The steel fortress of the demon race is surrounded by countless large arrays in a spherical area with a diameter of tens of millions of kilometers centered on the fortress and wormhole.

Why is it enclosed in such a large area?

Very simple.

Similar to the military weapons derived from earth technology, the main drug is gunpowder as the driving force, and the further is nuclear weapons. However, the weapons derived from earth technology, such as nuclear weapons, seem to be amazingly powerful, but in fact, they only have a certain lethality to the warriors in the early stage of Shenwu, and from the early stage of Shenwu to the Tianwu level, there is a difference of two levels and twenty great realms, and if you want to cause damage to weapons at this level, you must be more powerful weapons.

Alpha Stars who have reached the sixth level of civilization have powerful weapons of this level, which combine light energy and space energy into one to develop extremely terrifying killing weapons, including things such as planetary-level railguns, which are almost against the sky.

However, the release of high-powered weapons undoubtedly requires more energy, high-powered engines, high-quality crafting materials, and incredible recoil, so the strongest weapons cannot be mounted on relatively small mechs and warplanes.

Even some weapons cannot even be installed on warships, so they can only be used as land-based weapons, and the steel fortress is like a planet.

A large number of incredibly powerful weapons were installed there, some of which were space-level weapons, enough to inflict fatal damage on the powerhouses above the Heavenly Martial Triple Heaven.

But!

This kind of weapon is driven by light energy, and there is one of the biggest advantages of light energy weapons, that is, they are extremely fast - in addition to wormhole crossing and space transfer, this kind of space crossing by abnormal paths, the speed of light is the fastest in conventional speed, even if the Tianwu Sixfold Heavenly Powerhouse flies a hundred times slower than the speed of light, so the strike of light energy weapons is largely an unavoidable attack.

However, there is no such thing as absolute perfection in this world, and while light weapons have many advantages, there is also an unavoidable flaw.

A nuclear warhead launched from one place to another only consumes the propulsion of the launch vehicle during the flight, and the power of the nuclear bomb itself has not changed, but light energy weapons are different, even if the universe is close to a vacuum, the drag in flight is relatively small.

However, in long-distance flights, energy losses are inevitable.

As far as the planetary-level railgun is concerned, if its initial attack power is 10,000, and it hits a target 10,000 miles away, the power is likely to become 5,000, and when it reaches 100,000 miles away, the attack power is likely to be only 2,000 -- the large array 500,000 kilometers away from the steel fortress is located at a distance beyond the reach of the planetary-level railgun whip, which is why the encirclement is so large.

There was a willingness to arrange such a large encirclement, and because of this, two problems were created.

First of all, the larger the encirclement, the more formations need to be arranged, in order to create this formation encirclement, it took Fuxi many years at the beginning, and there were countless ancient powerhouses to cooperate.

As for why the demons did not attack during that period, it was because while Fuxi was building an encirclement, the demons were also creating war fortresses.

At the beginning, this fleet of demons came to the vicinity of the solar system from the distant starry sky, and then discovered that there were advanced life on the earth, and the demons immediately launched a full-scale attack on the earth. Don't you know that although there is no high technology on the earth, it has amazing martial arts power, which directly causes the demons to suffer a fatal blow.

The demons had to retreat to the vicinity of the wormhole in a panic to build an impregnable war fortress and try to be safe first.

In turn, the losses of the human race were even heavier, and they did not dare to attack again, so they could only build a defensive circle around this area, so after the first battle of gods and demons, for a long time, both sides died down and established their own defense lines, which led to the current confrontation situation.

The second problem is that the number of warriors who can participate in this level of warfare is limited after all, and even if the spherical defense line with a diameter of one million kilometers is completed, it is impossible to have enough warriors to be distributed in every place for monitoring - even if hundreds of billions of people are distributed in such a large area, it is obviously insignificant.

In the end, Fu Xi came up with another way to establish a large number of teleportation arrays.

Outside this spherical defense line, an astonishing number of teleportation arrays have been built, and the countless formations that make up the defense line are connected and have monitoring functions, which is similar to an enchantment covering the entire god domain: the entire defense line is completely under monitoring, once a demon appears or is attacked in a certain place, it will be immediately discovered, and the warriors who live in one place will be quickly transferred to any part of the defense line through the teleportation array.

In order to make accurate directional judgments, these teleportation arrays are numbered by the sexagenary branches, and the Boshin teleportation array is one of them.

Qin Yan and the others rushed out of the camp from the courtyard, and went straight to the general teleportation array in the center of the camp at the fastest speed, without the number of the Heavenly Stems and Earthly Branch.

"Golden Dragon! Go ahead of your plan! Qin Yan shouted as he flew.

"Understood!"

The golden dragon that was running out, in the process of flying, the whole body of the golden light burst out, with the golden light flashed, the oily little white face disappeared, replaced by a giant dragon with a body length of more than fifty meters, so that the nearby patrol warriors were startled.

The last to set off was not slow at all, and although he was not a martial artist, he had mastered a high level of technology comparable to that of the Alpha Star.

He sat in a small single spaceship, the flyship has a perfect gravity system and air system inside, ensuring that he will not suffocate, comparable to the gravity on the earth, and the energy shield is even faster than Qin Yan's flight speed.

So, it was obviously the last to set off, and soon came back to catch up next to Qin Yan.

"Qin Yan ......"

Using the communication equipment in the spaceship, he shouted to Qin Yan in the cabin: "Tell me before you act, I am responsible for simulating the stellar ion storm!" ”

Qin Yan wasn't worried about the main light brain system that invaded the demon race, but he created a stellar ion storm...... This should require some kind of large equipment, right?

"Did you bring any equipment?" Qin Yan asked loudly.

"My space box is much more advanced than yours." North's tone was proud.

“……”

The group soon arrived at the teleportation array, in order to cooperate with Qin Yan's actions, Wanyan Lifeng had already sent people to wait, and as soon as they arrived here, the general teleportation array was activated immediately.

With a flash of light and shadow, several people disappeared from the main teleportation array, and there was almost no time interval, in the void hundreds of thousands of miles away, a teleportation array flashed with brilliant brilliance, and a group of people appeared out of thin air.

"This way!"

One of Yan Lifeng's subordinates stood on the edge of the defense line of the large formation, took Qin Yan and them, and flew quickly in a certain direction, and entered a certain formation after about three minutes.

Soon.

Separated by the transparent energy barrier of the large array, Qin Yan saw a fighter plane that he had seen before, and was carrying out a crazy attack on the large array.

There were not only fighters, but also more than twenty mechs.

"Qin Yan, you still have half a pillar of incense left."

The young man who brought Qin Yan over said in a deep voice: "After half a pillar of incense, if this thing has not been destroyed, it will cause damage to the Great Array, and we will destroy it!" ”

"Thank you senior, I understand." Qin Yan nodded.

"Husband, what do you need me to do?" Lou Yuqing asked urgently.

"Look at the excitement."

Qin Yan's words were very simple and clear, he turned his head to look at the golden dragon that had transformed into a body, and said in a deep voice: "I am responsible for killing those mechas, and you are responsible for dealing with the fighters." Remember! The fighter must not be seriously damaged, otherwise North will not be able to invade the system, and even the scientific and technological power we have may be known by the demons! ”

"Don't worry, look at me!" The golden dragon is full of confidence.

"North!" Qin Yan turned his head and shouted.

"It's coming!"

I don't know what technology was used, North actually walked out of the spaceship, and his whole body was shrouded in an energy shield, which played a role similar to a spacesuit, allowing ordinary humans to move naturally in space, but its performance was far stronger than that of a spacesuit.

North quickly opened his space box and quickly took out one cylinder with a diameter of half a meter and a height of one meter, I don't know what it was used for: "Put these things, five hundred meters long on each side, and occupy the intersection point of a cube." ”

Qin Yan, Lou Yuqing, and Ou Tianqi each put the cylinders in a fixed position, and finally the eight cylinders were separated at the corners of the cuboid with a side length of 500 meters. Immediately after, North turned on the instrument on his wrist, quickly called up the small holographic projection screen, and with a few quick presses on it, the eight cylinders immediately scattered a light blue light curtain, forming an isolated space with a side length of five hundred meters.

Qin Yan was in this space, and finally understood the role of this space.

There is gravity, air with the same oxygen content as the earth, and it is simulated as the surface environment of the earth - not only is the movement of the north limited in the vacuum, but some special instruments, without their own energy shields, cannot function normally in space.

Really!

North pressed a few more times on the instrument on his wrist, and the protective shield resembling a spacesuit on his body disappeared, and the next moment the space box was opened again.

A blue halo flashed, and a behemoth appeared out of thin air.

It was a huge, insanely complex machine the size of a bedroom.

With the scientific and technological level of the sixth-level civilization, the volume of the instrument is still large to this extent, and it is conceivable that this is a thing with very strong performance.

"Ready!"

North quickly entered a series of commands on a holographic projection control panel, and immediately something like an exhaust fan behind the instrument spun rapidly at a terrifying speed, and then a channel similar to an exhaust port was propped up above, and dense purple-red electric patterns flashed on the exhaust port.

His finger hung on a certain button and said to Qin Yan, "It's okay!" ”

Qin Yan and Jin Long glanced at each other, their figures flashed to the edge of the big array, and the people sent by Wanyan Lifeng on the other side used their authority to open a portal for them to pass through.

Sou!

The moment the portal opened, Qin Yan and Jin Long rushed out as fast as they could, and almost at the same time as they rushed out of the big array, the snow light illuminated the space, and North's hand hanging on the button pressed hard.
