I Am Ordinary and Rely on Magic to Prove the Truth.

Chen Du was transformed into an inconspicuous side branch of a family that cultivates immortals in a fantasy world. His original talent was mediocre, his cultivation progress was slow, and he was like a transparent person in his family. A piece of Bing Xin Jade that he got by chance made him accidentally discover that his ability to deduce magic had improved by leaps and bounds when he was vomiting at night. At first, he just "senses" trivial things, until one time, he accidentally uncovered a catastrophe that happened to his family not long ago... On the way to the Star Academy to take the exam, he held the Star Token in his hand, but he had no idea what kind of waves his quietly awakened talent would cause.
