Yet another victim of the inscrutable synopsis. Look, Ji is a disgraced Imperial prince who also happens to be a transmigrator whose goldfinger activated too late for him to stop the scheme that got him locked up in a library with nothing but Buddhist sutras to read. ONLY! His goldfinger's skill is to assimilate whatever he reads and immediately make him a master of whatever skill generates. Now, it's up to him to defend his only blood sibling and overturn the Heavens (and his neglectful father) to take his rightful place as ruler of all!
