The world of Alchemy wasn't strong. Amongst the lower realm worlds, it could be said to be the weakest. However, it was also the most peaceful world with rarely any large scale conflicts.
The alchemists in this realm focused on cultivating their internal energy and exploring the mysteries of Alchemy. Their harmonious coexistence allowed them to exchange knowledge freely and make remarkable advancements in the field of medicine.
However, their peace had slowly started disappearing. As soon as the Frost Mountain was destroyed, and the Frost Dragon killed, this world had lost their guardian.
It was the deterrent of the Guardian which had kept the other Lower Realms from getting greedy and targeting this world. But now, that deterrent was gone.
Every day, many people from other lower realms arrived in the Realm of Alchemy, treating this world as their home where they could do anything they wanted. They had no fear anymore.
