The Vampire Curved Knife, SS level, resembles a pirate's curved saber from the Age of Sail, with a slender arc blade, an all-black body, and vampire carvings imprinted on it. On the hilt is a pair of demon wings. It has the ability to break demonic forces and spiritual beings, dealing double damage to spirit-type monsters, and has a 5% chance to inflict a lethal one-hit kill on the wounded. It also possesses a mass killing skill called the Vampire's Kiss, which launches a multitude of self-destructing bats that bomb targets and carry a curse, doubling the amount of potion required to heal the wound.
Landeck knew that trying to kill Tang Zheng with one strike wasn't realistic, so he aimed at his arm that was stripped of Hellfire. To sever his arm first, even if he wore the S-Class Firefly, the opponent couldn't withstand it, after all, this was the limited edition weapon he had bought with a lot of points and materials.
