Wang Batian saw that the Underworld Killing Formation successfully trapped Lin Feng, immediately revealing a smug expression on his face. He thought to himself that Lin Feng was not much of a challenge after all. Had he known Lin Feng was this easy to deal with, he would have acted earlier. Thinking of this, he didn't want to waste any time and simply said, "Nether Dragon Heart Slaying!"
As soon as Wang Batian uttered those four words, the nine Blue Underworld Heaven Swords surrounding Lin Feng suddenly sprang into action. From each of the nine swords shot out a black dragon, each comparable to the two black dragons that had just attacked the transparent light membrane. The sight of nine several-hundred-zhang black dragons entwining in the air was utterly terrifying!
