The distance of tens of thousands of black cavity units, even Ninth Generation Black Hole Engine, would take more than a month to cross.
However, when the distance was reduced to within ten thousand Standard Black Hole Unit, and Trova Universe was included in the scanning range, Lin Yu was discovered.
The fleet over there is disappearing rapidly in an unknown way.
At this speed, I am afraid that all those fleets will disappear in less than half a month.
This is a very strange thing, because Lin Yu did not detect any signs of the other party opening the black cavity transmission channel, and those fleets were not moving, but suddenly disappeared.
This situation was immediately reported to Lin Fan, and Lin Fan passed the scan data directly to Luo Li.
If you don't understand the things in black talk, just ask Luo Li, you are absolutely right.
After all, Great Xia Federation was the most powerful civilization in the black cavity in tens of billions of years. As the former chief scientist of Great Xia Federation, Luo Li could definitely tell no matter what technology the other party used.
"You mean Cross-border Device?"
"Yes, it is Cross-border Device, used to cross the barrier of the Black Hole Cavity Realm and quickly move from one Black Hole Cavity Realm to another Black Hole Cavity Realm!"
"That's it, then I'll let Lin Yu continue to create pressure on them. If they want to go back, just let them go back. Time is on our side!"
After understanding the situation, Lin Fan nodded and said.
You must know that Azure Dragon Universe is a special universe. Not only does it have self-awareness, but at the same time, the civilization born in Azure Dragon Universe, both in terms of development speed and the evolution speed of life, is much faster than the civilizations of other universes.
Take Black Hole Lifeform as an example, look at the number of federations born every year, and then look at the Kunsa Realm's four empires.
Over tens of millions of years, only a few thousand good ones have been born.
This is the life advantage in Azure Dragon Universe.
That's why Lin Fan said that time is on the side of mankind.
Although now it is possible to send Balu's army directly to Trova Universe through the black cavity transmission technology.
After all, it only takes ten days to intercept one-third of White Church's fleet.
But Lin Fan doesn't want to do that.
Because today, in terms of the combat power of battleships alone, White Church's battleships are no weaker than those of the Federation, and they are the real main fleet, 100% main battleships.
And what about yourself?
A mixed fleet, with 40% main battleships and 60% secondary battleships.
Yes, through the speed advantage and Black Hole Lifeform's proficiency advantage, the alliance can indeed defeat those ten White Church legions.
But it doesn't come without a price.
Therefore, Lin Fan also thinks that the other party's withdrawal is quite good.
If they want to leave, then let them leave. After a hundred or two hundred years, the Federation will definitely have the strength to crush them. After the Kunsa Realm is unified, Lin Fan will naturally command the two universes of White Church and Black Church.
There is no need to pay a huge price to kill one-third of the opponent's fleet now, right?
However.
Although Lin Fan's logic is correct, Luo Li has a different view.
"Lin Fan, what if I tell you that I can't make Cross-border Device now?"
"Is it a problem with the materials?"
"No, it's not materials. What Cross-border Device needs is not difficult to find, and there are many alternative materials!"
"What's the problem?"
Lin Fan is a little confused.
After all, Luo Li mastered all the technologies that Great Xia Federation had, but it was indeed impossible to manufacture. This made Lin Fan immediately think that it was the same problem as Black Hole Cavity Teleportation Device, lacking necessary and irreplaceable materials.
However, Luo Li said this was not the reason.
So, since the technology and materials are available, why does Luo Li say it can't be made?
"The manufacturing problem of Cross-border Device is not about technology or materials, but"
"The problem is that the Federation currently does not have Seventh Tier Black Hole Lifeform!"
What level is Lin Fan now?
Fourth Tier!
In addition to Lin Fan, Lin Yu and Galon are currently at this level.
Of course, they are worse than Lin Fan.
After all, Lin Fan has reached the peak of Fourth Tier and is preparing to enter Fifth Tier, while Lin Yu and Galon are only in the middle of Fourth Tier, and there is still a long way to go before the peak.
But even so, Lin Fan is still far from the Seventh Tier mentioned by Luo Li.
"There are two types of Cross-border Device. One is like a star gate. Build a Cross-border Device in two realms and connect them to each other to achieve the effect of fixed-point two-way transmission."
"The other type is one-way Cross-border Device. Although this type cannot be transmitted in both directions, and can only specify a certain Black Hole Cavity Realm, it cannot be accurate to a specific coordinate within the territory. To put it simply, it is one-way Cross-border Device that is randomly transported within the area."
"Judging from the situation of the Teli Empire, it must be the first Cross-border Device I mentioned. In other words, there is a Cross-border Device in the Teli Empire, and there is also a White Church!"
"Coupled with the current evacuation action of White Church, Cross-border Device of the Teli Empire must be in Trova Universe!"
"Lin Fan, think about it, if you were White Church and you knew you couldn't defeat the alliance and retreated, what would you do with the Cross-border Device in the Teli Empire?"
After giving Lin Fan some popular science, Luo Li asked.
"I understand what you mean. White Church will completely destroy the Cross-border Device in the Teli Empire after complete evacuation to ensure that we cannot pursue the Black Hole Cavity Realm where they are."
"And if we want to make Cross-border Device ourselves, we have to wait until I reach Seventh Tier, but I don't know how much time it will take, maybe even hundreds of years!"
"Then, without the device of the Teli Empire, within this period of time, even if we unify Kunsa Realm, there will be no way to expand to other universes!"
"Therefore, in order to avoid this situation from happening, even if it costs some money, we must arrive before White Church is evacuated and seize the device!"
After listening to Luo Li's popular science, Lin Fan understood it instantly.
Indeed, this device must be taken down, otherwise it will delay the Federation for at least hundreds of years.
You know, if every second of every day is very important, after all, Azure Dragon Alliance still has those powerful sweepers who don't know when they will arrive.
Therefore, being delayed for at least hundreds of years is absolutely not allowed to happen!
"Luo Li, based on the scanning data sent by Lin Yu last time, can we determine what the scanning range of the black cavity of this White Church battleship is?"
After thinking about the combat method for a while, Lin Fan asked.
"There is no need to judge this. Before a God-tier Civilization understands the black cavity Black Hole Cavity Particles folding reflection technology, the maximum scanning range of a Black Hole Cavity Space will never exceed one hundred Standard Black Hole Unit."
"And as far as I know, the weakest civilization that can understand this technology is many times more powerful than White Church!"
"Of course, the Federation is great because..."
"I exist!"
