Practicing in a Different World and Meeting a Female Vampire

After entering a mysterious castle, Lin Chengren discovered that a mask with the power of the parasitic Nordic god Loki was buried under the castle. Wearing it will activate the subconscious desire in your heart. After touching it, Lin Chengren was reincarnated into the Middle Ages, and his only relative disappeared. He found that the aura of the Middle Ages was richer than that of the original world. By practicing here, his perception and reaction abilities could be greatly improved. He simply became a superman! Just when he was about to breathe a sigh of relief, he discovered that the world was far darker than he imagined. The church, vampires, ancient gods, all kinds of terrifying dark forces are ready to move. How can I continue to survive here? Can the results of my practice be used to kill gods?
