"Hm." Realizing that Tatsurama was correct, Sadazane was silent for a few minutes as he thought about that statement. It was right. If Noragakure hadn't seen what the Jihibiki were doing, they might still be at war even now. It was something he failed to realize. "War in the caves is much different than here. We do not fight amongst each other much. If we do, we are punished. We cannot afford to let us be split apart." At the mention of Saga Masato, he would give a curt reply. "If he truly can destroy anything or anyone, then why hasn't he done so? I believe he may have to do something more for his goals if he wishes to enact them."

Watching the blade that formed soar up towards the sky, he would take note of it before looking back towards Tatsurama. "Can it cut the Gunshot? I understand that elements interact differently. Water and Wind seem as if they do not mix." Sucking in a breath and weaving a few hand seals, another pool of water would form in his mouth before it was released as a high pressure bullet, soaring up to the sky before reaching the pinnacle of its arc and falling back down towards the Suimen Pond with a crash, disturbing the still water again.

"It'll split Gunshot, it's two full ranks higher. Not to mention I can enhance it if I so choose. That is something valid, fighting against each other leads to being punished. Above the ground we are too far spread to properly enforce this, but the threats to us are so numerous I don't believe we can afford to be as splintered as we are. If we had a tighter grasp this war wouldn't even have been possible."

As he said this he cast his hand to his side once more to gather the chakra within his hand, attempting to concentrate it as greatly as he could within his chakra system before slashing his hand in the direction of the pond. As before he released a crescent of wind chakra, though this time it was a step bigger due to him channeling a greater amount of chakra into it with his near mastery of ninjutsu. Unleashing for the second time Beast Tearing Palm. He thought to himself of the possibility of developing its more skilled variation, but what was the use with his jutsu speed?

"How sad that S-Rank techniques may never be practical for me."
Derek
"I agree with you on that. The lack of unity with people above ground is very unlike the caves. Even if we disagree, we must work together or we all die. With freedom comes more problems." A pause. "However, that freedom has made you Surface Dwellers what you are. There is nothing that does not have drawbacks is what my master used to say when training. Every action has its risks, every decision a miscalculation. There is nothing that is perfect." 

Listening to the mention of the technique, he would jot that down in his mind's eye for the future. It sounded like a good technique to learn. As the crescent wave shot into the air again, Sadazane would turn to look at Tatsu. "If it is not practical, then work on what is. If it can kill the enemy, it has use. If you do not need it, do not wish for it. A saying of the elder members of my people. They were what you call utilitarian."
Hattie
"While an S-Rank has unimaginable power, the time it takes for the average ninja to deploy one is a great risk. Though in a team perhaps your allies could buy you time. Now, it seems we've learned what we set out for."

A blade of wind, something that didn't just tear apart everything. Many of his techniques simply annihilated everything without discrimination, which was not ideal in missions that included too many allies or wished to keep down the collateral damage,

"If you are satisfied, I believe we can go rest now. Shall we?"
Derek
"Yes. You will tell me more about what you think of war. You are the first person to speak of it with me." Regardless of if Tasturama agreed or not, Sadazane would follow the Senju around for a few hours after the training session, doing his best to absorb everything he could. 

Whether or not the information was useful to him would be up for the Genin to decide in time, even if alone in his apartment he elected to take the words his new master spoke to heart, slowly eroding and moulding the views Sadazane had into something different altogether.
