This wool ball is not an ordinary wool ball.

First, the hair that wools grows rapidly under the catalysis of chakra. If the chakra is exquisitely controlled to stimulate the division of root cells, the organic molecular structure that forms the hair can also be specially designed.

Naruto's hair adopts a imitation carbon nanotube structure. The tensile strength of the carbon nanotube reaches 50~200gpa, one hundred times that of steel. Its elastic modulus can reach 1tpa, which is equivalent to that of diamond, about 5 times that of steel.

The carbon nanotube center leaves a hole for the flow of chakra to ensure that the special physical properties of chakra particles are blessed on every organic molecule, further increasing the toughness of the hair.

Ordinary hair grown by Jilaiya can be as hard as steel after being infused with chakra. How tough will hair be when it is extremely effective in using chakra's nanotube channel?

It is no longer possible to use the substances that exist in the real world to compare them. It can only be said that both hardness and toughness have reached an incredible state!

By rationally using the principles of molecular mechanics, the hair that Naruto used to weave wool balls is the toughest hair in the ninja world, and even the god-nothing hair of Otsutsuki may not be comparable.

Secondly, the hair structure of the braided wool ball also conforms to the basic mechanical principles. It is a structural force analysis diagram digitally simulated by supercomputers and then the optimal force structure calculated by precision can perfectly remove all external forces applied to the surface of the sphere.

Structural stress analysis is often used in the architectural design industry to design bridges and skyscrapers. In addition to calculating the bearing capacity of large buildings, it also needs to calculate wind resistance, internal stress and elastic stress and other elements.

Just like the weaving technology of Kevlar bulletproof vest, the factors that affect the knitting method of Kevlar fibers on force leakage are fully taken into account. The weaving technology that forms the surface of the wool ball, ensuring that when subjected to strong external force, each hair fiber can be uniformly subjected to force on the surface area of ​​the stress when subjected to strong external force.

The contents of the hair that supports the surface of the sphere are also a three-dimensional honeycomb mesh structure similar to the best bridge stress structure, which can absorb external impacts to the maximum extent.

Finally, the surface of the sphere is not smooth. The specially designed wavy miniature patterns are like diversion dams, which can split the air waves impacting on it into small turbulences, and resolve the shear force of the wind blade hitting the surface of the sphere into invisible.

In addition, overall, the big wool ball is like a tumbleweed, not only fluffy, but also rolls around.

Neji first slapped sixty-four palms, and when he slapped the ball on the hair ball, he bounced the palm force back, and the wind blade cut it up and instantly disintegrated. Finally, he angrily used the Konoha Dragon God. The tornado hit it and only made the hair ball bounce everywhere. The wind blade cut off a lot of hair, but he couldn't resist Naruto's input chakra to control the hair root cells to split wildly, and the cut hair had not yet grown much.

The Eight Gate Dunjia was activated, and Ningci's speed exceeded the speed of sound, and his physical skills were at its peak, approaching perfection, and he understood the artistic conception of Tai Chi "circular". He several times in the ninja world. From the perspective of physical skills, no one except Xiao Li was his opponent.

It’s a pity that his opponent is not a human at all, but a ball, and he can’t even use any extraordinary physical skills.

The golden hair ball can not only be passively defended, but as long as Neji approaches, sharp hair spikes will suddenly pierce out, and the hair will pierce the skin by the hair. The hair will drill into the human body like a living bug, destroying the human body from the inside, with strange and fierce lethality.

The more he beat Neji, the more depressed he felt, he felt that he had no idea how to start and wasted a lot of chakra. He simply stopped for the time being, no longer blindly attacked, and confronted the big ball.

At this time, the simulated battlefield in the center of the stadium had been ruined in the crazy attack of Neji just now.

The ground was full of vertical and horizontal ravines cut by wind blades, and there was a large pit exploded by a tornado in the center of the site. Originally, Captain Yamato used wood escape to plant several trees on the battlefield, but now the big trees have been cut into log sections.

The ninjas from all villages watching the battle were all ashamed, dumbfounded, as if they had seen a ghost.

The Konoha Ninja is fine, but both of them are Konoha Gumnja on the field. The stronger they perform, the more relieved they are. The ninjas in other villages can't help but start to reevaluate the strength of Konoha Village.

"Is Konoha's Shinin a monster?" a ninja from the Sand Village murmured.

"The strength of that boy from the Hinata clan is indeed at the level of the movie. The information on the second round of the Chunin Exam is accurate!"

"Naruto Uzumaki, who fought against him, was not simple either. He had been with the fierce attack of the Shadow-level physical ninja. Isn't it that he had just graduated from Ninja School and his graduation grades were also average?"

"Didn't you receive new news? The Kusin Village camp was destroyed by him alone, and twelve Kusin were injured, saying that it was to steal the woman..."

"Oh? I need to write down this article. Go back to the village to discuss it with the leader. Choose the best female ninjas in the village and try to use the beauty trick to counter him."

"A good idea. I will report to Lord Tuying when I go back to the village. Lord Tuying has a beautiful granddaughter..."

...

The out-of-village ninjas in the audience were talking, and the confrontation between the people and one ball in the center of the venue began the second round of the fight.

"Naruto, you coward, your head-shrinking turtle!"

Neji tried to make two more moves, and the big fur ball kept swaying, but it had no killing effect on Naruto hiding in it. He was so angry that he sarcastically said: "Is this what you said to face a shadow-level ninja? It's just like an armadillo, and he was beaten passively with his thick hair! I may not be able to kill you, but as long as you throw you out of the duel arena, you will lose!"

A muffled voice came from the hairball: "Hmph, do you think the ninjutsu I developed specifically for you is nothing more than that?"

As he said that, the hair ball suddenly stretched out many hair tentacles. From a distance, it looked like a big sea urchin. The tentacles climbed the ground, just like the hair ball had countless feet. The hair tentacle suddenly bounced, bounced the big ball up, smashed it at Neji, and actually started to take the initiative.

The tentacles woven from the hair each perform their duties. Some tentacles tangled towards Neji like pythons, restricting his high-speed movement. Some tentacles separated from each other and condensed blue spiral light balls in the center of the bifurcation. They rubbed the spiral balls with their hair in a fancy way, and waited for Neji to be entangled, and the spiral balls that were rubbed were about to hit him.

Neji quickly flew away, and the ball was chasing him reluctantly under the tentacles' support. The ground was beaten so dusty that it was flying, and its movement speed was not slow, sticking to Neji like a maggot on his tarsal bone.

Neji was so uncomfortable. Since he graduated from Metro's training, he has never been so embarrassed. He just felt that he was not fighting with others, but fighting a weird tentacle monster.

Fortunately, Naruto's hair was golden, and the changed big hair ball looked a little cute. Many girls watching the game screamed "Kawaii, Wakai".

If you change to other colors, such as black or brown, it will look very disgusting. The degree of ugliness is comparable to the secret technique of "Di Jin Yu" in the horn.

In fact, the lion's mane technique is not a real absolute defense. Fire escape ninjutsu has great restraint on the hair ninjutsu. If Neji seizes the opportunity to use powerful fire escape, he can burn most of his hair with one fire.

In order to absorb kinetic energy, there are many gaps between the hair strands, which cannot completely block the air. Using highly toxic gas can also kill Naruto hiding in the center of the hair strand.

But the problem is that Neji is neither poison nor good at fire escape. Whether it is Hinata Soft Fist or Nando Water Bird Fist, they are physical techniques created to destroy the human body. There is no trick to attack a big hairball in the secret letter of Hinata Boxing and Nando Water Bird Fist.

Hyuga Neji also understood the artistic conception of Tai Chi, but unfortunately Naruto was more harmonious than him, and they all turned into a big ball. If he compared the ball, he probably couldn't compare with anyone who was more round.

Neji's wind blade and soft fist are ineffective against the wool ball. It is not that easy for the wool ball to wrap around Neji with tentacles. Whenever he wants to succeed, Neji will use the wool ball to blow away.

One man and one goal scored each other for a round, and found that no one could do anything to each other. The remaining game entered garbage time, and it would take a long time to end if one of them had chakra.

Neji was trained by Metero to develop a bodybuilding muscle and excellent physical strength. Naruto was born with energetic and full of vitality. If he was exhausted, he would really have to waste his energy and would not have any results until dark.

Sarutobi Hiruzen also saw that the two of them had entered the stage of attrition, and it was meaningless to continue to entangle, so they stopped this round of duel in the name of Naruto and decided that the two sides would tie.

Naruto calmly accepted the ruling of the draw. After all, the Chunin exam is not a practical battle. In actual combat, he can use the scientific ninja tools freely. At that time, the attack methods will be more diverse. Even if his opponent Shi Ningji is like his physical skills master, he will inevitably be hit.

For example, installing a high-energy battery inside the wool ball to energize the carbon nanotubes and a high-voltage electric hair whip can generate the high-temperature cutting force of the signature weapon electric whip of Iron Man's mortal enemy, Sandai.

For example, if a high-circular wave generator is installed for high-frequency oscillation, a hair that reaches a high-circular wave oscillation frequency will have the sharpness of iron-cut like mud. At that time, a hundred thousand hairs will be 100,000 magic weapons and weapons, and they can wield everything close to it.

...

Neji was very unwilling to give up, and was so angry that his eyes were full of blue veins, deeply annoyed that he could not teach the scumbag a lesson for Hinata's sister. But when he thought about it carefully, this fuzzy method was really his nemesis. Not only was his physical skills and soft fist restrained, but he could not even see through the inside of the fuzzy.

After opening the white eyes to observe, the chakra meridians looked white, and every hair of the braided wool ball was filled with chakra. When the white eyes were turned, they could only see the white area, and they could not see through the inside of the large ball woven by the chakra.

After Naruto and Neji stared at each other and left the battlefield, the ninjas in the spectator room started to talk again.

"In this Chunin Examination, there are many people who have advanced to the third round of the fight. I thought there was a dark story, but it was Konoha's secret operation. Now it seems that the quality of Konoha's Shinoha is indeed extraordinary!"

"Are the two people who fought against me just now really the ninja? In the war a long time ago, I didn't fight with Konoha Kanin. Why do I feel that Konoha Kanin is not as powerful as them?"

"The Chunin Examination is actually a microcosm of the ninja war. Judging from the performance of Konoha Shizunin now, in a few years, this year's Xiaonin will grow up to become the backbone of Konoha. The other four major ninja villages join forces, and it is not necessarily Konoha's opponent!"

"Koha's economic strength is increasing day by day. Continue to watch their ninja grow. Will Koha be the only one in the entire ninja world in the future? Do we obediently surrender to Koha?"

"Idiot, be careful, go back to the village and talk to the village leaders, don't reveal hostility here!"
