Fujin thought, 'Though this is good, I'll have to keep up this training plan for a long time to ensure that this is permanent and to keep increasing the amount of chakra I infuse in my body. If I don't, the amount of chakra I can infuse into my body will slowly decrease. Over a few years, my body will lose this ability. Anyway, time to test it!'
Fujin clenched his fist and punched the ground as hard as he could. A loud sound was heard throughout the training ground. Cracks spread on the ground like a spiderweb for a dozen meters from the spot where the fist landed.
Fujin analyzed, 'Not bad. It's definitely much stronger than my normal punch. No ninja with a normal body would want to be on the receiving end of this. Even with Iron Skin jutsu, they will feel the pain and might suffer some internal damage. Now…'
Fujin concentrated his chakra on his fist. He was using the Senju Taijutsu Style alongside Guy's Strong Fist Style. Once again, he punched the ground with all his might at the same spot.
This time, the impact of the blow could be felt throughout the training ground! The birds, that were brave enough to still live in the trees in that training ground, immediately began flying away due to the tremors! A few people, who were walking close to the training ground, turned their heads due to the sound that was heard!
Fujin, who was the source of this commotion, was standing in a hole in the ground that had collapsed due to his punch. For several dozen meters, the ground was a wreck! The cracks had opened wide and several rocks were thrown out of the ground. Fujin himself was covered in dust. However, a wide grin could be seen on his face.
Fujin wiped the dirt on his face off and analyzed, 'Great. In terms of destructive power, this isn't too far away from Tsunade's level. However, in terms of usability, it is still far behind. The time I take to concentrate my chakra on my fist reduces its effectiveness in a high-speed battle. My opponents will easily sense it and take evasive actions.
That said, with my wind jutsus, it isn't critical for me to improve this aspect. I'll be able to shred my opponents far faster instead of trying to obliterate them with a punch or kick. I can also use my Wind Domain to slow down my enemy and attack them with this if Wind attacks don't work for some reason. Regardless, this is very good.'
Fujin returned home to have a shower. Due to the intense training and being covered in dust, his body was quite dirty. After a small break, he immediately went to find Guy.
As usual, Guy was training his three students. They had just finished an intense training session when Fujin showed up. Immediately, Neji and Tenten's expression became dark. Tenten cursed, 'Great! We have just rested for 10 minutes and this monster has already shown up! Why did he arrive so early today?'
Guy smiled on seeing Fujin and instructed, "I and Fujin will spar for now. Until we are done, you three have to run 80 rounds around the training field on your arms."
Tenten wanted to cry, unfortunately, her tears had dried out long ago! Since Fujin regularly showed up to spar with Guy, Guy decided to have his students train while he sparred with Fujin. After all, there wasn't much for them to learn from their fight because the three Genins couldn't even follow their movements.
As such, Guy gave them very difficult training tasks to do while he and Fujin sparred. The tasks were so difficult that none of them had even completed them once. To make matters worse, Guy continuously kept increasing the difficulty of the training tasks little by little on a daily basis to push them more. And, if either of the three Genins dared to slack off, Guy would lead them to train in a way that made them embarrassed like following Guy on the streets of Konoha while all 4 of them walked on their arms.
Unwillingly, they left to train. Guy looked at Fujin and said, "You are early today."
Fujin smiled and said, "It's a special occasion. Let's fight. No warm-up today."
Guy was surprised. He began unleashing his chakra and fusing it with his body while exclaiming, "Alright! Let the power of youth explo…"
Guy's words got stuck in his mouth as he noticed Fujin doing the same. A grin appeared on his face as he said, "No wonder you are so impatient. I can feel the excitement of an intense spar!"
Guy disappeared from his spot and attacked Fujin, who disappeared as well. As usual, the two engaged in an extremely high-speed fight. The only difference was they were even faster this time! The ground, which already had scars from their previous spars, was changed beyond recognition.
Two hours later, both were breathing heavily. Especially Fujin who looked completely out of breath. He muttered, "Damn, using this continuously is very exhausting!"
Guy replied, "You have just learnt it. Managing to keep it up for two hours is very impressive. More than chakra reserves, this method puts a strain on the body. That is why you are so exhausted. In time, not only will your stamina improve, but you'll also learn to better manage it by easing on the chakra depending on the battle situation."
Fujin nodded. He could sense that his chakra reserves hadn't decreased much. But his body was just too tired. He looked at Guy and analyzed, 'Even though I managed to infuse chakra into my body, the amount of chakra I can infuse is far less than him. In addition, his Taijutsu is far more refined than mine.
It looks like forcing him into using Eight Inner Gates would be impossible unless I use Wind jutsus in the spar. Even then, he might just accept defeat and not use the Inner Gates. After all, this is merely a spar.'
Seeing Fujin silent, Guy said, "Just increase the intensity of your training. If you can't, then increase the time you train maintaining your current intensity. You will be able to maintain this state for far longer."
Fujin nodded. He looked at Guy and said, "I will. But I have a favor to ask."
Guy asked, "What is it?"
Fujin directly asked, "I want to learn the Eight Inner Gates technique. Can you teach me that?"
Guy was surprised by Fujin's directness. He thought, 'Even Kakashi wasn't this direct.'
He became quiet and began thinking. Fujin didn't disturb him. He thought, 'This request is no doubt huge. For one, this jutsu is a forbidden jutsu. Secondly, it is his trump card. If someone came to me and asked me to teach them my wind domain, there is no way I would agree. I would either directly say no or make some excuses depending on who asks.
That said, Guy isn't the only one who knows about the Eight Inner Gates. So there will be other means of getting my hands on this technique. It's just that I'll not have the benefit of someone who has learnt this technique guiding me, making it slightly more difficult to learn this jutsu.'
Fujin observed Guy and waited for his decision. After a couple of minutes, Guy said, "I can teach you. However, the Eight Inner Gates is a very dangerous technique. It has a lot of risks."
Fujin nodded and said, "I know. Opening the Eighth Gate would result in death. Even the earlier gates put a lot of stress on the body. If it is used recklessly, it could cause irreversible injuries or even cripple the user."
Guy was surprised. He said, "It looks like you did the research before asking me."
Fujin nodded and said, "It is a forbidden technique. I won't mess around with it."
Guy smiled and said, "Alright. I'll teach you this technique. But before you begin, I want to know how much you want to progress in it. Do you want to focus entirely on it? Or do you just want it as a hidden card and use it to gain an advantage?"
Fujin sighed in relief internally and thought, 'Good. If he hadn't agreed, I would have had to pester Hiruzen again. Not to mention, learning a forbidden jutsu alone has a lot of risks.'
Fujin answered, "I can't focus entirely on it. My main combat method still revolves around Wind jutsus. I want to learn this so that I can use it in instances where my opponent is somehow immune to my Wind jutsus and other skills, forcing me to rely just on Taijutsu."
Guy frowned and said, "I can't think of any such opponent. Still, it's a shame that you don't want to focus on this entirely. With your willingness to work hard, you would have progressed a long way through it."
Fujin smiled and said, "I might still go a long way, Guy. I'll decide how much to focus on it after learning how to open a few gates. Can we start now?"
