After Jingsheng left, Li Jain first tried to explain the theory of craftsmanship to Jingxuan.
He took out a simple blank sword mold, a few pieces of low-grade spirit iron, a bowl of prepared refining liquid, and several small tools. Then he placed them in order on the table so Jingxuan could see everything clearly.
"Refining is not as simple as melting metal and shaping it into a weapon. A weapon that can be used by cultivators needs three things. These things are: a stable material body, a proper energy flow, and a structure that can hold spiritual force."
Jingxuan nodded seriously.
Li Jain looked at him: "Do you understand? Would you like to take notes?"
Jingxuan hesitated for a moment before saying, "I'm OK, let's not make this like a real school ok? It makes my head hurt."
Li Jain laughed: "Ok, forget about the book."
