I, the Vampire Viscount of Victoria

Medical student Linn traveled to London in 1886 and became a viscount of the Nosferatu family. The family was destitute and debt-ridden, and all that was left in the manor was an old butler and two crumbling chairs. He wanted to make a fortune through modern medicine, but he was stabbed in an alley on his first day at work. When the smell of blood came up, he had only one thought in his mind: "It's over, my time-travel life, I am a medical student who saves lives and heals the wounded, how could I be so careless?" The old housekeeper held a lamp beside him and spoke softly: "Sir, you haven't remembered yet, you are a Nosferatu." What did you remember? Come to think of it, your whole family is a vampire.
