Lu Changsheng inspected the puppet he had installed, appraising it.
Puppets weren't as strictly confined as talisman making.
After understanding the principles, one could flexibly modify certain minor areas depending on the situation.
Then, Lu Changsheng removed the golden Heart Protecting Mirror from the chest of the puppet.
Inside was hollow, being the core of the puppet's spiritual control mechanism.
If the core were damaged, the puppet would be wasted, necessitating major repairs.
Lu Changsheng took out a Spiritual Pattern Carving Knife and, infusing it with Spiritual Power, slowly traced over the puppet's chest core.
He needed to activate all the Spiritual Patterns and formations on the puppet's body, linking them together.
This was the final step and also the most critical one.
If he failed, he would have to check the other parts' Spiritual Pattern Formations again, re-engrave, and reassemble.
During this process, Lu Changsheng was extremely focused.
