This time, only letting go, after the number following his finger stopped at 70. Seeing his curiosity, Annette couldn't help but giggle a little, before saying. "Nifty, isn't it? The temperature can change to your desired setting within seconds. That's why only adults can change the settings on a key. Children are incapable of using these keys for safety reasons.
There's even an age scanner on each key that's designed to scan its user, in order to make sure no underage children are operating it. I know this because my chariot and home also have similar keys."
Hui Shi eased into a smile, after hearing Annette. He then continued where she left off, saying. "Sister Annette is right. Children are truly incapable of operating this key, due to safety reasons."
"That's a useful feature. It shows there's been a lot of thought put into the designs of these runes and keys." Lain added. He then took a moment to look around the screen in front of him before finding the sofa that he was currently standing in front of.
After finding the sofa, he reached towards it, then swiped up on the sofa. After a second of swiping, he only stopped when the setting number that hovered next to his swiping finger reached 100.
"I forgot to mention what the rating numbers indicate for the sofa. Number 100 indicates complete firmness, and number 0 indicates complete softness." Hui Shi added, in slight guilt.
"I see. Thank you." Lain replied. He then sat down on the sofa, in order to test what the words "complete firmness" truly meant.
As soon as he sat down, he felt the difference. Before, the chair felt extremely soft and comfortable to sit on. Now, on the other hand, sitting on the chair felt like sitting on a hard rock.
Lain, while feeling the texture of the sofa, reasoned to himself. 'It seems after the rating number reaches 100, the chair will go back to its normal texture. And since the sofa was carved out of some sort of stone, I can only feel uncomfortable sitting on its rock hard surface.'
"The texture of the sofa actually gets firmer than its original texture, due to the runes carved on it. I heard the runes of most furniture can make them much harder than they originally were. They can even turn water into a hard, rocky material. But I've never been in a house that doesn't use pervite as its building material. Since all houses in our district are made of it." Annette said, after seeing the look of realization on Lain's face.
"Pervite is the name of the stone that all buildings and furniture are made of in this district, if you're wondering. Even our city has many architectures made out of this stone, due to its light weight and great durability." Hui Shi added.
