I Use Science in a World Full of Magic

Lu You, a seventeen-year-old high school student, was hit by an out-of-control cement truck and died. His soul traveled to the Eldwin Empire and possessed Gareth Eldwin, the ninth prince who was abducted by the demon clan and tortured to the point of death. Waking up in a dangerous cave in the Black Wind Mountains, Lu You inherited the prince's body and memories, and found that he had a strange book embedded in the back of his hand, turning into a mysterious book of magic. This book has two core abilities: recording known knowledge and converting it into "skills" that can be used in this world. There is no extraordinary skill that can destroy the world. His biggest golden finger is all the modern scientific common sense in his mind. See how he uses scientific knowledge to fight magic!
