All of them were completely surprised when they heard this.
They couldn't decide what to do. Of course all of them wanted to survive but they failed to understand what Rex would do.
They were just staring at each other while waiting for someone to make a move.
They really wanted to go towards his right side but some of them thought that it was Rex's thinking that he would kill only those who would come towards his right.
That's why 10 of them stayed back while the remaining 10 moved ahead towards Rex's right side.
They believed that Rex wouldn't kill them since he had already told that he would allow only some to live and maybe this was the opportunity.
Rex saw that they had divided themselves equally. Ten were towards his left and the other ten towards his right.
"Haha, that's good... this time there wasn't much confusion...", Rex grinning in an evil way.
