Chapter 58

Niu Kaihuai realized something was wrong almost as soon as the first half of Shen Yue\'s sentence left her mouth.

He knew that if she was really a sweet younger sister, would he need to come over and serve as her homeroom teacher? Her feelings must be waiting for him here!

The second oldest was a chuunibyou. The third oldest was an introvert. The fourth oldest was a delicate flower. The fifth oldest was a psycho.

The sixth oldest...currently seemed to be the sixth oldest.

She stabbed him when he wasn\'t paying attention.

"Shen Yue, sleeping is not allowed during class time. If you violate the classroom rules, I may have to take certain measures," said Niu Kaihuai.

After thinking for a bit, Shen Yue earnestly asked, "Then what can I do to sleep during class?"

She really didn\'t want to experience the pain of being woken up halfway through her sleep again. She just wanted to sleep soundly.

But Niu Kaihuai was unmoved. "You can\'t sleep no matter what. I\'ll tell you the specific classroom rules later. For now, go sit in that empty seat over there and listen to class with everyone else."

Shen Yue looked at the seat left for her and felt a little sad.

It was right next to the window.

There weren\'t any curtains.

That meant if sunlight streamed in, it would be very glaring.

She would check when she got home that night to see if she had an eye mask at home that she could bring. She seemed to remember having one before.

She would also secretly buy some earplugs.

Just as Shen Yue was about to go sit down, someone suddenly raised their hand and said, "Teacher, I think there may be functional disturbances in Shen Yue\'s brain. It would be best to send her to the hospital for an examination right now rather than have her attend class here."

This was said very aggressively. If an ordinary person had said it, there was a high probability it was meant to mock Shen Yue\'s poor brain and suggest she go to the hospital for an examination.

But this wasn\'t said by an ordinary person, rather by Mi Qian. He was only 13 years old, yet had defeated many opponents older than him. He took first place with absolute advantage in the National Science Competition\'s youth group.

Everything he said had a reason behind it.

After all, Mi Qian\'s motto was to not speak a sentence of nonsense or do a meaningless thing.

Unsurprisingly, Niu Kaihuai didn\'t criticize Mi Qian at all. Instead, he looked over with a great attitude and asked, "Why do you say that?"

Mi Qian pushed up his glasses. His entire body suddenly emitted a professional aura. In a steady tone, he began explaining, "People want to sleep because the pineal gland in the hypothalamus secretes melatonin, which has a sedative effect that can reduce bodily activity and increase fatigue.

Serotonin is a neurotransmitter that can cause central nervous excitement and pleasure. It is secreted in alternation with melatonin and generally maintains a person\'s alertness and excitation during the day. Therefore, if one wants to sleep during the day, especially during a joyful time like class, it is most likely caused by a sleep disorder due to an abnormality in the secretion of these two neurotransmitters, or it could be due to insufficient blood supply to the brain."

After finishing, Mi Qian pushed up his glasses again. "I suggest immediately sending her to the hospital to check if any abnormalities in bodily indicators have appeared recently."

Niu Kaihuai: ...Isn\'t there a possibility she\'s just lazy?

Niu Kaihuai understood that the students in this class were rather unique. In their mindset, even emotions like laziness might not exist, so it was difficult to judge and analyze some matters from those perspectives.

Perhaps Shen Yue was a great opportunity for them to understand ordinary people.

Niu Kaihuai instantly understood why an outlier was placed among these geniuses - it was to improve these geniuses\' personalities!

However, using his own younger sister as a tool for improvement was quite ruthless.

Before Niu Kaihuai could finish feeling conflicted, another student raised their hand. Without even waiting for Niu Kaihuai to call on them, they started speaking on their own, "Mi Qian, I disagree with what you said. You only considered the new student\'s fondness for sleep from the perspective of brain function, but if looking at it from the angle of mental illness, this is clearly a symptom of depression.

In addition to lack of motivation as the main manifestation of depression-induced somnolence, there is also lack of desire to do anything, increased sleep, and even diminished volition and so on. You can tell from observing the new student\'s eyes that it\'s not as simple as you make it sound."

Right after finishing speaking, without even catching their breath, another person on the other side stood up and started rebutting, "What both of you say may have some merit, but it only applies to general cases. If it\'s neither ordinary metabolic abnormalities and temporary disorders, then it is extremely likely to be Kleine-Levin syndrome, commonly known as KLS.

Haven\'t you noticed the new student\'s limp posture, dispiritedness, and even seeming on the verge of falling asleep? Doesn\'t it seem like that rare neurological disorder?

In some cases, somnogenic particles make it difficult for people to wake up from sleep. Somnogen is composed of amino acids, like a protein, and likely causes people with this disease to be bedridden for years.

Prolonged sleep leads to shallower brain folds. To put it simply, the brain captures information during the day and completes establishing and filtering the index during the night. Excessive sleep actually disrupts this normal mechanism and can lead to behavior similar to amnesia.

I can do an experiment right now.

New student, do you know what Mi Qian\'s name is?"

Shen Yue: ?

This person seems to have something wrong with their brain. She doesn\'t want to answer.

Shen Yue not answering only made Zhuo Wenxi more certain of his guess. "You see, I just said it would lead to memory loss. The new student doesn\'t even remember the name I just said. Teacher Niu, I suggest having the new student\'s parents take her to the Number One People\'s Hospital for an examination as soon as possible."

Niu Kaihuai: ...

Just now, he was definitely certain that Shen Yue wanted to sleep in class purely because she was lazy. But now, he couldn\'t be certain.

He wasn\'t particularly proficient in biology. Some children present were even more professional than him.

If three students all felt something was wrong with Shen Yue, then Shen Yue...really might have an issue.

Now that this kid Shen Yue was handed over to him, he had to take responsibility for her. But before taking responsibility, he first had to know what exactly he should be responsible for!

"What you\'ve all said is possible, but I saw an interesting theory yesterday called cellular rejection. The human body chooses a comfortable environment for itself. Perhaps for the new student, our cells are too comfortable, so she wants to sleep."

"Then you mean it\'s not a simple neurological illness, but something wrong with her cells? Cancer?"

As Niu Kaihuai listened to the discussion, he sank into thought for a bit before decisively taking out his phone and calling Shen Yichen.

"Hello, big brother Shen Yichen. There\'s a possibility your sister has contracted an incurable illness. Why don\'t you bring her to the hospital for an examination right now?"
