Chapter 443 Breaking Three Limits, Challenging the Sound Barrier! (Happy National Day)
Around 4 a.m., a light drizzle began to fall.

The world seemed to have been painted with a layer of ink.

The distant mountains slept in the dark hue, their outlines blurred and indistinct.

A light mist drifted across the surface of Yulong Lake, resembling a giant piece of black jade being moistened by rain.

In the stillness of the night, where the sound of raindrops pattering could be heard, a figure was running along the lakeside road.

He was completely naked except for a pair of bright red athletic underwear, his bronze skin gleaming faintly under the sparse streetlights.

Rainwater slid down his resolute face, soaking into his neck and mingling with the steam rising from his chest.

The running speed doesn't seem very fast; it's about the same as the normal speed of an electric scooter traveling in the city.

But his figure appeared extremely graceful, with his long legs striding out with even amplitude and his steps as light as if he were stepping to a silent rhythm.

Even every swing of the arm, every breath, was full of rhythm, quietly blending into the quiet rainy night.

He wasn't simply running; it was more like he was using his body to experience his surroundings.

Skin detects the density of raindrops, ears discern the direction of the wind, and eyes analyze changes in wind resistance.

The bare soles simultaneously sense the subtle undulations of the road surface, coordinating every movement of muscles and bones to ensure sufficient cushioning through gentle flexion.

"Uu——"

Fang Cheng let out a soft breath, his breathing deep and long.

He had been running around Yulong Lake at this speed for almost ten minutes.

For ordinary athletes, even just two or three minutes of "jogging" is enough to make them breathless, sweaty, and their calf muscles start to ache.

But for Fang Cheng, this amount of exercise was just the beginning of his morning workout, serving only as a warm-up.

At this moment, the subtle "clicking" sound of joints and muscles loosening up had long been lost in the sound of rain.

With each step, I could clearly feel the elasticity of my calf muscles and Achilles tendon.

Like a tightly wound spring storing energy, the force is transmitted from the arch of the foot to the thigh, and then steadily supported by the core muscles.

The entire body is like a precisely lubricated machine, with every gear fitting perfectly.

It has already reached its peak condition and is just waiting for a signal to unleash its amazing power.

A sharp light flashed in Fang Cheng's eyes as he looked at the road stretching straight ahead into the darkness.

"This is the time."

He let out a low shout, leaned his body slightly forward, and as his feet landed, the way he exerted force suddenly changed.

The next second, he unleashed his full power, and his entire body's muscle fibers seemed to ignite instantly.

Bang!
A dull thud exploded in the rainy night.

The damp asphalt road underfoot suddenly sank into a shallow pit, and mud, water and gravel splashed in all directions.

That was the damage caused by Fang Cheng's powerful push off the ground with his feet. The powerful propulsion made him shoot forward like a cannonball.

His 65 points of strength attribute were on full display at this moment.

With each push-off, the triceps surgica of the calf muscles bulge suddenly, taut like a hardened block of iron.

The quadriceps, hamstrings, and gluteus maximus contract and extend with exaggerated amplitude.

Then, like a bowstring stretched to its limit, it propelled its body forward with a sudden burst of energy.

Even the arm-swinging motion becomes part of the power output.

The deltoid, pectoralis major, and latissimus dorsi muscles work together to provide a powerful and stable reaction force, which, combined with the twisting of the core muscles of the waist and abdomen, maximizes the efficiency of the body's kinetic energy.

All the muscle groups involved in running are contracting and relaxing at a frequency that exceeds the limits of ordinary people.

Accompanied by the crackling sounds of muscle fibers working at high speed, it's as if countless tiny spark plugs are igniting simultaneously inside the body, unleashing an astonishing thrust.

His 64 points of agility became a "stabilizer" during his high-speed movements, allowing him to maintain incredible balance and coordination even at such terrifying speeds.

Even if the road surface is uneven, occasionally stepping on puddles or pebbles can cause lateral deviation.

He can also quickly correct his posture in the nick of time by making subtle adjustments to his ankles, knees and hips, and by engaging his core muscles in time. The process is so smooth that there are no deviations at all.

In this way, Fang Cheng almost completely deviated from the category of "running" and became more like an object flying close to the ground.

Using the instantaneous propulsion from pushing off the ground with both feet, it continues to speed forward at high speed in a manner that defies the laws of physics.

………………

100 m/s!
150 meters per second!
200 m/s!
230 m/s!
The numbers on the sports watch screen were jumping wildly like a runaway dashboard, clearly exceeding previous peak values.

The speed instantly reached its limit, and the sound of the wind in my ears quickly changed from a low whistle to a sharp screech.

The fine rain, which was originally fine, now felt like countless tiny needles, densely and fiercely pricking the skin, bringing waves of stinging pain.

But the pain did not frighten him; instead, it acted like a stimulant, making his fighting spirit boil even more.

"not enough!"

A burning light flashed in Fang Cheng's eyes.

After absorbing the flesh and blood of the Crimson Eye, his strength, agility, and constitution all broke through the 60-point mark, reaching a level he had never reached before.

This early morning run in the rain was intended to test the potential of this new body and push the boundaries of human physiology.

How can we stop at such a small point?

As the thought crossed his mind, his heart, like an engine, suddenly began to beat faster.

The deep, rhythmic thumping of the heart pumped powerful blood and energy throughout the body.

The already rapidly functioning muscle fibers then contract and relax at an even more astonishing frequency.

Then it unleashed an even stronger thrust, propelling its body forward.

The asphalt road beneath my feet quickly transformed into a flowing black ribbon of light in my field of vision.

The trees, railings, and sparse streetlights on both sides all became blurry shadows.

Fang Cheng felt as if he had stumbled into some kind of ultra-high-speed channel.

Everything in the world was instantly stretched into a series of continuous straight lines, weaving a strange web of light in the darkness.

250 m/s!
270 m/s!
290 m/s!
………………

The numbers on the sports watch screen were like runaway horses.

The displayed speed has reached a level that is unimaginable to ordinary people, surpassing the levels of real high-speed rail and civil aviation aircraft.

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

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

Each time you lift your leg and exert force, it consumes many times more energy than before.

Inside the chest cavity, the breathing technique had already reached its maximum.

Each deep breath felt like forcibly filling my lungs with cold air and rainwater, bringing waves of burning pain.

Fang Cheng remained calm, and his breathing did not become disordered as a result.

Although his speed at this moment far exceeds the limits of ordinary people, this is not the end.

His goal was never to "surpass ordinary people," but rather to reach that threshold he had long coveted, a threshold that could rewrite human cognition.

Sound Barrier!

However, to break the sound barrier, one must confront the fundamental issues stemming from the human body's physiological structure.

It's not just about overcoming the increased air resistance; more importantly, it's about whether the body can withstand the enormous strain brought about by such terrifying speed.

300 m/s!
310 m/s!
320 m/s!
When the peak running speed finally exceeds 300 meters per second and is about to approach the speed of sound.

Fang Cheng began to feel the truly terrifying challenge facing his physical body. The wind howled in his ears; it was no longer the wind, but a whistling blade cutting through every inch of his exposed skin.

With each step he took, the oncoming air currents transformed into countless hands, gripping him tightly as if to tear him apart.

He could feel the air in front of him being violently compressed, forming invisible giant waves that kept pounding against his chest.

With each breath, the lungs endure a tremendous pressure difference, as if being violently squeezed by an invisible hand, threatening to burst at any moment.

Even more terrifying is that the high-speed compressed air creates a frictional effect that is almost tangible.

The drizzle continued to fall gently from the night sky.

But as soon as the raindrops touched Fang Cheng's body, they were instantly vaporized by the terrifyingly high temperature on his body surface, rising up wisps of white mist that could be seen with the naked eye.

Fang Cheng's skin began to turn bright red, like a branding iron, and fine beads of blood even appeared in his pores.

It was as if the capillaries ruptured instantly under high pressure and high temperature, like countless tiny sparks crackling on his bronze muscles, bringing unbearable burning pain.

In addition, Fang Cheng felt a violent tremor that went deep into his bones.

This is not fatigue, but rather the resonance between the entire skeleton and muscles and the surrounding air as they are enveloped by high-speed airflow.

The spine, joints, and even internal organs were trembling slightly, as if they could be torn apart by this resonant force at any moment, causing the entire body to fall apart completely.

This is no longer a simple speed race, but a severe test of the essence of life, a head-on battle against the physical laws of nature.

"Roar!"

Fang Cheng roared inwardly.

The sound existed only in the depths of his soul, yet it seemed to resonate throughout the entire world.

His eyes were wide open, reflecting a blurry and distorted world in his pupils.

And then there were the raindrops, dancing wildly in the wind, piercing the sky like steel needles.

Is it painful? Of course it's painful!

The tearing of muscles, the trembling of bones, and the pressure on his internal organs all reminded him that his body had reached its limit.

But above this pain is an unprecedented wildness and pleasure!

Fang Cheng felt the explosive power of every muscle and the boiling of his blood in his veins.

Even feeling the freedom of breaking free from constraints and transcending all things after life force has been squeezed to its limit.

He wasn't running; he was crashing, tearing through the air, launching a primal challenge against that invisible barrier.

Sweat, rain, and blood mingled together, blurring his vision but making his inner desires even clearer.

Faster! Even faster!
325 m/s!
330 m/s!
………………

The peak speed displayed on the sports watch screen is still slowly climbing.

However, the resistance for every few meters of ascent felt like climbing a mountain.

The air in front was compressed wildly, forming a dense barrier invisible to the naked eye.

Each impact sent his body trembling violently, as if he had crashed into a wall full of tension.

That is not simply wind resistance, but the most stringent "sound barrier" in physics, a terrifying realm that the human body has never ventured into.

Fang Cheng's body was already burning up to the extreme, and his skin even emitted a burnt smell, which could be faintly smelled in the rain.

The muscle contraction frequency has also reached its limit, and every fiber is trembling under excessive load.

They were convulsing and howling, as if they would be torn apart at any moment.

But thanks to Fang Cheng's iron will, he miraculously persevered.

335 m/s!
336 m/s!
………………

The fluorescent numbers on the watch screen were still flashing.

The peak running speed climbed upwards with a slight increase.

Fang Cheng, enveloped in thick smoke, flew past the lakeside road like a jet plane.

That's the phenomenon of rainwater and sweat evaporating instantly under the incredible heat on the body surface.

Fortunately, it was still early morning and there were no pedestrians on the road, so this strange phenomenon did not fall into the sight of others.

In addition to the high-temperature steam generated by friction, there was also an invisible airflow surrounding Fang Cheng's body.

This subtle and restrained airflow greatly counteracts the oncoming wind resistance and enhances balance and coordination.

The "Strong Wind" skill effect played a crucial role at this moment, allowing Fang Cheng to conserve more of his stamina.

Otherwise, under such extreme conditions, his bodily functions would have collapsed long ago.

However, this only mitigated the impact from the outside.

The resonance effect of the high-speed airflow on his internal organs, along with his near-self-destructive body temperature, continued to relentlessly attack his body.

Fang Cheng's eyes were bloodshot, and deep within his pupils burned two blazing flames.

In the boundless darkness, he vaguely glimpsed a door leading to an unknown world.

At this moment, time seemed to be infinitely stretched.

Fang Cheng had only one thought left in his mind.

Sprint!

Sprint forward a little more!
I'm going to break through that barrier!

I want to see with my own eyes just how far the human body can go!

"Ho-"

Fang Cheng exhaled and made a sound to enhance his strength.

The muscles in his legs suddenly exploded again, and all the power in his body was concentrated into a single point at that moment.

boom!
The asphalt road beneath our feet was dented and cracked with countless fine fissures, asphalt debris mixed with rainwater exploded in all directions.

Fang Cheng was like a red-hot divine weapon, slashing fiercely at the invisible barrier that was already faintly visible in front of him.

Boom——

A deafening roar erupted, like thunder breaking on the tranquil shores of Yulong Lake.

It wasn't Fang Cheng's roar, nor the sound of the road cracking beneath their feet.

That was the echo of air being torn apart, compressed violently, and then expanded violently.

That is the legendary "sonic boom"!
At the same time, Fang Cheng felt his body being violently propelled forward by an overwhelming force, and then violently pulled backward by an equally powerful reaction force.

It felt as if space itself was being squeezed and distorted around me.

A sharp, piercing pain immediately shot through my eardrum, as if a steel needle had been inserted.

In the dynamic field of vision, Fang Cheng even saw a semi-transparent shockwave spreading rapidly in all directions from itself as the center.

Where the shockwave passed, the fine rain was instantly dispersed, and a clearly visible ripple spread across the lake surface.

Even the branches and leaves of the trees on both sides trembled slightly.

It worked!
I actually broke the sound barrier with my own body!

In that instant, Fang Cheng felt an unprecedented sense of freedom and ease.

The invisible barrier that had been pressing down on him was finally trampled under his feet and torn to pieces.

My running speed reached a whole new peak, and the entire dark and damp world became bright in my eyes.

It seemed as if it had truly merged into the wind and become part of the light.
