Zhao Yingjun was also a little surprised.

She remembered that a few days ago, when Lin Xian went to the hospital to visit Xu Yiyi, Xu Yun politely asked him to leave, telling Lin Xian never to come looking for him again.

She had thought that would be the end of it.

But now, the way Professor Xu Yun was acting… to be so respectful and polite to Lin Xian was truly baffling.

Zhao Yingjun originally wanted to persuade Xu Yun, but seeing his eagerness, she gave up:

"Alright then, Professor Xu Yun, please come with me."

Zhao Yingjun stepped aside, signaling Xu Yun to exit the VIP room:

"Lin Xian's office is on the 17th floor. I'll take you there now."

Xu Yun nodded.

Without any hesitation, he strode out and entered the elevator with Zhao Yingjun.

…

The elevator doors closed and began to ascend.

The three vice presidents and Team Leader Wang stood dumbfounded at the entrance of the VIP room, still recovering from the shock.

The four exchanged glances, their expressions uncertain.

"What... what exactly is going on?"

One of the vice presidents spoke:

"Professor Xu Yun is highly respected and has always been calm and composed. This is the first time I've seen him so flustered, as if he's seen a ghost."

"Indeed..."

The other two vice presidents and Team Leader Wang echoed in agreement:

"We used to have to go to great lengths just to see Professor Xu Yun once. It's unbelievable that he would personally come here like this today."

"And he's going upstairs to find Lin Xian himself. What kind of treatment is that?"

"It can't be for the Rhine Cat, right? That would be ridiculous..."

Ding—

The elevator arrived at the 17th floor and the doors opened.

Lin Xian's office door was open, and Zhao Yingjun led Professor Xu Yun directly inside:

"Lin Xian, Professor Xu Yun is here to see you."

"Huh?"

Lin Xian was adjusting the Rhine Cat model on his computer.

He turned his head and saw Professor Xu Yun looking at him with a complex expression.

He naturally guessed Xu Yun's intentions and smiled slightly:

"Professor Xu, long time no see. Is your research going well?"

"Yes, very well."

Xu Yun didn't know what to say. He hesitated, turning his head to look at Zhao Yingjun.

Zhao Yingjun immediately understood and introduced Lin Xian to Xu Yun:

"Professor Xu Yun, this is Lin Xian. You've met before."

"Then... we won't disturb you. We'll go out first. Just call me if you need anything. I'll wait outside for you."

With that, she turned and left, closing the office door behind her.

Xu Yun walked over.

He locked the office door.

Only then did he turn to look at Lin Xian:

"Lin Xian, I appreciate you calling me 'Professor'... I hope you won't take my previous attitude to heart."

Lin Xian shook his head, indicating that he didn't mind:

"Professor Xu, since you've come to find me today, you must have read the manuscript I gave you, right? What do you think of the contents? Did it help you?"

Xu Yun nodded, recounting everything that had happened last night to Lin Xian in detail…

"Your manuscript is completely correct. Thanks to you, I've completely solved the ice crystal problem. We are now only one step away from completing a hibernation pod filling fluid that can be practically used."

"However..."

Professor Xu Yun looked troubled, hesitant to speak.

Lin Xian didn't know why Xu Yun had suddenly stopped talking:

"What's wrong, Professor Xu?"

"There are no outsiders here. You can say anything."

Xu Yun nodded, his expression serious:

"Lin Xian, I have a request."

He paused, asking earnestly and sincerely:

"Can you tell me… where did this manuscript come from?"

…

Faced with Xu Yun's question, Lin Xian fell silent.

He certainly wouldn't tell Xu Yun about the dream, but how could he get around this difficult question?

Lin Xian thought for a moment and shook his head:

"Professor Xu, if you want to obtain more information, it's best not to ask too many questions."

Upon hearing this, Xu Yun.

Numerous dangerous assumptions flashed through his mind.

"I... I understand."

Xu Yun swallowed, deciding to abandon his curiosity.

After all, his primary goal was to obtain the correct information. From the looks of it, Lin Xian was still willing to help him, so the question of the source was irrelevant:

"Thank you for still being willing to help me, Lin Xian."

"Don't worry, no matter what happens in the future, I will take responsibility for my own actions and will never reveal your involvement."

Lin Xian nodded and smiled.

This was good.

It saved him the trouble of explaining:

"Professor Xu, you just said that you are only one step away from completing the final hibernation pod filling fluid… have you encountered any difficulties?"

"Yes." Xu Yun quickly replied:

"I encountered some difficulties in the final stage of developing the hibernation pod filling fluid. I suspect that some of the chemical reaction formulas on the manuscript are incorrect."

"Oh, that's very possible."

Lin Xian casually said:

"Why don't you mark where the errors are? I'll find a chance to confirm them for you later?"

Xu Yun was genuinely surprised that Lin Xian would agree so readily.

He hadn't even made the request yet, and Lin Xian had directly offered to help him confirm it!

Thinking of the abandonment and betrayal he had experienced over the years.

Xu Yun was deeply moved:

"Lin Xian… I really don't know how to thank you enough."

"Professor Xu, you're too kind. It's just a small favor."

Professor Xu Yun sighed:

"Don't worry, Lin Xian, you are a benefactor to both me and Yiyi. I will definitely find a way to repay you!"

He suddenly realized:

"Oh, right, doesn't your MX company also want the authorization for that moisturizing chemical substance?"

"I can guarantee you… once the hibernation pod filling fluid is successfully developed, then I won't have any more concerns. I can give you that failed product."

…

Afterwards, Xu Yun took out the manuscript from his briefcase.

He had circled several obvious errors with a red pen.

Lin Xian accepted the manuscript and put it in a drawer to hide it temporarily. Then, he promised Professor Xu Yun that he would bring him the new manuscript in a few days.

Now, he could basically confirm… that his dream was indeed real, a future world 600 years later.

This also explained the transformation of Keke Cat into Rhine Cat—

The Space-Time Butterfly Effect did indeed exist!

After the two talked for a few more minutes, Lin Xian opened the office door.

Zhao Yingjun was standing outside the door, having waited for a long time:

"Professor Xu, how did your discussion go? Was the matter resolved?"

Xu Yun walked out with a chuckle:

"I was a little out of sorts today, and I apologize for the intrusion."

Zhao Yingjun shook her head, looking at Lin Xian inside the room:

"You're too polite, Professor Xu. Our MX company welcomes you at any time. I'll arrange for someone to take you back to the university in a moment, and leave you with my business card and Lin Xian's business card. If you need anything in the future, just contact us directly."

"Okay, okay, thank you. I drove here myself."

Xu Yun nodded in agreement, picking up his briefcase and hurrying to leave.

But after thinking it over…

He had barged in so recklessly, and now he was leaving in such a flustered manner, which felt somewhat impolite.

He also thought that since he had already promised Lin Xian, it wouldn't hurt to mention it to his boss here, which would also be a favor to Lin Xian.

Xu Yun turned around and looked at Zhao Yingjun:

"Ms. Zhao, I already mentioned this to Lin Xian earlier."

"Actually, I have indeed received a lot of help from Lin Xian during this period. I have also been very fortunate in my research and have made significant breakthroughs. So I am considering…"

"If one day, my research can truly achieve a qualitative breakthrough, then the concerns I told you about before will disappear. It won't matter even if that failed chemical substance is sold."

"For Lin Xian's sake… I will give your company priority. I will discuss the specific details with Lin Xian at that time."

Zhao Yingjun was slightly surprised. This was an unexpected reversal.

She glanced at Lin Xian, her eyes full of doubt.

But she quickly recovered and returned a smile to Professor Xu Yun:

"That's wonderful, Professor Xu Yun. It would be an honor for our MX company to receive your authorization. We sincerely wish you success in your research soon!"

…

Lin Xian and Zhao Yingjun escorted Xu Yun to the parking lot and watched him leave.

After the car turned a corner, Zhao Yingjun chuckled. She turned her head, looking at Lin Xian with a rather amused expression:

"How did you convince him?"

"I didn't say anything." Lin Xian replied casually:

"I just gave him a few words of advice."

"Gave him a few words of advice?"

Zhao Yingjun chuckled:

"Does Professor Xu Yun look like someone who listens to advice?"

Lin Xian scratched the back of his head.

He looked up at the warm winter sun in the sky:

"People change, don't they?"

"What doesn't change in this world? People's hearts, society, the present, history, the future… everything changes. Nothing is immutable."

Zhao Yingjun was silent.

She nodded in agreement:

"You have a point, but you're wrong about one thing."

A gust of wind blew, stirring up the fallen leaves on the ground.

"History does not change."

Zhao Yingjun said, lowering her head:

"The victor is always right; it is a foregone conclusion."

Her black coat swayed in the wind as she turned and walked towards the company building:

"History will never change."

Whoosh…

The winter wind was dry and sharp, blowing the fallen leaves and trash on the ground into a swirling vortex.

Zhao Yingjun walked away with the click of her high heels, disappearing around the corner of the parking lot.

Lin Xian silently watched her leave…

"History will change."

He muttered, looking at the vortex of leaves on the ground.

Lin Xian naturally knew that the history Zhao Yingjun was talking about was not the same history he was talking about.

The history Zhao Yingjun was referring to was the history before 2022 today.

While the history Lin Xian saw was the history between 2022 and 2624.

Now that the Space-Time Butterfly Effect had been confirmed to exist, then for the future world 600 years later in his dream…

"I am history."
