Merlin pushed with both hands. The wind howled, and anyone could clearly see that the flames and thunder were in the storm, gradually fusing together.

The colossal shockwaves immediately sent the Greater Demon flying but this time, he had no way of standing up again. His entire body was fragmented in the blast, and torrents of blood flowed out, and the soil on the ground was stained a deep red.

Merlin appeared abnormally calm. He shut his eyes lightly, still carefully recollecting how it had felt when he had fused three spells earlier. He wanted to hold on to this feeling. It was key to fusing three types of spells.
