Chapter 469: Cleaning out the Vermin

The moment the Cyclops Rats came within view, I unleashed my blazing arrow. Alnasl struck the front of the horde and then exploded, engulfing the vanguard in furious flames.

And then something unexpected happened. Now that I thought about it, I should have expected it, but I was being stupid. Come on, I am an arts student (not literal art, but in terms of humanities, such as literature and history), not a science student. How was I supposed to know what would follow?

In any event, the explosion triggered a chain reaction. Let's just say there's a lot of methane in the sewers, and the sewage itself is highly inflammable. A single spark onto the damned sludge was all that was needed to ignite the entire thing. The sewage spontaneously combusted, turning into an immense inferno that swept across the innards of the sewer and consumed the poor swarm of Cyclops Rats ravenously.
