When Herad and his companions arrived at the weapons laboratory, the lightweight mithril plate armor components had already taken their rough shapes.
Arcane golems placed red-hot mithril ingots into the molds of the casting equipment, then started the machines to die-cast them into shape.
In fact, the finished products from this single-step die-casting process were already perfectly usable.
They were not much inferior to products forged through countless hammer blows.
That was how mass-produced armor was made.
Armor intended for important members certainly could not be made so casually.
The next step was precision forging.
The large hammers clanged, and the small hammers chimed.
That was the main rhythm of metal equipment manufacturing.
In the distant Assembly Workshop, a behemoth was undergoing final assembly.
The behemoth was a black cylinder.
Even lying horizontally on the ground, it was nearly twenty meters tall.
Its length exceeded sixty meters, a little taller than an eighteen-story building.
That enormous thing was the Heavy Energy Cannon.
Alleria and Sylvanas knew about the Heavy Energy Cannon.
But they had never imagined it would be so huge!
A behemoth like that required a very large hull to carry it.
Only the Obsidian Warship had what it took.
In fact, even mounting the Heavy Energy Cannon on the Obsidian Warship was awkward in terms of size.
It was a little too large to mount on the side of the hull as a secondary gun.
But mounting it at the bow as the main gun felt somewhat unworthy of the Obsidian Warship's tonnage.
At the current stage, however, only the main gun position suited it.
The Heavy Energy Cannon's primary material was obsidian.
Its Energy Runes were filled with mithril.
Gold could be substituted for this part, reducing costs and making it somewhat easier to manufacture.
