The test was successful. Li Yan and the others began to discuss battle strategies in earnest at the top of the city wall.
Li Yan first asked, "Is there a specific condition for the dust explosion? It can't just explode as soon as it's scattered, right?"
"Of course not."
Li Xuan shook his head and said, "The density of the flour is required, a minimum must be maintained for every——".
He was about to blurt out that every cubic meter of air should contain at least 9.7g of flour dust, but quickly realized it was inappropriate. Instead, he manipulated the Zhenyuan to throw up a portion of the flour, causing it to hang in the air.
"Roughly to this extent, it also can't be too dense, we need to ensure there is sufficient air within it. Furthermore, a fairly enclosed space is needed. However, we can create some pressure within the range covered by the dust through wind control. Finally, there must be a source of ignition of sufficient heat."
