According to the information provided by Saro, the internal structure of the cave can be roughly regarded as a ring-shaped maze. There are nine floors inside and outside of the maze, and the two floors in the middle belong to the core area. Although he was determined to explore the situation inside clearly, it was a pity that the shadow clones were all very unsatisfied and died on the road to the second floor.

At present, they are located on the eighth floor of the maze. When Wang Yanyuan broke through these walls with a black fist with hatred, the scene they saw was not exactly the same as what Saro described before, but it was not much different. Because after entering the eighth floor of the maze, they did not see the enemy, nor did they see the ferocious and terrifying female ghost. But some dark blue flames leaped in the distance and slowly floated towards them.

These dark blue fires are like the "ghost fire" burning on the grave, or "phosphorus fire". If these flames are really "phosphorus fire", it is not worth worrying, but Cao Nian and others will certainly not take it for granted that the mechanisms designed by the other party are used to scare people.

"Spiritual Fire?" Chen Ming snapped his fingers, and a wisp of cold air shot towards the ghost fires.

In the world of reincarnation, ordinary flames, that is, the flame light released by the violent redox reaction of combustible substances after reaching the ignition point, are usually called "extinguished fire", because although the temperature of these flames can reach thousands of degrees, they can ultimately be explained by scientific laws in the real world. In contrast, some flames cannot be explained clearly by scientific laws. For example, the "fire escape" released by chakra has no combustible substances, but they can release flames of more than ten meters long out of thin air. This must be scientifically classified as "unsolved mystery".

And usually.

These flames are called "spiritual fire". Although the temperature of spiritual fire may not be higher than that of extinct fire, it always means more dangerous because it can be generated out of thin air and makes people unable to defend against it. At present, these flames floating in the air obviously belong to the kind of rootless spontaneous ignition spiritual fire. Therefore, the Shura team is particularly careful when dealing with these things.

Everyone is a little wary of things that cannot be explained by common sense.

"This thing is very hot, and several of my clones were burned to ashes by this thing." Saro said with a solemn expression.

While talking.

The cold air released by Chen Ming had swept across the flame.

The dark blue flame was wrapped in the ultra-low temperature cold air, and it did not mean to dissipate. Instead, it competed with the strong cold air.

boom--

The flames wrapped in the cold air became even more vigorous. These flames seemed to have a real soul, and were provoked by the other party, and naturally had a little emotion. They began to burn violently, fighting the cold air forever. The collision between fire and ice suddenly made a large amount of fog pop up in the entire passage.

Chen Ming frowned, "So strange!"

Chen Qi said, "Can you handle it?"

Chen Ming nodded, "Don't worry, sister."

After saying that.

The realm of absolute zero is released.

Everything around me was frozen instantly.

The flames that had originally burned themselves wildly were extinguished.

only.

Although the flames were extinguished, metal spheres fell from the air and fell to the ground and made crackling sounds, like a rain of steel bullets. Looking at the beads falling on the ground, everyone looked at each other. Saro looked suspicious, wondering if he had read it wrong.

What's this?

Sakura picked up the small steel balls on the ground and put them in her hand to look carefully. "It seems to be a miniature flame emitter, but the shape is very strange."

As she said that, Sakura placed these small steel beads by her nose and sniffed them, "It might be some kind of high-energy compressed gas."

Chen Qi looked at it, "It seems that this thing is not a ghost fire, or spiritual fire, it is just some high-tech natural flames."

Chen Ming said, "No wonder the temperature is so high, so that's it! But such a small ball can actually release such a strong flame, which is amazing. Compared to the treasure that the other party spent a lot of money to get!"

If it weren't for Chen Ming, who was born to restrain flames in the team, they might not have been able to live to this day without any harm. Although natural flames are ordinary and the principle is very simple, they cannot be underestimated. They think that when some substances are burning, the temperature can easily reach thousands or even thousands of degrees, and even metals can be instantly vaporized.

Saro said, "It's just my clone who died too quickly, otherwise I wouldn't have seen these flames as ghost fires. So, as 'radish' said before, everything here is not a ghost, but someone uses these high-tech things to make a mystery?"

"It's probably true." Wang Yanyuan stood by the wall, ready to smash the second wall. The man holding the big knife also took out his huge weapon again, preparing to make a knife towards the wall after Wang Yanyuan took action.

"Isn't it good for us to go on a normal road? We have to smash the wall so violently?" Zhang Yang murmured in a low voice, "We are not from the demolition office."

"Because this is faster, if you move forward according to the map, you should waste a lot of time." Cao Nian said, "This is like a plug-in in the game, which can save us a lot of time."

"But-I never cheat!" Zhang Yang was serious, "I have never used perspective, locking, and self-sighting! Do you know that a gamer should have the most basic game ethics and plug-ins that destroy the balance of the game. I firmly resist it, like me-"

"Enough is enough, I know, can you shut up?!"

"Of course... By the way, you said that this fire-breathing little bead is so powerful. Should we pick up two of them secretly? It can also be used as a killer weapon!" Zhang Yang asked.

"First of all, the things here are from the other party, and we can't use them even if we pick them up. Secondly, after the battle, everything will be 'zeroed' and we can't keep anything. Even if we pick them up and put them in the space pocket, these things will disappear after returning to our world."

"Oh, there's something like this!"

“···”

Boom-

The two of the Shura team struggled for about half a minute, and the wall shattered. One by one, one after another, entered the seventh floor of the ring maze from the second gap.

Like the previous floor, there is still no defense here.

"Hey, there is no one? Is the people in this fortress dead in Chengdu?" Zhang Yang said.

"The tranquility before the storm," Cao Nian said, "It's better to be careful."

The passage is more than ten meters wide, and there are many "forks" in the middle to mislead people. If it weren't for the map provided by Saro, they wouldn't even know that the next layer of passage was behind the wall. Just as they were moving slowly, there was a noisy sound from the passage, like countless creatures flapping their wings. The sound was amplified in a nearly closed environment, which seemed extremely clear and even a little too noisy.

"What's the matter this time?" Zhang Yang's hearing is much better than that of ordinary people, so he is the most unbearable for this high decibel sound. He covered his head with some pain, "It sounds like a bat!"

"If it's a bat, that's great, I'm afraid it's not that simple." Cao Nian said.

Indeed, if it were the kind of vampire bats they encountered in the famine world, it seems to be a piece of cake. After all, there are guys like Chen Ming here, and it would be too easy for him to deal with such groups of creatures. In fact, even Cao Nian, facing the attack of a large group of bats, it would not be difficult to kill all the monsters, not to mention that he could retreat without losing all his body.

but--

Cao Nian's words once again worked.

Apart from the violent high decibel noise, no creatures appeared around. The sound became louder and louder, and sound waves of different frequencies were mixed in, seriously interfering with everyone's audio-visual. Many reincarnators began to stagger when walking, obviously tortured by this sound. Cao Nian looked at Chen Lang and found that this guy was already in a daze, and there was even blood flowing out of his ears and nostrils!

"Chen Lang, are you okay?!" Zhang Yang keenly smelled the blood. He quickly supported Chen Lang who was standing unsteadily, "Why are you vomiting blood?! Could someone have attacked us?!"

When people around him heard Zhang Yang shouting, they realized that it was not only Chen Lang, but also several people showed the same condition as him, and the blood flowed from their mouths.

Is this too weird?!

Although this sound is harsh, it is not as terrifying as it is.

It can actually cause such great damage to people invisibly.

"It's a sound wave attack!" Someone in the Shura team finally realized what was going on. "If the sound waves emitted resonate with some organs in our body, then they can kill people invisibly, and we will die due to internal bleeding!"

With the change of sound wave frequency and the gradual increase of decibels, there were more or less some strange things happening to everyone.

Even some of the people in the Shura team could not stand it anymore.

Many people collapsed directly on the ground.

Faced with the sound wave attacks that are pervasive and directly attacking the internal organs, they knew that it was useless to just cover their ears.

"I didn't expect the power of sound waves to be so terrible!" Zhang Yang carried Chen Lang on his back. At this time, Chen Lang had already fainted, and Zhang Yang himself couldn't stand it anymore, and blood gradually flowed out of the corners of his mouth.

Cao Nian's situation is not much different from Zhang Yang, and he is also very embarrassed.

In medicine, ultrasound can be used to break stones in the human body, which also illustrates the terrible power of sound waves.

If this kind of power is used to create a destructive weapon, it is not difficult to imagine how terrible it would be.

"Is there no way to resist sound waves?" Zhang Yang asked, "Can't the vacuum environment stop the spread of sound? Brother Cao, do you have a way to create a vacuum environment?"

Vacuum sound insulation is the basic physics knowledge.

"Create a vacuum environment - this is not something that can be done casually, so who do you think I am?!" Cao Nian wiped the blood from the corner of his mouth.

He looked at Chen Ming.

If anyone can do what Zhang Yang said, then it must be Chen Ming.

His frost field can even freeze matter from the particle level. To create a vacuum environment, it should not be a problem for him, right?

Cao Nian told Chen Ming about Zhang Yang's idea. After hearing this, the latter shook his head and said, "You may have misunderstood my ability. I can make the motion state of particles stationary, but I cannot discharge particles in a space. My ability can only weaken the effect of sound waves for the time being and cannot completely offset the sound wave attack."

"But even a little bit of mitigating the sound wave attack is not very important to us?" Cao Nian said.

"Okay!" Chen Ming nodded, "Everyone is moving closer to me!"

The frost realm has expanded.

A five-meter-wide circular space surrounded everyone.

Suddenly.

The sound coming from around was much smaller, and everyone felt relieved at the same time. This feeling was like being pulled from the darkness and suppressed darkness to a sunny place, and their breathing became much more relaxed.

"But - it's still someone's physical condition is getting worse!" Sakura wiped the blood on her mouth, not wanting to show her weak side in front of everyone.

"Someone must get the device that emits sound waves." Chen Qi said, "otherwise the sound will continue."

Because Shara's clone was condensed by chakra and did not have a true "body", it was less affected by sound waves, far less severe than everyone else. So Shara himself did not expect that the situation would become so serious.

Of course, they can attack with sound waves and forcefully break through to the next level.

But these sound wave attacks will not disappear because of this. As Chen Qi said, they must have someone to solve these devices that emit sound waves.

only--

Who can do it?

At this extremely urgent moment.

Liu Yan stood up as if nothing had happened. With his ability to fruit, his body structure was very different from that of humans, so the sound wave attack only made him feel a little uncomfortable and did not experience serious internal bleeding.

"Captain!" Guo Tianhe suddenly became nervous when he saw Liu Yan's actions, "What are you going to do?"
