In order to prevent similar incidents from happening again.
In addition to those built by the Federation itself, there are also the original Knox Empire and Dasaross Empire Black Hole Gate.
Lin Fan even destroyed those Black Hole Gates within the federal 3000 Black Hole Cavity Realm distance, which were the Black Hole Gates of the group of sweepers that were destroyed before.
I understand clearly, after facing an eighth-level Black Hole Civilization, Lin Fan doesn't want to have a head-on confrontation with him right now.
After all, in terms of technological strength, they are at the same level as Luo Li.
The most important thing is that the Federation is only a theoretical eighth-order Black Hole Civilization, and Tianshu Church is indeed an eighth-order Black Hole Civilization.
Therefore, to make up for this gap, Lin Fan will need more time.
And destroying these Black Hole Gate is the first step for Lin Fan to buy time.
As for the second step, it is to build an isolation zone for the alliance while Tianshu Church will not be able to come over for a while.
Close the country!
As for how to establish an isolation zone?
In fact, it is very simple, just destroy the entire Black Hole Cavity Realm in the most brutal way.
You must know that there is Black Hole Gap between the Black Hole Cavity Realm and Black Hole Cavity Realm, and the essence of Cross-border Channel is to open a temporary gap in the boundary wall of the two Black Hole Cavity Realm, and at the same time establish a channel in Black Hole Gap to connect the two gaps for the fleet to pass.
Back then, when the Federation encountered the first sweeper, Knox Empire, it used anti-travel tactics. While the enemy was still in Cross-border Channel, it destroyed its Cross-border Device to cause the passage to collapse.
Then, the Knox Empire fleet, which had not yet reached the target Black Hole Cavity Realm, was directly exiled in Black Hole Gap due to the collapse of the channel.
In Black Hole Gap, living things cannot survive, and even Black Hole Lifeform can only survive temporarily.
Therefore, what Lin Fan has to do is to directly destroy a circle of the Black Hole Cavity Realm in the designated area Outer Domain, so that Tianshu Church cannot rely on Cross-border Channel to enter the area designated by Lin Fan.
It's like there are three stones in a straight line at equal distances on a river. When you cross the river, you can jump across the stones one by one, but if one day, the middle stone disappears.
Sorry, you can't cross the river because the distance between the first and third stones is too far for you to jump across.
The method Lin Fan wants to use is similar to this idea.
Of course, it doesn't mean that there is really no way to do this. There are still ways, and the answer is...
Realm Folding System.
However, this technology is unique to the Federation. In the entire Black Hole Cavity Space, only the Federation has this technology.
In other words, after the country is closed to the outside world, outsiders cannot come in, but if the Federation wants to leave one day, there will be no problem at all.
As for how to destroy Black Hole Cavity Realm.
This is about the way Black Mang Empire destroyed the black cavity fault during the early Kunsa Realm civil war.
As mentioned before, there are countless Fault Spaces in each Black Hole Cavity Realm, and these Fault Spaces are like the foundation of the Black Hole Cavity Realms. Once too many are destroyed, it will cause the collapse of the entire Black Hole Cavity Realms.
Therefore, it is not a big problem if you really want to destroy a Black Hole Cavity Realm. No one has done this before. That is because after destroying it, you continue to hinder others and hinder yourself, right?
However, the Federation, which possesses boundary wall folding technology, does not care about this.
——
Federation Year 6780.
The Sixth Route Army Expeditionary Force has completed its set combat objectives and completely eliminated the six sweepers.
At the same time, due to the fact that the black doors of the Kunsa Realm, the original Norei Empire and the original Dazaros Empire have now been dismantled, the Sixth Route Expeditionary Force can only follow Lin Fan's order and use the boundary wall folding system to return.
Federation Year 6825.
When the last expeditionary force returned to Alliance territory, the quarantine plan was officially launched.
Limiting the distance of 1,000 Black Hole Cavity Realm, the outer 38,798 black cavities are classified into isolation zones by Lin Fan.
And these Black Hole Cavity Realm that have entered the isolation zone list mean
Destruction!
In order to complete this plan, the alliance sent out almost all fleets and divided them into 38798 fleets. Each fleet was responsible for destroying one Black Hole Cavity Realm.
Even if it is.
There is civilization in this Black Hole Cavity Realm.
Talk about sympathy?
Talk about morality?
None of this means anything in the face of the fate of our own civilization.
Rather, if the leader of civilization talks about this all day long, then this civilization will definitely not survive three episodes in Black Hole Cavity Space.
Federation Year 6898.
The last Black Hole Cavity Realm on the isolation belt was successfully destroyed.
Since then, with the alliance territory as the center, 1,000 Black Hole Cavity Realm have radiated outward, with a total of 1,375,688 Black Hole Cavity Realm internally.
Total isolation.
According to Lin Fan, that is
The Federation must concentrate on development for ten thousand years!
——
Federation Year 6925.
Thousands of the Black Hole Cavity Realm away from the federal mainland.
Drew World.
A huge fleet came here.
They had not planned to stay, but were preparing to move on, but at this moment they had to stop.
"Jiang Yuntian Cardinal Archbishop, according to our detection, the Black Hole Cavity Realm in front is gone."
"No more, what do you mean no more?"
As the red archbishop of Tianshu Church and the son of Jiang Hai, Jiang Yuntian is the supreme commander of this Holy See expeditionary force.
There are a million legions, and they are all Eighth Order Peak's Black Hole Civilization battleships.
With such terrifying combat power, Jiang Yuntian is full of confidence in this expedition. To him, this is simply an armed outing.
However, after running more than half the distance, I almost crossed from one end of Black Hole Cavity Space to the other.
But his subordinates told him that they could no longer move forward?
What kind of joke is this?
Moreover, the reason is that the black accent in front is gone?
This was the first time he heard such a strange reason.
"Although we don't know the reason, the Kali Realm in front of us is indeed gone, so we can't advance from this route and can only take a detour."
"Then hurry up and do it. Damn it, this detour will waste nearly a year!"
After understanding his subordinate's explanation, Jiang Yuntian said impatiently.
——
Federation Year 6937.
After more than ten years and dozens of detours, everyone was dumbfounded.
Not only is the original Kali Realm gone, but all the Black Hole Cavity Realm leading to the Heretics territory.
All gone!
It's like Heretics has set up a moat in their territory Outer Domain.
No passed roads could be found at all.
Isn't this Heretics a thousand Black Hole Cavity Realm?
All Black Hole Cavity Realm that can lead to their territory have been destroyed, right?
Involuntarily, such a crazy idea popped up in everyone's mind.
