"Your Majesty, please look, this is the cannon that this humble servant has developed!"
Zhan Liang spoke excitedly to Zheng Yi, with several officials from the Ministry of Industry and Lei Shitou standing beside him.
Everyone's faces showed signs of fatigue, clearly they had been working continuously on the tasks Zheng Yi had given them.
But Zheng Yi's expression was a bit odd.
The cannon before him... or rather, calling it a cannon barrel would be more appropriate.
The whole structure is indeed round, cast from refined iron, fixed on the ground, slanting towards the sky.
However, the barrel was quite thick, about a meter in diameter, looking ominously dark.
Zhan Liang said, "Your Majesty, we have tried before, loading gunpowder and an iron ball into this barrel, simply ignite the gunpowder, and within ten breaths, the gunpowder explodes inside the barrel, thereby blasting the iron ball out."
Zheng Yi's mouth twitched, is this really a cannon?
An oil drum bomb?
