I can go back to the mysterious age

At the same time, in the gray manor.

The three commanders and many doctors from the treatment center had just recovered from the loud explosion. Some of them were stationed in the other half of the manor, so they just rushed out of the building with confused expressions on their faces. Others crawled out from the cracks in the masonry with blood on their faces among the ruins of collapsed buildings, with totems flashing on their bodies.

No one died in the steam explosion just now. At most, they only suffered some injuries. Because the scuffle between Anthony and the blonde girl took place at an artificial lake, and Cassius was meditating there, so naturally no one dared to approach and disturb them. Therefore, the core and most powerful location of the steam explosion is not inhabited by people from the treatment center. At best, they were affected remotely.

At this moment, everyone rushed out of the building, thinking that an earthquake or enemy attack had occurred. However, a very conspicuous flash of fire in the sky attracted everyone's attention. The pillar of fire split the blue sky into two and defeated the thick clouds, like a sword of fire falling from the sky. The increasingly bright tip exudes terrifying heat and brightness. At first glance, it looks like there are two suns in the sky, one big and one small. Looking up, I immediately felt a sense of insignificance that a natural disaster was coming and a catastrophe was imminent! It made all the hairs on the body stand up.

"Meteorite!"

The fog man wearing a black cloak looked up to the sky with an unusually solemn gaze: "Looking in this direction, it seems like it is going to fall near the manor?!"

"Damn it, why did you come to us?"

The venomous snake formed by the condensed hair on the head of Nine Snakes is shaking uneasily at the moment, obviously aware of the oppressive danger in the sky.

Whoosh!

A dream-like high-speed afterimage flashed across the manor.

Otto smashed the wall all the way and arrived in the courtyard where the artificial lake was located. At a glance, he saw Ka Xiu standing quietly at the center of the explosion.

The windbreaker rustled and swayed like dark clouds in the strong wind.

"Sir, Yun..."

Before Shi Zi could speak, he was interrupted by what Ka Xiu said.

"Odo, take everyone in the treatment center out of the manor as quickly as possible. The further away, the better. Run as far as you can..."

"What about you?"

"This meteorite is coming for me." Ka Xiu turned around and said calmly.

After he said this, he glanced at the Devil's Book in his hand.

Interestingly, the last time the Curse of Doom summoned an out-of-control fighter jet that fell from the sky and exploded, this time it was discontinued and a meteorite was brought over. Card Xiu originally thought that after he became an extreme fighter, the upper limit of the curse of the Book of Devil would be the same. But he didn't expect that Anthony and the blond girl were just appetizers before the main meal.

And the main dish was this meteorite that was heading towards him.

Even the trace of this meteorite appeared far away. Maybe give yourself some reaction time? In other words, this meteorite is unavoidable and will definitely hit the target across a long distance!

"Interesting, very interesting, very interesting!"

A smile suddenly appeared on Ka Xiu's cold face, with a trace of rare excitement. It felt like everything was under his domineering control. And suddenly, something unexpected happened in a certain link, and something got out of control. That sense of being on the verge of losing control made Ka Xiu faintly intoxicated and even enjoyed it.

There is part of his bad taste in this, but more of it comes from the practice and interpretation of the way of boxing. If nothing is out of control and goes against his own ideas, how can Ka Xiu implement the absolute will in his heart?

The Devil's Book attempts to use a meteorite from the sky as a hindrance, that's just right! He used these fists to completely smash and destroy it!

"Hiss..."

Kaxiu stood quietly on the only flat piece of green land. From him came the sound of violent inhalation like an elephant's neighing, sounding in the air. At both ends of the nose, wisps of vortex airflow visible to the naked eye were drawn into it. Ka Xiu's chest suddenly expanded, and his thick ribs seemed to be holding up umbrellas!

Wisps of extremely dangerous aura gradually spread into the air.

Next to him, Odo disappeared in an instant after receiving Card Xiu's reply command. We are now organizing a rapid evacuation of the treatment center's personnel.

At the same time, there was a collapsed wall area at the edge of the courtyard.

Anthony and the blonde girl couldn't care less about their shock at this moment.

They also felt that the meteorite seemed to be falling on the manor head-on.

So I wanted to get away from this area quickly.

However, the two of them had been fighting for so long. They had gone all out and their strength was extremely exhausted. Not to mention the final duel of boxing moves, which even resonated and fused, increasing the power tenfold.

That move of Steam Skeleton was indeed powerful, but it also drained all the power from the two people's bodies, including their physical strength. Later, Anthony and the blond girl suffered serious internal injuries in the aftermath of the explosion. At this moment, they were worse than normal people and could only stagger around like cripples.

The hair on the whole body stood up in warning of danger due to the terrible threat that was about to come overhead. At this moment, the two people actually helped each other regardless of their previous grudges. Limping and stumbling towards the outside.

But obviously, they were too late.

After walking a short distance, both Anthony and the blonde girl gave up.

They all sat down on the ground, gasping loudly as if they were exhausted. Sometimes they looked up at the meteorite in the sky, and sometimes they looked at the black-clothed figure in the courtyard not far away, whose aura was becoming more and more powerful and domineering. While praying that the meteorite would not fall here, I was wondering what Card Xiu was going to do?

call out! ! !

The meteorite emitting blazing fire fell from the sky.

"It's over..."

"Dead!"

Looking at the meteorite where the crash site became more and more obvious, Anthony and the blonde girl were in despair. It really means being impartial and pointing straight to the villa!

In the courtyard, a figure slowly grew taller, and its clothes were torn. The purple apertures on the surface of the armor-like tough skin were exposed, with a magnificent color like diamonds.

In the acupoint, there seemed to be purple mist slowly spurting out, gradually covering the surface of the statue-like body. Ka Xiu slowly spread his hands and fixed them in the starting position of Nan Dou Yin Snake Fist, with his five fingers opening and closing like the fangs of a python.

Over the past few days, he has been challenging fighters in the Howling Canyon of the disaster world, and feels that his secret martial arts skills are getting stronger and stronger with each battle. Ka Xiu has even been able to use secret weapons such as the Black Moon Pupil King Kung Fu Huan Yin Fist to create a Huan Yue Fist for Odo to experiment with. As for his own boxing skills, he has naturally been honing and improving. The most important one is of course Nan Dou Yin Snake Fist.

The South Dou Sound Snake Fist originally only had one move, the Roaring Sound Gun, that could be used.

However, through Ka Xiu's accumulation of creation and combat practice, the other two ultimate moves have gradually been completed. One is called Star Python Strangulation, which is a close-range double-arm strangulation technique that carries terrifying explosive and tearing power. The other one is called Cross Sound Howl, with both arms crossed and slashing, releasing concussive fluctuations wantonly. Its origin is the dual sword technique from an unknown undead.

Therefore, Nandou Yin Snake Fist is already the same as Nandou Red Eagle Fist. It completes the three ultimate moves and forms a self-contained combat framework.

Of course, the pinnacle of this framework is naturally the ultimate secret of a boxing technique. The ultimate secret of Nandou Red Eagle Fist, the Blood Eagle Mouth, is like this. It has extremely terrifying single-target damage, penetrating damage, and decomposition damage.

Blood Fist was created by Feng Liusi and is the culmination of decades of boxing skills.

There is no doubt that the blood eagle mouth is a perfect fit for the ultimate secret of Nandou Red Eagle Fist. Even if Ka Xiu creates another move, he probably won't be able to surpass it.

So, he put all his energy on Nan Dou Yin Snake Fist.

When fighting in the Howling Canyon, most of them used Nan Dou Yin Snake Fist to fight against numerous undead souls, and they encountered no less than a hundred battles. Finally, after an exhausting fight, everything returned to calm, and Ka Xiu felt infinitely lonely. At this moment, he heard the cry of the canyon.

It was a kind of howling, but it was actually the sound caused by the constant collision and friction of strong winds blowing through the interior of the canyon. All the time, it bounces back and forth.

The wind is like this. Can the sound, force, and explosive impact also be like this? ! If all constraints are compressed in a closed space, sound will continue to bounce around and form echoes. The shock wave will circulate back and forth, overlapping again and again. Although it will fade, the utilization efficiency will be ten times or even dozens of times higher than before! Echo Force can create a blasting shock effect like an explosion. If this effect can be continuously superimposed...

One level of blasting, two levels of blasting, one hundred levels of blasting, one thousand levels of blasting!

There are also shock waves caused by explosions, hundreds of times superimposed together. Trapped in an environment, constantly destroying and impacting all matter.

Who can bear it? !

It's like a room that can echo continuously, let's call it a sound nest. In this sound nest, sounds are convection and colliding wildly, which will definitely bring about terrifying howls! Replacing sound with force is the same.

Therefore, under the special environment of the Howling Canyon, Kaxiu continued to experiment with the effect of Echo Force again and again, and constantly adjusted his power. Finally, not long ago, he created his own prototype of the ultimate secret of Nan Dou Yin Snake Fist. Although it is a prototype, it already has at least 80% of the charm of the ideal perfect state, and the same is true in terms of power.

Ka Xiu directly called this move: Sound Nest Convection!

Since it was still in the experimental stage, he had never used this technique against any object that threatened him. And isn’t the current situation just right? A terrifying meteor falling from the sky!

Use sound nest convection to completely destroy this great natural force!

How exciting and satisfying would that be?

At least, Ka Xiu's whole body was trembling now, and his eyes had completely turned into a pure deep purple, exuding a cold and sacred feeling that was ruthless.

On the ground, he opened his hands toward the sky, and his grasping fingers were clustered together, like the jagged fangs of an ancient monster.

"Anyone who blocks my will will be howled to pieces!"

Starting from the roaring first word, Kaxiu's voice rose rapidly, as if a tangible sound wave flowed into the sound nest and began to vibrate and convection wildly. Immediately after the second word, there was a majestic and powerful echo. The third word, the fourth word, and finally all the way to the end. Card Xiu's trembling sound was already overlapping with the horrifying sound of countless people shouting at the same time, like the roar of an evil spirit in the depths of hell.

Bang! Boom boom boom boom boom boom…

Groups of concussive shock waves that were almost visible to the naked eye were gathered together by an unknown force, stacking up and accumulating like waves. The air was brought out with light white lines visible to the naked eye. From a distance, it seemed like compact petals suspended in the air, withering and growing crazily.

The ground shook violently, and a deep pit the size of a house appeared in the courtyard. At the same time, a black figure rose into the sky.

He seemed to be stepping on a giant purple python. The hundreds of meters long scaly python leaped out from the ground like an evil dragon, constantly accelerating!

Several sonic booms were heard in the air, leaving a mushroom-shaped white mist.

At this moment, look from afar.

All that could be seen on the horizon was a blazing fire falling from the sky and a huge purple pillar rising from the ground, colliding violently in mid-air!

Buzz! Buzz buzz buzz buzz…

Everyone's ears seemed to be deafened, and scarlet blood slowly flowed from their facial features. The whole person showed an extremely uncomfortable expression of pain.

In mid-air, the core position of the collision.

"Voice Nest Convection!!!"

Card Xiu's figure suspended in mid-air disappeared instantly, replaced by terrifying fluctuations that spread crazily from that point as the core. That's the wave, that's the sound wave, that's the air pattern, that's the echo power visible to the naked eye! In an instant, all the echo energy was released from the body.

A torrent of power spread crazily in the space, crowding out everything.

It seems to have no rules, but there is a combination running secretly. If you look down from the sky, you will find that these ripple-like whistling and echoing sounds are like python scales, spontaneously forming a huge sound snake. The sound snake swam in the rippled sea and reached the edge in an instant. The snake's body rotated rapidly, restraining the entire Ripple Sea. And this is the echo nest that breeds convection!

In less than a blink of an eye, the sound snake had already settled on the edge of the sound nest, and opened its mouth to spit out the echo power inside. The echo force shot out, quickly reached the surface of the snake body at the other end, and was bounced back by the scales. This back and forth cycle forms an extremely high-speed frequency. It caused the surrounding air to escape rapidly.

Boom!

The meteorite carrying the terrifying power of falling was wrapped in a sound nest.

Suddenly, an unimaginable collision and bombing occurred inside.

Layers upon layers of densely packed ripples hit the surface of the meteorite, producing explosive shock effects again and again. Crazy accumulation, crazy gyrations.

Bang bang bang bang bang bang... click!

Finally, a strange sound appeared among the repeated blows. A long and narrow mark suddenly cracked open on the surface of the huge, integrated meteorite. Moreover, this trace quickly spread to every corner of the meteorite. Like a spider web, it wraps around the entire boulder.

call out! A black figure leaped over at great speed on a giant python.

This last punch was thrown!

Bang!
