The story initially focuses on the rise of the main world. The Chaos Sea will be introduced later, so please be patient.
The Chaos Sea has stretched across the ages, nurturing billions of multiverses. At its heart lies the Origin's myriad Great God Worlds. Lin Yuan's side of the multiverse, born from the Primordial Ancestral Realm, rises to prominence. Bearing eight Source Seals, he slays an Evil Lord in the Hongmeng Realm and unexpectedly awakens the divine will of the First-generation Great Luo. Only then does he learn his fate: gather the twelve Source Seals forged from the First-generation Dao Fruits and attain the supreme Great Luo Dao Fruit of the Primordial World.
A Great Luo is one and all, all and one. To attain the Dao is to draw together every parallel incarnation across the Origin's entire multiverse within the Chaos Sea, unifying the myriad selves, transcending the river of time, and remaining untouched by karma. Starting from his own multiverse, Lin Yuan seizes counterfeit seals and gathers the true ones, then crosses the Chaos Sea as a Quasi-Great Luo. He allies with Shi Hao and Ye Fan, Xiao Yan and Luo Feng, Wang Lin and Bai Xiaochun, and fuses the myriad paths of the Emperor's Wilds, Hongmeng, and Burning Heaven into one. He battles the Evil Lords, Evil Marshals, and Evil Venerables under the Fallen Luo, crushes the army of the Evil Source, gathers all the myriad selves across the Origin's multiverse, and rises to become a Great Luo Dao Ancestor.
In the ultimate showdown at the heart of the Chaos Sea, Lin Yuan faces his mortal enemy, the Fallen Luo: a Great Luo Dao Ancestor on the same level as the First-generation, corrupted by evil for ten thousand years. The twelve seals unite, summoning the phantoms of the First-generation and the Origin's myriad Great God Laws. With one sword stroke, he destroys the Evil Source. He then fuses with the origin of the Chaos Sea and attains the Chaos Dao Venerable, radiating his own Dao throughout its billions of multiverses. His Dao blesses all living beings, evil is eradicated forever, and he establishes the supreme, eternal order of the Chaos Sea.
Not bad, worth a look
