The crowd was arguing because they collectively possessed the magic necessary to cross to the other side. Using their Dharma devices, they could withstand the terrifying rule pressure and connect the other half of this Broken Bridge.
However, everyone held their Dharma device in high esteem, reluctant to risk their own for fear of damage. They knew that such a risk could render this trip to the Ancient Road Illusion pointless.
This was a big gamble. Everyone had hoped others would bring forward their Dharma devices and they could get the edge, but because everyone was of the same thinking, it had resulted in a half an hour of shouting match.
Among them, a few even had throne level Dharma devices, something an average person could not possess even in a hundred years. Those devices were their source of strength and confidence. Surely they couldn't just let others walk over them.
