Custom Made Demon King

The cold icy wind howled, and a blizzard raged in the depths of the snowy mountains of Xiansai. Dense snow and cold air blocked the spread of light, allowing the depths of the snow mountains to maintain visibility for a long time. The -70°C climate made this place a forbidden zone for mortals. Only the ice and snow demons and monsters living here could move freely.

On the highest mountain in the depths of the mountains, there was a dark hole that looked out of place under the backdrop of white snow. Even the blizzard couldn't cover the hole because a gray mist always enveloped it.

If someone could pass through the mist into the cave and then follow the cave tunnel for about a kilometer, they would find that it was another world inside. A black palace of nearly ten thousand square meters had been built in the cave, and all kinds of Gothic-style sculptures stood here, surrounding a huge throne condensed from black ice.
