The prisoner was still under suffering from a joint attack from ten Xue Yings, all while also being bound and restricted by the black shackles. He was a Great Demonic God, yet he could use neither his domain nor his World Deity energy reserves. He did not even have a weapon! He was limited to moving within an area of a dozen meters under the entrapment of the two shackles, which left him feeling truly stifled. At the same time, he was accruing heavier and heavier injuries; many of his scales were already crushed, and there were cavities all over his body. Healing them would require lifeforce he wasn't in any position to use.
"How long has it even been? A thousand years or so? You… you could actually comprehend such a destructive secret skill?" The Great Demonic God was well aware that his defeat was nigh, followed by his inevitable death, yet he still found it hard to believe.
Xue Ying did not relent at all, continuing on with his berserk assault.
