Leon's body began changing immediately after he took the pill.
His shoulders broadened, his height grew by almost two feet, and his skin turned a charred black color. His blood vessels crystallized and broke through the frame of his body, manifesting as red magma-like lines on the surface of his skin.
"AHHHHH!" Leon roared. The pain he felt as he transformed was intense. Rampaging mana filled his body and entered the mysterious pocket within, enhancing even his base abilities by a large portion.
This type of pill could only be created by a Demigod. After all, it forcefully raised the level of one's soul as well as their body.
Leon opened his eyes a mere second later. Their previous color was gone, replaced by the bloody color that overtook the rest of his body. Just by looking at his figure, one could easily guess the type of burden he placed on himself.
