Blood Essence.

Shi Lang was knocked unconscious, and the Dragon Snake still moved toward him. However, just when it was about to kill Shi Lang, Long Shan appeared in the voice and exclaimed, "Insolent Beast!" 

The pressure from his voice made the beast retreat a bit, but the Dragon Snake did not stop roaring in rage. It coiled up on the ground, and then it flew off the ground. Long Shan was surprised by the peculiarity of this beast, but he had no idea about the strength of this beast. 

The snake was in midair and snapped its tail to hit the old man. Long Shan narrowed his gaze and took out a sword. He slashed it at the beast. A strong sword intent rushed out from the blade and clashed with the snake.
