Naruto was still working on the bowl but couldn't make any visible headway. I didn't want to kill Jigen immediately because I wanted to see how far along Naruto has gotten. I flicked a small weak energy ball at the giant bowl and the impact made it crack.
Jigen: What?!
Sage: There's no need for you to die so quickly, continue fighting with Naruto. If you still believe that you can fight me than you better kill me before Naruto breaks out of that bowl.
I flicked at Jigen before he even moved from his spot to attack me, hitting him in the left shoulder. Jigen was taken aback not realizing what happened. By the time he saw that all I did was flick air at him, Naruto broke free.
Naruto: Damn, I was too distracted. Huh, you didn't kill him yet have you, Sage-nii?
Sage: Nah. You're good.
Naruto and Jigen reengaged in combat. This time, Naruto was paying attention to Jigens every move. Naruto used his Rinnegan as he flashed behind Jigen. Jigen reacted but Naruto read his muscle movement and stopped him before hand. Naruto jumped back as Jigens muscles began to shrink and knew that he was going to minimize. Since they both didn't really use big Ninjutsu, they fought in Taijutsu mainly. Naruto grew up with me so he was beyond Guy and Rock Lee in Taijutsu. Like Rock Lee, Naruto trained with weights on in order to keep up with me, but since he had such a high tolerance for pain and trained a lot the results were obvious, Jigen started to lag behind.
Jigen started to take solid hits and the black thing on his abdomen looked as if it were breaking apart. Jigen then started to transform into his original Otsutsuki form and only for a while started to gain an advantage over Naruto. Naruto stepped back and took off his weights on his wrists.
Jigen: Is that some other seal. It won't help you.
Naruto chuckled, shook his head and threw the weights at Jigen. Jigen let the weights pass him by and as the weights hit the floor, a great impact hit the ground. Even Jigen had to look over the impact of the weights. I nodded my head and thought, "good for him, he kept up with his weight training".
Sage: Yo Naruto, if you want the weights heavier I can help you with that.
Naruto: Thanks, I was outgrowing those anyway.
Naruto closed the distance in a blink and caught Jigen in the jaw with an overhead left. Jigen crashed into a boulder. Jigen exploded out of the boulder and flew into Naruto but Naruto caught the entire motion.
Jigen: I don't know how you have obtained the Rinnegan but I will gouge them out along with your life!
Sage: Honestly, have you even done any research on Naruto or me? Weren't you around for nearly a thousand years and all that grew was your ego?
Jigen looked at me in anger and continued to try to throw the shrunken black rods at me. The rods were bounced off me before they even reached me due to my natural excess in energy. Naruto was in a similar situation and was naturally fending off the rods. Other than the shrinking, which Naruto and I kept up with and could see thanks to Acacia's full course and Sharingan, Jigen had little to offer to oppose us.
Jigen stopped mid-air and spoke.
Jigen: Everything I needed to know was gathered in the few years after you killed Momoshiki, Urashiki and Kinshiki. You should not be this strong.
Naruto: Even my son is not that much of a fool to not keep tabs on his main opponents.
Sage: I guess you can blame your ego for your plans failing. No to mention, didn't you find it odd that there was an influx of people who had the Rinnegan and Tenseigan in the leaf village that were not Uchiha?
It seems that it finally dawned on Jigen as his eyes widened.
Jigen: You killed certain Uchiha members again and harvested their eyes. The people that now have them are those that could make them evolve.
Naruto and I looked at each other and in unison said out loud.
Naruto&Sage: ARE YOU SERIOUS?!?!
Sage: Let me ask another question to narrow down your guess. Have you ever returned to your home planet to see if you could regenerate your body back? Have you ever returned to report on Kaguya or your situation?
Jigen looked bewildered.
Sage: Either you couldn't return or wouldn't return. Your trip may have been one way or you were too embarrassed to report your failings. Most likely, you planned to use the Earth for the God Tree and once you've eaten the fruit you could make the trip back to where you came from and give out the fruits so you can become Gods, right?
Jigen: How?...You…
Sage: You still haven't figured it out? Even if your plan succeeds, there is no home for you to return to.
I said with an evil smile on my face.
Sage: So, it's no longer a smiling matter when the destroyers get destroyed huh?
Naruto: Hypocrite.
Naruto took off the anklets, coated himself in intense heat emitting Chakra and looked at me briefly before completely destroying Jigen. Naruto's speed, reflexes, senses and of course power rose to a very high degree. This was the first time I have ever seen Naruto like this, so I used my Ginga Rinne Sharingan to see what it was. The form looked like a unique fusion of Chakra. Chakra from Naruto, Kurama and natural Chakra from the world. Upon closer inspection, the overcoat of Chakra looked almost like the Sun, which explains the high heat. So, it's not just mixing Chakra together but taking pure energy to achieve nuclear fusion. Very dangerous but very powerful. It does give Naruto an insane stat boost but at a great cost. If I were to compare it to something, I can only think of Goku's Kaioken. Fortunately, Naruto had undergone extreme training even without me in order to achieve that mode.
Naruto: No more dragging this out. Die.
Naruto disappeared and reappeared behind Jigen. Naruto pierced through Jigen in one thrust of his left arm and cutting off his head with the right horizontal chop. Naruto grabbed Jigen's head and incinerated it to dust. Once confirming that Jigen or Isshiki is dead by sifting through the dust, Naruto returned to normal and plopped on the ground. I may have lost a pair of eyes but it didn't matter. I took out some food from my pocket dimension and gave it to Naruto. I chose a meal that will restore Naruto, not just physically, because the new form he took on burned more than just physical energy and Chakra.
Sage: That new form of yours, it also burns through your lifespan doesn't it?
Naruto: You noticed it, huh? Through the advancements of technology and its new discoveries, I was able to come up with this form. I call it the Baryon Mode. Through Sage mode I was able to find balance between Senju energy, Chakra and Kurama's Chakra. Through science, I was able to use the energies to their extreme.
Sage: Eat what I gave you. You should be able to get back what was drained.
Naruto took one bite and all the life energy that he used up had returned. For good measure, I used a crushed Senzu bean as a seasoning so that all his energies could return.
Naruto: I don't know what I would do without you Sage-nii. The first time I used this form I was out for a week. I trained and was able to withstand the drawback like I am now but I wouldn't be able to move.
Sage: I'm guessing that every time that you used it you also felt weaker every time and that's when you found out that it drained more than just your Chakra and physical energy, right?
Naruto: Right. I was trying to power up to see if I could rip open a Yomotsu Hirasaka and try to find you, but…
Sage: Family and the village.
Naruto: Right.
Sage: Hopefully that was the last Otsutsuki and we won't have any more mishaps. Trust me, this will not happen again. I already taught Mei, Tsunade, Rose and Ryu how to use the Yomotsu Hirasaka. Now that you took the eyes as well, I can teach you.
