They helped the Demon Clan improve their weaponry and adjust the formula of gunpowder to achieve the ideal effect.
One should not underestimate these Dwarven scientists. As mentioned before, Dwarves are a subspecies of the Elf Race, with lifespans almost identical to Elves.

The High-peak Dwarves had adopted Earth's military technology for less than forty years. Forty years ago, Dwarven weaponry was similar to that of the Demon Clan, both possessing early long-range firearms and artillery.
