My Little Sister Cute Outside, But Yandere Inside!
Chapter 77 - Little Jokes for the Eyes

I walked into the Academy, in which appeared several young girls were on the move. The clothes they wore were wearing full uniforms and weapons.

This makes me wonder a little, is this Academy only filled by women?

As far as I can see, there are no men in it.

“Vivi, who's on duty tonight?” ask me.

“If not mistaken, Zilvi is in charge of teaching cryptography.”

Taking care of the intelligence unit is not an easy matter, they need basic knowledge to extract information and send that information to the headquarters in a form that is not understood by the opponent. Cryptographic techniques are used to send confidential information, techniques such as these are often used by other kingdoms. In contrast to other empires, our cryptographic techniques use an enhanced enigma machine.

Our enigma machine uses number and letter substitution encryption, using the same rotor but there are additional uses of wiring and magic-signature. By adding magic-signature, the number of words produced has more complicated variations and is very difficult to guess. Well. I'm not sure if this machine will be safe, but for now.enigma machine has an important role to protect our spy information.

When technology is developed along with magic, that technology will rise by one level.

I arrived at one of the classes and heard Zilvi's voice explaining the importance of communication using a special password.

Suddenly..a stupid question sounded in my ears, “Why should we use a password to communicate? Isn't relaying information by voice call much faster?”

Zilvi answered calmly, “A good question, but. are you sure you are alone? For those of us who have wolf ears.Your little voice while whispering can be heard up to three layers of walls. Did you guys forget? Not only humans who live in this world.”

“But, why should we bother wiping out the information we got after it was reported?”

Hearing this second question, I subconsciously held my head and chuckled.

“This question, it looks like Master Karl will answer it. Even Master Karl laughed when he heard your question.”

Holy hooch! Don't try to lure me out!

I haven't finished laughing after hearing this plain stupidity!

I walked to the entrance and opened it, as the door opened.The gazes of the innocent girls who were inside the classroom were fixed towards me. They were surprised to see me in their class.

I slightly held back my smile to do a little bullying. The mood turned gripping and a little heavy. Tonight, a special lesson came!

Zilvi just fell silent and pointed at one of the girls sitting in the very back row. I immediately went to see him and looked him in the eye.

I watched her a little, this girl looks very innocent and cheerful. I've seen a girl like this before, a small innocence that doesn't understand the reality.

I pulled out my phone and connected it to the projector screen.

“The answer to your question is quite easy..What happens when information from an intelligence leak?”

“Well.. view this..”

I slightly confirmed my words and displayed a disgusting photo. The photo on the projector screen is an overview of the spy agency caught by the government.

The picture they saw was the reality that was happening in the Kingdom of Flora. The captured spies will be interrogated and they move to use the information they can to infiltrate the opposing kingdom.

Humanitarian crimes they committed also varied such as poisoning certain springs to destroy one region.

“Well.. how about this? What happens if you get caught? Of course, you will be tortured and become their toys. But.. what do they do if they get information from you?”

The little question I asked made the atmosphere even heavier.

“What are you thinking right now, it will come true!” say me.

Well. With this girl's innocence, I suppressed her a little with a psychological attack.

I don't know why.it feels so fun!

It was not in vain that I learned it!
