Mr. Door

As Trissy recited the words, the gems around her emitted cracking sounds as they shattered into powder and floated up.

They shimmered with red, blue, green, or resplendent light before rapidly gathering into a torrent that surged towards the candlelight on the altar.

At the same time, strands of hair that had been burnt inside the cauldron joined the process.

The fire began to expand and interweave with each other, turning increasingly dark, as if it was an illusory door that led to other worlds.

Trissy immediately felt the surrounding temperature drop rapidly, as though countless dangers were seeping out of the fire.

A sentence flashed across her mind. It was a reminder from Gehrman Sparrow:

"Be careful of Mr. Door."
