— Reinforced clothing, and this, — lifting my shirt, I demonstrated the seal just above the abdomen. — One-time medical seal, can heal even very serious wounds, and if there's not enough chakra for everything, it will sustain the body's vital functions, so there will be a chance to get to the hospital.
— Hm, that's useful too, in our profession even such a chance is worth a lot,
— Ma shook her head.
— Then off to the shower, and be ready in twenty minutes, while I prepare new ink. And bring me your field uniform set, I'll apply the seals.
— Who's the boss here? — Sai muttered to herself, tiredly walking towards home.
— Of course, I am! — I replied to her remark and, casting a final glance at the ninja practicing with mini Rasengans, I followed.
Thankfully, everything I needed for the process was prepared, now it's just a matter of mixing Ma's blood with the ink and we can start.
— Boss, wake up! I did it! Wake up, I'm telling you!
— Huh?! What?!
Startled, I almost fell off the chair and began looking around, trying to figure out what had happened.
— I told you — I did it! — shaking me by the shoulders... me?
Blinking in surprise, I shook my head and looked again at my clone. Ah, the clone! Considering the situation and the scrolls laid out in front of me, I realized that I had fallen asleep while studying the scrolls that Sai had handed over to me from Uzumaki Mito.
— Did it work? — realizing what the clone was talking about, I jumped to my feet. — Show me!
We quickly headed to the training ground. Passing through the barrier check, I immediately noticed gradually closing craters in the ground all over the surface.
— Look, Boss, I did it! Now we have a controlled bomb!!!
Without waiting for my response, the clone formed a mini Rasengan in half a second, only slightly denser in appearance, and pointing his finger towards the untouched training dummies, "fired" it!
— Wow! — I couldn't help but be amazed, even knowing how it should look in theory.
The small glowing orb, attached to invisible chakra threads, rushed forward faster than any kunai I could throw, zigzagging and looping before crashing into the dummy from the side. But I noticed that the Rasengan didn't embed into the target like a normal one would; instead, it condensed into a point and then exploded!
Gasping, I stared at the aftermath of the developing technique — not only did one dummy disappear in the explosion, but the neighboring ones were also damaged by the rushing chakra streams and thrown several dozen meters away! The crater itself was about one and a half meters wide! This from a mini Rasengan, what would happen with a normal or larger one?!
— How did you do it?! — I turned to the clone.
— It's quite simple — in the morning, I remembered the first two steps of creating the Rasengan, and instead of trying to maintain the thread on the flows, I created a weak barrier around the rotating chakra streams, preventing excessive loss and sustaining rotation, and then attached the thread to it!
— Hm, I should have thought of that from the beginning! — I smacked myself on the forehead.
— Of course, now it doesn't embed, but due to compressing the shell for a fraction of a second and then releasing control, the chakra explodes and, in addition, slices everything around with the released streams, dealing additional damage! — the clone grinned bloodthirstily. — Of course, the difficulty of control and the amount of chakra invested in the technique doubles, if not more, but having a controlled bomb more than makes up for it!
— Hmm, this is no longer just a Rasengan, — I muttered, shaking my head.
In terms of speed, the new technique is very close to wind and lightning, the fastest elements, and at the same time, it's less costly and quicker to create, being a simple manipulation of chakra. And that's not even mentioning the possibility of control!
— How many can you make at once? — I asked the clone.
— So far, only one, — he sighed, — but I think with constant training, this number can be increased, just like with the mini Rasengans. By the way, I've named this technique the Bakuhatsu Rasengan!
Explosive? A fitting name.
— Alright, let's prepare to transfer all the accumulated information now, — I nodded contentedly and, sitting on the ground, assumed a meditative posture.
— As you say, Boss! — the Shadow Clone also sat down in front of me and closed his eyes.
