The Only Aura User In Magic World

The Vampire King has become much stronger than me, but with my portals, I still have a chance to win. Though the Vampire King can still get stronger.

First, he can just drink my blood. That means I must never let him wound me again, or he will just get stronger.

And then, it's because there are still vampire's corpses in the area. They are the ten vampires who wanted to kill me even though I allowed them to leave.

Although I think the power he gained will be lesser than when he drank the blood of the Vampire Dukes, he can still get stronger.

Though if what he said about losing his mind is right, I might have a chance to win if I let him drink more blood. He will lose his mind, and his moves will be predictable.

But I don't want to trust in a small chance like that.

Usually, those who I fought and get provoked, will have their moves easily read. But they were all at most as strong as me. But this one is already stronger than me.
