The main body of the Alchemical Cannon was a hollow metal cylinder, surrounded by three metal prisms as supporting braces, placed on a rotatable base resembling a millstone, and covered with densely packed, complex inscriptions.
To ordinary people, these inscriptions were like advanced math problems; just a glance at the symbols could make one's head spin and feel dizzy, as if staring at something indescribable, almost to the point of madness.
But to those who could understand them, the inscriptions on the Alchemical Cannon were actually quite simple.
"Let me see... Um, the city guard was right, there's nothing wrong with the overall structure of the cannon, the gunpowder is dry, and the crystal sand is very pure... As expected, the problem lies with the priming inscription," Ian remarked.
