"Don't let those sons of b*tches escape! Block them!"
Inside the warships, officers screamed themselves hoarse.
The primary purpose of these remaining warships was not to directly confront millions of enemy forces, but to block them.
Hundreds of thousands of warships launched energy from their main cannons, and these energies formed a dazzling high wall in the starry sky.
Mu Lei Bi looked at the high wall, and for a moment, he felt an insurmountable thought.
"It's space."
"This is a spatial high wall."
The energy warped the space there, a very large area, exceeding 8 cubic light-days.
This was equivalent to a giant cube with a side length of 346 astronomical units blocking their path.
Even if the Advancing Civilization and Flying Civilization's warships were dispersed, they couldn't traverse such a long distance. Most of their warships would have to go around, which would waste at least one day.
"Use space jumps to jump over it."
Human Civilization's understanding of the Advancing Civilization was actually relatively limited.
The Advancing Civilization's foundation in space was definitely higher than Human Civilization imagined.
The Advancing Civilization's warships initiated space jumps.
The Flying Civilization Fleet beside them was dumbfounded.
You jumped, what about me?
The Flying Civilization did not possess such technology; in fact, their warships were even slower than the Advancing Civilization's warships.
They fled in a panic towards the rear of the black hole.
When they saw the light, it actually meant that these energies were quite close to them.
The energy from the Type II Full Constellation Cannon also propagated at the speed of light, but because it still had some directionality initially, it would be slightly slower than some scattered photons.
But only slightly.
What was the exact distance?
About 8 astronomical units.
"Attack those Human warships and cut off their energy supply to the spatial high wall."
At this moment, this was the only way for them to escape as quickly as possible.
They flew while launching attacks towards the Federal Fleet.
The Federal Fleet's warships were destroyed on a large scale.
The spatial high wall gradually became lower.
This method was effective.
Before the Flying Civilization could rejoice, the energy blast created by the Full Constellation Cannon caught up to them, and they were submerged.
At the same time.
The Advancing Civilization's warships crashed into the spatial high wall.
Mu Lei Bi looked at the high wall, knowing that their judgment was wrong.
"This is a Dimensional high wall, not a spatial high wall."
This was a fundamental difference.
The utilization of space only created some spatial distortion, and did not involve crossing a dimension.
A dimension, that was something on another level.
The Advancing Civilization had not engaged with Human Civilization for too long, and the Flying Civilization could not possibly share all information with them.
This led to them being completely unaware that Human Civilization's research into dimensions had reached a certain stage, sufficient to incorporate dimensions into weaponry.
They broke through the Three-Dimensional spatial high wall; however, what now blocked their path was a Four-Dimensional high wall.
This high wall was so tall to them, an invisibly tall wall.
Their understanding of dimensions was weaker than Human Civilization's, which meant they couldn't see this high wall. Naturally, they couldn't cross it, and even now, they were lost beneath this high wall.
The Advancing Civilization's warships wanted to retreat, leave, or bypass this high wall, but they hit walls everywhere.
In Four-Dimensional space, they lost their sense of direction.
This feeling was like a person walking on a flat surface, who then stood on a sphere.
On a flat surface, a person can continuously walk around and measure the size of the space.
But on a sphere, if a wall is erected on the sphere, it doesn't need to encircle the sphere; just a small wall is enough. If this person keeps walking, they will always hit this wall.
To them, this space was already infinite.
They were trapped inside something like a Mobius strip. Sometimes, they might have already left the strip and reached the outside, but they didn't know it was the outside, which led to them constantly hitting walls.
"They are trapped."
"What if they're strong? They want to cross the peak of dimensions? They're still millions of years too early."
Seeing the Advancing Civilization trapped, everyone was overjoyed.
This time, they profited.
Hundreds of thousands of warships, trapping and killing millions, nearly 10 million enemy warships.
However, just over an hour later.
The black hole behind them was now crushing forward.
The gravitational radiation reaching the Dimensional high wall was also very strong.
The dimension was directly flattened by the gravitational collapse.
The Advancing Civilization's warships instantly "regained light."
"Damn it, why now!"
The Human officers on the warships observed the Advancing Civilization's warships in the distance starting space jumps again, and each of them was filled with disappointment.
They should have captured them all.
Could it be that even this wish was not allowed?
Immediately after, the energy from the Full Constellation Cannon reached them. The warships could not even last a minute against such powerful energy.
Type I, the most primitive Full Constellation Cannon, might have used ordinary energy.
But Type II, the composition of the energy largely transformed into creation particles.
