It's an unfamiliar, never-before-heard system sound.

After this system sound fell, Ogata's brain shut down for a while before he finally came to his senses.

After coming to his senses, the first thought that came to Ogata's mind was that the function of this system is really more than just upgrades! And a lot of hidden features!

Previously, Ogata suspected that his system still had many hidden functions waiting for him to explore and unlock.

After the level of Sakakiwara Ichitorya reaches the 5th rank, a new feature is unlocked - after reaching a certain level in the martial arts genre, you can obtain exclusive skill points.

And now, by chance, Ogata unlocks the ...... No, I think I'm aware of a new hidden feature of the system.

The system sound only rang in his head once, so after coming to his senses, Ogata hurriedly focused his attention and put away the interface that asked him if he wanted to spend 1 skill point to unlock the "No Self Two Knife Flow".

Each interface of the system has three functions: open, fold and close.

Then he carefully recalled every paragraph of the system sound just now.

The first paragraph of the system sound just now is-"Successfully browsed all the sword skills of the Erdaoliu swordsmanship 'Wuself Erdaoliu', and successfully extracted the Erdaoliu swordsmanship - 'Wuself Erdaoliu'"

And the last paragraph - "Do you want to spend 1 skill point to unlock the Second Sword Flow Sword Technique - 'Selfless Two Sword Flow'"

- There is no doubt about it...... This hidden function of the system is related to the acquisition of new martial arts genres.

Ogata said in his heart.

- In order for the system to successfully extract a new martial art school, certain conditions should need to be met......

- And the first paragraph of the system sound just now should be a necessary condition for whether the system can successfully extract the martial arts school......

- "Successfully browsed all the sword skills of the 'Selfless Two Sword Streams'...... What does this passage mean......?

- Do you mean...... As long as you can read all the skills of a certain genre with your own eyes, whether you understand it or not, can the system help you extract this martial arts genre?

- I'm going to have to experiment......

Ogata pursed his lips and pondered for a moment.

Soon, he came up with a way to experiment.

"Misaki-sama!"

Ogata turned his head and shouted into the kitchen.

"Could you please come over for a moment?"

"It's coming, it's coming!"

As soon as Ogata's words fell, Asaki walked out of the kitchen with small steps.

"Ogata-sama, what's the matter?"

"Misaki, I remember you said - you know the women's self-defense technique that your family has passed down from generation to generation, right?"

"yes, yes. However, the women's self-defense technique that has been passed down from generation to generation in our family is just a very simple self-defense technique, only 3 simple tricks. ”

"That's right! And I remember you said you could write, right? ”

"yes."

Since becoming the "security guard" of the stream house, Ogata and Aki and Afu will chat together whenever they have time.

Through small talk with Aki, Ogata also learned a lot about Misaki and Fuku.

For example, Aki's mother's family is actually very good.

Although it is not a rich and noble family, it is also not worried about food and clothing.

Misaki's maiden family has a women's self-defense technique that has been passed down from generation to generation, and it also pays attention to education.

The daughter's Aki is not only literate, but also able to read and write—in the Edo period, it was very rare for a woman like Aki to be able to read and write.

"Misaki-sama! Can you describe all the 3 techniques of self-defense in a piece of paper in simple words what kind of tricks they are and how to learn them? ”

"The simpler the description, the better! Preferably the kind of simplicity that I can't understand! ”

"Yes, yes...... But Ogata-sama, what are you going to do here? If you want to learn my self-defense technique, I recommend that you don't...... Because my self-defense technique is only suitable for women, not for men. ”

"It's not that I want to learn your self-defense skills, but I have something important to confirm, please!"

"Okay......"

Although he didn't know what Ogata was going to do, out of trust in Ogata, Misaki quickly stepped into the back room of their drift house, and then came back with pen, ink, paper, and inkstone.

Misaki's self-defense technique only has 3 simple moves, and Misaki quickly followed Ogata's order and outlined in very simple words what each of her self-defense techniques looked like and how to learn it.

After Misaki finished writing, Ogata immediately picked it up and read it word by word.

Misaki did exactly what Ogata wanted.

The words used in Aki's introduction are so simple that Ogata can't even understand what he's talking about.

As Ogata went through every word on the paper, a long, familiar system sound suddenly sounded in his head.

【Ding! Successfully browsed all the martial arts of the hand-to-hand combat technique "Yusaki's Women's Self-Defense Technique"]

[Successfully extracted hand-to-hand fighting skills - "Yusaki's Women's Self-Defense Technique"]

[Detect all martial arts schools currently learned by the host......]

[The host has not yet learned the rest of the hand-to-hand combat skills]

[After acquiring the "Yusaki's Women's Self-Defense Technique", you can gain personal experience and martial arts experience after defeating or killing enemies with this hand-to-hand combat technique.]

[The host can spend 1 skill point to unlock the hand-to-hand combat skill - "Yusaki's Women's Self-Defense Technique"]

[Do you want to spend 1 skill point to unlock the hand-to-hand combat technique - "Yusaki's Women's Self-Defense Technique"]

- It's coming!

Listening to the sound of the system in his head, Ogata was excited.

- And so it was! As long as I browse through all the martial arts introductions and learning methods of a certain martial arts school, whether I understand it or not, the system can successfully extract this martial arts genre!

- So, let's move on to the next stage of experimentation!

Ogata puts down the paper in his hand and closes the screen that asks him if he wants to unlock the Yusaki Women's Self-Defense Technique.

"Miss Aki, could you please demonstrate each of your self-defense moves?"

"Yes, yes, but what are you going to do, Ogata-sama...... If you want to demonstrate my self-defense technique, you need someone to be my partner. ”

"No problem, I'll be your partner."

Ogata stood up and served as Aki's training partner.

Misaki took Ogata as the training object and personally demonstrated every move of her "Yusaki Woman's Self-Defense Technique".

Because she only has 3 moves in this self-defense technique, she quickly completed all the demonstrations.

After Aki's demonstration, a system sound sounded in Ogata's mind that was exactly the same as the system sound that had just sounded in his head:

【Ding! Successfully browsed all the martial arts of the hand-to-hand combat technique "Yusaki's Women's Self-Defense Technique"]

[Successfully extracted hand-to-hand fighting skills - "Yusaki's Women's Self-Defense Technique"]
