A general of His Majesty Void Mask brought the problem of keeping the poor of Dar Territory warm to a close.
Naturally, Sui Xiong did not need to chop down trees. After learning the situation, he wielded divine power and directly fetched some crimson stones from the Plane of Fire, stones that continuously radiated heat.
These stones could absorb heat and release it in cold environments. On the main plane, quite a few fashionable wealthy merchants used them for warmth in places where they were staying temporarily. Compared to using magic for heating, their cost was slightly lower. Their only drawback was that they were rather dangerous—these stones were unstable and could easily burst, scalding people.
The main plane did produce such stones, of course. They generally appeared inside volcanoes or in underground lava. Since they were troublesome to mine and not especially valuable, their output was very low. The amount Sui Xiong had gathered this time was perhaps greater than what normally appeared on the market over ten years.
Using these stones, known as "Hellrock Ore," for heating was a technical job. Without sufficient skill, not only would one fail to get warm, one might scald oneself instead. Sui Xiong happened to know the technique, because he had once seen merchants in the territory of the Merchant Faction of the Gold Coin Federation using these things for heating.
Their method was to bury the stones underground, wrap them in a thick layer of ash, then cover them with another layer of soil before laying wooden boards on top. After some time, the heat would seep up through the boards, making an entire large room warm and cozy.
Mm, it felt just like underfloor heating.
There were several key points to this technique. First, the soil used to bury the
