In the depths of the oddly shaped palace, outside a grand hall, the Swallowing Sky Toad and Hellhound quietly guarded the door.
Especially the Swallowing Sky Toad, with its body dozens of feet large crouching on the ground, if it weren't for the slight rise and fall of its snow-white belly, it would truly resemble a statue.
As for the three Hellhound, it was even more ferocious and terrifying.
This creature with three terrifying heads, its slightly open mouth revealing sword-like sharp fangs, emitting a chilling gleam, and its three pairs of vicious dog eyes made any life passing before the hall shiver.
Fortunately, this place is deep within the palace, apart from a few strong individuals passing by, usually, no one comes here, so one wouldn't have to face the Hellhound's unfriendly gaze every day.
This is their master's place of isolation, and the two of them volunteered to guard the door, preventing outsiders from interrupting their master's cultivation.
