The most efficient way to defeat them is to go in order from 1 to 7, this is without spending any time breaking any barriers. Defeat the 1st wise man, jump over the wall to the 2nd wise man, then take a turn head for the 3rd wise man. It is crucial to backtrack your steps after defeating the 4th wise man, going past the north-west neutral base and head left instead of going straight up, because there will be an obstacle in your way. After defeating the 6th wise man simply rush back to the starting point and defeat the 7th wise man.
