Humanity is at war with the vicious Luo people, and they need help more than ever. Now, humans who have been hiding in the shadows for centuries, those with extraordinary abilities, are beginning to step forward. Some choose to share their knowledge with the rest of the world to help win the war; others choose to keep their abilities secret.
Li Yang loses everything in the war: his home and his family. All he inherits is a battered old book that he cannot even open. However, when the book finally opens, Li Yang gains a System that completely changes his life. By completing one mission after another, he grows stronger and stronger. Then one day, the System gives him a task he isn't sure he can complete: "It's feeding time! You must drink human blood within 24 hours, or your HP will keep falling until the task is complete."
