Demon God Myriad Thunder was not the same as the Infinite Devourer and the Lord of the Void. He was one of the first to invade the Spiritual Realm, and he was a sealed Demon God that held the Heaven Devouring Mystic Technique.

Demon Supremacy Wish Fulfillment's Heaven Devouring Great Dao sublimated from this technique. If you obtain it, the benefits are endless, allowing you to advance your realm quickly. You could even devour a Heavenly Dao and break through the Netherheaven bottleneck!"
"Break through Netherheaven?!"
Fang Yuan's interest was piqued.
