Chapter 4 - Physical Training [1] (1/2)

''Just to let you remember: Ninjutsu isn't allowed...'' My father said with a laugh before he said ''Start!''

While my Taijutsu is indeed weak, I still knew some martial arts from my previous but I decided not to use it, for now, running straight towards my father, I sent a simple punch just to see myself flying back to my previous position, lying in the ground, my father absolutely only held back his power enough for me to stay alive.

Suddenly, a refreshing feeling passed through my body as I the broken bones regenerated instantly and I felt stronger than before by at least 10%, do I have Zenkai? I guess this is one of the benefits of having a body literally made of Natural Energy, I'm immortal, this is amazing, I won't need to find a way to become one, haha!

''Did you see that, father? I regenerated instantly!'' I said, feeling a rare excitation that unfortunately died as soon as I saw a devilish smile on my father's face ''Yes... that's amazing!''

Aw, sh*t... here we go again, picking a kunai, I threw it to my father, that dodged and simply looked at me, smiling, I created a small space opening to make the kunai go into it and then another one behind my father, the kunai went back straight to my hand and my father, unprepared to the sudden appearance of the kunai on my hand, had his hand bȧrėly cut.

With an astonished expression, he asked me ''Little brat, how did you do that?''

Sooner or later, my space manipulation will be discovered but I plan to hide it for some time ''I'm not sure of it myself, it's like I can control the direction of it''

Well, it's not totally a lie and my father accepted but said ''I understand, however, you can't use this on Taijutsu training, I can feel that your speed increased some times, does it increase after you are seriously injured and then you regenerate?''

He led me towards a mountain and then, I prepared to fight against him to train myself but in the start, my father just taught me Taijutsu normally, pointing my flaws, I absorbed all of the knowledge like a sponge, this kept going for a month, when my father said ''I already taught you everything that I know about Taijutsu, now, we will start your physical training, let's start with the basic things, run around this mountain without using chakra to reinforce yourself for at least 10 times, you have to make your body catch up with your reserves of chakra!''

''Damn!'' I cursed loudly though I know it's wartime for at least some decades and getting stronger is essential, it's still terrifying to run around this mountain, well, what can I do, right? I started to run around this monstrous demon.

I knew that running even one time around it would be very hard... after around ten minutes, I completed a ŀȧp, something that wouldn't really be possible in my previous life, this mountain is simply... huge!
