Clang——
Clang——
In a secluded corner of the back mountain, a seemingly young boy appeared to be scraping something with a whetstone in his hand.
He casually used a wooden stake as a workbench, throwing various metal parts onto the table, including triggers, springs, lacquer, black powder, talisman papers, and small, exquisitely carved metal tubes.
A bowl and a pestle were on the table, grinding innumerable granular fragments into powder.
Potassium nitrate seventy-five percent, charcoal fifteen percent, sulfur ten percent, mixing while constantly stirring to blend them evenly. In any era, as long as these three things are mixed in proportion, they can unleash quite a frightening power. Yet, in this era, people still haven't evolved to the age of firearms.
Because the most important thing couldn't be resolved.
Which is potassium nitrate.
"Just spent two days out fiddling with these things?"
A calm and cool voice came from behind.
