"I thank you for your advice, Your Highness."
Cain clasped his hand and bowed toward the Collapsing Lightning Duke for his words.
The Collapsing Lightning Duke nodded before staring into Cain's eyes for a while and finally raising his index finger, generating a drop of blood. He began to charge a massive amount of black lightning into it, and once it reached its zenith, he sent it toward Cain.
Cain's eyes widened when he saw that drop of blood flash toward him, and it was so fast that before he could do anything, it landed on his shoulder, generating a strange rune in the form of a lightning arc before vanishing beneath his skin. He could not help but frown since even if he detected no danger from the drop of blood, he did not like people doing things to his body without asking.
