During this time orion purchased a new cheap but useful system that is alchemy from fullmetal alchemist world and with its help he returned grindelwald to middle aged appreance while also inhanching strength and reaction ablity of saints
He also found out that using magical animals with muggles can produce wizards with animal bloodline but only problem is that first generation talent is not very good
So he started kidnapping children brainwashing them and transforming them into wizards then sending them to orphanage in England as they will be his supporters in hogwarts
He also planned on purchasing magic of middle earth as it is cheap but it requires resource pack to develop
There are also resource pack that are required to use some magic systems like in middle earth there is mithril and various resources that are not available in the current world
He is purchasing this magic because he have purchased one ring which is an artifact
Next power system is a bit expensive as it is spiritual reyatsu from bleach world but it complements magic of middle earth and magic of harry potter world
Magic of middle earth require strong soul and belief along with emotions to cast and magic of harry potter world also require emotions to cast
