Aur took a deep breath, carefully controlling the fire beneath the furnace, his crimson eyes glowing with a pattern of five circles, the centre one larger than the rest.
After keenly sensing the changes in the furnace, he immediately heaved a sigh of relief.

Following this, Aur began to carve intricate patterns in the floor using chalk, while maintaining a low heat around the furnace. These patterns were all similar to the once he drew when he previously was preparing the potion.
