Seven mages used their full potential to create the barrier. Hence, the barrier is only as powerful as seven human souls. So, it takes that much power to match that of the barrier, and hence, destroy it.

If more mages helped make the barrier, it'd likely be stronger. But, mages are exceptionally rare, most humans can't use magic at all!
