Chapter 31: Upgrading the Bonfire

Xia Hong knows how precious iron tools are in this world.

Iron ore itself is considered a rare resource, and in this world, even cutting down trees is incredibly difficult, let alone mining iron, which is even more advanced than wood.

Why do only medium-sized camps have iron tools?

Because without a strong person at the Earth-digging Realm, even if you discover iron ore, you can't extract it; and iron and coal are like a family, having only iron without coal, the heat produced by burning wood is not enough to smelt iron tools.

In Great Xia Camp over the years, only Xia Ding had half an iron tool—a stone axe—which was lost when Xia Ding was killed.

Moreover, Xia Hong also knows that Xia Ding's axe was exchanged for lots of wood with a familiar person from Rogel Camp's hunting team.

This shows that iron tools are not only rare but also strictly controlled by those medium and large camps, prohibiting them from going out.

How Da Shi Camp got their blades, Xia Hong is unsure.
