58: Chapter 58 The Non-Euclidean Legacy

There was neither light nor darkness inside the tunnel; these two concepts lost their meaning here.

The consciousness of Lin Shen and Sarah perceived a multi-dimensional topological structure—space was like a sheet of paper folded, twisted, and knotted countless times, while time was like threads wrapped around the paper, taut in some places and slack in others.

The sensors of the kuafu-2 were in complete chaos.

The optical cameras saw a shattered kaleidoscope, radar echoes traveled back and forth millions of times within a few nanoseconds, and the gravity meter's needle spun wildly.

Only through the direct perception of the consciousness of Lin Shen and Sarah could the spacecraft maintain a basic sense of direction.

"The flow of time is uneven," the Sarah part reported, her mathematical intuition thriving here.

"Time on the port side is about 37 times faster than on the starboard side. If we maintain our current orientation for ten seconds, the port side components will age by three months."

The Lin Shen part immediately adjusted the spacecraft's orientation to balance the time gradient.

"Can the navigation array still work?"

"Quantum entanglement is still effective within the tunnel, but the signal is experiencing fractal delays," Nuwa's voice was intermittent, like an old radio.

"I am trying... to recalibrate... but physical constants have slight variations in local areas."

The spacecraft cautiously pushed forward.

The tunnel was not a straight passage but a series of interconnected Klein bottle and Möbius strip structures.

Sometimes they were clearly flying forward, only to suddenly appear behind; other times, a part of the spacecraft entered another dimension, and the instruments showed the ship's length constantly changing.

The technology of the builders had left a clear mark here.

Glowing symbols occasionally appeared on the tunnel walls, not carved, but interference patterns formed by the curvature of space itself.

The Sarah part could read these symbols—they were the basic vocabulary of the language of the builders, describing the fundamental constants of the universe: the speed of light, the Planck constant, the fine-structure constant...

But some symbols were flickering, like indicator lights with a poor connection.

"These constants are unstable here," the Lin Shen part analyzed the data.

"Look at the fine-structure constant in this area; it is 0.3% larger than the standard value. This means electromagnetic interactions here are stronger, atoms are smaller, and chemical bonds are tighter."

"The laws of physics have been modified," the Sarah part felt shocked.

"the builders can not only manipulate space-time but also locally rewrite the laws of nature. This is at least... the capability of a Type 3.0 civilization."

The spacecraft continued to go deeper.

As they advanced, the tunnel structure became increasingly complex.

They began to see other traces left by the builders: in some areas, space was folded into complex sculptures, like the visualization of mathematical formulas; in some, time flows were woven into loops, where the past and future intersected.

At a particularly wide node, they saw the first complete message from the builders.

It was not text or an image, but an immersive experience.

When the spacecraft passed through the area, the consciousness of Lin Shen and Sarah was forcibly connected to a simulated reality—a fragment of the final moments of the civilization of the builders eight million years ago.

Scene: An infinitely extending white hall.

There were no walls in the hall, only countless layers of nested planes, and on each layer stood—or rather, existed—individuals of the builders.

They were not human, nor were they any known life form.

Each individual was a complex structure of light and shadow, with a rotating polyhedron at the core, surrounded by constantly evolving mathematical symbols.

They were engaged in a debate.

There was no sound, only the direct exchange of thoughts, but the consciousness of Lin Shen and Sarah could understand.

One individual (labeled "Preservationist") was stating:

[The heat death of the universe is inevitable. All order will eventually dissipate. Our responsibility is not to resist in vain, but to preserve the essence. Convert the civilization into information structures and sow them into young star systems to ensure the fire of intelligence never goes out.]

Another individual ("Resister") retorted:

[Preservation is surrender. The essence of intelligence is to explore the unknown. If we give up now, it proves that intelligence itself cannot transcend the laws of physics. We must attempt the impossible: reverse entropy and create eternal order.]

A third individual ("Compromiser") proposed:

[We can do both. One part will convert into the Sower System to preserve existing knowledge; the other part will continue to research the ultimate solution. But we need time—far more time than the remaining lifespan of the universe.]

The "Resister" responded:

[Then create time. Or create a domain unaffected by time. We are already close...]

The debate continued.

The consciousness of Lin Shen and Sarah could see the technology displayed by the builders: they could create miniature universes, pause local time, and reverse the entropy of a single galaxy.

But all of this was just a drop in the bucket for the ultimate fate of the entire universe.

In the end, the "Preservationist" won a narrow majority.

Not because they were more persuasive, but because the "Resister" could not provide a feasible ultimate solution.

The decision was made: the civilization of the builders would convert entirely into the Sower System.

But before the conversion, they would leave this tunnel—a testing ground, a legacy repository, an information bottle for those who come later.

If a future civilization could reach a sufficient level and understand their predicament, perhaps they could find the answer they failed to find.

The conversion process began.

One by one, the individuals of the builders turned into pure light and merged into a massive structure—the core of the Sower System.

But just as the conversion reached 87%, an accident occurred.

A portion of the individuals from the "Resister" faction refused to convert.

They escaped, taking with them some unfinished research and technology, and disappeared into the unknown regions of the universe.

These escapees were later known as The Exiles, and the technological fragments they left behind might be the origin of the Gardener Civilization.

The simulation ended.

The consciousness of Lin Shen and Sarah returned to the spacecraft, unable to calm down for a long time.

"So the Sower System is a product of compromise," the Lin Shen part summarized, "and the Gardener originated from those 'The Exiles' who refused to compromise."

The Sarah part added, "But the technology of 'The Exiles' is incomplete, and their thinking may have been twisted as a result. The Gardener's so-called 'pruning' and 'archiving' might be a distorted continuation—they still want to 'preserve the essence,' but their methods have become extreme."

Nuwa's voice suddenly became clear: "Large-scale structure detected ahead. Energy readings... indescribable. It exists in multiple dimensions simultaneously."

The spacecraft slowly sailed out of the main part of the tunnel and entered a vast space.

The laws of physics here were entirely defined by the builders: gravity pointed in all directions, light traveled along fractal paths, and time flowed through space like liquid.

And in the center of the space, an object was floating.

It looked like a simple geometric shape: a regular dodecahedron with side lengths of about one kilometer.

But upon closer inspection, it could be seen that each of its faces was displaying a different reality: one face showed the birth of stars, one the evolution of life, one the rise and fall of civilizations, one the derivation of mathematical formulas... twelve faces, twelve simulations of fundamental cosmic processes.

"This is the core of the 'builders legacy'," the Sarah part felt the excitement of the node consciousness.

"A complete civilization database, containing all their knowledge, history, art, philosophy... and their unfinished research."

A line of symbols appeared on the surface of the regular dodecahedron.

The Sarah part translated: "'Those who come later, you have passed the preliminary test. But to gain full access, you must prove that you understand our deepest regret.'"

"What regret?" asked the Lin Shen part.

The symbols changed, showing a new question:

[If we had the chance to do it all over again, should we choose a different path?]

There were three options below the question:

A. Yes. Resistance is the essence of intelligence.

B. No. Preservation was already the best choice.

C. Refuse to answer. Every civilization must choose for itself.

But the consciousness of Lin Shen and Sarah knew that this was not a multiple-choice question.

They had to provide their own answer and prove that this answer came from a true understanding of the situation of the builders.

In the merged mode, they began to analyze.

First, they needed to understand what the true regret of the builders was.

From the previous simulation, it seemed their regret was not in choosing to preserve, but in being forced to choose preservation without finding a better solution.

They regretted that intelligence ultimately could not overcome the laws of physics, and that the universe gave them the ability to think but not the tools to change their ultimate fate.

So, if they could do it over, what would they do?

The consciousness of Lin Shen and Sarah retrieved all known data: the design of the Sower System, the distortion of the Gardener, the struggle of human civilization, and everything seen inside the tunnel.

They tried to simulate the results of different choices.

Simulation 1: the builders fully supported the "Resister" faction, investing all resources into the research of an ultimate solution.

Result: Before the civilization perished, they made a breakthrough and discovered a possible method to reverse entropy, but did not have the time to implement it.

Simulation 2: the builders converted entirely into the Sower System, leaving no individuals to continue research.

Result: The Sower System stagnated, the civilization stopped evolving, and it was eventually threatened by distorted products like the Gardener.

Simulation 3: A compromise plan, but with different allocation—90% converted, 10% continued research.

Result: Insufficient research power, slow progress, and likely failure in the end.

It seemed there was no perfect answer.

But the consciousness of Lin Shen and Sarah suddenly realized that perhaps the question itself was the problem.

The thinking mode of the builders was purely rational; they tried to use optimal solution thinking to solve a problem that might not have an optimal solution.

But the value of intelligent life might not lie in finding the ultimate answer, but in the process of constantly asking questions.

The Sarah part remembered the words of the pacific node: "The universe is a conversation."

The Lin Shen part remembered the essence of the technology tree system: not to provide answers, but to show possible paths.

They gave the answer:

[The meaning of intelligence does not lie in overcoming fate, but in understanding fate; it does not lie in finding answers, but in always asking questions. You do not need to do it over, because you have already completed the most important task: you passed the question on. Now, the question is in our hands. We will continue to search for the answer and continue to pass the question on. This is the meaning of civilization—a relay race across time and space.]

The answer was encoded into a high-dimensional mathematical proof and injected into the regular dodecahedron.

The dodecahedron began to rotate.

The realities on each face began to merge and evolve, showing new possibilities: the Sower System collaborating with new civilizations on research, The Exiles returning and bringing new perspectives, different civilizations facing the ultimate question together...

The rotation stopped.

The regular dodecahedron opened a door—not a physical door, but a data interface.

[Answer accepted.] A gentle voice sounded directly in their consciousness, different from the mechanical feel of the watcher, this voice was full of emotion, like a kind elder, [You have understood. Preservation is important, but passing it on is even more important. Now, the legacy is yours.]

Massive amounts of data began to transmit.

Not through electromagnetic waves or quantum signals, but written directly into the thinking structure of the consciousness of Lin Shen and Sarah.

This was the essence of the eight-million-year civilization of the builders: from fundamental physics to ultimate mathematics, from life design to the principles of consciousness, from artistic creation to ethics and philosophy...

But there was a specially marked section in the data stream: "Unfinished Research: 137 Possible Paths for Entropy Reversal".

The Sarah part immediately began to analyze these paths.

Most required a civilization of level 2.5 or above to implement, but three paths could be started at a level 1.5 technology level.

The key to one of these paths was the graviton crystal—it could stabilize the space-time structure and provide a foundation for reversing local entropy.

"We found it," the Lin Shen part said excitedly, "Not only did we find the material, but we also found the method to use it."

The data transmission lasted for three subjective days—objective time had only passed seventeen minutes.

When the transmission ended, the regular dodecahedron began to become transparent, eventually dissipating into space.

"The legacy has been passed on," the voice said finally, "The tunnel will close in twenty-four hours. May you go further than we did on the road to finding the answer."

The spacecraft began its return journey.

This time, the tunnel seemed much friendlier, and the twisted structures automatically opened the straightest path for the spacecraft.

Nuwa reported: "Latest news from Earth. Quantum network shutdown progress: 67%. The energy reading of the Avenger Node has dropped to 85% of the restart threshold, but it has started to accelerate preparations—it seems to have detected our success. The restart countdown has been adjusted to: 240 days."

"What about the Gardener?" asked the Lin Shen part.

"The deep space monitoring network has detected three gardener probes accelerating toward the Solar System. Estimated arrival time: 180 days. Their target might be the tunnel, or it might be Earth."

Time was tighter.

But they now had the complete technology database of the builders, the possible paths to reverse entropy, and the capital to stop the Avenger Node and deal with the Gardener.

When the spacecraft rushed out of the tunnel entrance, the consciousness of Lin Shen and Sarah actively dissolved the deep fusion, restoring them to two independent but closely connected consciousnesses: Lin Shen and Sarah.

The experience of fusion had changed them—they could sense each other's thoughts at any time, could instantly share memories and understanding, but still maintained their independent selves.

"We succeeded." Sarah looked at the graviton crystal synthesis formula virtually displayed in her hand, "Now, we have to build a factory on Earth within 240 days that can stably produce this material, and design a plan to stop the Avenger Node."

Lin Shen pulled up the planetary defense system blueprint from the builders database: "And a plan to deal with the gardener probes. These probes are very likely here to evaluate the consequences of the tunnel opening. If we can demonstrate sufficiently powerful defensive capabilities, they might delay a full-scale invasion."

The kuafu-2 adjusted its course and returned to Earth at full speed. Travel time: 26 days.

On Earth, Max received their brief communication: "The legacy has been obtained. Hold on, we are coming back with the answer."

The orderly shutdown of the quantum network was still ongoing globally, but the three core nodes were maintaining minimal operations.

Civilizational regression had already begun: some high-precision factories relying on quantum computing had shut down, the global logistics system was in chaos, but basic life support systems were still working.

And the Avenger Node, after detecting the energy fluctuations within the tunnel, broadcasted a new message:

[High-level contamination source detected approaching. Purification protocol priority increased. Restart preparations accelerated.]

Its surface began to release more energy tentacles, reaching deep into the Earth's crust, preparing to trigger a global geological restructuring.

The countdown continued: 240 days.

The gardener probes were accelerating: 180 days.

Lin Shen and Sarah were returning: 26 days.

Human civilization stood on the edge of a cliff, but for the first time, it held true hope in its hands—a legacy from an ancient civilization from eight million years ago, and a draft of an answer on how to face the ultimate fate.

Behind the spacecraft, the tunnel entrance slowly closed and disappeared into the starry sky.

Ahead, Earth was waiting.
