On his way, Meng Chao saw quite a number of citizens sitting at their entrances and polishing the monster bones in their hands. They were making the monster ribs and femurs into daggers, blades, and other tools.
Many of the monster bones were tough and malleable. They had the different functions of metals.

Fortunately, Dragon City had too much labor power, so they decided to ask the citizens who were idling in their houses to go through simple training and handle this sort of stuff.
