Honkai: It’s broken, I have become the Herrscher of Corrosion?

The first test was a cultural exam. After looking at the questions, Enosia understood why Kiana failed.

[How to effectively convert Houkai energy into chemical energy, electrical energy and other energy sources useful for human production and life has always been a research topic of Tianming. It is known that a power station has a transmission voltage of U=6000V and a transmission power of P=500kw. At this time, the watt-hour meters installed at the starting point and the end point of the transmission line show that the difference between the day and night is 4800kw/h.

(1) Calculate the transmission efficiency and resistance

(2) It is known that the higher the Honkai energy, the higher the efficiency of electrical energy conversion. However, when the Honkai energy exceeds 10HW, the staff will be in danger of becoming dead. How to increase the transport efficiency and reduce the electrical loss power while ensuring the safety of the staff? Please use calculations and words to write down your opinions...]

As soon as Enosia glanced at the questions, she felt a sense of fatigue rising in her heart. Without any hesitation, she immediately used the power of the Herrscher to start searching for questions.

“P损=4800/24=200kw，所以输出效率=（P-P损）/P=(500-200)/500=60%

Because P loss = I2P line, P = IU

所以R线=P损/（P/U)2=(200X1000)/(500x1000/600)2=28.8w

"Well, the process doesn't seem too complicated. As for why we have to do this... never mind, just copy it."

"The second question is an open question, there is no standard answer... If there is one, then let the Herrscher of Thunder transmit electricity. This will ensure efficiency and there is no need to worry about infection. It kills two birds with one stone."

The questions that followed became increasingly difficult, involving both integration and differentiation, and in the end even quantum mechanics came up. Enosia simply stopped thinking.

With her indomitable courage and persistent belief, she created one person, one pen, one lamp, one hour, and one miracle.

Yes, the exam was originally scheduled to last 150 minutes, but Enosiya only took 60 minutes to fill out the test paper and was the first one in the school to hand in the paper.

Unlike at Chiba Academy, the departure of Enosia did not attract much attention from others, because most people were either racking their brains or writing furiously, and were so focused that they didn't care about what others were doing.

The reason why it was the majority was that when Enosia handed in her paper, Kiana, who was sitting in the back row by the window, was sleeping soundly on the table. She even seemed to see the ZZZs floating out.

At noon, the cafeteria was filled with voices discussing the answers.

"For the sixth question, I can't figure it out. It's really giving me a headache."

"Oh, I don't care. Anyway, I am Luo. Otherwise, I will have to wait till the end of time..."

Kiana was obviously out of tune with the others. She waited until almost everyone else had left before she yawned, rubbed her eyes, walked out of the classroom, stretched, and then rushed into the cafeteria like a 100-meter racer.

The cafeteria was already crowded at this moment, but fortunately Mei and Bronya had prepared a four-person dining table in advance, and Mei was very considerate and prepared some of her favorite dishes for her in advance.

"Wow, there are so many foods. The food at Saint Freya is really good."

Kiana sat down on the chair, raised her hand, grabbed a chicken leg and put it into her mouth.

"Stupid Kiana, what's the fuss about? This is the big cafeteria where you eat with other Valkyries below rank B. If you pass the B-rank Valkyrie test, you can go to the special cafeteria that only B-rank and higher Valkyries can enter... Wait, judging from your expression, you didn't listen to me at all this morning, did you?"

Seeing Kiana's full of energy, Mei saw something was going on:

"Kiana, how did your morning exam go?"

Kiana immediately showed a disdainful look:

"Hmph, I don't know what's the point of taking these questions that make people sleepy. Can I compete with Honkai Beasts on the battlefield? It can make me fight... No, it's about who defeats more enemies, that's more valuable."

"Stupid Kiana, do you know that if your test scores are very bad, you can't enter the elite class."

"Bronya, I remember that the morning exam accounts for 40% and the afternoon mock battle accounts for 60%. As long as I get a perfect score in the afternoon, it won't be difficult to get into the elite class."

"Then I'll look forward to Kiana's performance."

A familiar voice came, and Kiana turned around immediately:

"Enosia, you are here too!"

"I wonder if I could join you?"

The three of them said they had no objection, and Enosia sat down between Kiana and Bronya.

"Enosia...Are you the Enosia who always tops the grade at Chiba Academy?"

"Ah, I didn't expect Mei-senpai to recognize me. I know what you want to ask. When the Honkai disaster occurred, my family was not in Changkong City, so we happened to escape the disaster. However... Xilin and Ivan have their own ideas. At least they have no intention of becoming Valkyries at the moment..."

Bronya looked at the empty space in front of Enosia with a puzzled expression.

"Aino...Xia, you eat..."

Before he could finish his words, Kiana immediately interrupted:

"Aino, you must have handed in your paper early again. You came to the cafeteria early and have already finished eating, right? When you were in Qianyu Academy, you were the first to hand in your paper during every exam..."

"Yeah, and every time I see you who never goes to take the exam... Oh, by the way, Mei, and Bronya, don't be so reserved. Meeting is fate. Just like Kiana, just call me Aino."

Bronya listened to Kiana and Enosia chatting animatedly, and became more curious about her. Finally, she couldn't help but ask:

"...Aino, so how long did your morning exam take?"

Enosia blinked:

"Um... maybe... a little over an hour?"

"what!"

Mei and Bronya exclaimed at the same time.

"So...Aino, do you play games?"

Before Enosia could question Bronya's jumping thoughts, Kiana spoke for her:

"Bronya, what does the exam have to do with playing games?"

Bronya raised the corners of her mouth slightly:

"Stupid Kiana, playing games is like taking exams, both involve using your brain. Someone as simple-minded and strong-limbed as you won't understand."

Enosia looked at the cafeteria, which was obviously becoming less crowded, and slowly stood up:

"It's almost time. I won't delay your meal. Bronya, we can talk about playing games next time we meet. After all, we are all alumni and there will be plenty of opportunities to meet in the future."

Walking out of the cafeteria, Enosiya looked at the building in the distance, where the assessment would be held in the afternoon.

"Oh, using cheats without being discovered is really a technical job."
