In other words, this round would rely on both individual power and teamwork. At the start, all participants will enter the forest from different areas. Even if they want to team up with each other, they still need to survive until they met other members of their team
Cairo knows that the level of his team was lacking and even if he wants to team up with them, that is still a hard thing to do. The participants from the Larton Kingdom might possibly be eliminated before they group up
Besides, even if Cairo have a good plan and encounter his teammates, it would be hard to have them obey him. Those geniuses clearly don't like him
Also, Cairo doesn't have a choice but to team up with the other geniuses. With their level, it would be hard to prevent the Larton Kingdom from having the lowest ranking
Cairo needs all his teammates to help each other to at least be placed second to the last. As long as he can do that, it would already be enough
