The hardness of rocks varied. The rocks in this Mountain Cave were exceptionally tough; even if a group of Lower Gods besieged it, they would need quite some time to break through.
To obtain the stubborn stone inside as quickly as possible, they could only enter in person.

The black mist within the cave was highly unusual—extremely dense and heavy, making it difficult to clear away. Moreover, it was constantly increasing. Once part of it was cleared, more would emerge.
