Chapter 860: Chapter 860

This pre-dawn rain-soaked running session was meant to test the potential of this new physical form, challenging the boundaries of human physiological limits.

How can I stop when I’ve only reached this level?

As thoughts swirled, the heart within—like an engine—suddenly accelerated its pace, pumping immense blood flow throughout the body.

Muscle fibers alternately contracted and relaxed at an astonishing frequency, unleashing powerful thrusts that propelled his body forward.

The asphalt road beneath his feet swiftly transformed into a flowing black strip of light.

Trees, railings, sparse street lamps on both sides, all scenery blurred into indistinct shadowy figures.

Like entering some kind of ultra-high-speed tunnel, the world was stretched into endless straight lines, weaving a peculiar network of light in the darkness.

The numbers on the sports watch screen rampaged like an uncontrollable wild horse, reaching values unimaginable to ordinary people.

However, as the running speed further increased, the resistance Fang Cheng felt also rose exponentially.

It was an indescribable sensation of oppression, as if the surrounding air had turned into thick mud, clinging tightly to his body.

Every leg lift and exertion required multiple times the energy compared to before.

Within his chest, the Breathing Technique had already reached its peak.

Every deep breath felt like forcibly drawing cold air and rainwater into his lungs, causing fiery burning pain.

Fang Cheng’s expression remained stable, his breath showing no signs of disarray.

His current speed far exceeded the limits of ordinary people, but this was not the end. Latest content publıshed on noᴠelfire.net

He never aimed to merely "surpass ordinary people"; instead, he had long coveted that threshold capable of rewriting human cognition.

But for a body to achieve sonic speed, it faces fundamental obstacles from human physiological structure.

This is not merely about air resistance, but whether the body structure can withstand the immense load brought by such terrifying speed.

When the peak running speed finally surpassed 300 meters/second, nearing sonic speed.

Fang Cheng began to feel the true, terrifying challenges facing the physical body.

The wind shrieked by his ears; it was no longer merely wind but air blades whistling by, cutting into every inch of his exposed skin.

Every step forward faced a barrage of air currents like countless hands, gripping him tightly as if trying to crush him.

He could feel the air in front of his body being violently compressed, forming an invisible giant wave that continually pounded against his chest.

Every breath, his lungs bore a tremendous pressure differential, as if squeezed fiercely by invisible hands, ready to burst at any moment.

Even more terrifying was the palpable effect of friction brought by high-speed compressed air.

Though the light rain persisted, upon contact with Fang Cheng’s body, they instantly vaporized under the terrifying heat radiating from his skin, creating a visible white mist.

Fang Cheng’s skin began reddening like a heated iron, pores even exuded tiny Blood Beads.

This was the instantaneous rupture of micro blood vessels under high pressure and high temperature.

Like countless tiny sparks crackling on his bronze muscles, it brought unbearable burning pain.

He even felt a deep, bone-penetrating tremor.

This was not fatigue, but the resonance between his whole body’s bones and muscles with the surrounding air in the high-speed airflow.

His spine, joints, even internal organs were trembling slightly, seeming ready to be torn apart by this resonant force and completely falling apart.

This was no longer a simple race of speed, but a severe test of life itself, a direct confrontation with the physical laws of nature.

A roar erupted from within Fang Cheng’s heart.

That sound existed only at the depths of his soul, yet reverberated so much the entire world seemed to resonate.

His eyes opened wide, pupils reflected the fuzzy and distorted world, alongside rain threads dancing wildly in the wind.

They now truly felt like countless needles, fiercely piercing.

Yet this stabbing pain could not make him stop.

Pain? Certainly, pain!

The tearing sensation of muscles, tremor of bones, pressure within organs—all reminded him that his body had reached the limit.

But above this pain, there was an unprecedented wild pleasure!

Fang Cheng felt the explosive limit of every muscle, sensed the blood boiling in his veins.

Even felt the Life Force being extracted to the extreme, bringing a feeling of breaking free from constraints, elevating above all.

He wasn’t merely running; he was colliding, tearing through air, launching the most primal challenge against that invisible barrier.

Sweat, rainwater, blood mixed together, blurring his vision, yet making his inner desire clearer.

Faster! Just a bit faster!

The peak speed displayed on the sports watch screen continued to slowly and arduously climb.

However, every kilometer rise in resistance felt like overcoming a mountain peak.

The air in front of him compressed madly, forming a dense barrier invisible to the naked eye.

Each collision caused his body to reverberate intensely, as if crashing into a stretched wall full of tension.

This was not simple wind resistance but the most severe "sound barrier" physics poses—a terrifying Domain never ventured by human flesh.

And Fang Cheng’s body had already heated to the extreme, skin even emitting a charred smell faintly detectable amid rain and air.
