Once Upon a Time, There Was a Tomb on a Mountain That Was a Space Base.

There is a large tomb on a seemingly unremarkable mountain, but the owner of the tomb is not the real owner of this place. This place is occupied by another space. The little people living in the mountains accidentally discovered this place. In fact, this place has been discovered by the military. The monsters in the mountains, the secrets of the soldiers, and the adventures of the little people will reveal the true face of this tomb in the mountain. Is it a mountain tomb, a monster's lair, or a passage to another dimension? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
