Perhaps because of the rainy season, it rained for several days.

There were three pairs of footprints walking across the misty road one after another, but there was not a single splash of water where they walked.

He was not wearing a red and white raincoat like the other two ladies, but his plain white robe and a pair of white boots were not stained with the slightest trace of water.

Led by Kazeka Koyuki, Miami and Terumi are heading to the machine factory jointly built by the two countries, and since the concept of "factory" was proposed at the Ninja World Council, there are now several modern machine factories that have sprung up from the ground, and each factory has an endless line of glossy black railroad tracks at the entrance.

The site of the factory was also located in the southernmost part of the Fire Mansion, southwest of the Fog Capital, which originally belonged to the former Vortex Country.

Looking at the building park surrounded by steel, as well as several large chimneys that stood rough and upright, he only felt trance and unreality, although he also knew that the ninja world actually had a good technology, but when he faced this kind of building that looked like an industrial park in his previous life, it was still a little inconsistent.

"How many workers are there? What is produced? ”

Mianma glanced at the chimney that was emitting white steam, pointed to the factory below, and asked the princess of the Snow Country, who was wearing a smart overalls with a high ponytail next to her.

"This is the production factory of Chakra armor, you will be able to see the finished product later, and there are more than 3,000 workers."

Speaking of workers, Fenghua Xiaoxue complained with an exaggerated expression:

"You vortex country is really too rich, not to mention the food and shelter of the workers, the salary is still three times that of others, those craftsmen and people with some production experience flocked to it after hearing it.

"I suspect that the ordinary craftsmen of the Craftsman Country and the Iron Nation have all mixed in with us."

Fenghua Xiaoxue's tone changed as she spoke, and she said with a smile:

"But with the addition of these craftsmen, the improvement of our technology is undoubtedly huge, two adults, please."

She made a gesture of please, and walked into the factory behind Mi Ma and Terumi.

The expected roar of machinery did not penetrate the eardrums, but instead appeared in stacks of white vortex country uniforms stacked into small mountains, most of which were black-edged and white-robed.

There are a couple of overalls people sorting and packing these uniforms.

Fenghua Xiaoxue walked to a corner of the warehouse, picked up a black-edged white robe on the top floor, and said:

"After my research with the craftsmen of the mechanical group, this is the culmination of our current mass-produced chakra armor, and there may be changes in the future, but the difference will not be too big. We call this the Vortex Suit (1) type. ”

Zhao Meiming took the black-edged white robe handed over by Fenghua Xiaoxue, and a silk-like texture immediately passed into her brain through her fingertips, Zhao Meiming suppressed the admiration in her heart, and asked in a deep voice:

"What's this material? How do I kick up Ninja? ”

Fenghua Xiaoxue casually picked up a black-edged white robe and draped it on her body and said:

"We compared countless materials provided by Misa-sama, and finally agreed that the silk of Nanao-sa was the best clothing material, and the one in Hades-sama's hand was made of its silk."

Seeing Ma looked at himself with a little appreciation, Fenghua Xiaoxue brushed the broken hair around her ears, and said seriously:

"Because it is a material made with the participation of tailed beasts, it has excellent chakra conduction characteristics, and with the chakra warehouse sealing technique and the armor technology of the wind and the furious waves given by Lord Ma above, wearing this dress is actually equivalent to equipping one, um... Inferior tailed beasts.

"Hades-sama can try to inject chakra into your clothes."

Terumi listened and slowly injected her chakra into it, and the black-edged white robe in her hand took the lead in emitting a cloud of fluorescence, but soon returned to calm. She perused the connection between her and her clothes, and spoke:

"It probably has the upper limit of the upper ninja chakra, and there should not be much difference between it and Kakashi's chakra, and there should be a lot of sealing techniques engraved in it."

As she spoke, she also flipped the clothes in her hand to the inside, and sure enough, she could see that there were dense techniques inside.

Seeing this, the face numb also stepped forward and took a closer look:

"In addition to the chakra storehouse's techniques, there are also 5 basic ninjutsu techniques with different attributes engraved on them."

He pointed to what at first glance looked like ghostly drawings and explained:

"This is the technique of 'Wind Escape, Great Breakthrough', 'Thunder Escape, Earth Walking', 'Earth Escape, Earth Flow Wall', 'Fire Escape, Hao Fireball Technique', and 'Water Escape: Waterfall Technique'.

"I think the ninja should be able to release the right amount of chakra to fill in the different techniques, so as to release the corresponding ninjutsu."

Mian Ma said and casually filled the chakra into the technique of "Tu Dun Tuliu Wall", and after a bang, Mian Ma found that the earth wall actually rose from the feet of Fenghua Xiaoxue.

Fenghua Xiaoxue jumped down from the earthen wall with a backward flip, looked at the frowning look on her face and smiled bitterly:

"Adults should know, although this vision is very good, but according to the testers of the Fire Mansion, it takes superb chakra control to release ninjutsu in this way, otherwise the ninjutsu released will be against friends and enemies."

Mian Ma nodded, touched his chin and thought for a while before speaking:

"It's a great idea! It can be retained, as for the size of Chakra's control, this release is indeed stronger than the control required for a simple release, but it is better not to seal and can be taken by surprise. ”

Terumi on the side also added:

"If you use this training a lot, it will also help them improve their control, but how long these techniques can be maintained is a question."

"About 200 releases, I guess I'm right. Little Snow Princess. ”

Mian Ma sensed it, and said to Fenghua Xiaoxue with a smile.

"What the Lord said is very right, and this is still an ideal situation, in fact, after 170 times, it will be more difficult to achieve the release of ninjutsu because of the need for higher chakra control, and the 190 or so spells will be completely worn out."

After listening to Fenghua Xiaoxue's explanation, Mian Ma nodded in agreement, and then turned his gaze to the action of Terumi pulling the uniform.

Terumi pulled her uniform hard in the opposite direction, but the clothes did not show the slightest deformation, and she finally couldn't resist her curiosity and asked Fenghua Xiaoxue:

"How's the defense of this Vortex suit?"

"It's made of the silk of the Seven Tails, and it's absolutely defensive, and we and the testers can't damage it at the moment...

"Lady !! Masa"

"Woo~"

The fingertips of the face numb slid over the white robe in Terumi Ming's hand, and a crack also appeared, and soon the white robe was split in half under the sliding of the fingertips of the face numb.
