At five in the morning, Artoria woke up in the study.
She had been asleep hunched over the keyboard for three hours. The screen was still on, displaying a 3D model of the Dimensional Resonance Energy Core. The morning light rose from the sea, passing through the floor-to-ceiling windows and casting pale golden spots on her cheeks and the keyboard.
She sat up straight, her neck stiff. After rolling her shoulders, her gaze fell back to the screen. After a night of calculations, the model was 70% complete. But the remaining 30% was critical—the pattern design of the energy flow channels.
These patterns weren't decorative; they were mathematical structures that guided high-dimensional energy to exist stably in three-dimensional space. The curvature of every arc, the angle of every intersection, and the topological relationship of every node affected energy conversion efficiency. A design error could range from being ineffective to triggering a catastrophic loss of energy control.
She needed calculation tools. However, ordinary CAD software couldn't handle such complex designs involving non-Euclidean geometry.
"System," she whispered, "is there any calculation assistance?"
The interface expanded, and a line of text appeared:
[You can consume one Today's Captured Image opportunity in exchange for 'Precision Calculation Assistance' service, lasting 6 hours.]
The price was significant, but it was worth it.
She nodded. "Use it."
Instantly, a massive stream of data flooded her mind. Those complex geometric relationships, energy equations, and topological constraints became clear and solvable. Her fingers flew across the keyboard, modifying model parameters, optimizing pattern designs, and verifying the stability of the energy flow.
For six hours, she didn't leave her chair. When the assistance effect ended, the complete design for the energy core was displayed on the screen.
It was a sphere eight centimeters in diameter. The outer shell consisted of twelve nested layers of thin titanium alloy shells, with each layer's surface etched with precise patterns. These patterns formed complex interference designs between the different layers. The center of the sphere was a vacuum cavity used to contain high-dimensional energy leakage points.
"It can be manufactured now," she said softly.
But manufacturing required special processes. The precision assembly of multi-layered nested shells, the etching of nanometer-scale patterns, the sealing of the vacuum cavity... with her current equipment, it was nearly impossible.
She walked to the basement. In the morning light, the complete titanium alloy skeleton stood quietly, waiting for its heart. She lightly stroked the cold metal surface, then walked to the workbench and looked at the precision tools.
Not enough. Far from enough.
Her phone vibrated. It was Tony.
"Morning. I thought of a new idea last night regarding your energy core—" Tony's voice stopped. "You sound exhausted."
"Pulled an all-nighter," Artoria told the truth.
"Any progress on the design?"
"It's finished. But there are difficulties in manufacturing."
"Send it over for me to look at. Just the non-confidential parts."
Artoria hesitated for three seconds before sending a 3D view of the outer shell structure—excluding the internal patterns and energy flow design.
Thirty seconds of silence.
"This structure..." Tony's voice carried a rare seriousness. "Multi-layered nesting, shell thickness of only 0.1 millimeters, layer gaps of 0.01 millimeters. And you need surface treatment? This precision requires an electron beam lithography machine. I have one in my lab, but it's used for making chips."
"I need to borrow the equipment."
"Sure. But you have to come to my lab to operate it; the equipment can't be moved. And..." Tony paused. "This design looks a bit familiar, like some kind of... fractal antenna array. Are you making an energy collector?"
"Something like that," Artoria didn't deny it.
"Alright. When are you coming?"
"This afternoon."
"I'll be waiting."
Hanging up, Artoria walked to the terrace. The sea was calm, and the morning light was brilliant. But her thoughts were not calm—going to Tony's lab meant deeper technical exposure, but if she didn't go, the energy core couldn't be built.
"It's worth the risk," she whispered to herself.
She spent the morning continuing to optimize design details. At noon, she had a simple meal and then changed into outdoor clothes—a simple white shirt and dark trousers, tying her blonde hair into a neat ponytail.
At two in the afternoon, she set off on her electric scooter. Tony's Villa was three kilometers away, a ten-minute ride along the coastal road. The smart gate recognized her face and slid open automatically.
Tony was waiting for her in the garage. It had been converted into an open laboratory, filled with a dazzling array of equipment. On the central workbench, the electron beam lithography machine was already preheated, emitting a low hum.
"The equipment is ready." Tony pointed at the lithography machine. "I've set the base parameters, but the specifics depend on your design. Let's see the full blueprints first?"
Artoria handed over an encrypted USB drive. Tony plugged it into the computer and pulled up the full 3D model. When he saw those complex patterns, his eyes widened visibly.
"This is..." He zoomed in on a section. "Surface projections of non-Euclidean geometry? The curvature changes of these patterns follow some kind of... manifold law?"
"Energy guidance channels," Artoria explained. "The shape of the patterns determines the direction of the energy flow."
"Where did you learn this?" Tony turned to look at her, his expression one of pure technical curiosity. "This isn't a traditional engineering approach; this is more like... applied mathematics of high-dimensional physics."
"My own research," Artoria repeated the answer.
Tony stared at her for a few seconds and then nodded. "Fine. Manufacture first, questions later."
For the next three hours, the two worked in front of the lithography machine. Tony handled the equipment operation and parameter fine-tuning, while Artoria was responsible for design verification and real-time corrections. Thin titanium alloy discs were sent into the vacuum chamber, and the electron beam etched nanometer-scale patterns onto the surface, reaching atomic-level precision.
When the first piece was finished, Tony carefully took it out and placed it under an electron microscope. On the screen, the patterns were clearly presented, with every arc perfectly replicating the design.
"Beautiful," Tony praised. "This kind of precision is enough for making chips. How many layers are you planning?"
"Twelve layers."
"That requires twelve lithographies, and every time you'll need to reposition and realign. The accumulated error will be huge."
"I have an alignment plan." Artoria pulled up the assembly design—each thin shell had special positioning markers, achieving nanometer-level alignment through optical interference.
Tony quickly scanned the plan and nodded. "Feasible. But you'll need a high-precision assembly station. I have one next door."
Work continued. At six in the evening, they had completed the manufacturing and pre-assembly of the first three layers. When the three thin shells were precisely stacked on the vacuum suction stage and the patterns formed a perfect interference design under the optical microscope, Tony let out a long breath.
"This level of craftsmanship is enough to publish three papers in 'Nature'," he said. "Are you sure this is just a personal project?"
"I'm sure." Artoria carefully placed the semi-finished product into a special container.
"Alright, I won't ask." Tony wiped the sweat from his forehead. "Continue the rest tomorrow? Let's stop here for today. I've had the chef prepare dinner."
Dinner was at the open-air restaurant on the top floor of the Villa. The setting sun dyed the sea golden-red, and in the distance, Artoria's small house looked like a tiny speck in the twilight.
"That thing in the deep sea," Tony said suddenly while cutting his steak, "S.H.I.E.L.D. contacted me today. They want to organize a joint research team. I refused."
"Why?"
"Because of bureaucracy." Tony took a sip of red wine. "They want to lock that thing in a lab and study it in slices. But I think... it's an intelligent entity and should be respected. You spoke with it last night, didn't you?"
Artoria looked up.
"My cameras caught it," Tony admitted. "You drew patterns, and it responded. Although I don't know the content, it was a conversation. S.H.I.E.L.D. caught it too, but all they see is a 'potential threat.' That's the difference."
"What do you think it is?"
"I don't know." Tony looked at the sea. "But it's definitely not a monster. It has intelligence, logic, and is trying to communicate. Maybe... it's a visitor. A visitor from somewhere else."
Artoria remained silent. Tony's intuition was very accurate.
After dinner, it was already dark. Tony walked her to the door. "Continue tomorrow?"
"Continue."
"Alright. I'll keep the equipment preheated, so come whenever you're ready." He paused. "Also, watch out for S.H.I.E.L.D. Their first reaction to the 'unknown' is always control. They won't just let your contact with that thing go."
"I know."
On the way back, the sea breeze was cold. Artoria rode her electric scooter, her mind replaying today's manufacturing process, Tony's words, and the conversation with the luminous entity from the previous night.
When she got home, it was completely dark. She placed the semi-finished energy core into the shockproof box in the basement and then walked onto the terrace.
The sea was pitch black tonight, with no light.
But she could feel it—the luminous entity was nearby. It was observing, waiting.
She went back to the study and turned on the computer. On the screen was the design for the energy core. She suddenly had an idea.
Pulling up the design software, she added a new set of patterns to the innermost layer of the core—not energy guidance patterns, but information patterns. A set of simple information encoded based on the geometric language the luminous entity had shown her last night:
"Thank you. This is the heart. For a partner."
The patterns were tiny, hidden among the complex energy patterns, unnoticeable unless one looked closely. This was a whisper between her and the luminous entity, hidden inside the heart of the future robot.
Late at night, she finished the modifications. Just as she was about to rest, her wristband vibrated.
It wasn't an alert, but rhythmic short vibrations—three times, pause, twice, pause, once. This was the "non-emergency communication" signal she had agreed upon with Coulson.
She picked up. "What is it?"
"Miss Artoria, we've monitored special activity from the luminous entity near your coast." Coulson's voice was calm. "It seems to be... deploying something. We haven't detected any threat, but we'd like you to confirm."
"I'll take a look."
She walked to the terrace. Under the sea, the luminous entity appeared again. But this time it wasn't hovering; it was moving, slowly swimming along the coastline, leaving a trail of tiny points of light behind it.
The points of light arranged themselves into a complex array on the seabed, then slowly sank into the sand, their glow fading until they finally disappeared.
Having finished all this, the luminous entity turned toward the small house, its light flashing three times before it sank into the deep sea.
Artoria went back inside and contacted Coulson. "It's deploying some kind of device. It's not a threat."
"Are you sure?"
"I'm sure. It's... helping."
"Helping?" Coulson's tone was doubtful.
"Helping me monitor the coast. Those points of light are a sensor array, monitoring energy fluctuations and spatial anomalies," Artoria explained, which was her intuitive understanding.
There was a long silence on the other end of the line.
"Understood. We will continue to observe. Goodnight, Miss Artoria."
"Goodnight."
The call ended. Artoria stood in the basement, looking at the skeleton, at the semi-finished core in the shockproof box, and out the window at the coast where the unknown array had just been deployed.
The luminous entity was helping her. In its own way.
She walked to the workbench, opened her notebook, and wrote on the latest page:
"Progress: Core manufacturing started. Tony is providing equipment support but is not involved in the core design. The luminous entity has deployed a coastal monitoring array, intending to protect or observe. S.H.I.E.L.D. remains vigilant but has not interfered."
"Tomorrow's goals: Finish manufacturing the remaining nine layers of the core. Attempt to establish a clearer communication protocol with the luminous entity. Continue the design of the skeleton's transmission system."
Finishing her notes, she closed the notebook. It was late, but she wasn't sleepy.
Walking to the skeleton, she whispered, "Your heart is in the making. Your protector is in place. Soon, very soon."
The skeleton remained silent. But in the morning light, a faint reflection gleamed on the titanium alloy surface, as if in response.
Outside, the sea was calm. But in its depths, the points of light slept quietly in the sand, guarding this coast, guarding this creation, and guarding the upcoming new life.
