I skipped some chapters and it seems he still didn't tell Merlin his identity. And also he uses spells over level 7 when he is so young and expects to be ignored? And how is he supposed to lie again after he uses the lvl 10? No wonder this guy is the weakest Emperor, he is also the dumbest one. And from how dumb he is to become an emperor I think his talent in magic is the strongest in the world
