It's usually used to describe a scumbag.

"But be careful not to become a central air conditioner," Yan Yiting said.

"what?"

"Maybe it's because I'm getting older and have a different perspective," Yan Yiting said. "Being friends without dating is a privilege reserved for young people. Young people like Lu Aiai don't mind being teased, but I, who am aiming for marriage, can't stand that."

"Either we date or we break up, right? If we take it to extremes, then it's not dating, it's a blind date," Chen Ya asked with a smile.

"Who doesn't want to be in a relationship? If it weren't for my age, who wouldn't want to have a fantasy romance? But a fantasy is just a fantasy," Yan Yiting said with a bitter face. "What can I do? I'm too old. I really envy Ai Ai..."

She glanced at Lu Aiai, who was tilting her head and looking completely bewildered, at the beginning of the scene, and sighed sincerely.

"Don't try this on a 30-year-old woman. Lingering feelings are the worst." Yan Yiting said, then seemed to recall an unpleasant memory, her temple twitching. "If you're not going to date, then get lost! Saying we're friends just means you see me as a fish in a pond..."

Chen Ya was slightly surprised: "You're 30 years old?"

"Yeah, what's wrong? Can't you tell?" Yan Yiting put her hands on her hips.

“I can’t tell,” Chen Ya shook his head. “You look no more than 29.”

Yan Yiting blushed and spat. Lu Aiai coughed softly beside her and whispered, "Yiting, you're already married."

Yan Yiting retorted angrily, "I know I'm married! I'm not gloating!"

Lu Aiai was pleased that Yan Yiting had self-awareness and nodded to herself.

Yan Yiting stared at Lu Aiai with a dark expression for a long time, but quickly let it go.

Lu Ai'ai's interest in other boys was exactly what she wanted. Besides, this boy had been carefully selected by Old Master Yang and was the perfect partner for her.

"Um, Mr. Bai Yujing, what do you usually do for work?" Yan Yiting asked, turning her head.

"Currently, I'm running a company," Chen Ya said. "It's quite close to Peking University."

"I heard from Professor Yang that you're starting a business. What kind of project is it? Is it related to scientific research?"

Chen Ya shook his head: "We're currently working on a game."

"It's actually about making games?" Yan Yiting was slightly surprised. She had also read Bai Yujing's paper. Although she didn't understand it very well, she could still tell that it had nothing to do with games.

"I made a game before called 'Sheep'."

Yan Yiting almost stumbled: "You actually made 'Sheep, Sheep'?!"

The Qingming Festival holiday is not long over, and Yan Yiting still remembers the fear of being controlled during the holiday.

Back then, she complained about the game for a long time in a small group chat, wishing she could tear the instigator to pieces. That painful memory is still fresh in her mind.

But when Chen Ya looked at her with an innocent expression, Yan Yiting suddenly felt that perhaps Chen Ya had his own reasons for playing this game.

Lu Aiai, who was standing next to her, suddenly asked, "So, don't you have a girlfriend who's a senior executive at a big company?"

"Huh?" Yan Yiting was taken aback, not understanding what she was talking about. "What, a girlfriend who's a high-ranking executive at a big company?"

"He is favored by beautiful female executives from large corporations, who are his business partners and life companions."

Yan Yiting looked at her speechlessly: "Ai'ai, what kind of misconception is this? When did you start watching domestic TV dramas? Didn't you never watch TV?"

"What TV?" Lu Aiai turned her head, looking blank.

Yan Yiting covered her head and said, "Romantic entanglements between company bosses and partners, or beautiful female executives of big companies—that's something you only see in domestic romance dramas!"

"Really?" Lu Aiai blinked.

“Yeah, there aren’t that many beautiful female executives in big companies. It’s all made up in TV dramas.” Yan Yiting rubbed her forehead.

Lu Aiai's bright eyes turned to Chen Ya, meeting his gaze: "You're not dating any executives at big companies?"

Chen Ya said calmly, "It's just a simple friendship."

"friend?"

"Yeah, just some close friends."

Yan Yiting suddenly turned around and looked at Chen Ya:

"Wow, there really are beautiful female executives from big companies!"

"Yes," Lu Aiai and Chen Ya answered seriously at the same time.

Yan Yiting is truly at her wit's end.

Chen Ya and Gu Yuqing are not officially boyfriend and girlfriend. Although they are getting very close and maintain an ambiguous understanding, they still cannot officially declare themselves as boyfriend and girlfriend.

The main issue is the pressure from Gu Yuqing's family; they believe Gu Yuqing can never date or get married.

If she gets caught red-handed, Gu Yuqing's life trajectory will be rewritten.

So no matter where he went, Chen Ya insisted that he and Gu Yuqing were just friends.

Despite the various reasons, Lu Aiai heard it in a completely different way than what Chen Ya thought.

After hearing Chen Ya's denial, she felt incredibly light, as if her heart was about to float into the air, and a strange and joyful emotion filled her body.

As for why Chen Ya and Gu Yuqing kissed and were so intimate, it's no longer important to her now, or rather, she has selectively forgotten it.

"I actually need Professor Yang's help this time," Chen Ya said. "I want to make some breakthroughs in room temperature superconductivity with my recent research, and I need to use the laboratory of a mature team in China."

Lu Ai'ai's mind was filled with "borrow, borrow, borrow," but she remained expressionless because she had forgotten how to speak.

"Huh? Aren't you from a game company? Why would you want to do this?" Yan Yiting asked curiously. "Aren't you guys... busy with your work?"

What she really wanted to ask was why Chen Ya's workload was so light, and whether he had run out of games to work on.

Chen Ya frankly stated, "Our company's next step requires major breakthroughs in several technological areas, including room temperature superconductivity. If we want the company to develop smoothly, we need to start planning now."

Yan Yiting has always been immersed in an academic environment and doesn't know much about the application of technology to civilian use. She especially doesn't understand how a game company could be related to room temperature superconductivity.

"Room temperature superconductivity, if I remember correctly, it only refers to achieving superconductivity at room temperature, right? What does this have to do with your company's business?"

Chen Ya laughed and said, "Of course it's related. In fact, it's related to everyone in the world."

"What do you mean?" Yan Yiting looked at Chen Ya with a puzzled expression.

All she knew was that room-temperature superconductivity was attracting a lot of attention in the academic community, and every breakthrough was big news; some even said it would be the fuse for the Fourth Industrial Revolution.

But she didn't know exactly why this was happening.

“Well, to understand room temperature superconductivity, you first need to know some background information,” Chen Ya said. “You know about direct current and alternating current, right?”

Yan Yiting rolled her eyes: "Of course I know that. It's middle school knowledge, right? Direct current is current that flows from the positive terminal to the negative terminal without changing its direction or magnitude. Alternating current is current that changes periodically between the positive and negative terminals."

Chen Ya nodded: "Hmm, that's a very physics-oriented answer. So, do you know which of the electrical appliances you use use alternating current (AC) and which use direct current (DC)?"

"Uh……"

Caught off guard by the question, Yan Yiting was initially taken aback, but quickly began counting on her fingers:

"Washing machines, refrigerators, air conditioners, light bulbs... these all use alternating current (AC), right? In fact, almost all household appliances use AC. Computers use direct current (DC)?"

Chen Ya took out his phone and waved it in front of her: "And this too."

"Oh right, and cell phones too."

Chen Ya nodded and said, "Mobile phones and computers, these kinds of electrical appliances that contain precision components, need to identify high and low potential differences, so they cannot use alternating current and therefore use direct current."

He paused for a moment, then added, "Actually, in the early days of human invention of electricity, there was a long debate between direct current and alternating current."

In the early days of electricity use, Edison's General Electric Company consistently promoted direct current (DC).

Direct current (DC) has a fatal weakness compared to alternating current (AC) – its voltage drops significantly over long distances.

With the technology at the time, the DC voltage was insufficient to light a light bulb if the distance exceeded one kilometer.

Therefore, General Motors invests heavily in power plants, building an average of one power plant per kilometer in cities.

At the time, Tesla was working as an electrical engineer under Edison. He pointed out the advantages of alternating current many times, but Edison ultimately did not adopt them due to commercial considerations.

Tesla later suffered a lot of unfair treatment at work (Edison was not a good boss), and eventually left in anger to join Westinghouse, where he promoted the commercialization of alternating current.

In an effort to combat alternating current (AC), Edison employed many underhanded tactics to demonize it, which initially greatly hindered its widespread adoption.

But thanks to a World's Fair, Westinghouse turned the tide and ultimately helped AC power achieve great success.

Due to the failure of direct current, Edison's General Electric Company's financial situation deteriorated sharply, eventually leading to its merger into General Electric.

"To understand room temperature superconductivity, we must first understand this case in order to gain a deeper understanding of its significance," Chen Ya said. "We all know that the reason why direct current fails is because of power loss, and the reason why power is lost is because there is resistance in the conductor."

Yan Yiting nodded repeatedly, and Chen Ya continued:

"Superconductivity is the phenomenon where the resistance of a conductor suddenly becomes zero under extremely low temperatures."

"But power transmission lines are so long, we can't possibly put a refrigerator on the entire line. But think about it, what would happen if superconductivity could be achieved at room temperature?"

Yan Yiting asked blankly, "Electricity prices... are going to drop?"

“That is certainly one aspect, but the significance goes far beyond that,” Chen Ya said. “If room temperature superconductivity can be achieved, it means that if I build a power station somewhere, it can transmit electricity to any place on Earth without any loss of power.”

Yan Yiting stared blankly for a while, then said, "It seems... quite shocking."

"On a smaller scale, it will greatly improve the domestic environment, transportation, and regional imbalances. On a larger scale, it will affect the international situation and fundamentally change the international energy landscape."

Yan Yiting hadn't thought that far ahead. All she could think of was that electricity prices were now uniform everywhere on Earth, and that no public intellectual was going to claim that electricity was completely free in any particular place.

After a moment of shock, Yan Yiting came to her senses and turned to look at Lu Aiai: "I never imagined that what Aiai did would have such great significance!"

Lu Aiai remained calm. She didn't imbue her work with any grand meaning; for her, research was simply research, and that was meaningful in itself.

Yan Yiting then asked Chen Ya, "Wait, you haven't said yet, what does this have to do with your company?"

Chen Ya smiled and said, "I mainly work on equipment. Superconducting materials are very important for the research and development of quantum computers."

Yan Yiting nodded. Actually, she didn't understand, but she just needed an answer.

Like many other women, when asked, "If my mother and I fell into the water, who would you save first?" they just want an answer.

She leaned close to Chen Ya's ear and said, "If you want to borrow her lab, you have to talk to her in person. What's the point of always making me relay messages?"

Chen Ya smiled bitterly.

He wanted to speak directly to Lu Aiai.

But someone had previously said they didn't want to communicate with him.

“I need to get her permission before I can speak to her directly.”

“Agreed,” Lu Aiai said almost immediately.

Without making a sound, Yan Yiting watched as the two men quickly moved closer to her and then pulled away from her by a distance.

Never before in her life had she felt so like a super-bright light bulb shining in the night sky.

Chapter 350 You have a younger sister?

Lu Aiai and Chen Ya seem to have resolved some kind of inner conflict.

Previously, the two had been tacitly avoiding each other's conversations, with Yan Yiting, the translator, acting as the middleman.

The two are now chatting enthusiastically, completely ignoring Yan Yiting, which is a clear case of using someone and then discarding them.

Yan Yiting felt a deep sense of melancholy. It was truly a case of "once the birds are gone, the good bow is put away." She could now deeply empathize with the phrase "discarded like worn-out shoes."

Does anyone in the family understand this?

Lu Aiai walked beside Chen Ya with her hands behind her back. Her back looked much more relaxed, and she also had a shyness that Yan Yiting had never noticed in her before.

In front of Yan Yiting, Chen Ya was chatting casually with Lu Aiai.

"How did you discover that the conclusion from the Gias Labs was unreliable?" Lu Aiai asked.

Chen Ya shrugged and said, "There are too many reasons, including but not limited to the Indian man's criminal record. Also, a certain materials stock abroad experienced a surge... and a certain congressman happened to make a high-profile investment..."

"You mean they're using hype to inflate stock prices for profit?" Lu Aiai asked, blinking.

She is naive, but not stupid; she knows all about the dark side of scientific research.

“It’s just speculation, after all, I have no evidence,” Chen Ya said. “However, I can confidently predict that in about a week, that stock will plummet and Gias’s paper will be retracted.”

As he spoke, Lu Ai'ai kept her eyes fixed on his face, as if she were getting to know a completely new Chen Ya, with a hint of admiration in her eyes.

"Did you buy it?" Lu Aiai asked, her expression blank, seemingly a little worried.

Chen Ya shook his head and smiled: "No, rushing in now would be like handing a knife to the enemy and letting them kill us. The initiative is in their hands, and we can't predict when they want to close the net."

Lu Aiai looked somewhat gloomy.
