Downtime Puzzle, again

[GM-Ayu]

Question 2: 5 Rainbow Cake, 5 GB OCA

Suppose that you meet up with 8 new novices to explore the world of heRO. Because they were nubs and is not used to a low rate, they didn't go through training ground to get some free stuff. They all want to be assassins one day (because we all know that sins are pwnage?) but they are not used to how to walk to town of Morroc on foot, as they are corrupted by high rate free teleports. Although you can give them zeny to teleport by kafra, it doesn't help them in the long run though if they don't know their way around. So you decide to lead them by foot to travel to Morroc.

With 8 new novices, you arrive at a 4 way intersection. Then you realized that you really haven't walked on foot through Sograt to get to Morroc either, and you forgot that we actually have a world map ingame. You don't want to lose face in front of the novices to say that you need to alt-tab to find a world map though.

You know that one of the 4 proposed paths will lead to morroc for sure. It should only be a 1 minute walk to get there, counting the time to avoid monsters and all. So in theory, it's possible to all travel one path in one minute, and if you realize it's wrong, it'll take another one minute to get back to this intersection point (and of course, you may also participate in this walk to find Morroc as well). Then, you can go on another path to try again until you find Morroc. However, to do this task efficiently, it's best to divide the group into smaller groups, take 1 minute to travel down one path, rendezvous at the intersection in 2 minutes, then the group will know which path to take by the 3rd minute.

Problem is, 2 of these novices are mischievous and sometimes lie. You don't know who they are, and they may not always lie either (they got the ABILITY to lie.)

Find a method to guarantee that you will always find out which path leads to Morroc and arrive in Morroc within 3 minutes. State your method and reasoning for why the method works. Assume that you are not a fat retard who lie to yourself about what you find (aka, you yourself, will always tell the truth.)
