Nature and Composition

Mountain Sea consists of two vast aspects: the Infinite Sea and Above Mountain. In its earliest state, mountain and sea stood side by side; their eventual fusion reshaped the nature of time, possibility, and life within them. 1734 1735

It is not static terrain. Mountain Sea continually changes as possibilities develop, disappear, and are altered by transcendent beings. The Other Shore regards it as an “Experiment Field” into which new variables and parameters can be introduced. 1609

Mountain Sea possesses its own obscure will. It can react against beings it considers parasitic or hostile, and Li Fan warns that any attempt to “burn mountains and boil seas” must account for its retaliation. 1604

Appearance

Mountain Sea is perceived as an immeasurable union of sea and mountain rather than a humanoid being.

• Infinite Sea — an immense sea that gives rise to and destroys innumerable possibilities and civilizations. 1602 1735
• Above Mountain — the towering counterpart to the Infinite Sea, toward whose summit living beings instinctively strive to ascend. 1735
• Mountain-Sea fusion — the two aspects gradually eroded and merged until they became the continuous Mountain Sea known in later ages. 1735
• Civilizational traces — the rise and fall of civilizations leave imperceptible ripples upon the sea and marks upon the mountains. 1713

History

Origin and Early Evolution

Before the Mountain Sea of later ages, Mountain and Sea were engaged in the prolonged consumption of the True God. This process occurred in a spacetime without conventional passage of time; once digestion was complete, the two evolved into Mountain Sea. 1763

In the primordial era, Mountain Sea maintained stricter laws and a stable, harmonious order. When it collapsed, it swept up creatures in a storm of assimilation; survival depended on becoming part of Mountain Sea itself. 1734

A gaze from beyond disrupted Mountain Sea's belief that it could preserve eternity. Time began to flow, and living beings within the Infinite Sea started attempting to ascend Above Mountain. 1735

The Three Saints' Era

Lian Shan Saint became the first being to ascend Above Mountain. Though he perished after sensing the gaze beyond Mountain Sea, he attained enlightenment and opened a path for later beings. 1735

Following Lian Shan, Gui Hai and Tai Yi were born. The Three Saints guided living beings toward linking mountains, crossing seas, and wielding Mountain Sea's power. Their emergence also made Mountain Sea increasingly connected to the civilizations that had originally been separate from it. 1735

Dao Obliteration and Fragmentation

Life within Mountain Sea accelerated its fusion by acting as a catalyst. At the height of this prosperity, Dao Obliteration emerged without a known origin and steadily grew into a force capable of confronting Mountain Sea. 1736

Dao Obliteration cut the continuous Mountain Sea into innumerable fragments. While internal veins and patterns preserved a hidden connection, its inhabitants became divided across layers of time, with diminished strength and damaged memories. 1736

Reconnection

The Saints formed chains within the Eternal Silence Void Realm to stabilize a Mountain Sea phantom projection. Because the projection was too fragile to accept direct Sage intervention, they had to preserve history's original course while hastening its key events. 1686 1687

Li Fan and the Saints eventually reconnected Mountain Sea, forcing back the Void Realm and allowing the phantom to become real. The restored Mountain Sea also returned memories and powers from the previous Mountain Sea to the Sages. 1693

The re-alliance restored one hundred thousand years of Mountain Sea history, though the reborn stretch differed from its former state and altered some downstream possibilities. 1723

Awakening

Li Fan later used remade Dao Obliteration to breach Mountain Sea and seize a fraction of its essence for the Dao One Mountain Sea Chart and the Mountains and Seas Boundaryless Stele. 1753

When the Boundaryless Stele disappeared, cultivators above the True Immortal realm rapidly fell to mortality or perished. Mountain Sea then awakened, regarding Li Fan as an existential threat and turning its forces against him. 1757

Abilities & Properties

Fusion and Assimilation

Mountain Sea's fusion is an overarching historical process that transforms both the world and the beings within it.

• Fusion cannot be stopped or reversed even by wielding Mountain Sea's own power, according to the conclusions of the Dark Dynasty's Mountains and Seas Priests. 1603
• To life born within it, fusion resembles annihilation; in truth, it is a transition into a higher form of energy beyond their understanding. 1603
• During collapse, Mountain Sea can absorb creatures into itself. 1734
• Lifeforms within Mountain Sea can accelerate the fusion process by serving as catalysts. 1736

Possibility and Evolution

Mountain Sea continuously produces, changes, and eliminates possibilities.

• Civilizations repeatedly rise from the Infinite Sea, explore Mountain Sea, and are destroyed during its upheavals. 1602
• Different stages of Mountain Sea's growth produce fundamentally different possibilities, likened to growth rings. 1592
• Its changing state prevents all true meanings of transcendence from ever being permanently exhausted. 1609

Great Dao and Sainthood

Mountain Sea provides the foundation for paths that can elevate beings to Saint-level existence.

• Lian Shan Saint's ascent created a path for later beings to pursue the summit of Above Mountain. 1735
• Li Fan attained sainthood by shaping a projection through Mountain Sea, describing his method as “observing all mountains and seas.” 1710
• Li Fan's attainment granted him Mountain Sea's form, but not the spiritual essence held by Saints such as Lian Shan and Gui Hai. 1710
• The Mountains and Seas Boundaryless Stele preserves ancient Great Daos and assists newly certified Cosmic Cycle Saints in consolidating their Dao paths. 1697

Self-Defense and Rejection

Mountain Sea instinctively resists external interference and can respond to threats.

• A Mountain Sea phantom projection may reject Sage-level external force because Sages stand on a level comparable to Mountain Sea itself. 1687
• Its awakened state identified Li Fan as an enemy after he attacked and stripped away part of its essence. 1753 1757
• Dao Obliteration's fragmentation greatly weakened Mountain Sea's inhabitants, but internal veins and patterns retained a concealed connection between its pieces. 1736

Relationships

• Infinite Sea — One of Mountain Sea's two foundational aspects; it births possibilities and civilizations before joining with Above Mountain. 1602 1735
• Above Mountain — Mountain Sea's other foundational aspect; living beings instinctively seek to climb it, and Lian Shan Saint was the first to ascend it. 1735
• Lian Shan Saint — First ascender of Above Mountain and one of the Three Saints who guided Mountain Sea's later development. 1735
• Gui Hai and Tai Yi — The remaining members of the Three Saints; alongside Lian Shan, they fostered paths of linking mountains, crossing seas, and wielding Mountain Sea's power. 1735
• Dao Obliteration — A destructive force that severed Mountain Sea into countless fragments and erased possibilities. 1736
• Li Fan — Reconnected Mountain Sea with the Saints and attained sainthood through its projection, but later attacked it to seize essence for his own treasures. 1693 1710 1753
• True God — Was consumed by Mountain and Sea during the Divinity Division; the completion of this digestion produced Mountain Sea's later form. 1763
