Su Xiao stood before the iron-barred cell door, looking at the skeleton glowing with white fluorescence inside. It was remarkably intact, with a metal cup shaped like a goblet held in its hand. A ring of white gemstones had been set around the cup.
"What's this?"
Father also stopped before the iron bars and looked at the skeleton inside the cell.
"Not sure."
Using the Aria ability from Blue Steel Shadow, Su Xiao formed a pale-blue crystal spike in his hand and threw it into the cell.
Sss—
The crystal spike was rapidly "corroded" and eventually dissipated in midair. Seeing this, Su Xiao narrowed his eyes, pulled open the cell door, then took a metal rod from his storage space and tossed it inside.
The metal rod was rapidly "eroded" before it had even finished flying through the air. Seeing this, Su Xiao turned and left at once, with Baha following close behind, leaving Father alone.
Father deliberated for a moment but ultimately did not enter the cell to investigate. The Prison of Pain was fraught with danger, and some seemingly insignificant things were enough to prove fatal. He had already been injured by the Sun Warrior and had used up a large amount of restorative supplies. He could not afford to take another risk now.
Father left as well, while the skeleton emitting a pale-white glow remained motionless.
In reality, there was no danger whatsoever inside the cell. Su Xiao had deactivated the crystal spike himself, while the metal rod he had thrown in afterward was a composite, high-intensity oxidizing metal.
When this metal came into contact with oxygen, it underwent an extremely strong oxidation reaction. It was an Alchemy product Su Xiao had created to detect whether the air contained oxygen and whether it contained toxic substances.
