There is a guy being examined in front of several masters, the masters who prepared the room and everthing else to ensure that the guy examined can not cheat, so this guy sitting, without leaving his seat, only sees the masters practicing their 'arts' and tells the faults of these arts or answers some questions of these masters.
And you expect these masters to deduce that the guy being examined has divine power?
It is very clear from the beginning of LOHP that the place where the MC starts is a rotten land, instead of thinking that the Alchemist Masters have for some reason to guess that the protagonist has a divine power, why do not you consider that the Masters may have been thinking "this kid is probably apprentice of a Master from outside these rotten lands"?
Dan, I'm on chapter 550 and there not one metion to sometin close to the Mc power, not one, is basically sometin never seen before in that world and you espect to some Masters of a rotten land to guess it?
