In order to know where Jessica finds these expensive (not) elixirs, the person has to follow Jessica. At the first day, she observes Jessica doing her basic chores. There is nothing out of the ordinary. "Of course, Mortals are lazy people with no ambition." she commented. It is the 1st day of a week, so Jessica go finds some work.
The person followed her to the Windy Sky City. But lost track of her because of the huge crowd. "Damn it. Mortals are like Ants. They are so hard to find in a cluster." she complained. Having no hope finding her in the big city, she simply retraced her steps back to Jessica's house. Jessica was doing simple peddling with her wooden carved animal toys in the market street. Kids loved her toys.
At noon, Jessica returns home to water her vegetables. The person observes her at the roof. Nothing out of the ordinary either. "Mortals always like eating weeds. No wonder they're weak." she said with a tired face. After watering and fertilizing the vegetable farm, Jessica goes on chopping firewood. The person chuckles at the sight of a woman without partner at the age of 21, doing men's job. Soon, she will be in shock.
Jessica is cutting logs. That itself is impressive for a woman with little muscles. What shocked the person is the axe Jessica was using to chop logs. It is a War Axe normally used for combat. Not to mention that a Heavenly Grade Treasure was just used to chop mediocre logs. "I looked over the house and I never seen that lying around. Might as well take it from her undeserving hands." she said.
At afternoon, Jessica begins cooking. The smell attracts the person hiding on the roof. They couldn't resist the temptation and went down to the ground floor in order to peek in the window. There goes Jessica again, using elixirs in a Mortal Cooking. This time, an abomination that the person couldn't handle. The Chowder.
The food is a True Heavenly Treasure everyone will be looking for. And it is simply eaten away by a glutton who ate five plates of them without showing fat. Nighttime quickly comes by, so Jessica takes a peaceful sleep. The person calls Jessica, a Mortal. She is scratching her head, wondering if she brought more exquisite weapons like the War Axe that she used for chopping logs.
