Vol 3 Chapter 512: If you want someone to say it, the big sister sitting here is not saved...

"Uh-Black Cat, don't give up, don't worry, I have an idea below."
"……what?"
Seeing Saori's self-confidence, Wugeng Liuli calmly took a sip of tea and said.
Although it doesn't report any expectations, it's not impossible to listen to it.
"Ahem, although it's just my humble opinion of Xia Xia, Xia Xia believes that the magic of magic is not because of the power of destruction in fantasy works, but because it [does not conform to the scientific theorem]. ."
"So?"
"Black Cat's, where did the dust that was removed when you performed your magic? The amount of dust in the entire football stadium should be quite large, right?"
"...Disappeared, completely gone."
"What about a closed environment? How can the dust in the box be removed?"
"...I don't know, it may have disappeared directly, or it may have been transformed into something else? My naked eyes can't confirm the existence of dust."
Speaking of which, not only Saori and Ruri Ohgeng, but even Yuuki who was patronizing Yuuki who was patronizing and eating, turned his attention.
"Heimao, do you know? Now because of the widespread use of quantum computers, quantum computers are particularly expensive. In a large data center computer room, the annual mechanical maintenance costs can reach hundreds of billions. The data loss caused by the mistakes of the United States and the economic losses caused are even more numerous..."
Listening to Saori's words, Wugeng Liuli seemed to understand something, thoughtfully.
"Although places like large public facilities or commercial office buildings spend a lot of money on dust removal and cleaning every year, this kind of work can be easily completed by taking some time with manpower and tools. It is almost impossible to use magic to do this kind of thing. It's waste.
However, the cleaning of high-precision tiny machinery in operation, the high-precision laboratory that requires Absolute Dust, and the closed environment Absolute Dust, some tasks are absolutely impossible based on the laws of mechanical physics, but magic turns them into may. "
"Oh, don't I know that the sterile room of the hospital is very troublesome to make? Although I don't know the details, wouldn't it be easy if there is the magic of this black cat?" Kirino raised his hand and spoke.
"No, Sister Tong Nai, the sterile room and the clean room are two completely different concepts, one allows micro-dust and no bacteria, and the other allows bacteria and no dust..." As a regular visitor of the sterile room, excellent Ji still knows a lot about this than Tong Nai, who has never been to the hospital several times.
"Ah, oh...Is that so? Yuuki is very knowledgeable and even cuter!"
"Sister Loli! You have enough, I want to call the police!"
Seeing that Gogeng Ruri was angry because Kirino interrupted her thinking, Saori and
"Ahem, Xiaotong Tong actually said something. The two concepts of sterile room and clean room have one thing in common, which is [gradual air cleanliness, but complete isolation. The technology of this earth cannot be completed], so the top upgrade versions of the two [White Room] and [Zone Room] do not yet exist."
"In other words, as long as I find a room that completes the internal circulation of air and is completely isolated from the outside world, if I perform the [Dust Removal Technique], I will be able to complete the [White Room] that only exists and in theory?" Geng Liuli understood what Saori thought.
"Right, that is it.
Black Cat, can accomplish things that technology cannot accomplish. Isn't [Dust Removal Technique] a great magic?
The protagonist in the fifth volume of the latest "Divine Comedy-Altaïr" "The Magician Says Something To Say", Mr. Disfort Cavendish has a famous saying..."
"[Making things that were originally impossible possible, this is magic.]"
Wugeng Liuli said this sentence first, then looked at the expression of comrades and looked at Saori affectionately.
Saori also looked at Wugeng Liuli with approval and satisfaction and touched her nose.
When the love is deep, everyone can understand each other's meaning without much language. This is a situation that only congenial partners can understand.
"These two people are not saved..."
Sitting aside watching the spark of resonance between the two, Kirino said that he could not understand the world:
"Let’s not mention the magical girl in the fourth volume. The fifth volume is basically a story about how a young idler old man pretends to be a pig and eats a tiger and fools young people. I really don’t know what's interesting... you say yes Right? Sister Yuuki?"
"Ok?--"
Yuuki, who had been concentrating on eating, raised her head and showed a cute questioning expression when Kirino called her name.
"Ah!-So cute! Sister Yuuki, come home with me tonight! -"
Seeing Yuuki's cute look, how can Kirino still suffer? She immediately turned into a crazy girl ~EbookFREE.me~ gasping heavily.
"Oh...Sister Tong Nai, people think you should be the one who is hopeless, right?"
Very helpless, Yuuki blocked Kirino's gasping mouth with a large piece of cream.
"Ah, so happy... TvT... Is this the legendary feeding?"
At this moment, Tong Nai felt that he was dead without regret.
"..."
No way, as the dual attributes of loicn and sister-in-law, Takasaka Kirinozuko belongs to the high-looking little loli and the younger sister Yuuki.
In the real world, Yuuki couldn't slash with a sword, so she could only turn her head and look at the scenery outside the window.
The four of them are here today to participate in a festival called the [door closing ceremony]. This celebration is to commemorate the [door] who appeared in Ginza for two full years and changed the basic understanding of the world of mankind, leading to The [Eve’s Gate] in another world was closed at 0:00 tonight, and it was a celebration ceremony held.
Although I don’t know why the town government should regard today as a national carnival festival, or why it should be celebrated in relevant or unrelated places throughout the country, it may be because the town government wants to eliminate it, as the outside world has said. [December The twenty-fourth is the day before Christmas] This kind of foreign cultural invasion may be because of something else.
However, these have nothing to do with their four underage girls. They just know that as the main venue [Ginza] 4-chome street is very lively today. There will be various parades and immigrants from other worlds. The alien race is about to show up today, so I decided to gather here for tea and snacks.
And it’s all thanks to the magical powers of [System Meow] to make reservations at this family restaurant with a good view on this busy day...
