They headed to the place where the last communication device used by numbers 3 and 4 was active. Number 2 directs the route to get to that place.
Because the Forbidden Forest is in the middle of Ohio City. So their journey doesn't take long.
Along the way, no housing was found around the forbidden forest. There is only a straight road and bends in some parts, flanked by two forbidden forests that are on the right and left of the road.
There are also several countable stops when drivers are about to refuel their vehicles. However, the place is independent, so no guard is guarding the place.
Maybe during the day, there will be several cleaners guarding every stop in the forbidden forest area. But by the time the sun had set, the officers decided to leave the stop they were supposed to be guarding.
Because they love their lives more than their extra salary.
