Radioactivity of uranyl acetate
At some time, a different person in a workshop made a thing called uranyl acetate. This thing is radioactive, its light is faint, and it feels strange when touched. Its energy can be changed by primers, and it is comparable to unusual things.

The craftsman did not know the danger at first, and often touched it with his hands. Not long after, he felt unwell, his body was getting weaker, and he was plagued with various diseases. A wise man saw it and knew the harm, so he told everyone not to approach it.

Everyone is afraid and wants to discard it. However, it is not easy to dispose of this thing. If you discard it in the wild, you will be afraid of sewage and soil, which will be a disaster for all parties. The wise man finds it, gathers the strength of everyone, builds a room, thickens its walls, and hides uranyl acetate in it, so that a special person can guard it to prevent accidents.

From then on, everyone knows that although the strange things in the world have wonders, their hidden dangers cannot be ignored. Be careful not to cause disasters lightly.
