Chapter 50: Four-Dimensional Space, Past and Future

  "Go back to the past, or arrive in the future!?" Wang Yi and others stared at me in shock.

  "Ah." I nodded, suddenly thinking of a post I had read before, and gave an example: "For instance, if it only takes one minute to fall asleep, then what we can accomplish in a day would be equivalent to 1440 days under normal circumstances. What if it only took one second to fall asleep? Then we could accomplish in one day what normally takes 86,400 days! By the same token, if our work speed approached the speed of light, our lifespan would be virtually infinite, which is what many people are striving for - longevity!!!"

  "Then according to what you said before, aren't we already in a four-dimensional space now!? We can all live forever!?" the young man asked again.

  Shaking his head, "I was just saying that if the Penrose stairs really exist, they can only exist in four-dimensional space. I didn't say this is a miniature four-dimensional space. And even if you can live forever inside a four-dimensional space, you can't stay there all the time, you have to come out eventually, and then there's no such thing as living forever."

  "Besides, didn't you guys think it was a ghost hiding before? Now that I think about it, this explanation is more acceptable. After all... if it's really a ghost hiding, we might still have a chance to escape, but if we're unlucky and entered the fourth dimension, then we'd be completely out of luck!"

  The last sentence I didn't say out loud, I don't want to crush their confidence, nor do I want to despair myself, and after all, this is just an inference, isn't it? Maybe it's just a ghost covering up, four-dimensional world or something, let's just think about it as usual.

  "Even if this isn't a four-dimensional space, how can we get in?"

  "Really? Does that mean immortality?" A glint of desire flashed in everyone's eyes, and I furrowed my brow, explaining objectively: "Adding time to the three dimensions makes it four-dimensional space. Normally, we say we are in three-dimensional space because of the irreversibility of time. However, if you can control time, then you've entered."

  "What if we, who are in a three-dimensional world, enter a four-dimensional space, what will we see?"

  Seeing them getting more and more excited, I had to look at Xian Xian for help, it's none of my business, really none of my business, I just mentioned a Penrose staircase, how did things suddenly get pulled into four-dimensional space?!

  Xian Xian hooked up the corner of her mouth and revealed a wicked smile, and finally, she also gave me a "good luck to you" look, meaning that you have to solve the trouble you caused yourself!

  He gave him a disdainful look, "When I first mentioned this matter, why didn't you stop me? Instead, you even participated enthusiastically, which led to the current situation that can't be taken back."

  "Although I admit that our boss is quite handsome, can't you, a grown man, stop exchanging flirtatious glances with him right under our noses? Can you quickly answer that question?" Although I knew they were just teasing me on purpose, I couldn't help but roll my eyes and said: "What else can you see? Can't you guys just go online and search for it yourselves?"

  "Big brother, are you fooling us again?" Wang Yi immediately became dissatisfied, and others also echoed: "Want to search? You need a network for that! It's just a small joke, don't bother introducing yourself to Wang Yi, the big blockhead."

  "Yes, yes, don't be on familiar terms with me." Wang Yi scratched his head and smiled with a foolish expression, but the greedy desire in his eyes did not diminish at all, instead it became even more intense.

  I knew that once they started talking about the issue of "longevity", even a slight chance of longevity, they would never let it go easily. Moreover, I'm not that kind of petty person. After adjusting my thoughts, I continued: "If you enter the four-dimensional space, even if it's the most tightly sealed safe, you can still see all the contents from one 'side'. Not only that, but you can also see how every single screw is coupled inside!"

  "You can see your own muscles, your own skeleton, and the blood flowing through the vessels as if you were dissected. However, it's strange that although the blood is flowing right in front of your eyes, it won't spill out. All walls in the world are just an illusion to you, because if you want to, you can completely bypass them from another 'side'!"

  "This is simply too amazing!"

  Looking at their shocked and delighted faces, eager to rush into the four-dimensional space immediately, I had to strike them down mercilessly, lest they get overly excited and develop delusions of grandeur. With a wicked smile, I said: "Of course, all this is relative, and even the scientific community can't perceive the existence of four-dimensional space at present. Moreover, don't forget that we are in a three-dimensional world; even if there really is a four-dimensional space, it should exist within the universe, right? So, if you truly want to enter it, first board a manned spacecraft and soar into outer space! I believe that with your willpower, one day your dreams will come true!"

  "Haha...” Xianxian suddenly chuckled softly beside him, stood up from the stairs, patted the nonexistent dust on his butt, and slowly said: “Fengzi is right, you can think about four-dimensional space in your mind, don't take it seriously. You've stolen many Dou, what strange things haven't you encountered? Instead of daydreaming here, why not hurry up and find a way out.”

  After Xian said that, everyone's faces fell. Originally excited and enthusiastic, they suddenly became disheartened. But this doesn't seem to be my problem, does it?

  "And you." Xianxian looked at me lightly, with a smile still hanging on the corner of her mouth, but in the bottom of her eyes, it seemed like there was no smile, instead, there was an additional layer of emotion that I couldn't understand.

  I can only innocently look at Xianxian, please ignore me, I'm just a person responsible for answering questions...

  "I wonder if this wall can be knocked down!?"

  "Just try it and you'll know!"

  "Good grief." As soon as the words left his mouth, a sharp impact sound and a dull echo rang in my ears, making my eardrums tingle. Turning my head, I saw Wang Yi holding a sharp hoe with a look of entanglement and disappointment staring at the wall.

  Although the light is not very sufficient, along his line of sight, I still clearly see that there is no sign of fragmentation on the wall. The force of Wang Yi's previous move must be extremely heavy, and it can be heard from the sound. However, this wall did not even have a crack, which is quite impressive!

  "It's getting late, everyone should rest first. I and Fengzi will take the first night watch, others follow the old rules." Xianxian ordered without leaving any room for doubt, and everyone nodded in agreement, starting to tidy up their sleeping places. Although the stairs were narrow, it was still better than not resting at all. Besides, they had just eaten their fill while talking, so it was indeed time to sleep.
