Decades ago, Vlad, one of the two top beings of vampires, betrayed vampires and kept sucking his own kind and humans for power. Finally, he offended Lapis, the other top being. Because Vlad was too powerful and could control all the beings he had sucked, the first cooperation between vampires and humans kicked off, and the church he belonged to was Black Trembling. Xia Xihuan and Lapis, the captains of the Dragon Wings team, sealed Vlad after several twists and turns. At the same time, the two fell in love and left the fruit of their love, a boy and a girl. Huan was expelled from the church for helping a heretic. Zhengdao Huan and Lapis were immersed in the joy of ordinary life. The darkness was about to stir, and the second vampire-human collaboration-the red ghost trail kicked off!
