SPOILERS: The Story of Act 4 of Blade and Soul

As the Blade and Soul narrative reaches its zenith in ACT 4, players encounter the most emotionally charged and lore-rich segment of the game. This act serves as the culmination of numerous story threads that have been developing since the beginning, providing answers to longstanding mysteries about character relationships and historical events.

CRITICAL SPOILER ALERT: This comprehensive guide contains extensive story revelations that will spoil the campaign experience for players who haven’t completed these quests.

The fourth act commences with “the road to darkness,” where your character demonstrates unprecedented determination in pursuing Jinsoyun, even aligning temporarily with the Empire Army to achieve strategic objectives. Beyond the central conflict, this segment unveils crucial background information including Namsoyoo’s complete lineage, the circumstances surrounding Chen Su’er’s father’s demise, the romantic history between Emperor Wan and Namsoyoo’s mother Nan Xueling, and the political motivations behind the establishment of the Talus Dominion.

Progressing through the narrative, your character confronts the legendary Eight Masters in a series of martial arts trials that test both skill and spiritual fortitude. Following intense combat exchanges, these masters make the ultimate sacrifice—voluntarily giving their lives to purify the Dark Chi corrupting your essence and neutralize the Mark of the Black Rose. This cleansing ritual represents one of the most pivotal moments in the game’s spiritual mechanics.

At this narrative crossroads, you face a defining decision with profound implications for your character’s development: persist along the treacherous path of darkness or return to the enlightened road of Hoonmoon. This choice significantly influences not only immediate outcomes but also long-term character alignment and available quest paths.

Selecting the Hoonmoon path triggers an extraordinary temporal journey to a previous era, unveiling the complex relationships between Mushin, Jiwan, and Jinsoyun. During this historical period, Mushin suffers from severe Dark Chi corruption that compromises his mental stability, with a fragment of the Dark Lord entity sealed within his physical form. The malevolent being manipulates Mushin’s compromised state, seeking to harness the Twilight’s Edge power to shatter its confinement.

Tragically, Jiwan had previously expended his entire Chi reservoir to heal Jinsoyun, leaving him critically weakened. In his corrupted state, Mushin assaults Jiwan and attempts to coercively obtain the Twilight’s Edge from Jinsoyun, though his scheme is interrupted by the timely arrival of Iksanun and Hong Sokgyun. Both newcomers mistakenly attribute Jiwan’s injury to Jinsoyun, influenced by her possession of the legendary sword and Mushin’s deliberate false accusations.

Before Jinsoyun can provide her account to Hong Sokgyun and Iksanun, Mushin attempts to deliver a fatal strike, which Master Jiwan intercepts at the cost of his own life. Witnessing her mentor’s sacrificial death, an enraged Jinsoyun unleashes her full power, wounding Mushin with the very blade he coveted.

Following this confrontation, Hong Sokgyun strikes Jinsoyun, sending her plummeting from a cliff while reclaiming the sword. This traumatic experience generates three profound negative emotions—grievance, agony, and vengeance—that coalesce within Jinsoyun’s consciousness, trapping her spirit between realms and preventing natural reincarnation.

The Dark Lord capitalizes on this spiritual vulnerability, tempting Jinsoyun to embrace the path of darkness. The entity reconstructs her physical form and imbues her with demonic abilities. From this moment forward, revenge becomes Jinsoyun’s singular driving purpose and reason for existence.

In Chapter 29 of Act 4, Jinsoyun employs Namsoyoo as a psychic conduit to perform a terrifying ritual aimed at summoning the Dark Lord into the physical realm. Amid the chaos unleashed by Jinsoyun’s actions, Emperor Wan and Junghado make their dramatic entrances, while Gwon executes a daring rescue of Namsoyoo.

Mushin, having acquired the Twilight’s Edge, develops an inflated sense of invincibility and selects Su Linglong as his psychic medium to establish connection with the Dark Lord. However, Jinsoyun has been anticipating this development, strategically using the Twilight’s Edge to eliminate Mushin and rupture the dark seal within his body, thereby returning the Dark Lord to its native Dark Realm.

Observing Mushin’s catastrophic failure, Yura attempts to assassinate Jinsoyun but is thwarted by Gubong, who strikes her down from the God’s Will Altar. (This represents General Gubong’s sole positive action in the entire narrative.) Yura emerges as the original instigator who breached Mushin’s Seal, explaining his awakening after millennia of dormancy. Jinsoyun possessed awareness of the Dark Lord fragment within Mushin from the beginning of their conflict.

At this decisive juncture, your character demonstrates exceptional courage by intervening to thwart the Dark Lord’s scheme and ultimately overcoming both Jinsoyun and her corrupted manifestation. However, as Mushin’s designated medium, Su Linglong becomes transported to the dark realm. Faced with this moral dilemma, your character ultimately makes the heroic choice to relinquish the immensely powerful Twilight’s Edge to rescue Su Linglong from eternal imprisonment.

This final sacrifice represents one of the most emotionally resonant moments in Blade and Soul, demonstrating that true power lies not in possessing legendary artifacts but in the strength of one’s convictions and willingness to sacrifice for others.
