？？？ Liu Feng’s head was filled with question marks.

He looked at Lin Xian, then at Huang Que.

This…

What kind of ambiguous atmosphere was this?

Were they flirting right in front of him?

“Ahem.”

He coughed lightly twice, then picked up his phone and headed for the door.

“Well, I’m going to the restroom. You guys chat.”

With that, he hurried out the door.

Lin Xian looked at Huang Que.

“You—”

Before he could utter a single word, Liu Feng rushed back in, grabbed a roll of toilet paper, and dashed out again.

“I thought about it, and I think I need to take a bigger one. I’m slow in the restroom. I usually don’t get up unless I’ve been sitting there for half an hour. Uh… sometimes it takes an hour. Anyway, I’m leaving now.”

*Bang.*

He closed the door behind him.

“…”

Lin Xian stared at the closed laboratory door, turned his head, and looked at Huang Que.

It seemed that he had indeed imagined things.

Or maybe it was because Huang Que was standing in the sunlight.

That was why her eyes seemed to have a duller color.

Now that Huang Que had walked from the corridor into the lab, into the shadows, her pupils were as bright as ever… he wondered what the mechanism was.

“I got the Genius Club invitation.”

Lin Xian said softly.

He had originally wanted to ask why Huang Que happened to be here, but Liu Feng had interrupted him. Oh well, he might as well get straight to the point.

“I don’t know what to say. Your hints were definitely on point. It just proves that I didn’t spend enough time looking in the mirror. If I had listened to you and stared at the mirror for 24 hours straight, I would have solved the puzzle a long time ago.”

Huang Que smiled and walked to the middle of the lab, stroking the space-time clock that Liu Feng had placed on the experimental platform.

“Hindsight is meaningless. Besides, no normal person would stare at a mirror for 24 hours. And getting the invitation now isn’t too late.”

“Or… even if you had managed to get it earlier by some fluke, it wouldn’t have done you much good. After all, the invitation is only the first step. If you don’t answer those three questions correctly, you still can’t join the Genius Club.”

“Life is like that. You never know if you’re taking the right or wrong step, or what you should persist with and what you should give up on halfway. Like I told you before, Lin Xian, if it’s right, keep doing it; if it’s wrong, go all the way. The only thing you can’t do is be timid.”

Lin Xian pulled open his tracksuit jacket, revealing the hoodie underneath.

On his chest was pinned the golden Genius Club insignia.

He pointed to the insignia and showed it to Huang Que.

“I’m more curious about whether I got this Genius Club invitation through normal channels or if there was some cheating involved. The way I see it… people who can get the invitation should be able to answer those three questions easily, not be as clueless as I am.”

“After all… it’s already very difficult to get the Genius Club invitation. Shouldn’t there be no such thing as failing the test? At least, the Genius Club has been so well hidden for so many years, without a single clue being exposed. That means everyone who gets an invitation has actually passed the three tests?”

Huang Que blinked her azure eyes.

“You’re right about that. People who get the invitation can definitely answer the three test questions. It’s an inevitable cause-and-effect relationship. As for where your invitation came from… I think you know in your heart, but don’t ask me for details. I can’t tell you.”

Lin Xian nodded.

He zipped up his jacket and stopped asking.

“I’ll find the answer myself.”

Hearing this, Huang Que smiled meaningfully, but said nothing.

Lin Xian then remembered the original question. He looked up at Huang Que.

“Judging from what Liu Feng said before he was interrupted, you came here earlier? Is there something you wanted to talk to me about?”

Huang Que nodded.

“I’d like to invite you to go to Copenhagen with me.”

Copenhagen?

Lin Xian recognized the familiar place name.

Copenhagen was the capital of Denmark and the country’s largest city. It had been named the most livable city in the world and one of the happiest cities in the world.

The climate here was unique, with mild temperatures in all four seasons. The highest temperature in summer was around 22 degrees Celsius, and the lowest temperature in winter was only a few degrees below zero. It was indeed very livable.

However, Lin Xian’s familiarity with the city didn’t come from tourism or the climate, but from one of the greatest debates in the history of human science—

The century-long debate between Albert Einstein and Niels Bohr.

It was a debate about quantum mechanics, with almost all of the smartest scientists in human history participating, each with their own opinion, arguing fiercely.

Niels Bohr was the founder of the Copenhagen school and made significant contributions to the creation and development of the modern scientific discipline of quantum mechanics.

It was worth mentioning that, to this day, there was no conclusion as to who won or lost this century-long debate.

In 2022, because the Nobel Prize in Physics was awarded to the field of quantum entanglement experiments, which had been highly anticipated for many years, many people believed that the Copenhagen school had finally won and Einstein had lost.

But in reality, quantum mechanics was still in a rather mysterious state, and most theories could not be confirmed experimentally, so there was no evidence that Einstein was wrong.

Many scholars even believed that both Einstein and the Copenhagen school were wrong.

In short.

Lin Xian couldn’t understand or learn from these debates between the smartest geniuses in human history. He only remembered the name Copenhagen because of this debate.

And now, Huang Que specifically wanted to go to Copenhagen.

Lin Xian felt…

Could there be some deeper meaning?

Thinking of the "Sad Einstein" painting whose code hadn’t been cracked yet, and of the geniuses who stood at the pinnacle of humanity during the Copenhagen debate in the last century.

Could it be that there was some secret in Copenhagen?

Or was Huang Que going to give him some hint?

However…

Just as Lin Xian was racking his brains over the riddle, Huang Que chuckled at his frowning face.

“Lin Xian, you don’t have to think too deeply about it.”

“This time I’m inviting you to go to Copenhagen for no deep reason, no hint, and no connection to the Genius Club, the Millennium Stake, space-time particles, or anything else.”

“I just… simply want to stroll around that beautiful city.”

Lin Xian was surprised.

This didn’t seem like Huang Que’s style.

Was she such an elegant person?

Let alone her, even Zhao Yingjun wasn’t like this… He felt that hobbies like travel and food were completely unrelated to people like them.

Zhao Yingjun was a complete career woman, focused on her work.

Huang Que was even more decisive, taking care of the spaceplane and commanding the entire capture plan on her own.

It was hard to imagine that a woman like Huang Que would go abroad simply because she wanted to stroll around or travel.

“Have you been to Copenhagen before?” Lin Xian asked.

“No.”

Huang Que shook her head.

“Because I haven’t been there, I want to see it.”

“So… is it okay?”

Her blue, glass-like pupils stared at Lin Xian.

“Can you go with me?”

Lin Xian looked at Huang Que.

Finally.

He nodded.

“Okay.”

…

“This, this is a little weird!”

After Huang Que left the lab, Liu Feng quickly slipped back in.

After hearing Lin Xian’s account of Huang Que’s invitation, Liu Feng looked incredulous.

“This doesn’t seem like something Huang Que would do… It’s too coy, even inviting you on a trip abroad. We haven’t known Huang Que for just a day or two. We know each other pretty well.”

“If it were a girl like Chu Anqing, she might invite you on a trip, but Huang Que… I feel like unless pigs fly, or she… Well, it can’t be that she’s taken a fancy to you, right? I feel like that’s impossible. How should I put it, Lin Xian…”

Liu Feng frowned, thought for a while, then looked up and said solemnly,

“I did say before that the way Huang Que looked at you was weird, and I said it was kind of sticky. But after spending more time with you, I realized I might have misunderstood Huang Que… Don’t take this the wrong way, Lin Xian, but my latest feeling is that Huang Que doesn’t actually like you…”

“The way she looks at you is a very complicated emotion. It’s like she’s looking at you, but not you. Do you understand what I mean?”

“Do *you* understand what you mean?” Lin Xian retorted.

“Who can understand what you’re saying when it’s all so messed up?”

“Besides, I already told you not to think that every woman who looks at me likes me or has taken a fancy to me. I’m really not as charming as you think. Huang Que… how should I put it? My feelings for her are also very subtle.”

Lin Xian was telling the truth.

He knew that Huang Que was 99% Zhao Yingjun who had traveled back from some future timeline.

But.

He still couldn’t see these two people as the same person.

“Huang Que looks at you like she looks at her son!”

Liu Feng blurted out.

“Yes, yes, yes! That’s the look she gives her disappointing son!”

“Huh?”

Lin Xian stared blankly at Liu Feng.

“You’re really going too far. Can you put your gossiping heart away and focus on research? You can’t possibly think you’re an expert on relationships just because you’ve been in love once, right?”

“Forget it, I won’t interfere in your relationship.”

Liu Feng waved his hand.

“So what do you think? You still agreed to go to Copenhagen with her, didn’t you?”

Lin Xian was silent for a few seconds, then continued,

“That’s because I feel…”

“This time, Huang Que is still lying.”

He looked up at Liu Feng.

“Before our spaceplane took off, I asked her why she had to take Chu Anqing into space, and whether it was because the space-time particles were coming for Chu Anqing.”

“She casually denied it at the time, saying it was just for a backup, one more person, one more strength. But you know the truth. Huang Que knew all along that Chu Anqing was the ultimate weapon for capturing space-time particles, and only she could see the space-time particles when their energy was exhausted.”

“Of course, we understand that these things may not have been said because of the space-time law of forced avoidance, so there’s no need to dwell on them now.”

“So, considering it from the same perspective, this time Huang Que also casually said she was going to travel, to stroll around. But in reality? Perhaps… the truth is far from that simple. She must have some plan.”

Liu Feng listened, thoughtfully.

“I see… In that case, it’s definitely worth going to Copenhagen with Huang Que. Anyway, Huang Que wouldn’t harm you. At most, she’ll just lie to you, and most of them are harmless lies, so she definitely won’t harm you.”

“So, go ahead and feel at ease. Huang Que’s appearance is always like a timely rain, bringing us key hints every time. Look, aren’t you worried about what the space-time coordinates are? Maybe Huang Que will say she can’t say it, but she’ll actually imply it to you and give you the answer through her actions.”

“After all… after all, it’s Copenhagen. For many science enthusiasts, it’s a pilgrimage site. Maybe after you go, you’ll really be able to find something.”

Lin Xian nodded.

“Even if she deceives me, it doesn’t matter.”

He waved goodbye to Liu Feng and left the lab.

“I owe her too much.”

…

The next day.

Pudong Airport.

Lin Xian was pushing the luggage of both of them, following behind Huang Que, who was wearing high heels, like a little follower.

Huang Que seemed very relaxed.

Although she was still wearing the high heels that were welded to her feet and the sapphire earrings that were welded to her earlobes,

Huang Que’s outfit today was much more casual in other aspects.

There was no workplace element.

She was wearing big sunglasses and a beanie.

She was really dressed like a wealthy woman going abroad for tourism.

But Lin Xian wasn’t relaxed at all…

He didn’t think it was a good time to go abroad right now, nor did he think it was a time when he could travel.

If it wasn’t to go along with Huang Que, Lin Xian would definitely not go abroad at this moment.

VV’s message told him that Jask, the smiling tiger, was not as friendly as he seemed;

Kevin Walker, he knew from the beginning that he wanted to capture space-time particles. After the sky battle, there was no news, and he didn’t know what his intentions were;

Copernicus, too, he should know that he killed Ji Xinshui, right? But there was no sign of activity so far;

These people all had ulterior motives, but no action, which made Lin Xian feel tense and worried… Fearing that each of them was planning something big.

But…

He looked up at Huang Que, who was carrying a handbag and walking towards the boarding gate in big strides.

With Huang Que’s seal of approval, he wasn’t worried about the safety of this trip, but he couldn’t help but wonder what Huang Que’s purpose was this time.

First-class boarding had a special fast lane. Huang Que verified the tickets first, and Lin Xian glanced at them.

Name: Huang Que.

…

So her name really was Huang Que!

But it was understandable. This woman had the means to take care of the Jiuquan Satellite Launch Center and the means to take care of the spaceplane.

In comparison, it was naturally much easier to have the relevant departments “supplement” her with an ID card and a set of identity information, with no effort at all.

Lin Xian wanted to take a look at the age on the ID card.

But after verifying the ticket, Huang Que directly picked up the ID card and put it into her handbag along with the boarding pass, then looked back at Lin Xian.

“It’s impolite to peek at a woman’s age.”

Lin Xian didn’t care.

“Anyway, the age on your certificate must be fake, just like your name.”

Huang Que chuckled.

“That’s not necessarily true.”

With that, she continued to walk forward in her high heels.

*Boom—*

It was the familiar sense of weightlessness again, as the Boeing aircraft took off.

Lin Xian didn’t know how many times he had been pushed by this weightlessness during this period. It was really like what Gao Yang said, he spent more time in the sky than on the ground.

The direct flight from Donghai to Copenhagen took 13 hours, almost half the globe.

In the spaceplane, which was flying at the first cosmic velocity, it only took 40 minutes to fly over half the globe.

But now, it took 13 long hours.

Fortunately, because of the time difference, it was still morning when the two of them landed in Copenhagen, so they didn’t have to adjust to the time difference at all.

After the plane landed, they completed various procedures.

Lin Xian was still pushing the luggage of both of them, walking out of the airport aviation building, bathed in the sunlight. The two of them looked up at the not-so-warm sun.

“Where are we going now?” Lin Xian asked.

“Since you’ve always wanted to come, there must be some place you want to stroll around, right?”

However, to Lin Xian’s surprise.

Huang Que gently shook her head.

“I don’t know Copenhagen at all. Wherever you want to go, we’ll go.”

This stumped Lin Xian.

He was originally accompanying Huang Que here, and he thought Huang Que must have some plan, some purpose, or some important clue to give him before coming to Copenhagen.

Could it be that he had really guessed wrong?

He chuckled and looked at Huang Que, who was wearing a blue scarf.

“Since you don’t know anything about Copenhagen, then why did you want to come so much?”

“Because there was a man who said he would take me here to see it. He really liked Copenhagen.”

Huang Que looked away from the sky and looked at Lin Xian.

“But he broke his promise.”

The smile on Lin Xian’s face froze, then faded.

He closed his mouth.

After a few seconds, he tentatively asked.

“It wouldn’t be me, would it?”

“Hehe.”

Huang Que laughed inexplicably.

The breeze of a foreign country, Denmark, blew, ruffling the green silk of Huang Que’s hat brim.

“Of course it’s not you. You didn’t break your promise.”

She turned her head and looked again at the distant high-rise buildings of Copenhagen.

“Aren’t you… bringing me here?”
