Half an hour later, Xu Huo got some not entirely unexpected answers. Firstly, Primeval Stones can definitely be destroyed; the difficulty depends on the type of Primeval Stone. Generally speaking, the better the quality and the higher the level of the Primeval Stone, the harder it is to destroy. But as of today, with the development of technology in the game world, no Primeval Stone is indestructible; it mainly depends on whether one is willing to do it. After all, Primeval Stones with special attributes like the "Time Origin" are quite rare, and their preservation value far exceeds that of using them to make props.
As for the pollution claim, no one mentioned it. To put it plainly, a Primeval Stone is a type of mineral with a more stable structure, and it's hard to pollute it like flora and fauna, unless you cover it with special pollutants on a large scale.
Perhaps that Rank-A Player was talking about the latter method.
