Compared to the demon race, whose cultural heritage is quite shallow, humans have much more mature methods of controlling extraordinary powers. The Super Research Institute of the Dragon Country is an organization established to research the extraordinary.
Although Xiong Gun belongs to the demon race, the Super Research Institute has a considerable understanding of the evolutionary systems of demons, even surpassing that of the Demon Country in some aspects.
Furthermore, Xiong Gun's control over sonic abilities shares similarities with human sonic abilities. With the assistance of the Shenhua Bureau and the Super Research Institute, scientific theories were combined with extraordinary abilities, leading Xiong Gun's use of sonic powers to an extremely refined level.
Unlike the sea lion, which only knew how to roar mindlessly.
The terrifying sonic energy, driven by the demon core within Xiong Gun, began to probe the depths of the earth like radar. Soon, Xiong Gun had complete control over the sea lion's movements.
The next second, Xiong Gun closed his eyes, transforming himself into a infrasound source. His primal power, carrying the infrasound, washed over the sea lion moving underground.
Unlike ultrasound with its short wavelengths, infrasound typically has very long wavelengths. Some infrasound can even circle the Earth two to three times. When its frequency matches or is close to that of human organs, it can cause organ resonance, inflicting significant damage to the human body, and in dangerous cases, even leading to death.
Therefore, before the demise of many nations, infrasound was explicitly listed as a public nuisance by many countries, highlighting its danger.
And when infrasound was combined with Xiong Gun's primal power, the damage it caused undoubtedly became even more terrifying.
"Heart frequency 1.862Hz, brain frequency 2.64Hz, demon core frequency 1.0111Hz... Found your frequency!" Xiong Gun murmured, his dark eyes snapping open.
Then, his body began to tremble violently.
"How is this possible!" the sea lion, which had been swimming underground, cried out, clutching its heart.
The next second, its demon core began to vibrate intensely. Endless energy poured out uncontrollably, flowing to its limbs and extremities like a mountain flood. Simultaneously, its heart began to tremble in sync with the infrasound frequency emitted by Xiong Gun, and its brain was struck by a sharp pain.
The invisible sonic energy penetrated every inch of its flesh and blood. It charged out of the ground frantically, wanting to escape this hellish torment.
But it was too late.
*Puff!*
The moment it burst out of the ground, its massive body exploded into a cloud of blood mist in mid-air, like a balloon filled with red dust being punctured, thus perishing.
"Battle concluded, victor Dragon Country's Xiong Gun!" the referee from the Demon Country announced the result expressionlessly.
"This is what you call scientific extraordinary abilities!" Xiong Gun chuckled, enveloping the blood mist with spiritual energy and storing it in his personal spatial acupoints. This blood mist was precious; it could be used to make various extraordinary potions or to irrigate spiritual plants, fetching a good price for snacks.
"Gun Gun, you're amazing, I love you to death!" Xiong Gun's caretaker shouted excitedly, her face beaming with joy, as if she were the one who had won.
Xiong Gun transformed into human form, a gentle smile appearing in his eyes as he looked at the caretaker's sunglasses, and flew towards her.
"Weiwei, you have to give me an extra meal tonight!" Xiong Gun returned to the caretaker's side, his face displaying an innocent and honest smile, as he put his arm around the girl's shoulders.
"Okay, I'll make you braised wild ox bone with bamboo shoots tonight!" the girl giggled, playfully pinching Xiong Gun's waist.
The audience watching the live broadcast of the match also erupted in cheers after Xiong Gun's victory:
"Holy crap, who said national treasures only know how to act cute?! This kind of power could destroy a city, you keyboard warriors!"
"Gun Gun, Mommy loves you!"
"Gun Gun looks so cute in human form too, like a steamed bun with two black bean dots for eyes. My girlish heart..."
"Is this the horror of sonic extraordinary abilities? The Lighthouse Country inventor Tesla once said that with a resonator, he could split the Earth in half. Will Gun Gun reach that height in the future? With his ability to wield sound waves as his own, isn't he a terrifying resonator himself!"
"I've never felt sonic extraordinary abilities to be so powerful as I do at this moment."
"Holy crap, look at Ring 8, the octopus monster has appeared!"
"..."
On Ring 8, Kimimaro, transformed from Yu Zhibo's consciousness clone, had sharp bone spurs growing from various joints, resembling a humanoid hedgehog. He was battling an A-class, ninth-tier peak octopus demon, attracting the attention of many spectators.
The octopus demon had a full sixty-four tentacles, each over two hundred meters long and covered in terrifying suction cups. This was an octopus mutated by nuclear radiation, a new species that had evolved by combining radiation power with demon energy, making it more terrifying than conventional sea monsters.
It was precisely for this reason that it could represent the Demon Country's contestants in the arena battles.
At this moment, its sixty-four tentacles were constantly pounding the ground, turning everything around into ruins.
In comparison, Kimimaro, constantly shifting between the tentacle attacks, appeared like an ant. Each evasion was a narrow escape, making him seem to be in a precarious situation.
*Chii!*
Suddenly, a cold light flashed. A sharp bone blade severed the octopus's massive tentacle. The severed tentacle writhed on the ground after falling, and to everyone's astonishment, it grew new octopus heads and tentacles, eventually transforming into a small octopus dozens of meters tall. It let out a screech like fingernails on a chalkboard and swung its tentacles towards Kimimaro.
"Splitting and regeneration... what a disgusting ability!" Kimimaro frowned and leaped back, dodging a tentacle that slammed down from above. A scene from Naruto, where Sasuke fought Deidara, flashed through his mind.
He flicked his right hand, and the bone blade that grew from his palm detached and was discarded. Then, another two-meter-long bone blade grew. Unlike the one he discarded, this blade flowed with a faint light, as if made of white jade.
This light was the manifestation of Kimimaro's condensed primal power, allowing his attacks to transcend the realm of physical attacks.
The tentacle swung again. Kimimaro slashed with his blade, and the tentacle was severed once more. After writhing on the ground a few times, it did not transform into a small octopus.
"That's better, at least it's not that absurd!" Kimimaro's lips curved into a smile, but he was soon astonished to find that multicolored energy flowed from the severed tentacle, and new tentacles grew again.
"It can only prevent the tentacles from becoming new individuals, but it still can't stop their regeneration..." Kimimaro sighed inwardly as he watched another tentacle strike. "Fortunately, it's me they're facing. If it were any other regular ability user, they might have truly perished under the tentacles of this nuclear-polluted octopus."
"In that case, I'll have to use my ultimate move!"
Kimimaro lowered his eyelids, bringing his fingers together before his chest: "Earth Style: Earth Submergence!"
As the ninjutsu was unleashed, earth-attribute spiritual energy turned the ground beneath his feet into a swamp, and he began to sink rapidly into the ground.
Then, countless sharp bone spikes erupted from the ground.
"Shikotsumyaku: Sawarabi no Mai!"
