After successfully escaping, Jin Zhan inevitably had a feeling of being in a different world. Every muscle in the body seemed to be desperately gasping for the fresh air after escaping death.

The scene he had just discovered appeared in front of his eyes, and the fragility and ugliness of human nature at the moment of crisis made him feel a chill that was even more terrifying than a laser ray that could cut off himself instantly.

He rested quietly in this space for a long time, but he did not completely get rid of the feeling of loss.

At this time, a surprised female voice came from her ear: "Jin Zhan, thank God." It's a miracle that you managed to get out safely. ”

Jin Zhan looked back and found that it was Natasha, who was alone, shouting to herself with joy on her face.

Jin Zhan saw that there were still fellow trialists looking for him, and when he saw the warm winter sun, his heavy mood recovered slightly. Forced to laugh: "Maybe God sympathizes with a fool like me." ”

"Nope! Jin Zhan, you are a companion worthy of respect. You see, Providence doesn't want you to die on this act of saving people, does it? Natasha comforted Jin Zhan quite gently and considerately.

Jin Zhan's depression eased for a moment, and then he sighed again: "Thank you Natasha, but now unfortunately this space seems to have evolved into a battle royale, and even the trialists kill each other, could it be that the horror created by this space for us is such a Shura purgatory?" Can only the strong get a USB drive and leave this space? ”

When Jin Zhan asked him like this, Natasha's expression changed again and again. But in the end, it was calm, and there was nothing to say.

Although Jin Zhan's continuous dodge and escape operation ensured that he was unharmed, it did consume a lot of mental strength and physical energy. He had to rest and recover in this room for the time being.

Since the space had no water or food so far, he was already experiencing some fatigue.

Although they only rely on the central nervous system to interact after entering this dream world, due to the all-round simulation design of this dream world system, their body's needs for food and water will also be simulated as much as possible.

If there is a lack of food and water, the system will stimulate their central nervous system with a special electric current, objectively weakening their physical energy and simulating the intuitive experience of hunger and thirst.

So for both of them, time is also a chronic poison.

Jin Zhan slowly began to compile the markers and relative positions of each room recorded by his brain in his own brain during his rest.

After learning about the structure of the hypercube, he completely abandoned the original 3D modeling method and began to try to build a complex 4D hypercube space model in his brain.

The different three-dimensional spaces in the four-dimensional space model are repeatedly overlapped, distorted, and connected. Jin Zhan must always overcome his brain's concept and understanding of the three-dimensional space of reality.

Purely through the concept of mathematics to assist in the construction of the simulation model of the whole space. Make good use of the marked space and the connection between them to continuously deduce its relative coordinates in the four dimensions.

At the same time, it is necessary to completely abandon the thinking mode of normal people, and forcibly separate the cognitive model in the brain into a separate computing unit to control a three-dimensional space. Then, the three-dimensional space controlled by each thinking module is organically connected to maintain a strange vertical relationship with each other.

This rebellious thinking project is not easy to say, even Jin Zhan, who has a high degree of brain potential, can't help but hit walls everywhere, and it is difficult to move forward, and it is impossible to achieve it overnight.

After failing again and again, Jin Zhan had no choice but to return to the original point and adopt a step-by-step, step-by-step ascension method.

Starting from a simple two-dimensional model to a three-dimensional model, he carried out a lot of projection thinking training and surface calculation in his highly matrixed thinking by means of spherical projection and surface projection with mathematical tools such as Riemannian geometry.

Combine countless scrolling, angle-shifting 2D orthogonal projections with perspective projections to create an actual 3D model. And through a large amount of data and training results, a computational model of surface projection is gradually established in the brain.

The establishment of this projection reduction calculation model allows Jin Zhan to finally get a first glimpse of the door of the four-dimensional space, using countless three-dimensional space slices or three-dimensional membranes as projections to deeply restore the unfathomable four-dimensional mysteries!!

With the gradual deepening of derivation and construction, Jin Zhan simulated a combination of intertwined and unintelligible spaces in his brain.

The concept of three-dimensional distance and size no longer exists, and from all directions, he can see the superimposed objects and each section in space!

At the same time, he himself seemed to be inside himself! The space has no concept of interior and exterior. A small space turned into a chaotic collection, and at any time there was a sense of fear beyond cognition.

"Between square inches, there is a bottomless abyss!!" After a long time, Jin Zhan suddenly opened his eyes and exclaimed.

Natasha was recuperating from the sidelines, and when Jin Zhan's inexplicable words came out, Natasha's eyes suddenly lit up, and she hurriedly ran up and asked, "How is it now?" Have you rested well? What's the catch? ”

Jin Zhan opened his eyes and said with a wry smile: "It's just that I have gained a piece of chaos." But I don't think we're going to get lost anymore, and I've probably sorted out all the spaces we've walked through. ”

Natasha couldn't help but be overjoyed when she heard this, although she had no idea how Jin Zhan did it. In Jin Zhan's narration, her understanding of the four-dimensional space can only stay in the conceptual sense, but it is obviously not important.

She couldn't hide her excitement and said, "Great, does it mean that we can find that USB drive before others?" After all, I think we've all been running around like headless flies, walking through a lot of repetitive places. ”

"At least we should have a little bit of an advantage." Jin Zhan replied flatly, and at the same time secretly praised the reaction of the woman in front of him in his heart, which can be described as very alert.

"That's great, but there's still a question, how do we avoid the thugs out there? I think it's very likely, as you just said, most people now understand it as a battle royale for the USB game. Natasha asked excitedly but worriedly.

"This is really troublesome, and according to the previous combing of the room organs, I have also roughly summarized the distribution law of the dangerous space. It has a clear correspondence with the coordinate values on the W axis of the four-dimensional cube. ”

"In this way, we can basically save time to test whether there is a mechanism in the space. The goal of our exploration is the remaining safe room, which has a clear advantage over the others. ”

"Even if we accidentally meet, I can quickly plan a safe retreat route." Jin Zhan explained confidently.

Natasha is now completely uninterested in trying to understand Jin Zhan's argumentation process and reasoning basis. The oriental man in front of her had eyes as deep as the sea, but they were crystal clear, and he gave her an extremely reliable good impression for no reason. And he seems to have some kind of expertise in reasoning and calculation.

So she said with her trademark softness and a little sexy smile on the corner of her mouth: "Then it's up to you, if you have a good rest, let's hurry up and set off." ”

"Okay." Jin Zhan rubbed his temples, briefly explained the cooperation of the next two people, and then continued to race against time to start the task of finding the USB drive.
