The distance of tens of thousands of black cavity units would take more than a month to cross even with the ninth generation black cavity engine.
However, when the distance was reduced to within 10,000 standard black cavity units and the Trowa Universe was included in the scanning range, Lin Yu discovered.
The fleet over there is disappearing rapidly in an unknown way.
At this rate, all those fleets will disappear in less than half a month.
This was 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 reported to Lin Fan immediately, and Lin Fan passed the scan data directly to Luo Li.
If you don't understand something in the dark side, just ask Luo Li, it's absolutely right.
After all, the Daxia Federation was the most powerful civilization in the black community for tens of billions of years. As the former chief scientist of the Daxia Federation, Luo Li could definitely tell no matter what technology the opponent used.
"You mean the cross-border device?"
"Yes, it is a cross-border device. It is used to cross the barrier of the black cavity boundary and move quickly from one black cavity world to another!"
"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 the Canglong Universe is a special universe. Not only does it have self-awareness, but at the same time, the civilization born in the Canglong Universe is much faster than the civilizations in other universes, both in terms of development speed and the evolution speed of life.
As for the black cavity life forms, look at the number of births in the Federation every year, and then look at the four major empires in the Kunsa realm.
Over tens of millions of years, only a few thousand have been born, okay?
This is the advantage of life in the Canglong universe.
That's why Lin Fan said that time is on humanity's side.
Although now it is also possible to have Balu's army be sent directly to the Trohua Universe through the black cavity teleportation technology.
After all, it only takes ten days to intercept one-third of the White Holy See's fleet.
But Lin Fan didn't want to do this.
Because when it comes to the combat power of battleships alone, the battleships of the White Holy See are no weaker than those of the Federation, and they are the real main fleet, 100% the main battleship.
And what about yourself?
A mixed fleet, with 40% main battleships and 60% secondary battleships.
Yes, through the speed advantage and the proficiency of the black cavity life, the alliance can indeed defeat the ten legions of the White Holy See.
But it doesn't come without a price.
Therefore, Lin Fan also felt that it was good for the other party to evacuate.
If they want to leave, then let them go. After a hundred or two hundred years, the Federation will definitely have the strength to crush them. After the Kunsa world is unified, Lin Fan will naturally command the two members of the White Holy See and the Black Holy See.
universe.
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 create a cross-border device now?"
"Is it a problem with the material?"
"No, it's not materials. It's not hard to find the ones needed for cross-border installations, and there are many substitute materials!"
"What's the problem?"
Lin Fan was a little confused.
After all, Luo Li had mastered all the technology of the Daxia Federation, but it was indeed impossible to manufacture it. This made Lin Fan immediately think that it was the same problem as the black cavity transmission device, lacking necessary and irreplaceable materials.
However, Luo Li said that was not the reason.
So, since the technology and materials are available, why does Luo Li say he can't make it?
"The manufacturing problem of cross-border devices is not about technology or materials, but..."
"The reason is that there are currently no seventh-level black beings in the Federation!"
What level is Lin Fan now?
The fourth level!
In addition to Lin Fan, Lin Yu and Jia Long are currently at this level.
Of course, they are worse than Lin Fan.
After all, Lin Fan has reached the peak of the fourth level and is about to enter the fifth level, while Lin Yu and Garen are only in the middle of the fourth level, and there is still a long way to go before the peak.
But even so, Lin Fan was still far from the seventh level mentioned by Luo Li.
"There are two types of cross-border devices. One is like a star gate. A cross-border device is built in two realms and connected to each other to achieve the effect of fixed-point two-way transmission."
"The other is a one-way cross-border device. Although this kind of device cannot transmit in both directions, and can only specify a certain black cavity boundary, it cannot be accurate to a specific coordinate within the territory. To put it simply, it is a random number within the area.
One-way cross-border device for transportation.”
"Judging from the situation in the Terry Empire, it must be the first cross-border device I mentioned. In other words, there is a cross-border device in the Terry Empire, and the White Holy See also has one!"
"Coupled with the current evacuation action of the White Holy See, this cross-border device of the Terry Empire must be in the Trohua universe!"
"Lin Fan, think about it, if you were the White Holy See and you knew you couldn't defeat the Alliance and retreated, what would you do with the cross-border device in the Terry Empire?"
After giving Lin Fan some popular science, Luo Li asked.
"I understand what you mean. After the White Holy See completely evacuates, it will completely destroy the cross-border device in the Terry Empire to ensure that we cannot pursue them in the Black Cavity World."
"And if we want to make our own cross-border device, we have to wait until I reach the seventh level, but I don't know how much time it will take, maybe even hundreds of years!"
"Then, without the device of the Terry Empire, within this period of time, even if we unify the Kunsa world, 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 the White Holy See evacuates and seize the device!"
After listening to Luo Li's popular science, Lin Fan understood 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, the Canglong 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 judge the scanning range of the black cavity of this White Holy See battleship?"
After thinking about the fighting method, Lin Fan asked.
"There is no need to judge this. Before a god-level civilization understands the black cavity particle folding and reflection technology, the maximum scanning range of the black cavity space will never exceed one hundred standard black cavity units."
"As far as I know, the weakest civilization that can understand this technology is many times more powerful than the White Holy See!"
