No crude oil? It couldn't be found for some reason, or there really wasn't any available?

From the period Emperor Roselle was assassinated till this day, about a hundred and fifty years have passed, and there are still no traces of crude oil…

Klein's pupils constricted as his hand quivered while holding the diary.

No crude oil not only meant that the future of the internal combustion engine became uncertain, it would also lead to a state of stagnation in the chemical industry. In other words, Earth's modern industrial age would never transpire here!

In short, the development of this world was uncertain to Klein.
