Someone who seems to come from another world, an ability that looks unscientific but is actually very sci-fi, and a real world of brutal truths. Can it recover the historical documents of the past? Is all this the final, unyielding defiance of civilization?
Please read Relics of Civilization, also known as “From the start: You guys are all weaklings. My golden finger is the real deal (´◑д◐`).” Another world, industry, agriculture, technology, military, sci-fi, no female lead. Extremely toxic, do not enter if you are a bleeding heart. It may be humorous and funny. The protagonist is fixed, but no other character is: they may disappear at any time, and when they return is anyone's guess.
