Fuxi’s Zither

天音推衍之琴 Fuxi’s Zither of Heavenly Music and Divination
器属类型: 法则化音律法器 Musical Artifact of Law Manifestation
Artifact Tier: Primordial Divine Armament (太古神兵)
Current Holder: Unknown; last recorded wielder was Fuxi himself.
Current Status: Silenced, its physical form is believed to have faded into the patterns of the He Tu (River Chart).

Fragments of its tonal diagrams are recorded in the *Shi Yi Ji* (《拾遗记》), the *Tai Ping Yu Lan* (《太平御览》), and the *Shu Yi Ji* (《述异记》). The primary textual references are the *Zhou Yi·Xi Ci Zhuan* (《周易·系辞传》) and the *Shan Hai Jing·Hai Nei Dong Jing* (《山海经·海内东经》).

Fuxi's Zither is inseparable from the figure of Fuxi, the primordial sage-king and inventor of the Eight Trigrams. Its internal structure is a direct acoustic embodiment of the He Tu (River Chart) and the Luo Shu (Lo Script), the foundational diagrams of Chinese cosmological order. Understanding the zither requires understanding the metaphysical weight of those diagrams. The zither’s fate is also tied to the aftermath of the Great Disconnection (Jue Di Tian Tong), as its power predates the separation of the Three Realms.

Fuxi’s Zither is a Primordial Divine Armament forged in the Honghuang Era. Its core power is the ability to directly manifest cosmic law through musical tones. By plucking a specific string, the player causes the corresponding elemental principle—wind, heaven, earth, thunder, or the deepest logic of the Dao—to resonate and interfere with the physical world. A single stroke of the “Wind” string can summon a hurricane across ten thousand li. A pluck of the “Heaven” string can shift the positions of stars and invert the flow of time. The “Earth” string can alter mountain ranges and reverse the course of rivers. The zither’s most fearsome ability is the “Shen Yi Xi Hun” (Soul-Washing Divine Intent): the player does not need a written score. Whatever object or law the player visualizes in their mind, the zither automatically translates that mental image into a corresponding melody, using the target’s own existence-law as the musical template. If one can master the highest, forbidden string—the “Dao Yin” string—the player can, within a single musical phrase, play out the causal chain of the next hundred breaths of time, allowing the listener to experience events before they occur. No cultivation level is stated as a minimum requirement, but the tradition holds that only one whose mind is a perfect mirror of the Dao can survive a single stroke of that highest string.

The zither’s strings were woven from two primordial materials. The first was the Di Mai Zhi Si (Earth-Vein Silk), harvested from thousand-year-old ice silkworms that lived only at the peak of Mount Kunlun, where the mountain’s dragon pulse surfaced. The second was the Pi Li Zhi Si (Thunderbolt Silk), forged from lightning bolts tempered in Nine-Heaven Tribulation Thunder. To gather these materials, Fuxi paid in his own flesh. He climbed the ice cliffs of Kunlun with bare hands, and the cold from the earth-vein silkworms froze the marrow in his fingers. He reached into a live thunderstorm to catch a bolt of lightning as it split the sky, and the electrical discharge carved the flesh from his palms down to the bone. The zither’s body was carved from a single piece of Kunlun jade that had absorbed the resonance of the first thunderclap after Pangu’s death. Where Fuxi harvested the ice silkworms, the silk-gorge collapsed and became a petrified gorge of dead ice, never again producing silk. The mountain peak where the lightning was caught was split in two and the halves never regrew grass.

Fuxi’s Zither does not possess a Qi Ling in the usual sense—no sacrificed human soul was sealed within its body. Its animating force is something far more impersonal: a Law Echo (Fa Ze Can Xiang) of the Eight Trigrams (Ba Gua) themselves. The zither’s core array is a direct inscription of the River Chart (He Tu) and the Lo Script (Luo Shu), the original diagrams of cosmic order. The sound produced by the strings is not music but the audible vibration of the Eight Trigrams moving in sequence. Because no sentient soul was sealed inside, the zither has no desire, no hunger, and no spontaneous malevolence. But this also makes it inhumanly indifferent. Its will is the will of the calculation. It does not care if the player lives or dies. It will produce the correct tone even if that tone resonates the player’s own spirit into dissolution. Those who examine the zither’s internal structure report that plucking it feels like reaching into the mind of the universe while it is computing its own laws.

Fuxi’s Zither does not require a blood-bond or a soul-opening recognition ritual. Its master recognition is exclusively intellectual: the zither accepts only a player who already understands the principles of the Eight Trigrams at their deepest level, and whose mind can hold the full pattern of the He Tu and Luo Shu in simultaneous focus. The tradition states that the zither tests each player by vibrating the strings of the player’s own skull: if the player’s mental pattern does not match the pattern of the zither’s internal array, the dissonance shatters the player’s cranium and eardrums, and the player dies instantly. The real cost of sustained use is not blood but memory. Each time the zither is played, the player permanently forgets one fragment of their own life. The Forgotten Tones extract the player’s memories as fuel for the manifestation of law. The longer a player uses the zither, the more they forget. Fuxi himself, after finishing his great divination of the cosmos, could no longer remember the faces of his own parents or the sound of his own name. This is not an accidental side-effect but an inbuilt thermodynamic principle of the artifact: the cost of manifesting a law of reality is the payment of an equal quantity of personal reality.

Only one stable wielder is recorded in the orthodox tradition: Fuxi himself, the progenitor of divination and the inventor of the Eight Trigrams. He used the zither to decode the patterns of the He Tu, to map the movements of celestial bodies, to pacify the floods of the early Honghuang Era, and to establish the basis of Chinese cosmic law. No successor is known to have successfully played the zither after him. The few who attempted it without Fuxi’s level of comprehension either died instantly from cranial resonance failure or survived a single pluck only to be driven permanently mad by the flood of unprocessed cosmic information. Fuxi’s own end is recorded not as a death but a dissolution: as he played the zither to its final silence, he forgot himself entirely. The tradition says he merged with the pattern of the He Tu, becoming a principle rather than a person. The zither’s silence is a form of mercy.

The zither’s most famous recorded activation is Fuxi’s original performance that produced the Eight Trigrams themselves. As he plucked the “Heaven” string, the stars reorganized themselves into their current positions. As he plucked the “Earth” string, the rivers of the central plain changed course into their present channels. The full recitation of the He Tu and Luo Shu is said to have lasted for three days, during which time the entire world was reshaped from its primordial chaos into the stable geography remembered in the Shan Hai Jing. There is no documented upper limit to the zither’s power or a known number of uses before destruction, but the tradition emphasizes the memory cost as a soft limit: after a certain number of performances, the player will have lost so much personal memory that they become functionally a living corpse—still alive, still holding the zither, but no longer a person.

The zither is directly linked to the He Tu and Luo Shu diagrams; some versions of the myth treat the zither as the acoustical mirror of those visual patterns. No paired or counteracting artifact is recorded. The zither is not a remnant of any higher weapon.

Silent and masterless. Its physical form is believed to have dissolved back into the patterns of the He Tu after Fuxi’s final performance. Some traditions hold that the zither still exists as a latent acoustical field within the River Chart’s pattern itself, waiting for a player whose mind can once again hold the full calculation. No known person has successfully retrieved or reawakened it.
