So let me get this straight, he wants the Duke to send him to some battlefield so that he can earn a title , which will mean he will reveal his cards and show everyone how strong he is eventually, under 3 years , so why not just present either the ring ( ana said if he present it to the ring , king will even be willing to give him a title ) or the national treasure the sword and ask for a title in return , if they question how he got it , he can just showcase his power ( which he will do under 3 years anyways ) .... So , make it make sense ..
