I mean, endeavour was more just the father wanting it.This is just straight, classical, eugenics.

eh, it's close enough. I remember that the process did involve the spirit beast willingly joining. plus each spirit soul could give multiple rings

convince a spurit beast to willingly become your ring. also allows cultivation of that rings age

Some may even call it... a redistribution.

Well, you CAN volunteer.
