After arranging everything, Yun Feng began to concentrate on completing the last process of the sky core, and at the same time, he was also planning to secretly follow him over to witness the rise of the elf clan sky city, which is a good landscape. Pen & Fun & Pavilion www.biquge.info

Holding the potion bottle in his hand, Windsor was entangled in his heart, to be honest, there are many magic or other strange methods on the continent that can be done through a person's blood, the lighter ones can directly sense the location of the blood owner through the blood, and the more serious ones can even directly control a person's life and death power through the blood!

Although the slave contract was no longer valid for some reason, the human race would never give up the extremely lucrative trade of the slave trade, and if this Yunfeng used Olenna's blood to do something unsightly, it would be serious.

However, among the forgers, the experience of forging equipment for a cherished attribute cultivator like Olena was indeed very scarce, and she didn't know if she had to entrust someone's blood to assist in forging.

If a mage does not have the support of matching equipment, the strength that can be exerted in battle is only fifty percent at most! It is only slightly stronger than a full-equipment mage who is one level lower.

After thinking about it, Windsor walked up to Olena with the potion bottle, and after a whispered conversation, she got a full bottle of blood.

The capacity of a potion bottle is actually very small, and the total capacity is only one-third of a regular test tube, taking out so much blood is nothing to a cultivator, Olena didn't even frown.

When Windsor walked to Yun Feng's side with a bottle of blood, there was also a flash of light in front of Yun Feng! Then a white cube full of science fiction colors appeared in front of Yun Feng.

The whole cube is full of brilliant white light, and under the white light, light blue light flows back and forth on countless stripes like blood, like a living heart!

It had been hard for Windsor to imagine how the huge Sky City could float with the palm-sized cube on the drawings, but when she actually saw the perfect core of the sky, all doubts had vanished.

A cube the size of a palm, the energy fluctuations emitted were no less than those of dozens of god-level powerhouses! What's even more terrifying was that the energy fluctuations of the Heart of the Sky were still growing!

"It's really worthy of being an ancestor-level race of alchemy, and it can actually use these low-grade materials to create such a powerful equipment through subtle matching! If it weren't for the fact that this sky core has no means of attack and defense, it wouldn't be an exaggeration to call it an artifact!" Looking at the heart of the sky in front of him, Yun Feng couldn't help but sigh.

Yun Feng had no doubt that as long as they followed the development time of this world for hundreds of thousands of years, they would definitely be able to develop into a powerful plane that was not weaker than the future world!

Of course, the current world is like a scientific and technological civilization that is locked by a god-level civilization that restricts the development of science, and they are locked by a god-level civilization on the path to ascend to the stronger, but Yun Feng has a feeling that the reason why he came here inexplicably should be to help them unlock this blockade.

This feeling is not inevitable, but an inexplicable sense of mission, when he knew that the world was blocked, he had this feeling, he once wanted to escape, but if he wanted to go back, he had to break that confinement!

Because before the tenth level, even if he had a passage to be able to return to the future world, the little spiritual power he had left would be torn apart by the tearing of the spatial passage, and even if he had a death mecha defense, it would be in vain. A reaper mech with no power is no different from a pile of hard scrap metal.

Although it was a surprise to find Ling Sha in this world, Yun Feng still wanted to return to his hometown and continue to protect the world he lived in until the next strong man who could compete with the Zerg Mother Emperor appeared.

Because Yun Feng had already begun to wonder if the Zerg Mother Emperor had died directly in this world and returned to the future world, if that was the case, it would undoubtedly be a big gamble!

The Zerg Mother Emperor died in this world in the gambling cloud summit, and she who had already been reborn by then would naturally be able to take the lead, even if Yun Feng was reborn again, she could completely suppress Yun Feng before Yun Feng recovered.

But Yun Feng was betting that he would be able to return to the future world alive, and the rebirth process of thousands of years was enough for Yun Feng to grow to the height that the Zerg Mother Emperor looked up to, and he could even directly destroy and rebuild the law like a consciousness creature!

The dangers that Yun Feng is facing now are nothing more than two, the traitor of the God Realm and the invasion of the Demon Realm, no matter which one is something that Yun Feng can compete with now, at least not before the construction of the War Fortress.

The visit of the elves gave Yun Feng a reminder, since the elves have a sky city, why can't the human race build it? With the current strength of the human race, it shouldn't be a problem to rush out hundreds of sky cities, right?

Although Sky City is not as good as a Star Destroyer, it should not be a problem to stop those weak demons at the time of the invasion of the Demon Realm, while Yunfeng's Star Destroyer needs to be killed one-on-one against those demon powerhouses, which can also make up for the loophole of the insufficient number of Yunfeng warships.

It seems that it is time to make a trip to the Elven Forest to get the blueprints for the construction of the Sky City.

Windsor on the side didn't expect that Yun Feng had already hit their idea on their Sky City, and even wanted to build hundreds of them! You must know that the elven clan only built ten in its heyday.

"The Sky Core has been forged, according to the regulations, not only will I receive a reward, but these materials will also belong to me, and also, due to the special materials in it, this Sky Heart cannot be put into the space equipment, how are you going to bring this Sky Heart back to the Elf Clan?" Yun Feng said, pointing to the cube that was emitting rich energy fluctuations.

Yun Feng's words stunned the two elf girls who were about to cheer, right? It's strange that such a big light bulb is not noticeable on the body! Such a rich energy fluctuation, even if it is not an artifact, it can attract the attention of many people, who knows if there will be some guys who want to make some money?

Thinking of this, Windsor also regretted it, knowing that he would not let Yun Feng add the last process, at least there would not be so much trouble.

But the finished product has already come out, and the remuneration has been paid, and it is too late to regret it, this sky core must be brought back to the elf race!

"You don't have much time, although the defensive enchantment in my laboratory is very solid, but the energy fluctuations of this sky core are about to reach the critical point of the defensive enchantment, if you don't come up with a solution quickly, I can't guarantee that those strong people who sense the sky core will not be greedy. ”

Although Yun Feng said urgently, his expression was very relaxed, and he almost wrote on his face, "Come and ask me! I know how to solve this problem!"

Although the elves are a little stubborn and can't turn their heads, they are not stupid, they can naturally see Yun Feng's expression and tone, but it is still a little difficult to ask them to ask a human. (To be continued.) )
