Soul Dividing Technique…
It was a secret technique of the experts in the antiquity time. This technique would divide the host soul into parts. When they forged the puppet, they would put a part of their host soul into it. This would make the puppet have the soul and memory imprints of the owner, which would help it to perform as marvelously as its master.
The secret weapons of a great blacksmith or a warrior required a part of the soul pouring in to be opened.
As long as he had his soul enter the tools and the books, he could officially control the tools and read the books. It wasn't hard to learn how to divide the host soul. However, most of the techniques were lost. Only some members of the old factions knew how to do that.
