After beating all the disciples for the third time, Remira, like before, used the potion on them. But this time, everyone who was still awake discovered the real reason they recovered so fast.
That potion wasn't absurdly expensive or rare. But... the moment the liquid rushed into their bodies, they felt that "poison" they had swallowed start to move and fuse. Then, their muscles restored and grew tougher.
"I hope you remember every bit of the beating I gave you. You all attacked using your elemental techniques, and I destroyed them easily, exposing your openings and flaws. As for your bodies... using poison to improve the physique is something old and savage, but for physiques as average as yours, it works to a point; three times is the limit."
Darian's voice sounded calm, and everyone heard it without being able to move.
Remira, Hirel, and the others who were helping were speechless. They had never seen a mix of poison and potion that worked like that.
