Looking at the "Absolute Control" special effects introduction displayed on Panel, a hint of understanding flashed in Fang Cheng's eyes.
From the perspective of sports mechanics, this Pull-Ups training is one of the most extreme exercises for grip strength.
It requires the trainer to firmly hold the support with his fingers and rely on the concentric contraction and Eccentric Contraction strength of the forearm muscles to resist his own gravity.
This process will deeply stimulate the flexor and extensor muscles of the forearm, and even the core muscles of the hand such as the palmaris longus.
In the dynamic stage of practicing Pull-Ups, that is, when the body is pulled upward, the fingers and palms must actively tighten to produce explosive grip strength to Gravity Defiance.
In the static hanging stage, the hands need to continue to perform Isometric Contraction in order to maintain body stability, which also exercises the durability of the grip strength.
Ordinary people cannot do a few Pull-Ups. In addition to factors such as weak back muscles, excessive weight, and incorrect Exert Force techniques, it is also directly related to the lack of endurance and explosive Exert Force in the forearm muscles.
Often the hand loses strength first, but the back muscles have not yet reached their limit.
Therefore, many top rock climbers have fingers as strong as iron pincers.
They regard practicing Pull-Ups and its various variations as the core method of developing grip strength, even more important than back training.
After long-term exercise, the grip strength of the hand can be significantly improved, reaching more than twice that of ordinary people.
Now that I have transferred the skill "Pull-Ups" to Grandmaster Level, it is completely reasonable to be able to derive such overbearing special effects.
Suddenly, Fang Cheng couldn't wait to experience it for himself.
He quickly walked to the wall and picked up a brand new 20kg dumbbell in the corner.
The five fingers grasped and closed, and slowly wrapped around the cold knurled grip of the dumbbell.
The rough metal touch came through the skin of the palm extremely clearly.
Fang Cheng did not deliberately Exert Force, he just stood naturally and held it tightly as he usually does when picking up heavy objects.
The next second, Fang Cheng's eyes narrowed and his body shook slightly.
The power is instantly transmitted from the core along the spine to the shoulders and back, and then pumped into the arms instantly like a high-pressure pump.
Then, the forearm muscles suddenly stretched, and the knotted muscle lines were like twisted steel cables.
All the power passes through the flexor and synergistic muscle groups and converges on the fingertips of the five fingers in a thousandth of an instant!
"Creak--squeak--"
A spine-chilling metal twisting scream suddenly sounded in the quiet room.
It didn't feel like metal being squeezed, but more like a piece of wet wood being squeezed out of the water with great force.
Fang Cheng took a breath, slowly loosened his fingers, and looked intently.
On the hard cast iron grip of the dumbbell, five light white fingerprints were faintly visible, as if they were branded on it.
It flashes out the unique pale luster of metal when its molecular structure is destroyed after being violently bent.
The naked eye estimates that the depth of this depression is at least half a millimeter!
"Hiss... this is a bit outrageous."
Fang Cheng murmured to himself.
Such solid cast iron seems to be a toy that can be manipulated at will in his hands.
You must know that in order to achieve fine operations, the evolution direction of human fingers is that flexibility is much higher than pure strength.
The muscle group involved in grasping Exert Force is a relatively weak link among the muscles in the body.
Generally speaking, an adult's ultimate grip strength is only about one-fifth to one-tenth of the impact force produced by a full-strength punch.
With Fang Cheng now close to 50 points and Strength Attribute, even without using the special effect increase of "Qilin Arm", a simple Straight Punch can still make a clear fist mark on the iron plate.
But that is the result of the whole body's strength being transmitted through kinetic energy and concentrated on the edge of the fist.
If you want to use five fingers with a relatively fragile structure and more isolated Exert Force muscle groups to pinch out a mark on cast iron of the same hardness, the difficulty increases exponentially.
Just relying on Base Strength Attribute, which is close to 50 points, to achieve such an effect is tantamount to wishful thinking.
And now, "Absolute Control", this Skill Special Effect, roughly increases the instant burst of grip strength by 1.5 times.
Only then did I barely touch the threshold of "if your fingertips get cold, you can divide the gold and break the iron" in martial arts novels.
"It seems that with the steady improvement of Strength Attribute, it is not out of reach to simply pinch the Rebar iron rod with five fingers..."
Fang Cheng looked at the slightly deformed 20kg dumbbell in his hand and secretly felt happy.
Fortunately, the degree of deformation is not too exaggerated.
Otherwise, it would be a bit troublesome to deal with such a thing.
After putting down the ravaged dumbbells, Fang Cheng gently shook his hand and focused his eyes on Panel again.
Look at the second special effects content introduction about "Absolute Control".
"Specialization of climbing ability, friction per unit area of fingertips increased by 1000%..."
Fang Cheng read in a low voice, with a trace of curiosity flashing in his eyes.
After thinking about it, I took off the Barbell weight-bearing piece from my waist and threw it on the floor, making a "clang" sound.
Then he moved his muscles, walked to the wall, stretched out his fingers, and gently touched the wall painted with light blue latex paint.
Zizzizi--
As soon as the fingertips came into contact with the wall, there was a strange sticking feeling, which was instantly transmitted from the nerve endings.
It feels as if billions of nano-scale bristles have grown on the fingertips, latching onto tiny pores in the wall that are invisible to the naked eye.
Through internal vision, Fang Cheng can clearly feel that the moment his fingers touch the wall, a strong electrostatic adsorption force is generated at the microscopic level.
The latex paint wall, which was originally as smooth as a mirror, actually became as rough as 800-grit sandpaper under this touch.
"Do you want me to evolve into a gecko?"
Fang Cheng complained in his heart, and simply stretched out his hands, with his fingers spread like claws, and pressed them against the wall.
Try to just grab the wall with both hands and imitate a gecko crawling up slowly.
However, as soon as he Exert Force, his body was slightly raised by less than one centimeter.
Poof!
There was a slipping feeling at the fingertips with no place to apply force.
"No..."
Fang Cheng shook his head.
The job of decorating Master was really great.
As a result, the wall surface is too flat and smooth, with no visible bulges at all.
Pure static friction is not enough to allow him to resist his own gravity at a slow speed on an absolutely vertical plane.
However, just because you can't crawl slowly doesn't mean you can't conquer this wall.
Fang Cheng looked up at the wall about three meters high and the ceiling with putty powder on the top.
There, I-beams reinforced for hanging Sandbag and training equipment are criss-crossed, like an upside-down steel forest.
The "branches" among them provide excellent gripping points.
Fang Cheng stared slightly, then stood close to the wall again, with his legs slightly bent.
Suddenly, he took a deep breath, raised his right hand, and grabbed the wall painted with latex paint.
At the same time, he stepped slightly with the soles of his feet, and his whole body jumped upwards.
Zila--
The moment his fingertips came into contact with the wall, a violent friction force caused his jumping body to freeze for a moment.
In the thousandth of a second before the slippage was about to occur, Fang Cheng's right hand was 50% clawed, and his arm muscles, waist and abdominal core suddenly exploded.
He is not preparing for the decline caused by Gravity Defiance, but is using this strong friction as an upward fulcrum.
The next second, his body rose instead of falling, and actually jumped up more than half a meter along the wall.
Then, follow up with your left hand and do the same thing.
Each grab is like a small Pull-Ups on a vertical plane.
This can no longer be called crawling, but a completely violent flight.
Fang Cheng understood instantly.
The magnitude of friction depends on two factors: friction coefficient and positive pressure.
He doesn't need to move slowly like a gecko.
As long as enough positive pressure can be applied to the wall, this can be increased to a terrifying static friction coefficient of 1000%, completely transforming it into upward propulsion.
As long as the speed is fast enough and the force is strong enough, he will never fall.
Of course, there is no need for such a violent outburst now.
In just two quick turns, the wall more than three meters high was conquered by Fang Cheng.
The body has been firmly clinging to the joint between the wall and the ceiling.
At this moment, he was like a cheetah sitting on Cliff, peeping at its prey.
The next moment, Fang Cheng twisted his waist and kicked his feet lightly on the wall.
The whole person was like a thrown cannonball, turning around and flying towards the center of Living Room.
Stretching his arms in the air, he pounced towards the hanging steel forest.
This time, he didn't use his whole hand to grasp the iron frame, which was too unchallenging.
His target was the 90-degree right-angled edge less than one centimeter wide below the iron frame.
The moment his body reached its highest point, Fang Cheng suddenly stretched out his right hand.
Using only his thumb, Index Finger, and middle finger, he accurately pinched the metal edge that could hardly be called a grasping point.
In rock climbing, this is called "Pinch Grip", which is the pinch grip technique.
This technique is very important in rock climbing, especially when facing some smooth or small fulcrums, the pinch grip can provide stable support.
It's just that Fang Cheng's finger, now acting on it in the eyes of an ordinary person, has almost no effective force-bearing surface death angle!
However.
A scene that goes against the common sense of motion mechanics happened.
Fang Cheng's body weight of over 90 kilograms, together with the impact of the forward leap, all the power is concentrated here.
But his three fingers seemed to have turned into Precision Caliper made of High-Strength Alloy, biting tightly on the edge of the iron frame.
The whole person just stopped steadily and hung in mid-air.
Even the world's top rock climbers use this right-angled edge as a momentary point of leverage to adjust their posture, and never as a support point for full-body suspension.
In the past, even if Fang Cheng was grasped with both hands, it would not last more than a few seconds before being released.
But now, the Finger Strength, which is so powerful that it exceeds the limits of human beings, and the friction that has been increased by 10 times, are perfectly combined to create this miraculous sight.
Fang Cheng calmed down and followed the same example with the other hand, using the same "pinching and grasping" method to grab the lower end of the iron frame not far in front.
Then, like a dexterous giant ape, he alternated his arms and swung forward through the steel forest in an astonishing way and rhythm.
The movements are easy and freehand, the speed is getting faster and faster, and there is even a sense of skill and skill.
Suddenly, in the moment of a forward swing, Fang Cheng's waist and abdomen suddenly turned Exert Force like a top.
The body immediately jumped up high again, taking advantage of the situation to complete a swift Tucked Somersault.
Snap!
With a muffled sound, Fang Cheng's limbs spread out like a gecko, and the fingertips and soles of his hands were firmly "glued" to the smooth ceiling.
His whole body actually broke free Geocentric Gravity and hung upside down in the air contrary to common sense.
But, this is not the end.
Last time, Fang Cheng used the inertia of its forward leap to press its back against the ceiling and slide rapidly.
But this time, with more initiative, he can achieve a level that was difficult to achieve before.
Fang Cheng maintained this incredible posture, tightening his core strength and feeling the residual forward momentum after the somersault.
Immediately afterwards, his limbs moved alternately, like Evil Spirit Kayako in the movie, hanging upside down and crawling forward.
But if you observe carefully, you can see that he is not really crawling, but is using a grasping method to move his body forward.
Every time the fingertips and toes press on the ceiling, it is like stretching and stepping on the flat ground, and then the person jumps forward a short distance.
That increased the friction by 1000%, turning the already slightly rough ceiling with only putty powder into a grippy runway.
In this way, Fang Cheng relied on the skill effect of "Absolute Mastery" to wander back and forth and crawl on the ceiling.
This feeling is extremely wonderful, as if gravity has been distorted and the entire worldview has been subverted at this moment.
Until I crawled to the top edge of the floor-to-ceiling window, I felt my body getting heavier and heavier, and was about to collapse.
Fang Cheng just chose to stop.
He kicked his hands and feet on the ceiling at the same time, completing a Xiaosa and Twisting Dive Two and a Half movement in the air.
Then, it fell gently like fallen leaves.
When the soles of his feet landed on the floor, they made almost no sound.
The whole process, from take-off to landing, was done smoothly and smoothly.
Fang Cheng stood up straight and panted slightly, but his mind was rapidly replaying every detail of what had just happened.
"After Agility Attribute broke through 40 points, during the Free Fall process, it took me Airtime to simply keep my body from falling for about 3.5 seconds."
"The last time I got the "Air Walking" special effect, when I was testing it in my hometown Living Room, I combined the former Backflip with the sliding action to extend the Airtime limit to 5 seconds."
"And this time..."
Fang Cheng calculated carefully, starting from jumping and swinging, then crawling upside down on the ceiling, until finally letting go and landing.
The entire process of staying in the air, without counting the stagnation time before Backflip, actually stretched to nearly 9 seconds!
If fully counted, it is obviously more than 10 seconds Major Milestone.
What an amazing improvement!
Fang Cheng's eyes were filled with light.
Although the real Flight Ability has not yet been mastered.
But this kind of abnormal extreme climbing ability is combined with aerial skills that are far beyond ordinary people.
In the complex urban environment, it can become an unparalleled Omni-Directional Mobility method, an almost fantasy Lightness Skill movement technique.
If this door Wall Gecko Travel Skill, there are realm levels.
Now I have reached the true Grandmaster state.
Fang Cheng doesn't even have a doubt.
As long as your physical fitness keeps up, you can really shuttle freely through the steel jungle of Skyscrapers like Spider-Man in the movie.
Of course, the body's explosion Exert Force and the wall material structure will be a very key consideration.
