The frenzied energy filled the barrel, turning what was originally a white barrel into a purple one.
The massive heat even distorted the air around the barrel.
This time, the charging process took much longer, up to a full minute.
And the massive energy condensed from a light purple into a deep purple, and as the energy continued to gather, even the floating [Wolf King] began to shake unnaturally.
At the instant the machine reached its limit, Grey Wolf immediately pressed the fire button.
A thick beam of deep purple energy blasted out from the muzzle, carrying terrifying high temperatures, descending from the sky to strike the protective shield released by the [Devouring Demon Tree].
Overwhelming!
The silver protective shield didn't last even a second before twisting and shattering under the energy strike into fragments.
In the next moment, the residual power of the deep purple energy beam pierced through the three-times-thick protective tree roots almost instantly.
