Qi Yue indeed could not die. The moment he charged into the area covered by the ball-shaped lightning, he knew it. To conserve energy, Qi Yue directly activated the Immortal Domain. No matter how fiercely the ball-shaped lightning attacked, it could do nothing against the Immortal Domain. Watching the thunder attribute energy burst over him relentlessly without causing any harm, Qi Yue's understanding of the KongTong Seal deepened yet again. It truly deserves to be one of the top ten Divine Artifacts! With it, his strength had invisibly increased a great deal, and his chances of survival became even greater. If only the Xuan Yuan Sword were still with him, then in the evenly matched situation just now, perhaps he and the Bull Demon-King could have taken down Satan together. A supreme Divine Artifact could often be the key to determining the entire outcome of a battle.
