Nana's voice rang out in the living room at three in the morning: "The signal repeats three times, with precise intervals, and the frequency matches that of the Wind Cave."

Chen Hao sat up abruptly, his neck cracking. Ignoring the pain, he reached for the tablet, "Play it again."

Susan leaned over from the other end of the sofa, her hair askew, "Isn't it natural disturbance?"

“No.” Nana pulled up a waveform graph, and three almost overlapping curves appeared in the air. “This is coded transmission, it’s regular and purposeful.”

Carl stared at the timestamp at the edge of the screen. "It...sent it on its own?"

“Yes.” Nana nodded. “The signal received by the C-7 monitoring station points to the surface rift valley area. The energy peak occurred six hours ago, which matches our predicted energy outlet location.”

Chen Hao grinned. "So, our model was a lucky guess?"

“It’s not a guess.” Karl ran his finger across the data stream. “There’s a logical chain. Vibration cycles, thermal anomalies, mineral distribution—it all connects.”

Susan slammed her hand on the table. "Then it's not a hypothesis, it's evidence!"

None of the four mentioned sleeping. Nana had already retrieved all the data from the past 72 hours of C-7 and started performing spectral overlay analysis. On the screen, ripples gradually converged into a clear rhythm, like a heartbeat, or perhaps a whisper.

“A slight thermal anomaly occurs every twelve hours,” Nana said. “After three rounds, a complete signal is released. The next one is expected in sixty-three hours.”

"Just enough for us to prepare." Chen Hao rubbed his face. "This time, we not only need to listen for the voices, but we also need to get the items."

"What should I take?" Susan asked.

“Samples,” he said. “Go to the rift valley, mine the minerals, capture the crystal reactions, and photograph the entire chain in real life.”

Carl frowned. "But we don't have the equipment for on-site exploration, nor do we have the necessary permits."

“No need.” Nana turned on the star map projection. “The National Astronomical Observatories’ unmanned inspection vehicle routinely scans this area every Tuesday. The next mission will take place right during the energy eruption window.”

"You're planning to hack in?" Chen Hao raised an eyebrow.

“No need,” Nana said calmly. “The inspection vehicle will automatically upload the raw data. As long as we connect at the receiving end, we can obtain first-hand information.”

"Isn't this against the rules?" Susan asked softly.

"It's borderline," Chen Hao laughed. "But it's better than nothing. Besides, we didn't steal missile blueprints; we just glanced at a planet and let out a fart."

Susan chuckled, "That's a really disgusting analogy."

"Science knows no distinction between highbrow and lowbrow," Chen Hao said, shrugging. "The key is that we can finally produce something real."

The three divided the work among themselves. Susan contacted the plant sample bank to retrieve all records related to the blue crystals, focusing on comparing their fluorescence changes at different energy bands. Carl re-ran the model, adding new data and optimizing the prediction accuracy, especially the warning time before the eruption. Chen Hao was responsible for integrating the report framework and clearly outlining the logical chain: from signal capture to mechanism deduction, and then to its practical significance.

Nana wasn't idle. While processing data simultaneously, she also used a knowledge base to search for the current state of Earth's technology. Several hours later, she suddenly looked up: "Match found."

"Huh?" Chen Hao was biting into his bread.

"The energy conduction properties of resonant blue crystals," she said, "If they can be successfully synthesized artificially, they could be used to improve the sensitivity of quantum sensors, potentially increasing it by more than three times compared to current technological limits."

The room was silent for a second.

"Three times?" Karl's eyes widened. "The most advanced technology right now only has a resolution of 0.5 nanometers. If we triple that, wouldn't we be able to see electron orbits directly?"

“Theoretically, yes,” Nana said. “In the past three years, seven papers in the materials science community have raised similar needs, but there has always been a lack of suitable media. Our discovery fills that gap.”

Susan stood up excitedly, "That means it works! It's not metaphysics, it's not fantasy, it's something that can really change the course of technology!"

“Then we should definitely release it.” Chen Hao wiped the bread crumbs from his mouth. “But we can’t release it haphazardly. We’ll only publish the phenomena and data, no exaggeration, no guarantees.”

"What if people say we're faking it?" Susan calmed down again. "After all, we haven't even touched the actual product."

“Then let them verify it.” Chen Hao opened the document. “I’ve attached the original waveform, heatmap, and model parameters. Reproduction is welcome worldwide. Anyone interested can calculate it themselves.”

Carl nodded,
