Sam, after leaving the battle arena, already uses the concealment technique to search for some Warriors. Until now he did not tell anyone what happened inside that basement but by looking at his expression anybody could tell something serious happened.
Fortunately, Sam doesn't have to leave the central city to finish his work. He is searching for Sam Warriors and if he does not save those Warriors then they would become a huge problem for every human of Eden Blue.
Using his observation technique in full power it did not take him that much time to search for those Warriors. Using his observation technique he can fully cover the whole city and every human being present in the city would be under his observation.
He already finds those Warriors so wasting no time he uses the teleportation technique to reach those Warriors. Sam searched for 5 Warriors but unfortunately, those 5 Warriors were not present at the same place.
