The Devil Has a Special Quirk

As the "princess" whom the Demon King made harsh words to abduct, Zhu Yu was so angry that he put on his vest and became a knight to kill the Demon King. He vowed to keep the shocking secret that the princess was a man, and embarked on a dangerous road for his own life. He found the devil. He sneaks into the opponent's territory. ... The assassination failed, and he was dragged directly to the bed by the Demon King. Rumor has it that the demon king who kills without batting an eye is indeed a murderer without blinking an eye, and he also has eccentricities. "Are you the brave man in the prophecy?" The Demon King, with fresh blood on his face, rubbed Zhu Yu's chin and asked slowly. Demon King: "Come to kill me?" Demon King: "You look good and suit my taste very well. If you serve me well, I will spare your life." Zhu Yu was so frightened that his face turned pale. *** [The prophecy says that the devil will be surrendered by a human hero] People all over the continent are looking forward to that brave man killing the cruel and violent demon king and ending these days of fear and oppression. Unexpectedly, not long after the prophecy came out, the magic stone that recorded the appearance of the brave was openly snatched away by the devil. Everyone looked horrified, fearing that the murderous demon king would find the human hero and get rid of him in advance. *** Silent night The Demon King stared obsessively at the human image projected in the magic stone, like a hungry ghost playing with his body unsatisfied, and his voice was ambiguous: "The brave... Ha... Whoever the brave is, he is mine from now on." What they don't know is—— The Demon King held the magic stone that recorded the appearance of the human hero and watched it day and night. The Demon King, who had been abstinent for hundreds of years, wanted to snatch this man away from him at the first sight. He was so stunned. Until he saw the "princess", but it was a pity that the gender was wrong. But it doesn't matter, the Demon King thought grimly. First capture the princess, and then force the old king to have another one. The appearance is so similar, if it's not her brothers, it must be her younger brother. The brave man he thought about day and night would soon be born. Mission: Even if you are in trouble, you can break through the clouds.
