Li Wei took a deep breath, looking at the mysterious characters that he arranged in the air with the help of the spirits.
The characters were like a magic script from games, however, with more different variations that have a meaning of itself.
These characters can only be formed by spirits; even the gods were no exception.
As for why the spirits can form these characters, it wasn't written in books, and also no heroes and sages know of it.
They only knew how to create skills after a gifted person with the ability to talk with spirits found out about it.
However, they didn't know how to arrange the characters with logic because they learned everything through the skills and never understood anything at the technical and basic level.
So when they finally understood the characters, a few decades were already passed away, but it didn't end here as the most important part was skill creation.
