Apart from the Giant Scorpion that Robinson William personally killed, the other four Giant Scorpions were engaged in battle with members of the special forces team.
It wasn't that the other special forces members lacked strength; after all, even though Robinson William was one of the few with the strongest combat abilities in the team, the others who made it into the special forces were no pushovers either.
They might not be able to beat Robinson William one on one, but if two took him on, Robinson William would have to be careful. If he were to face more than three at the same time, his chances of winning wouldn't exceed ten percent—of course, this referred to close combat.
Now, every Giant Scorpion was being attacked by several members of the special forces team, but they were containing them without causing much harm, mainly waiting for Robinson William to personally test the combat capabilities of the Giant Scorpions before figuring out how to deal with them.
