52: Chapter 52 The Vanguard's Gaze

Seven hours after the Gardener reconnaissance unit, the "Geometric Eye," entered the asteroid belt, it stopped moving.

It hovered near the orbit of Ceres, about 450 million kilometers from Earth.

Its perfect icosahedral structure rotated slowly, with no visible thruster plumes on its surface, as if it completely ignored the law of conservation of momentum.

All telescopes in the deep space monitoring network were aimed at it, but the images returned were blurry except for its geometric shape—its surface seemed to absorb electromagnetic waves of all wavelengths, reflecting back only informationless darkness.

"It is observing." Nuwa analyzed the limited telemetry data. "It has emitted seven active scanning pulses, each lasting 0.3 seconds, with an interval of exactly 23 seconds."

The scanning range covers all planets from Mercury to Neptune, but the main energy is focused on Earth and the Moon."

"Scanning content?" Lin Shen stood before the main console of the Dragon Kingdom's control center, his eyes simultaneously displaying global evacuation progress, spaceship design progress, and the real-time data stream of the "Geometric Eye."

"Cannot be fully parsed. But based on the modulation method of the pulses, it at least includes: geological structure analysis, biosphere energy flux assessment, civilization activity heatmaps, and... quantum information field intensity measurement."

The last item made everyone in the control center nervous.

"Quantum information field?" Academician Li Weimin asked, "What is that?"

"A theoretical concept." Sarah's voice connected via the quantum channel; she was still at the Imperial Space Center, but her consciousness could handle multiple tasks simultaneously. "Advanced civilizations transmit information through quantum entanglement networks, leaving faint 'imprints' in spacetime."

"The Gardener might be detecting traces of our interaction with the Sower System, assessing the 'level of contamination'."

On the holographic screen, the scanning data of the "Geometric Eye" was visualized.

A complex network diagram emerged on the Earth's surface: red areas were densely populated cities, blue was ocean circulation, and green were biodiversity hotspots.

And above these conventional layers, there was another almost invisible purple halo—that represented the quantum information field intensity.

The halo was particularly obvious in several locations: Xichang of the Dragon Kingdom, the Imperial Space Center, the Mariana Trench (although the node had self-destructed, residual signals remained), and... this control center where Lin Shen was located.

"They can locate us." General Liu's voice was low.

"More than that." Sarah pulled up another set of data. "The scanning pulses contain a mathematical instruction set. Nuwa, play the effect of the raw signal converted into sound waves."

A sound came from the control center's speakers: not a melody, not a language, but a pure mathematical rhythm.

Every 0.3 seconds, a fundamental tone sounded, then complex harmonics were derived, with each harmonic's frequency being the golden ratio of the previous one.

This sound made people instinctively feel uneasy—it was too perfect, so perfect that it lost all the randomness of life.

"This is their 'self-introduction'." Sarah explained. "Expressing the beauty of mathematics through sound, showcasing their form of existence."

"But at the same time... this is also a probe. Different civilizations will have different physiological reactions to this sound. They are collecting our stress response data."

Sure enough, the global biological monitoring network reported that in all areas where this sound was recorded, human brainwaves showed similar pattern changes: increased prefrontal cortex activity, suppressed amygdala activity—this was confusion and awe when facing extreme rationality.

"They are testing whether we are 'rational enough'." Lin Shen understood. "The Gardener Civilization believes that only thoroughly rationalized existences are worth preserving."

"Emotions, randomness, non-logical behavior... these are flaws in their eyes."

"Then we might fail." Max's voice interjected. "Humanity is full of irrationality."

"But that is also why we survived." Lin Shen said. "Nuwa, prepare a response. In the way we define 'beauty'."

Three hours later, the Dragon Kingdom's "Sky Eye" radio telescope array adjusted its direction.

This was not an attack, but an artistic expression.

Lin Shen had Nuwa integrate the most representative sounds of human civilization: Bach's fugues, Dragon Kingdom's guqin performances, African drumbeats, bird calls, the rustling of wind through forests, and a baby's first cry.

All these sounds were encoded into electromagnetic waves and beamed toward the "Geometric Eye."

The signal traveled at the speed of light and arrived four hours later.

For the next 23 seconds, the entire Solar System seemed to hold its breath.

The "Geometric Eye" stopped rotating. The darkness on its surface began to ripple, like a stone thrown into a calm pool of water.

The ripples gradually formed a pattern—not mathematical symbols, but an image: a snowflake, the crystallization process under a microscope.

"It is responding." Sarah interpreted. "Snowflake crystallization is the mathematical beauty of nature, but every snowflake is unique. It is saying... it understands what we mean. But..."

The image suddenly distorted, changing into another picture: a perfect regular hexagonal snowflake suddenly shattered, turning into countless identical tiny regular hexagons.

"It is saying that diversity will eventually return to unity." Sarah's voice carried a chill. "Uniqueness is only temporary; standardization is eternal."

The communication ended. The "Geometric Eye" began to move again, this time not toward Earth, but toward Mars orbit.

It stopped there and unfolded a new structure: slender tentacles extended from each vertex of the icosahedron, and these tentacles began to collect dust and debris from the asteroid belt.

"What is it building?" Lin Shen stared at the real-time image.

"Or what is it preparing?" Sarah retrieved historical data. "The sower archives record that the Gardener's reconnaissance units sometimes use local materials to build 'assessment devices'."

"That might be a testing platform used to evaluate the target civilization's defensive capabilities."

"Testing?" Max asked. "Like a military exercise?"

"More like a scientific experiment." Sarah said. "They will set a problem and observe how we solve it. Based on the method and efficiency of the solution, they will evaluate our 'potential level'."

Nuwa's simulation results came out: "Based on the collected material composition and energy consumption rate, the device being built may be a 'spacetime maze'—a twisted geometric structure containing space that violates conventional physical laws."

"Passing through the maze requires understanding higher-dimensional geometry, or... using creative thinking to find non-standard solutions."

"The first exam question given to us." Lin Shen understood.

"What's the deadline?" General Liu asked.

"Device construction progress: 12%. Estimated completion time: 30 Earth days." Nuwa replied. "But considering their technology might accelerate, the actual time might be shorter."

Thirty days. Meanwhile, the global coastal evacuation was entering its most difficult phase.

Earth, the coast of the Bay of Bengal.

This was one of the most densely populated delta regions in the world, with over 40 million people living in areas below five meters above sea level.

The abnormal sea level rise had already reached four meters, and with storm surges, the actual threat height exceeded eight meters.

The rescue fleet jointly dispatched by the Dragon Kingdom and the Imperial Space Center was helping with the evacuation, but progress was slow.

"We only have 72 hours!" The on-site commander roared in the communication channel. "At the current speed, we can evacuate at most one-third of the people!"

Satellite images showed dense crowds of people on the coastline moving like ant colonies, but roads were cut off by floods, bridges had collapsed, and there were not enough ships.

Worse still, climate anomalies caused continuous heavy rain in the area, visibility was extremely low, and helicopters could not take off or land.

Lin Shen pulled up the terrain data for the area and thought quickly: "Nuwa, calculate how many resources are needed if we build a temporary levee here?"

"The coastline in this area is 320 kilometers long. To build a levee capable of resisting an eight-meter water level, at least 50 million cubic meters of construction materials are needed. Even if all global engineering forces are mobilized, it will take 15 days."

Too late.

But another thought flashed through his mind. Lin Shen pulled up the technology tree system. Under the [Environmental Engineering] branch, a technology called "Nano Self-Assembly Barrier" was shimmering with a faint light.

Unlock progress: 41%. Prerequisites: Master molecular-level 3D printing; possess sufficient nanomaterial reserves; complete large-scale distributed computing control.

The Dragon Kingdom already had foundations for the first two. The third one... Nuwa could do it.

"Initiate the second phase of the 'Nüwa Mends the Sky' plan," Lin Shen ordered. "Airdrop nano-material dispensers to the Bay of Bengal. Nüwa, you are responsible for coordinating the self-assembly of all nano-units to form a temporary barrier. It must hold for at least seven days to buy time for the evacuation."

"Understood. But I must remind you: our nano-material inventory is only sufficient to cover eighty kilometers of coastline. Furthermore, this is experimental technology and has never been used in large-scale field operations."

"Then let this be its first field operation," Lin Shen said without hesitation.

Three hours later, one hundred and twenty transport aircraft took off from around the globe and dispersed billions of nano-units over the Bay of Bengal. These tiny robots drifted down like dust and began working immediately upon contact with the seawater. They connected with each other to form a mesh structure, then extracted minerals from the seawater to accelerate their own replication and assembly.

Real-time satellite footage showed a silver-gray line beginning to emerge along the coastline. At first, it was only a few centimeters high, but it grew at a speed visible to the naked eye: ten centimeters, one meter, three meters... Seven hours later, a temporary dam, five meters high and stretching for eighty kilometers, appeared along the coastline. Ocean waves crashed against it, their energy absorbed and their impact dispersed by the nano-structure.

"Barrier efficiency: 87%," Nüwa reported. "It is expected to hold for one hundred and sixty-eight hours, exactly seven days."

The voice of the on-site commander came through, sounding excited: "The water level has been contained! Evacuation speed can be tripled!"

But this was just one of dozens of crisis points around the world. Similar situations were unfolding simultaneously in the Yangtze River Delta, the Mississippi River Delta, the Ganges Delta, and the Nile Delta. The Dragon Kingdom's nano-material inventory was quickly exhausted, leaving other regions to rely on traditional methods.

Meanwhile, the construction progress of the Geometric Eye in Mars orbit had already reached 19%.

Imperial Space Center, Sarah's isolation laboratory.

Max watched Sarah through the observation window. She sat in a chair with her eyes closed, but her hands were operating rapidly in the void, as if controlling an invisible console. Her consciousness was connected to the global quantum computing network, handling multiple tasks simultaneously: assisting Nüwa in optimizing the nano-barrier, analyzing the scan data of the Geometric Eye, advancing the design of the interstellar spacecraft... and engaging in some form of dialogue with the node consciousness within her.

"She is overdrawing herself," the medical officer said to Max. "Over the past seventy-two hours, her brain activity level has been three hundred times that of a normal person. We don't know how much longer her body can sustain this."

"Has she said anything?"

"Only one sentence: 'I need to understand them to be able to fight them.'"

At this moment, Sarah suddenly opened her eyes. In those eyes, the rotation speed of the data streams reached an unprecedented level; the pupils were almost invisible, leaving only a sea of flowing light.

"Max," her voice was unnaturally calm, "I have found a possible method. Regarding the spacecraft's propulsion system."

She pulled up a design blueprint. It was not fusion propulsion, nor vacuum zero-point energy, but a hybrid system: installing a 'space-time fold engine' at the rear of the spacecraft to generate thrust by distorting the space behind it. Theoretically, this engine does not need to carry a large amount of propellant, and its efficiency is thousands of times that of fusion propulsion.

"But what materials and technology does it require?" Max asked.

"The core components require a material capable of withstanding extreme space-time curvature. Among the formulas left by the pacific node, there is an alloy: using island-element as the matrix, doped with 'graviton crystals'—a substance that exists only on the surface of neutron stars."

"Then how do we obtain it?"

Sarah pointed to the Sun: "There are trace amounts of graviton crystals in the solar wind. But collecting a sufficient quantity would require... building a collection net with a diameter of one thousand kilometers near the Sun, and operating it for at least ten years."

Another seemingly impossible task.

"Unless..." Sarah's eyes returned to normal, the data streams fading away to reveal her original brown pupils, "unless we find a shortcut. In the memories of the pacific node, there is a coordinate—not a spatial coordinate, but the entry coordinate for a 'quantum tunnel.' Passing through that tunnel leads directly to the vicinity of a young neutron star, where there are large amounts of exposed graviton crystals."

"Where is the tunnel?"

Sarah pulled up the Solar System star map and pointed to a location in the Kuiper Belt: "Here. But the tunnel will only open at a specific time—according to calculations, the next opening is in... eleven months. Duration: seventy-two hours."

Eleven months. Just after the Geometric Eye completes its evaluation device, and before the Gardener army arrives.

"We must go," Sarah said. "This is our only chance to obtain enough material in a short period."

"But how? Our furthest manned spacecraft can only reach Mars."

"Use Kuafu-2," Lin Shen's voice suddenly joined the communication. "Refit it into a manned spacecraft. Although it was originally designed as an unmanned probe, the internal space is sufficient to accommodate two people. If we accelerate the modification, it can be completed within eleven months."

"Who will go?" Max asked.

Sarah looked at Max, then at Lin Shen on the screen: "I will go. I need to go there, not just to collect materials, but also because... the tunnel itself might be a test. The memories of the pacific node suggest that it might be another legacy left by the builders, and only a 'candidate' can pass through safely."

"I'll go with you," Max said immediately.

"No," Sarah shook her head. "This mission requires scientific understanding, not flight experience. And... if the node consciousness within me behaves abnormally in the tunnel, I need one person to remain clear-headed, which the other might not be able to handle."

"Then who will go with you?" Lin Shen asked.

Sarah was silent for a few seconds: "I need someone who can collaborate with me at the quantum level. Someone who can understand high-dimensional mathematics and also maintain a human anchor."

Her gaze fell on Lin Shen.

In the control center, everyone looked at Lin Shen. General Liu wanted to say something but ultimately did not speak.

Lin Shen looked at Sarah's eyes on the screen; those eyes held both the determination of a young girl and the depth of ancient wisdom. He thought of the technology tree system, everything since he woke up, and that phrase 'sower candidate.'

"I will go," he said.

The decision was made within minutes. Over the next eleven months, Lin Shen and Sarah would prepare for this expedition together. Meanwhile, Earth must accomplish three things before they left: first, cope with the evaluation test of the Geometric Eye; second, maintain the survival of civilization amidst climate disasters; and third, prepare defenses for a potential full-scale invasion by the Gardener.

Just as the plan was initially finalized, a new alarm sounded.

The construction progress of the Geometric Eye suddenly accelerated to 47%.

The object it was building in Mars orbit was now clearly visible in outline: it was a giant Rubik's cube composed of countless asteroid fragments, with a side length of about fifty kilometers. Each small cube of the Rubik's cube was rotating independently, forming dazzling combinational changes. And at the center of the cube, a red light point began to flicker, like a heart that was waking up.

Nüwa's emergency analysis indicated that this might not be a simple test device.

It might be a 'civilization evaluator'—once activated, it would emit some kind of field towards Earth, forcing the entire human civilization to solve a cosmic-level problem within a limited time. According to historical data, civilizations that failed the evaluation had a 73% probability of being judged by the Gardener as 'having no value for preservation.'

The countdown was updated again: Estimated completion time for the Geometric Eye evaluation device: fifteen Earth days.

In fifteen days, humanity would face an exam that would determine its fate.

And Lin Shen and Sarah must find the 'reference book' to improve their scores before the exam began.

That reference book was hidden in light signals from eight million years ago, hidden in the quantum tunnel in the Kuiper Belt, and hidden in the human potential that humanity had yet to uncover.

Sarah said one last sentence, which would become the creed for everyone in the days to come:

"The Gardener thinks we are weeds that need to be pruned. But the vitality of weeds lies precisely in the fact that they can grow anywhere and survive in any way. Let them see just how high weeds can grow."

On the screens in the control center, the Geometric Eye Rubik's cube continued to rotate.

Earth's oceans continued to surge.

The human clock ticked toward an unknown dawn.
