Capítulo 1897: Hall of Enlightenment  

"Here is the air pen you had asked for," Commander said as she gave me the wonderful artifact. This crystalline red pen had many names, runic pain, carvers pen, and others.

The basic function of it is drawing runes; it can draw runes on air or on the ground. The most amazing thing about it, that this pen could be bounded, and once it, I would be able to make it draw the runes from my mind, it would be able to draw the huge formation, which took hours could be drawn in a minute.

The level of this air pen is very high; it would work much better than the air pens I had read about it before. I wanted to look at all its features, but there are other things for me to do. So, I carefully stored the air pen in my storage and looked at my next target, the bookshelves.
