Another year passed...
While the Black Plain Empire was secretly making progress with alien technologies, the Spiritual World was experiencing a technological boom.
Not only the powers involved in developing war technologies for the fate of the world were learning the alien methods. In addition to the powers most concerned with the survival of this world and its people's freedom, some organizations seized the moment for short-term financial gain.
Several blacksmiths, alchemists, array masters, etc., had been working with alien technologies for the past two years, but they weren't just trying to improve the world's powers. Many professionals used part of their knowledge to change pill formulas, array inscriptions, weapon models, and so on. Through these changes, better items became available to those with more resources.
