After calming Murong Jiu down, Jun Yuyan immediately wrote a letter and had the Hidden Guard personally deliver it to General Fu.
He would not question the authenticity of the "fire-thunder" mentioned by Ah Jiu, as it had been proven that Ah Jiu had an exceptional understanding of certain matters.
At the time when the iron mine was discovered in Tea Ridge County, Ah Jiu's reaction had been exceedingly excited.
Moreover, he also knew that Ah Jiu had secretly instructed Manager Chai to purchase saltpeter.
Saltpeter was not as difficult to buy as ironware since fireworks and firecrackers required saltpeter, and nowadays, Taoists also used it in their quest for eternal life through alchemy, so it was not as tightly controlled as ironware.
Gunpowder also employed saltpeter, but it had not been used in the military, and its power was not considered very strong.
The "fire-thunder" mentioned by Ah Jiu had the potential for power tens or hundreds of times greater than that of gunpowder.
