April 6, 183 in the New Western Calendar, Tian~Chao Western Wasteland, Iron Gate Research Institute, three floors underground.

"Fortunately, this commission has lifted all the restrictions, otherwise it would be really difficult to do."

[Personal Request: Hindering the Fight against the Native Species]

[Commissioned content: For the current earth, the existence of native species is extremely dangerous.] We have to keep it under control! First of all, you need to prevent the native species from entering and exiting at will in the sky ~ towards the west. Then, we need you to annihilate all the native species that appear in public at the first time. Until we have our hands free to solve these troublesome historical legacies! 】

[Entrustment reward: 1000 points for base, 1 point for soldier, 10 points for elite, 100 points for captain, 1000 points for ace]

[Entrustment price: Until Xuefeng and others admit it in front of others, otherwise they must keep relevant secrets, and at the same time give all their assistance to Xuefeng's actions against the native species]

[Authorization Limit: As long as you are not exposed to outsiders, all abilities can be used at will]

At this time, in a space on the third basement floor covering an area of more than 1,000 square meters, the ground was already engraved with countless runes and arrays.

The entire array had actually been activated, and the mysterious silver-white brilliance flowed along with the lines on the array, and one rune stick after another exuded its own brilliance, floating quietly in mid-air.

"Alright, that's the last node." Yukikaze built an iron rod inscribed with runes and gently placed a section of it on the ground.

Then, the runes on this rune stick lit up one after another, and after all the runes were activated, Yukikaze let go of his hand. When this rune rod was like its predecessor, floating in the air, the snow wind had already retreated to the outside of the formation.

The next moment, the runes on all the rune sticks began to flicker, as if confirming something, and as if they were echoing each other.

Countless radiances bloomed in an instant, and these rune rods changed their positions in the blink of an eye, and one after another brilliance connected the rune rods. But that's not the end, or rather, it's just the beginning. Because the rune stick had begun to follow some kind of inexplicable trajectory at this time, moving in mid-air on the formation map.

"Whew, is this what the spatial structure of this area looks like?" After the formation was completely and smoothly running, the snow wind floated directly above the entire formation, overlooking the formation that was running under his feet.

"So, let's get to work." When Yukikaze was about to start doing something, he suddenly remembered something, and took out a small piece of biological tissue of unknown composition from his personal space.

A temporary floating alchemy array, above this piece of biological tissue, was randomly engraved in mid-air by the snow wind.

I have to say that after learning the basic alchemy of the underworld, the general basic runes and the rune magic "position", Xuefeng's alchemy, rune and magic circles have been raised to a fairly powerful level.

Of course, Xuefeng's own super-nova mystical side talent also contributed to it.

In the dazzling brilliance, this piece of biological tissue is gradually transformed into a crystalline substance.

Now this piece of material in Xuefeng's hand is officially known as unilateral state synchronization substance. Through this piece of matter, you can intuitively understand the real-time state of the organism or other existence that you are connected to through the medium of this matter.

As for who this original biological tissue belonged to, I believe everyone has a little bit of an eyebrow, so I won't spoil it here.

Then this crystalline substance, which looked good in color and brilliance, was neatly sealed in a piece of transparent crystal by the snow wind.

Although it is unilateral synchronization, some beings with strong spiritual power or strong enough strength can still perceive this substance. So, at this time, it was the turn of the crystal used as a secondary partition to appear.

In just a few moments, the crystal surface wrapped in crystalline matter was inscribed with countless runes by Snow Wind and thrown into the slowly moving magic circle below.

At the same time as it fell, the inscription on the crystal had already started to move, and then adjusted the direction of its fall in mid-air. When it finally landed in the circle, the crystal had already arrived at its rightful place, and along with the other rune rods, it began to move in some inexplicable trajectory.

"I hope I'm doing something superfluous. However, there is nothing wrong with being careful. ”

Xue Feng no longer looked at the array under his feet, but came to the center of the sky above the circle. With his eyes closed and his hands clasped together, Xue Feng's spiritual power was all thrown into this huge magic circle on the ground.

With the movement of the snow wind, the operation of the circle stopped for a moment, and then when it was running again, it was no longer the original trajectory, but a different trajectory.

Even ordinary people come here, although there is no way to know for sure, but they can clearly understand that this second trajectory is more than ten times more complicated than the first!

"In this way, there should be no random native species in this area." Xue Feng lowered his hands and flew in the direction of the underground exit, "Well, although this is only a palliative solution, but in ten years? It's not necessarily true who hits whom. ”

That's right, Yukikaze didn't use methods such as blocking, filling, etc., but only added a dense space to this area. Without decryption, the other party will not be able to come to this area through any spatial transfer, and the fate of forced transfer is to be randomly thrown elsewhere.

If the other party really has the existence of a proficient space or formation, then it is very likely that the lock on the snow wind will be lifted. But Xuefeng bet that the other party does not have this kind of talent, or even if there is, he will not use it.

After all, it only takes about ten years of quiet waiting, and this space will naturally form a spatial passage that is close to permanence. For the native species that have been waiting from ancient times to the present, ten years is really just a flick of a finger.

Although as long as this space continues to weaken, then the so-called encryption is a joke. But in fact, other known methods are also palliative, not curative, for the space in this area.

If the continuous weakening of the ontology of space is not fundamentally solved, then there is no need to think of any way to cure the root cause, which is simply impossible.

In the name of the Ilona Continent, which has been fighting a holy war for tens of millions of years with two forces located in two dimensions!

With the departure of the snow wind, the vast basement returned to silence again, only the silver-white brilliance of the magic circle on the ground, the rune rod that was running silently in mid-air, and one of the inscription crystals sealed with crystalline matter.

A few minutes later, Xue Feng returned to his office, which is the director's office, and began some of his work for the day, such as reading and reviewing various news, documents, applications, novels, etc...... Something else seems to be mixed in with it?

Hawkers, don't care, don't care, anyway, it has nothing to do with our story.

Kindness? Why did Yukikaze suddenly rise up to open a research institute, you ask? And a research institute dedicated to the study of the Overwatch Dragon Tech Tree? Instead of finding a place to nest like the previous plane?

First of all, it should be noted that Xuefeng's actions in the plane, except for the energy, abilities, props, and weapons used, are limited, and other actions are completely arbitrary.

As long as Xue Feng is willing, it doesn't matter at all that he just uses his wisdom and takes a moment to directly turn the whole world upside down.

The existence of Hades is mysterious.

But this is only referring to the Dragons of the Watch, and the House of the Dragons of the Watch, from the very beginning, was itself a window to the outside world. Nature is under the limits, all kinds of arbitrary.

As for why the last plane was directly nested in the home that was bought from the beginning, it was because of the [plane commission: I am a cheater!] ] for the sake of it.

The best way not to be noticed by anyone is to stay at home. As a result, Xuefeng, who has a strong house attribute in itself, is completely unaffordable.

Naturally, opening a research institute now is not a sudden idea, but a plan that Yukikaze has been expecting for a long time, and this time it just coincides with the meeting. And why is the highest level of secrecy adopted? This is purely because of Yukikaze's understanding of this timing, and in order to avoid countless troubles now and in the future.

As the tech tree continues to climb, sooner or later, Yukikaze will have to break away from the humble research room like a handicraft workshop and establish a real professional research institute.

And as the level of the target technology continues to rise, the price of the other party will become higher and higher, and the content will become more and more profound.

What's more, even if Xuefeng is tackling the basic technology now, the volume of its trial machine has long exceeded the size of a research laboratory, and professional production equipment and assembly equipment must be used. Moreover, the Ace Branch of the Fu Guide Civilization War Technology Tree that Xue Feng chose as the "strongest black technology tree" alone surpassed the restrictions of the Sword Art Online Plane on Xue Feng and others.

What is the initial restriction of the plane on Xue Feng and the others?

Quite simply, it is determined by the limits reached by the strongest civilization in the main area where Yukikaze is active.

Although it is possible to constantly touch its own limitations by constantly completing plane delegations. However, Yukikaze and others

So, in this OG world where black technology is flying all over the world, Xuefeng can finally research and manufacture all kinds of dangerous items at will in the outside world!

As for why this institute is called the Iron Gate, not the Overwatch Dragon?

Quite simply, because of a commission that Yukikaze received.
