"Oh mom, who's scolding me?"

Yun Kai in the Longyuan Tiankeng sneezed fiercely.

He doesn't know the prediction skills of Taiyimen, but he can guess the difference with a finger pinch. In addition to his mother, the one who will mutter to him behind his back is either a stingy girl or Queen Xia, or a violent girl like Chen Ziyi......

When he thought of the violent girl, the corner of Yun Kai's mouth showed a hint of a playful smile.

Yan Xiaoyi said that a creature like a woman will not be on the house for three days, and Yunkai has succeeded in cultivating his internal skills this time, and plans to go out and snap the violent girl - he thinks too much, and he only has the courage to beat people up for the time being.

I have to say that the two treasures of Yunkai and Chen Ziyi are indeed a good match, and the slutty man and the tsundere woman are a perfect match. When the two of them had their respective skills soaring, the first thing they thought of was to show off their strength with each other, and then beat them up happily......

But before that, he had to figure out how swollen he could leave the Longyuan Sinkhole. Long Yan and Dashan both rushed out in an extremely windy posture, and he couldn't pull down too much. Although with his current kung fu, there is naturally no problem in climbing out of the Longyuan sinkhole, but if he really wants to go out in this way, he will definitely be despised to death by the iceberg girl......

In the afternoon of the next day, after completing the routine training, the fish head announced the start of the challenge to the Gate of the Abyss.

The rules announced by the fish head are very simple, just rush to the exit with your bare hands, no matter what method or effort. The fish-headed boss himself, who is famous for his martial arts, will take on the role of protection during the challenge, and will not fall to his death even if he falls from the dome - as for whether he will be half-killed by the fishhead pit, this matter is questionable.

The first to play was Long Jiu, Xu Hu, who was good at gecko wall skills. For more than a month, under the hellish training of the fish head boss, everyone's kung fu has made great progress, and Xu Hu's gecko wall swimming skill is no exception.

Under the attention of all the little friends, the thin Long Jiu leaned his back against the cliff, his hands and feet were against the wall, and he walked up flexibly, looking very relaxed-

In "Mission Impossible", Tom once wore a pair of gecko gloves and climbed the world's tallest building, the Burj Khalifa, with his bare hands along the glass wall. This is not science fiction, Yun Kai heard the road madman say that he made that thing more than ten years ago.

In terms of the ability to climb walls, the gecko is definitely a powerful divine beast. A few decades ago, it was thought that geckos had suckers or slime on the soles of their feet, but these assumptions were quickly disproved by experiments – it was clear that if a gecko was attached to a wall by slime or suckers, how could it be able to walk nimbly?

After in-depth research, Lu Maniac found that the soles of the geckos' feet showed brush-like fluff under a high-powered electronic magnifying glass, and the end of each fluff was again divided into hundreds of finer fluffs, and the size of these fluffs was tiny to the nanometer level.

So the question is, what force does the gecko rely on to attach to the wall?

"Lao Tzu can't understand your technical illiteration, you know that there is a force in this world, just van der Waals force." Lu Maniac didn't bother to explain to Yun Kai at the time, and gave a simple example: "The mobile phone screen protector is the ...... that relies on Van der Waals to stick to the screen."

Yun Kai didn't know how to do it, but he only knew that it was an electrostatic interaction between some kind of molecules. The work of geckos swimming in the wall is probably to simulate the electrostatic attraction between the molecules by means of power release, so that people can be attached to the wall like geckos.

Once again, Huaxia martial arts showed its magical side. Just like artemisinin or Yunkai's Xun Yuansu, what scientists have only recently figured out, the ancients learned this trick from geckos using only the simple principle of biomimicry.

When Yunkai was distracted, a tragedy like Brother Tom happened in Long Jiu's shoes - there was no electricity.

He climbed up the cliff, it was easy at first, but the closer he got to the exit, the more difficult it became, because the friction was completely useless, and the palms and soles of his feet had to fully bear his weight, and a few hundred meters from the exit he exhausted his internal strength, and fell down high in an exclamation!

The fish-headed instructor had expected it, and suddenly rose from the ground, grabbed his belt in mid-air, and led it horizontally to the cliff, and stepped on the cliff with his feet for more than a dozen steps before he unloaded the force of his fall, dragging the pale Long Jiu to the ground......

"Emma, scared the baby to death!" Long Ba, who is usually closest to Long Jiu, quipped: "Long Jiu, didn't you say a piece of cake last night?" ”

Long Jiu breathed for a while, then opened his mouth silently: "#¥@%&*......"

"What do you mean?"

The bracelet read Long Jiu's lips and translated cheaply: "YOUCANYOUUP, NOCANNOBB!" ”

You can do it, you can't do it, don't BB.

Everyone couldn't help laughing, even the cold fish-headed boss couldn't help laughing, and it took all his strength to control the shaking of his facial muscles, and shouted: "What's so funny? Whoever laughs is on! ”

A bunch of people were silent, except for the bracelet fluttering up and down in the air, laughing wildly.

The fish-headed boss glanced at it, pointed to the knife and said, "Dragon Eleven, you go!" ”

The knife groaned in pain, and pleaded with a frown: "Fish...... Instructor Yu, I feel that I am still immature, and my kung fu is far from being practiced well, so I am willing to continue to accept the training and guidance of the instructor, and I am not in a hurry to go out......"

"Less of this!" The fish head sneered: "Do you believe that I carried you up and threw you down?" ”

"How embarrassing is that?" The knife said with a bitter face: "I'm on, I'm not good yet!" ”

The pain of the knife was that the instructor did not let him use the dagger.

If he had a pair of daggers in his hands, he could easily get out. But without a dagger, he would have to use the Eagle Claw Gong and use his hands as double daggers - the fish head forced him to stick his fingers into the stone, and Nima didn't let people live?

People are under the eaves and have to go to the ground. The knife climbed up the cliff in a tragic way, and before he even entered the area where the flying tiger was entrenched, he fell down sadly, and the ten fingers of his hands turned into ham sausages again......

The tragedy finally opened the clouds.

Yunkai confidently came out of the ranks. Two days ago, his climbing process was about the same as a knife, but he was impressed by the fact that he didn't even need to use the eagle's claw now, he could climb it with a little friction, and then drag the stalactites of the dome and play gymnastics to easily reach the exit.

As for the group of flying tigers who occupy the mountains as kings, they have no deterrent to him who has poison skills, and he can also probe the enemy situation by the way, and prepare for the watch chain to recover that group of thugs......

It's a pity that the ideal is plump and the reality is skinny. The fish-headed boss knew the details of this group of small pot friends, and said with an evil face: "Dragon Thirteen, you are not allowed to use your hands." Let's go up! ”

"God...... Shenma?! ”

"Don't understand? Do not use your hands. Do you want me to click on the acupoints of your arms first? ”

"No, no! I must follow the instructor's instructions and say that if I don't do it, I won't do it......"

Yunkai was killed by the fish's head, but he didn't dare to refute a word.

The story of the past month shows that the result of the dispute with the fish head will inevitably lead to the abyss of despair, with unpredictable consequences - for example, the fish head will even point the acupoints of his hands and legs, and then force him to climb up with a leather whip.

Regarding the shameful behavior of the fish head boss without discipline and no lower limit, Yunkai just wants to use Li Shutong's farewell poem to evaluate: outside the long pavilion, by the ancient road, and in the grass sky.

It's all tears, you know.

Yun Kai sighed and stood depressedly under the cliff.

Pit daddy, it is forbidden to use hands to climb rocks, can it still be called rock climbing? Obviously not, he can only be called Dengyan, but the fish-headed boss gave him such a problem.

Yun Kai carefully pondered the twelve forms of the dragon body. Deer, horses, cows, tigers, bears, apes, the shape of these four-legged creatures, you don't have to think about giving up directly; To climb the cliff in the snake body method, you probably have to learn Long Jiu's gecko wall swimming skill first; He is still confused now, and he doesn't think about it for the time being, and the only ones left are eagles, swallows, harriers, and cranes to choose from-

Harrier-shaped, only harrier-shaped.

The flexible harrier shape is the best choice for the immediate environment. Yun Kai had a plan in his heart, took a deep breath after taking a step back, his legs quickly exerted force, his body turned into a phantom, and shot towards the cliff at high speed!

Under the intently gaze of his friends, when he was about to hit the cliff at high speed, his upper body suddenly leaned back, and his legs stepped on the cliff horizontally, and his speed did not decrease but increased, accelerating towards the dome!

Mercedes-Benz, who is keen on drag racing, has a lot of treasures for famous cars all over the world. He was dumbfounded to find that Yunkai's acceleration time of 100 kilometers was less than two seconds, which was better than most of the top supercars!

What's even more speechless is that Yunkai is not running on flat ground, but on an inverted arc cliff!

Like a motorcyclist's acrobatic performance, as long as the centrifugal force generated by the speed is greater than the gravitational force, it can reciprocate on a circular track perpendicular to the ground - this does not violate the principles of physics, but the diameter of the Longyuan sinkhole is too large, and the requirements for speed are too high, and few people can do it.

Mercedes-Benz Dan thought bitterly, if Yunkai went to participate in parkour, would David Bell commit suicide in shame?

Yun Kai's own feeling was that he was not running, but flying. It was a great feeling to defy gravity, his arms stretched out like wings, the sound of the wind whistling in his ears, and his body hanging upside down in the air as if walking on ethereal clouds......

The speed can't keep up with gravity, and there is a faint tendency to fall. He suddenly let out a long roar from his mouth, his palms danced like the wind, his body turned over in the air, turned three hundred and sixty degrees in the air, and when he fell to the cliff again, he retreated a little, his body bent back into a ring, and his forward posture changed from running to wheel-like rolling!

The little friends below leaned their necks and swallowed their saliva fiercely. People are more popular than people, and everyone can't climb up the upside-down cliff, this thing just ran up directly, Nima hasn't used his hands yet, he didn't use his hands, dear!

The sharp-eyed knife vaguely found that between Yun Kai's palms, there seemed to be red and blue lights flickering, but he didn't understand that it was Shenma Dongdong. He thought suspiciously, could it be that Yunkai had become Nezha's invincible Hot Wheels?

Pretending to be forced, pretending to be too forced!

Yunkai finally rushed to the stalactite area, his legs were skillfully hinged on the stalactite, and the upside-down golden hook was hung in the air, and then he flicked forward by inertia, and the person turned over in mid-air, and his legs hung on another protruding stalactite, and he pushed forward like an ape......

At this time, Yun Kai was sure that he could really break through the gate of the abyss without using his hands!

The bracelet flapped its wings and followed Yunkai not far away. When it saw that its master could fly to the dome without wings, its eyes were full of admiration and longing for love, and it muttered flatteringly: "Yunkai, take me to pretend to fly, take me to fly, take me to pretend to fly!" ”

"Shh Yun Kai hung on the stalactites and sat on the gesture, pointed to the flying tiger's nest not far away, lowered his voice and said, "Let's observe first, and then go back and get a trap for catching birds......"

"You're wrong," corrected the bracelet with a dark face, "Cousin, I'm the birds, they're not!" ”

“……”

When a man and a bird were muttering on the dome, the fish-headed boss in the ground didn't say a word, but his arrogant eyes had already sold his pride cleanly.
