After casting the laxative spell on the unfortunate researcher's food, Alicia walked in a natural manner and proceeded to go to the third floor.
This was not because she wanted to eat, but to go to a spot where she could observe the researcher to ensure that he would really ingest the coffee laced with a laxative spell.
Sure enough, the unsuspecting researcher calmly finished his entire meal. He immediately tidied up his food tray with a satisfied smile, clearly he had been energized by his 'hearty' breakfast and coffee.
Alicia couldn't help but display a victorious smirk on her face. Carefully tailing the researcher who was already heading excitedly towards the grand amphitheater, Alicia diminished her presence to the minimum that even a passerby would only notice a researcher heading towards the area, their brains would automatically discard Alicia, who was discreetly following from behind.
