Nature and Structure

The Cosmic Sea is an exceptionally dangerous region of the Source World. Origin Continent powers universally regard it as a deadly zone: explorers face increasing resistance, and even Universe Gods have historically struggled to return once they venture deeply inside 328 406 484.

Within the Cosmic Sea, the three thousand Original Universes resonate with one another and serve as major pillars of a much larger formation. Lin Qingyu determines that these universes are not the formation's core array eyes, implying an even deeper structure beyond his ability to fully analyze at the time 485.

Connection to the Origin Continent

• The Original Universes and their surrounding Cosmic Sea lie toward the edge of the Source World, while the Origin Continent lies at its center; even a correct route requires nearly a trillion years of travel at Eternal True God-level speed 440.
• Origin Continent lifeforms suffer backlash upon entering the Cosmic Sea, with stronger lifeforms provoking harsher resistance 463 477.
• The Cosmic Sea's rejection of Origin Continent intruders is tied both to the Supreme Rule's protection of the World Beast birthplace and to the Rhino Emperor's inheritance formation 542.
• Lin Qingyu, as a lifeform born within the Cosmic Sea, can use his Boundary Breaking Teleportation Technique there without suffering the usual backlash 468 484.

Environmental Mechanics

Chaos Qi Flow and Chaotic Tides

The Cosmic Sea is filled with Chaos Qi Flow, which can nurture many kinds of treasures over long periods. Its abundance is offset by extreme danger and the scarcity of successful deep-sea explorers 477.

When an Origin Continent cultivator enters, the Chaos Qi Flow condenses into chaotic tides according to the entrant's strength.

• Initial tides obstruct forward movement and batter explorers directly 477.
• Once an explorer passes them, the tides pursue from behind and drive the target farther into the Cosmic Sea 477.
• The tides accumulate rather than cancel out, eventually making retreat impossible 477.
• In sufficiently deep regions, the tides can crush space, suppress time-related secret arts, and kill God Kings 484.
• The Original Universe may reinforce this backlash by mobilizing its own origin power against nearby Universe Gods 485 529.

Spatial Restrictions

Ordinary space-tearing and large-scale teleportation methods are generally unusable for Origin Continent experts inside the Cosmic Sea, forcing most explorers to travel by flight 484.

The Boundary Breaking Teleportation Technique can open a route into the Cosmic Sea, but targets may resist being moved and still suffer the Sea's backlash after arrival 484. Lin Qingyu exploits this exception to send Shi Ling and Tian Can into a region where the chaotic tides can kill God Kings 484 485.

External Exploration Formations

The God King Alliance establishes a dedicated Cosmic Sea formation to weaken chaotic tides and guide explorers back before they become trapped 475 477.

• Formation phantoms can reduce incoming tides back into ordinary Chaos Qi Flow near the expedition force 477.
• The formation can forcibly pull God Kings back, provided they do not venture too deeply 475.
• Even with this protection, the backlash becomes more severe as an explorer's life level and strength increase 477 535.

Known Regions and Landmarks

• Universe Boat — One of the original three great dead zones; a damaged top-tier Mechanical Stream treasure capable of devouring Chaos Qi Flow, Small Universes, and dangerous zones for energy after Lin Qingyu repairs it 394 441.
• Qingfeng Realm — A dangerous region resembling a mountain cleaved in half; even True Gods can perish within it 443.
• Liuchong Mountain — One of the original great dead zones, later explored by Lin Qingyu with the restored Universe Boat 407 443.
• Dim Place — The World Beasts' homeland and a region from which they can attempt to enter the Cosmic Sea through multiple routes 415.
• World of Jin — A humanoid object one hundred million light-years across that becomes the fourth great dead zone recognized by the Original Universe's will 407.
• Blockade Lines — Defenses established by Lin Qingyu to seal routes from the dim place into the Cosmic Sea; they suppress and obstruct World Beasts attempting to escape 417 418.

Inhabitants and Explorers

Cosmic Sea Powers

The major factions of the Cosmic Sea largely reside within the Small Universes of their strongest members. This makes enforcing alliances difficult, since these factions have no fixed territorial base comparable to one inside the Original Universe 364.

The Cosmic Sea contains powers from three reincarnation eras, alongside the East Emperor and Purple Moon Holy Land Universes. The Holy Lands are distinct from ordinary factions because they cannot join the Hongmeng Alliance 365 394.

World Beasts

World Beasts originate from the Cosmic Sea and can devour the origins of Small Universes, causing a target's strength to decline dramatically 417 542.

Their attempts to invade are focused on destroying the Small Universes that serve as the foundations of Cosmic Sea powerhouses 416. Lin Qingyu's blockade network and repeated captures force the World Beasts to unite and reconsider direct assaults on the Cosmic Sea 415 416 418.

Origin Continent Expeditions

The Cosmic Sea's danger has not stopped Origin Continent powers from seeking its resources and ancient inheritances.

• The Food Country's Tianqi and Shi Ling lead Mechanical Stream expeditions in search of the Wu Country remnants 477.
• The God King Alliance sends weaker Chaos Masters and Eternal True Gods ahead as scouts, since they trigger less severe backlash than Universe Gods 477.
• The alliance's principal objective is to exploit the Cosmic Sea's resources while locating the Wu Country legacy, including the Wu King Palace and Future Hall 477.

Story Role / Major Arcs

• Small Universe expansion — After becoming a True God, Lin Qingyu determines that his Cosmic Origin-bearing passages cannot expand within the Original Universe and turns to the vast Cosmic Sea instead 329 330.
• Hongmeng Alliance expansion — Cosmic Sea factions seek entry into the Hongmeng Alliance for access to Human Race inheritances, treasures, and a possible path beyond reincarnation 364 365.
• World Beast crisis — World Beasts attempt to leave the dim place and attack the Small Universes of Cosmic Sea powers, but Lin Qingyu's preparations seal their escape routes 415 417 418.
• Universe Boat restoration — Lin Qingyu repairs the Universe Boat, gains its recognition as master, and uses it to absorb dangerous zones and reconstruct Qingfeng Realm and Liuchong Mountain 439 442 451.
• God King conflict — Lin Qingyu and King Wu's virtual consciousness send Shi Ling and Tian Can into the deep Cosmic Sea, where the Sea's tides become the principal threat against them 484 485.
• Universe God breakthrough — Upon reaching Universe God level, Lin Qingyu gains authority over the Rhino Emperor Formation and can suppress the Cosmic Sea's backlash to protect others 543.
