Nice novelThe concept the author created are very good and are well implemented in the world background.There are some errors in the plot and the characters lack ‘ true emotion’, Another thing regard the MC, he’s not an idiot, but not that smart either.Try to give him a faster mental growth, the mask should heavily influence his other self.Moreover, the stronger the smart. He doesn’t need to be a genius, but if he can multitask and fight so well then he should not need the system reminder or fall in his own forgetfulness.All in all, it’s a very nice Novell that, if correctly improved, can be brought to a higher level.In my opinion the author have hope of writing top novel in the future, so keep it up.
