Lin Lehan resumed experiments on the living and the dead to come up with a novel method.
His latest invention was the creation of new and improved alchemy dolls.
The stable and successful process of alchemy dolls was created by merging the concepts of homunculus and Mana Body Creation. This fusion allowed users to alleviate some restrictions they faced with elemental clones and homunculus vessels.
Essentially, users could split their attention as if they were using a perpetual elemental clone without harming their souls. The range of the alchemy clones was also not an issue.
Plus, they were self-sufficient and hardly needed any resources to sustain themselves. They had synthetic mana cores within them, which allowed the users to use them as if they were using their real bodies.
