The Lin family's little boy returns to being eight years old, taking his family to new heights.

[Ding. Congratulations, host, you have completed all your exercise and study tasks yesterday. The following rewards have been issued. Please check them.]

A pair of daily disposable contact lenses: relieves eye strain, prevents myopia, and protects your eyes 24 hours a day.

One drop of Power Spinach Juice: Boosts strength, making lifting effortless for 3 hours.

Lin Xi rubbed her eyes, still half asleep, after staying up too late the night before.

Hearing about the new reward, he suddenly snapped out of it.

"Host, we recommend that you wear contact lenses now. They will automatically dissolve within 24 hours after wearing them."

It doesn't want its host to become nearsighted at a young age.

I had overused my eyes yesterday, and this system was a lifesaver.

"Wow, it's cool and so refreshing!"

After wearing them, there was no foreign body sensation, and my eyes, which had been dry from staying up all night, immediately stopped feeling dry.

If Lin Xi looked in the mirror, she would find that her eyes were watery, bright, and lively.

After starting school, even Su Xin secretly wondered how his deskmate seemed to be evolving every day, and how he had become even more handsome today.

The morning sun has just warmed the earth, and the evening twilight has already quietly descended; a day seems to pass in the blink of an eye.

Lin Xi's study task for today was to review fifth-grade math. After finishing the first semester, she said goodbye to her grandmother and went to Lin Jing's house.

"What? You've finished learning all of fourth grade? You learned a year's worth in three days?"

Lin Xi's eardrums were almost ruptured by the shock.

He scratched his ear and explained that he would be studying at her house for the next few days until he finished reading the fifth-grade textbook.

Lin Jing could understand that Lin Xi could finish a math exam in a day because she was talented and had strong logical thinking, but memorizing thousands of words and hundreds of ancient poems in a day was just too exaggerated.

Unable to understand, Lin Jing randomly tested him on several ancient poems and dozens of words, all of which were long and difficult to understand. However, he made no mistakes and answered them without hesitation.

"Xiao Xi, you must be a child prodigy! You have a photographic memory!"

Lin Xi chuckled and said, "Didn't I say a few days ago that having a fever opened up my Ren and Du meridians?"

Lin Jing wondered why such a good thing hadn't happened to her, then resignedly took out her math book from her bag and handed it to Lin Xi.

Then they were utterly crushed!

She just flipped through the pages and thought she could figure it out? Without even touching a pen?

The difference between people is just so huge! Compared to them, she looks as stupid as a pig!

More than half an hour later, the sound of turning pages stopped.

"Thank you, sister. I've finished reading it. I'm going home now. I'll come see you again tomorrow."

Lin Jing was currently struggling with a math problem, clutching her messy hair. Seeing Lin Xi about to leave, she quickly called out, "Xiao Xi, can you help me with this problem?"

After reading the question, Lin Xi didn't even think about it. She picked up a pen and paper and started writing. She finished in less than a minute.

Lin Jing read it once, first suddenly understood, then frowned, because there was one step she couldn't figure out, so she humbly asked her younger sister for help.

After Lin Xi patiently explained it to her, the girl relaxed her furrowed brows. "Oh, I see."

"Xiaoxi, thank you. You explained it even better than our teacher. I understood it right away."

"Hi, I just explained my problem-solving approach. Do you have any other questions?"

Lin Jing immediately took out the test paper that the teacher had just graded during the day and asked Lin Xi to explain the questions she had gotten wrong.

After explaining everything, it was already quite dark. Lin Jing felt a little embarrassed, so she offered to take Lin Xi home.

Lin Xi refused the offer to take her home, but she was worried about letting the ten-year-old girl go home alone, so in the end, her grandmother would have to take her. Instead of going back and forth, she figured it was better to walk herself, especially since it wasn't far.

Although she was a little afraid of the dark, it was good that Xiao Yi was there to talk and chat with her.

As soon as I stepped outside, the system voice sounded.

[Ding. The host answered Lin Jing's questions, boosting Lin Jing's confidence in learning mathematics. 10 Heart Coins awarded.]

I now have 65 Love Coins, and unlocking the system shop is just around the corner.

When she got home, Lin Guiying was already waiting for her at the gate. She breathed a sigh of relief when she saw her granddaughter.

"Grandma, we were discussing some problems, and we have to go to Sister Lin Jing's house to study tomorrow." Lin Xi could tell at a glance that her grandmother was worried about her, so she explained in time.

Lin Guiying assumed that Lin Jing was explaining the problems to Lin Xi. She thought it was a good thing that the child was eager to learn, and she couldn't stop her. After giving a few instructions, she went back to her room.

Lin Xi returned to her bedroom and began writing the novel she hadn't finished yesterday.

As a result, Grandma caught him again in the middle of the night.

Lin Xi didn't want to either; she got so engrossed in writing that she couldn't stop and completely forgot to check the time.

Without a cell phone or alarm clock, it's already midnight again before I know it.

After being scolded by her grandmother, Lin Xi quickly took off her shoes and went to bed. Her whole family was afraid of Lin Guiying's sharp tongue.

......

The warm winter sun shone on the girl's long eyelashes. Because she wore contact lenses yesterday, her eyes were not dry at all today, and she had no aftereffects of staying up late.

Lin Xi put on the glasses that the system had just rewarded her with that morning and went to school with a great sense of peace.

Su Xin, the chubby little boy, leaned over and said in a cheeky tone, "Lin Xi, I've finished my essay too. This time, Dad didn't scold me; he even praised me for writing well."

Actually, Su Youcheng really wanted to say that he was far inferior to Lin Xi, but seeing that his son had finally developed an interest in learning, he didn't want to discourage him.

"Congratulations, my deskmate! Keep up the good work! The monthly exam is coming up soon, and your dad will be even happier if your grades improve."

"Don't worry, I've started to put in a lot of effort these past few days. You have to work hard too, hahaha, don't let me surpass you."

Lin Xi looked at the arrogant child, wondering if he would still be so confident after the exam.

Ever since she was exposed, Teacher Yang has called her name in class every day.

Teacher Su would glance at her from time to time while lecturing.

"Now, I'll give you an interesting question about this topic. Try to solve it, and it's okay if you can't."

This is an Olympiad math problem that Su Youcheng saw in a math journal. It involves today's knowledge points and can be used to broaden students' thinking.

After writing quickly on the blackboard, the students enthusiastically picked up their pens to calculate. After a while, they all scratched their heads and began to whisper among themselves.

He had already imagined this scenario, and habitually glanced at Lin Xi.

Unlike the other students who looked puzzled, she calmly scribbled on the paper, appearing quite interested.

Could it be that she would?

As Su Youcheng stepped down from the podium, the students' whispers abruptly ceased, and they pretended to be deep in thought.

When I reached Lin Xi's spot, she had just finished solving the problem.

The solution process above is smooth and even simpler than his solution method, except that there is one knowledge point that can only be learned in the 5th grade.
