Although she never listened well in class, she did know the vague structure diagram, and the cranial nerves were crooked, and she could count them one by one, as if there was a microscope in front of her.

Sensory afferents reach the nerve center and connect to the gray matter area of the brain to control the person's thinking activity. Well, that's all she remembers.

Cheng Jiali vaguely remembered that the human brain model mentioned in the book was probably like this. The most inconspicuous area in the lower right corner seems to have been marked by a red pen, and the moving red dot looks like she is emotional.

"The system intelligently detects the area that the owner wants to delete, and marks it with far infrared rays, and asks the owner to check whether it is correct."

All the places where the red dots walked were described in regular words, so Cheng Jiali didn't have a hard time looking at it, she nodded emphatically, indicating that it was completely correct.

"The owner has selected the deletion area, and the deletion is successful." She was thrilled by the green tick, and although she sometimes used a computer, it was fresh and fun to use hands-free control.

Chen Liming was excited, his dull eyes regained their brilliance, and he looked at Cheng Jiali, who was very close to him, and was stunned for a while, and his eyes became dazed and complicated.

Not only him, but everyone seemed to come back to their senses, Cheng Jiali glanced at a few strange glances, and turned to a hint of an unfathomable smile on the corner of her mouth.

Chen Liming saw her standing outside the door and beckoned her into the classroom, and didn't mention the running thing again, as if he had really forgotten it. Seeing that the classroom was empty, he thought it was a collective lateness, and criticized a few words sharply, until the class leader Zhao Ran told him that these classmates were running in the playground, and his expression changed and changed.

Zhao Ran didn't say anything more when he saw his strange appearance, and called all the people running on the playground back to the classroom according to his instructions.

Yesterday, the news that most of the students in the class went home early seemed to have been blocked, and the students had a discussion in private, but who was not happy about the matter of being exempted from punishment, so they all tacitly cooperated and no one took the initiative to mention the matter.

Because she lost 800 ml of blood before, Cheng Jiali still felt a little dizzy, so she didn't listen to much content in the morning.

However, Xu Jiaying saw her sick appearance and asked her what was wrong with concern. She just smiled and said that it was okay and barely survived.

She felt very sleepy, and she dozed off many times in each class, but fortunately, she tried her best to listen carefully when the teacher turned around so that she was not noticed by the teacher.

"Why don't I take you to the infirmary?" Xu Jiaying was not very relieved, and twisted her eyebrows and reached out to probe Cheng Jiali's forehead.

"No fever." She muttered, her face solemn as if she was thinking about something.

"In the replenishment of lost blood, this intelligent replenishment is 1000 ml." Cheng Jiali's mouth was wide open, with a frightened expression, she scared Xu Jiaying, who was looking at her, like this.

"Are you alright?" Cheng Jiali smiled, secretly stuck out her tongue, but her head no longer felt wooden, and her consciousness was very clear and her thoughts were very concentrated at this moment.

My mind is full of one question: can the blood that was sucked back really be replaced?

"The blood is transported through the atrial conversion procedure, and the procedure is executed." Atrium? Cheng Jiali was busy touching her chest, her heart was beating hard!

There was no more powerlessness, the tiredness was gone, she felt her whole body full of energy, and every cell in her body was active, so she couldn't help but jump in place a few times.

"You can run a few laps and I guess you'll find it downstairs." Fang Yao looked at her strange behavior and smiled.

"I guess it's not uncomfortable to see you jumping around." Xu Jiaying also laughed, her eyes curved like crescents were bright and beautiful.

"I feel refreshed." Cheng Jiali raised her clenched fists high, looking like a superman, which made everyone in the classroom laugh.

"I'm still an armored warrior." A boy joked.

Cheng Jiali, who had recovered her mental strength, felt as if she had been beaten with chicken blood, and after lunch, she took out a few chemical papers and made them.

Speaking of which, she was quite ashamed, she only did a few questions not long after she bought the volume, and she put it in her schoolbag and carried it every day, which was a comfort to her heart.

There were only two people in the huge classroom, she and Zhao Ran, and when she withdrew her gaze from the sea of questions, her gaze couldn't help but fall on the first row.

It seems that no matter when, when she sees Zhao Ran, she is reading a book seriously. It stands to reason that such a person should be a nerd, but Zhao Ran is a fan of books, but he is not stupid. He participates in almost all school activities, and he is always active on the basketball and football court.

He has strong organizational skills, and once organized a basketball game on his own, and the process went smoothly and accumulated a lot of contacts.

In terms of sports and study, he doesn't seem to be unprofessional, and he almost sits in the top three in the class in every exam, and the first place in the class, which also allows him to win some honors for the third class with a bad reputation.

The school considered transferring him to the key class, but Zhao Ran declined the kindness of the grade director, and the reason for the refusal was because since he was the head of the third class, he naturally had to take due responsibility.

The teachers had nothing to say, and they valued this high-spirited teenager more.

He is very good, and there are naturally many girls who like him, some have boldly written love letters to him, and some have secretly crushed and paid attention to him, but his focus seems to be always on learning.

Cheng Jiali stared at the almost blank test paper in a daze, she didn't know many of the questions on it, her foundation was too poor.

She thought about the problem for a long time and had no idea, so she had to ask Xueba for help.

Afraid of disturbing Zhao Ran, she kept the sound of moving the stool as low as possible, and walked gently to Zhao Ran with the test paper.

"Squad leader." Cheng Jiali screamed weakly, she and Zhao Ran had very little intersection, and she didn't usually teach him much, so she was a little nervous.

Zhao Ran withdrew his gaze and turned to her, and glanced at the scroll in her hand lightly, "What's wrong?" His voice was deep, without impatience.

"Can you give me a few questions?" Zhao Ran glanced at her very strangely, Cheng Jiali just smiled, she knew what he was thinking in her heart, a person like her, who usually doesn't like to study, would also ask questions?

However, Zhao Ran just glanced at her, and patiently explained all the questions to her.

Zhao Ran spoke very slowly, and waited for Cheng Jiali to thoroughly digest it before moving on to the next question. This process took nearly an hour, and Cheng Jiali felt very embarrassed, but she was really grateful.

His solution is very simple and logical, even a person like her, who is super slow to react, can understand it very easily.

"I remember that you scored 79 points in the last chemistry test, which is quite good, and if you continue to work hard, your score will definitely improve again." Cheng Jiali accepted this praise with trepidation.

"You can ask me any questions next time." His gaze was clear, and there was an imperceptible smile in the corner of his eye.
