K's Cage
The finance office was quiet.
This quietness is relative. There's none of the cacophony of keyboards, voices, and low-quality music from the outside "office area," nor the crowding and stench of the dormitory area.
The quiet here comes from the deep hum of the equipment running, the steady rotation of the server fans, and the hissing of the airflow from the central air conditioning system—precise, constant, and carrying the unique coolness of electronic devices.
The room is about forty square meters and has no windows. The walls are covered with a smooth, gray coating that can block signals to some extent. Four recessed LED lights are evenly distributed on the ceiling, providing bright, almost blinding light and ensuring that there are no shadows in any corner.
At opposite corners of the room, there is a small, hemispherical black camera with a deep lens that flashes a faint red light 24 hours a day, signifying uninterrupted surveillance.
K sat in the center of the room, at a large L-shaped desk. Four ultra-thin monitors were placed side by side on the desk, their screens constantly displaying complex charts, data streams, account lists, and encrypted transaction information.
He was wearing the same dark blue polo shirts worn by the park's "management" staff, his hair was neatly combed, his expression was focused and calm, and his fingers danced quickly and precisely on the mechanical keyboard, occasionally moving the mouse and clicking to confirm. He looked like an ordinary, unassuming tech expert focused on complex financial operations.
In fact, this is exactly the kind of work he is doing.
The screen displays an overview of the fund flows generated in this massive telecom fraud park over the past 24 hours. From the "small change" of tens or hundreds of dollars swindled by the lowest-level "dog pushers," to the tens or hundreds of thousands of dollars harvested by the mid-level "pig butchering" scams, and then to the occasional "big fish" swindled at the million-dollar level by sheer luck, all the funds flow like rivers into the sea, undergoing cleaning, diversion, and re-aggregation along the dozens of intricate channels he designed and optimized.
Cryptocurrencies, offshore shell companies, fictitious trade, underground banks... a variety of methods are used in combination to ultimately transform this money, tinged with bloodshed and deception, into seemingly legitimate investments, consumption, or savings, flowing into different accounts around the world.
He did a great job. He was at least three times more efficient than the half-baked money laundering experts the "general" used to rely on, and much more discreet and secure. That's the value of him being allowed to sit here and control everything.
But value also means imprisonment.
K's gaze didn't leave the screen, but out of the corner of his eye, he could clearly see, about three meters behind and to his right, the bodyguard leaning against the wall, arms crossed, with a walkie-talkie and baton hanging from his belt.
His A Long, one of the two bodyguards personally assigned by the "General" to "protect" (or rather, guard) K. The other one A Hu, and he should be guarding outside the door right now. The two of them take turns every eight hours to ensure that there is always a sober, fully armed guard within K's line of sight.
K's "freedom" is limited to this room and an adjacent, less than five-square-meter, surveillance-monitored bathroom. Three meals a day are delivered to his door by a kitchen staff member, and then handed in after being inspected by a guard. He doesn't need to leave, nor can he leave.
He moved the mouse and clicked on a seemingly ordinary internal management interface. It was a rudimentary local area network OA system built by the park itself, used to issue notices, register materials, and arrange internal security shifts. The interface was crude, the permission division was chaotic, and it was full of loopholes. In K's eyes, it was practically an undefended backyard.
He certainly wouldn't use this heavily monitored mainframe to perform any sensitive operations. He pressed his fingers three times in a very discreet groove beneath the keyboard, using a specific rhythm.
This activated a miniature signal repeater, which he had hidden in a compartment of the tabletop using a special process.
This transponder captures the extremely subtle vibrations produced when his fingertips tap the keyboard, encodes them into specific commands, transmits them through the table legs to the floor, and then connects to a matchbox-sized, completely physically isolated one-way communication node he had secretly placed deep inside the ventilation duct via nanoscale wires disguised as dust fibers.
At this moment, he is using this absolutely secure, clandestine channel—undetectable by any existing surveillance technology—to retrieve information he had collected and organized while "wandering" this dilapidated internal network.
In my consciousness, the information flow is clearly presented:
3D modeling of the park structure (based on surveillance camera views, maintenance records, and internal security chat information):
His "finance building" was a separate two-story building. The first floor housed ordinary clerks and supplies, while the second floor contained the core finance office and the adjacent "General's" temporary rest room (which was rarely used). This building was the most heavily guarded, with two fixed posts downstairs in addition to A Long A Hu, and sniper observation posts on the roof (but these posts were often empty).
The main building (where the "General" resides, and where he conducts entertainment, holds meetings, and detains special personnel) is located in the center of the park. It is a three-story reinforced concrete structure with only one main entrance and two emergency exits. The General's eight-man personal guard (well-equipped and highly trained) guards the building day and night, forming the core of all armed forces. After cross-verification of information from multiple sources, the armory is preliminarily determined to be located in a reinforced room in the basement of the main building, requiring a special password and Key, and is directly controlled by the captain of the guard.
The security guard dormitory, the regular "piglet" dormitory, the canteen, and the work area are distributed around the perimeter. The surveillance coverage is high, but there are more than a dozen blind spots due to aging equipment, damaged lines, or simply being forgotten. These are mainly concentrated along the edge of the wall, in the garbage dump area, and behind the old warehouse.
The most important finding: there were significant periods of laxity in the internal security patrols and sentries—between 3 a. m. and 4 a. m.
This is when the human body is most physically tired, and it is also the window period between the night patrol and the morning shift change, when vigilance is at its lowest. Many sentries will even secretly doze off. This is the conclusion he came to after repeatedly checking the internal security shift handover records of the past month, the guard status in the surveillance footage, and even listening to their idle chatter and complaints.
Personnel dynamic monitoring (based on OA system scheduling, kitchen requisition records, and sporadic conversation capture):
A new batch of "piglet" arrived today, about thirty people. The OA system briefly recorded their assignments. K noticed that the "remarks" column of seven or eight of them was unusually clean, or the "skills" they filled in did not match the typical identity of illegal immigrants (such as "can do simple electrical work", "have worked as a kitchen helper", etc., which seem deliberate in this context).
Two of them were even directly assigned to the kitchen and maintenance team—two seemingly inconspicuous places, but which allowed them relatively free movement within the park, access to water and electricity, passageways, and even... certain tools.
A Long's walkie-talkie just picked up the routine report from the guard downstairs, mentioning that "the new recruits are all fairly well-behaved and have been assigned to their posts." His tone was normal.
K's gaze swept across the scrolling financial data on the screen, and his right hand typed a command on the keyboard, causing a set of funds to automatically jump to different batches. His brain, however, was simultaneously processing another stream of information.
Those seven or eight new recruits with "abnormal notes"... Time point. He glanced at the internal network time in the lower right corner of the screen without showing any emotion. From the time he last reported the situation to Lin Feng until now, it has been about sixty hours.
Lin Feng said at the time, "Wait for my news." And today, a group of somewhat "special" newcomers have arrived.
Is it a coincidence?
A faint, data-like glint seemed to flash for a moment deep within K's eyes. In the probability assessment, the likelihood that "external intervention has begun to infiltrate" rapidly increased from less than 5% to 65%.
He didn't look at A Long, nor did he make any unnecessary movements. He remained focused on the screen, processing yet another cryptocurrency exchange. But his left hand, under the table, at an angle completely out of the camera's view, lightly touched a tiny protrusion on the inside of his belt.
It was a biosignal sensor, also disguised. At that moment, it sent an extremely brief, encrypted, preset signal representing "all is normal, stable, waiting" to the node hidden deep in the ventilation duct, with a specific heart rhythm.
The signal will travel through multiple redundant paths and random delays, eventually reaching distant places in an untraceable manner.
After sending the message, K naturally withdrew his left hand and placed it back on the keyboard. He slightly turned his head to look at a small window on the side of the screen, which displayed real-time monitoring footage of several key locations in the "office area" (he had this permission to "monitor the capital production end"). In the footage, people were bustling about, each wearing headphones, speaking or typing into the screen, with varying expressions.
His gaze seemed to linger on those blurry faces for a fraction of a second longer.
Then, he turned back, pushed up Glasses that weren't actually on his nose (a habitual action), and focused all his attention back on the complex financial network in front of him.
Inside the finance office, only the hum of the equipment and the crisp sound of his typing could be heard.
A Long leaned against the wall, yawned, shifted to a more comfortable position with his arms crossed, glanced at K's Back View, then listlessly looked away, his gaze landing on the blank wall opposite.
Everything is as usual.
