I am invincible when I signed silently in Naruto

Chapter 184 Strange Orange Aroma
The sudden operation almost made Tsunade jump, and he was immediately stunned.

In today's chaotic situation, what Konoha needs most is to recuperate in case of possible crises in the future.

And the Nine Tails in Naruto's body is the unstable factor.

The purpose of the 'Xiao' organization is to capture tailed beasts, and the Nine Tails will inevitably be their ultimate goal.

Even if the attack of the "Xiao" organization was repelled last time, there is no guarantee that the "Xiao" organization will make a comeback with great fanfare next time.

After all, Nine-Tails is the most powerful of the Nine-Tails, otherwise the village would not have been hit hard because of Nine-Tails' madness more than ten years ago.

Although it is not clear what the purpose of the 'Akatsuki' organization to capture the tailed beast is, but as long as the nine tails belong to Konoha, Konoha will never be able to back down.

Not only to protect the property of the village, but also to protect the safety of the villagers and Naruto.

This is the responsibility of being Hokage.

After becoming Hokage, Tsunade deeply felt the burden that Hokage needs to bear.

It turned out that her grandfather had borne so much for Konoha.

These things can only be felt after experiencing it for yourself.

But there was one more point that made Tsunade doubtful.

That's why Yunhe suddenly wanted to join the 'Xiao' organization.

Although this brat is not very reassuring, he will definitely not be careless.

So there must be a purpose there.

And this purpose is likely to affect the next structure of the ninja world.

I don't know why, but Tsunade has such an intuition.

Thinking of this, she hurriedly rummaged through the drawer and took out the letter Yunhe left behind, preparing to read it again carefully.

If there was any clue, it must be in this letter.

Although the content of the letter was only a few words, Tsunade saw that she was almost able to memorize them, but she still planned to look for other points that were missed.

After all, he wouldn't just leave a letter for no reason and leave. If he had something to leave, he would definitely say hello to her first.

What's more, it is such a big thing to join the 'Xiao' organization.

Therefore, this letter must have its mystery.

Opening the envelope, the contents on the thin letter paper immediately came into view.

[Sister Tsunade, when you read this letter, I think Iroha and I have already left Konoha Village and are on our way to the Akatsuki organization.

I wanted to say hello to you before I left, but now that you are busy as Hokage, I thought about not disturbing you, so I specially left this letter.

Iroha and I left this time to join the 'Akatsuki' organization. I can't tell you the specific reason, but we will not do anything that harms the interests of the village. Please rest assured.

So you don't have to send people to chase us back, we'll be back in a few days after finishing the work in the 'Xiao' organization.

your dear brother:

Yunhe]

There is only so much content in the letter, and it won't take long to read it all.

But no matter how many times Tsunade read it, he still didn't see anything unique from these short texts.

Whether it is Tibetan acronym, or Morse code, there is no such thing.

It's just an ordinary letter, as if it's just to save myself from worrying.

Tsunade Liu frowned, and read the contents of the letter several times, but still found nothing.

Just when she was about to give up, the faint orange aroma in the air caught her attention.

The smell is very light, so faint that it hardly attracts anyone's attention.

Especially since the smell was similar to the scent on Iroha's body, Tsunade subconsciously ignored this point.

After all, it looks like Iroha wrote this elegant font, so it is not surprising that there is her fragrance on the letter paper.

After all, in Tsunade's perception, these two people have been getting tired of being together all day long, so it's normal for Yunhe, a brat, to ask Caiyu to write letters for him.

But thinking about it now, this faint citrus fragrance seems to be slightly different from the fragrance on Iroha's body.

In addition to freshness, there is a sweet and sour taste, more like the aroma of lemon.

Citrus aromas and lemon aromas, although they smell similar in taste, are actually very different.

Those stinky men might not be able to tell the difference, but how could Tsunade not be able to tell the difference?

It was just subconsciously ignored before.

After all, she is a woman, and she is also a big beauty.

Especially as a beautiful doctor, she is naturally the most sensitive to these scents.

Now, if you smell it carefully, you can easily tell it apart.

The problem must be with this lemon scent!

Until then, Tsunade finally recalled a little thing from the past.

That was many years ago, when she was young...

Pooh!slip of the tongue!

Still young now.

At that time, Yunhe was only eight or nine years old, but he had already shown a maturity far beyond his peers.

At his age, he was supposed to be studying at the ninja school, but because of his past excellence, he graduated early and joined Anbe.

At that time, Yunhe once showed Tsunade a method of encrypted communication, which was to use lemon juice to write letters.

A letter written with lemon juice will not leave any writing on the letter paper, but as long as it is lightly roasted with fire, the content of the letter will be displayed.

This is a very primitive method of encrypted communication, but it is very effective.

And it doesn't have to be lemon juice. In the wild, there are many plant juices that can be substituted, and you can choose according to local conditions.

Then double encryption or even triple encryption can be performed on the stationery, so that the contents of the letter can be more securely protected.

But let's not mention this for now.

Now the protagonist is this wordless letter.

As a medical ninja, Tsunade knows that writing letters with lemon juice is realistic, but he doesn't know the specific principle.

After all, for a ninja, it is enough that this thing is easy to use, and what is the use of knowing the specific principles if it is not a ninja?

At that time, Yunhe explained to her very seriously, and said that he should believe in science.

But Tsunade still doesn't understand what science is.

But she remembered what Yunhe said.

What is it about?

Tsunade racked his brains to recall that difficult noun.

match...

Cellulol!
right!It is cellulol!
The stinky boy Yunhe said that because lemon juice contains an ingredient called cellulol.

As long as you write a letter with lemon juice, you can reduce the ignition point of the paper.

Then bake it with fire, and the characters that had disappeared will appear.

He also said that it is called a carbonization reaction, which is related to the composition of the paper. If a scroll or other materials are used, it will have no effect.

Because the paper contains starch.

When in contact with iodine, a chemical reaction occurs to form starch molecules, which give it its dark blue color.

When in contact with lemon juice, because lemon juice is rich in vitamin C, vitamin C reacts with iodine to produce a colorless effect.

So when you write a letter with lemon juice, you can create a wordless scripture.
