Sarutobi Hiruzen was confused, he hold the Book of Seal for somlong but he never see or read such agreement.
But still, he want to see what kind of agreement he talking about so he ask stand up and summon a huge scroll in front of them.
"This is the Book of Seal?"
"Never see the real thing."
"I heard it contains Forbidden Jutsu that Second Hokage made in his lifetime."
"I know right, I heard that if you made a huge achievement you can get a chance to choose one S Class Technique inside."
Sarutobi Hiruzen can't help but to feel proud seeing the jealous and envy of everyone after he summon the Book of Seal, but what confused him is that, Xin never change expression when he summon it.
Shaking his head, he show it to him and asked." What page the Agreement written?"
Xin look at the Book of Seal, then to Sarutobi Hiruzen with intriguing expression making Sarutobi Hiruzen broke a sweat suddenly.
"You are funny Third Hokage."
"... What so you mean Prince Xin?"
"Book of Seal contained all Senju Tobirama's Forbidden Jutsu and other powerful Jutsu thos epast Shinobi created."
"Book of Seal is one of the important weapon of the village, it was so important to that only Hokage can hold it and read it, but I never expect you did such stupid thing."
"Pardon me Princes Xin, I don't really understand what you saying." Sarutobi Hiruzen coldly said.
Xin pointed the huge scroll and said." That Book to Seal contains the Technique but not the Agreement."
"What so you mean? You said that Agreement is inside of the a Book of Seal right? Why you said there's no written Agreement inside of this?" Danzo asked.
"Simple, the Book of Seal you showing us is just a copy of Book of Seal, what makes me confused is, the Book of Seal is dangerous and also important, such thing should be unique and no second copy should appear."
"So here is the question, who made the second copy when having one is already hard to hide form the eyes of the enemy?"
Everyone finally snap out, that's right, the Book of Seal is unique, it was also the weapon of the Village and contain the Heritage of the whole Village inside.
If the Book of Seal is copy, then the uniqueness of the book is finally gone while the danger of getting the book by the enemy become higher.
Sarutobi Hiruzen finally realized the stupid thing he did, he know and everyone in the Elder Group know that they can't create a second copy of the Book of Seal as their teacher order.
This is dangerous move, crating a copy show that the Book of Seal can be copied and reproduce couple of times.
Without a second thought, Sarutobi Hiruzen throw the book, he hand seal then spit a ball of fire.
"Fire Release: Giant Fireball Technique!"
Boom!
The Book of Seal hit by the giant fireball and burn it to crisps making everyone finally snap out.
Looking at the brining copy of the Book of Seal, no one feel envy or greed at all, they know that having a copy made the important heritage of the village even more hot in the eye of the enemy.
But what they not know is that, the three Elder who watching is sweating hard right now, after all, each one of them has the same copy of the Book of Seal back home.
No one know how and when but they all have a copy, Danzo even have more copy on his hand using it by the Root freely.
"Now the 'last' copy is gone, can you finally take out the real Book of Seal?"
'He know!' The Elder Group can't help but to tremble, they know holding Book of Seal and storing it on their Clan can bring them and their family to death.
After all, Book of Seal can only hold and read by the Hokage, and even they are the highest and second only to the Hokage, they hey still don't have any right to hold it or even more having a copy.
