Fujin's first thought was to use his summons to experiment. However, he quickly shook his head and decided, 'No, I'm still new at using this jutsu. Even though it is unlikely, if an accident happens and one of them dies, then that will be a great loss. I'll leave the village once again and find some rogue ninjas to experiment on.

That said, I need to practice this jutsu a bit before going out to experiment. I'm also very close to completing that seal. I'll go out once I'm done with that task. I also need to meet up with Shigeki and actually start working on the organization. Sigh, it's been a long time since I met Shigeki'

Thinking of Shigeki, a weird expression appeared on Fujin's face. Kasai Shigeki was the Jounin from Tanigakure whom Fujin had rescued while he was returning from the Land of Wind after completing his Anbu Promotion mission. Fujin made Shigeki the first member of his non-existent organization after making some promises and lying about the organization. However, it had been a long time since he had met him.

Fujin wondered, 'Would he still be even there? It's been over two and a half years, I won't be surprised if he left by now. Even though I promised to help him take the revenge, it won't be a surprise if he lost his patience after such a long time and left to get it himself.'

Fujin let out a sigh and thought, 'Oh well, nothing I can do. It was too early to start an organization in any case. If he has left, I will just have to start over. Besides, I didn't make much effort to recruit Shigeki or spend any resources or time. So I won't be losing anything.'

There was nothing Fujin could do about it. The situation just didn't allow him to do much about it. Even though he could have met Shigeki after he left the Anbu, there wasn't anything for Fujin to say to him.

Fujin stopped thinking about him and continued his training. The soldier pill he consumed would stay active for 5 days. And Fujin would require another couple of days of rest after that. Fujin decided that he would completely master the Flying Thunder God jutsu for low range within these 5 days.

Fujin made rapid improvements. His clones had already practiced the jutsu for sufficient time in order to ensure that he wouldn't face any danger. As a result, his main body was getting used to it rapidly as well. Every day, he became more accustomed to teleporting using the Void Dimension as a medium.

Three days later, Fujin's bell rang, marking the first time he was disturbed in recent days. Fujin was planning to ignore it and focus on his training, however, the bell kept ringing continuously.

An annoyed expression appeared on Fujin's face. He cursed, "Which bastard is it?"

He activated his chakra field and sighed while muttering, "I should have known."

A Shadow Clone popped next to him and left the basement. He opened the door and saw an over-enthusiastic blonde boy. Naruto excitedly said, "Fujin, I managed to stick the leaf to my forehead for 2 hours straight!"

Naruto was extremely excited. Though Fujin taught him a few Wind jutsus which he had to work hard to learn, it was this exercise that was the most difficult for him to complete.

Fujin's clone thought, 'He finally managed to do it. His speed fell considerably in this exercise. I expected him to reach this stage a month and a half ago. By comparison, he has progressed rapidly in Wind jutsus. I suppose he just got bored and lost his drive. Well, not surprising considering how boring it is.'

Naruto said, "You promised me that you'll teach me something cool after I manage to do it."

Fujin's clone nodded and said, "Sure, but show it to me first."

Naruto's expression became awkward. He asked, "Can't we directly begin learning it?"

Fujin's clone shook his head and said, "It is important to have your basics right. Otherwise, major issues can happen when you try to learn what I am about to teach you. In the worst-case scenario, you will be injured and might not be able to leave the hospital for weeks."

Fujin's clone's expression was extremely strict and serious. It was so serious that Naruto gulped in nervousness. He said, "Alright, I'll do it."

The clone thought, 'Who told you to keep ringing the bell and disturb me? Now sit in one place for another couple of hours.'

What the clone said was obviously bullshit. Though Naruto could get injured due to falling, it wouldn't be serious enough to even visit the hospital, let alone be admitted for several weeks.

Naruto and Fujin's clone walked over to the training ground. Naruto grabbed a leaf and obediently sat down to meditate. He placed the leaf on his forehead and closed his eyes. Fujin's clone set a timer on a stopwatch and sat in front of him.

1 hour and 53 minutes later, Naruto couldn't maintain control anymore. Naruto opened his eyes and looked at the stopwatch. His eyes widened as he realized that he was 7 minutes short! He looked at Fujin's clone, only to see Fujin looking back at him with a deadpan expression.

Naruto became nervous and said, "I really held it for 2 hours earlier. I don't know how I fell short right now."

Fujin's clone sighed and said, "It's fine. I guess it was a one-time thing. You'll still need some time to be able to do it every time."

Naruto became dejected on hearing that. He would still have to wait for some time. Fujin's clone watched the range of emotions and panic on Naruto's face until he was satisfied. With a smile, he said, "But, this is good enough. I'll train you now."

Immediately, Naruto became very happy and cheered loudly. The clone sighed internally and thought, 'Dealing with Hiruzen and Shikaku frequently has made me weird. Since when did I begin taking pleasure out of making others feel an emotional turmoil?'

Fujin did take pleasure in making experienced folks like Hiruzen and Shikaku feel such turmoil. But that was different. Both were extremely experienced and shrewd. Fujin initially enjoyed it because of the challenge of achieving that and due to how stuck up those two were. However, it was different with Naruto. Naruto was the complete opposite of those two. He was naive, inexperienced and listened to Fujin obediently. So Fujin didn't expect that he'd get the same pleasure from making him experience that.

Fujin's clone muttered to himself, 'Those two geezers twisted my personality. Either that or perhaps because I know that Naruto will become very strong in the future as well. Sigh, whatever.'

Naruto broke Fujin's train of thought by asking, "What will we be learning?"

Fujin's clone said, "I'll teach you how to climb trees."

Now, it was Naruto's turn to watch Fujin's clone with a deadpan expression. A smirk appeared on the clone's face. Naruto complained, "I already know how to do that, believe it! Teach me something cool!"

Fujin's clone chuckled and asked, "Are you sure you can do it?"

The clone got up and walked to a tree. To Naruto's shock, he began walking up the tree with just his feet while his hands were in his pockets. He soon stood upside down on a branch and asked, "Is this cool enough?"

Naruto immediately nodded repeatedly and said, "Super cool! How did you do it?"

Fujin's clone answered, "To do this, you have to release chakra from the bottom of your feet. Use that chakra to stick to the tree. Then you can climb on trees like I did. Try it."

Naruto immediately released chakra from his feet and tried climbing on the tree. Needless to say, his feet slipped and he fell to the ground.

Fujin's clone chuckled and said, "It's not that easy. The chakra you release from your feet has to be an exact amount. If it is too little, your feet will slip and you'll fall down. If it is too much, you'll damage the trunk and won't be able to continue walking up.

So, it requires very good chakra control. That is why I had to do the leaf concentration exercise until you could reach 2 hours."

Naruto nodded and said, "Alright, I'll try it."

Fujin's clone stopped sticking to the branch and dropped to the ground. He made a hand seal and slammed his hands to the ground. Immediately, some changes happened on the surface, but nothing much happened. Naruto looked at Fujin's clone with confusion.

Fujin's clone said, "I have softened the ground. So, even if you fall, you won't be hurt much. Keep training under this tree for the next half an hour. I'll teach you something else as well today."

Naruto immediately became excited and continued trying to climb up the tree.
