Fujin quickly analyzed his Shadow Clone's memories. He let out a sigh at the questions that his clone had wondered about. Unfortunately, he wasn't strong enough yet to resolve those mysteries. Though they weren't as miraculous as his transmigration, they were still concepts beyond his current strength. However, unlike his transmigration, Fujin was hopeful that he would figure out these mysteries in the future.
He quickly removed those thoughts from his head and focused on the Flying Thunder God jutsu. He let out a sigh and muttered, "I had a feeling that I would experience a breakthrough only two weeks after I began practicing the third step.
To think that I would need another month of training to actually achieve that breakthrough! And, that is when I kept training with 15 Shadow Clones. That is equivalent to training for 16 months. No wonder such a technique didn't exist before Shadow Clone jutsu was created. Who'd spend so much time on this while your clan was constantly at war?"The inaugural upload of this chapter took place via N0v3l-B1n.
Having analyzed the information, Fujin dispelled his Shadow Clones. All their experience and analysis poured into Fujin's brain. He spent a few minutes getting his thoughts together.
He analyzed, 'The first two steps to learn the Flying Thunder God were straightforward. However, the third step is quite complicated. In fact, it is further divided into four more steps.
The first step is to sense the Dimensional Void and send my chakra into it. Sensing my markings from the Dimensional Void is also a part of this step. It took me a month and a half to complete this step.
The second step is to transport a jutsu through the Dimensional Void. Unfortunately, only the jutsus where chakra is concentrated can be transported through the Dimensional Void. Jutsus like Infinite Breakthrough jutsu will directly collapse in the Dimensional Void.
The reason for this should be the intense pressure my clone felt. I will have to add a layer of chakra coating to my jutsus for them to maintain their forms while transporting through the void. Now that I think about it, Rasengan and its elemental forms will be perfect for travelling through the Dimensional Void. They are made purely of chakra and hence don't need any such layer of protection.
Fujin looked around in his basement. He analyzed, 'Though I do have a lot of seals here, I doubt they can endure a barrage of Rasengan. I will need to increase the protection.'
Fujin made the confrontation hand seal. Immediately, several seals on the walls and pillars began glowing. One shadow clone appeared next to Fujin. He moved to the center of the basement and sat there. Immediately, several seals appeared on the floor and the ceiling with the Shadow Clone at the center. Immediately, a barrier appeared and covered the walls, pillars, floor and ceiling in the basement. With the barrier, Fujin no longer had any worries.
Fujin created a new set of Shadow Clones to assist him in training. All of them began trying to teleport a Rasengan to the markings in front of them.
All their attempts were unsuccessful as Fujin wasn't used to Dimensional Void yet. Only a small amount of chakra reached the markings, causing a series of small explosions in the basement. Fortunately, the barrier ensured that his house was undamaged. Unfortunately, Fujin overlooked one important factor.
Fujin dispelled his clones as his breathing became heavy. He cursed, 'Shit! I forgot that my chakra reserves won't be able to sustain a continuous barrage of Rasengan! Not to mention, keeping the barrier up while enduring a barrage of small explosions burned the clone's chakra rapidly as well. I'm already empty.'
There was no helping it. Even Naruto wouldn't be able to sustain a Rasengan Barrage for more than a few minutes unless Kurama provides him with his chakra continuously. For Fujin, sustaining it for even a few minutes with 15 Shadow Clones was too difficult. Even more so when the Rasengan had to be sent to the Dimensional Void since that required chakra as well.
Fujin sighed and decided, 'I guess I have to stick to the Wind Explosion Sphere. It'll be a lot harder to do than the Rasengan. But it won't be very chakra exhaustive and I won't need to use a barrier as the normal strengthening seals should be sufficient to shrug off the damage due to some winds.'
Fujin took a break and continued his training once his chakra had recovered. Even though Wind Explosion Sphere consumed just a fraction of the chakra as compared to Rasengan, it still burned Fujin's chakra very quickly. As such, his speed of training the Flying Thunder God jutsu slowed.
However, his progress with the Gate of Healing was steady. Three days later, he managed to open the Gate of Healing for the first time!
