The Inferno of Hell danced violently in his palm, emitting a deep, devilish whistle that made the rocks in the cave shiver. After obtaining the ancient immortal's remains and sword, Wu Qi had quickly found himself this cave to digest everything that the immortal had left behind.
The broadsword, ten feet long, as wide as a palm, and as thin as paper; red and shaped like a centipede, was twitching and tossing about in the inferno. Wu Qi had poured over ninety percent of his mind into the flames, sending wisp after wisp of flames into the sword to break through the complicated restrictive spells within so that he could brand his own divine sense in it.
