After receiving Roger's reply, the Lord of the Fallen turned its gaze back to the Mana Cannon.
An unprecedented, strange aesthetic washed over it. The cannon body was three meters long and roughly two meters wide, with an overall square, sturdy appearance. Six barrels were arranged neatly in a row, their deep, dark muzzles evoking a feeling of... fear and the unknown.
These were actually the cannon's magical rails.
Roger and Betty had disagreed to some extent over the development of the "Super Big Gun." They had successfully created a super magical cannon capable of storing power and casting high-level magic—a scaled-up Ray Gun. It only needed mana infused into it to unleash magic with astonishing power.
However, this version of the Mana Cannon had an extremely short lifespan. It would be completely scrapped after firing at most ten shots, and its manufacturing cost remained prohibitively high.
Thus, their next idea was naturally quite simple: develop another Mana Cannon with somewhat less power than this one.
Betty's approach was simple and direct: cheaper materials plus lower-tier magic. But Roger had a different idea—the Mana Railgun before them.
It used mana in place of gunpowder to create a powerful magical propulsion mechanism, then fired shells with it... The one before them was a six-barrel Mana Railgun. It could also be separated or assembled into one-, two-, three-, four-, or five-barrel versions, or even seven-, eight-, nine-, or ten-barrel versions. None of that was a problem; the core logic remained sound.
However, it was worth mentioning that the larger the Mana Railgun, the greater the possible recoil. So Roger had added a fastening mechanism to secure it to the ground and ensure it would not overturn.
Once he confirmed that there were no issues—whether through the knowledge granted by the authority of
