A surge of newfound agility courses through Jinwoo. He dodges the wolf’s lunging attack with impossible speed, a stark contrast to his previous sluggish movements. Then, something even more astonishing unfolds. With a powerful blow, Jinwoo sends the wolf crashing into a wall, the impact echoing through the cavern. This display of raw strength is a revelation, a glimpse into the potential that has been dormant within him all along.

Knowing he can’t face the remaining wolves barehanded, Jinwoo delves into his inventory, a feature bestowed upon him by the enigmatic System. He retrieves the sword acquired from the Double Dungeon, the very weapon used by Kim Chul to slay the Shadow Sovereign. Now armed with this formidable blade, Jinwoo carves through the wolves with newfound confidence, each swing punctuated by the metallic clang of their demise.

With the wolves vanquished, Jinwoo takes a moment to assess his progress. He discovers he has risen in rank, his stats boosted, and his inventory enriched with valuable items. The thrill of this tangible progress fuels his determination to conquer the dungeon’s ultimate challenge – the boss.

As Jinwoo ventures deeper, he stumbles upon a sight that sends shivers down his spine – a seemingly endless swarm of steel-fanged wolves emerges from the darkness. Fear could have crippled him, but the fire of newfound strength burns brightly within. He charges into the pack, a whirlwind of steel and determination, dispatching one wolf after another. His movements are a blur, his strikes precise and deadly. By the time the last wolf falls, Jinwoo is panting, yet triumphant. He has faced his fear and emerged victorious, his spirit forged in the furnace of adversity.

The Venomous Serpent Rises

His trial by wolves concluded, Jinwoo now stands at the threshold of the boss’s lair. An unsettling silence hangs heavy in the air, broken only by the dripping of water. Then, with a monstrous hiss, the Blue Venom-Fanged Kasaka, a snake of colossal proportions, slithers into view.

The battle against Kasaka is a brutal ballet of agility and brute force. Jinwoo’s enhanced senses allow him to dodge the snake’s lightning-fast strikes, but its armored scales prove impervious to his sword. He is thrown against walls, slammed into water, and barely escapes the crushing jaws of the beast. Each blow resonates with searing pain, yet Jinwoo refuses to yield.

A Flashback, a Whisper of Motivation

In a moment of respite, a memory surfaces – Song Chi-Yul’s mocking words branding him the “weakest hunter.” This ignominy fuels Jinwoo’s will to fight. He channels his desperation into raw power, shattering his sword and gripping the serpent’s scales with his bare hands. With a Herculean effort, he tears through the Kasaka’s armor, finally delivering the fatal blow.

With the dungeon conquered, Jinwoo emerges into the familiar streets of Hapjeong. Yet, the world feels different. He is no longer the ostracized weakling, but a formidable hunter reborn. He walks past a soldier unaware of the silent guardian who just saved the city from a rampaging golem. As Jinwoo stands amidst the crowd, he witnesses the struggle of fellow hunters against the colossal creature. Recognition dawns on him – the boss is a D-Rank, no match for the E-Ranks before him.


Without revealing his identity, Jinwoo intervenes. With a flick of his wrist, he hurls the Kasaka’s sword, its trajectory carving through the golem’s defenses. This single act turns the tide, allowing the hunters to deliver the final blow. Confused whispers ripple through the crowd, searching for the enigmatic savior who struck from the shadows and that’s how the episode ends for this weekend.
