Sasuke narrows his eyes at Hashirama as he ask him question !
Sasuke: What is shinobi ?!, what is village ?!, tell me
Hashirama(smiles as he put his hand behind his head): you have interesting questions, young Uchiha
Tobirama: it looks like you didn't learn basics in Shinobi Academy I created, tsk...
Sasuke: ?!
Sasuke narrows his eyes at Tobirama with his eternal mangenkyou sharingan
Hashirama: ?!
Tobirama: It looks like you want to challenge me...
Tobirama takes one step forward as he is stopped by Hashirama.
Hashirama: Tobirama, calm down. Fight is not always solution
Tobirama: really, i wonder then why we have fought through our enteire life,

?
Hashirama(lower his head ): Tobirama
Suddenly Hashirama and Tobirama turns their head from themselves to Sasuke, as they sense powerfull chakra floating in air. Hashirama looks suprised as he notices full skeleton from of Sussano around Sasuke , while Tobirama take step back as he raise his hands to chest to form seal.
Sasuke: Silence !
Hashirama, Tobirama: ?! *That is Sussano*
Sasuke: Stop ignoring me, and you rather answer my questions because from it ,depends my decision about destruction of Konoha !
Hashirama: ?! *This is same as Madara and Izuna.*
Tobirama: ?! *Ehh.. Madara and Izuna... Sussano...., *
Tobirama(mad): How you dare ?!
Tobirama becomes mad as he prepare to fight but is stopped by Hashirama with his hand extended blocking Tobirama way. Tobirama turns his head to hashirama to protest then he notices change in attitude of Hashirama as well as his serious face expression.
Sasuke: ?!
Hashirama: Very well. I and my brother Tobirama were born in times of never ending wars, where shinobi was known as human who knows Ninjutsu or genjutsu or Taijutsu or all of them.
Flashback
As Hashirama talks, Hashirama and Tobirama childhood are shown, Tobirama and Hashirama training, Hashirama and Tobirama taking part in fight against other clan along with enteire Senjuu Clan supporting them. Minato and Hiruzen turn their heads to Hashirama who is talking, as they are smilling in his direction.
Flashback
Tobirama(nods): you are right , Hashirama.
Orochimaru(smirks): * I was right Jirayia *
Sasuke:

...
Hashirama: Although it is true, it doesn't give true meaning of Shinobi term. Shinobi is everyone who can protect your beloved ones, family and friends at cost of own death. Shinobi shouldn't was driven by only heart but they shouldn't exclude their heart from their lives too, however it can seems to be hard sometimes.
Flashback
Hashirama and Tobirama parents are shown in one of wars againt enemy's clan, as one of Senjuu is hit by enemy then fall down on ground badly injured. As enemy is about to give final blow to Senjuu shinobi , Hashirama's and Tobirama's mother and father saves him, then they decide to stop enemies while other shinobi from Senjuu clan will bring injured comrades to safe place.
Flashback
Sasuke: *reminds of Kakashi protecting team 7, Naruto protect Sakura, Sasuke wanted to protect Naruto, finally Itachi protecting Sasuke from shadows.* Indeed, this is true.
Tobirama: Although , this is right. Shinobi has to act as assasin sometimes. There is more dark aspects of being shinobi as well.
Hashirama: Sadly, Tobirama is quite right, but nevertheles shinobi can't and will never be killing machine, no matter how much he/she will try, we can't kill our emotions completly because we are humans so we make mistakes in our life, which we should accept and try our best to not repeat them. Shinobi will kill only for greater good and when has no other choice.
Flashback
Senjuu and Uchiha clan are shown, stopping fighting while each of them, clans take injured ones comrades to safe place. Other clans battles are shown, with many injured shinobi laying on ground as enemy didn't give final blow to them.
Flashback
Sasuke:

... *remember himself obsessed by revenge, Sasuke standing over Naruto in valley of the end after battle*, I know.
Tobirama: While emotions are needed I agree, it can flaw our take of hard decision. Shinobi has to endure pain, loss of beloved ones(lower his head for moment, then raise). You can't let your emotions affect your decission, for example ,your student left you village or is about, if he/she is dangerous then you have to be ready to kill them.
Sasuke(sadly look at ground): I know it , too.
Hiruzen(lower his head as he is thinking): *Orochimaru..., you was great student, but now you are my biggest failure..., sadly I wasn't able to kill you when time came.*
Hiruzen reminds Orochimaru as Child, genin, chounin, jounin, when he discovered his experiments, fought against him, and finally today.
Hashirama,Tobirama: just remeber true shinobi strength and worth awake only when they have to protect someone precious to them.
Sasuke: I got it... ok, what is village then ?!
