After the morning class, Cao An and his classmates gathered together and walked towards the computer.

Xiao Hai chattered all the way, his excitement evident in his words.

"Youyou is amazing. The voltage instability happened twice just now, right?" He said as he walked, putting his hand on Cao An's shoulder and asked, "This must be all turned on!"

Cao An's face was filled with uncontrollable joy. He held Na Ru with one hand and protected her from the students who were walking out of the teaching building to prevent her from being bumped into.

He didn't respond to Xiao Hai's chattering, but he was sure of it in his heart.

His baby sister must be amazing!

Thinking back to the scene when I first found her in that forest, I just thought she had encountered some god or monster.

That taking things out of thin air, that magical space.

Everything was brought by her!

Xia Youyou is a treasure, a treasure of this era!

Na Ru could feel his excitement, because the big hand holding hers was squeezing her so hard that it hurt slightly.

When the three of them arrived at the classroom on the second floor, Xia Youyou was still being dragged around and asked questions by students who were reluctant to leave.

She was not tired of it and even a little happy.

There's a feeling of being needed.

After she finished answering the question and straightened up, she noticed several people standing at the door.

Xia Youyou looked radiant today, and gave a confident smile to the few people.

Cao An's heart was beating like a drum, and his heart was full of gratitude towards her.

After a long time, I finally found my voice.

"Youyou, isn't get out of class over yet?"

The little girl helplessly gestured for him to look at the others, "Everyone is so excited right now that they don't want to leave get out of class."

She called for the end of get out of class right after the bell rang, and no one, including those in the other classroom, wanted to leave.

Including Yan Ke and several other teachers, they didn't even look at her, clicking with the mouse and typing on the keyboard awkwardly.

Xia Youyou walked to the door and took Naru's empty arm, "Sister Naru, go have lunch and bring me some back."

She didn't have much of an appetite right now, firstly because she was excited, and secondly because everyone was so eager to learn, she couldn't bear it.

Before Cao An could say anything, Xiao Hai, whose door was blocked by them, walked to the door of another classroom and said to them, "Bring me some food too. I'll go in and see how they operate."

He has been itching to do so for a long time!

Finally he got the chance to try it out!

Cao An turned his head to look at him, and only after seeing him enter the classroom did he look back at the little girl in front of him.

His big hand rubbed her head lovingly, which was resting on that shoulder. "What do you want to eat?"

"Anything is fine." Xia Youyou didn't care. She had no appetite, so it was good enough that she could eat it. There was no need to be picky.

"Brother, let me fry you an egg?" Cao An knew what she liked to eat, and she would eat it every time he made it.

Xia Youyou shook her head. "No need to bother. Just bring me a bowl of porridge."

Actually, they are all available in the space, but this is at school, so it is not very convenient.

Cao An said nothing more and led Na Ru away.

Xia Youyou watched the two of them leave, glanced at the classmates in the classroom who were staring at the computer intently, and turned to go to another room.

Xiao Hai only knew Yan Ke, so he could only bend over and support his knees to watch Yan Ke operate.

Xia Youyou waved when he looked up and pointed to her main computer on the podium.

Xiao Hai's eyes lit up and he immediately stood up and walked towards her.

The little girl smiled brightly and pursed her lips at him.

When Xiao Hai thought of this smile many years later, he still couldn't help but feel moved.

Under Xia Youyou's guidance, Xiao Hai moved a stool and sat down in front of the podium, suppressing the surging emotions of heartache and regaining his clarity of mind.

Xia Youyou didn't notice and started talking about computer operations.

Xiao Hai was unconsciously attracted by her soft voice, and began to move the mouse and operate the keyboard following her instructions.

It wasn't until Cao An and Na Ru came with lunch boxes and the aroma of food filled the entire classroom that everyone reacted.

Xia Youyou held the lunch box and said to Yan Ke, "Teacher Yan, please ask everyone to go eat. It's almost one o'clock!"

Yan Ke finally reacted and waved to everyone, "get out of class dismissed!"

There will be time later, your health is important now!

Everyone left reluctantly, and finally Xu Qiang shamelessly squeezed in next to a few people, "Xia Youyou, when is the next class?"

They all knew that it was a coincidence today. She just needed to test these computers, so she had an impromptu class today.

Xia Youyou swallowed the egg in her mouth and looked up at the people who turned around in anticipation after hearing these words.

In fact, she also felt sorry that she couldn't teach everyone right away.

So he said regretfully: "It's definitely not possible this year, but it will definitely be available when school starts next year!"

Whether it is a loudspeaker or a teaching book, it will take time.

She also has to write a set of teaching materials, which will be improved in due time, which will definitely be after the new year.

After everyone left dejectedly, the classroom returned to silence.

Cao An pulled Ru to sit down in the first row, and each of them took a computer and started trying to operate it.

Xia Youyou stood up with her lunch box, glanced at Xiao Hai who was eating while working on the podium, shook her head, and walked over to sit next to Na Ru.

Seeing her start to teach her, Na Ru said distressedly: "You eat first, we are not in a hurry."

"It's okay, we can talk while eating."

After eating a little, she closed the lid. Cao An, who was standing beside her, frowned as he watched.

However, Xia Youyou didn't notice and was concentrating on explaining the operation to them.

After the two of them became familiar with each other, they went to the classroom over there to take a look.

It must have been a strict instruction. All the computers in this classroom have been turned off, the room has been cleaned, and the tables and chairs have been neatly arranged.

Xia Youyou raised the corners of her lips, and she was looking forward to becoming a teacher more and more!

After locking the door, he turned to the other side, took a quick look at their operations, and then stood up and went to the podium.

"Brother Xiao Hai, go to the computer downstairs and operate it. I'll take control here and shut down the unused computers."

Xiao Hai stood up after hearing this, but did not leave.

He stood behind the little girl, watching her fingers flying. She clicked a few times on a piece of software, lighting up the two computers that Cao An was sitting on, and leaving one for him. He moved the mouse arrow to the shutdown button, and the sound of the machines in the classroom stopped. Only a row of three computers were still working, and the rest had automatically shut down.

"Wow, Youyou, you are so amazing!" Xiao Hai praised her generously and gave her a thumbs up.

Xia Youyou disagreed. This was just the beginning. After all, she was from the future, and these operations were just the basics.

She looked up and tilted her head towards Xiao Hai, motioning him to sit down.

Thin, white fingers moved on the keyboard, connecting Cao An's controls to two computers.

Cao An felt that the mouse stopped moving, then he looked at the little girl on the podium.

Na Ru was also confused, watching the operation interface return to the main interface.

The man next to her noticed and held her slender fingers on the keyboard with his big hands.

She turned to look at him, a silent question mark written on her face.
