It was unclear whether the information about underground fissures and gem mines had been edited, but the library did indeed have no more detailed records. Aside from that, the frequent mining accidents from over a century ago were mentioned only in passing.
Xu Huo then found some numerical records in the data files. Over the period from roughly 150 to 120 years ago, more than ten thousand mining accidents had been recorded. Averaged out, that came to over three hundred a year—in other words, accidents had been happening almost every day in District 019.
The figure was frighteningly high by any measure. But after a new mining system was introduced 120 years ago, the accident rate plummeted. That meant that in the years just after Master Suolan was born, District 019 had begun to become a "perfect sub-district" in the truest sense.
Xu Huo looked further. The most deaths had occurred at the more than one hundred major mining companies in District 019. These companies controlled more mines, so not only were their accident rates high, but the number of people killed in each accident was alarming. Compared with small mines, a major mine that wasn't properly managed could cause a cave-in to spread far beyond its immediate area, especially with underground fissures nearby. It wouldn't be surprising if an entire mountain collapsed.
"Hey, brother, have you found any clues?" A Player from the library suddenly came over to him, holding a technical book about mining.
"Not yet." Xu Huo closed the file in his hands and asked in return, "What about you?"
The man smiled and patted him on the shoulder. "Don't be so tense. We're all in the same Dungeon."
As he spoke, he pointed to two other Players not far away in the library. "Looking for clues
