The battle continues in cycles, we would fight with one another until we where to destroyed to continue, then both of us would send pulses of chakra and repair our Megazords and subsequently continue battling.
Our fight was devasting and raging all around, I am painfully aware fo the environmental destruction we cause, but its kinda unavoidable as a battle of our level is bound to cause a lot of collateral damage, even when I and Madara have a surprisingly good amount of control, but even with it we basically create a huge circular battlefield where we are fighting, a huge crater composed of numerous small ones.
3 days passed with us fighting, we've been sending elemental jutsu like cheap candy, and sage Arts like they are a common occurrence, don't even mention our arbitrary use of mokuton creating and destroying forests and wooden constructs like they are nothing.
But what surprised me the most is Madara's stamina, the dude really became overpowered with his Rinnegan and Hashiramma cells, sadly for him, I am a Senju and I know exactly how to fight a Dojutsu specialized opponent, take out his eyes.
And that was exactly what I did, since I found the poor soul that was the temporary host of the Rinnegan previously, I start building a sealing matrix on the eyes, I would teleport to him when he was sleeping and would slowly build my seal on the eyes.
It took me a lot of time as the seal is simple yet complex, as I don't want to accidentally destroy such good eyes like the Rinnegan, I don't plan on using it, but I will definitely research them, so with my utmost care, I put a very complex seal on the eyes.
The seal function is simply a stasis to preserve the eyes and stop them from aging, even if the Rinnegan can't decay with time, precaution is still a good thing, the second function is a protection for the eyes in case some idiot treat them roughly, and the third function is a simply chakra storage seal.
While the last function of the seal may not spark the most usefulness for an observer, for me it is definitely the most important, the chakra storage seal would indefinitely suck chakra of whatever the host of the eyes is in such a slow and imperceptible way that even the best of medics would be hard-pressed detecting it, and even if it is slow, the amount of chakra it sucks of its user enormous.
So while my adversary is using his techniques and ey powers the most he can he is slowly but surely losing chakra at an alarming rate, which would be something very perceptible if we were on a low-level battle, but I am putting way to much pressure on Madara as he is basically doing his utmost to survive and try to win.
And when he is at his lowest I will activate the last function of the seal, The supercharge, its function is basically self explanatory, as it will simply make all the functions of the other seal enter a overclocked state.
