An Jing didn't respond and instead had someone bring over a stove, first placing a piece of honeycomb briquette inside and then adding some firewood to ignite the briquette.
Seeing that the briquette burned just like charcoal, Emperor Xiyun's eyes immediately brightened, "What on earth is this? How can it burn?"
An Jing said, "This is something from underground; I'm not sure exactly what it is. I discovered it could burn when it accidentally came into contact with fire. Meng Zhuqing once saw this material with General Meng in Emin. Later, Meng Zhuqing had it investigated and found there are large quantities of it in the Emin region. If we mine this material and shape it like this for sale, whether in Xiyun or to neighboring countries, we could earn a lot of money."
"Father, you asked me to think of a way to run a school. Now I have thought about it and have found the material. It all depends on whether you agree or not."
