Kneading her hand, Annalisa took a break from making a potion. In her room with lock doors and a little bit closed windows, the air emitting in her room is a little bit fatal to the people.
Limited duration she has to make the poison made her head sweat a little bit. Even so, she didn't stop until the product is completed.
After making the toxins, Annalisa put them on a sealed container and cleans up her room. Making sure not single dust could be seen in her room and all the equipment she used were now gone.
Eliminating all the evidence is part of her protocol. One time used only. No matter how expensive it is.
However, the trash she has could not leave her room without getting seen by others. The black bag that contains all of her equipment stays in her room for the time being and she waited for the night to come.
For now, she must keep her hand made product hidden not until she threw her trash. And that could only happen when at night.
