182: Chapter 182 The Pieces of the Puzzle and the Decisions in the Study

The submissions were varied and full of simple exploratory joy: someone stuck a phone to the heating pipes of an old apartment building to record the faint "blood circulation sound" of the whole building; someone caught the dull rhythm of a train passing by, transmitted through rock like a giant's snoring, in front of the deepest wall of a subway station; someone recorded the faint humming resonance of the building's steel structure itself, triggered by the cheers of the crowd on match day outside a large stadium; some even used homemade seismographs (with a popular science post on the principle going viral at the same time) to try to record the micro-ground vibration waveforms caused by urban traffic...

These submissions might be rough in terms of acoustic expertise, but that curiosity and initiative to "listen to the city's underlying heartbeat" made Alex and the entire operations team feel very encouraged. They specifically opened an interactive page called "City Infrasound Map" on the platform, marking the submissions (after anonymity and artistic processing) at their corresponding geographic locations. Users could click to listen and see the contributor's brief description of the discovery. This map quickly became a fun place to unearth urban legends, attracting more media and public attention.

"It seems we have inadvertently ignited a nationwide, alternative 'urban archaeology'," Marcus said, looking at the backend data and clicking his tongue in wonder.

"Then let's maintain this 'archaeological site' well," Alex instructed. "Invite a few urban planning and acoustic experts to do a few simple popular science livestreams or articles to guide everyone to 'listen' to the city more safely and interestingly. Remember, the core is to stimulate curiosity and a sense of connection, not to turn it into a professional competition."

Taylor's EP creation entered a tight phase. She rearranged Alex's "pressure gradient" as the opening overture of the entire EP, naming it "Diving In." Following that was the complete "deep blue waiting," and then several new songs inspired by "Echo Puzzle" and daily field recordings. The overall concept revolved around "external silence and internal resonance." She even tried using the "emotional resonance" generation algorithm from Emily's voice program to process a recording of rain she had made, resulting in a background track full of random beauty, which she used in one of the songs.

Alex acted as the "first listener" and "texture consultant" most of the time. Relying on [Information Texture Discrimination], he could keenly point out subtle dissonance between a certain synthesizer tone and the overall emotional atmosphere, or where a mix balance might obscure important emotional details. His suggestions were often precise and hit the nail on the head, saving Taylor a lot of detours in her creation. Their collaboration in the studio increasingly resembled a silent, high-precision dance.

On Friday afternoon, the "detailed plan and risk assessment report" promised by Lin arrived on time. The data package was huge and tightly encrypted. Alex spent an entire afternoon in the study carefully studying it.

The core of the next phase of cooperation was a project codenamed "Echo Puzzle: History Edition." The target was not "purely natural" anomalies like ice sheets or the deep sea, but three human historical sites that had been studied by Team K for a long time and were believed to have a high degree of spatiotemporal correlation with "anomalous acoustic/energy events" recorded in history.

The first location was a large ancient city ruin deep in the jungles of Central America, which suddenly declined and was abandoned during the late Classic period of the Mayan civilization. Archaeological records and local legends both mentioned that for a period before the city was abandoned, there were persistent, unexplained "underground rumbles" and "whispers in the sky," accompanied by non-natural resonance phenomena in some building structures.

The second location was a special stone carving and burial site from the late Viking Age on the shore of a remote fjord in Northern Europe. The stone carvings and a few surviving Nordic rune records hinted that this location was regarded as a place for "listening to the voices between the dead and the world," and recorded that under specific astronomical cycles, inexplicable sounds similar to "metal singing" would appear in the fjord.

The third location was an ancient temple ruin in a high-altitude mountainous area in Asia. The temple was partially damaged and gradually abandoned hundreds of years ago due to an event of "silent thunder" and "muttering of rocks" of unknown cause, with relevant records scattered in local chronicles and monks' notes.

Team K's hypothesis was that these locations might have briefly served as receiving points, amplifiers, or interactive interfaces for some kind of "anomalous signal" in history. Their unique geographical structure, architectural layout, or cultural rituals might have inadvertently resonated with or recorded "anomalous signal sources" that periodically swept by or were briefly active. Their goal was not to dig for treasure, but to conduct precise, non-destructive acoustic and energy field scans at these locations, and cross-reference them with historical records, trying to verify the hypothesis and possibly capture the remaining, extremely weak "historical echoes" or "structural imprints."

The plan listed in detail the specific coordinates of each location, the status of the modern environment, legal and ethical risk assessments (research permits from relevant countries or cooperation with local institutions had already been obtained), logistics support plans, and estimated operation duration (about 5-7 days for each). The security level was set to "medium-high," mainly to guard against natural risks in remote areas, possible artifact theft gangs, and... the "attention from unfriendly third parties interested in similar research" vaguely mentioned in the plan.

The report emphasized that Alex's role was still "non-resident perception consultant," but in such environments full of historical and cultural atmosphere, and possibly with faint "imprints" remaining, his "perception mode" was considered to have irreplaceable value in distinguishing between natural energy residues, human activity traces, and potential "non-natural historical echoes." He needed to carry lightweight perception auxiliary equipment to conduct independent, "texture discrimination"-centered perception assessments while the team conducted routine scans.

The risk was that the environment was relatively unfamiliar and complex; the operation might involve sensitive archaeological or cultural areas, requiring extreme caution; and the existence of "unfriendly third parties" increased uncertainty. But compared to the extreme natural risks of the Greenland ice sheet and the absolute environmental isolation of the deep sea, these risks seemed more "routine" and "manageable."

Alex closed the tablet and fell into thought. This time, the tentacles of exploration reached out to human history and legends, intersecting with those ancient civilizations and beliefs. This had an extra layer of cultural depth and mystery than exploring pure natural unknowns. The attraction was undoubted.

He needed to discuss it with Taylor. The regions and cultural backgrounds involved this time were vastly different, and the travel time was longer, requiring more comprehensive arrangements.

At dinner, Alex told Taylor about the general nature of this cooperation (omitting specific locations and sensitive words like "anomalous signals," replacing them with "research on special acoustic or energy field phenomena left at specific historical sites"), and was honest about the cultural sensitivity, risks in remote areas, and the longer time away from home involved.

After listening, Taylor didn't speak immediately, but slowly took a sip of soup. Then she put down her spoon and looked at Alex: "It sounds... like a 'sound archaeology' spanning time and culture."

"You can understand it that way." Alex nodded.

"What about the danger level? Compared to Greenland and the deep sea?"

"The natural environment risk might be lower, but the human environment is more complex, and... there might be other people interested in this kind of 'archaeology,' not necessarily friendly."

Taylor was silent for a moment, her fingers unconsciously rubbing the edge of the tablecloth. "You want to go, right? Because those places might hide ancient secrets about 'sound,' and your 'ears' can hear things others can't."

"Yes." Alex did not deny it, "And this time the preparation is more thorough, and the cooperation is more standardized. I have full assessment power and decision-making power."

"Three places, adding up to maybe a month away from home." Taylor calculated the time.

"I will try to arrange it compactly, or you can... wait for me in a relatively safe, interesting transit city?" Alex suggested.

Taylor shook her head, her eyes becoming firm: "No, I won't wait in the middle this time. Either you shorten the itinerary, or..." She paused, "Or, I will also go with you to some relatively open areas that allow non-research personnel to enter, in the name of 'artistic field collection' or 'sound recording.' I can't just wait at home every time. My music also needs a wider 'field'."

This proposal surprised Alex a little, but upon closer inspection, it was within his expectations. Taylor was never a flower that needed to be kept in a greenhouse; her creative life also needed adventure and nourishment. Moreover, it was completely reasonable and common for her to go to certain historical sites for field collection in her public identity and as an artist.

"I need to evaluate the specific entry conditions and safety status of each location first," Alex said seriously, "If conditions permit, I really hope you can go together. Your ears and heart can hear 'sounds' different from mine, which would be a more complete record."

A smile appeared on Taylor's face: "Then it's settled. You are responsible for handling those mysterious 'perception assessments,' and I am responsible for collecting the 'sounds' that I can hear, belonging to people, belonging to historical dust, and the local customs of the present. We each do our own 'archaeology,' and then... come back to exchange 'artifacts'."

The two looked at each other and smiled, reaching a new tacit understanding. This time, perhaps it could become a journey of art and exploration in the true sense, together.

After dinner, Alex replied to Lin with a message, expressing his agreement in principle to participate in the "Echo Puzzle: History Edition" project, but requested more detailed feasibility assessments regarding third-party companions (Taylor) conducting legal artistic field collection at some locations, and the formulation of more detailed codes of conduct that respect local customs and regulations for the different cultural backgrounds of the three locations.

He knew that the next few weeks would be a period of intensive reading, itinerary planning, equipment preparation, and brainstorming with Taylor on how to integrate this unique experience into their future creations.

Life was once again full of predictable, knowledge-filled, and challenging distances. But this time, the call of the distance had the figure of a more explicit companion.

It was late at night, and Alex stood in front of the study window, looking at the quiet community night view. The system interface emerged silently in his consciousness, and the available popularity had quietly approached eighty million. He did not exchange for new abilities, but he could feel that [Information Texture Discrimination] and those newly added perception experiences were becoming denser and more resilient like metal that had been repeatedly hammered in the growing practice.

The whispers of history, the lingering charm of civilization, the non-natural echoes that might be hidden in ancient stones... these would all become the new anvil for his perception training, and also the new source for his joint creation with Taylor.

He turned off the light and walked out of the study. In the living room, Taylor was curled up on the sofa reading a book about Central American mythology. Hearing footsteps, she looked up, her eyes reflecting the warm light.

"Reading Mayan mythology?" Alex walked over and sat down.

"Yeah, previewing." Taylor leaned over, "Maybe their gods communicated with people using some special sound?"

"It's possible." Alex put his arm around her, and the two were immersed in the mysterious atmosphere of the pages together. The glimmer of the charm of the journey that had not yet started had quietly illuminated the night at home at this moment.
