<em>"Emperor:</em>
<em>I am writing to inform you of a recent development that might prove useful to the future of your dynasty. We have received information from alchemists who have discovered a type of material that is highly explosive. They discovered such potential weapon accidentally, but were eager to report their findings for two main reasons: first, this material can most likely be used as a weapon in order to defeat our enemies, and second, we might be able to use it in other industries if we learn to control it. There is a possibility of even using it in medicine. I urge you to pay attention to such development, as it might prove to be very important."</em>
They should allow every person in their society to be happy and free
