Scholar's Advanced Technological System
chapter-1406

As a three-dimensional creature, it was almost impossible to cross the barrier of a high-dimensional world.

Just like how two-dimensional creatures couldn't perceive the existence of a three-dimensional world, if they didn't rely on scientific theories or special technical means, all they could observe was the projection of three-dimensional objects on paper with the help of light sources. The laws of physics were incomprehensible to two-dimensional creatures.

It was almost impossible to stand in the position of low-dimensional creatures and interact with high-dimensional space.

The four-dimensional space fragment and the existence of Z particles were somewhat similar.

But its existence was more complicated.

It was not a thing that existed in four-dimensional space; it was the space itself.

Therefore, it was theoretically impossible to cross this barrier.

It was impossible for any physical force to have any effect on it. Even if a nuclear bomb was brought to the ruins, it would not have any effect.

However, this didn't mean that Lu Zhou couldn't do anything.

The internal space of the entire ruins was divided into countless small pieces by the fragments of the four-dimensional space. All of the channels here were continuous in a topological sense. As for the change in position, it was caused by the interference of the four-dimensional space fragments in the three-dimensional space, which made these tunnels mix together like a jigsaw puzzle.

The reason why he couldn't cross the barrier in front of him was only that the "door" was not there. The inaccessible space in front of him was like a piece of the jigsaw puzzle that was missing.

All he had to do now was to find the missing piece from the thousands of puzzles.

And where it belonged.

If Xiao Ai were here, it would save him a lot of time. But he could only rely on himself now.

Fortunately, since he was level 10 in mathematics, this was not difficult.

Half an hour passed.

Lu Zhou finally found the missing piece of the puzzle. His eyes were fixed on the screen. Finally, a smile appeared on his face.

"I didn't expect the answer to be close by…"

Lu Zhou tapped on the wrist-mounted computer on his left arm. He reopened the communication module.

"See you soon."

He turned and left the spacious grotto. He left the tall arch and returned to the place where he was before.

Without any hesitation, Lu Zhou, who already had the answer in his mind, walked through the dusty tunnels in the opposite direction.

Soon, he came to a bottomless cliff and stopped at the edge of the cliff.

If his inference was correct, this should be the place where the piece of the puzzle was pulled out. The inaccessible space he saw in the grotto originally belonged to this place.

And if he wanted to enter there, he could only go through this "door"!

The voice seemed to have been observing his every move. The voice once again reappeared in his ear.

"Are you ready?"

Lu Zhou, who was about to take a step forward, stopped.

"What does that mean?"

"I'm saying, it's not too late to leave now."

Lu Zhou suddenly smiled and said in a joking tone.

"Do you want me to leave?"

"I don't want anything. The Observers keep me busy; they will always send suitable individuals to me."

Lu Zhou: "If it doesn't matter, why should you persuade me otherwise?"

"Because the road ahead is not easy. I'm just providing you with an alternative. If you leave, you can live a happy and stable life."

There was a bewitching tone in the voice.

Lu Zhou admitted that this sounded really tempting.

He stood at the top of the academic world, the pinnacle of power. Even if he did nothing, he would be able to live the rest of his life happily. There was no need to let himself take such a big risk.

However…

"You are right, but since I'm already here…" After thinking about it, Lu Zhou continued, "It would be a shame for me to leave."

"Too much curiosity is not a good thing."

Lu Zhou smiled and said, "Really? Now I know you're not an Observer."

"Oh, why?"

Lu Zhou: "Because I remember that person said that curiosity is an enviable quality."

"It's your decision. But you have to think clearly. Once you make a choice, you can't look back."

"I've already made up my mind before I came here."

Lu Zhou closed his eyes and pondered for a long time. He then silently took off the wrist computer on his left arm and threw it on the open space behind him.

He took a deep breath and used all his courage to leap into the abyss. He let gravity pull himself toward the endless darkness.

His fall lasted for about four seconds.

Then, something magical happened!

The moment he was swallowed by the boundless darkness, a feeling of inertia crawled through every cell in his body.

It was almost like the direction of gravity had been reversed in an instant. A huge force grabbed his shoulders and slammed it onto the solid ground.

"Ouch…"

Lu Zhou felt like his chest was hit by a truck. He panted loudly and climbed up from the ground.

When he raised his head, there was a hint of ecstasy in his eyes.

The space in front of him was exactly the grotto that he left before. He was on the other side of the "wall".

Lu Zhou contained the excitement in his heart. He took a deep breath and calmed himself down.

"Did I pass all the tests?"

"Sort of."

"What do you mean?"

The voice did not give an answer.

Lu Zhou was confused about what to do next. The surrounding space suddenly lit up with a soft light. A crystal that was as flawless and transparent as diamonds appeared in front of him out of thin air.

There were tiny lines printed on the clear and transparent surface. Those lines were like projections of the ruins, corresponding to each tunnel.

Lu Zhou was curious about this magical phenomenon. He was about to reach out to touch it when he was stopped by the voice in his ears.

"Don't touch it with your hands!"

Lu Zhou's hand stopped. He put his hand away and stared at the flawless and transparent spherical crystal for a long time. He finally spoke.

"Don't touch it with my hands… Should I touch it with something else?"

"This is the fragment of the four-dimensional space. All changes in the ruins are caused by it."

Lu Zhou couldn't help but wonder. He then asked, "How did you fold the four-dimensional space fragment into such a… perfect state?"

"This is not our technology." The voice said lightly, "Folding the fragments of four-dimensional space into a three-dimensional sphere can only be done by The Observers."

Lu Zhou: "This is what the Void intends to give me? A piece of four-dimensional space?"

"No, it's just a key."

"Key?"

"Yes, it can lead you to the treasure."
