The Bad Works of Comics

Tongzi is made with homemade soy sauce in the kitchen, and then poured on the cooked sashimi, and the charming aroma immediately wafts in the room.

smell good!Misaka really wanted to taste it.

The last work showed a moved face and kept moving his nose.

Yui next to him is also eager to try, it seems that the delicious temptation is really too big.

Although it is said to be freshwater fish, it tastes like the oily yellowtail that is in season.

According to Tongzi, this is a species that cannot be caught if the fishing skill is less than 950.

In this way, Misaka chatted with her for a while, then concentrated on moving the chopsticks in his hand.

The plates on the table were immediately cleared by the girls present.

…………

After the meal, Kiriko thanked Asuna and The Last Work with a cup of hot tea in her hand.

"It's so delicious, it's been a long time since I've had such delicious food! Thank you so much for your hospitality."

"There. If there is no soy sauce that Ms. Kiriko goes with, I can't cook delicious fish fillets."

Asuna said to Kiriko very modestly.

"Hey... yeah."

Tongzi scratched her black hair embarrassingly, and said, "If you want, I can give you the recipe for soy sauce."

"Eh... is it really possible?" Asuna showed expectant eyes.

"Of course."

Tongzi nodded with a smile.

Chapter 187 Chapter 140 IX How could my Kirito be a black long straight girl?

After the delicious sashimi dinner, Tongzi happily played a small game of building blocks with Yui sauce.

"...Ah." Following Kiriko's voice.

The building blocks that had just reached the top collapsed.

...Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!

Tongzi screamed in her heart.

In fact, she never succeeded in this game.

Humans always have things they are good at and things they are not good at.

If you are not good at something, no matter how hard you try, it will be in vain.This is Tongzi's way of survival.

"Really, it was almost there. Misaka showed a regretful expression."

The last work, as an audience watching the whole process, can't help but feel sorry for Tongzi.

Tongzi nodded, sighed helplessly, and said,

"Hey... Well, I'm not very good at this kind of balance game."

"Sister Tongzi, look. It's almost like this."

After a while, Yui used the building blocks of different sizes in his hand to build out the Tokyo Tower, which is about one meter long and has a pillar supporting the sky.

"Ugh, so tall! Yui, you are really amazing!"

Looking at the Tokyo Tower in front of her, Tongzi clapped her hands and praised her.

"It seems that Yui has a talent for building blocks! Misaka put her two palms together, tilted her head slightly, and looked at the Tokyo Tower built with blocks in front of her."

"Is this difficult?" Yui tilted her head, looking puzzled.

Tongzi froze for a moment.

It's a bit shocking.

However, just looking at Yui's innocent eyes, it's really, really makes me feel uneasy.

Tongzi thought for a while, then said with a sad face,

"It's not difficult...but, well, Yui, sister, I'm not very good at playing with blocks."

"Otherwise, let's play a jigsaw puzzle together. Misaka raised her hand suddenly and said."

The last one raised his hand.

"Jigsaw puzzle?" Tongzi looked at the last work.

"Just now, Ms. Kiriko, you didn't say that you are not good at this kind of balance game. If that's the case, Misaka suggested that we play puzzle games together! Misaka explained, revealing her nature of watching the scene."

In other words, the last sentence is your focus!Tongzi couldn't help complaining secretly in her heart.

"this?"

Tongzi hesitated.

"Sister Tongzi, do you want to play with Yui?" Yui was already holding a box of puzzles in her hand, and she looked at Tongzi with cute little eyes.

"Okay, let's play jigsaw puzzles!" Seeing Yui's expectant eyes, Tongzi nodded helplessly.

The picture of the puzzle is a high-rise building, because of the symmetry of the high-rise buildings, there are many similar places.

Tongzi observed the picture, memorized some differences in the picture, and then prepared to start looking for puzzle pieces.

Generally speaking, jigsaw puzzles start from the corners, first look for highly prominent pieces, and find the similarities between them.

First of all, find an easily identifiable fragment, the stairs under the building, which is the key point.

Soon Tongzi's first and second jigsaw puzzles were assembled.

But there are too many identical and similar fragments of buildings, just like the stars in the sky, and the pictures in my memory are almost all the same glass on the buildings, with only very slight differences, although Tongzi can distinguish it with her five senses, it is extremely difficult. waste time.

However, she is ready for a protracted battle. Even after 3 minutes, Tongzi has not figured it out, but she is not discouraged at all, she is as motionless as a sculpture, because she believes that if you observe carefully, you will find subtle differences The place.

Sure enough, she found something different, it was the figure reflected in the building, well, find a different position on the corner of the edge, and then peeled off the cocoons bit by bit, Tongzi slowly assembled the pieces.

Finally, after 5 minutes, a jigsaw puzzle of towering high-rise buildings was completed.

"Miss Kiriko finished it so quickly. It's not bad! Misaka Misaka said with her head tilted."

The last work is lying on the table with its upper body lying on its head, with the hair on its head swaying, holding a completed jigsaw puzzle with tung seeds.

"It's okay!" Tongzi scratched her hair and said modestly.

"Then it's up to you, Yui-chan, Misaka said with a smile."

The last work messed up the pieces of the puzzle, and after confirming that they were correct, it was handed over to Yui.

"Okay! Mama Misaka!" Yui was already eager to try.

I saw that Yui calmly put the puzzle pieces aside in a certain order, and then slowly began to put them together.

Under Tongzi's unbelievable eyes, Yui spent ten seconds, 20 seconds... in less than half a minute, and completed all the puzzles.

"It's finished so quickly!" Looking at the [-]% complete puzzle, Tongzi looked surprised.

This makes Tongzi, who considers himself a game master, a little bit embarrassing.

"Well, this is actually very simple. As long as two numbers in a permutation are exchanged, the parity of the permutation will change. According to theoretical speculation, a whole jigsaw puzzle can be quickly completed."

"What do you mean?" Tongzi expressed a confused face.

"In fact, this is the case. We regard the blanks on the puzzle as the number 9, and look at picture a in the normal order. The arrangement of 9 numbers is 123456789, and its reverse order number is 0, which is an even arrangement; picture b is 123456879, and the reverse order number is 1. , is an odd permutation.

We know that we can only move 9, and the movement here is equivalent to a special swap. "

Yui paused, and began to explain slowly.

"Now assuming that the image b has changed to image a through a series of translations, then the space block 9 must be moved (swapped) an even number of times (one time to the left must be returned to the right again, and one time to be up must be down and back again) , according to the above theorem, the final arrangement must be an odd arrangement (same as picture b), but picture a is an even arrangement, which creates a contradiction, so it is impossible for picture b to become the final picture a by translating the blank blocks.

Considering further, picture a can be translated into some other states. We classify these into one category, and picture b also represents one category. Now we have to ask "How many categories are there in total?"

"It looks like there should be two types!"

Although what Yui said was a bit complicated, Tongzi still answered it.

Yui nodded and continued to explain to Tongzi,

"That's right, the answer is that there are only two types of puzzles greater than or equal to 2*2. So I got three points,

1.According to the above theorem, all puzzles can be divided into at least two categories

2. There are only two types of 2*2 puzzles

3.After the puzzle is enlarged, the number of categories does not increase.

According to these three items, it can be concluded that there are only two types of puzzles.We can get some other interesting results. The difference between the two types of puzzles is the odd number of swaps between them. That is to say, if a non-empty piece of a puzzle is swapped for an odd number of times, it will become another type.

The essential reason for being divided into two categories is because the plane has two sides, just like clockwise and counterclockwise.Because it is speculated based on the above analysis, it can speed up the efficiency of completing the puzzle pieces, you know?Sister Tongzi.

"

"Uh, this...

"Tongzi smiled awkwardly.

Yui-chan's mind became more and more confused.I thought that knowing the truth about the speed of the jigsaw puzzle would clear my mind, but unexpectedly, it has the opposite effect.

So, I can't learn this special skill of a master, I can't learn it!At this moment, Tongzi wailed in her heart.

"By the way, as a reward, my sister gave you something."

In order to change the subject, Kiriko visualized a fluffy frog from the backpack and handed it to Yui.

Item: +1s Frog?

Attributes: An ornamental furry toy, said to have some kind of power to manipulate time.

"...Thank you, Kiriko-san!"

Yui touched the frog doll fondly, and said something sweet.

"I didn't expect Miss Kiriko and Yui-chan to get along so well!" At this time, Asuna who came over with hot tea joked.

"Yeah! Yui-chan is very cute, just like my sister." Tongzi said with a faint happy smile on her lips.

"Oh? Kiri, Kiri-san, and a younger sister? How about it? Misaka asked curiously."

The last work came over to the side, as if he had discovered something wonderful, he was even more excited than he imagined, and the dull hair on his head was shaking from side to side.

After a little hesitation, Tongzi answered honestly: "...Actually, our relationship is not as good as everyone thinks, because we were not sisters at the beginning..."

"Eh?"

Asuna was a little perplexed by Kiriko's words.

The last work shook the dumb hair on his head, his voice was full of confusion and incomprehension.

Nodding, Tongzi spoke intermittently.

"Although she is said to be a younger sister, she is actually a cousin. Suguha, she is very strong and cute. For some reason, we have lived together since Suguha was born, so Suguha shouldn't know about it. But , probably because of this... I want to keep a distance from her, and avoid meeting her at home."

Suguha's name is very cute, but Misaka is somewhat familiar!Is it an illusion?

The last work tilted his head and thought.

At this time, Tongzi sighed softly and continued.

"...Moreover, my grandfather was a very strict person. When I was eight years old, he forced me and my younger sister Suguha to go to a nearby dojo to learn kendo. I couldn't adapt to anything, so I gave up after two years. I was beaten by my grandfather because of it. At that time, my younger sister Suguha cried and said: "I will work harder, so don't fight anymore." to protect me. After that, I began to indulge in the world of computers, and my younger sister really Dedicated to kendo, not long before his grandfather passed away, he even got a good ranking in the whole country. Grandpa should be very satisfied... so I always feel that I can't compare with her. In fact, she should have other things that she wants to do, and she should hate it Me. Thinking about it this way, I unconsciously want to avoid her even more..."

"Plus, my sister is in a sports club, and what she hates the most is games. People like us don't interact with her at all. Compared to that kind of thing... that's how I came here."
