Qin Yi estimated that this thing should be the key to opening this stone door, and obviously, something needs to be placed on this dent to open, obviously this has something to do with the things that Zhou Baofa's friend stole from the tomb before, it may be that one of these things is responsible for sealing, one is responsible for opening the door, or it may be the same thing that plays these two roles, in short, without these things, Qin Yi can now be said to be unable to move an inch.

He suddenly regretted that he didn't force the question, but after thinking about it, it was indeed not the best time at that time, even if he forcibly asked something, Zhou Baofa handed over the things to them, and he would not necessarily hand over them all, not to mention that Qin Yi also wanted to know what the use of Zhou Baofa hiding these things was, he didn't believe that he was just trying to make money, after all, now everyone who left this village is dead, Zhou Baofa is not stupid, and he will not exchange his life for money.

As for the affairs of this village, for the sake of safety, Qin Yi and the others also asked other people in the village, what they were afraid of was that Zhou Baofa had concealed the truth in some things, after all, this guy was too strange, and the people around him were infected with that strange disease and died, but he was still alive and well.

If this is a coincidence, then it is not a coincidence that he deliberately concealed what the old couple hid, it is obvious that this guy has a problem, and the problem is very big, and it even involves the problem of the entire copy.

Some people can't be unguarded, even if these people don't seem to have any problems, or even there may be any problems, but often the more such people, the more problematic people are.

……

After solving the problem here, Qin Yi went to find Song Ke, he saw that Song Ke walked from the left passage, so he also entered from the left, planning to see how Song Ke's progress was, he felt that although Song Ke's behavior of going alone to investigate the situation was a bit risky, Song Ke should not take some risks that should not be taken, and he was not too worried about Song Ke.

However, after walking along this passage for a long time, Qin Yi still didn't see any trace of Song Ke, it is said that she should have gone back by now, could it be that the passage on this side can bypass the main tomb and go to the other side of this tomb group?

Qin Yi felt that this kind of thought was very likely, so Song Ke had been gone for so long, she should not have come back early when she found something valuable.

So Qin Yi had no choice but to continue walking, when Song Ke came back, he could also meet her earlier, if this passage could really lead to the other side of this tomb, then he could go out with Song Ke through the exit over there, provided that there was an exit over there.

After walking for a while, Qin Yi felt that something was approaching, and at this time he was still in this passage, which showed how narrow and long this passage was.

"Hmph, just come on." Qin Yi sneered, listening to the voice, there might be more than one thing, he quietly took out the pistol,

But it's not too ordinary, but it's obviously a lazy master, Qin Yi is a little skeptical that he will not cook, if not, then they should change places then, although the conditions of this village are not as bad as the village of the previous copy, but it is too small, and there will be no restaurants.

For Qin Yi's proposal, star fruit was still very happy, and she agreed without much hesitation.

The two chose a mid-range restaurant to eat, star fruit is not particular about eating, and the same is true for Qin Yi, and Qin Yi's main purpose here is to fill his stomach, and star fruit wants to solve the problem.

"Okay, now that the dish hasn't been served, I'll briefly say the content of the brain in the jar first, although you have just seen it, but I have been exposed to it a long time ago, so it is better to think about it first." As soon as Qin said this, he thought for a moment, and soon had an idea.

"It doesn't matter where the story is set, whether it's because of mad scientists or aliens, in short, in order to prove a principle, it doesn't matter." Qin Yiyi, "Suppose you or I ...... Forget it, let's say 'a person', the person's brain is taken out and put in a petri dish, there is a traveling machine that can provide this brain with any information that can simulate his original life, if he wants to move, then this machine will give him the feeling that he has moved, the corresponding pictures and sounds, etc......"

"In short, the environment in which this brain is located makes him think that he is still in his old life, but he does not know that in fact he only has a brain." Qin Yi continued, "What this question asks for is how does this person prove that he is a brain in a vat? ”

"Well, yes, that's pretty much it." Star fruit nodded, "I don't think there's a way to prove it, right?" After all, the information provided to him by the machine can theoretically be infinitely true, and the machine may also provide him with a subconscious ...... not to doubt his own existence."

"So, you already know the answer, and you still want to ask me?" Qin Yi asked rhetorically.

"But I think it's the right answer, and I still want to know if there's a way to crack it." A hint of stubbornness flashed in star fruit's eyes.

"Now that you've thought it's the right answer, there's no chance you'll crack it." Qin Yi smiled, "To be honest, I don't know how to crack it, after all, the conditions for cracking it are very difficult, one is that the person's consciousness is strong enough to realize what his existence is, but if he is really that strong, he will not be taken away from his brain; ”

"Second, he was lucky enough to have some memories of his attack, and then he realized that there was no such thing in this world, and realized that this world might be an illusion......"

"But both of them are a bit unrealistic, it's a paradox, so I don't think there's a way to crack it, and that machine won't give that person these opportunities."

"Okay." Star fruit nodded, a little disappointed.

"Actually, this is a doubt about the existence of people, we can't guarantee that what we are in now is real, such as everything in front of us, all people, although we have memories of these things, but I can't guarantee that you are not an illusion, although I say this a bit excessively, but if you are really an illusion, then it is the same as a human dream, and it is meaningless for me to say some sorry words to you......"

"But I still have to say sorry to you, besides, we may be in a collective hallucination, and the hallucinations we produce are multi-directional and interconnected, and we seem to be eating here now, but in fact, we may be sitting on a grave in the middle of nowhere......"

"Wait, don't go on! I understand what you mean, Brother Qin, your words really benefited me a lot. Star fruit nodded, "But if our existence is really questionable, then does our existence make sense?" So why live? ”
