Chapitre 69: A godly shot (1)

Xu Qi 'an slowly glanced at his colleagues' faces and said in a deep voice,"This is saltpeter."

The name saltpeter was very unfamiliar to the few martial artists present who had not read much and lacked relevant knowledge.

Song tingfeng exchanged glances with his colleagues and asked with a frown, ""Saltpeter?" he asked.

Xu Qi 'an thought about it and said,"I'll change the name so that you'll know more about it." It's the main material for making gunpowder."

Everyone's expression changed.

Gunpowder was a secret technique of Da Feng, and it was one of the means to intimidate the countries of the four Seas. As long as it was a formula or material related to gunpowder, Da Feng would have very strict control over it (mainly saltpeter).

Even a night watchman had a smattering of knowledge about the composition of gunpowder.
