Chapter 63 This guy is 10 years old?
Li Mengling was halfway through cooking when she sensed someone approaching from behind.
She turned around and saw Lingbo holding the test paper, which she handed over—
"I'm done. Can I leave now?" Lingbo asked expressionlessly.
"So fast?" Li Mengling was a little surprised. She put down the spatula, wiped her hands, and took the test paper. She intended to check it, but as soon as she held it, she realized something was wrong—
Oh no, I got too excited just now, why did I hand Lingbo a middle school exam paper?
Lingbo is only in third or fourth grade. If she got a test like this, she probably wouldn't be able to answer a single question, right? That's why she came over so quickly to say she "finished." Sigh, it's all my fault for being so careless.
However, before Li Mengling could even lament her mistake, her gaze swept over the solution process on the test paper, and she was completely dumbfounded—
The first question asks for the coordinates of the vertex of the quadratic function f(x) = 2x² - 8x + 5.
This was originally a classic problem about calculating vertex coordinates using the completing the square method, not considered difficult in middle school, but a child like Lingbo probably had never even heard of the concept of a "function." Look at what she wrote—
Differentiating f(x): f'(x) = d/dx (2x² - 8x + 5) = 4x - 8
4x - 8 = 0, solving for x gives x = 2
Substituting x = 2 into the original function to find y: f(2) = 2(2)² - 8(2) + 5 = -3
The vertex coordinates are (2, -3).
...?
Li Mengling's eyes widened, wondering if she was hallucinating. Wasn't this just direct differentiation? That's a method only high school students use, right?
For the second question, as shown in the figure, in circle O with radius r = 6 cm, AB = 6√3 cm. Find the area of the shaded region.
This type of problem can be cleverly solved by drawing a few auxiliary lines, and it is considered to be of medium difficulty within the scope of junior high school geometry.
Then Lingbo wrote—
x² + y² = r² = 36
…-π/2
S =∫ 2 *√(36 - 36 sin²θ)* 6 cosθ dθ
…-π/6
... (The middle part is the process of integration)
= 6π - 9√3 cm²
There were no auxiliary lines at all; instead, the result was calculated by brute force using definite integrals.
Li Mengling developed a deep sense of doubt about this world—
Is this guy 10 years old?
She flipped to the back of the test paper, and without exception, she wrote the answers to all the other questions using problem-solving approaches typically found in high school or even university.
"Teacher, if there are no other problems, I'll head home now."
While Li Mengling was still in a state of shock, Lingbo's voice brought her back to reality. Before she could react, Lingbo had already slipped to the door like an eel and left Li Mengling's house without looking back, almost as if she were fleeing.
"Ah... wait..."
Li Mengling instinctively wanted to call out to her, but the small figure had already disappeared outside the door.
She was left alone in the kitchen, staring blankly at the test paper, unable to utter a single word for a long time.
Having escaped Li Mengling's house, Lingbo walked down the street and let out a long sigh of relief.
Luckily, I managed to slip away while the other person was still in a daze. Otherwise, who knows what kind of trouble that overly friendly teacher would have gotten into next.
Being forcibly taken in as a disciple by someone I'd only known for less than an hour, and then forced to stay and do homework... What is this all about?
Lingbo took out her phone and checked the time; it was already past 6 o'clock. Although she had just gone through a battle and inexplicably had to do homework, it wasn't too late yet.
Lingbo looked around and saw a supermarket right across the street. "In that case," she thought, "I'll buy something before I go back."
Walking into the supermarket, the flow of people brought Lingbo back to her usual thoughts, and she began to consider what to cook for dinner.
You can buy some ham and soy sauce first, as we seem to be running out of soy sauce at home. We still have some vegetables at home, so there's no need to rush to buy more.
Lingbo, carrying a shopping basket, moved between the various shelves, carefully selecting items one by one, looking every bit like a "little housewife."
However, more and more people are looking at Lingbo.
After all, a silver-haired little girl dressed in cute Lolita fashion, carrying a shopping basket while grocery shopping in a supermarket, would definitely turn heads.
But then, a young woman who looked like a college student walked towards her with her phone in hand.
"Excuse me, are you the magical girl Ayanami-sama?" The young woman was looking at her with an excited expression.
--ah.
Lingbo suddenly realized a problem.
She looked down at her red and white Lolita dress, then looked up at the young woman.
—I was in magical girl form when I entered the supermarket, and I forgot to transform into Shen Zixin before coming in.
Faced with the young woman's question, Lingbo could only nod.
"Ahhh, it really is Ayanami-chan!" The young woman's voice suddenly became excited, attracting the attention of many other passersby.
It seemed that quite a few passersby recognized Lingbo, but were too shy to strike up a conversation. However, as the young woman started, the rest of the people went over to watch.
"It's the real Ayanami-chan!"
"Quick, take a picture!"
"She's a million times cuter in person than in the videos!"
Faced with the enthusiastic crowd, Lingbo unconsciously took a half step back.
"Lady Lingbo, are you here to shop too? Do you need any help? I can help you carry your shopping basket!"
"Is Ayanami-chan shopping for groceries for her family? She's so young yet so sensible!"
What should I do at this time?
Should we just run away? Although there are quite a few onlookers, it's only about seven or eight people, so it wouldn't be difficult to escape by force. But wouldn't doing that be a bit too rude?
Lingbo is really not good at dealing with situations where she is under the gaze of others.
Let's just be honest then.
"...Thank you everyone."
Lingbo closed her eyes, bowed slightly, and greeted everyone.
"I have something to do today, so I won't be able to chat with you all for the time being."
After saying that, she slowly left through the gaps in the crowd, leaving behind only the people behind her whispering among themselves.
"Lingbo is indeed very aloof."
"That little child must have been frightened by so many adults watching!"
Lingbo walked towards the checkout area. Right now, all she wanted was to leave the supermarket as soon as possible and turn back into Shen Zixin.
Of course, some people might be quite comfortable with being in the spotlight. But Lingbo clearly isn't one of them. While she might be able to barely accept being watched like this as a male adult, being the center of attention as a young girl obviously makes her very conflicted.
She thought back to her decision that morning to refuse the Civil Defense Bureau's suggestion to open a personal account, and felt even more strongly that she had made the right decision. She just wanted to quietly protect the everyday life she cherished, and as for the glamorous identity of "Magical Girl Rei," it was best if it only existed in people's imaginations.
