Impermanence Sword

Impermanence Sword is a heart-bound immortal sword whose significance grows from seo Eun-hyun's completed Immortal Art and sword-centered Immortal body, joining life, death, connection, and the Three Great Ultimates. It remains his primary True Immortal weapon and path. Its changing use links personal inheritance to the larger struggle over travel, authority, survival, and ascension. (Chapters 536, 538, 539, 540, 541, and 573)

History and use

Seo Eun-hyun's completed Immortal Art and sword-centered Immortal body, joining life, death, connection, and the Three Great Ultimates. It remains his primary True Immortal weapon and path. The item remains materially important because its power changes what its wielders can reach, survive, command, or preserve; references to copies or transformed forms are not treated as proof that every instance is the same physical object. (Chapters 536, 538, 539, 540, 541, and 573)

Wielded by Seo Eun-hyun; reads and carries hearts, directs counter-dances, and becomes inseparable from his late True Martial expression. Chapter 855 is an Earth-side generic homonym and is excluded. The item remains materially important because its power changes what its wielders can reach, survive, command, or preserve; references to copies or transformed forms are not treated as proof that every instance is the same physical object. (Chapters 583, 584, 585, 586, 589, and 806)

Properties and limitations

The Impermanence Sword does not grant unlimited power. Its performance depends on custody, condition, the wielder's cultivation, and the surrounding formation or realm. When the story distinguishes an original from a replica, a later completed form, or a manifested version, those states are treated separately even when they share the same name. (Chapters 789, 790, 800, 801, 804, and 806)
