This is truly a door, built into the mountain body, tightly locked, with no indication of what lies inside.
"Could it be the entrance to a treasure vault?" the Black Donkey suddenly became excited, "Zhou, take a look. Although there aren't many corpses here, we saw quite a few on our way over, and at least at the Milky Way Realm! If you ask me, the human alliance must have fought all the way to the treasure vault of the Black Bone Freaks, and the Black Bone Freaks resisted desperately. In the end, both sides perished completely, leaving everything to us for free!"
This speculation indeed seems likely to be true, but Zhou Heng had an ominous feeling in his heart, unable to express why, but it made him uneasy, as if something terrible was lurking behind the stone door.
"There may be great danger inside!" he pondered for a moment, "Let's eat those Blood Spirit Fruits first, enhance our strength, and then explore!"
