They Agreed to Just Be a Blood Slave, but the Vampire Lady Panicked

The mountain climbing date turned out to be a murder trap carefully planned by his girlfriend! Just for a sky-high price insurance policy, Su Jingchen was pushed off the cliff and shattered to pieces. When he opened his eyes again, he saw rusty iron bars, cold chains, and the permeating smell of blood - he had become a "blood slave" prepared by the vampire clan for the princess' coming-of-age ceremony in a deep mountain castle! The beginning is hell, and the system subtitles ruthlessly declare: [After one minute, bleed to death] Years later, the gears of fate turned. When the scheming ex-girlfriend who had pushed him into the abyss appeared in front of him again with fear and unwillingness, he lazily hugged the beautiful vampire princess next to him with silver hair like the moon, but her eyes suddenly became dangerous and alert. He gently lifted her delicate chin with his fingertips, and a playful smile appeared on the corners of his lips, but his eyes were locked on his ex-girlfriend coldly. "Why are you panicking?" His voice was filled with god-like indifference and jesting, echoing clearly in the dead air, "I promised you that I would only be a blood slave, my... Your Highness Elise?"
