Yang Yi looked again at the prepared limbs, organs, blood, and bones, feeling that when the time came, he might have to return more than just an eyeball.
The limbs had been made using the Deathbirth Society's Flesh Compression Casting Technique, with flesh from those Legendary Creatures as the main material, supplemented by the Screaming Demon's corpse and Su Na's own tissue. Bones had also been implanted inside.
Only when Su Na began the actual work did she realize the many difficulties this technique presented.
The human body was extremely intricate, from the skin and mucous membranes on the surface to the muscles and blood vessels beneath, and then the bones and organs deeper inside.
Broken down further, even the skin could be divided into many layers, including the epidermis, dermis, and subcutaneous tissue.
A complex neural network also ran throughout the human body, covering almost every area.
The Deathbirth Society exploited Proliferative Disease's ability to complete itself, so they only needed to ensure that the external contours were normal and the tissue did not overflow. Compression casting could then clone limbs and organs, or even an entire human body.
But Su Na was different. She had not used Proliferative Disease.
She had constructed many of the fine structures in this set of limbs based on her own experience, using her superb surgical skills.
To do this, she had made many sets of molds and completed the work in multiple stages. Finally, she assembled all the structures and performed one last compression casting, producing this set of limbs.
There were bound to be many shortcomings and defects inside, but all the important structures should be present. The rest would be left to the Limb Restoration Spell.
As for structures that were too complex and delicate, such as the internal organs
