These patterns...
They are designed to enhance the hardness of these materials and the control of the spirit puppet's core over them.
Spirit puppet...
Its body is full of intricate patterns. Though these patterns appear mysterious, they serve the simple purpose of making the puppet easier to manipulate and more durable.
The most important part of the spirit puppet is its core.
Crafting the core is when He Song's skill truly comes to the test.
The patterns currently being engraved into these materials are just sculpting the body of the spirit puppet, making it more resilient and less susceptible to destruction.
And since the body is cast in one piece, the durability of the spirit puppet will significantly increase.
After crafting the body of the spirit puppet and ensuring its durability,
The next step is to shape the form.
He Song stretches a large lump of materials in front of him and tailors it into a human form.
As for the likenesses...
