Matthew tried hitting the invisible barrier a couple of times and he even uses his aura hand-blade to try to cut through the invisible barrier, but none of his attacks worked and the invisible barrier only tore for a millisecond before quickly recovering after being cut by his aura hand-blade.
'Should I use the solid aura hand blade…?' Matthew considered in his mind.
But after checking his aura core that started to look transparent of light which indicates that he didn't have much aura left, Matthew turned off his wolf aura ability and thought,
'If I use even more aura here, will I have any aura left to use to fight the army attacking the village…? And using the solid aura needs a very significant amount of aura, if I used it here to try and break the invisible wall then I don't think I could spare any to use later.'
