Xiao Hei soared into the sky like an arrow shot by someone powerful. It tore through the darkness of the night before focusing on flying in a circle above the black building where the Hell Prison was located.
Its wings flapped in a steady rhythm, while its claws suddenly penetrated the pouch tied to one of its legs. Instantly, golden dust shot out from the hole that the claw had just made, and it fell to the ground like a curtain of rainwater.
However, before the golden dust fell to the ground, some of it spilled over the soldiers guarding the black building. It turned out that soldiers were patrolling around the black building, and golden dust was accurately flying over them because the crow was flying in circles above the building.
