Actually those people also did not want to contact Alex while he was in the danger zone because this could also make them on the bad side of Alex. Currently many people are already waiting for him inside of the kingdom but unfortunately they did not find any clue about him inside the kingdom so naturally everyone thought that he was still present in the danger zone.
Also those people naturally did not want to send that many people to go inside the Danger zone to search for him. Because of these they just only send two people inside the danger zone to look for that person and if they are really able to be found in the shoot they immediately reach and come back to the kingdom to report them.
