Just when Tugang was about to be completely killed by Oka with a sword.

In the room on the third floor of the shop not far away, the red-haired royal sister team that had been lurking for a long time had all five of them changed into special black combat uniforms and black combat helmets, and they were holding various weapons of different styles and full of science fiction in their hands.

On the floor behind the five people, a black device that looks like a miniature signal tower stands half a human, and the blue signal light on the top of the device flickers regularly, as if waiting for something.

The average person's mental state should be the most lax in three situations, the first is when he is sleeping, the second is when he is snapping, and the third is when he thinks he wants to do something, that is, before the often said success.

As a veteran adventurer who has experienced countless battles, the red-haired royal sister obviously understands this truth very well, so the moment Oka raised the long sword in her hand, the red-haired royal sister, who had been watching coldly, decisively gave the battle order.

"Turn on the infrasonic device! Kill mission targets! ”

"Yes!" ×4

At the same time, a look of excitement flashed on the face of the prosthetic-eyed young man hidden in the black combat helmet, and he pressed a red button similar to the detonator device that had been pinched in his hand.

In an instant, the blue signal light on the top of the mini signal tower device behind the five people turned red, and streams of extremely strong low-frequency sound waves that could not be captured by ordinary people's hearing surged out of the signal tower device and spread at the speed of sound!

At the same time, except for the young man with a prosthetic eye, the red-haired royal sister and the other three teammates directly smashed through the wooden wall that was not solid and jumped towards the street below, and the weapons in their hands began to flash with various lights that seemed to be charged.

The prosthetic-eyed young man took out a black sniper rifle nearly two meters long from his watch, aimed at Oka not far away in less than a second, and then pulled the trigger without hesitation!

……

Regarding Okka's attempt to snatch people's heads, the three of Yato just watched silently and did not stop it, because killing Tugang with his own hands would not bring them (her) any benefits.

Although the three of them admired Tu Gang's tenacious will, in the final analysis, Tu Gang was an enemy, and Oka couldn't find any reason to stop them if they wanted to kill Tu Gang completely.

The silver-white sword reflected a somewhat dazzling cold light in the sunlight, and fell towards a crumbling figure steel with a trajectory of death.

Time seemed to slow down in this moment.

Oka even had the happy smile of a thug in his hand.

In the next second, an invisible sound wave spread.

In an instant, Oka stiffened unnaturally whether it was the smile on his face, the arm wielding the sword, or even his entire body.

In the next 0.1 seconds, a ray of incandescent energy the thickness of the bowl pierced through the location of Okka's head!

The extreme heat carried by the energy ray instantly vaporized Oka's entire head into nothingness, and then grazed the right shoulder of Tu Gang, who was very close to Oka and shot into the ground, leaving a round hole with a red edge in the ground, and at the same time, it also burned the right half of Tu Gang's shoulder and part of the armor into flying ashes.

Tu Gang, who was also affected by the impact of invisible sound waves, his already dying body suffered such a serious injury again, even if his will was firm, he could not resist the successive calls of death, and the blood-red eyes symbolized the look of life had gradually dimmed, and his body slowly fell backwards as if he had completely lost his breath of life.

……

The so-called infrasonic wave refers to the sound wave with a frequency of less than 20HZ, in addition to having strong penetration, the biggest feature of infrasonic wave is that the frequency is similar to the natural frequency of human organs.

High-intensity infrasound waves can form a strong resonance effect with human body organs, tissues, etc., and then cause terrible damage.

The infrasonic device used by the red-haired royal sister and others is a weapon developed by the Metal Tide Guild specifically for humanoid organisms, which is not only extremely lethal to human races in a broad sense, but also has considerable effects on many humanoid races.

The intensity of the infrasound waves emitted, even at the minimum, can make ordinary people have muscle spasms in a very short time, brain nerves, and then complete incapacitation, coma or even shock.

The highest degree can instantly cause cell-level damage to the body of ordinary people, and then cause the structure of human cells and tissues to collapse, and turn into a pool of concentrated water in a very short time.

In short, it is an extremely terrifying weapon for ordinary humans, and it is also a great threat to many humans and humanoid adventurers who are not physically strong enough, and can form a powerful suppressive effect even if it cannot cause kills.

is something similar to a pseudo-special domain field.

The red-haired royal sister has to deal with the three of Oka and Yato, not to mention that the three of Yato are at least A-level or above adventurers, even if the relatively weak Oka is not comparable to ordinary people.

Therefore, this extremely precious infrasonic device was turned on seventy percent of its power.

No matter how high it is, even if the red-haired royal sister and the others wear special equipment with the corresponding shielding function, they will not be completely unaffected, and it will undoubtedly become a thousand self-damage to the enemy.

And even seventy percent of the power is already extremely terrifying.

Not to mention the crowd around them who were fleeing in panic, they suddenly began to fall down in pieces, their bodies convulsed, foaming at the mouth, and bleeding all over their bodies, even the A-level and above adventurers like the three of them were affected a lot.

At the edge of the big pit not far from Tugang, the three of Yato, who were also affected by the powerful infrasonic waves, instantly changed their faces.

The unnatural stiffness spread throughout his body, and the unusually blushing of the three Yato tried's exposed skin followed.

Before the three of them could regain control of their bodies from the sudden impact of the powerful infrasonic waves, the four red-haired royal sisters who rushed to the opposite side of the pit had already aimed the various technological weapons in their hands at the three of them.

In the hands of the red-haired royal sister, the tips of two pistols shaped like a crescent, the silvery-white light like moonlight almost overshadowed the bright sunlight - the first-generation Moonlight III. Light Energy Pistol, the high-energy laser rays emitted can easily penetrate all materials with a hardness of less than 50.

To the left of the red-haired royal sister, a strong man who is a head taller than the red-haired royal sister carries a giant cannon with the thickness of a basin more than one meter long and the internal electric light flashing - the first-generation Thunderbolt I plasma cannon, which fires high-energy plasma cannonballs that claim to be able to dissolve everything within ten meters of the target!

To the right of the red-haired royal sister, in the hands of a girl with eyes like eagle eyes, a lapis composite bow is regularly flashing with cyan light like wind whispering - the first generation of wind whisperer type I magic energy bow, made by mechanical energy technology combined with magic technology, has a strong destructive effect on energy barriers.

The last middle-aged man in his thirties half-squatted behind the red-haired royal sisters, in a posture of wanting to jump, carrying a dark metal greatsword like a door panel in his drooping hands, and invisible fluctuations were rapidly agitating in the big sword - the first-generation BFII.-type kinetic energy greatsword, which was claimed to be able to split a heavy tank with a single sword by accumulating powerful kinetic energy.

"The target of the mission has been killed by Xiao Ke! It's a rare opportunity! Kill these cubs now! ”

As the red-haired lady who was a little excited gave the order.

In an instant, four moonlit high-energy laser rays shot out from the tips of the crescent moon twin spears in the hands of the red-haired royal sister, and a plasma cannonball entwined with electric light blasted out from the barrel on the strong man's shoulder, followed closely behind, and two emerald green arrows entwined by the cyan wind whirlwind broke away from the eagle-eyed girl's hands, and the middle-aged man behind the three also jumped up with the help of the mechanical prosthetics on his legs, carrying a black metal sword.

The target is the three Yato, who are still trying to adapt their bodies to the effects of infrasound.

And on the way through which these attacks must pass, it is the figure of Tugang who slowly falls......

Time really slowed down at this moment, even standing still.

Because, a spiritual force that was so strong that everyone present could not understand it, carrying the great power of time, suddenly descended!

"I don't know what's going on, but you seem to be moving, so who is it! Courage for you! ”

The moment the calm words fell, the spiritual coercion like a heavenly collapse enveloped everyone present.

Everyone who had been frozen by the power of time suddenly had an almost identical thought in their minds - God, angry!
