Inside the Seal Teacher's office.

Natsuhiko, who doesn't know what kind of bloody storm his invention will set off, is introducing Kushina to how to use cards and duel plates.

He first took out a card from his pocket and showed it to Kushina.

The runes that were supposed to be vacant on it have been filled in.

Then Natsuhiko slapped the card into the card slot on the dueling board.

A hearty male voice suddenly sounded in the office.

"People trust me...... I trust you too...... This...... It's the Hokage! ”

Without any warning, a figure of a man wearing red stacked armor and posing in a combat posture appeared in front of Xia Yan.

Although he was already mentally prepared, after seeing the man's appearance clearly, Jiu Sinai still opened his mouth slightly, a little surprised.

After all, this man's appearance was very similar to what she saw on Hokage Yan Rock every day.

Not bad!

This is the legendary god of ninjas...... A rotten gambler who also pedals on two boats - between the pillars of a thousand hands!

"This is the original Hokage...... What does grandpa look like? ”

After the surprise, Kushina's curiosity gradually got the upper hand, and she began to circle around the projection between the Thousand Hands Pillar.

Look east and west.

In the end, I even touched it, but unfortunately there was no suspense and I passed by directly.

Sure enough, it was just a phantom, not a substance.

After satisfying her curiosity, Kushina tilted her head and pointed her chin with her slender index finger to make a comment.

"Isn't it as handsome as I thought it would be? I don't know what Grandma Mito likes about him? ”

Feed! Kushina San! You've been studying this for so long?

Xia Yan couldn't help but twitch the corners of his mouth.

And where did your inexplicable hostility towards the original Hokage come from?

You haven't even met!

Seeing Xia Yan's strange expression, Jiu Sinai remembered what was going on, walked over to Xia Yan with a sigh, and checked the card that was slapped on the duel plate.

As a result, she was surprised to find that after using this card, the rune paper part was not damaged, but the runes that had been filled in before had disappeared.

"I see!"

Jiu Sinai suddenly Conan got up, a lightning bolt crossed his mind, and he suddenly realized.

"It's this ...... that really works projection The dueling board must have the corresponding rune spell drawn in it. The runes on the card only serve as a trigger function and do not participate in the formal construction of the spell, so even such inferior rune paper can withstand it and can be reused repeatedly! ”

She folded her hands and analyzed excitedly.

"It's not as exaggerated as reuse, and this usage will still cause damage to the rune paper. I've tested it about twenty times and then it starts to have problems, and after thirty times it's completely scrapped. ”

"And although I designed the chakra diversion circuit in the duel disc to make it more durable, the components inside will gradually wear out, and if you really calculate it, it can only reduce the material cost that students need to consume in the early days to about a quarter."

Natsuhiko corrected Kushina's statement, and then praised her again, "But the other places are not wrong, and they are worthy of being Mito-sama's disciples." ”

Ever since she knew that Kushina was an invisible rich woman, Natsuhiko decided to be gentle with her.

"No, you are amazing at thinking of Xia Yan who reuses rune paper in this way!" Jiu Sinai sighed.

"No, no, in fact, there are still many flaws in this method, for example, you can only practice a small section of rune techniques, and it is very powerful that you can understand it so quickly."

"No, no, no, I just thought of it according to Xia Yan's train of thought, and you who invented this method are geniuses."

"No, no, no, no......"

"No, no, no, no, no......"

……

"Okay, let's stop complimenting each other like this."

In order to end the meaningless humility, Xia Yan waved his hand and proposed, "Otherwise, we will use this game to divide the winners and losers, and whoever wins, the other party will be a real genius." ”

Isn't that a strange prize?

Kushina was tempted to complain, but her attention was quickly drawn to other words.

"Winner or loser?"

Kushina's eyes gradually widened: "Could it be that this game has other ways to play besides projecting characters?" ”

“……”

（─.─||）

Xia Yan was a little speechless.

So that's what you've been showing you all about this game, huh?

What kind of dung is this?

Even the games of the I company will not be just for players to watch! At least you can choose a pose!

Sure enough, the entertainment activities in the ninja world are too scarce, and even projecting a character is regarded as a fun game by her.

If there was such a toy that could only project characters in his previous life, he ......

Well, I guess it's going to be a big deal.

Then the projection of a tsunade hand came out, and you can sit on a stool and watch it for a day, which is beautiful.

Shaking his head and putting the strange thoughts behind him, Xia Yan spoke: "It's too troublesome to introduce, so let's just start a game to demonstrate." ”

"Okay!" Kushina nodded expectantly.

So Natsuhiko took out a deck of cards and handed it to Kushina along with another dueling disc on the table.

He himself took out the card between the Thousand Hands Pillar, and then led Kushina to a relatively empty corner of the office.

Then he took out another deck and inserted it into its position on the disc of the dueling disk.

Kushina did the same, and some hurriedly put on the dueling disc and inserted the deck.

After seeing that Jiu Sinai made an OK signal to be ready, Xia Yan explained: "In order to identify the object of the duel, the game needs to be started with two people shouting 'Duel' at the same time, which means duel. ”

"Then why don't you just use 'duel'?" Kushina asked.

“emmmm…… Because the word 'duel' is sometimes used in everyday life, it may be mistaken at that time......"

Xia Yan explained with some confidence, after all, he couldn't explain that he only designed it when the soul of the middle two exploded.

As a result, Jiu Sinai actually believed it and looked at Xia Yan with a sympathetic expression.

Natsuhiko, what kind of daily life did you live before?

Sure enough, the three generations of grandfathers told her that it was true, and the people outside the village were living in dire straits.

In order not to arouse Xia Yan's sad memories, Jiu Sinai hurriedly asked Xia Yan how to pronounce it.

So an improvised English class began.

“Duel！” Xia Yanzi said in a round voice.

"Lost?" Kushina tilted her head and imitated.

"It's Duel." Xia Yan corrected.

"Dou Wow?"

"It's Duel."

……

Ten minutes later.

"It seems that there will be a function that can identify opponents without voice control in the future."

Xia Yan wiped his sweat and muttered in his heart.

Fortunately, Kushina finally learned.

The two stood a few meters apart again, each concave a position, and shouted at the same time after counting down to three-two-one:

“Duel！！！”

The duel has officially begun!

As soon as the two finished speaking, Jiu Sinai saw a big number suddenly appear above Xia Yan's head: 20, and there was a virtual figure in the shape of a copper coin next to him.

She subconsciously looked up, and sure enough, she found that she also had the same thing on her head.

"The number above the head is the health of each player, and if it goes down to zero, you lose." Xia Yan began to explain.

"The copper coin next to it represents the cost of playing cards, and the maximum value of each round will increase by one point, up to a maximum of ten points, and at the end of each round it will be reset to zero if it is not used."

"You can think of players as daimyo who hire ninjas to fight, and copper coins are hired fees."

"Now let's draw five cards each."

After the two drew out five cards, Xia Yan said again: "When the duel begins, the duel disc will randomly decide the first hand, and this time I will be the first, just to show you." ”

"You can draw a card at the beginning of each turn, but for balance, you can't draw cards on the first turn."

Xia Yan glanced at the card in his hand, then pulled out one and slapped it on the dueling plate.

The next moment, a small figure of short stature, with the same silver curly hair as him, appeared in front of him.

【Yusheng Natsuhiko (Shimoshinobi)】

[Cost: 1, Attack 1, HP 2]

[No effect: I'm dragging my feet on the tissue again.] 】

[Introduction: Ordinary Shinobi, no one thought that he would become the inventor of this game in the future, and he also made himself into the game. 】

Burst~

Jiu Sinai felt a little familiar when she saw the silver curly hair for the first time, and after reading the introduction, she couldn't help but laugh.

"Xia Yan, why did you make yourself a card character?"

"No way, most historical figures aren't suitable for this kind of low-cost card." Xia Yan said helplessly, "Instead of making up a fiction, then I'll do it myself." ”

"Actually, I plan to make students into this game in the future, as a reward for the top few places in the sealing exam."

“……”

The interlocking design made Jiu Sinai unable to find the right words to describe Xia Yan for a while.

If you use Xia Yan's words in his last life, it is the old sow with bras - one set after another.

Xia Yan continued to explain:

"If you don't have a special effect, then it will take a turn for all units to attack, and then it's your turn."

After saying that, Xia Yan announced the end of the round.

"Great!" Kushina replied with a fist.

She had just finished watching Natsuhiko's demo and felt that the game was quite simple, so she confidently drew a card and began a pleasant journey of forbearance.

"It's my turn, gacha!"
