Ellie is an overlooked elf on the fringes of her people, mocked throughout the academy for being a “magic null.” During a punishment assignment, she accidentally awakens an ancient Wisdom Tree that has been sleeping for ages, and is forced to embark on a bizarre cultivation routine: tell a joke every day in exchange for knowledge. Meanwhile, Russell, a human duke, arrives in elven territory under the pretense of conducting an inspection, but is actually looking for a way to break a curse. He chooses Ellie, who seems like the most insignificant elf, as his guide. But as they spend time together, he discovers that this “good-for-nothing” elf is a theoretical genius, and may even be the legendary “Star Vein Descendant” capable of saving the elven race…
From then on, theoretical ace Ellie and combat powerhouse Russell form the perfect complementary team. As they deal with academy conspiracies, shadowy threats, and royal power struggles, they gradually fall for each other while trading barbs and lending a hand. When the greatest crisis in elven history arrives, this seemingly unlikely pair will join forces to uncover a century-old secret and rewrite the fates of two races.
