If only separate bones are needed, then it would be much easier.
Zong Shen estimated it was the former, as normal Undead are all converted from relatively complete skeletons over hundreds of years.
The Shadow Pool merely accelerates this conversion process.
Specifics will need to be experimented with when the time comes.
In the territory, dealing with those prey has always involved skinning, chopping meat, and separating organs.
Bones and muscles are chopped into pieces; besides the large sections of fine meat and fat from the waist, abdomen, shoulders, back, and limbs, all other parts are treated this way.
Finding some complete corpses might not be easy.
So Zong Shen considered keeping the corpses of that batch of Icefield Beasts, ensuring the integrity of flesh and bones beforehand.
Having made up his mind, Zong Shen put away this blueprint.
This is a complete building made one by one; if luck is good in the future, there might be another chance to acquire it.
