The Great Dao's voice sounded softly, and as consciousness awakened, he learned his name was Mo Yuan. His soul had been reborn in an innate World-Destroying Black Lotus, bringing it to life.
Just after he was born, Rahu used soul-searching magic to probe his origins, and unexpectedly glimpsed the future: his defeat and death in the Dao-Demon War.
Rahu: “Now that you know how things end, why not defy fate and change your destiny?”
Mo Yuan: “Let us swear by the Dao's decline and the Demon Dao's rise. We shall become sworn brothers and share the Great Dao.”
The two swore brotherhood at Mount Sumeru and cultivated the foundations of the Demon Dao together. When the Dao-Demon War ended, Rahu burned up his own Dao body, exploiting their sworn-brother bond and the Great Dao oath to secure a benefit: he locked in Mo Yuan's deathless, indestructible nature.
After that, Mo Yuan traveled the Primordial World, gathering scattered remnants of demonic cultivators and secretly rebuilding the Demon Sect's power.
Hongjun: “With all the sages gathered, how can we eradicate the Demon Dao from the world?”
Mo Yuan: “The Great Dao endlessly cycles. Demons will never be extinguished.”
The Primordial World changed with Mo Yuan's arrival, and the Primordial World grew stronger and stronger.
From then on, Mo Yuan ran rampant through the Primordial World for ten thousand years, watching the Witch-Demon War, the Investiture of the Gods, the Journey to the West, and the Immeasurable Calamity unfold. He commanded all demons, free and deathless.
This pig's foot is a bit of a loser, greedy for money, lustful and selfish. I still like Da Luo, who is firm in his Taoism and will prove his eternal certification. This looks like watching martial arts.
