Chapter 1638 Ultimate Battlefield 1

Xie Qi was really shocked, he stared at the crazy scene before him in a daze.

The legions of the Heavenly Demon World spread out over tens of billions of kilometers, which caused a serious problem: time delay.

Whether it is communication or the speed of light, it will be affected.

It is not that the Heavenly Demon World has not thought about this problem in the past, but it is limited to the practice system of the Heavenly Demon World, and there is no perfect solution. Although there are some means, the delay is still obvious.

In fact, the current communication methods of Dayang Group and Bluestar Group also have delays, but they are still acceptable. This is communication using science and technology.

If it is the quasi-sage and Daluo Jinxian, they still have separate magical communication. However, this kind of communication actually depends on the transformation of the Zhoutian Great World and the Zhoutian Great Formation. Placed here in the Heavenly Demon World, the delay is still quite obvious.

In the face of great nature, even a saint must bow his head. Otherwise, the legendary Holy Emperor would not disappear.

It was here in the Heavenly Demon World, because there was no support from the Zhoutian Great Formation, and coupled with the problem of its own practice system, the delay was even more serious.

It's just that although everyone discovered it in the past, they didn't take it seriously. Because everyone has a delay, it doesn't matter. The Heavenly Demon World has also invaded other worlds, and it's the same. Even some worlds, such as the current Gaia world, are not as good as the sky demon world.

Therefore, on the issue of communication delay, the Sky Demon World "continued" like this. These years are not without improvements, but with limited effect. In the past few years, because of some knowledge of cultivation, he has made some progress.

But no matter how great the progress is, the delay of tens of billions of kilometers is still a bit severe.

Not to mention that the current space is disturbed, making it impossible to move faster than the speed of light. Even if the order has passed, there is not enough time to transfer.

Therefore, when Xieqian discovered the rail gun, in fact, the front of the Sky Demon Army had already suffered the fourth wave of attack; the fifth wave of attack had also arrived.

When Xieqian finally reacted, ordered the transfer, and the information was transmitted to the front, the seventh wave of railguns had already mopped up more than half.

When the Sky Demon Corps finally responded and began to move, the 12th wave of railguns had already arrived.

Fortunately, the demon saints, and the king-level monsters reacted quickly, and most of the masters of the sky monsters escaped the concentrated fire of the rail gun. Even if there is a little attack, it doesn't matter.

However, a large number of king-level (Golden Immortals), especially Xiaowang-level (Huanxu) and the sky monsters of the lower realms, as well as a large number of starry sky behemoths, suffered disaster.

A total of 12 waves of railguns in the focused fire state swept across like a comb, and the entire Sky Demon Army was directly opened 12 times.

Behind, there are more than 80 attacks.

Fortunately, the problem of low hit rate in the void is the same for the Blue Star Group. Most of the railguns missed anything and just flew by. But there are still a large number of rail guns hitting the target and causing unimaginable damage.

Previously, the thinking of the Blue Star Group was: hinder the opponent's progress and buy time; the longer the time is delayed, the more beneficial it is to the Blue Star Group. And in the process of delaying time, 'nibble' the legion of the sky demon world.

Only when there is enough time can the background of science and technology and industry be fully exploded, and a better war of attrition can be carried out.

But because of the sudden eruption from the Sky Demon World, to be precise, the bloody thunder attack of Qishan Demon Saint was too powerful, forcing the Blue Star Group to make changes.

This change is a strong focus.

After all, the Sky Demon World suffered a big loss due to lack of experience.

It is also because the Blue Star Group is so ruthless that they would rather sacrifice the battleship to complete the fire. And Qishan Yaosheng is also busy accumulating credit, and his excitement is a bit too much-how about five billion warships and more than 200,000 Earth Turtles transformed by the enemy, if they can all be wiped out, how much credit is that?

The result is that Qishan Yaosheng's contribution is enough, but the other sky demons have suffered. Even Qishan Yaosheng's own Thunder Domain was hit by two waves of railgun attacks, and the loss was not small.

After hundreds of concentrated fire attacks, the Blue Star Group's warships and Terra Turtles were running out, and they began to retreat.

On the other side, after dodging more than a dozen waves of concentrated fire attacks, the demon saint Xie Chan counted the losses. In this wave of head-to-head 'collision consumption', the Sky Demon World also paid a huge price.

After counting the losses, Xieqian breathed a sigh of relief. Although the loss was not small, because of the slow speed of the rail gun, only a few king-level monsters were injured, and even the king-level monsters did not lose much. Even the Xiaowang class and some starry sky behemoths lost a lot, but they were less than 3% of the entire legion.

Overall, it is acceptable. The subsequent attack was blocked by Qishan and Thunder Domain.

After a little discussion, the Celestial Demons moved on. But this time be more careful. They learned to detour, learn to walk in curves, learned to send teams to explore, and learned to search for the enemy's detectors...

If you have suffered, you will naturally learn to be good. Because of the detour and avoiding the interference of a large number of rail guns launched in advance, the forward speed is actually much faster.

Although there were several disturbances along the way, it still approached a distance of 400 light-years in less than five days.

One-fifth of the 500 light-year strategic depth that the Blue Star Group had divided in advance disappeared in the blink of an eye.

It wasn't until here that the Blue Star Group stopped the opponent again. In order to intercept the Sky Demon's legion here, the Blue Star Group made a 'bureau' with almost a hundred light-years ahead.

As the sky demons were advancing, they were disturbed without knowing it. Coupled with the increasing number of detection equipment of the Blue Star Group, it is becoming more and more difficult to hide the traces of the sky monsters.

It's just that the sky demons attacked extremely violently this time. Seeing that the Blue Star Group actually mobilized almost two billion spaceships, Qishan Yaosheng directly activated the new Thunder field. The rest of the demon saints, except Xie Chan, also made moves one after another.

Among them is a demon saint: a bird head and a human body with three pairs of phoenix wings, who can control flames. The flames controlled by this demon saint are not ordinary flames, but... stellar ones!

In just a few breaths, the figure of this demon saint skyrocketed to a million kilometers. Flapping its wings towards a star, the flames of the entire star were blown away by a layer.

The fiery stellar atmosphere, or rather the high-temperature plasma poured into the void, sweeping across hundreds of millions of kilometers. Under the wave after wave of flames, more than half of the battleships of the Blue Star Group were blown away by the solar wind in an instant.

The super high temperature caused serious damage to the battleship, loss of power or lack of power, and the sky monsters caught up with it and smashed it.

The Blue Star Group is setting up a game, and the sky monsters are also setting up a game!

In this confrontation, it was clear that the sky demon had the upper hand.

And the demon sage with bird head and human body and six wings, after a 'blow', weakly lay behind Xieqin, and began to frantically devour the plundered cultivators-this time the temporary mobilization of more than two billion warships was not without Human-machine.

After that, without waiting for the Blue Star Group to react, the mighty Sky Demon Legion crossed the interception line, and then rushed forward frantically, approaching a range of less than 200 light-years in one breath!

The strategic depth of 500 light-years prepared by the Blue Star Group in advance lost 300 light-years in just ten days!

The situation is tense.

Sure enough, the plan couldn't keep pace with the changes.

What is even more tense is that the outermost detectors discovered that there are legions of all sizes gathering from all directions in the Heavenly Demon World. The reinforcements of the Sky Demon Legion are arriving.

"It seems that the Sky Demon World is fully prepared this time. It is going to destroy us in one go." In the command center, Zhang Hao looked at the projection ahead and said quietly.

The projection in front is hundreds of meters long, showing the starry sky with a radius of thousands of light years. However, due to the uneven distribution of detectors and the vastness of the starry sky, there is not much information displayed here.

But it can still be seen that outside the range of thousands of light years, many reinforcements from the world of sky monsters have appeared one after another, and there are many big monsters at the level of heavenly kings among them.

Among these reinforcements, the figure of the demon saint and the energy response have not been found for the time being, but it does not mean that there is no such thing. After all, the number of detectors and the scope of detection are limited after all.

The situation is actually a bit bad. But Zhang Hao was surprisingly calm.

Dugu Junjie frowned and looked at the star map, thinking about the strategy. But for a while, I was a little helpless. The sky demons have learned their lesson, and the Blue Star Group wants to wage a war of attrition head-on, but the other side has started guerrilla tactics.

Although the Blue Star Group is very powerful, more than 30 billion warships have been dispatched from the entire Blue Star Group, and 13 billion warships have already arrived temporarily. In the starry sky, I can't afford a single wave.

The starry sky is too vast.

And the sky monsters, after the initial recklessness, also made full use of the advantage of active attack, and even circled and circled around the gate of the world.

In the dullness, Zhang Hao spoke again: "I think of a way now, to do an extraordinary method at an extraordinary time! Let's see if it works.

That is to completely abandon all the previous arrangements, shrink all the power to the gate of the world and the blue flag star cluster, and turn this place into an ultimate battlefield! "
