"I—will—kill—you!"
The Vampire Duke was burning with rage, his body's power surging wildly. It was unclear whether the sea tide was influenced by him, but it incessantly battered the cargo ship, producing the constant crashing sound of the waves.
Ye Wudao immediately shed his relaxed expression, feeling the powerful strength of this Vampire Duke, and he dared not take him lightly.
Opening his mouth wide, the Vampire Duke roared and released an invisible shockwave at Ye Wudao, instantly causing a buzzing in Ye Wudao's ears and an abnormal heartbeat. It felt like countless knives were digging inside his head, bringing on an excruciating headache.
"What a formidable sound wave attack!"
Ye Wudao quickly sealed off his hearing, and the noises in his ears and head ceased. Had he been any later, it might have punctured his eardrums, or even caused his heart to burst.
