Actually, it wasn't difficult to get Chu Anqing's hair.

Living together day and night, there were plenty of opportunities. But since he happened to see it today, a thief never leaves empty-handed, so Lin Xian just took it.

He found a small plastic bag for storing small parts, about half the size of a bank card, and put a few strands of Chu Anqing's hair into the bag.

He pinched the top with both hands, and with a *zip*—he sealed the bag, locking a few strands of brown hair inside.

Lin Xian pinched a corner of the square plastic bag and shook it:

"I have a lot of things waiting for me. Each one I finish is one less thing to think about later."

He had a sudden whim, looking at the electronic alarm clock vv:

"If we eventually find Zhang Yuqian's grave and successfully dig up the bones… ahem, DNA, and then compare it with Chu Anqing's hair, and find that the DNA is completely identical, exactly the same..."

"If such a result really appears, what does that mean? Chu Shanhe and Su Xiuying, and that elderly couple, are clearly two completely different sets of parents, so no matter what, it's impossible for them to give birth to two daughters with completely identical DNA. That's too ridiculous, no one would even write it that way."

The electronic alarm clock vv nodded with an emoji:

"The logic is sound... but the fact that Zhang Yuqian and Chu Anqing look exactly alike is also a fact. In this world, no matter how outrageous anything is, in short, existence is its own justification. As long as those things can objectively exist in this time and space, this universe, then they are justified, and allowed within the rules."

"According to my current understanding and knowledge, I think Zhang Yuqian's DNA and Chu Anqing's can't be the same. That's inexplicable in any scientific field. But the fact that two people look exactly alike, from a probabilistic point of view, is entirely possible. The reason I suggested you go dig up the grave is entirely because you said that in the dream world 600 years later, there's also a girl named CC who looks just like them… This must be taken seriously."

"Speaking of which, the girl CC hasn't appeared in your dreams for a long time, has she? Does she still exist? Could she be Chu Anqing or Zhang Yuqian under certain circumstances? Don't ask me why, I'm just guessing, because… it seems like that's the only thing that makes sense."

Lin Xian opened his suitcase.

He took out the casual clothes he had brought, put the plastic bag containing Chu Anqing's hair into the inner pocket of his shirt, and then zipped it up:

"As for CC, I really haven't seen her for a long time. I haven't seen her in the entire Third Dream. But that's because there's no Taym Bank in Donghai City or Rhein Sky City in the Third Dream."

"Without the bank, there's no hafnium alloy safe, so what would she do there? She said she was born in Brooklyn, USA… I don't know if the Third or Fourth Dream has this place, but in short, she has absolutely no reason to come to Donghai. She only has eyes for the safe. Where the safe is, she is—"

Suddenly.

Lin Xian realized something!

"Wait a minute."

He stood up, rubbed the stubble on his chin, and paced around the dormitory:

"I suddenly thought of something incredible. In the previous Fourth Dream, because there was no Taym Bank, there was naturally no safe with my name on it. So… regardless of whether CC actually exists, she couldn't possibly appear around my 'spawn point'."

"But! Now there is Taym Bank in the Fourth Dream, so the safe with my name on it must be in the bank. With this change, the missing part of CC's history has been corrected to its original state. That is to say, CC will still look for the safe with my name on it because of what the bearded man in her memory fragments said, trying to open the safe by cracking the password."

"Do you understand what I mean, vv? That is to say… in the world of the current Fourth Dream, if the Fourth Dream is real, then I will definitely be able to see CC again. She's a girl who would give her life for the safe, she would dare to steal the safe in a hail of bullets, so this time she definitely won't be able to resist it, she will definitely come—"

"CC, right now, is in Donghai City in the Fourth Dream!"

vv thought carefully for 2 seconds and said coldly:

"There are many loopholes in your idea. First of all, even if you see CC, it doesn't necessarily prove that your Fourth Dream is real. It might eliminate the possibility of a film set and actors; but it still can't rule out the possibility that your Fourth Dream is a virtual world."

"The virtual world they constructed for you is August 28, 2624, but who knows what the real future world outside has already reached? Others could use the events that happened on August 28, 2624, in every corner of the city as a blueprint to build a simulated world for you."

"What's more, even if your Fourth Dream world is real, why would CC have to go to Taym Bank to rob the safe on this particular day? She's so obsessed with the safe, she would have tried to steal it long ago. It doesn't necessarily have to wait until this day. Conversely, it's also possible that she's still on an ocean liner from Brooklyn to Donghai on this day. The probability of you meeting her on the day you enter the dream is extremely low."

"No, no, no."

Lin Xian waved his hand:

"The most crucial point, I didn't tell you. CC has memory fragments from other timelines in her head. Since she has the memory fragments of robbing the bank with me in the First Dream; then she must have the memory fragments of invading New Donghai City with me in the Second Dream."

"In the Second Dream, our revolutionary friendship was very deep. If she really has the memories of the Second Dream, she will definitely try to find me."

"In the Second Dream, I told CC almost everything, including my special abilities, the ability to infinitely loop the same day, and that the safe might be related to me, and that Taym Bank would be established at the end of 2023… I told her everything at that time, and she knew everything."

"She didn't completely trust me at the time, after all, that was only the first time we met in the Second Dream, and CC was skeptical of what I said. However, if CC can simultaneously have the memories of the First Dream and the Second Dream about me in the Fourth Dream, then after comparing them, she will naturally understand that everything I said at the beginning was the truth and that I didn't lie to her at all."

"Without me, CC would never be able to crack that safe. Since Taym Bank can still celebrate its 600th anniversary so ostentatiously, it means that the bank's security and reputation are fine and that there should have been no theft or intrusion incidents."

"Therefore, if CC in the Fourth Dream wants to crack the safe password, she will definitely try to find me. She knows clearly that I have more methods than her, that I really have the ability to infinitely loop the same day, and that I am more likely to crack the safe password than her."

"And, most importantly. The enemies in the future world do not have the ability to extract memories. We have already verified this. So even if they can create a fake CC in a virtual world, at most they can only replicate a CC who robs Taym Bank, they can only copy CC's behavior, but they cannot copy CC's memories."

"This is what the enemies 600 years later would never expect or guess—"

"They originally thought that my sudden time travel to the world 600 years later would inevitably mean that I wouldn't know anyone, that I wouldn't have any acquaintances. But they never expected that before I met CC, CC already had memories of me in her mind! And there were many of them, a full two dreams' worth of memory fragments!"

"I never thought that the key to breaking the situation was actually CC."

"If the CC in the Fourth Dream knows me and can accurately say things from the First Dream and the Second Dream, then it is enough to prove that my dream is real!"

Lin Xian's thoughts instantly became clear.

So...

So CC is the real space-time beacon!

The memory fragments in her mind are more reliable than the hafnium alloy safe! Even if he beat the brains out of that mysterious old man… he would never have imagined that in a time and space 600 years apart, he and CC were already long-time friends.

Therefore.

As long as he can meet CC in the Fourth Dream and match the memories and code words, then nothing else needs to be considered.

He can directly determine that the dream world must be real!

"It's really a case of man proposes, God disposes..."

Lin Xian said with emotion:

"I've been thinking about it for so long, and I didn't expect the real answer to be on CC."

"But, Lin Xian..."

The electronic alarm clock vv said:

"This CC you're talking about, her physique that can preserve memory fragments from other timelines is indeed a good breakthrough point. The enemy can't possibly realize this. I also agree that if you can really talk to CC, you can instantly confirm the authenticity of the dream."

"But the problem is... don't forget, you are surrounded by dozens of soldiers in the Fourth Dream, armed to the teeth, and you will be stunned and taken away in less than half a minute. Even if CC is standing outside the encirclement, you won't have enough time to communicate with her. She, a girl, can't be like the Monkey King, stepping on auspicious clouds to break into the enemy's lair and kill everyone, and then rescue you, right?"

Lin Xian chuckled:

"It's not necessarily impossible."

"CC is still a very magical girl. She's not an ordinary girl. She's very brave, very strong, has many ideas, is very indifferent but is very serious in her heart, and is very smart."

Memories brewed into a wind, rising out of thin air.

Lin Xian recalled the woman wearing the Ultraman mask, blowing up the head of Big Face Cat with one shot;

Recalled her disguising as Li Ningning, stepping on the face-helping human pillar to climb over the high wall of the garbage dump;

Recalled her disregarding the danger to her life, cracking the security door password at the last moment when she was discovered by the drone;

Recalled her cutting the throat of the city inspection officer with a wave of her hand, crouching down and coldly and quickly wiping out the bank guard.

She is a password expert.

She crossed the ocean alone to Donghai.

She is careful and good at collecting information.

She always gives people surprises, Dora CC.

"She's not an ordinary girl."

Lin Xian repeated again, turning his head to look at the electronic alarm clock vv:

"You haven't met CC, so you don't understand her. There seems to be infinite potential in this girl. If she really intends to find me and save me, she will definitely find a way. Or, we can also think about it from this aspect to see if there is any way to leave a hint for CC 600 years later, so that she can come to my birthplace to save me on the day of Taym Bank's 600th anniversary celebration."

"You really trust this girl named CC." vv said lightly.

"It's okay."

Lin Xian chuckled:

"I still have a good impression of her, although I don't really like her personality, but I don't really hate it that much. I used to be with her almost every night, so I'm very familiar with her. And obviously, she and that bearded man, who is probably me in the future, have a deep relationship, and she is indeed a trustworthy person."

"Even if we put aside trust, CC, who has the previous memory fragments, also knows very well that I and her are grasshoppers on the same rope. After trying so many times and failing to open the safe, CC can naturally understand that if she wants to open the safe, she can't do without me; and if I want to break out of the encirclement of soldiers, I can't do without CC. This time… the two of us are really bound together."

…

vv was silent.

It was unusually quiet.

"What's wrong?"

Lin Xian felt something was wrong:

"Is there an error in my analysis?"

"Sigh…"

The electronic alarm clock vv sighed:

"Little princess's rival… has increased again."

"…"

Lin Xian took a deep breath, recalling the scene of violently disassembling the trash can robot, and forcibly suppressed the urge:

"Don't forget to continue monitoring Jask, and that US X-37B space plane running on the high-altitude orbit."

After saying that, he didn't bother to pay attention to the artificial idiot.

He lifted the quilt and got in.

Sleep.

…

The next day.

Lin Xian and Chu Anqing were doing practical exercises in the space plane, familiarizing themselves with the various equipment in the equipment cabin.

*Da da da da da* A series of rapid high heels sounds came.

Huang Que led Liu Feng onto the boarding frame and entered the space plane, arriving at the equipment cabin with a solemn expression.

"Lin Xian, the space-time particle has already flown past the moon's orbit and entered the Earth-Moon space, and its speed has inexplicably, and in a way that defies Newton's laws, decelerated, and the speed has immediately dropped to about Mach 3."

"If we estimate based on this speed, this space-time particle will enter the atmosphere's exosphere at a height of 1,000 kilometers on March 27th. I have already reported the accurate time to Huang Que."

March 27th…

Even though they had been mentally prepared for this period of time, when they actually heard the accurate arrival date of the space-time particle, Lin Xian and Chu Anqing looked at each other, and they couldn't help but feel a little nervous.

Raising his watch, Lin Xian looked at today's date, knowing it was there.

March 20th.

He raised his head, looking at the top of the space plane's cabin, looking through the dome of the hangar filled with bright white lights, looking through the Karman line 100 kilometers above sea level, looking through the universe space with a pitch-black background.

The distance to truly seeing that space-time particle that has traveled across time and space and come from afar…

There are 7 days left!
