None. No independent shrine, stone tablet, or text dedicated solely to the Sword of Immortal Entrapment is recorded. Its existence is primarily known through the *Fengshen Yanyi* and the broader lore surrounding Tongtian Jiaozhu and the Immortal Slaying Formation.

The Sword of Immortal Entrapment is intrinsically linked to the sword array of its master, Tongtian Jiaozhu, the former leader of the Jie Sect. Its primary companions are the other three swords of immortal slaying, which together form one of the most dangerous war arrays in the mythic tradition. The principles of entrapment that define this sword are born from the lingering will of a primordial entity known as the Chaos Walker, whose consciousness was fused with the dying core of a star during the sword's forging. A full understanding of this sword's nature requires also knowing the history of the Fengshen Yanyi and the final fall of the Jie Sect.

The Sword of Immortal Entrapment is the third of the Zhu Xian Si Jian, the Four Swords of Immortal Slaying. Its tier is that of a Zao Hua Xiong Qi, an artifact whose very existence is a crime against the natural order. Unlike its siblings, which govern judgment, slaughter, and extinction, this sword specializes solely in the principle of entrapment. Its primary function is to release an invisible force known as the 'Entrapment Domain,' which twists the laws of space and time within the sword's array. It transforms the surrounding space into a layered, infinite maze and stretches time into an eternal, frozen moment. An enemy caught within this domain is like an insect sealed in amber; no matter how they move or shift, they can only cycle endlessly through the compressed space-time, eventually perishing from exhaustion and despair, their life force becoming fuel for the sword's own matrix. The sword's ability to generate this field is absolute within the bounds of the Immortal Slaying Formation, but the extent of the domain is tied to the wielder's cultivation and the stability of the array. A minimum of a high-grade Daoist cultivation is required to even attempt to activate the sword without immediate backlash.

The core of the Sword of Immortal Entrapment is forged from the **primordial core of a dying star**. This was not a simple mining operation; it was an act of cosmic harvest. The star, on the verge of collapsing into a dead husk, had its nascent singularity—the concentrated essence of its gravity and potential—extracted before its natural death. This act robbed the stellar system of its final, terminal gravitational event, effectively cutting short the cycle of a small constellation. The extraction process itself is said to have permanently scarred the region of space, leaving an area of gravitational instability where the star once burned. The star's core was not merely a material; it carried within it the memory of collapse, a deep, cosmic inertia that desires to drag everything into its final, silent compression. This residue is the foundation of the sword's entrapment power.

The Sword of Immortal Entrapment contains a Qi Ling that was never born—it was forced into existence. The spirit within is the remnant of a tortured consciousness known in fragmentary texts as the 'Chaos Walker,' an entity from the Tai Gu (太古) era who was twisted by a grudge so profound it warped its very existence. This being was not sacrificed in a furnace; its soul was *stretched* and *woven* into the star core matrix as the sword was forged. The process was not a clean seal but a violent fusion, where the entity's obsession with eternal wandering and endless disorientation became the operating principle of the artifact. This Chaos Walker does not scream; it whispers. Its consciousness is not a beast in a cage but a poison in a well. It does not seek to escape, for it has no sense of a destination. It seeks only to *share* its state—to drag all who fall into the sword's domain into the same eternal, directionless maze it inhabits. The wielder must constantly suppress this pervasive will with their own Dao Xin (道心, heart-mind of the Dao), or risk their own perception of reality becoming unmoored.

Mastery of the Sword of Immortal Entrapment is not a bond but a constant threshold test. The Ren Zhu (认主) ritual requires the wielder to attune their own spiritual perception to the sword's chaotic space-time, a process that leaves permanent, disorienting echoes in the wielder's mind. The sword does not drain blood or life force in a simple transaction; it demands a foothold in the wielder's consciousness. The sword's characteristic of being indiscriminate—its Entrapment Domain does not distinguish friend from foe—is its primary threat. A wielder who cannot maintain perfect, pinpoint control of the sword's activation will themselves be trapped within the spatial-temporal currents of their own weapon. The true danger is not a sudden, violent Shi Zhu (噬主) event, but a slow, creeping fragmentation of the wielder's ability to perceive real space and time from the sword's fabricated labyrinths. The tradition treats this not as a contract that can be broken, but as a burden that must be carried with absolute mental discipline.

Only one stable wielder is recorded for the Sword of Immortal Entrapment: **Tongtian Jiaozhu**, the master of the Jie Sect and the forger of the Zhu Xian Si Jian. He wielded the sword as a component of his legendary Immortal Slaying Formation, using it to entrap the armies of the Three Realms during the investiture wars recorded in the *Fengshen Yanyi* (《封神演义》). Tongtian Jiaozhu himself did not fall to the sword's backlash, for his own cultivation was so profound that he could control the entire formation. The tradition does not record a second wielder who survived its use. The sword's nature makes it practically unusable as an individual weapon, and any attempt by lesser beings to wield it independently has only been recorded in theoretical warnings. Within the context of the formation, the sword's burden was shared, and its power was one part of a greater system.

The most famous recorded use of the Sword of Immortal Entrapment is its integral role within the **Immortal Slaying Formation**. When fully activated, the sword did not act alone; its 'Entrapment Domain' wove together with the killing principles of the other three swords, creating a self-reinforcing slaughter matrix. The sword's effect was to freeze the battlefield, preventing any escape and forcing all trapped within to be systematically disassembled by the other swords. The tradition does not specify an exact number of uses or a specific 'cooldown' period, but it is heavily implied that the sword cannot be wielded independently for extended periods. Each prolonged activation permanently crystallizes a patch of 'Entrapment Domain' into reality, distorting the local spatial perception of that area forever. The tradition also warns that sustained operation of the sword's array can trigger a spatial-temporal resonance with the local Di Mai (地脉), causing chaotic time flow in the surrounding region for centuries.

The Sword of Immortal Entrapment is one of the **Zhu Xian Si Jian** (诛仙四剑), a set of four Primordial Slaughter Treasures forged by Tongtian Jiaozhu. It is paired with the Xian Sword (诛仙剑, Sword of Immortal Slaying), the Lu Xian Sword (戮仙剑, Sword of Immortal Slaughter), and the Jue Xian Sword (绝仙剑, Sword of Immortal Extinction). These four swords are not merely companions; they are functional cogs in the Immortal Slaying Formation. The Entrapment sword provides the cage, while the others provide the execution. No specific counter-weapon is recorded, but the formation itself was famously countered during the *Fengshen Yanyi* when four supreme beings (Laozi, Yuanshi Tianzun, and others) each neutralized one of the four swords simultaneously, breaking the array's symmetry.

The Sword of Immortal Entrapment is currently sealed, along with its three sister swords, within the remnants of the Immortal Slaying Formation. After the investiture wars, Tongtian Jiaozhu was forced to disband his sect and seal away his most dangerous treasures. The exact location of the formation's remains is unknown in the current age. The tradition holds that the four swords are inactive, their powers suppressed by multiple layers of Feng Yin (封印). Their future activation would require a being of immense power to break the seals and re-establish the array. The sword itself remains intact but dormant.
