Ancestral Master Eon Sea

Ancestral Master Eon Sea is a historical invincible Creation Supremacy, creator of the Eon Sea Fiend Body, and rival of Ancestral Master Archean. His disagreement over how humanity's unified sect should be governed leads to civil war and the founding of Eon Sea Sect, whose surviving legacy Meng Chuan later returns to Archean Mountain. (Chapters 377–396)

Biography

Rivalry, schism, and preserved lineage

Eon Sea and his senior brother Archean become the strongest disciples of Archean Eon Sect and both reach invincible Creation strength. Eon Sea views the other man as his only true rival, but opposes Archean's plan to loosen the sect's monopoly and permit outside human factions. Supported by other Supremacies, he fights a civil war and loses after Archean becomes an Imperial Lord. (Chapter 390)

Archean does not destroy the defeated faction. He divides the lineage into Archean Mountain and Eon Sea Sect, allowing Eon Sea to choose three cornerstone treasures. Eon Sea spends the rest of his life competing through the new sect and leaves instructions that Archean's lineage should survive even if Eon Sea wins. He dies at the end of his lifespan without becoming an Imperial Lord because his Essence Soul does not meet the requirement. (Chapters 390 and 394–396)

Appearance and personality

His preserved sect-master image shows a thin man who smiles while recounting his history. He describes himself as exceptionally intelligent, competitive, and dismissive of many seniors, yet acknowledges Archean's superior cultivation and refuses to frame their conflict as personal extermination. Because the scene is a legacy recording, it reports his chosen final account rather than a live present-day interaction. (Chapter 390)

Abilities and cultivation

Eon Sea reaches invincible Creation strength and can defeat ordinary Supremacies above his formal level. He creates the transcendent-grade Eon Sea Fiend Body and attains high Battle God Pagoda and Heart Sea Palace rankings. His technique and body remain below Archean's eventual achievements, and failure to raise his Essence Soul prevents the Imperial Lord breakthrough despite sufficient other attainments. (Chapters 378, 380, and 390)
