Elder Wei and elder Jin took turns to use their divine sense to monitor the entire iron prison and the area within a ten-mile radius. For people of their cultivation levels, using their divine sense in such a way was not a burden at all.
Before the loud noise was heard, elderly man Wei had already seen a Black Rainbow coming from the ninth heaven.
"There's a situation." Elder Wei said in a deep voice.
But he didn't stop her.
The red light came with great momentum and suddenly exploded on the southern side of the large iron prison. The explosion was so loud that even the ground shook. However, elder Wei's expression did not change. He only said indifferently, " "I'll go out and take a look."
With that, his body moved and in the blink of an eye, he had already turned into a breeze and arrived high in the sky.
When the smoke and dust dispersed, the outer wall of the iron prison was indeed not damaged at all.
