Before the Human Fleet could respond, the Cleaners Civilization's planetary fortresses plunged headlong into the two dimensions starry sky.
They did not ascend into four dimensions. Instead, they entered the battle in their normal state!
Gravity shielding disengaged!
Immensely powerful gravitational fluctuations radiated from around the planetary fortresses!
Some of the planetary fortresses unleashed gravity comparable to that of quark stars!
The others had already become deep, fathomless "black holes"!
The gravity around them was so immense that not even light could escape!
Just how much destructive power would thousands of quark stars and small black holes have as they rampaged through a region spanning a hundred light-years?
Now, Human Civilization knew the answer.
Countless wrinkles appeared in the previously flat starry sky painting!
Gravity from three dimensions easily crossed the dimensional gulf and acted upon the two dimensions space.
This powerful, chaotic gravity brutally churned up the internal structure of the starry sky giant painting!
Inside the Earth.
Watching the starry sky painting ripple with folds and even begin to warp and twist in the holographic projection, Lü Yongchang's eyes filled with shock.
"Quark stars!"
"Just how much dense material did the Cleaners Civilization use to build these planetary fortresses?!"
In theory, to preserve a starship's maneuverability, dense material would normally only be used in its outer armor.
But the planetary fortresses before him clearly had not followed that conventional design philosophy.
Lü Yongchang had reason to suspect that over fifty percent of their volume was filled with dense quark material.
And those were only the quark fortresses!
In the black hole fortresses that had already become deep, fathomless black holes, the proportion of dense material could only be even more terrifying!
They even had to employ additional methods to increase the distortion of space around themselves!
Only
