To carry out this battle plan, the most important thing was speed.
After all, the Noreya Empire's Cross-Realm Technology was more advanced than the Federation's, especially in terms of energy supply.
Therefore, the Federation did not have much time.
Lin Fan could not open a Cross-border Channel to the Lyle Realm himself. Otherwise, the moment the channel formed, the Noreya Empire would likely discover it.
Moreover, even if there were a way to keep them from discovering it, the Federation's Cross-Realm Technology was weaker than the Noreya Empire's, meaning transit time would naturally be longer.
That meant the cross-realm operation had to begin even earlier.
For example, if the Noreya Empire opened its Cross-border Channel a year ago and attacked the Kadi Realm.
Then the Federation would have needed to open theirs two years ago for it to be possible.
But that created two problems: one, they could not accurately determine when the Noreya Empire would attack; two, they could not determine where the Empire would open its channel.
Whether they arrived too early, too late, or arrived but were too far from Norea's Cross-border Device, any of those outcomes would directly cause the entire operation to fail.
So, after careful consideration, Lin Fan finally settled on a bold tactic: directly making reverse use of the Noreya Empire's Cross-border Channel.
That way, after passing through the Cross-border Channel, the fleet would appear directly near the enemy's Cross-border Device.
And all that remained was a matter of time.
As mentioned earlier, the Noreya Empire's Cross-Realm Technology was more advanced than the Federation's, particularly in energy supply technology.
Thus, they could construct an enormous Cross-border Channel. Even a full thousand legions could all enter the channel in just one day.
Therefore, Lin Fan likewise had only one day.
