"Fighting An Unfair Battle" 

The chaotic space fluctuation means that the teleportation tunnel could not be opened safely at all. 

Even luck might not be able to save people if they insist on using an unstable space tunnel. 

When the sonic guy told the others that they could not open the teleportation tunnel at all, some quick-witted people had already thought of a guess. 

Could it be that the Academy knew they could not open the teleportation tunnel anymore for an unknown reason, which was why they didn't say anything to avoid spreading panic and unrest to the survivors? 

If the survivor discovered the issue by themselves, they might be a little calmer than if someone dropped the bomb and told them that the situation was hopeless. 

The space fluctuation was so great that it was impossible to open the teleportation tunnel in a short period of time. 

They might have to wait for several more hours or even days.
