There were only two ways to destroy the Black Cavity channel.
One was to create a Black Cavity Particle Disruption Device and send it into the channel before activating it to destroy it from the inside.
The other way was to open another Black Cavity channel and set the exit at the exit of the Black Cavity channel that was to be destroyed. In the end, the channel that could not supply enough energy would be destroyed.
With the current situation on the battlefield, with the obstruction of the biological civilization army, it was obviously impossible to use the first method.
Naturally, the Federation could only use the second method.
However, just as Lin Fan predicted, after half an hour, a large number of biological civilizations' armies flew out of the three Black Cavity channels one after another, the Federation still could not destroy them.
Each of these three giant Black Cavity channels was more than three times the diameter of the previous ocean current, so the speed at which Ipnos transported troops to the battlefield was directly increased by about ten times.
This made the situation on the battlefield delicate.
"No, we have to find a way to destroy the channel. Otherwise, with the current troop transport rate of Ipnos, in a few days, the second line of defense will no longer have any military advantage. After that, they will gradually fall into a military disadvantage!"
"But, based on the current situation, Ipnos has enough dark energy crystals. It will be very difficult to destroy the channel using this method!"
"Then organize a suicide fleet to break in and find an opportunity to send the Black Cavity Particle Disruption Device in!"
"That's what you say, but their defense is too tight. It's simply unrealistic for individual fleets to break in!"
In the virtual war room, watching the real-time battle situation, Artemis and Vitalos spoke one after another, but in the end, they still could not come up with a feasible plan.
"Let the Federation's Black Armor Fleet handle it!"
Listening to the discussion between the two, Lin Fan, who had not spoken before, spoke at this moment.
The two knew about the Black Armor Fleet and understood that it was the fleet with the strongest defense in the entire Cang Dragon Universe.
If it was this fleet, it seemed …
It was indeed possible!
However, there was also a big problem here.
Although the black-armored fleet's defense was powerful, their attack power was mediocre. The most important thing when breaking into the enemy's formation was attack power. If the attack power was strong enough, it would undoubtedly be difficult to break through.
"Mobilize three God-battling Squads and three peak-level Dark Energy Envoys. Deploy them on three Hongmeng battleships and move together with the Black Armor Fleet!"
"The Hongmeng warship and the God of War team will open the way forward. The Black Armored Fleet will protect us from the outside, and the Peak Dark Energy Envoy will stay in the warship and be prepared to deal with any unexpected situations!"
Looking at the expressions of the two, Lin Fan, who also knew that the black-armored fleet's attack power was insufficient, added again.
"Let's take a gamble. There's no better way anyway!"
"Okay, we will start deploying God-battling Team and peak-level dark energy users immediately. When will the Federation's black-armored fleet arrive?"
The two of them looked at each other and nodded, agreeing with Lin Fan's suggestion.
After all, there was no better way.
"It takes about half an hour to get here through the black passage!"
-----
Half an hour later.
All the fleets and personnel participating in this battle had gathered behind the second line of defense. They were divided into three assault fleets. Each fleet was equipped with 33 million black-armored warships, a Hongmeng warship, a full God-battling Team, and a peak-level Dark Energy Envoy.
Although there were not many warships, their combat power was definitely strong. If it was in the previous war with the Sun River Empire, the power of each fleet would be able to kill their way through the trillions of Empire's warships.
Among them, the fleet dealing with the second black passage was the commander of Sophia's fleet. The peak-level Dark Energy Envoy in the warship was also a member of the Federation.
Speaking of which, this was Sophia's son-in-law, Lin Yu.
Although his progress was not as fast as Lin Fan's, as the Federation's most powerful Dark Energy Envoy, Lin Yu had also touched the threshold of a new realm. It was about the same level as Lin Fan ten years ago.
With Lin Yu in charge, Lin Fan was not worried at all. Even if Ipnos came personally, Lin Yu was very confident that he could take him down.
"Commander, the command center has sent the order to attack!"
"Understood. Order the fleet to attack immediately. The black-armored fleet will use the Hongmeng warship as the center and deploy a dense defense formation!"
"Yes, Commander!"
"Little Yu, if something uncontrollable happens, I'll have to rely on you!"
"Don't worry!"
After ordering the fleet to set off, Sophia turned to Lin Yu and said.
After all, she had to rely on a mere 33 million warships to attack an army made up of countless powerful creatures.
To be honest, even Sophia, who was known as the most reckless commander in the Federation, was not confident.
However, with Lin Yu around, she felt much more at ease. After all, she knew how terrifying Lin Yu's combat power was now.
Very quickly, the three fleets crossed the Federation's second line of defense from different directions and advanced towards their targets. When the fleets on the line of defense attacked, they deliberately avoided the routes of the three fleets.
"Commander, the estimated time of contact is 197 seconds. The enemy has discovered us and is attacking us!"
"Leave it to the black-armored fleet. At the same time, get the Ares team to prepare to open up a path!"
"Yes, Commander!"
7AU...
5AU...
1AU...
As time passed, the fleet was only 1 AU away from the front of the army of the biological civilization.
Of course, during this period, the fleet was also heavily targeted by the army of the biological civilization. All sorts of creatures with long-range attack abilities attacked the fleet crazily.
However, with the black-armored fleet, such attacks did not cause much damage to the fleet. At most, the black-armored warships at the front used up a lot of the black cavity particles on their armor, causing their defense to constantly weaken.
Sophia had long since prepared for this situation. Whenever the density of particles in the black cavity armor of the front warships weakened to a certain extent, they would be replaced by other full-strength warships.
Therefore, even though they suffered many attacks, they did not lose a single warship.
However, now was the time. When they truly charged into the formation of the biological civilization's army, the real test would begin.
Looking at those massive bodies, Sophia even had a feeling that if the black-armored warships were to be punched by them …
Although they would not be destroyed, they might be sent flying …
Tens of millions of kilometers!
