Legacy

A total of 64 of the most outstanding new students came to participate in Zhen Hua High School's youth talent training camp. In the end, only two chose to participate in the Informatics Olympiad-related studies this summer. One male student, one female student. The male student's name was Su Yun Xuan, and the female student's name was Han Jiang Yue.

Teacher Xu led them to the school's computer lab to experience the programming curriculum, and naturally observed the talents of the two. Su Yun Xuan, who had been exposed to programming since middle school, had outstanding computer talent. Han Jiang Yue, who had never been exposed to programming but chose Teacher Xu and Liu Qing Yun out of interest, had very good computer talent. Such talent, although not dazzling, was still extremely outstanding compared to ordinary people. After all, not everyone could compare to Liu Qing Yun.

"Senior Liu Qing Yun, is the Informatics Olympiad difficult?"
On the way to the computer lab, Han Jiang Yue, with her cheerful and lively personality, fanned herself with her small hand and asked curiously. In middle school, she had participated in the Math Olympiad. However, she couldn't even pass the Nan Shi City-level selection round. Facing Liu Qing Yun, who had won the National Special Prize in the Informatics Olympiad and was about to represent Dragon Nation in the International Informatics Olympiad in August, Han Jiang Yue naturally admired him greatly.

Why did she choose the Informatics Olympiad just now? Because there were fewer people on this side! Before she arrived, only Su Yun Xuan next to her had proactively chosen the Informatics competition. An Informatics competition tutor teacher, a senior who had just won the National Special Prize in the Informatics Olympiad. If she participated, wouldn't she receive more attention and tutoring? With this little scheme, Han Jiang Yue chose the Informatics Olympiad, with which she was unfamiliar.

Hearing Liu Qing Yun's answer, he smiled.
"Not difficult."
"As long as you think more normally and diligently type lines of code for practice, the Informatics Olympiad is actually not difficult at all."

Liu Qing Yun, facing the two junior students, had a bit of a master's aura. It was like junior students seeing a school-wide famous big shot who had been admitted to Qingbei on the road. He himself didn't realize that the naive and timid Liu Qing Yun of the past was long gone. After following Teacher Xu and witnessing many "grand scenes," and then personally creating some "grand scenes" himself. Liu Qing Yun's state of mind could be said to have reached a new level. Now looking back at the Informatics Olympiad he participated in? Liu Qing Yun felt that it was truly not difficult at all.

The lively Han Jiang Yue heard Liu Qing Yun's answer, and her eyes lit up.
"Really?"
"Then I must try it!"
Only Su Yun Xuan, walking beside her, had an awkward expression.
"Not difficult?"
"It would be a ghost if it wasn't difficult!"
"I've been exposed to programming since ninth grade, and even now I can only write a few simple lines of code."
"Anything slightly more advanced in algorithms or data structures, just looking at it gives me a headache."
However, he only thought these words to himself. Su Yun Xuan knew that with Senior Liu Qing Yun's level, being able to represent the entire Dragon Nation in the International Informatics Olympiad, the exam questions were naturally not difficult for him! Only this little girl beside him was so innocent and sweet.

Su Yun Xuan didn't know Han Jiang Yue; they weren't students from the same middle school. He just felt that Han Jiang Yue thought things too simply. Although Teacher Xu seemed amiable and approachable, he was still a teacher at Zhen Hua. Su Yun Xuan and Han Jiang Yue were fourteen or fifteen-year-old teenagers, and this was their first time interacting with him, so they were still a bit nervous. Besides the initial two sentences with Teacher Xu, they then revolved around Senior Liu Qing Yun. After all, they had never studied under Teacher Xu and didn't know what kind of teacher this Informatics Olympiad coach of Zhen Hua High School was. Was he strict? Did he have a bad temper? Did he often scold people? They knew nothing at all.

Arriving at the school's computer lab, Teacher Xu turned on three computers.
"You show off your skills for your junior students first."
Teacher Xu smiled and patted Liu Qing Yun's shoulder. Hearing Teacher Xu's instruction, Liu Qing Yun smiled and sat down, his fingers lightly tapping the keyboard, typing lines of code continuously. Just a moment later. The computer in front of him, along with the two other computers beside it. Suddenly, a large, colorful text appeared on the screen, continuously moving.
"Welcome Su Yun Xuan and Han Jiang Yue."
The scrolling subtitles also had background music.

Standing behind Liu Qing Yun, Su Yun Xuan and Han Jiang Yue's eyes widened, looking at the three computers displaying the scrolling subtitles in perfect sync. Their curiosity and eagerness to learn were immediately aroused.
"How magical!"
Han Jiang Yue had never seen such a scene before? She only felt that Senior Liu Qing Yun was like a skilled magician, casually conjuring a magic trick. Initially, she only came to watch because there were fewer people with Teacher Xu and Liu Qing Yun, and she was curious about the Informatics Olympiad. But after Liu Qing Yun's display of skill, Han Jiang Yue truly developed a desire to learn computer science.

"Senior Liu Qing Yun is so amazing!" Su Yun Xuan sighed.
Unlike Han Jiang Yue, who knew nothing at all, Su Yun Xuan had a basic understanding of computer science and programming. Precisely because he understood a little, he was even more astonished by Liu Qing Yun's strength. Su Yun Xuan pondered to himself. The welcome subtitles and background music that Senior Liu Qing Yun displayed on the computer were not an overly complex technique. He thought to himself that if he were given time, he could also do it. But the time consumed would definitely be very long. Moreover, the lines of code used would certainly be much more than Liu Qing Yun's. It would be impossible to do it so effortlessly and comfortably.

In Su Yun Xuan's heart, his interest in the Informatics competition grew a few degrees thicker.

From beginning to end, Teacher Xu did not intervene, entrusting all this work to Liu Qing Yun. He was like a hands-off boss. Liu Qing Yun had grown up and could handle everything himself. He watched him teach Su Yun Xuan slightly more advanced programming knowledge, while also teaching Han Jiang Yue the simplest things.

Teacher Xu looked at Liu Qing Yun, as if seeing himself back then in Jin Ya Academy's computer lab teaching Liu Qing Yun. Perhaps, this was the original appearance of teaching and learning. The inheritance of the flame of human knowledge has never been grand or glorious. Instead, it quietly permeated, leaving no trace.

...

After the programming experience curriculum ended, Su Yun Xuan and Han Jiang Yue became close with Liu Qing Yun.
"Programming is so interesting!"
Leaving the computer lab, Han Jiang Yue jumped for joy and cheered, completely unaffected by the heat outside.

"Senior Liu Qing Yun, thank you, just listening to you talk a little about advanced techniques, I already feel like I'm much better than before!" Su Yun Xuan said with a smile, "After I go back today, I must start practicing to digest this knowledge."

Suddenly, Han Jiang Yue stomped her feet.
"No!"
"Our Informatics club has too few members!"
"I'm going to drag all my best friends here!"
