As for the remaining Magical Beasts and Earth Pulse Source Crystal, finding them would be a bit difficult... but isn't there the Ironwing Dragon?
With such a large Iron Wing Dragon Flock here, Ian felt he could take the risk to go all out and ambush a Third Energy Level Ironwing Dragon, and with that, three-quarters of the materials would be secured.
As for the last Magic Potion ingredient... it can only depend on whether they could purchase it after the development of the territory, with the help of the relationship with Yisen Gard.
Earth Pulse Source Crystal itself is a powerful Natural Spirit Energy Agglomerate, capable of creating some perpetual spirit energy constructs and also connecting to Natural Spirit Energy for self-charging. Many large-scale Alchemy projects utilize this treasure to create nearly perpetual energy sources; it is also the core material of the Lord of Stone inheritance.
