Konoha, my ninjutsu is infinitely upgraded!

"Put it in the ground?"

Asma Sarutobi nodded and said with a smile, "That's a good idea."

Uchiha Sasuke made a sphere with a diameter of 500 kilometers, and if cut in half, it would have a depth of [-] meters.

If all living and working areas are hidden underground, the regional space can indeed be fully utilized.

Soon, Sarutobi Asma followed Xiaonan and others to the underground entrance.

After a full depth of 50 meters, I came to the first underground floor.

Xiao Nandao: "The underground space is in an inverted cone shape. The space on the first floor is the widest, and the space on the last floor is the smallest."

"The first three floors, we plan to build an area that combines life and office at the headquarters of the alliance."

"In other words, some regular departments of the alliance will be on the upper three floors underground."

Asma Sarutobi glanced over, the first floor was already covered with buildings, but they were all made of wood, and it was obvious at a glance that Yamato built it with wooden tun.

Walking on the street, Xiaonan continued: "Starting from the fourth floor, it is used as the office area of ​​some special departments, as well as facilities such as the ninja training ground."

"At present, a total of eleven floors have been opened underground. The large-scale time-space teleportation technique is set in the middle layer, but each other floor is planned to set up a smaller teleportation platform to prevent the worst from happening, but it can also be timely. Transfer people."

Sarutobi Asma nodded, and then asked: "What about the attack and defense systems?"

"Every floor has reserved space!"

The answer was Yamato.

He said: "A large perception enchantment, which is used to prevent the enemy from sneaking in."

"A large defensive barrier can cover the entire air fortress, but it is not easy to build, especially if the area of ​​the air fortress increases."

"And, the larger the barrier, the more ninjas are needed to maintain it. Of course, according to the original plan, the fairy tree can also be used as a chakra provider."

"As for the attack and other defenses, there are designs from the ground floor to the last underground floor, especially the ground floor and the last floor."

Xiaonan took over the conversation and said, "The buildings on the ground floor, except for the water tower, are either used for ninja garrison or for designing offensive and defensive systems."

"The same is true for the last floor underground. In addition, the circle of each floor near the stone wall is the reserved space for the offensive and defensive system."

While walking, he introduced, and soon Asuma Sarutobi walked around the eleventh floor of the basement.

Overall, it's still an empty shelf.

But he already felt that it was very good, at least the space arrangement of each floor space had already been divided.

It's just that the buildings and the like are still quite crude.

The various offensive and defensive systems are only on paper.

After all, it was only three months before and after.

After returning to the ground, Xiaonan asked: "Master Asma, do you have any suggestions for the attack and defense system of the Sky Fortress?"

Sarutobi Asma asked back: "What do you think?"

"Of course it's the Tailed Beast Jade!"

Naruto spoke first.

He was not good at those before, so it was rare that he didn't speak.

"Or similar to the spiral pill, which concentrates and launches Chakra. It should be the easiest way to achieve both attack strength and distance!"

Apparently, Naruto hadn't thought much of this.

Uchiha Sasuke said: "I agree with Naruto's idea."

"Moreover, it may not be suitable if the attack methods are diversified. Sometimes the simpler the more effective."

"According to the current design, we can completely deploy a large number of Chakra cannons throughout the hemisphere. If we add the ground, then theoretically we can attack enemies in any direction, and we can form a phalanx attack."

"In this case, even if the Otsutsuki clan basically has the ability to absorb ninjutsu, it may not be able to cope with this intensive attack."

Sarutobi Asma nodded with a smile after hearing this: "Very good, very good consideration."

"However, as you said, Sasuke, the Otsutsuki clan masters absorption ninjutsu and chakra pupil technique, and even time-space ninjutsu that can collect objects like Otsuki Ichishiki."

"Tail beast cannons, or chakra cannons are really suitable for being arranged in a honeycomb-like dense state, but I think it would be better if some entities or ninja attacks can be mixed in."

After hearing this, Yamato said, "Asma, do you mean the kind of large crossbow?"

Large bows and crossbows are very common in the ninja world, and Hidden Sand Village will deploy such ninja tools to target enemies in the air.

Haruno Sakura said: "That kind of attack is not a threat to a powerful ninja, is it?"

"Especially the Otsutsuki clan."

Asma Sarutobi smiled and said, "Indeed, but it depends on how to use it."

As he spoke, he spread out his palm, and a sharp black stick emerged.

Immediately afterwards, under the eyes of everyone, lightning flashed over the black stick, and then the air exploded with a bang, and the black stick burst out.

"So fast!"

Haruno Sakura was startled.

Xiao Nan said: "Thunder Dun?"

Uchiha Sasuke said: "No, it's Xueji who eliminated Electromagnetic Dun!"

"Push the black stick through electromagnetic force, accelerate the black stick, and the attack power comes from the black stick itself."

"This kind of ninjutsu attacking the Otsutsuki family's ninjutsu absorbing pupils will not work. Of course, time and space ninjutsu, as well as Shenluo Tianzheng mastered by the eyes of reincarnation, can also be dealt with. The premise is that the pupil power is strong enough to capture the black stick. trajectory!"

"At least, my eyes can't catch its trajectory!"

After hearing this, Xiao Nan said: "In this case, it is very suitable."

Yamato watched Sarutobi Asma take back the black stick, and asked, "Asma, can such a method be achieved by designing a weapon device?"

"of course can!"

Asma Sarutobi smiled with incomparable certainty.

The principle of the electromagnetic gun, coupled with chakra as an energy source, will be easier to do than the previous earth.

Moreover, the attack intensity can also be adjusted by adjusting the injection of the amount of chakra.

Thinking about it, Sarutobi Asma asked Naruto: "Naruto, how is your Yin Yang Dun mastering?"

Naruto's body froze, and he squeezed out a smile and said, "That... it's not close, but it will be done soon!"

Sarutobi Asma nodded: "Master it as soon as possible, when the time comes, you can use Yin Yang Dun to make black sticks, which can be used as projectiles for electromagnetic guns."

"And you, Sasuke!"

"If your other eye wants to open the reincarnation eye, the change in the chakra properties of Yin Dun and Yang Dun cannot be avoided!"

Uchiha Sasuke nodded heavily: "Yes, Master Asma!"

Asma Sarutobi turned his head to look at Xiaonan, and said, "Elder Xiaonan, let's formally build according to the plans just now!"

"understand!"

Xiao Nan nodded solemnly: "I will arrange it."

Yamato quickly said: "Asma, at least we should plant the fairy tree first, so that we can really arrange the offensive and defensive system."

"no problem!"

Sarutobi Asma nodded.

He came here this time, in addition to inspecting, he also planned to plant trees.

Immediately, a group of people came to the central area of ​​the hemisphere.

The golden Samsara Sharingan emerged between Sarutobi Asma's eyebrows, but this time he wanted to activate it with this eye.

Fairy-Fairy-Tree Realm is born!

In an instant, in front of everyone, a fairy tree rose from the ground, grew rapidly, surpassed the high wall at the edge in a blink of an eye, and then stretched its branches and leaves, growing rapidly, covering the sky.

At the same time, the roots of the fairy tree grew like giant dragons in the ground, one of which went down, piercing through layers of space until the last layer.

The other thick root systems are like the tentacles of octopuses, passing through the soil layer, covering and hugging the eleventh underground space, or in other words, the entire hemisphere.

From the inner wall of the underground space to the outer wall of the sphere, the thickest part is 100 meters, and the thinnest part is 50 meters.

These tree roots run through the area.

And these are the taproots.

The main root soon grew more roots and drilled outwards, and then small fairy trees grew on the surface of the hemisphere.

Immediately, the originally bare hemisphere was covered by dense forests.

Asma Sarutobi closed the Samsara Sharingan, and said: "As long as there is a fairy curse seal, or the fairy mode cultivated through the fairy tree, or Chakra is recognized by the fairy tree, you can control the fairy tree."

Haruno Sakura immediately said: "Master Asma, if you have the ability like Bai Jue, can you even change Chakra?"

Uchiha Sasuke said: "Don't worry about this, the fairy tree must also have the ability to perceive good and evil."

"Sasuke is right."

Asma Sarutobi smiled and said, "Now Yamato, you can try to control the fairy tree and make this sky fortress move."

"Well... Naruto, you come to send chakra to Yamato!"

"no problem!"

Naruto immediately came behind Yamato and put his hands on Yamato's shoulders.

Yamato stretched out his right hand, and pressed his palm on the trunk of the fairy tree.

At this moment, he suddenly had a feeling.

This fairy tree is not a tree, but... a psychic beast.

It seems to have a consciousness of its own.

Very wonderful feeling.

It wasn't the first time he touched a fairy tree, but even the Konoha tree didn't have this feeling.

"Asma has gone one step further..."

Yamato secretly guessed, and then concentrated on injecting Chakra to manipulate the fairy tree.

In an instant, he felt that he was one with the fairy tree. The roots, every branch and leaf of the fairy tree were like his own arms and fingers, and he could manipulate them at will.

Soon he became familiar with how to control the fairy tree.

The next moment, the branches of the small fairy trees on the outer wall of the hemisphere shrank rapidly, leaving only a bare trunk.

Immediately afterwards, the end of the trunk was empty, like a cannon barrel.

boom!

The jet of air blasted the entire hemispherical fortress in the air, and then began to move.

However, Yamato did not maintain a good balance in the first control, and the sky fortress suddenly tilted, which caught Haruno Sakura and the others almost staggered.

"Sorry, I'm still a little unskilled!"

Yamato apologized awkwardly.

Xiao Nan couldn't help being curious, so he flew up, and when he looked outside, he was immediately startled.

The dense tree trunks spit out large and small air currents to push the sky fortress to move and maintain balance.

She turned around, and then thought to herself: "In this way, the sky fortress can not only move horizontally in any direction, but also rise rapidly."

Yamato adapted quickly, and it didn't take long for the sky fortress to move smoothly.

However, under the test, it is difficult for the sky fortress to move at high speed, and the consumption of chakra is also very large.

After stopping the test, Sarutobi Asma said: "For now, it's already possible."

"Let's complete a sample first!"

He already had some ideas for further improvements.

If you rely on Chakra, the consumption is really high, even if the fairy tree can store energy normally.

But, if nuclear fusion can be done...

Saying goodbye to Xiaonan and the others, Sarutobi Asma returned to Immortal Realm and couldn't help thinking about nuclear fusion.

The nuclear fusion he considered was not achieved through his own nuclear escape.

In other words, it cannot be achieved by relying on chakra as the "raw material" of nuclear fusion.

"Artificially extract raw materials, and then use electromagnetic escape to restrain them, so as to obtain huge electric energy, as the driving force of the sky fortress."

"Or, to use it as a weapon energy source."

Asma Sarutobi smiled: "Especially for the Otsutsuki clan."

"This is enough to make them absorb chakra, space-time ninjutsu, repulsion and other pupil techniques."

"Unless you master electromagnetic escape like me!"

Thinking of this, Asuma Sarutobi immediately created a shadow clone to try to do this.

A few days later, Ohnoki rushed to find him.

Time to plant a tree!

Sarutobi Asma and Onoki came to the mountainous area where the Land of Rain and the Land of Earth meet.

"Lord Asma, we have done it."

"In the past two months, there has been extensive rainfall in the Land of Earth, while the amount of rainfall in the Land of Rain has been greatly reduced, but at the same time, it has not caused the Land of Rain to experience drought."

"The originally arid area of ​​the Land of Earth has formed several lakes and rivers during this period of time."

Uchiha Yatsushiro and Uchiha Kota were very excited.

Asma Sarutobi had already obtained the exact data from Ohnoki, and nodded with a smile: "If that's the case, then we can end the mission here."

"Let's go to the Land of Earth!"

Sarutobi Asma immediately flew into the Land of Earth with everyone, and at this time Nagato also followed.

He also wanted to see Sarutobi Asma's ability to plant trees.

Soon, a group of people arrived at the fairy tree.

Onoki, Nagato and the others were still floating in the air, Sarutobi Asma landed on the canopy of the tree, the Samsara Sharingan on his forehead opened, and at the same time his perception quickly spread outward along with the roots of the fairy tree, and then spread all over The whole land of land.

Yes, the roots of this fairy tree have spread all over the ground of the Land of Earth.

Fairy-Fairy-Tree Realm is born!

With a thought in his mind, Sarutobi Asma activated this Blood Succession Snare.

In the air, Ohnoki kept staring at the ground below.

Suddenly, I saw tall trees rising from the ground.

However, these trees are not fairy trees, but a kind of forest tree that originally existed in the Land of Earth, and it only grows in places with abundant water sources.

As for Nagato and the others, their eyes were sharper, and they saw that there were still many weeds, various flowers, and shrubs growing rapidly and spreading out quickly.

Then, everyone looked into the distance one after another, and the originally bare area was quickly covered by green at this moment.

In some places a forest is formed.

In some places, there are patches of green grass.

In some places, there are large areas of bushes.

Nagato looked at it and instantly understood: "This is based on the amount of water resources to determine the type of vegetation and the degree of luxuriance."

"Amazing control!"

This is completely different from the wooden escape used during the battle, and the difficulty, he thinks, is much higher!
