The Only Aura User In Magic World

One week later, we still did a lot of training in this testing ground. I don't think I have achieved a satisfactory strength to fight master level mages.

There are many of the ancient Aura users here who have fought against master level mages. Some win and some lose. And they still think that I'm not strong enough to defeat a master level mage.

I haven't finished Mona's training to improve my Divine Vision. But I can train it while doing other training with other ancient Aura users. It's better this way.

"...so, you want me to teach you while you're blindfolded?"

The one who asked me was the ancient Aura user I asked to be my partner. He's someone who is specialized in assassination.
