The balance of victory in the great decisive battle had already tipped toward the Alchemy plane from the moment Su Lun summoned the puppet army of a million.
Armed with secret weapons like "Twilight of the Gods" and "dark matter bombs," which could be considered dimensionally-reducing strikes, as well as warriors who disregarded life and death, the mages from the Divine plane were naturally beaten back step by step.
Following a broken formation, it was often Su Lun's million puppet legions charging ahead first, smashing through various large magical armies; after which the mechanical warriors swarmed forth.
Once it entered the melee combat phase, the Alchemy plane completely became the dominant side.
The physically frail mages, deprived of the protection of their magic formations, faced the upfront assault of mechanical warriors and were almost uniformly overwhelmed.
