Edgeless

Biodata

Power Progression

Appearance

• Original form: A roughly seven-chi, pitch-black giant saber with an unsharpened edge. Its early hilt is wrapped in ox sinew 23 25.
• Surface details: Matte black metal, dark-red patterns near the edge, and visible hammering marks along the spine. Dark-gold veins appear during Sha Qi absorption and intense rune activation 76 124 170 185.
• Reforged form: Seven chi and seven cun long, with a two-foot-wide blade, a three-inch-thick spine, and an integral handle and guard. The handle is a foot and a half long; the blade narrows toward a thick, acute point 156 158.
• Cutting edge: Clearly defined after reforging, but deliberately thick rather than exceptionally sharp. Its purpose is to concentrate the saber’s immense force while resisting chipping 156.
• Giant transformation: Lengthens, broadens, and thickens as it devours weapons, developing a curve along its spine and a dark-golden halo along its edge 323.
• Later appearance: Retains an unadorned, dark exterior despite its increasing power. One later description notes no visible Spirit Runes, gems, or decorations 466.

History

Forging and the Northern Border

Qin Tiexin forged Edgeless at his family’s smithy in Ink City, exhausting himself to the point of unconsciousness. When attempts to sharpen it produced little more than shallow scuffs, he sensed the metal’s reluctance to lose even a small amount of itself. Remembering his master’s teaching that the best saber was the most suitable rather than the sharpest, he named it Edgeless 23 153.

At Xinyang Pass, Edgeless accompanied Qin through military training, his first killing, battles against Northern Di soldiers, and the capture of Yelü Hongshan. Shi Meng taught him to transmit strength from his feet through his body into the blade instead of merely smashing with brute force. Qin subsequently developed the rough forms Mountain Collapse, Sever the Flow, and Return to Stillness 52 153 718.

Awakening and Reforging

After crossing Spirit Severing Mountain, Qin began sensing Edgeless’s hunger. Feeding it became a continuing expense alongside his own cultivation and body tempering. Its ability to absorb spiritual metals increased its weight without necessarily changing its size 73 76 89 92.

By the aftermath of the grand competition, Edgeless was broken in two. Preparing to repair it forced Qin to recognize flaws in his original workmanship: an overly forward center of gravity, an excessively thick hilt, slow changes of direction, and an edge prone to chipping against hard objects. His task gradually became one of reshaping his familiar saber to suit him better, rather than simply joining its broken pieces 145 150 153.

Luo Ling made the reforging Qin’s entrance examination, with herself and Wu Zhen providing support rather than taking over. Using Azure Nether Spirit Fire, a twelve-hundred-jin hammer, and essence from a Primordial Molten Core, Qin rebuilt Edgeless and inscribed a new set of three Spirit Runes. The finished saber possessed a balance and grip that felt like an extension of his body 153 155 156 158.

The Blood Pool Transformation

During the battle with True Person Xueying, Qin’s [Weapon] rune touched Edgeless’s hilt. The saber began drawing weapons from throughout the cavern, consuming them to enlarge and repair itself. Even being cut completely in two failed to stop it: the detached portion fragmented, flew back, and merged with the remaining blade 323.

Afterward, Qin recovered Edgeless in its familiar shape, but with greatly increased weight, no remaining damage, and far clearer emotional responses. Subsequent tests established that its weight rose alongside his physical strength, precisely matching his maximum left-hand strength 328 345 362.

Return to Xinyang Pass

Years after its first battles, Edgeless carried Qin and Sun Aji toward Ink City. When they paused above Xinyang Pass, it began humming and trembling. Qin associated the reaction with the battlefield where its blade had first drawn blood and where many of his comrades had died 718.

Abilities & Skills

Growth and Adaptive Weight

Edgeless develops a growth-type property after the blood pool incident, adjusting its weight as Qin becomes stronger 345 362.

• Exact strength matching: Measured at 72,000 jin and later 103,000 jin, each time equaling Qin’s tested left-hand strength 362 434.
• Adaptive handling: After its transformation, its weight, balance, and grip feel tailored to Qin’s current condition 328.
• Uncertain ceiling: Qin does not know whether it can continue growing indefinitely. Such growth properties are normally associated with much higher-grade treasures and are rare even among Spirit Artifacts 362.

Metal and Weapon Devouring

Edgeless assimilates external metals into its own black substance 89 153.

• Density increase: Absorbing Crimson Heart Copper raises its weight without changing its volume 89.
• Reforging compatibility: Absorbs the mixed spiritual materials of the Primordial Molten Core; heat and repeated hammering accelerate the process 155 156.
• Mass weapon absorption: Under the conditions of the Xueying battle, draws in intact weapons, broken weapons, and Law Artifact remains from across the cavern 323.
• Combat regeneration: Consumed weapons replace missing material and close fresh wounds, including severe cuts inflicted by Xueying’s higher-grade Law Treasure saber 323.
• Limit: Its hardness does not make it indestructible. Higher-grade weapons can cut through it, even though continued feeding can repair that damage 323.

Sha Qi Absorption and Purification

Edgeless consumes Sha Qi from Demon Beast materials and members of the Devil Race 170 217 242.

• Artifact-material cleansing: Removes baleful intent from fangs and spirit bones while leaving their useful spiritual power intact 170 210.
• Self-repair: Uses absorbed Sha Qi to mend cracks and stabilize damaged internal pathways 210.
• Defensive counter: Devours Blood Sha Qi on contact, opening a passage through the winged man’s protective barrier rather than merely dispersing it 217.
• Repair requirement: Three Foundation Establishment Demon Beast spirit bones do not completely restore its accumulated damage; Qin estimates that at least five more comparable bones are needed 210.

Blood Bead Condensation

Edgeless can produce red-black Blood Beads from certain devils’ absorbed Sha Qi 231 242.

• Documented sources: Demon General-level devils and Blood Devils 242.
• Lesser devils: Other Devil Soldiers provide Sha Qi for repairing the blade but do not produce Blood Beads, even at high rank 242.
• Value to Qin: The beads contain pure Qi and Blood essence without pill poison or side effects, making them especially useful for his body refining 231.

Spirit Runes

The original rune set was destroyed when Edgeless broke. Qin replaced it with three interwoven runes during reforging 154 158.

• The three runes form a simple resonance without conflicting, but do not constitute a full Spirit Rune Array 158.
• Activating them raises the reforged saber’s weight from 6,300 jin to over 7,000 jin during the winged man battle 217.
• Edgeless’s metal-devouring behavior predates the inscription of Spirit Devouring 89 154.

Heavy Saber Combat

Edgeless complements Qin’s strength-based fighting style and the Heavy Mountain Saber Technique 146 185.

• Concentrated impact: Mountain Shattering destroys the palace guardian puppet’s core after Qin and Liu Qing create cracks through extreme heat and cold 185.
• Armor and shield breaking: Splits a Buddhist tower shield approaching Upper-Grade Law Artifact quality and kills its bearer in the same stroke 467.
• Thrown attacks: Its 150,000-jin mass helps strip away Xuanli’s protective bone powder, exposing golden bones whose Buddhist power weakens him 540.
• Blood-mist interaction: In giant form, interferes with Xueying’s mist transformation and drains nearly twenty percent of his Qi and Blood in one major blow 323.
• Limits against defenses: Initially cannot overcome the Ice Devil General’s armor without the Wind-Rending Dagger opening a breach. It also passes harmlessly through the Void Spirit Python’s transparent form 252 515.

Training and Flight

• Body-tempering weight: Makes the Old Qin Household Body Tempering Method more than ten times as exhausting as empty-handed practice. Its load exposes poor posture and inefficient force transmission 25.
• Technique demands: Improperly channeling its weight during Suppress the Mountain dislocates both of Qin’s arms and strains their muscles 92.
• Flying transport: Can hover and carry both Qin and Sun Aji over long distances, including the journey toward Ink City 718.

Sentience and Temperament

Edgeless’s earliest responses are faint impressions rather than speech: reluctance to lose material, hunger for spiritual metals, and apparent pain at its broken blade. After the blood pool transformation, Qin senses a clearer sliver of consciousness and unmistakable affection 23 73 150 328.

Its emotions are conveyed through warmth, vibration, humming, and the connection between their minds. It reacts warmly to being taken out after confinement, expresses joy when Qin grips it, and later shows displeasure when he transfers it from his left hand to his newly attached right hand 345 419 499 718.

Relationships

• Qin Tiexin — Creator, owner, and bonded wielder. Their compatibility develops through forging, battle, reforging, and prolonged use; Qin regards Edgeless as his most dependable companion 146 158 207 328.
• Luo Ling — Guides Qin’s redesign, supplies Azure Nether Spirit Fire, and evaluates the completed saber’s structure and grade 153 155 158.
• Wu Zhen — Examines the Primordial Molten Core, supports Qin during reforging, and confirms that the finished weapon has no problems 153 155 158.
• Shi Meng — Teaches Qin how to control Edgeless through whole-body force transmission rather than uncontrolled strength 52.
• Sun Aji — Rides on Edgeless with Qin and imitates him by stroking its blade to soothe it above Xinyang Pass 718.
