Afraid of the light, addicted to blood, and immortal… When Ke Lin transmigrated to this world, he realized that he seemed to fit all the characteristics of vampires. But the problem is, he couldn’t find any records about vampires in this world! Could it be that he is the first-ever vampire in this world? He had no predecessors to guide him. And there was no system to help him. In order to understand the powers and limitations of vampires in this world, Ke Lin had no choice but conduct experiments on himself and observe the reactions of his body: [Under direct sunlight, power levels decreased by 30%] [Throat, heart, and brain are no longer fatal weaknesses] [Ordinary foods will no longer satiate hunger, only blood can restore stamina] [Holy water… wait what? Who fed me holy water!!!
This is very much a coming of age story. Fantastical elements take a backseat to the story of Trent, a freshman in highschool at 15, who is desperate to learn more about the father who died before he was born and learn his place in this world. Scifi elements do exist and occur, but they're often cutaway events that quickly return to the school life drama unfolding among Trent and his friends. As the story continues, those fantastical elements do slowly encroach more and more onto Trent's life, but the operative word here is 'slowly'. By chapter 20 there may be a significant shift away from this, but the first dozen chapters are densely packed with Trent's life both at school and at home. Characterization comes first here, and before any of the action, the author makes sure you'll care about the characters involved in that action. If you're looking for an urban fantasy/scifi with a deliberate pace and a focus on characterization first, it's worth keeping an eye on this story and seeing if you find yourself drawn into Trent's story.
