Almost all the energy of this four-dimensional shock wave was concentrated along the fourth axis.
As a result, it was not particularly lethal to four-dimensional objects or four-dimensional beings, but its lethality against Lower Dimension entities was staggering.
The reason was simple: Lower Dimension entities had no ability whatsoever to withstand fluctuations along the fourth axis.
It was like a sheet of paper, which was difficult to pull apart but easy to tear.
This was the principle behind the lethality of the Four-Dimensional Shock Bomb and four-dimensional spatial oscillations.
It was also the only weapon currently exclusive to the Earth.
Unlike the Four-Dimensional Shock Bomb, which unleashed its power in an instant, four-dimensional spatial oscillations delivered sustained, high-intensity attacks, inevitably requiring an immense supply of energy!
The Chiyou Planetary Fortresses could certainly meet that requirement, but modifying them would take considerable time and resources.
For Human Civilization as it stood, time was the greatest luxury of all.
The four-dimensional shock wave rapidly spread outward.
The Lower Dimension beings hurtling toward it stopped their charge the instant they encountered the shock wave.
Clumps of threads and scrolls twisted incessantly in the starry sky, as though struck by some invisible attack.
After holding out briefly, the cores inside these Lower Dimension beings quietly disintegrated, and dimensional ascension reactions followed.
The deaths of so many Lower Dimension beings alerted the surviving members of the Gardener Faction to the problem.
Only four dimensions could counter four dimensions!
They swiftly changed formation, placing the few thousand remaining four-dimensional beings at the forefront to shield the Lower Dimension beings behind them from the four-dimensional shock wave.
But...
As the flagship into which Human Civilization had poured countless efforts, the Earth naturally had more than just four-dimensional attacks at its disposal.
Under the cover of countless
