Extra 3: My Sister Who Stayed Out All Night
There is a professional elective course in the afternoon, which is strongly related to cutting-edge computer technology.
In the large classroom, the topic was blockchain technology.
The two of them arrived early, and Ji Ling habitually took the back window seat.
This course keeps pace with the times. There is no textbook. The lectures rely entirely on the teacher's courseware and interpretation of the latest papers, as well as actual case demonstrations and analysis. The whole class is full of practical information.
Lower grade students are allowed to attend classes. There is a stack of simple stools at the door, and lower grade students can use the computers of seniors to study.
Therefore, many students took advantage of this class to pass themselves off as real students and brought their girlfriends on dates openly.
Secretly holding hands under the table.
"Sister Ji Ling, where does Gu Xing usually sit?"
It was the first time that Ruan Xingmian saw a tiered computer classroom.
Like a high school multimedia classroom.
One grid can accommodate two people, which is very suitable for dating.
Ji Ling frowned, then raised her eyebrows and asked, "Are you sure you want to go to his place?"
"No, no, I just got rejected. I'll just watch him from afar."
Ji Ling stared at her profile, wondering what tricks this girl was playing.
After students entered the classroom one after another, Ji Ling discovered that this guy was taking notes on people.
She has three questions for each person.
who is he.
How is your relationship with Gu Xing?
Why is the relationship bad?
She wrote it all down in her memo.
"Boss Yue."
"Hello, Mr. Yue."
The male classmates passing by the back seat would basically say hello before leaving, mistaking her for Ruan Xingyue.
For the first time, Ruan Xingmian felt how popular her sister was.
"Xingyue..." an ecstatic voice rang out, "Aren't you going to hold a company meeting today?"
The voice seemed familiar. It often made harassing phone calls to her sister.
Ruan Xingmian hadn't finished taking notes yet, and her hair covered her facial features.
The man sat down next to them and had a lot to say.
Chattering like a duck.
"Hello, I'm not my sister. Did you see clearly?" Ruan Xingmian looked up at him coldly. She really couldn't stand his ambiguous and intimate voice.
Suddenly, my eyes lit up—Gu woke up.
He walked in side by side with the teacher. The whole classroom fell silent and the students all looked towards the door.
Gu Xing sat in the front seat, put his schoolbag down first, and then spoke to the teacher.
The teacher looked elegant and handsome, but his hair was messy and he looked a little unkempt.
"Are you Xingyue's sister?" The duck next to her seemed very excited. "You sisters look quite similar."
"Hello, sister. My name is Lu Tian." He introduced himself enthusiastically.
"oh."
Ruan Xingmian responded coldly, his eyes following Gu Xing's back, watching his every move.
I feel so happy.
It would be great if she could sit next to Gu Xing one day.
"Has your sister ever told you about me? I'm Lu Tian, from the Lu Group..."
"This... brother," he was about to say handsome, but after turning around and taking a closer look, he found he wasn't handsome at all. Ruan Xingmian interrupted him mercilessly, "You're a bit noisy."
Brother-in-law is half a brother, Lu Tian happily shut up.
As soon as the bell rang, the teacher left Gu Xing's seat and started the class.
Ruan Xingmian didn't understand a word he said. He stared at his beloved with his hands propped up, his heart bubbling with happiness.
After three years of studying hard, I have imagined this scene so many times that it feels like a dream.
You can see Gu Xing by looking up.
Even though it was just the back of the head, I was so happy that I wanted to fly.
"Regarding the application of blockchain technology in the financial sector, the collaboration between Gu Xing's team and Lu's Group has been very successful. Now, we will hand over the floor to team leader Gu Xing. Teacher Gu, please."
Ji Ling snorted softly: "Teacher Qin is really racking his brains to outsource teaching. He should get half of Gu Xing's salary."
"Xingyue is here too?" Teacher Qin looked up and back.
Gu Xing came on stage and looked over in the direction he was looking.
Ruan Xingmian confirmed that their eyes met.
"Xingyue, come up too." Teacher Qin waved at her.
"She is not Ruan Xingyue." Gu Xing took out the prepared materials, stood next to Teacher Qin, and his deep eyes swept across the last row lightly.
Ruan Xingmian's heart stopped for a second when he looked at her. She folded her arms and straightened her back, sitting like a primary school student.
"Are you sure it's not?" Qin Zhen raised his glasses, wanting to see more closely.
The apprentice's gaze shifted coldly over, motioning him to make room.
"Oh, I'll be right down."
Qin Zhen strode down from the podium and headed straight towards Ruan Xingmian.
He greeted Ruan Xingmian with his hands behind his back.
"Don't tell me, they look alike from a distance and up close too. Are you Ruan Xingyue's sister?"
"Yeah!" Still Gu Xing's future girlfriend.
Ruan Xingmian responded to the teacher calmly, "Hello, Teacher Qin."
"Well, hello."
"Blockchain technology is used in the financial field," Gu Xing's cool voice swept across countless ears, instantly soothing the sweltering heat of autumn. "It mainly focuses on pain points such as 'cumbersome reconciliation,' 'risk of data tampering,' and 'low audit efficiency.'"
I don't understand, but it's so handsome.
"The Lu Group has 108 subsidiaries in 36 other countries, each with its own independent accounting system. At month-end reconciliation, bank statements, invoices, and internal transfer records often don't match. Manual verification alone can take up 300 people a day, and financial reporting is often delayed due to timing differences in certain cross-border payments and exchange rate errors."
Gu Xing calmly opened the PPT. "With the full support of Lu Group's CFO, Wen Xinlan, and our team's leading development of the financial alliance chain, we can put all accounts on the chain."
"Next, please watch the demonstration."
"Each subsidiary's receipts and expenditure vouchers, including invoices, contracts, and bank receipts, are automatically uploaded to the blockchain when they are generated. The hash value is bound to the original data. Anyone who wants to change an account not only needs to tamper with the company's node, but also simultaneously break into the backup nodes of the other 108 subsidiaries. The cost of forgery is "impossible."
“Cross-border transfers no longer rely on interbank forwarding, with on-chain smart contracts automatically triggering…”
…
"Every time Gu Xing stands on the platform and gives a lecture, I have the urge to marry him." Ji Ling sighed with his arms folded.
An intellectual impulse.
"Ah?" Ruan Xingmian turned around excitedly, "Sister Ji Ling?"
Ji Ling quickly covered his mouth and said, "Damn, my vest fell off."
She thought the girl would leave angrily, but she came closer with a smile: "I'm more adventurous than you. I just gave birth to three children in my mind. He has to carry one on his back and hold the other, and he has to tutor the older one. Hehehe..."
Lu Tian, who shamelessly refused to change his seat: "..." Is sister Ruan Xingyue so brave?
After a long class, Ruan Xingmian felt sore in the waist and back, but he was also satisfied.
"The seventh and eighth classes are professional courses in a small classroom. I can't take you in."
"It's okay, Sister Ji Ling. I'll wait for you outside on the lawn after class."
Ji Ling: “…”
What's the point of her pestering him instead of staying close to Gu Xing?
"You heard everything just now. I like Gu Xing too. Do you still want to play with me?" She didn't believe that a girl could be so generous.
"What's the big deal? Gu Xing is nothing..."
"Ji Ling."
Gu Xing, who was nothing, stood behind them and spoke.
Ruan Xingmian turned around reflexively, the second half of the words stuck in her throat, her face flushed red, and she was so anxious that she was speechless.
"I've assigned you the algorithm task," he said.
"Oh, okay." Ji Ling opened it and took a look. "What about the Xingyue part?"
"I'll do her part, you don't have to worry about it."
He glanced at Ruan Xingmian, who was blushing, and walked away from the two of them calmly.
"He's so weird. He even reminded me about the algorithm task today." Ji Ling poked at the phone screen, feeling puzzled. "Before, he would just be cold and talk to me in the group."
@季听, the task is due at 8 PM tomorrow.
"It's over, Sister Ji Ling, he must have heard the first half of my sentence!" Ruan Xingmian was so upset that she wanted to cry.
The small classrooms in Duxing Building are on the second floor.
The windows are bright and the view is excellent. Sitting by the window, you can look up and see the scenery of the small garden.
And the little beauty fidgeting in the early autumn scenery.
Ji Ling knew that Ruan Xingmian was playing with his phone there, and frantically searched on Baidu for how to pursue the cold and aloof Ruan Xingmian.
She also observed that Gu Xing looked there more than ten times.
At night, Ruan Xingmian stayed in the dormitory.
Sleeping in her sister Ruan Xingyue's bed.
Ji Ling really likes living in the dormitory, it is more comfortable than living at home.
But she was timid and afraid of the dark, so Ruan Xingyue didn't live in the dormitory, so she went home.
It just so happened that she didn't want to go home today, so she "reluctantly" took Ruan Xingmian back.
There were only her and Ruan Xingyue's things in the dormitory.
All four beds were filled to the brim with the two of them.
"Wow." Ruan Xingmian exclaimed as she entered the room, "Are you and my sister so messed up?"
Ruan Xingmian rolled up his sleeves and got to work.
Made her sister's bed neatly.
Ji Ling sighed, this little girl has strong hands-on skills.
It's not just about acting coquettishly and calling me sister.
"Sister, how do you tell me to ask Gu Xing out and apologize to him? I only finished the first half of my sentence this afternoon, saying that he was nothing, and I think he must have heard it."
It's nice to have someone accompany you, but it's a bit noisy.
Ji Ling was so sleepy that he gave random suggestions with his eyes closed, "He will be back to the dormitory before twelve o'clock, you can go and guard him."
"good!"
Ji Ling took off the blindfold, but he didn't expect that the girl really went.
