(Wednesday, April 17, 2013, noon; Club Activity Room)

After school at noon, Yuta Tomigashi and Yuroka Bird came to the club room as usual. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info It didn't take long for Tansheng Tani Mori Xia to come at this time on a rare trip, instead of being busy with various activities as usual.

"Dansheng Valley, you've been getting along well with Convex Shou these days. Yuta Tomigashi said, "That kid sticks to you all day long, and it's not always a prank like before." ”

"Okay...... Alas, I'm tired too. Although she was asked to use the title of 'Tansangaya-senpai' instead of 'Sen-sama' at school, she would come to the class to look for me at the end of almost every class, and you didn't see it. ”

"Why don't you just tell her not to do that?"

"That's what I did, and I told her that yesterday afternoon. Dansheng Tani Senxia pouted, "But as soon as the kid heard this, he was going to cry." That's extreme......"

"Sure enough, Mori-sama-chan likes Xiao Bumaru. Fennel walked into the activity room and said with a smile. Dansheng Gu Senxia glared at her fiercely and did not answer.

"By the way, don't you have any plans to run for the student council position? In that case, why don't you ask Kamoru for help? She's quite popular in her first year of high school. ”

"She probably wouldn't refuse what I proposed...... However, it always feels like it's not good to do this, like it's taking advantage of her. Well, forget it, anyway, the student council election is in a few weeks, let me think again. ”

"Kamoru is really good as a servant. Kotori Yurouka said in her usual cold tone, "If Mori-sama needs it, I can lend her to you temporarily." ”

"So everyone is here!" At this time, Ichishiki Makoto walked in with a big grin, "Eh, why didn't that little ghost come?"

"It's said there's something going on in the class. Anyway, are you ready for what you're going to talk about this Friday?"

"Ahh

"Ah...... Sure enough, you look like Sister Fennel. Yuta Tomigashi habitually rubbed his temples, his face full of helplessness, "It seems that I still have to gnaw on this damn vector field calculus operation." Well, Dansheng Valley ......"

"Huh?"

"The day after tomorrow, can you make a report at the conference instead of Liuhua?"

Dansheng Gu Senxia gave him a strange look, and then looked at the bird You Liuhua.

"Isn't the president of the association Rokkana?"

"I'm a creature that lives in the dark, and there's a great danger to show my head like this. Little Bird You Liuhua said coolly.

"Actually, it's just shy. Yuta Tomigashi glanced at her, and the other party's little face suddenly showed a touch of crimson.

"So, you're going to look for me?"

"No way. Although this kind of thing may make Liuhua exercise much better, this meeting is related to the survival of the association, and there is no room for mistakes. Yuta Tomigashi spread his hands, "There is obviously a formal event...... Ahem, it's pretty formal in nature anyway, don't worry about the details. Wouldn't it be a shame if it was just canceled?"

"Why does it have to be me?" said Dansheng Taniya Senxia with some dissatisfaction.

"Isshiki and Sister Fennel are unreliable. I occupy one of the two delegates' seats, and the other is not you, so do you want to let the Boss give a report? I don't think you want to see her spread the gospel of your Dark Scriptures at the conference?"

"Don't mention that!hmm...... It's not impossible, but have you ever thought about what to ask me to say?"

"This one...... I remember that there were a lot of botany and pharmacy books at home in Dansheng Valley, right? Is it okay to talk about that? Anyway, you and Nanamiya have done a lot of drug experiments, so you don't have to worry about running out of content to talk about. ”

"You...... Don't mention the past!" Dansheng Gu Sen Xia Qiao blushed, and then sighed, "Whew, forget it, it's okay to do this." ”

"So, did you say yes?"

"Hmm. After I went back on Saturday, I thought for a long time about whether it was necessary to be entangled in the second secondary disease......

Her gaze drifted out of the window, and from the side she looked slightly distracted.

"When I was Mori-sama, although I had a lot of names, like 'crystal potions' and the like, I did have a serious experiment with Nanamiya later. Now that I think about it, Nanamiya must have secretly asked Professor Akiyama for help at that time, otherwise our experiment would not have gone so smoothly. Hawkers, in a sense, that talent is the strongest middle two disease, it's just that he turned his second middle disease into motivation. ”

Yuta Tomigashi was silent. Lord Sen, why do you make me embarrassed by this? You have also done serious things, and I am a pure fool [Pitch Black Flame Messenger]......

I feel ashamed to think about it!

However, Akiyama Sora's kind of demon that belongs to the demons, so don't compare with him.

Thinking of this, Yuta Tomigashi secretly glanced at the bird Yurouka who was sitting quietly on the side. She was staring blankly at the table with her arms folded, not knowing what she was thinking. After noticing his eyes, the other party's face turned slightly red, and he shyly avoided his gaze.

(Wednesday, April 17, 2013, night; 2nd floor, Yuta Tomigashi)

"Calculus in Vector Fields...... How does this thing have anything to do with magic? second-order micro-business or something...... Alas, I died of a headache. ”

Yuta Tomigashi yawned and looked listlessly at the "Feynman Lecture Notes on Physics" in his hand. The day after tomorrow is the congress, but he still has no clue about the upcoming speech.

"Sure enough, you shouldn't skip to read the content of this part, there is no foundation at all. It's not as simple as you think......"

Just as he was drowsy, there was a rustling sound outside the window, and then a figure rushed in through the open window.

"Brave—" The girl affectionately wrapped her arms around his neck from behind him.

"Nanamiya, let go of your hand. Yuta Tomigashi turned his head and said to her, and the other party let go of his arms.

"Babble, I'm sorry, I'm sorry, I accidentally forgot about it. Nanamiya Zhiyin scratched his hair and looked full of vitality, "The brave seems to be in trouble, let me Sophia help you solve it!"

"Do you have any suggestions from the Seven Palaces?"

"Well, well, vector field calculus or something......" she stuck out her tongue cutely, "I don't understand it either! Why not change it?"

"That being said, ......," Tomigashi said, raising the book in his hand, "nothing else has anything to do with magic." ”

Nanamiya Tomoin snatched the book from his hand, then proudly pulled out "Fluid Mechanics" from his satchel and said, "Look at this - a simulation of the ultimate magic of the [Black Flame Messenger]!"

"Huh?"

"Anyway, there are already relevant studies in the current world, and you only need to adjust the parameters in mathematical modeling. The wind and fire mages in the Academy of Magic use the [Wave Tube] to create overpressure airflow and study the combustion and explosion reactions in the air. ”

Tomoon Nanamiya pulled out the document from the pages and spread it out on the desk.

"The current experimental data is only 4 kilograms of TNT equivalent air cannon experiments, and a shock wave with an intensity of 410 kPa and a duration of 2.5 milliseconds was measured at a distance of 2.24 meters from the casting point. However, if the brave pushes the [Pitch Black Flame] with all his might, it is already infinitely close to the power of Level 9, which is equivalent to at least 100 kilograms of TNT, right?"

"This one...... Do you really want to talk about such things on stage?" Yuta Tomigashi's face was slightly red, and he was about to change the topic when the bedroom door was opened.

"Yuta...... What are you doing?" said the little bird, You Liuhua, walked in and stared at them with an unkind expression.

"Is the [Evil King's True Eye] here too?" "Nanamiya Zhiyin left him and ran to the side of the little bird You Liuhua, "I just thought of a way to calculate the ultimate magic of the [Dark Flame Envoy]!"

"Eh, what kind of method is it?" The little bird You Liuhua's interest was aroused, and he didn't care about the previous matter, "I'll take a look, I'll see!"

"For a given pressure ratio, different compression methods will produce different temperatures and densities, and the result can be calculated analytically for gases that do not undergo chemical reactions. Nanamiya Tomoyin pointed to a large section of text and formula in the book, "The Brave's [Pitch Black Flame] is a special power that does not react with air, so the calculation method here can be applied. ”

The little bird You Liuhua frowned a little distressedly, touched her chin unconsciously with her right hand, and muttered, "What does this symbol mean...... Hmm, how do you calculate this thing......"

"Haha! I've thought of this question for a long time, because I can't do it!" Nanamiya Tomoin pointed to the laptop on the desk, "Can the brave lend me a computer temporarily?"

"Well, let's use it. ”

Nanamiya deftly opened the browser, typed in a long list of addresses, and pressed enter, arriving at a web page that appeared to be some kind of simulation software.

"It's okay to enter the parameters here, it's just a rough calculation anyway. ”

After calculation, the [Pitch Black Flame Messenger] ultimate magic can generate extremely powerful shockwaves, which can be as strong as 10,000kpa within 3 meters, 2,500kpa within 5 meters, and can maintain a strength of more than 100kpa even from 15 meters away.

Ahem, if it really exists.

"This power is infinitely close to level 9, right?" Nanamiya Tomoin said excitedly.

"Don't forget, Yuta's [Black Flame] also comes with heat damage and dark corrosion. Little Bird You Liuhua added solemnly, "I think all things considered, this power can be called a leader even in Level 9!"

The two middle two girls looked at Yuta Tomigashi together, and there were colorful ripples in their beautiful eyes.

"Yuta (Brave), it's amazing!"

Tomigashi Yong wanted to cry without tears, thinking about whether to buy a piece of tofu and kill him. Looking at this posture, I have to talk about this at the conference...... Is this a stone to shoot yourself in the foot? I didn't mention any analysis of [Pitch Black Flame] to them before I knew it!

"Now, brave man, I'll go back first. Nanamiya Tomoon beckoned to him and climbed back to the third floor along the rope from the balcony.

After she left, Yuta Tomigashi had just turned around and found that the little bird Yurokuka was looking straight at her, and a flush flashed on her delicate little face.

"Liuhua, what's wrong?"

"Yuta...... No, nothing. She blushed and turned her head.

"Ha, it's still the same as always......" Yuta Tomigashi took the initiative to touch the tip of her nose, "Well, good night, Rokuka." ”

"Hmm...... Good night, Yuta!" Yukika Tori smiled shyly and sweetly.
