The third chapter of Solo Leveling Season 2 unfolds with Jinwoo and Jinho triumphantly mastering a dungeon and amassing its mystical gems. Simultaneously, a figure later identified as Sung II-Hwan confronts another gentleman aboard a dilapidated vessel, while his comrades lie stranded below. Assuring his companion of their well-being, II-Hwan expresses his yearning to return home.
Elsewhere, Jinwoo and Jinho celebrate their triumph at a cozy restaurant. Jinwoo beams with satisfaction as they successfully complete all nineteen quests. Jinho reveals his plan to acquire a guild master’s license, which he intends to leverage as a bargaining tool with his father, Myunghan. Jinwoo then announces his intention to visit a private locale, prompting Jinho to confess his wish that Jinwoo were his actual brother. Jinwoo, in turn, warmly embraces Jinho, pledging to be his brother.
Meanwhile, II-Hwan finds himself imprisoned. Two men converse about his plight, revealing that they confined him due to suspicions that he might be a humanoid beast. They affirm that they have reported II-Hwan's situation to Dongsoo and will resume their investigation upon his return.
As for Jinwoo, he ventures back to the Demon's Castle—the very fortress where he battled Cerberus in season one. Equipped with his key, Jinwoo enters the premises and receives a quest notification from the Player Log, tasking him with gathering 10,000 demon souls.
Concurrently, Jinho pays a visit to Myunghan, demanding the Yoojin Guild. Myunghan, accommodating Jinho's request, stipulates that Jinwoo must be recruited into the guild.
In this vivid narrative, the stakes are raised, emotions deepen, and the journey of our protagonists takes another intriguing turn.
Jinho comprehends the situation fully. Meanwhile, Jinwoo vanquishes numerous demons, yet he finds himself unable to extract their shadows. The logbook presents Jinwoo with an Entry Permit, granting him access to the second floor of the area. Summoning the formidable Ice Bear boss, Jinwoo leaps atop its mighty form and spots a horde of demons approaching. Together, he and the Ice Bear engage in a fierce battle with the demons. Jinwoo names his Ice Bear boss "Tank," adding a personal touch to their alliance.
Elsewhere, Hae-In swims laps in a public pool, her mind drifting back to her conversation with Choi on Jeju Island. Choi had only disclosed the island's flying ants to a select few, a decision Hae-In fiercely argues against, believing he should have informed the public. Choi counters that the association had forbidden him from sharing such information, redirecting their focus towards becoming the nation's largest guild.
As Jinwoo's journey progresses, he amasses an impressive total of 10,000 demon souls. Eventually, he confronts the Lord of the Lower Floors, Avaricious Vulcan, and his formidable army. Leveraging his shadow soldiers and unparalleled strength, Jinwoo emerges victorious, overcoming Vulcan and his minions.
Simultaneously, Dongsoo grills II-Hwan, who insists that a force far more menacing than dungeons, gates, and magic beasts looms on the horizon. II-Hwan is driven to prevent this unknown force from causing untold devastation, emphasizing humanity's helplessness against it. He reveals his son's name to Dongsoo, who senses II-Hwan's sincerity but cannot shake off his own murderous intent. The confrontation between the two escalates into a violent clash, causing widespread devastation in the city as firefighters scramble to clean up the aftermath. Witnesses confirm that II-Hwan has emerged victorious over Dongsoo.
Meanwhile, Jinwoo reflects on his journey through the Demon Castle, having reached the 75th floor. He muses that he has already acquired two of the three materials needed for the Elixir of Life. The episode concludes with Jinwoo setting out on a new quest, vowing to obtain the final item soon, his determination etched in every stride he takes.
