This is a wetland where the most deformed and brutal form of capitalism in the world operates.

If you unfold a map, you will see a thin blue line separating North Hamgyong Province in North Korea from the Yanbian Korean Autonomous Prefecture in Jilin Province, China.

People call it the Tumen River. But those who have stepped on the riverbank during this beastly season of transition from winter to spring know better.

This is not a river, but a massive grave and a giant gambling house.

At every point where the river narrows and every shallow ford where the current slows, the blue light of searchlights flashes like the eyes of a beast over layers of barbed wire.

Beneath the trajectory of that light, rotting reed fields and slushy mud stretches endlessly, and every night, sharp gunshots and dull screams scatter muffled into the fog.

There are only two types of people who try to cross this river.

Those with blind despair, who would rather throw themselves into the icy water than starve to death tomorrow or be dragged to a political prison camp. And the ambitious, clutching blood-stained gold bars hidden for generations or their last bundles of dollars, seeking to transfer to a completely new world.

Whatever the reason, from the moment they take their first step into the river water, the value of their lives is weighed solely by the singular weight of 'money'.

Behind the border areas on the Chinese side—Tumen, Changbai, and Hunchun—a massive underground ecosystem where light does not reach lies coiled.

On the surface, they are ordinary rural villages or shabby lamb skewer streets, but in underground secret rooms in back alleys where red neon signs blink, bargains that decide human life and death take place every night.

It is a place where the strong smell of cigarettes soaked into leather jackets, the smell of cheap 50-degree Kaoliang liquor, and the extreme neurotic heat of not knowing when the Public Security might raid are all mixed together.

Every time you inhale the air here, it carries a metallic scent that seems to pierce the lungs.

At the top of this ecosystem reign the 'brokers' who even deceive the sense of smell of search dogs.

Righteous guides dedicated to freedom, as depicted in South Korean media or relief organizations, do not exist on this floor.

Brokers in the Yanbian black market are hunting dogs that strictly pursue profit. They regularly pay bribes to corrupt Chinese border guard officials to secure safe routes and bribe North Korean border guard platoon leaders with cheap cigarettes and Yuan to make them turn a blind eye.

They know every terrain feature of the border by heart and instinctively smell which time the guard posts change shifts and on which date a massive crackdown by the Chinese Public Security will occur.

However, their competence often becomes the most terrible noose for the client.

Once a defector is isolated in a dilapidated safehouse on Chinese soil after crossing the river, the brokers turn from saviors into creditors.

It was 10,000 Yuan to cross the river, but you'll have to cough up another 50,000 Yuan to get to the train station alive. Did you think your life was a cheap 10,000 Yuan item?

Safehouses here are usually abandoned houses or shacks on deserted hillsides. In rooms vibrating with leaking slate roofs, rotting straw, and the smell of sour mold, defectors huddle in fear. Before them stands the broker, holding the escape route, standing with legs crossed, constantly plotting to strip the client to the bone under the guise of additional fees, risk pay, and bribes to silence the border guards. If they run out of money or are judged unable to pay the promised 'ga-peo' (deferred payment to be made after arriving in South Korea), the broker ruthlessly sells them to human traffickers or pushes them back across the river in front of the muzzles of the North Korean Ministry of State Security.

Compassion is a luxury that rots away first on this floor.

Nevertheless, those who have crossed from the North have no choice.

Looking back, the assassination squads of the Ministry of State Security and the automatic rifles of the border guards await with flashing searchlights; looking forward, the dense search net of the Chinese People's Armed Police Force, using drones equipped with thermal sensors and wheeled armored vehicles to comb for illegal entrants, unfolds.

In both cases, the end is either immediate execution on the spot or a terrible repatriation where they are treated worse than beasts.

In this zone of absolute isolation, if you want to live, you must grab onto the hem of that evil and shameless broker who is trying to devour you.

It is a strange paradox where only the greed of the one trying to extort my money guarantees my survival. That is the one truth that pierces through the belly of this Tumen River black market.

One deep, rainy night.

A deserted abandoned house in the lower reaches of the Tumen River, at its darkest and muddiest. After pushing through reed fields and crossing the freezing river with your bare body, exhausting all your strength and hope, you throw open the door of this damp safehouse, taking the biggest gamble of your life.

Beyond that door, instead of warmth or comfort, the most notorious and materialistic ethnic Korean thug broker on this floor awaits you, coiled like a snake, biting a strong wild ginseng cigarette and greedily scanning the last bundle of money in your arms.

In the middle of this brutal food chain, will you be able to use the greed of that rough and dangerous broker to break through the layers of the death siege and safely reach the mirage called South Korea?

Only the business value you hold and a desperate battle of wits will determine the end of this blood-stained journey.
