I, the screenwriter, have experienced a resurgence of inspiration.

It started raining in the port city in the middle of the night.

In the inverted dungeon world, the shadows cast by the rain create the illusion that one is still in the mortal realm.

As the Song Dynasty drew to a close, details were gradually added to the dungeon, with textual materials falling to the ground and slowly merging into it.

She didn't rush to edit the rules directly.

It's a bit of a waste to use the space of a replica of the port city, which is almost a one-to-one replica, to make a replica of just one building.

If the script "The Underworld Messenger's Life Extension" is the starting point, using the old grudges of the Chen family to bring the concepts of the underworld and underworld messengers into reality—

So this copy is to bring the existence of the "underworld" to life.

Then we need to have the concept of the "underworld" first.

Starting with a grand narrative like the Ten Kings of Hell and the Six Paths of Reincarnation clearly doesn't consider the audience's tolerance or the script's plausibility.

The revival of spiritual energy is just beginning, and the rules of heaven and earth are still loosening, so the underworld cannot appear in the world all at once.

Like the first thaw of spring ice, when fine snow is thrown into a furnace, it first melts the surface ice, then melts the snow deeper inside—

Wandering ghosts and spirits, low-ranking underworld officials, then city gods and judges, and finally Yama and Ksitigarbha.

A step-by-step, gradual approach aligns with the logic of creation.

Therefore, the building in this instance cannot just be a haunted, unfinished building.

It has to be an entrance, a node, and preferably a narrow crevice where yin and yang meet.

……

……

"...People from the living world can come in, and the underworld officials can go out to imprison the souls of the dead."

The living can see their deceased relatives here, and the souls of the dead can take one last look at the world of the living...

There are transactions, rules and order, but there should also be hidden dangers... just like the Yin-Yang Ghost Market in supernatural tales.

At the end of the Song Dynasty, the script in the air was deleted and revised again:

"This building can be seen as the core anchor point. After players enter the instance, their movements are not restricted, allowing them to explore freely."

"We can't just tell the players that this is a part of the underworld right away... We need to maintain the mystery and let them explore and draw their own conclusions..."

……

Once you get the gist of it, the rest is easy to follow.

At the end of the Song Dynasty, his hands flew as he began to build the underlying framework of the entire instance.

[Setting 1: This area is a buffer zone between Yin and Yang, a prerequisite dungeon for the Underworld system, and a gathering place for low-level wandering souls.]

【Setting 2: Yin and Yang are separated, and mirror images coexist. The sky in the instance is a reflection of the Yang world, where one can see the bustling human world, but cannot touch it.

The ground is a ghost realm; living people are forbidden to enter the mortal world.

[Setting 3: The Ghost Market is centered on trade, where everything can be exchanged, including memories, luck, virtue, items, and even human lives.]

Transactions require the voluntary consent of both parties; a contract is binding and effective upon signing. Those who renege on their agreements will face legal repercussions.

[Setting 4: The underworld messengers patrol the city daily.]

……

[Setting 7: Golden ghost money will randomly fall into the mortal realm. Whoever picks it up will gain entry and will automatically enter the instance at midnight.]

……

……

Song Mo wrote very slowly because she had to carefully consider every rule.

Too loose, and it fails to display the majesty of the boundary between yin and yang.

It's too strict; players have no room for maneuver.

In short, the trading rules are the core of this ghost market – the ghost market is, in essence, a place for buying and selling.

Humans and ghosts do business together.

Ghosts do business with other ghosts.

Players can also get involved.

As for whether it's exchanging opportunities, items, information, or even buying and selling oneself... where there's a transaction, there's calculation, and where there's calculation, there's a story.

The playability of the dungeon immediately increased.

……

Meanwhile, Song Mo was engrossed in writing the rules, and the tall buildings around her moved like building blocks as she created them.

On the other side, A Zhu's shadow transformed into countless tentacles, carrying hundreds of clay ghosts of varying sizes and throwing them into the ghost market.

—A-Yan had to stay home to guard the house, so the person who accompanied Song Mo on this business trip was changed to the vengeful ghost A-Zhu.

Unlike her lively younger sister, Azhu was more silent.

[Chirp chirp chirp!]

[Squeak squeak squeak!]

One by one, round, plump clay gourds with small heads and large bodies took root on the ground, and soon split off into new clay ghosts.

As Song Mo's words "Clay Sculpture Ghost Shop" fell from his hand, dozens of small temples covered with red cloth suddenly appeared in inconspicuous places such as corners of corridors, edges of rooftops, and depths of alleys.

After completing the framework, she then filled in the background of the ghost market, comparing it to reality.

The musty smell of the old tenement building mingled with the scent of incense and candles, and the rusty neon signs glowed green.

A cart selling fish balls was parked in the narrow alley, and wet human skin hung from the clothesline overhead.

Beneath the faded Cantonese "GG" stickers plastered on the wall were rows of pale, grotesque faces:

[Unblock drains and repair leaks.]

[Inquiry into spirits, chanting sutras, and bone setting for injuries.]

When something normal appears in an abnormal place, the sense of strangeness accumulates little by little, and the resulting fright multiplies.

"...The dungeon will attract real-world ghosts to enter, and the underworld messengers will also leave the dungeon to go to the real world to collect souls."

Song Mo sighed softly, and countless words flowed from her fingertips—

Like a fine rain, falling into the crack between light and shadow.

hum...

hum...

A silent, invisible wave emanated from her, and A'Zhu, not far away, immediately bowed her head in reverence.

A gust of wind swept by, and the clouds and mist above the entire instance dispersed, projecting the hurried pedestrians and bustling traffic of the real world into the instance.

The sounds of talking, horns, and shopkeepers' shouts seemed to separate two worlds through a mirror.

And Song Mo stood right at the center of this upside-down world, watching the "rain of words" sweep in countless ghosts—

The ghosts of the revitalized port city, drawn by the rain, swarmed into the instance like a school of sardines, passing through the thin barrier.

These ghosts all retain the appearance they had when they died.

Some were covered in blood, some were charred black, some were soaking wet, and some were torn to pieces.

Thousands upon thousands of phantoms came together, each soul seemingly frozen in time, lying motionless on the ground.

……

[Add premium content featuring White Impermanence and Black Impermanence.]

As the writing progressed towards the end of the Song Dynasty, two enormous, sky-obscuring phantoms rapidly expanded, sucking away the surrounding light like black holes—

[Instance: The Port Building is Haunted]

The thirty-three-story building soared into the clouds, its densely packed window frames resembling dark, gaping eyes. Suddenly, two ghostly figures, one black and one white, appeared behind the building, their height almost invisible.

A woman with a white veil covering her face, holding a mourning stick.

A person with a black veil covering their eyes, holding an iron chain.

The air was sticky, and the two giant shadows almost blended into the background.

But if you just look up, you can see huge ghost messengers moving between the buildings, their chains rattling loudly.

Ghosts are like a school of fish being chased by a giant beast in the deep sea.

The underworld messengers can capture and subdue vengeful ghosts.

The moment the black and white shadows appeared, A'Zhu immediately hid in the shadows of the late Song Dynasty.

This is a fear etched into one's bones, and it is also a setting written into the script by the end of the Song Dynasty.

……

The next second, the entire instance suddenly shuddered.

The once still fog began to move slowly.

The wind in the alley swirled up ashes from the paper, and the neon signs hissed.

The fish ball cart on the street moves automatically without wind, and Cantonese characters fall one by one, with the mouths of the ghost faces hidden underneath opening and closing, like goldfish begging for food.

The frozen spirits suddenly found their direction and began to wander slowly.

Some went into shops, some squatted by the roadside, and some stared blankly at the mirrored sky.

The sounds of hawking, footsteps, coughs, the crackling of a radio, and the faint strains of Cantonese opera gradually rose up.

The enormous Black and White Impermanence figures swayed slowly in the mist, glanced down at the ghost market beneath their feet, and strode forward:

"Pass--"

"Pass--"

"Pass--"

Under immense pressure, the wandering spirits scattered and fled.

Growing from the dark ground were rows of leafless, eerily colored ghost flowers.

The copper coin trees sway in the wind, and the fallen leaves look just like copper coins.

……

Alive.

The entire instance came alive.

Scenes built from words, cold rules and regulations, became reality in the writings of Song Mo.

Humans and ghosts coexist, yin and yang are reversed.

Song Mo let out a satisfied sigh.

How could she not be captivated by this?

Now that we have dungeons, NPCs, and native inhabitants, all that's left is for players to enter.

The copper coin tree swayed, and golden "copper coins" soared upwards, piercing the boundary between life and death and falling into reality.

……

……

……

In the real world, Mong Kok.

"What is this?"

A taxi driver waiting for passengers suddenly noticed leaves falling from the sky and curiously poked his head out to look.

Outside the car, tourists and Hong Kong residents stood still, all looking up at the sky—where large swaths of dark clouds were gathered.

And from within the dark clouds, countless golden copper coins were scattered across the sky.
