Still, silence closed the door to the study.

As soon as he closed the door of the study, he walked towards Xiao Changyi, who was sitting there, pouring tea with a teapot.

Poured two cups of tea.

As soon as he saw Quiet sitting opposite him, Xiao Changyi pushed one of the cups of tea in front of Quiet, making it clear that it was for Quiet.

Quiet smiled at Xiao Changyi as he put the charcoal in his hand on the cases between them.

"Xianggong, I've thought of a way to make a lot of money."

"What's the method?" Xiao Changyi asked while drinking tea slowly, his posture was particularly leisurely.

Jing Jing also picked up the teacup, first took two sips, and then bent his chin, and motioned Xiao Changyi to look at the charcoal on the case: "That's it, it reminds me of the coal in my original world, which can be burned like charcoal, and is called black gold, if we can find a coal field, dig coal to make honeycomb coal and sell it, we will definitely make money." ”

"Coal?"

"Uh," she thought quietly before explaining in her own words, "it's a black hard object buried in the ground, and the ancients in my original world called it graphite or charcoal. I'm not familiar enough with your world, and I don't know if any of you here have discovered this, but so far, I haven't heard of this here. ”

"Graphite? Carboniferous? Xiao Changyi groaned, looked at the charcoal on the table, and said for a while: "I haven't heard of it either." ”

Silence also groaned: "Maybe someone has already found out here, but it's not called by that name." ”

Xiao Changyi nodded, indicating that it was indeed very possible.

Tranquility continued: "Whether or not anyone finds out about it, whether it is called or not, we can be sure that even if someone uses it, it is only a very small number of people use it, otherwise, you must have heard of something like this." ”

"Hmm."

"Since we don't know where to find it, then we have to send someone to find this thing, if we can really find the coal field, the matter of running the school will be settled."

"Hmm."

"This thing also has an open air, that is, people can see it, instead of digging up the earth to find out that there is something inside, if there is such an open air here, then there is a great possibility of finding coal."

"Hmm."

"I won't tell the emperor about this first, and I will talk about it when I find something, so as not to make the emperor suspicious of me."

Even if he didn't say it, Xiao Changyi also planned to do so, and as soon as he heard Quiet say this, Xiao Changyi nodded: "Hmm." ”

Then, Quiet asked Qin San to call Meng Zhuqing.

Jing Jing and Xiao Changyi generally directly ordered Meng Zhuqing when they had something, and then Meng Zhuqing sent someone else to do it.

Of course, Jing Jing didn't directly say the name of the coal, but simply described the form of coal and coalfields, and asked Meng Zhuqing to send someone to find it to see if there was any.

But who knows, as soon as Jing Jing finished speaking, Meng Zhuqing said: "When my subordinates and my father passed by the Emin area, I seemed to have seen this thing that Mrs. said. ”

"Really?!" Quiet, surprised and delighted.

Meng Zhuqing said truthfully: "My subordinates don't know if it's really the thing you said Madame, it's just very similar, and my father jokingly called it a black stone mountain." ”

"Mountain?" It's quiet and puzzled, why is it called a mountain?

Meng Zhuqing said: "At that time, my subordinates and my father were just passing by there, and the piece was low in the middle and high all around, like a mountain col, but it was a big one, and there were a lot of black pebbles exposed on the ground. ”
