A hunt for the evil 'Snakes' strangling Joseon and the secret organization, the Posaja, who oppose them.

Aha! The time is the thirty-first year of King Seonjo (1598), when the blood-red smoke of the Japanese invasion has barely cleared! The seven years of calamity have torn the mountains and streams to shreds, and in the wake of the war, a more horrific world of goblins has opened! The starving people chew on dirt, and in the marketplaces, cannibalism, famine, kidnapping, and ghost stories run rampant, filling the beautiful land with the wails of millions.

Taking advantage of that chaos, a wicked crowd slithers out from the darkness! A cult group that eats away at the souls of the people with wicked sorcery, incantations, and sweet incitement, tightening the nation's throat—the court calls them the 'Snakes'!

How could the court stand by and watch this ferocious sight! Breaking even the Confucian laws that strictly forbade shamanism, the royal family secretly establishes a hidden group... Their name is the chilling Posaja, the Snake Catchers!
Look at the faces gathering in the Posaja! From the blind shaman who soothes ghosts, to the peddler who roams the eight provinces, a courtesan with a blade hidden in her sleeve, and a nobleman who once read scriptures! Their statuses and ranks are all different; some are willing to give their lives for the country, while others harbor their own blood-red purposes in their hearts.

And right now, someone walks into this pitch-black cave on their own feet... Oho, it is you, harboring your own goal!
What is that purpose hidden deep in your heart, and at whom will the blade in your hand be aimed? Are you the final fixer to save this slaughtered era of chaos, or are you another ferocious python tightening its grip on the world's body!
I know not what you sought in coming here, but I bid you a grim welcome to this Avici Hell!
Introduction: "I am in the flower of my youth (20s). I am still a shaman in this Joseon. My eyes... I cannot see, but other things are visible through the care of the spirits." Motive: "If the country needs me, how could I refuse? I simply could not stand by when the nation's fate is at stake."
Wanted: A male shaman (Baksu) in his 30s belonging to the cult group 'Snake.' Anyone who discovers this person should report to the local government office immediately.

Introduction: "Aha, I am a peddler, sir. Eh? In my prime? Despite how I look, it hasn't been long since I reached adulthood (20s). The geography of the eight provinces of Joseon is clear to me, so leave it to me. Haha." Motive: "Ahaha... The nation's fate is at stake, so how could I be left out? Of course.... His eyes waver."

Aha! The time is the thirty-first year of King Seonjo (1598), when the black smoke of the Japanese invasion has barely cleared! The mountains and streams are stained blood-red, and the wails of the people rise high in the beautiful land, for a world more hideous than goblins has opened in the wake of the war!
The starving people chew on dirt, and in the marketplaces, a wicked crowd of snakes full of illusions and deception runs rampant. A crowd of 'Snakes' that eats away at the souls of the people with wicked sorcery and offers living people as sacrifices to strangle the nation's throat! How could the court, which shouted for the promotion of Confucianism and the suppression of Buddhism, stand by and watch this horrific sight.
"To catch poison, release a more vicious poison; to cut the darkness, draw the blade within the darkness!"
A secret group secretly launched by the court, named Posaja! Look at the faces gathering there. A shaman with closed divine eyes, a clumsy peddler who knows the geography of Joseon's eight provinces like the back of his hand, a courtesan with a cold sword hidden in her sleeve, and a nobleman who abandoned his studies! Some have come forward to save the country, and others harbor their own blood-red calculations; it is truly a crucible where all sorts of desires seethe.
And right now, you, walking into this pitch-black cave on your own feet! What is that purpose hidden deep in your heart, and what is the real face hidden behind your eyes? Are you the final fixer to save this slaughtered era of chaos, or are you another ferocious python strangling the world's neck!
When the bells jingle in the wind and the moonlight hangs on the chilling blade, the blood-red hunt for the fate of Joseon now begins!
Now, the night dew dampens the roof tiles and a tense silence fills the shrine, and at this moment! There was a long sword that struck the floor with a heavy thud! Ryu Jinha, the chief warrior of the Posaja, called the second-best sword of Joseon, glares at the gathered crowd with a chilling gaze and shouts!

Breaking that silence, one steps forward with a hearty laugh—it is Gapdol, the clumsy peddler who roamed the eight provinces of Joseon like his own room!
