CC's attitude surprised Lin Xian.

This was probably the best, most patient, and easiest to communicate she had ever been with him in all their interactions.

Perhaps it had something to do with the events that had transpired between them.

The previous times they had met, they were either enemies, harboring ulterior motives, or simply bickering; it was difficult to have such a calm opportunity for conversation.

But this time, their identities were different.

They were united by a common goal.

Even though they ultimately failed to open the safe, they genuinely gained CC's trust.

That's why she was willing to exchange information with him, which was unheard of.

"Okay, I'll go first."

Lin Xian leaned against the unheated safe and slowly told CC about the Lin Xian he knew…

Which was basically his own self-introduction.

Starting from his graduation from university and talking about his usual work, it was just like attending a job interview.

But he had only just finished a small portion—

"Alright, you don't need to tell me anymore."

CC interrupted him, shaking her head:

"The Lin Xian you know is definitely not the same person as the owner of this safe."

"Why?"

Lin Xian didn't understand.

He himself had suspected this before, wondering if this wasn't his safe at all.

But suspicion was suspicion... he still had a glimmer of hope in his heart.

What if this safe was deposited by him in 2032, or even 2042? Logically, that was possible.

Because his current year, 2022, hadn't reached the point where he would deposit the safe, so naturally, he wouldn't know the password.

But he didn't expect CC to directly conclude that this Lin Xian was not that Lin Xian, and couldn't be him.

"Because… he's too ordinary."

CC sighed:

"Actually, I don't know what the real Lin Xian should be like. I don't even know any Lin Xian, but I have a feeling... it's definitely not the ordinary Lin Xian you know."

"Alright."

Lin Xian spread his hands:

"Since you don't want to listen, I won't tell you then. Now it's your turn to answer my questions, right?"

CC nodded and also leaned against the safe:

"I don't even know where to start. Ever since I was little, my memories have been very chaotic."

"I can't describe the feeling, it's like there are many memories in my mind that don't belong to me, but are also the life I experienced. It's like… the life of another me in another world."

"Is it a dream?" Lin Xian asked.

CC shook her head:

"It's not a dream, I'm very sure of that. Although these memories are also fragmented and blurry, just some discontinuous, trivial fragments, I'm sure it's not a dream."

"Is it a parallel universe kind of feeling?" Lin Xian asked again.

CC was silent, nodding in agreement:

"I'm not sure either. In short, it's a very difficult feeling to explain. I've seen doctors, and they say it's a delusion, possibly a mental personality split."

"But those fragmented memories... are just too real. It's hard for me to imagine that they're just fictional fantasies. That's why I want to prove it."

She turned and pointed to the safe with Lin Xian's name on it:

"In those fragmented memories, there's a middle-aged man I'm sure I've never met and definitely don't know, with long, messy hair and an exaggerated beard."

Middle-aged man?

Long hair?

Big beard?

The image of a wild, strange uncle appeared in Lin Xian's mind.

"In the memory fragment, that person told me that he left something for me in this safe. He said—"

*Click!*

A crisp sound of a circuit connecting.

*Whoop! Whoop! Whoop! Whoop!*

An ear-piercing alarm sounded all around!

"Crap, the main circuit is back on, automatic alarm!"

Da Lian Mao, who had also been listening intently, jumped up as if he had been electrocuted:

"We have to run quickly!"

CC nimbly stood up, picked up her mask, and turned to leave.

"Don't, don't, don't!"

Lin Xian hated cliffhangers the most, and hurriedly grabbed CC:

"Finish it! Finish it before you run! It won't make a difference!"

CC turned back to look at Lin Xian:

"That person said, 'If you want to know all the past and the truth, then open that safe.'"

"In the memory fragment, he originally intended to tell me the password, but I don't know why he didn't say it in the end. I'm not sure if it's because the memory fragment is incomplete."

*Whoop! Whoop! Whoop! Whoop!*

Amidst the alarm, CC shook off Lin Xian's hand and turned around:

"Ah, there's one more thing."

She turned back again, smiling for the first time.

Her eyebrows and eyes seemed to bloom like pear blossoms.

Her eyes curved into adorable crescents, with two faint dimples at the corners of her mouth:

"That man's voice sounds a lot like yours."

"That's why I was willing to cooperate with you today, otherwise... I wouldn't have come with you at all."

*Boom!!!!!!*

*Boom!!!!!!*

*Boom!!!!!!*

The scorching white light arrived on time.

Incinerating everything in sight.

…

…

*Clang, clang…*

The biting cold wind beat against the windows.

In the corner of the bedroom, on the bed, Lin Xian opened his eyes.

He lifted the quilt, sat up on the bed, and recalled what CC had said in his dream just now.

Although he didn't open the safe this time in his dream...

But he gained a lot in other areas.

He put on his slippers and got up.

Lin Xian came to the desk and turned on the lamp:

"This time in the dream, I gained a lot of information, I must sort out my thoughts properly."

He picked up a pen.

While the memories in the dream were still fresh, Lin Xian wrote down his gains on white paper one by one:

【1. The changes in space-time are uncontrollable.】

Although this point was simple and easy to understand, and there was no need to write it down specifically, Lin Xian had indeed suffered a loss once.

He always thought that his use of future resources to change reality and rewrite the future would always only benefit him and make the future develop in a better direction.

But the fact is not the case.

"The changes in the future are uncontrollable... it is very likely that I will try to outsmart someone but end up losing out, and ultimately lift a stone to drop it on my own feet."

He deeply remembered this lesson.

In the future, when he tries to change reality and rewrite the future, he must consider and weigh the pros and cons more carefully.

【2. When do space-time changes occur? A point of no return is needed.】

Lin Xian understood why the new hafnium alloy and the hibernation capsule filling liquid were both achievements of Professor Xu Yun, but only the new hafnium alloy caused a space-time butterfly effect, while the hibernation capsule filling liquid did not.

The reason lies in a very simple concept—

"Spilled water can never be recovered."

Professor Xu Yun had already sent the sample and data of the new hafnium alloy to the Dragon Kingdom Aerospace Research Institute.

Then, from this time anchor point onwards, no one can stop this product from flowing to all walks of life in the world.

Even if the Dragon Kingdom Aerospace Research Institute decides to monopolize it, in this 600-year river of time, this material will inevitably leak and be transferred from aerospace to civilian use.

So from this time node, the new hafnium alloy has become "spilled water", destined to be unrecoverable, so space-time changes occurred as scheduled.

But the hibernation capsule filling liquid is different.

Now this research result has not been published and is still in a "Schrödinger's state". Only Professor Xu Yun has the original paper, and there are many situations that can prevent its public release.

Even Lin Xian himself can say a few words in front of Professor Xu Yun and persuade him to change this method of publication. Lin Xian believed that Xu Yun would listen to some of his opinions, if he insisted.

After all... Xu Yun did ask for his opinion, and Xu Yun still respects him in this regard.

What's more, Xu Yun's paper has not yet been finalized, and everything is subject to change.

So from the current point of view, the water of the hibernation capsule filling liquid has not yet been spilled, and there is still the possibility of being rewritten, so it has not caused space-time changes.

"Space-time changes require a point of no return... interesting, I thought it would be a real-time change."

Lin Xian inexplicably felt that there should be other rules, laws, and the like in the details of space-time changes.

【3. CC has memories in her mind that do not belong to her.】

This is currently difficult to explain.

But Lin Xian had also experienced the same dream confusion, so he could understand it to some extent.

He was not sure whether CC really had delusions, mental personality splits... her memories were incomplete, just some fragmented and discontinuous fragments.

And it was precisely to prove whether this was a delusion or a real memory that CC risked opening the safe.

"This... is quite similar to my previous behavior of verifying dreams, all for the sake of getting a truth, an answer."

【4. The voice of the middle-aged man with long hair and a beard in CC's memory fragment sounds a lot like mine.】

This piece of information is very important.

"No wonder CC didn't kill me many times before, and had a sense of trust in me... Sure enough, it was because of the voice that made her a little curious about me."

Lin Xian nodded.

This clarifies the previous doubts.

CC really doesn't know me and hasn't seen me.

But my voice sounds a lot like the man in her memory fragment, so her attitude towards me is not so normal.

However, Lin Xian was sure that the strange uncle could not be him.

"First of all, it is impossible for me to live to be 600 years old."

"Secondly, there are many people who sound alike, and I even think her voice sounds familiar. Plus, CC's memory fragments may not be reliable."

"Finally, and most decisively—"

Lin Xian touched his clean-shaven chin, his brow furrowed slightly:

"It is absolutely impossible for me to have long hair and a beard..."

"Absolutely impossible."
