The National Day holiday lasted for seven days. Qin Ke had originally thought about going with Ning Qingyun to visit her grandfather. However, Ning Qingyun and her grandma Chu Mimei stayed in the nursing home for six days at a time, and the journey was too far. Qin Ke was embarrassed.

I would trouble Grandpa Ning to arrange a vehicle to take him back to Yuanzhou in advance, so I had to give it up for now and plan to take a weekend at the end of October to visit Grandpa Ning with Ning Qingyun.

So his plan was reworked.

He planned to stay in his hometown for five days to spend time with his family, and then return to the city on the sixth day to clean up the lush green house. After all, it was his and Ning Qingyun's "home".

Then on the seventh day, I went to visit Professor Shi Cunyuan and Lin Haibo.

He had already found out clearly that his grandfather was going to meet these two old friends on October 6th, so he could stagger his arrival so that he could take his grandfather's car back to the city.

As for the five days in his hometown, Qin Ke plans to attend class reunions in junior high school and elementary school, and play a few hearty basketball games with old friends from the past, such as Wei Hai and others.

In addition to this time, Qin Ke plans to finish writing five papers on new operating systems. If he still has free time, he will slowly enter more than 70,000 lines of code from Weiguang v0.1 version into a real-world laptop.

inside.

The plan for October 1st went smoothly. Qin Ke took the bus back to Qingping Town in the morning and attended the junior high school reunion in the afternoon.

His junior high school classmates were already fawning over him. Although Qin Ke was originally the top academic in junior high school, no one expected that he would soar to the sky after high school and become a nationally famous academic god. He was directly recommended to Qingmu University.

.

Those female classmates who had already sent him love letters were even more enthusiastic. Fortunately, Qin Ke had rich experience and could show off his tricks.

He didn't want to make his lovely little cabbage sad because of some ambiguous misunderstanding with his former female classmate.

Faced with a slightly different junior high school reunion, Qin Ke even hesitated later. Otherwise, he would not attend the elementary school reunion tomorrow? But there were some close friends in elementary school whom he had not seen for a long time...

But an unplanned accident helped him make his decision.

In the evening of the same day, after the class reunion, Qin Ke went to play basketball with Wei Hai and other friends from Qingping High School. He was getting excited about playing basketball. Unexpectedly, it suddenly started raining heavily in the middle of the game. The group had to interrupt the game and take shelter under the eaves of a nearby roof.

As a result, after waiting for half an hour, the rain showed no signs of abating. Instead, it became heavier and heavier.

It is difficult to get a taxi in this small place. Qin Ke was just thinking about whether he should just run home and take a hot shower when he saw Qin Xiaoke running to pick him up with an umbrella.

It was windy and rainy, and the umbrella was delivered, but the little girl herself was mostly soaked, which made Qin Ke dumbfounded and had to take her home quickly.

Qin Xiaoke developed a fever in the middle of the night, reaching nearly 40 degrees Celsius. Qin Ke and his father rushed her to the hospital in the small town. They worked all night and the results showed that there was nothing serious. It was just a cold caused by a cold.

Qin Xiaoke, a little otaku, was not in good health to begin with. After catching cold in the wind and rain, her immunity was reduced, so she caught a severe cold, and her high fever subsided and turned into a low fever, again and again.

Well, Qin Ke doesn't have to attend the elementary school class reunion, so he can only stay by his sister's bedside to take care of her.

It wasn't until the evening of October 4th that Qin Xiaoke's recurring low-grade fever finally subsided.

Qin Ke put away the thermometer gun, breathed a sigh of relief, and asked: "Little sister, do you want to eat something? I cooked your favorite egg drop beef porridge for you."

The blush from the fever still remained on Qin Xiaoke's face. She looked at her brother's unconcealable tiredness, her eyes were red and she said with guilt:

"Brother, I'm sorry, I always have to trouble you to take care of me..."

"I'm just a sister like you, what stupid things are you saying?" Qin Ke smiled and stretched out his hand to rub the little girl's hair:

"But you're smart, you didn't get sick until I was at home. If you expect your parents to take care of you, just cry. Mom can do anything like giving you medicine with coke, and dad is free.

People who don’t live here will go crazy if they stay here to take care of you for a long time.”

Qin Xiaoke couldn't help but smile, stretched out his hand to hold Qin Ke's hand, and asked: "Brother, have you been delayed in accompanying Sister Ning during this holiday?"

"I don't believe you didn't contact her even though you knew it. Your sister Ning is still with her grandfather. She won't be returning to Yuanzhou until tomorrow. What's the delay?"

"It won't delay you and Sister Ning, just be intimate with each other, hehe!"

"Hey, you're such a fool! You're a little girl who's only in the second grade of junior high school. Don't talk about me and me all day long!" Qin Ke flicked her forehead.

"Oh...I miss Sister Ning so much...Brother, when will you bring Sister Ning back to play? My parents have been talking about wanting to see her, especially my mother. If I hadn't stopped her, she would have sneaked away to your school.

Let’s go see Sister Ning.”

Qin Ke thought of his mother's character. She had always been obsessed with love stories and had asked him to find a girlfriend since he was a child. Now that he finally had a girlfriend, it was strange that she wasn't curious and unhappy.

In fact, his mother has been asking him about Ning Qingyun in front of him in the past few days. Qin Ke directly sent his mother a bunch of photos and short videos of the two of them traveling on his mobile phone, and then blocked her.

curiosity.

"It turns out that you played a key role. I won't tease you next time. Your sister Ning is so tender-skinned that she probably won't have the courage to come to our house until she goes to college. Well, next time you do well in the exam, I will

I’ll take you to the city when I come back so you can see your sister Ning.”

Qin Xiaoke lowered his head and suddenly said: "Sister Ning is really the best girl in the world. Brother, you have to be nice to her and don't bully her."

"You are a big kid, so you don't need to give me orders for such things. By the way, you have to eat something first. Wait, I will serve you some porridge."

Qin Ke quickly brought back a bowl of porridge: "Can you eat it yourself or do you want me to feed it?"

Qin Xiaoke said nothing and looked at Qin Ke pitifully like a little puppy.

Oh, that's a good look. Pretending to be pitiful is an improvement. Qin Ke smiled and silently wrote it down so that he could use it on Ning Qingyun at any time in the future.

Qin Ke helped his little sister sit on the bedside, filled a spoonful of porridge, tested the temperature, and handed it over.

"Open your mouth."

Qin Xiaoke happily opened his mouth to suck it. After eating the porridge, the little girl covered half of her face with a quilt, looked at Qin Ke without blinking, and suddenly said softly: "I miss you so much..."

"Huh? What do you miss?"

Qin Xiaoke concealed the emotion in his eyes and showed a cheerful smile: "It's nothing. Brother, you don't need to worry about me. If you have anything to do, just do it. I'll just lie down like this."

"Okay, I'm going to continue writing my paper. Do you want me to get you some comics?"

"No, I'll just continue reading the second grade story you sent me. I haven't finished it yet."

"How do the students in the class respond to this set of mathematics teaching aids?"

"Very good. By the way, brother, I haven't told you yet. In the final exam of our class last semester, the average math score increased by 10 points, ranking first in the whole class! Everyone admires you very much!" Qin Xiaoke

She seemed to be reminded of the scene at school, and couldn't help but cross her waist proudly. If she had a tail, it would probably be raised very high by now.

Qin Ke is also a little proud. It is indeed a pleasure for the fruits of his labor to be recognized by others and play a role.

"Tell your sister Ning these words and make her happy too."

"I know, hehe. By the way, bro, have you made any operating system recently? Sister Ning asked me to discuss making a beautiful UI, and I even drew some icons for her."

"Yes, it is an operating system similar to macOS on Fruit Notebook. If you have time, please cooperate with your sister Ning. When your UI is designed, I will add it to the operating system to use as the interface."

"Brother, you are so awesome! Sometimes I wonder if you are my biological brother, and why our IQs are so different..." Qin Xiaoke was a little frustrated at the end.

"I should have a genetic mutation. You can see that my parents' IQs are about the same as yours. Okay, I'm going to write a paper."

Qin Ke opened his laptop and continued to type the paper while talking.

In fact, after Qin Xiaoke fell asleep after taking medicine in the past few days, Qin Ke sat on the small desk next to her, typing the paper.

Because he did not attend the elementary school reunion and declined some boring activities, his thesis progressed faster than planned.

For Qin Ke, writing papers related to operating systems does not require much brainpower.

With his current operating system technical attainments, coupled with his systematic "New Modular Operating System Design Ideas", it was easy and enjoyable to finish just five papers.

The themes of these five papers were determined by Qin Ke after adding his own thinking and practical experience. They are:

"On the exploration and conception of a modular architecture operating system"

"An exploration of the shortcomings of current human-computer interaction methods in operating systems and the possibility of remedying them through artificial intelligence"

"A Preliminary Study on the Convenience of Artificial Intelligence Learning Algorithms and Operating Systems"

"Thoughts on developing a new operating system with artificial intelligence as the core and modular thinking"

"Case study of operating system hardware management module with artificial intelligence as the core and written with KEY module rules"

The word count of each paper is between 3,000 and 5,000 words. It does not involve specific codes, but it has extremely detailed design ideas and algorithm deductions.

Qin Ke had already drafted the five papers in his mind, and all he had to do during the vacation was to type out the words while thinking about them.

With Qin Ke's hand speed, he can type 80-100 words in one minute at the fastest. However, writing a paper takes a lot of thinking time, and it takes Qin Ke about five hours to finish coding.

Today is October 5th, and now he is writing the fifth article.

While typing on the keyboard, Qin Ke sighed in his heart. Sure enough, it was more comfortable to write a paper in Chinese, and it didn't burn as much brain cells as writing an English paper!

Just like "interest", you only need to spell two sounds, and there is no need to spell "for lack of thinking"!

It seems that it is imperative to develop a domestic operating system. At least all operations in it can be controlled using Chinese text and voice!

Here Qin Ke is writing a paper quickly, and Qin Xiaoke next to him is looking at Qin Ke's photocopied storybook for the second grade of junior high school teaching aid, and looking at Qin Ke from time to time.
Chapter completed!
