This palace is still so upright, but on the other side of the glory, this palace is very quiet.

Although there are sound waves all around here, don't think that sound waves have sounds, these sound waves attack and use ultrasound waves and infrasound.

The so-called sound waves, in fact, the sound waves of the sound that every mage can hear have a certain frequency.

Only when the sound wave is at the frequency that the mages can hear, the mages can hear the sound, and the frequency of the sound wave higher than the sound wave that the mages can hear is called ultrasound, and vice versa is called infrasound.

Such sound waves are not audible to mages, but they are extremely penetrating and aggressive.

Su Ze used his spiritual power to isolate himself from these sound waves in the outside world, but Su Ze could feel the terrifying energy coming out of these sound waves, but Su Ze couldn't hear any sound now, everything around him was too quiet, and the silence made Su Ze a little scared.

"Since there is energy emitting from here, the center of the emitting energy should be the inside of this palace. ”

Looking at the majestic and gorgeous palace in front of him, Su Ze approached it and said slowly.

The interior of the original gorgeous palace is now already a matter of fact, because the demon clan is entrenched in it, the alliance army of the Yunmeng Federation and the Northern Lion Federation has baptized this piece of the imperial city, Su Ze came to the place where he was directly controlled by the holy dragon eight years ago and forcibly exterminated a ninth-order cultivator.

The gardens around the original have long been wiped out at this moment, and all that remains is the stump of a place.

Some of the surrounding pavilions are also crumbling, and some even have only a few bricks left in place, which makes it difficult to imagine what they looked like.

If Su Ze did not enter the interior of this piece of palace, what this piece of the capital of the Broken Shell Federation brought to Su Ze was a very shocking majestic beauty.

But now that Su Ze has entered this piece of palace, looking at the surrounding scenery makes Su Ze feel a poignant beauty.

The one that Su Ze entered behind him to accommodate Su Ze to enter this space, the small passage from this defense facility, was also quietly closed at some point.

The reason why only one person can be allowed here is not because of the problem of this area, but because of the surrounding defenses, the various procedures originally set up are that only one person can be allowed to enter.

Su Ze didn't know why, this defense facility would have such a headache, but it seemed that in order to build a defense facility, those staff had to gradually improve a defense facility on this one loophole.

In other words, it seems that this defense facility can only accommodate one person to enter, which is the basis for the construction of the entire defense facility, if you want to change a defense facility to accommodate only one person at most, then the entire defense facility must be dismantled and rebuilt.

But all the defense facilities around here are made according to the engineering drawings of those demons, and the ingenuity of those design drawings is also surprising to all the engineers of the empire.

However, no Empire engineer can draw inferences from it, and can only use the drawings designed by these demon engineers to build such a device that can emit sound waves to affect and distort space and time.

Otherwise, perhaps all empires would not be able to build even this piece of equipment in front of them.

Su Ze could only sigh slightly, the strength of the demon race is really too strong, these design drawings are simply difficult to figure out, no wonder they can invade other planes infinitely.

However, even if these technologies of the demon race are far stronger than those on the planet where Su Ze is located, in the face of the invasion of the demon plane by Su Ze, it is impossible for everyone on this planet to look at it in vain.

Everyone must work hard to fight and fight.

"There doesn't seem to be anything around except sound waves, but why can you feel such terrible energy fluctuations when you're outside?"

Su Ze walked in this palace, but he didn't feel any kind of movement around him.

In this piece of heaven and earth, except for the sound waves that were constantly emitted towards a piece of space by the surrounding defense facilities, there was no other fluctuation that Su Ze could feel.

Su Ze's spiritual power has already reached the realm of the Sage, so all fluctuations in this world are logically impossible to escape Su Ze's detection.

Since Su Ze is confirming himself here, he can't feel any energy fluctuations at all, so maybe there are really no other energy fluctuations here.

For such a piece of palace, in fact, Su Ze didn't know much about it, after all, when Su Ze came to this piece of palace before, he was knocked out just outside these palaces, and he couldn't really enter the deepest part of this palace at all.

So now after eight years, even those mages who have entered this piece of palace before may have almost forgotten the structure of this piece of palace, and Su Ze wants to start slowly getting familiar with this piece of yellow work now.

However, Su Ze was not too flustered, so he walked slowly, and when he saw the pavilion that had not collapsed in this piece of palace, he went in to check one or two.

Slowly, Su Ze surrounded this piece of palace and walked to the most central part of this piece of palace.

Su Ze is going around this piece of palace, so this palace in the most central part of this piece of palace is equivalent to the deepest part of this piece of palace that Su Ze thinks.

This is the place where the emperor was in the early days.

Hundreds of steps of stairs have been extended from Su Ze's feet to the palace not far in front of Su Ze, and each step of the stairs is presented with a very picturesque dragon flying phoenix dance, and there is no abnormality in this piece of palace that Su Ze explored before, so the only thing that may exist is the palace in front of Su Ze.

The staircase in front of Su Ze is something that only the king of a country can walk.

But now that this empire has long since perished, Su Ze hesitated, this is what everyone dares not do-

strode directly onto the stairs in front of him, a ladder that only the emperor of a country can walk.

"It's a little bit of a hindrance!"

Stepping on this ladder, Su Ze couldn't help but complain.

Soon, Su Ze strode towards the palace in front of him.

In such a palace of the early emperor, although it was very exquisite, it was small, and Su Ze estimated that he would not notice anything abnormal in it.

Maybe the energy fluctuations felt outside this one defense facility are just something wrong with this one defense facility.

And the paddling staff didn't even seriously test a single instrument.

Su Ze came to the front of this palace.

This palace that looked empty, but it was a very powerful impact that Su Ze felt head-on.

If it weren't for the fact that Su Ze had been guarding against the outside world by controlling his mental power, then Su Ze might have been directly forced back by such an impact as he was facing.

Su Ze turned his head slightly and looked at the long staircase behind him, and he couldn't imagine how painful it would be if he was really repelled by such an impact, then it would hurt to fall down such a long staircase.

But why did the empty palace in front of him erupt with such a strong impact? This made Su Ze slightly puzzled.

It stands to reason that these impacts must have an energy source, but Su Ze looked at it at a glance, there was nothing in this palace at all, and the palace was completely empty, not even the most conventional dragon chairs, beams and pillars.

It is simply impossible to have any energy source in a place that Su Ze can't see.

And from the impact Su Ze received before, the energy source that Su Ze could analyze and emit an impact on himself must be directly in front of Su Ze.

However, Su Ze was just in front of him, and he could face the deepest part of a palace, with an unobstructed view, and it was impossible for anything to exist, and it was still impossible for Su Ze to see.

"Isn't there something invisible in this?

Su Ze smiled slightly, this is the time when he slowly stepped into this palace again.

This time Su Ze was well prepared, but the previous impact did not hit again, it seemed that such an impact also realized that Su Ze had already had his own means to resist the impact, so this was not bursting out of his own strength, as if he wanted to deliberately hide his breath.

In this regard, Su Ze also sighed secretly, I have to say that if that impact has his own thoughts, then he must be very smart.

However, Su Ze also believed that with the spiritual power of his Sage Realm, he would definitely be able to find out the impact of plotting against himself.

Walking into this piece of palace circumference, countless rebounding sound waves came from all directions, these sound waves were intertwined, large and small, constantly rebounding and rebounding, which made Su Ze feel dizzy.

This made Su Ze couldn't help but guess, maybe the impact that people felt on the outside of this defense facility was the sound waves in the palace in front of them, through various rebounds and some opportunities, thus forming a wave of energy source that fluctuated outward.

This is the formation of an impact like external fluctuations, which is perceived by outsiders, and is what will make everyone think that there is another invasion of alien civilizations here.

"It all feels like it's all a false alarm!"

Su Ze was convinced of his guess, but he was also very surprised that the Demon Clan's Hearing Demon Clan had not returned to Su Ze's planet for eight years.

With the nature of the demon race, it should be impossible, just let his millions of troops be buried on the planet where Su Ze is located, since they have suffered losses on this planet, they must be willing to repay the planet where Su Ze is located, and this plane at any cost.

And with the very powerful technology of those demons, it is not impossible to completely fight against the mages of the planet where Su Ze is located.

Since those demons have found the sword spirit of a large nameless sword, and successfully used the power of the nameless sword sword spirit to open up a space-time tunnel again, then they can change the end point of the space-time tunnel they opened to another place!

In this case, perhaps, in a sense, the defense facilities that the people of this planet have worked so hard to gradually develop will have no effect.

But why haven't the demons taken any action for eight years, could it be that they are planning some kind of terrible conspiracy again, and when the time comes, they will directly let the people on this planet react to you at all?

In eight years, even if those demons locate in the plane where Su Ze's planet is located, they should have already searched for the coordinates of the planet where Su Ze is located, and in eight years, even if those demons don't use the power of the nameless sword spirit, they can successfully repair the original space-time tunnel that was blown up by Ling Xue and his party many times.

Since some people are selected to estimate that if those demons want to restore their original space-time tunnel, it will only take a year, then for the demons who know more about that space-time tunnel, it should not take more than a year.

But now, eight years have passed.

"Could it be that those demons took the initiative to give up on our planet? Then there are still some powerful words, what I'm afraid of is that those demons chose other planets to attack, but we don't know at all!"

Su Ze was perceiving the sound waves around him through his spiritual power, and at the same time, he couldn't help but guess.

However, when Su Ze slowly approached the center of a palace, he suddenly found that in the center of this palace, there really seemed to be an invisible energy source, and the existence of such an energy source was not formed by the rebound and aggregation of these sound waves around him, because the book could feel that the breath emitted from the most central energy source of this palace was far more powerful than the original sound waves.

In other words, some of the fluctuations emanating from this energy source discovered by Su Ze were more powerful than the original power of these sound waves around them.

Sound waves are a kind of energy, and the energy will inevitably weaken after reflection.

But the energy source that the writer feels at the moment is indeed more powerful than the energy that these sound waves bounce back and before, so this completely shows that the energy source that Su Ze discovered is not the product of those sound waves after gathering at all.

But why did such a terrifying source of energy suddenly appear in the midst of this?

And the breath emitted by an energy source is very terrifying, logically speaking, this terrible breath should be able to permeate the entire castle, but this energy source is perfectly controlled by its various information in this palace, which means that this energy source may have its own unique structure.

Perhaps in this energy source, through some means, his own breath was directly emitted to the outside world of this defense facility, but he successfully suppressed the spread of his own breath inside this defense facility.

In Su Ze's mind, unless it was an individual with self-awareness, there was no machine that could do such a magical act.

Su Ze slowly confirmed the location of the energy source he had discovered through his spiritual power, and this was the one that slowly approached that energy source.

Although that energy source is completely transparent and invisible compared to Su Ze, in Su Ze's perception, it is possible to perfectly determine the specific shape of this energy source.

This energy source is a crystal similar to a diamond, Su Ze's spiritual power cannot penetrate this energy source, maybe the origin of this energy source is too powerful, even if Su Ze's spiritual power has reached the Sage Realm, it is difficult to penetrate this energy source, and this energy source is completely explored.

Or maybe the energy source that Su Ze showed was a solid one in itself, so that it had a very strong external defense power, making it difficult for Su Ze's spiritual power to penetrate.

But what is this energy source, Su Ze doesn't dare to touch it with his hands, what if he directly crushes Su Ze's hand?

Therefore, Su Ze could only rely on his spiritual power to confirm the shape of an energy source, but the essence of this energy source was still to be determined.

Su Ze cautiously bypassed this energy source, and then found that in this palace, except for this energy, there was no other place with strong energy fluctuations, so all the abnormalities in this defense facility that everyone in the outside world noticed may be formed because of the existence of this energy source that Su Ze is now perceiving.

Now it is necessary to confirm through some of your own means what kind of structure and substance there are in this energy source.

First of all, Su Ze wanted to determine whether this energy source was a solid, a liquid, or a gas.

Generally speaking, though, none of these energy aggregates will be liquids.

Su Ze wants to determine what kind of physique this energy source is, so the simplest TV, let Su Ze directly cast a spell, to see if his spell can penetrate this energy source, if it can penetrate this energy source, then maybe this energy source is gas, if Su Ze's spell is directly bombarded by this energy source, and then it is shattered, then this energy source is solid.

It's just that this energy source is either solid or gas, but it can perfectly hide its own figure, which makes Su Ze feel magical.

A small wind blade formed in front of Su Ze's body, and with Su Ze's current mastery of all the elements, it was still very simple for Su Ze to cast a complete elemental spell.

However, this is limited to Su Ze's application of various elements, for those more powerful spells, it is still necessary for Su Ze to slowly learn other new spells and understand the coordination and circulation between various elements.

The wind blade formed in front of Su Ze was extremely strong, and it had a penetrating power far beyond ordinary spells.

After all, the energy source that Su Ze was facing in front of him had very strong energy fluctuations, and if the energy fluctuations of the spell released by Su Ze were not too strong, then it would be difficult for Su Ze to let his spell pass through this energy source at all.

After the wind blade in front of Su Ze was completely formed, Su Ze directly let his blade slash forward.

The wind blade, which had extremely penetrating power, was directly released forward by Su Ze in this way, and it quickly blasted towards this energy source in front of him.

But then a fantastical scene happened directly.

I saw that when the wind blade released by Su Ze was about to touch the source of the energy source that Su Ze perceived, the surrounding counties and cities suddenly seemed to stand still in time, and the wind blade released by Su Ze stopped in place in an instant, and the energy contained in it also completely lost its fluctuations, and the surrounding sound waves that were originally mixed with each other and chaotic, and the bouncing sound waves also stopped at this moment.

At this time, in this piece of palace, compared to Su Ze, it was completely quiet, without any sound or any breath fluctuations.

If it weren't for Su Ze still being able to hear his heartbeat, Su Ze really thought that his perception would be damaged in an instant.

But the surroundings were so quiet that Su Ze could hear his heartbeat perfectly, which was really terrifying and magical.

Su Ze was stunned by the scene that happened in front of him, and he reacted suddenly after being stunned in place for a long time.

Walking slowly, moving his body, Su Ze found that his body could still move flexibly, and Su Ze was also able to find his own body, these spiritual powers were also able to circulate and operate perfectly, and the book's heart mission was not oppressed in any way, Su Ze did not feel any abnormal situation in his whole person now, just like Su Ze standing in an area without any strange scenes.

But what was this scene that Su Ze saw in front of him, the wind blade that Su Ze emanated from stayed in place like this, and Xu Zhong still didn't have any aura fluctuating.
