Apart from Ji Liuli, who had produced gunpowder, the others hadn't thought it through so meticulously. Their direction for improvement was only focused on how to mix the ingredients, how to achieve uniform granularity, and how to balance the properties.
Sun Yu then said, "So, to increase power, it merely comes down to expanding more greatly and burning faster. I've concocted a formula, slightly refining it."
Sun Yu then took a bit of gunpowder and added a spoonful of white powder to it before igniting it with Dao Power. With a loud bang, flames shot to the ceiling, the power at least half again as great as the original!
Wei Yuan's eyes lit up, but after asking for the formula, his spirits dampened. The spoonful of powder that Sun Yu used contained two quite expensive drugs; just the spoonful of powder was costlier than several stones' worth of gunpowder.
