Once I returned to Konoha, I continued my life as it was. It was peaceful, and soon, I was twelve and about to graduate. In the past few years, I have trained quite a bit, but even further, I have developed my jutsu research, creating quite a few fantastical jutsus.
I have already learned everything Mito has to offer and have further developed my sealing skills. The most prominent one amongst them would definitely be the Yin-Yang Seal—a fuinjutsu I created which takes my excess chakra and stores it, much like Tsuna's Byakugou Seal, but its functions are much more than that.
First off, the seal filters out Yin chakra and Yang chakra, storing them separately. Then it proceeds to act as a compressor on the two chakra types, almost turning them into a liquid state. After which, Yin chakra would be supplied to my eyes, and Yang chakra to the rest of my body.
Yes, the improvement from this kind of technique is slow, but hey, it's continuously happening all the time, and slowly but surely, the enhancements stack up to be a big deal.
I even applied the Yang Seal (only the Yang part of Yin-Yang Seal) on Kushina, Tsunade, Minato, and even Grandma Mito, considering that the miraculous Yang chakra can even enhance lifespan. As for Kushina and Tsuna, they need to become stronger—Tsuna has way too little chakra.
I have kept most of my abilities as a secret for now, with only them knowing about it. Even Nawaki doesn't know much since he's an idiot and can't be trusted. Yeah, the man survived. He's 15 now. I saved him when he was about to die. Now, when I say I saved him, it actually means just that—saved. He still got blasted by that explosion tag, and I just let a clone heal him enough to ensure he could be carried back to the camp alive.
So, even if he is still alive, there are several burn marks on him, and he was left with severe trauma too. Anyways, with me awakening Wood Style, whatever expectations people had of him vanished, since they already knew that Nawaki wouldn't be able to live up to that—they just didn't want to accept it.
And from the first time Tsunade learned of my kekkei genkai... let's just say that we have gotten a lot closer. Yup, in the relationship department, I can say that Kushina and I are almost a couple, and Tsunade's case is complicated. She's older than me, but hey, I can manage to get her soon enough.
As for Kushina, well, we are essentially a couple. We act like one, but have never officially proposed. Anyways, those Kumo shinobi are lurking around, so the best moment to propose has come. Just beat a few Kumo shinobi and propose to Kushina. Well, with my level of strength, even if the Raikage were personally here, he couldn't kidnap Kushina.
Although my strength is no longer growing as fast as it used to, it's still significant. But hey, that was expected. Like, I am already at the top of Super Kage level, and adding jutsus only increases my arsenal, not my overall strength per se. But yeah, now I have enough jutsus that I can make wood clones with separate abilities and give them all Super Kage level strength.
Besides, I have already collected all Otsutsuki-related specimens. With my net worth being trillions of ryo and several companies worth hundreds of billions all over the world, I have the best research facility, best quality specimens, and the best brain in the shinobi world involved in research.
And yes, it is during times like these that you realize how busted clone techniques actually are. Like, they all share the same brain—my brain, a brain which is better than supercomputers. And when such clones sit together and do research? You get real shit done.
I have almost figured out the entire genetic sequence of the Otsutsuki, though that may very well just be Kaguya Otsutsuki's. Anyways, with a little more time, if I want to, I can even clone Kaguya. Imagine—during the Fourth Shinobi War, Kaguya breaks her seal and is suddenly attacked by hundreds of her own clones...
Though I am not very keen on cloning her, I plan to even further my research on Otsutsuki genes, add that to my body, and become immortal—and also a hell of a lot stronger.
In the meanwhile, a particular research of mine has come to fruition, which I am completing right now. This was a culmination of Fuinjutsu and Earth Style jutsu: a Gravity Seal. Very much like the ones in Dragon Ball, but I would be using it a bit differently.
The fuinjutsu was used to ensure automatic activation of the jutsu, and as I had mentioned before, Earth Style could tamper with gravity. Yes, this was it. It could make things lighter and make things heavier. Here, I just increased the gravity upon myself.
As you all may know, I possess Mahoraga's adaptability. So, what I plan on doing is placing gravity seals and imposing on myself higher gravity, and my body would soon adapt to it, making me stronger overall. Then, instead of training in it like they used to in Dragon Ball, I can just continuously increase the gravity, adapting to it all and becoming a hell of a lot stronger.
The fact that I possessed the Sage Body ensured that whatever injuries I received during this training would be healed automatically. But I still created two clones to give me a proper check-up between higher gravity training to ensure that there aren't any issues.
I once again teleported myself to a base—a specially made base, which was made of dense metal. It was very strong, made to manage super high gravity. Yes, I had a base built just for one particular training. Being the richest man in the world did have its perks. Even the daimyos didn't have as much capital as me.
I then proceeded to place several sealing tags across the room, created two wood clones on standby, and stood at the middle of the room. I took a deep breath, made a hand sign, and—
Activate! Gravity seals. 10x.
Boom.
I fell to the floor, unable to move. But this only lasted a few seconds. Then, I heard a click—the Wheel of Dharma had spun, and I had adapted yet another time.
I felt a massive force raging through my body. Then, a few more clicks happened, and now, I could move within the 10x gravity zone as if it was normal gravity.
'Damn, this turned out even better than I had expected,' I thought, examining my body. My durability had shot off the roof, and not to mention my strength, which had grown significantly.
My body had almost completely surpassed this world's level at just 10x gravity, almost reaching the level of people of the One Piece world next door...
So just imagine—what a 100x or a 1000x gravity would do?
