Back in early May, nearly two months ago, a messenger sent from the "Rock of Disaster" arrived at Nicolam, on the way to King Vincent, and secretly visited Professor Ainbecker. To get opinions on peat from a professor of paleontology.

"... hmm... it's called peat."

"Peat...?

"Hmm. It's been carbonized by plants for a long time, and it's similar to coal in that respect. Compared to coal, the era is still new, the petrochemical process is not sufficiently advanced, and it is shaped like mud."

Peat. Sometimes called grass coal or peat. It is believed that plant remains that have not been decomposed due to low temperatures have been deposited and are in the early stages of coal formation.

High moisture content, low carbon content, and low quality as a fuel, but still burning, make it a valuable fuel for countries like Theodrum with scarce combustible materials.

"As fuel....."

"Coal may be inferior to charcoal if it's not as good as carbon. But on the other hand, mining will be easier. We're not just digging it out. Well, it won't take much time to dry it."

"Don't you know how much firepower it will be?

"I'm sorry, I don't know. Because I'm out of my specialty. Well, there's a lot of stuff mixed up. You can't expect much."

"... anything else?

"As I said earlier, it's not my specialty. All I know is that it's a big deal... but there's gonna be smoke.... well, this is the same for coal."

"Smoke..."

"Isn't that why we should ask the soldiers we found? You've actually used it, haven't you?

Professor Ainbecker said that the opinions of real users were more valuable than anything else.

"Ah... no, I've seen him burn, even though he has experience. It seems that it was not used very much in my hometown.... probably because of the disadvantage of the professor."

"Hmm... the quality of the fuel isn't that high."

The envoy seems to have been thinking for a while.

"What about reserves?

"I wonder how much we have in reserve..."

This time Professor Ainbecker thought about it.

"... I can't be sure because I haven't seen the topography or geology of the site... but I don't think it's extremely local when I think about the causes of peat. Though it may be coarse, can we think of it as being somewhat widespread?... you (and more), given the uncertainty of dungeon... I can't say anything."

"Is it a dungeon..."

Anyway, it's a strange dungeon that turned into a rocky mountain overnight. It is not known how it affects the distribution of peat.

"When things become dungeons, they're getting out of my field of expertise."

"The more I become....."

Indeed, when dungeons are involved, the possibility of being different from the normal peat seam cannot be discarded. No, you should think that Ning is definitely different - the secret envoy agrees with me.... In fact, Crowe, the dungeon master - to be precise, Dungeon Road - didn't know anything about peat, so he didn't do anything about it... From Theodoram's point of view, I didn't think that the dungeon master, who caused so much trouble, was just sitting around talking about peat.

"Now we'd like to ask you about your professor's specialty. The peat ingredients obtained this time... or do you know what kind of plants are based on? Compared to the last fossil."

In response to this question, Professor Ainbecker has a troublesome look on his face.

"... I don't want to be taken away from you... but somehow, as you can see, it's decomposed... just..."

"Just...?

"As far as the remaining plant matter is concerned, the remains of grass like cedar can be identified.... I can't be sure about this either... but if you dare say so, the fossils you got last time don't seem to have the same kind of plants."

"... the place hasn't changed much?

"The place hasn't changed, but the times have changed. Probably tens of thousands of years, no, there's more to it than that."

"It's been tens of thousands of years..."

"I wouldn't be surprised if you said millions of years."

On a planet with a crow, the Coal Age ranged from 367 million years ago to 289 million years ago. If peat had been formed in the fourth century, it would have been about 1.7 million years ago. The difference does not end in a million years.

Well, actually, the fossils of the tree leaves we found earlier are not that old.

"If there is such a difference in the times....."

"The terrain and climate have changed a lot. Naturally, the plants that grow there are also different. It's not strange if the composition is different."

"The more I become....."

"So... bye. From the composition of peat, it is pointless to say the expected quality of coal."

"... I understand..."
