Magic Stone Gourmet: Eating Magical Power Made Me The Strongest

After receiving a divine gift from the Goddess, he was reborn as a nobleman. Though the prospect of his new status was exhilarating, he felt humiliated by his unremarkable "Toxin Decomposition EX" skill and was ridiculed by his family. However, one day he realized that his ostensibly pointless ability allowed him to devour the magic stones of monsters and absorb their strengths. Astonishingly, he found out that he was actually the prince of a neighboring kingdom. Upon arriving at the impressive palace, he found an appropriate environment to refine his abilities and experiment with an array of magical stones. This enabled him to achieve his true potential, such as obtaining the power of the fabled Dullahan monster. With a committed fiance and a bumbling knight as his allies, he embarked on a journey to ascend to the throne.
