Institute of Gene Production, Gene Modulation Laboratory

"Gurgling ......"

Shadow Four sleeps in the gene modulation cabin, and due to the rapid genetic changes and metabolism, the body releases a large amount of heat and boils the energy liquid.

In contrast, Shadow Four's breathing, heartbeat, pulse, and blood flow have completely stopped, and the brain waves are almost silent.

"Puff"

At this moment, Shadow Four's heart beat violently.

As Shadow Four's heart beats, infrasonic waves that are indistinguishable from the human ear diffuse, and the energy liquid in the gene modulation chamber ripples.

"Puff"

The energy liquid fluctuated violently, and the infrasonic waves were like ripples in water, penetrating the modulation chamber composed of high-strength glass and diffusing into the air.

At the city wall of Qingyun Base, the war has reached a fever pitch, and the land outside the city has been turned into a mud of flesh and blood.

The Heavenly Eyes Phantom above Xing Gui's head, his pupils radiated pure golden divine light, shattering those mutated birds that were about to break through the sky defense line.

Chen Huiyu kept bending his bow and shooting arrows, sending out energy arrows one after another, plowing the blood ** gully in the beast tide, and then being filled up in an instant.

"Boom ......"

From time to time, there is magma rising into the sky in the flesh and mud, not only killing the zombies and mutant beasts hidden in the land, but also causing a small sea of fire on the ground.

It's just that at this time, Xing Gui, Chen Huiyu, and Qin Yu all had exhaustion on their faces that couldn't be concealed, and there were a bunch of empty bottles of potions under their feet.

"Puff"

An invisible heartbeat sound spread throughout the entire Qingyun base, and even spread beyond the Qingyun base, making the movements of all living beings in the range uncontrollable.

"Puff puff ......"

The heartbeat gradually accelerated, so that the heartbeat of all living beings in the range instantly maintained the exact same frequency as this heartbeat.

"Puff"

When the heartbeat sounded for the last time, the heartbeats of all living beings stopped for two seconds before they resumed their normal beating.

"Whew...... Whew......"

"Hetz...... Hertz ......"

The battle stopped, and all humans and mutants gasped. Even zombies that didn't need to breathe and didn't have a heartbeat fell to the ground in large swaths.

"Smack...... Syllable...... Smack......"

At the entrance and exit of the Qingyun Base Gene Production Research Institute, there were bursts of crisp footsteps, which aroused the vigilance of the surrounding base guards.

"Click......"

With the sound of guns being loaded, all base guards pointed their guns at the inside of the institute.

"Smack...... Smack......"

The door of the research institute slowly opened, and in the shadows, Ying Si, who had a cold expression, walked out, showed a certificate, and said, "Return to normal vigilance!"

"Yes!"

Shadow Four didn't look at the base guards who put away their guns, and there was a unique perspective in his eyes in addition to the normal perspective.

In that perspective, there are countless transparent ripples that diffuse, reflect, refract, and penetrate in an arc, and the ripples in the space change to clearly outline everything around them.

"Huh!"

A sneer hung on the corner of Shadow Four's mouth, and with one step, the air in the void instantly turned into a transparent platform that distorted the light in the extremely condensed sound waves.

The platform gradually ascended, carrying the shadow four, towards the high altitude in the center of the base.

……

In a bedroom with a closed door, Lin Xi's hair was messy like weeds, his eyes were stained with dark circles, his eyes were not bright, his lips were chapped, and he sat quietly in front of the windowsill.

Ever since he came to the Qingyun base, Lin Xi had been locking himself in his bedroom, not seeing anyone, not knowing what he was thinking.

With the information access channel almost completely closed, Lin Xi obviously knew almost nothing about what was happening in the Qingyun base.

"That's? That's Shadow Four! ”

Lin Xi looked out the window in surprise, and his eyes reappeared.

"Isn't Shadow Four's ability ineffective, what's going on now, I seem to have missed something!"

"I still remember, I want to join Duan Yang's team, in addition to spying on the secrets here, it seems that I want to become a real powerhouse!"

"This world is originally the law of the jungle, if it weren't for Dad's protection, where would I have the opportunity to keep my naïve thoughts now!"

"Duan Yang, thank you very much, break my innocence with your own hands, and face the true side of this world!"

"I, Lin Xi, must work hard and strive to become a real powerhouse, not a flower in a greenhouse!"

In Lin Xi's eyes, a raging flame appeared.

With the help of Duan Yang, Lin Xi finally reshaped his three views and walked towards a path full of unknowns.

……

Shadow Four flew high in the air in the center of the base, and the countless sound waves around him were surging within a radius of ten meters, and the audible sound waves, inaudible infrasound waves, and ultrasonic waves converged.

The air was chaotic, distorted, bursting, and flowing in those churning sound waves, and the light was uncertain, making those who saw it feel sickened and dizzy.

"Humph!"

Shadow Si snorted coldly, and in the energy accumulated around him, an invisible energy was suddenly stimulated, spreading in all directions in a spherical shape.

"Plop...... Plop ......"

In the Qingyun base, all the soldiers only felt a depression in their hearts, and there was an extra lead sinker in their hearts, their qi and blood surged, and their faces flushed.

As for the zombies and mutant beasts outside the Qingyun base, they quickly fell to the ground like cutting wheat, and even foamed at the mouth.

"The ability I just got, I'm really still a little unaccustomed!"

Kagei sighed as he noticed the warriors who had been affected by his own attack.

"But ......"

Shadow Four closes his eyes, and the sonic attack he sent out before is reflected by the object, and is once again picked up by Shadow Four's ability.

In addition, after these sound waves are received, the psychic auxiliary brain quickly analyzes them, and obtains information about all the surrounding materials and creatures.

Resonance frequency, material density, physical structure, physiological structure, etc., and even the vulnerability points of countless substances and organisms.

"Now, it's much easier to clean up these slags!"

"Boom"

Around the shadow, as the ability was activated, countless sound waves in the form of blades erupted, like a sonic tsunami raging.

The sonic blades passed through countless buildings, and even through a large number of Ability Warriors, but the Ability Warriors were unscathed, as if those sound blades were phantoms.

However, when those sonic blades touched the screen of those mutant beasts and zombies, they resonated with their specific frequencies, and instantly exploded with terrifying power.

"Poof......

In a series of blood sprays, countless mutant beasts and zombies, under those sound blades, disemboweled, and shattered.

The sturdy scales, the tough cuticles, the thick layers of fat, under those sound blades, lost their proper defense.

Only those zombies and mutant beasts that can manipulate energy can forcibly weaken and neutralize these sound blades through energy.

At this moment, Shadow Four seemed to have become a god high above, and with a wave of his hand, thousands of living beings flowed into a river of blood.

"Humph!"

Shadow Four snorted coldly, but he also knew that the reason why his sound blade was able to treat those defenses as nothing was because of the resonance of a specific frequency, and the attack on vulnerable points.

In fact, the energy of those sonic blades is not very large, and even a fragile blade of grass is difficult to tear.

When sonic blades encounter energy defenses, these sonic blades can be easily neutralized by energy.

"In that case......

"......"

With a wave of his hand, the sound waves around his body condensed, turning into dozens of silver-white string moon-shaped blades that were like substances. The blade rotates continuously, rippling in the air.

"Go!"

The one-meter-long String Moon blade spun at an extremely fast speed and disappeared in an instant, and the remaining mutant beasts and zombies separated before they could react.

After Shadow Four attacked, he ignored the fate of those mutant beasts and zombies, and instead stared sharply at a small hill in the distance.

"Oh no, it's been discovered!"

The blood fox looked frightened, he didn't expect that the leader of the Qingyun base, after taking the main force of the base away, actually hid such a powerful character.

"Bloody escape!"

The blood mist around the blood fox rolled, turning into a blood light and flying away into the distance.

"Want to run?"

Ying Si's palm turned over, the palm was upward, and a silver-white sphere the size of a ping-pong ball was condensed in the palm, and the sound waves inside were like substance.

"Stay for me!"

The silver-white sphere in the palm of Shadow Four disappeared instantly.

How fast is the speed of sound? At about 340 meters per second, it is an unattainable speed for many people, even the Adepts.

However, when the distance between Shadow Four and the Blood Fox is too far, even if Shadow Four's sonic attack is a sonic attack, it will be difficult to hit the Blood Fox.

This thought flashed through the blood fox's heart, and next, an extremely chaotic attack directly hit the blood fox's body.

At the last moment when the blood fox lost consciousness, doubts flashed in his heart, "Sonic attack, can actually reach supersonic speed?" ”
