tempering is completed, I am afraid it will take a lot of time.

"Alas, it seems that in the first half of this month's assessment time, I can only hide. ”

Feeling the progress of his tempering, Qin Shaofeng sighed softly.

Once the Void Stone begins to be refined, it must not stop.

Therefore, at this time, it is impossible for Qin Shaofeng to hunt the king of the demon realm.

But after three days had passed, Qin Shaofeng had already learned about the area around him from the detection of the Demon Cloud, and some Demon Realm Kings had begun to appear.

Moreover, the Demon Realm Kings who appeared here seemed to be above the level of the Realm King Fivefold Realm, and the number was increasing.

However, this also made Qin Shaofeng think a little.

Although there are many Demon Realm Kings now, with the Demon Cloud being there, it is impossible for him to be exposed.

Even with a little cooperation, you can still hunt a lot of demon realm kings!

Of course, Qin Shaofeng naturally couldn't do it himself.

But he couldn't, the ten tenfold realm king-level mechanical puppets around him were completely okay!
