Herad finished making an obsidian tube ten thousand meters long and two hundred meters thick in just half a day.
Apart from its immense size, the thing had no complicated structures that required much thought.
It was like a building with its rebar and formwork already in place; all that remained was to pour in the concrete.
At most, a concrete vibrator needed to be inserted to distribute the concrete evenly and eliminate air bubbles.
The construction process was simple and posed no pressure at all.
But the finished building was merely a crude, unfinished shell, the kind without even a coat of white paint on the walls.
This long, thick obsidian tube was in much the same state.
It was not yet a super energy cannon.
Only after the Energy Runes were inlaid and the necessary external components installed could it be deployed on the battlefield.
So the work ahead would not be as easy as making the main body!
Of course, the arcane golems did most of the construction.
The densely packed Energy Runes on the tube walls had a total length of several million meters.
Even for the arcane golems, this was a major challenge.
But they were not working alone.
Herad had hired many earth elemental creatures to lend a hand.
Though the earth elemental creatures looked clumsy, they had no trouble transporting materials.
They could also handle the work of making mithril bars with forging equipment very well.
Their great strength and resistance to high temperatures allowed them to pick it up quickly.
They were the equivalent of helpers assisting craftsmen on a house-building project.
If the arcane golems were skilled workers, then the earth elemental creatures were laborers.
With skilled workers and laborers working together, construction of the super energy cannon progressed rapidly.
