For the character of the Thousand Hands Pillar, Jiu Sinai is naturally no stranger.

The wooden ninja who pacified the troubled times, the first Hokage, the god of ninjas......

Compared with these ethereal, unrealistic names, Kushina is more familiar with him as the husband of Mito's grandmother.

Because although Kushina has never seen this one, she often hears Mito's grandmother counting her dead husband.

Said he was a bad gambler who stepped on two boats.

However, she could still capture the deep nostalgia in her grandmother's eyes when she said these words.

Kushina, who came back to his senses, took the card and continued to study.

Names and descriptions aside, what do these "costs", "attack power", and "health" mean, and what do they have to do with the runes above?

Jiu Sinai was puzzled, and simply picked up a few more cards to read.

Sarutobi Sasuke, Hinata Tenshinobi, Madara Uchiha, Ryoto, White Lotus, First Ai, Ishikawa......

Obviously, they are all legendary ninjas who were active in the troubled times of the Warring States, and even the former patriarch of the Uzumaki clan, Uzumaki Ashina, also appeared in it.

In addition, there are also cards that introduce ninjutsu, illusions, and physical arts, and also have those words of unknown meaning on them.

Jiu Sinai couldn't hold back the curiosity in her heart, and asked Xia Yan directly: "What is the use of these cards?" ”

Seeing that she was so anxious, Xia Yan stopped selling Guan Zi and gave a simple and clear answer.

"Play."

"Play?"

Seeing that Jiu Xinnai's head still hadn't turned, Xia Yan had no choice but to explain:

"That's right, it's not really anything advanced, it's just that I combined the practice of drawing runes with a little game to see if I could make the boring practice more interesting."

After listening to Xia Yan's words, Jiu Sinai couldn't help but think of those character introductions and Xia Yan's projection technique, and suddenly had an idea.

"Could it be that if you complete the rune technique, the character projection corresponding to the card will appear?"

Xia Yan nodded to indicate that she had guessed correctly.

Kushina grinned, a little smug.

At the same time, it quickly occurred to her that this game was indeed quite interesting for the little ninjas.

It is enough as a teaching aid to motivate everyone to learn.

And after learning about Xia Yan's idea, Jiu Sinai suddenly had a sense of déjà vu, and his fingers lightly patted his head.

"How did I forget this?"

"When I first started learning sealing, Grandma Mito used to make similar things for me, as long as I filled in the vacant runes, the rune paper would fold itself into various origami toys, which was fun!"

In retrospect, it was a painful and happy time.

And these cards made by Natsuhiko are not exactly the same as Mito's grandmother's origami?

Is this the brain circuit of geniuses?

The new one is shivering. JPG

Jiu Sinai looked at Xia Yan with mixed feelings, a little envious.

"I didn't expect Mito-sama to have the same thoughts as me."

Natsuhiko couldn't help but raise his eyebrows after hearing Mito's operation, a little surprised.

But what really surprised him was that Kushina actually used normal rune paper to practice drawing runes, otherwise it would not have been possible to successfully cast the spell and turn it into origami.

It's really rich~

Xia Yan has always felt that even if there is a mine at home, he can't afford to practice like this.

I didn't expect to be slapped in the face here, and I was shown off by Jiu Sinai's unintentional Versailles.

Sure enough, it was poverty that limited his imagination.

It's good to be rich~

Xia Yan looked at Jiu Sinai with mixed feelings, a little envious.

For a while, the two looked at each other deeply, and there was no trace of impurity in their eyes, only the deep envy of the scumbag for the scholar and the poor ghost for the rich woman.

But soon the two of them looked at each other strangely.

Because Kushina suddenly thought of another question.

"But Xia Yan, these runes shouldn't be able to complete the spell, right?"

Although the projection technique is said to be only a combination of the simplest doppelganger technique and the transformation technique, it is not very difficult.

But such a shoddy rune paper still can't withstand its toss.

Xia Yan also came back to his senses and said with a mysterious expression: "Because it's not these cards that are really used to cast spells. ”

As he spoke, he picked up one of the two strange wooden machines he had just taken out.

Under Kushina's gaze, Natsuhiko put his wrist on the disc part of the machine, and it could be seen that after wearing it, a sickle-shaped plate extending outward from the disc disc was just parallel to his arm, and it did not affect his movement.

There are also a few square grooves on the top of the tablet, which are exactly the same size as those cards.

As soon as Xia Yan put on the machine, he felt that his soul of middle two began to burn.

However, he quickly suppressed it and explained to Kushinai:

"This dueling board is the key to turning those cards into magic."

Yes, the "duel plate" in Xia Yan's mouth is actually very similar to the one that appeared in "Yu-Gi-Oh", but there is no transformation function for the time being, and it is in an expanded state from the beginning.

However, the mini-game that Xia Yan said before is not an imitation of Yu-Gi-Oh's gameplay.

After all, he just wanted to use this game to make the little ninjas less resistant to practicing drawing runes.

I didn't plan to make them hardcore players and spend too much time on this game.

Otherwise, he wouldn't even be able to pass the level of the Vice Principal.

Therefore, compared to the Yu-Gi-Oh with more cumbersome rules, Xia Yan still chose the easy-to-learn Hearthstone as a template, and used the characters of the troubled times of the Warring States as characters to create such a card game.

And the name is to touch the light of the card game that swept the ninja world in Boruto, so it is also called "Fierce Ninja".

Kushina was a little surprised when she heard that the dueling disc was actually related to those cards.

"So these two things aren't weapons?"

She was actually a little concerned about these two strange machines just now.

But because they looked like weapons, she didn't dare ask.

As a result, I didn't expect them to be related to the game that Xia Yan said!

Kushina's words made Natsuhiko want to laugh a little.

"If it's really weapons, then why did I put them next to those cards?"

"Probably...... Is it to save space? Kushina said weakly, "After all, they do look like weapons." ”

"How can it be ......" Xia Yan's first reaction was to refute.

How can this thing be used as a weapon?

I summon a dueling disc to present an attack indication and perform a direct attack on the opponent?

However, when Jiu Sinai said this, Xia Yan still subconsciously looked at the duel plate on his wrist.

Hey, don't say it, it's really quite similar!

Putting aside his mindset, Xia Yan felt that this dueling disc looked very similar to the Odaqi blade that appeared in the World of Warcraft, or it could also be compared to the Oriental stick with a blade.

It's just that they are held in the hand, and the dueling disc is worn on the wrist.

Why haven't I ever thought that way before? I'm afraid that thousands of episodes of "Yu-Gi-Oh" are not in vain!

Because of his habitual thinking, Xia Yan only thought about treating it as a toy before, and didn't think about weaponizing it at all!

Reminded by Jiu Sinai, Xia Yan's brain opened up for a while, and inspiration surged like a spring.

Duel disc plus Odaqi Battle Blade, did you make a head?

If the ninjutsu used in actual combat is drawn on the card in the form of runes, it is selected according to the situation......

If you add a blade to the edge of the dueling plate, no, you can make a chakra knife directly with chakra metal......

Or directly make it in the form of gauntlets to strengthen the ability to break the shield......

……

An unprecedented weapon quickly took shape in Natsuhiko's conception......

At this time, Jiu Sinai didn't know that his casual words would lead to the birth of a new profession in the future.

They wield a terrifying weapon called the Combat Duel Disc and a new way of fighting while playing cards and beating people, which terrified the entire ninja world.

Because they are considered by the world to have gone against the right path of card games and walked in darkness.

To distinguish itself from players who play regular card games.

Later people called these people ...... Dark Duelist.
