A Hundred Years’ Time Limit

Merlin looked at Sea of Purgatory Fire which he had recently constructed. It was not burning with white flames, indicating that Fiery Collapse was not fused with the spell.

For Pandora Demon Ability, Fuse Earth and Darkness Heart, they would merge with the spells right away. When the spells were cast, the power of the Pandora Demon Abilities would be automatically activated.

After ruminating about this for a moment, Merlin called upon Fiery Collapse as before.

The flames of Sea of Purgatory Fire, which were initially raging fiercely, now turned white. Merlin was slightly taken aback when he saw this transformation, which meant that Fiery Collapse had combined with Sea of Purgatory Fire.
