Fujin was sitting on the training ground while waiting for his chakra to recover. His clones had continued working on the remaining seals. Fujin didn't bother visiting the training rooms because he was deep in thought. His mind was occupied with thinking about what he wanted to create.

Once his chakra recovered, Fujin got up. He began emitting chakra into the air from every chakra point on his body. As soon as the chakra was released, it transformed into the wind and mixed with the surroundings. If a normal person saw, he wouldn't feel anything different.

However, any ninja would immediately feel the high amount of chakra concentrated in the area. Fujin analyzed, 'Unlike the Wind Style Genjutsu, this can be easily detected. But doing what I have in my mind can't be done with that little amount of chakra.

But, it shouldn't be an issue. Even though I'm sacrificing stealth, it will be compensated by the abilities of this technique.'

Fujin focused his eyes on a branch of a tree in front of him. More accurately, he focused on the wind around the branch which had his chakra mixed in. In an instant, the wind attacked the branch. The winds caused the branch to sway. A few leaves fell but no damage was inflicted to the branch.

Fujin furrowed his eyebrows as he analyzed, 'This will take a lot of time.'

He closed his eyes and continued emitting more chakra in the surrounding area. As he did, he also focused all his attention on sensing his wind chakra that was mixed into the surroundings.

After 5 minutes, he snapped his eyes open and exerted control on the chakra he had released. Immediately, winds began flowing around him. The branches of the trees around him began swaying in the wind and a few leaves broke off.

Fujin sighed and thought, 'It's very difficult to exert control over this chakra. Making it sharper is even more difficult.

Though my control over wind jutsu is normally very good, it is because I manipulate it however I want before it leaves my body. Even though I have some more control over jutsus like Blades of Wind and Infinite Breakthrough due to Yin-Yang manipulation, it still has more to do with what I do before I launch the jutsu. As I speculated, this will be a rather difficult technique to create.'

Memories regarding his idea flashed into his mind. Fujin thought, 'It has been a long time since I wanted to create something like this. I first had the idea after seeing the rank E Wind jutsus.

But the idea was very vague back then. And I didn't have any idea of how to even start working towards it. That changed when I fought with Susumu. His application of Wind Release to cast Genjutsu gave me an idea of how I could start.

My idea is to emit chakra into my surrounding winds and control it. If it goes as I want it to, then I should be able to create extremely high-speed winds at will. I should also be able to make those winds extremely sharp. At a later stage, I should also be able to mix Vacuum blades in this technique.

Once it is completed, it will be akin to the Wind variant of the Raikage's Cloak of Lightning. Though it won't buff my speed or physical defense and attack like the Cloak of Lightning, the entire area around me will be a death zone.

I can use the Winds to tear apart anyone who enters in the range of this technique. I can also use the winds to defend against ranged attacks. And though I'm not sure whether I can use this to buff my speed, this could potentially aid me in another way. That is, the power of flight.'

A glint appeared in Fujin's eyes. The ability to fly and to create such a domain around him were among the top abilities that he craved. He thought, 'Considering the nature of this technique, it can't be called a jutsu. Instead, I will call this my Wind Domain! Once I master it, even Obito would be very wary of sneak attacking me in the middle of a battle. He can enter my domain, but he can't deactivate his intangibility while he is in it.

Unfortunately, this technique will be very difficult to create. According to my calculations, I'll need at least a year of extreme training to make this technique workable. Raising it to a level comparable to Raikage's Cloak of Lightning will need even more time.

In addition, I will have to break this technique into several parts as trying to directly master it in its entirety will be doing too much at the same time. Also, these parts would help me keep track of my progress. As for what these parts will be'

Fujin chuckled as he thought, 'They would be the rank E jutsus in the library. Wind Levitation jutsu, Projectile Control jutsu, Wind Retrieving jutsu and the rank D Propelling Winds jutsu will be ideal for creating this technique. It's just that instead of using my own chakra, I need to perform these jutsus with the chakra I have emitted into the surroundings.

Of course, these alone won't be enough. They can improve my control but won't help me much in attack. For that, I need to create Blades of Wind and later Vacuum Blades with the emitted chakra. In addition, I need to create a new jutsu.

The jutsu will be the ninjutsu variant of Wind Style Genjutsu. While maintaining the stealth aspect, I want to form an attack with the wind chakra I have emitted. Since the chakra will be very low, I can only create one attack. One simple cut with sharpened winds at the neck. I will call it the Silent Cut jutsu.

This will have two usages. The first one is obviously for assassination. The second is to use this to sneak attack anyone who detects my technique, stays a safe distance away and is able to defend against me.

Hmm Though I have a few more ideas, this should be enough for now. I'll begin my training.'

Fujin created 5 shadow clones. Fujin and his clones spread out around the training ground. Each of them emitted their chakra into the air and tried using it to use the Wind Retrieving jutsu.

Fujin quickly became engrossed in his training. Though the jutsu had the potential to require a large amount of chakra, Fujin didn't have much mastery over it. So he and his clones only released as much chakra as they could control.

Due to this, Fujin's chakra regenerated at a much faster rate than he and his clones could use. So apart from needing a break after dispelling and recreating the clones working on Fuinjutsu, Fujin didn't need any other break. Fujin ignored everything else and continued his training.

Three days later, a ninja wearing a mask appeared in an underground tunnel. He walked towards a room and entered it. He knelt and respectfully said, "Danzo-sama."

Danzo looked at him and said, "Torune, report your observations."

Torune reported, "I tried keeping an eye on Suzuki Fujin for the last 10 days. For the first 6 days, he woke up at 4:30 AM. He went to training ground 23 at 5 AM. He stayed there until 10 AM. From 10 AM to 1 PM, he went to the training ground where Might Guy was at.

He spent 3 hours there before going to have lunch in either Yakiniku, Ichiraku or his house. He returned to the training ground 23 after lunch and spent another 4 to 6 hours there before going back to his house.

On the 7th day, Guy had to go on a mission. So Fujin stayed in the training ground 23 until Lunch time. But, in the last 3 days, he has stayed all the time in the training ground 23. He hasn't left for food or sleep. I believe he is using a soldier pill to train continuously."

Danzo was surprised. He thought, 'So much training? Is he preparing for something? Or is this how he always is?'

He asked, "What is he training in? And did you inspect his house?"

Torune answered, "I planted some of my insects to spy on what he and Guy were doing. They both sparred for 3 hours straight on a daily basis. Fujin's Taijutsu is very good. He uses the Senju Taijutsu style. In a pure Taijutsu fight, I don't think any Root ninja will be a match for him.

As for what he did in training ground 23"

He took a pause before continuing, "I couldn't find out. He keeps his chakra field activated in the training ground all the time. I tried sending in some insects, but he detected them and even tried looking for me.

I planted some bugs in the training ground in the night, but he could somehow find and kill all of them before he began doing whatever he was doing. So I have no idea what he does there.

As for his home"

Sweat gathered behind Torune's mask before he could give an answer.
