Chapter 421 Zero Hub

They made use of specialized subterranean exploration vehicles, designed for traversing complex terrain, a total of six vehicles, advancing through the narrow underground tunnels. These vehicles carried explosives in the center, with units 101 and 102 covering the rear, alert to potential attacks from the sides and behind.

Ratman Sentinels scouted deep in the underground, where Lila's magic power needed to be on the cutting edge. The three hired Rat Sentinels cleared the way for the main force, shuttling through narrow gaps, in search of signs of the Crystal People.
