Hi
most guide I read ,include here.tell me to solve th puzzle,the best way is upgrade all tech and bring my villager to every parts.different villager see different things

my question, if I have a villager that mastered in 5 skills, do only bring him everywhere is enough? Do he can see everything other can see since he mastered in 5 skill?

And how do I know wheter my villager mastered in 5 skill or not?because after mastered 3 skill,they become elders. I cant see the rest 2skill mastered already or not, since adept who almost be master is simmilar with master according to blue bar..

For the question. You will tell that in detail.
