As for the Burning Legion taking the path of mechanization, Herad was not worried that they could produce anything worthwhile.
If they could pursue mechanization, the plant army could take the same route.
If the Burning Legion focused on improving defense, the plant army would improve its firepower.
The bigger the caliber, the greater the justice; the greater the numbers, the greater the justice.
This was the philosophy Herad instilled in the Black Mushroom Men engineers.
After seeing the Railway Gun, the Black Mushroom Men engineers firmly believed in this principle.
They searched the Fel Planet for the remains of the Burning Legion's heavy industry.
Then, under the goblin engineers' guidance, they converted them into heavy industrial facilities that suited their needs.
The main reason products of Goblin Engineering were unreliable was that their parts came from small workshops, with no guarantee of quality.
For example, a poor-quality gun barrel carried a certain risk of bursting when fired.
Using the Burning Legion's fel-powered processing facilities neatly solved this problem.
The felsteel smelted in the Fel Forge was far superior in quality to ordinary steel.
The enormous fel-powered forging equipment hammered away with a series of clangs, forging felsteel ingots into the rough shapes required.
The goblin engineers guiding the construction of the equipment from the sidelines both loved and feared fel, a filthy yet useful energy source.
Goblins had some resistance to fel, so brief contact with fel-powered processing equipment was not much of a problem.
But prolonged exposure would make their skin greener.
It would not cause bodily mutations from fel corruption as it did in the Draenei.
Even so, increasingly green skin was still unacceptable to the goblin engineers.
At the thought of their healthy green skin turning a dark green so deep it was almost black, the
