The art of mechanical puppetry shared some similarities with the art of corpse puppetry, but the two were not the same.
Corpse puppetry primarily involved refining corpses into puppets.
They could be the corpses of cultivators or those of demonic beasts.
Generally speaking, killing cultivators or demonic beasts whose cultivation surpassed one's own, preserving their bodies and Primordial Spirits intact, and then refining them into Corpse Puppets was extremely difficult.
After all, defeating the strong as the weak, slaying a higher-level cultivator as a lower-level one, was already an act of defiance against heaven. The disparity in strength was enormous.
Ordinary cultivators could scarcely accomplish it.
Even some cultivation prodigies took pride in escaping from an expert a full major realm above them.
As for killing someone across realms, only monstrous cultivation geniuses or cultivators with special means could manage it.
Moreover, in a battle to the death, an opponent driven to desperation could choose to self-detonate.
Not everyone could do what Lin Fei did.
He could not only suppress and seal his enemies, but also forcibly erase their consciousness, preventing damage to their bodies and Primordial Spirits.
And if the Corpse Puppet one refined had cultivation far below one's own, there was little point.
Mechanical puppetry was different. It required no corpses, only precious materials assembled and fashioned into human or beast forms.
These were then refined into puppets through methods similar to artifact refinement.
The Wooden Puppet Lin Fei had previously refined from the Ten Thousand Souls Ancient Willow, as well as the Immortal Gold Puppet made from seven-colored immortal gold, were both types of puppets.
However, his cultivation had been low at the time, and his refinement methods mediocre. He had only produced puppets at the Nascent Soul Realm's successor, the Spirit Transformation Realm.
