Deity Fusion was nothing new to Isaac. He had mastered it soon after the technology for virtual deities emerged.
He had originally developed it to try to overcome the upper limit on virtual deities' strength. Unfortunately, although fusion worked, it did not break that ceiling as he had imagined. It merely turned a single divine authority into multiple divine authorities.
But after he took control of actual gods, this technique became useful again!
Using the power of [Sage of the Gods] as a medium, he could fuse multiple gods under his control, greatly enhancing their strength. Unfortunately, perhaps because virtual deities and true gods differed somewhat in essence, fusion raised their power ceiling but did not grant two divine authorities as Isaac had hoped. Instead, one divine authority became the core, with the others partially incorporated into it.
In previous experiments, the God of Gourmet's [All Things as Food] had served as the core, primarily to accelerate his growth and explore further possibilities for that divine authority. In battle, however, the Lord of Billions of Flesh and Blood naturally took center stage.
Hence the name, God of Billions of Gourmet!
His divine authority changed from [Flesh and Blood] to [Blood Feast], gaining several extraordinary abilities on top of its original capabilities. Isaac's favorite among them was an ability called "Self-Consumption"!
Its effect was simple: he could devour the flesh he had created to temporarily increase his strength. The Lord of Billions of Gourmet knew perfectly well how powerful Grell was, so he activated it without much hesitation as he charged. His aura contracted, then surged outward, temporarily breaking through to Upper Sixth Tier!
"Bring it on!" A sharp gleam flashed in Grell's eyes. Excitement spread across his face as he swung his sword and charged at the Lord of Billions
