The Blood Skull Arena's recruit training camp was a foundry workshop in another sense.
Countless rat people, whose homes had been destroyed and whose bodies burned with hatred, had gone through a life-and-death struggle in the dark dungeon. They had vented the hatred that should have been vented on the warriors of the clan on each other.
After layers of screening, the rat people who could still climb up to the ground and join the recruit training camp had all become the best "steel billets."
There, they could enjoy ten times more food than in the depths of the dungeon.
They could also apply secret medicines that had been added into the totem beast ointment.
Not only could that speed up the healing of wounds, but that could also make their bones as tough as steel and their flesh as tough as shields covered with leather.
Then, they threw themselves into the cruel training day and night.
