Why are the stones in Millstone Park black?

The stones in Moshi Park are black, because these stone mountains contain a lot of minerals.

The stones in Millstone Park are black because they contain a lot of minerals. The surface of the mountain is also bare, which is in sharp contrast with the surrounding green hills. The magic of the stone forest here is that it will change into different colors with the weather. The air is light gray and light blue when it is dry, and light black or even two colors when it is wet. This is because inkstone contains calcium salt, and the crystal water contained in it is affected by air humidity.

The mountains in Millstone Park are continuous. The vegetation on the mountain is not dense forest, but low shrubs and grasslands, forming a grassland-like mountain range. Its disadvantage is black, like towering carbon rods, rather than the common color of mud or stone. These black stones form a unique stone forest called Magic Stone.
