Lin Fan knew that the black cavity armor could offset a large part of the pulling force caused by the collapse of the outer wall of the universe.
However, he didn't expect the Empire to have built so many Sun-class warships, even though they were only using the prototype of the black cavity armor technology.
Just like what he said to Artemis and Tarovis, what he didn't understand was how the Sun River Empire obtained so many black cavity crystals.
However, this wasn't a big problem.
Even if they couldn't use the surprise attack from the rear and the Alliance's main force to secure victory, the result would still be the same. However …
The battle changed from one phase to three, and it would take more time.
"Speaking of which, Gloucester probably thought that the Federation fleet was pressured by the Sun River fleet and chose to retreat, right?"
In the virtual conference room, Artemis, who knew about the three-phase battle plan, said with a relaxed smile. Tarovis also did the same.
"However, we can't be careless. Even though we have destroyed eighty percent of the supplies in the Sun River Empire's frontline, the remaining supplies are enough for them to fight for a month. If they are desperate, we will still win, but we will lose a lot!"
"That's right, we still have to fight back to the center of the universe. That's Amras's nest. Who knows what other tricks he has up his sleeve!"
After hearing Lin Fan's reminder, Artemis nodded in agreement.
"Then let's discuss how to deal with Gloucester when he goes crazy …"
-----
Just as Lin Fan and the other two were discussing the follow-up battle, the Federation fleet that raided the Empire's logistics fleet left through the black cavity channel.
Other than the cannon fodder at the front line, who were still fighting desperately, the war …
It seemed to have ended at this moment!
Gloucester, who finally had some free time, immediately began to deploy.
In every supercluster, at least a hundred billion warships had been mobilized. With every three warships as a unit and the maximum distance that could be accurately observed as the radius, a surveillance network made purely of warships had been established that covered every inch of the void.
These warships only had one mission, which was to observe the surrounding area all day long. As soon as they discovered the formation of a black cavity, they would immediately report it. Then, the headquarters would send out a fleet to destroy the passage before the enemy arrived.
Since the Federation had the technology to prevent him from detecting when he opened the channel, then he would use the most primitive method — visual inspection!
Of course, it was impossible to observe the universe visually. It could only be observed through the equipment on the battleship. If one wanted to observe without being affected by time, the observation range could not be too large.
Therefore, the number of warships required would be enormous.
Although this would reduce the manpower available by almost three trillion battleships, it was still necessary.
Otherwise, what would happen if the humans used this kind of undetectable black tunnel to launch another sneak attack in the next war?
However …
Just as Gloucester was planning all this, the Federation fleet that he thought had retreated was like a dagger stabbing into the heart of the Empire's army.
An hour later.
Sirens …
It rang again.
"What's going on!"
Gloucester quickly stepped into the bridge and shouted.
He had just finished all the preparations and was about to take a break. However, less than a minute after he left the bridge, the sirens rang.
Did the Alliance attack, or did the humans launch a sneak attack?
Logically speaking, it shouldn't be, right?
The Alliance still had trillions of cannon fodder battleships defending. Even if they were all lined up and waiting to be shot, it would take a few days!
It also didn't make sense for the humans to launch a sneak attack.
He had already used the most primitive method to monitor all the superstar clusters at the frontline. There was no chance for a sneak attack, right?
In short, with a stomach full of questions, Gloucester returned to the bridge again.
"Commander, it's our subsidiary civilizations. All the subsidiary civilizations adjacent to our frontline were attacked by the human fleet. According to the database, these fleets are the human fleet that launched a sneak attack on our rear!"
"In other words, they didn't retreat. They used the black cavity tunnel to attack these subsidiary civilizations!"
The adjutant ran to Gloucester with sweat all over his forehead and reported anxiously.
Although the Sun River Empire didn't care whether these subsidiary civilizations were destroyed or not, it still depended on the situation.
At least …
In such a situation, these subsidiary civilizations were the lifeblood of the dynasty's army!
Before the war of attrition between the mainland and the Federation came to an end, sending supplies from these civilizations to the frontline through the black cavity tunnel was the only safe and stable way.
Now …
The situation was really bad.
On the side …
After hearing the adjutant's report, Gloucester felt like he was struck by a bolt from the blue. He almost collapsed. Only three words kept echoing in his mind.
"It's over!"
He calculated all the situations and made targeted arrangements.
However, in the end, he missed the subsidiary civilizations behind the frontline!
Now, the plan of using these subsidiary civilizations to send supplies to the frontline through the cosmic currents was completely ruined.
No, it's not over yet. There's still a chance …
"Quick, contact the mainland immediately and report the current situation!"
"Yes, Commander Gloucester!"
Yes, there was still a chance … At least from Gloucester's point of view, there was still a chance!
As long as they won the war of attrition launched by His Majesty, they could reopen the channel to send supplies from the mainland to the frontline.
With the current reserves of the empire, the probability of success was quite high!
Gloucester clenched his fists as he kept telling himself this.

The center of the universe, the Sun River Empire, the Imperial Palace.
"We can't wait any longer. Immediately launch the war of attrition against the Federation with the dark crystals!"
"If they accept the war, the empire's reserves will be opened without restrictions until the war of attrition ends. If the Federation doesn't accept the war, then send supplies over!"
"Yes, Your Majesty!"
One of the guards responded and immediately went to pass on the order.
Amras looked at the intelligence minister, Harris.
"Harris, go to Garen's side again. To be honest, I'm still not confident in this war of attrition. Think of a way to show Garen how powerful we are and ask him to send us more black cavity crystals!"
"Yes, Your Majesty. I'll go now!"
