The training ground of the ninja warrior legion is in the territory of the land of the land and the original iron country, and the part of the territory that is now part of the earth country.

100,000 people were recruited, and the placement of these 100,000 people was an important task. The engineering troops of the Land and the Land have restored part of the original appearance of the Iron Country, the sword dojo, the city walls, and the wooden buildings full of classical style, which are the houses of the ninja warrior army.

Obiji, who was sent by Uehara to study with Mifune, was called back by Uehara, and after so much time, the immature boy has become much calmer.

There was a long scar with a knife and the corner of his forehead spread straight to the left side of his face, looking a little hideous.

"How did this happen?" Uehara frowned and asked with concern.

"I used my ninja knife to chop a rock, and the blade broke and hurt." With a knife said indifferently.

“？ The quality of your ninja sword seems to be too poor, right? ”

"That day I split thousands of solid stones, and nine of my ninja swords broke." The expression with the knife is still indifferent.

Although he didn't talk too much about anything else, Uehara was convinced that Obitome had grown enough with Mifune.

It is impossible for 100,000 ninja warriors to train in the same training ground, they are divided into large and small dojos to practice.

The first stage is naturally the most ordinary swordsmanship cultivation, and it is not too simple for the ninja world to find people who are proficient in swordsmanship. The dojo was full of people with wooden knives chopping stakes, the members of the Ninja Legion were from a complex background, most of them were adults, and as for the younger and more malleable teenagers, they had a better place to go and generally go to the ninja school in any ninja village of the Ninja Alliance to study.

The second stage of the training of the Ninja Legion is shuriken technique, and the ninjas of the Wind Demon clan who are good at shuriken skills teach the samurai clan shuriken skills, although it will not let everyone have superb shuriken skills like the wind demon clan, but it will not be too bad, at least it can suppress the white absolute who does not have too many means of attack.

Then the second stage was completed, and all that remained was the operation of the ninja equipment, as well as the flying wings and other special ninja equipment, and finally the joint operation.

Along the way, Uehara suddenly stopped, and said to the belt knife that followed him closely, "If you let an ordinary person train to become a qualified samurai, how long will it take?" ”

Beltknife frowned, "Many years." ”

“…… I mean, you don't need to be too powerful, you just need to be able to borrow the ninja to achieve the combat power of ordinary shinobi. ”

"Three years." Bringing a knife is a professional, as one of the few people in the original book who can rely on themselves to get rid of the reincarnation of the filthy earth, the others who get rid of the reincarnation of the filthy earth are all powerful ninjas, only the sword is just a samurai, and this guy's talent is by no means worse than Mifune.

"Three years." Uehara nodded, which means that the Ninja Alliance can cultivate 100,000 ninja-level combat power every three years.

"With a sword, I'm going to hand over the ninja warrior legion to you." Uehara said with a smile.

There is no one more suitable person than to carry a knife, and Mifune is also a suitable person, but Mifune's physical condition is not good right now.

What kind of behemoth the Ninja Warrior Legion is, with a knife clearly understood, when he heard that he was going to hand over the ninja warrior legion to himself, he looked surprised.

"I'm not going to disappoint Uehara-sama." With a knife and a little excited, he knelt down on one knee.

——

The City of Peace, which hovers in the sky all day long, is almost on the verge of becoming an independent ecosystem as the air fortress continues to improve, becoming less and less dependent on the ground.

Uehara wants to see Master Harumi, but is told by the craftsmen that Harumi is conducting a key experiment, and everything can only be done when he comes out.

Uehara waited for almost a week.

"I'm sorry to wait, Your Excellency Uehara."

Hearing the voice coming from behind, Uehara turned his head and grew his mouth in surprise.

For some reason, Harumi turned into a transparent appearance, his skin and body seemed to have completely changed into a material, and his fragile brain and blood vessels could be seen through his skin and bones......

"The body has been transformed with precious chakra metal, and it is much stronger."

Qingming slightly followed Uehara to explain the strangeness of this body, and then said no more.

The scientific ninja was established by everyone, and Qingming and Uehara did not belong to each other, and Uehara was not good at asking anything more.

"This time, I came to get rid of Master Qingming to make forbearance."

With that, Uehara put a drawing in front of Harumi.

It was two long, narrow cube boxes, each filled with blades and hollows for catapulting fishing lines.

Qingming opened the rendering, a sturdy samurai, with a rectangular box hanging from his left and right waists, and the fishing line that bounced from the box firmly hung on the towering trees around him, and moved nimbly behind the giant, holding a knife to slash at the back of the giant's neck.

"This is a kind of ninja equipment that I conceived called the Space Stereo Mobility Machine," Uehara paused and explained to Harumi, "mainly for the ninja warrior corps, to make up for the lack of mobility of the samurai." ”

Although the scientific ninja has existing flying wings, allowing the ninja warrior legion to have a powerful movement ability that is not inferior to the ninja, the samurai's flexibility is still insufficient.

Not to mention anything else, ninjas can jump back and forth on tall trees, and can also attach chakra to the soles of their feet to complete a series of bells and whistles such as hanging upside down golden hooks, these seemingly simple actions cannot be completed by the samurai.

"The space three-dimensional mobile machine, just like the surface meaning, can move freely and flexibly when the space has a borrowing point."

"Here," Uehara pointed to a few hollows in the narrow box on the drawings, "the main thing is the device for launching the rope, of course, a simple rope will definitely not work." ”

Harumi heard it in a fog, and based on his extensive experience in ninja making, he was almost certain that Uehara must have seen this mature ninja tool, but he had only seen the combat mode and did not know how it worked.

"Where's the motivation?" Qingming pointed out the crux of the problem, "The samurai don't have chakra, how can they launch the rope?" ”

"Steam?" Uehara thought about it for a moment and said tentatively.

Steam?

Qingming was stunned, he originally thought about the complicated things, Uehara mentioned that it was a brilliant idea to use steam as power.

"Leave it to me." Qingming accepted the commission.

Uehara thanked Qingmei.

If you have watched the anime "Attack on Titan", you must not be unfamiliar with the space stereo mobile machine, human beings rely on this simple thing, I don't know how many powerful giants have cut off the back of the head.

Fishing line, steam, and blades, it's as simple as that, according to the flexibility of the space mobile machine in the anime, it can move flexibly in various complex environments, and it is not a problem to go through the forest and catch up with Yue, and it is not weaker than the ninjas at all.
