On a stretch of grassland between Gengxin City's old and new walls, the Water Dragon Cannon sat off to one side, facing the Hermit's Wall—a magical artifact refined by Lou Gao—five hundred meters away.
After Lou Gao further upgraded it, the artifact's defensive power could now withstand attacks from Soul Sages whose offensive capabilities were not particularly outstanding, even after they activated their Martial Soul Avatars.
However, there was currently only one of them. In terms of artifact-refining techniques, aside from Mo Lin, Lou Gao, and possibly Qiuniu, no artifact refiner could perfectly replicate it, making mass production impossible.
As the sound of compressed air came from within the Water Dragon Cannon, a water shell howled out from its muzzle. Its trajectory was remarkably straight, with barely any visible arc, and it struck the Soul Power wall with precision.
After rippling briefly, the struck surface of the Soul Power wall quickly returned to calm. Clearly, the Water Dragon Cannon's attack was still quite a ways off from Soul Sage level.
After several rounds of testing, the Water Dragon Cannon's effective range was five hundred meters. Its range was somewhat short compared to many modern weapons, but compared to the attack range of most Soul Masters, it was already absurdly overpowered.
Even for Title Douluos, if they stood still and continuously attacked, most of their attacks only reached a little over a hundred meters.
The Water Dragon Cannon's maximum power was equivalent to the fourth Soul Skill of most assault-type Soul Masters. Viewed as a standard-issue weapon, it was already quite good. It would have no problem dealing with ordinary soldiers or demolishing enemy structures, and its stable trajectory made it easy to aim without easily missing the mark.
However, as an entirely new attempt, it obviously had glaring shortcomings—namely, its
