337: Chapter 337 Upgraded Lightness Skill, the Possibility of Becoming Spider-Man

Looking at the description of the "Absolute Control" special effect displayed on the panel, a flash of understanding crossed Fang Cheng's eyes.

From the perspective of sports biomechanics, the Pull-up exercise is fundamentally one of the most extreme ways to hone grip strength.

It requires the trainer to firmly hook their fingers onto a support, relying on the concentric and eccentric contraction forces of the forearm muscle groups to counteract their own gravity.

This process deeply stimulates the core hand muscle groups, such as the flexor digitorum, extensor digitorum, and even the palmaris longus in the forearm.

During the dynamic phase of practicing Pull-ups—when the body is pulling upward—the fingers and palms must actively tighten, generating explosive grip strength to fight gravity.

And in the static dead-hang phase, the hands need to continuously undergo isometric contraction to keep the body stable, which in turn trains the endurance of the grip.

Ordinary people can't do many Pull-ups. Aside from factors like weak back muscles, excessive body weight, and incorrect form, it is also directly related to the lack of endurance and explosive power in the forearm muscle groups.

Often, the hands lose strength first before the back muscles even reach their limit.

Therefore, many top rock climbers have fingers as tough as iron pincers.

They regard practicing Pull-ups and their various variations as the core method for honing grip strength, with its importance even exceeding that of back training.

After long-term training, it can significantly improve hand grip strength, reaching several times that of an ordinary person.

Now that he had grinded the "Pull-up" skill to the Grandmaster level, it was entirely reasonable that it could derive such a domineering special effect.

With his thoughts spinning like lightning, Fang Cheng could not wait to experience it for himself.

He quickly walked to the wall and picked up a brand new 20kg dumbbell in the corner.

His five fingers gripped and closed, slowly wrapping around the dumbbell's cold, knurled handle.

That rough metallic sensation was transmitted exceptionally clearly through the skin of his palm.

Fang Cheng did not exert force intentionally; he just stood naturally and gripped it naturally, just like picking up a heavy object normally.

In the next second, Fang Cheng's eyes focused, and his robust frame shook slightly.

Power instantly transmitted from his core along his spine to his shoulders and back, then pumped into his arms like a high-pressure pump.

Then, his forearm muscle groups suddenly bulged, the twisted muscle lines resembling intertwined steel cables.

All the power converged at the tips of his five fingers in a thousandth of an instant through the flexor and synergistic muscle groups!

"Creak—screeech—"

A teeth-gritting, chilling wail of twisting metal suddenly rang out in the quiet room.

It didn't feel like metal being squeezed; it felt more like a piece of wet wood being squeezed of its moisture by immense force.

Fang Cheng exhaled, slowly released his fingers, and looked closely.

On the hard cast-iron handle of the dumbbell, five pale white finger marks were faintly visible, as if branded onto it.

They gleamed with the unique pale luster of metal molecular structures being destroyed after suffering violent bending.

By visual estimation, the depth of this indentation was at least half a millimeter!

"Hiss... this is a bit ridiculous."

Fang Cheng muttered to himself.

Such solid cast iron in his hands actually seemed to have become a toy that could be kneaded at will.

To achieve fine motor control, the evolutionary direction of human fingers is far more focused on flexibility than pure strength.

The muscle groups involved in gripping and exerting force are already a relatively weak link among all the body's muscles.

Generally speaking, an adult's limit grip strength is only about one-fifth to one-tenth of the impact force generated by their full-force punch.

With Fang Cheng's current strength attribute close to 50 points, even without using the special effect boost of the "Qilin Arm", a simple straight punch could smash a clear fist print into an iron plate.

But that was the result of the whole body's strength transmitting through kinetic energy and concentrating at the fist.

To use five fingers, which have a relatively fragile structure and more isolated force-exerting muscle groups, to squeeze marks into cast iron of the same hardness, the difficulty increases geometrically.

Relying solely on his base strength attribute of nearly 50 points, wanting to achieve such an effect was nothing short of a pipe dream.

But now, the "Absolute Control" skill effect had brutally increased his instantly exploded grip strength by 1.5 times.

Only then did he barely touch the threshold of "fingertips radiating coldness, parting gold and breaking iron" described in Wuxia novels.

"It seems that with the steady increase of my strength attribute, purely snapping steel bars and iron rods with my five fingers is not out of reach either..."

Fang Cheng looked at the slightly deformed 20kg dumbbell in his hand, secretly glad.

Fortunately, the degree of deformation wasn't too exaggerated.

Otherwise, dealing with such a thing would really be a bit of a hassle.

After putting down the ravaged dumbbell, Fang Cheng lightly shook his hand, his gaze refocusing on the panel.

He looked at the description of the second special effect of "Absolute Control".

"Specialization of climbing ability, friction per unit area of fingertips increased by 1000%..."

Fang Cheng read aloud in a low voice, a hint of curiosity flashing in his eyes.

After thinking about it, he unbuckled the weighted barbell plates from his waist and dropped them onto the floor, making a clanging sound.

Then, stretching his muscles, he walked to the wall, reached out his fingers, and gently touched the wall painted with light blue latex paint.

"Zzzzz—"

The moment his fingertips contacted the wall, a wonderful sensation of adhesion was instantly transmitted from his nerve endings.

It felt as if billions of nanoscale bristles had grown on his fingertips, hooking into the microscopic pores of the wall that were invisible to the naked eye.

Through internal perception, Fang Cheng could clearly sense that at the moment his fingers contacted the wall, a powerful electrostatic adsorption force was generated at the microscopic level.

The latex-painted wall, originally as smooth as a mirror, actually felt as rough as 800-grit sandpaper under this touch.

"Is this trying to make me evolve into a gecko?"

Fang Cheng complained in his heart, then simply reached out both hands, spreading his five fingers like claws, and pressed them against the wall.

He attempted to cling to the wall directly with both hands and mimic a gecko, slowly climbing upward.

However, as soon as he exerted force, his body lifted slightly by less than a centimeter.

"Pfft!"

A slipping sensation of having nowhere to grip came from his fingertips.

"No..."

Fang Cheng shook his head.

The renovation master's work was simply too good.

So much so that the wall was too flat and smooth, without any visible protrusions at all.

Pure static friction was not enough to allow him to counteract his own gravity at a slow speed on an absolutely vertical plane.

However, being unable to climb slowly did not mean he couldn't conquer this wall.

Fang Cheng looked up at the wall, which was about three meters high, and the ceiling coated with putty powder at the top.

There, the I-beams reinforced for hanging sandbags and training equipment crisscrossed like an upside-down steel forest.

The "branches" within could indeed provide excellent handholds.

Fang Cheng's gaze narrowed slightly, and then he stood close to the wall again, bending his knees slightly.

Suddenly, taking a deep breath, he raised his right hand and grabbed the latex-painted wall with force.

At the same time, he pushed off slightly with the soles of his feet, jumping upward instantly.

"Screeech—"

At the instant his fingertips contacted the wall, a violent friction force caused his leaping body to freeze for a moment.

Within the thousandth of a second before this slipping tendency could occur, Fang Cheng formed a claw with his right hand, and his arm muscles and waist-abdomen core suddenly exploded.

He was not trying to counteract the downward slide caused by gravity, but was using this powerful friction force as an upward fulcrum.

In the next second, instead of falling, his body rose, actually surging upward along the wall by more than half a meter.

Immediately after, his left hand followed, doing the exact same thing.

Every grab was like a mini Pull-up performed on a vertical plane.

This could no longer be called climbing; it was a completely violent, rapid leaping.

Fang Cheng instantly understood.

The magnitude of friction depends on two factors: the coefficient of friction and the normal force.

He didn't need to move slowly like a gecko.

As long as he could exert a sufficiently large normal force against the wall, he could completely convert this terrifying static friction coefficient, which was increased to 1000%, into upward propulsion.

As long as his speed was fast enough and his power was fierce enough, he would never fall.

Of course, such a violent explosion was not needed right now.

With just two swift alternations, the wall of over three meters high was boldly conquered by Fang Cheng.

His body was already firmly clinging to the seam between the wall and the ceiling.

At this moment, he was like a leopard perched on a cliff, eyeing its prey.

In the next instant, Fang Cheng twisted his waist and lightly kicked his feet against the wall.

His whole body flew toward the center of the living room like a launched cannonball, turning in mid-air.

His arms spread out in the air, lunging toward that upside-down steel forest.

This time, he didn't use his entire palm to grab the iron frame; that would be too unchallenging.

His target was the 90-degree right-angle edge under the iron frame, which was less than one centimeter wide.

At the exact moment his body rose to its highest point, Fang Cheng suddenly reached out his right hand.

Using only his thumb, index, and middle fingers, he precisely pinched that metal edge, which could barely even be called a handhold.

In rock climbing, this is known as the "Pinch Grip", which is the pinch-holding technique.

This technique is very important in rock climbing, especially when facing smooth or small holds, where pinching can provide stable support.

However, Fang Cheng's fingers were currently acting on a death angle where, in the eyes of an ordinary person, an effective load-bearing surface barely existed!

However.

A scene defying the common sense of sports biomechanics occurred.

Fang Cheng's body weight of over 90 kilograms, along with the impact force of leaping forward—all the power converged here.

But his three fingers seemed to have turned into precision calipers made of high-strength alloy, biting onto the edge of the iron frame with a death grip.

His entire body was brought to a steady halt, hanging in mid-air.

Such a right-angled edge, even for the world's top rock climbers, would at most be used as an instantaneous leverage point to adjust posture, and was absolutely impossible to use as a support point for hanging the entire body.

In the past, even if Fang Cheng gripped with all his strength using both hands, he wouldn't have lasted more than a few seconds before losing his hold.

But now, his finger strength, powerful enough to transcend human limits, combined perfectly with the 10-fold increased friction, creating the miraculous scene before his eyes.

Fang Cheng composed himself, and did the same with his other hand, also using the "pinch grip" method to grab the lower end of the iron frame not far ahead.

Then, like an agile giant ape, with arms alternating, he swung forward through this steel forest with amazing style and rhythm.

His movements were relaxed and effortless, his speed getting faster and faster, even carrying a bit of showing-off with plenty of room to spare.

Suddenly, at the instant of a forward swing, Fang Cheng's waist and abdomen suddenly exerted force, twisting him around like a spinning top.

His body instantly leaped high again, completing a swift tucked somersault in the process.

"Thud!"

With a dull thud, Fang Cheng's limbs spread out like a gecko's, and his fingertips and soles firmly "stuck" to the smooth ceiling.

His entire being actually broke free from gravity, hanging upside down in the air in defiance of common sense.

But, this was not the end.

Last time, Fang Cheng had used the inertia of leaping forward to press his back against the ceiling and slide rapidly.

But this time, possessing more initiative, he could completely achieve a level that was previously unattainable.

Fang Cheng maintained this incredible posture, his core strength tensed, feeling the residual forward kinetic energy after the somersault.

Immediately after, his limbs moved alternately, like the evil spirit Kayako from the movie, crawling forward upside down.

But if one observed closely, they could find that he was not truly crawling, but was adopting a gripping method to drive his body forward.

Every time his fingertips and toes pressed against the ceiling, it was like stretching and pushing off on flat ground, and then he would leap forward a short distance.

The 1000% increased friction turned the ceiling—which was only coated with putty powder and already slightly rough—into a runway with traction.

Just like that, relying on the skill effect of "Absolute Control", Fang Cheng wandered and crawled back and forth on the ceiling.

This feeling was incredibly wondrous, as if gravity were distorted, and his entire worldview was overturned at this moment.

Until he crawled near the top edge of the floor-to-ceiling window, feeling his body grow heavier and heavier, and on the verge of falling.

Only then did Fang Cheng choose to stop.

He kicked off the ceiling with both hands and feet at the same time, completing a Xiaosa two-and-a-half rotation twisting flip in mid-air.

Then, he drifted down gently like a falling leaf.

When the soles of his feet landed on the floor, they made almost no sound.

The entire process, from takeoff to landing, was as smooth as flowing water and completed in one breath.

Fang Cheng stood up straight, breathing slightly, but his mind was rapidly replaying every detail from just now.

"After his agility attribute made a Breakthrough past 40 points, my hang time simply keeping my body from falling during free fall was about 3.5 seconds."

"Last time when I obtained the 'Air Walk' special effect and tested it in the living room of my old home, combining front and back flips with sliding actions, I extended the limit of my hang time to 5 seconds."

"But this time..."

Fang Cheng carefully estimated, from the takeoff and swing, to the upside-down crawling on the ceiling, until finally releasing his grip and landing.

The entire hang-time process, without counting the suspension time of the front and back flips, had actually been stretched to nearly 9 seconds!

If fully counted, it had clearly exceeded the 10-second mark.

What an astonishing improvement!

A brilliant light burst from Fang Cheng's eyes.

Although he had not yet mastered true Flight capabilities.

But this extremely abnormal, ultimate clinging ability, coupled with hang-time techniques far exceeding those of ordinary people...

...could completely become an unparalleled means of three-dimensional maneuverability in complex urban environments, a Qinggong movement technique that was almost Xuanhuan.

If this Gecko Wall-Walking Technique had Realm level divisions,

his current self had already reached a Grandmaster Realm worthy of the name.

Fang Cheng did not even have the slightest doubt.

As long as his physical stamina could keep up, he really could freely shuttle through the steel jungle of skyscrapers just like Spider-Man in the movies.

Of course, the body's explosive power and the wall Materials' structure would be a very critical consideration factor.(End of Chapter)
