The Only Aura User In Magic World

There are way too many of them. Maybe I shouldn't have stopped a thousand of them here. Just letting them left through the portal.

Though if that happened,  the others will be in much more trouble. And Varadis might have been destroyed already. So I guess it''s good that I stopped many of them here..

Well, still not that good though. I have used magic to open up portals many times. And not just any normal portals. But a lot of huge portals to let several huge floating islands to enter.

I don't know how many times I can open a portal anymore today, but I know that it won't be many. Maybe five? Or maybe even less.

So, it means that I can no longer bring reinforcement here. The good news is that the vampires can fight and recover their stamina at the same time.

Though now that I have a knife hand, my fight is getting easier. Unfortunately, it's just a knife. If I still have my right hand, then I can fight even better instead of just relying on a knife.
