Chapter 150: Trial Production of Cannons
Our Discord Server: .gg/PazjBDkTmW
Unlike the usual quiet, the atmosphere around the machinery department in Qingzhou City had grown tense in recent days.
Residents noticed a sharp increase in guards. The number of soldiers had multiplied, and each one wore full silver armor, exuding an air of cold authority. Anyone who even slightly approached the machinery department was immediately driven away.
Every person entering the department had to show a special pass and undergo inspection. Someone once tried to sneak in without a pass—and was severely beaten and thrown into jail on the spot.
All these strange changes made people wonder: What on earth is going on inside the machinery department?
Only Xiao Ming knew the full truth. That morning, he arrived at the gates of the department, handed his horse to the guard, and entered at just the right moment.
Inside, Chen Qi and his craftsmen were preparing to pour molten iron into a cannon mold.
While Qingzhou could now produce high-quality steel, not all steel was suitable for casting cannons.
In fact, even in modern times, until Krupp cannon steel was developed, cannon casting was limited to three main materials: copper, bronze, and iron.
Copper was the most straightforward—but also the most expensive. Given the limited mining output in Great Yu, using copper for cannons was like making golden toilets.
