The Alchemist actually felt quite uncomfortable with the problem occurring before his eyes at the moment.
He swallowed the potion slowly, enduring what felt like an unbearable bitterness and a slimy, viscous sensation.
In the end, he completed such a transformation.
The ebullient power that surged from the depths of his soul made him feel as if he was no longer himself at this time.

However, as an Alchemist, he knew all too well the potent side effects of his own concoctions.
So, facing what lay before his eyes, he hoped he could restrain himself as much as possible from the use of these potions at this time.
Therefore, not to exceed that potentially deadly threshold, yet also to possess something that people should fully accept at the same time.
