Although the mecha has achieved mass production, the military metal minerals required to make the mecha are rare resources controlled by the state. Although private enterprises have the right to own production lines, they can only use some general metals. And the general metal, even the best quality titanium aluminum alloy, can only barely meet the needs of the old machine.

In a fortuitous experiment, an apprentice in a materials laboratory discovered that adding the powder of tooth grinding from tooth eaters to general metals increased the hardness of the metal by a notch. With the demonstration of generations of experts, the addition of the right amount of "biomaterial" in the metal smelting process can strengthen the strength of the metal to varying degrees in some aspects.

For example, adding tooth eater teeth can increase stiffness, and adding blood from bantam red-crowned lizards can improve toughness...... Even some high-level biomaterials can improve the performance of mechs to a level that the new elemental metal can't reach. "Biomaterials Science" has been slowly improved and has formed a mature theoretical system.

In order to achieve mass production of high-level mechas, private enterprises have purchased biological materials on a large scale, and the status of mercenaries has become higher and higher. Therefore, almost all mercenary teams now work part-time hunters to collect materials when there are no tasks.
