The Phantom-class battlecruiser continuously fired its main guns.
Soon, any space defense platform or weapon station that dared to show its head would be directly penetrated by the void shield and exploded in space.
Countless space debris was produced after this battle.
The outer weapon platforms were almost destroyed, and the task force strike group continued to advance, soon bringing the main body of the Sky Fortress within the attack range.
There are obvious differences between the fleet and the main body of the Sky Fortress in terms of attack and defense.
The Sky Fortress is larger, with a disc-shaped shape and a diameter of over 100 kilometers. It has thick armor. Even if the void shield is broken, it can rely on the armor to continue to hold on for a long time.
On the Sky Fortress, there are more than two hundred fourth-generation arc guns, which are their most powerful means of attack.
This concentrated arc main gun is even larger than the one on a battleship and has a longer range.
However, even if the range is slightly longer, it does not change the identity of their fourth-generation main guns, and the maximum range is only 500,000 to 600,000 kilometers.
But compared with the main gun of the Phantom-class battlecruiser's fifth-generation Starburst Cannon, it is on a different level.
The range of the Starburst Light Cannon reaches 900,000 kilometers, and it can directly attack the ground outside the range of the Sky Fortress.
The Sky Fortress is too huge, and its location is calculated by gravity, making it difficult to move.
The enemy's warships can still rely on their own maneuverability to approach the Phantom-class battlecruiser, but the Sky Fortress has no choice but to take it head-on.
Although the warships look huge, they are made of advanced materials and structural designs.
The fourth-generation warships all have stealth capabilities, and the signals exposed by radar and various electromagnetic search systems are very small.
The fleets of both sides fought at a distance of hundreds of thousands of kilometers.
It is impossible to fight at such a long distance by relying on the naked eye.
If the sighting system cannot accurately lock onto the warship, then what is the use of having strong firepower strike capability?
You can't just get to close range and then open fire.
Therefore, even the main guns of battleships and cruisers may miss, because the signals of locked enemy ships may not be accurate.
It doesn't mean that firing means hitting the target. You have to lock on first before you can fire and hit the target.
But the Sky Fortress is different. It is too big, and no stealth technology is useful, let alone using various advanced technologies to lock it.
From a distance, you can lock onto this big guy with your naked eyes and there is no chance of missing it.
The Phantom-class battlecruiser in the task force strike group, the Dreadnought flagship, began charging its main guns.
Terrifying energy fluctuations began to converge in front of the battleship's main gun.
Inside the flagship, Li Xin ordered, "Open fire!"
"Let the people of the Sky Fortress have a taste of the fifth-generation main gun and the Dreadnought main gun!"
"Yes! Grand Marshal!"
Orders were passed down step by step, and soon, large warships began to fire at the same time.
“Squeaky, squeaky!!!”
Dazzling beams of light were emitted from the front of the Phantom-class battlecruiser.
Six hundred dazzling beams of light pierced the dark night sky like sharp arrows.
Then the dreadnought main guns of the nine dreadnought flagships began to attack.
“Boom boom boom!”
Nine red beams of light almost tore through the barrier of the real universe and directly hit the void shield of the Sky Fortress.
“Boom!!”
Inside the Sky Bastion, the sound of the Void Shield being hit was heard almost instantly.
Six hundred fifth-generation main guns and nine fearless main guns attacked.
This made the Void Shield withstand countless energy attacks.
A massive amount of attack energy was transferred into the subspace, clearing out all the unlucky demons around.
Even an A-rank demon wouldn't want to endure an attack of this magnitude.
The violent roar made by the Void Shield when transferring the attack energy even made the entire Sky Fortress tremble slightly.
Many technical officers and psychics responsible for maintaining the void shield watched the energy consumption and the decline in the void shield's defense value.
His expression couldn't stop changing.
The strength of the Sky Fortress's defense can be seen from its size.
When this Sky Fortress was tested in the past, ordinary attacks would not even cause any ripples in its void shield.
The huge amount of energy can withstand terrifying attacks without any change.
But this time, the Galaxy Defense Group's attack directly caused the fortress's void shield energy to drop rapidly.
The officer in charge quickly passed the data up the chain of command and finally handed it to the fortress's highest commander.
The supreme commander looked at this string of data and couldn't help but take a deep breath. He said, "The enemy's main gun, what kind of main gun is this? How can it shoot so far and with such great power!?"
The Chief of Staff speculated, "Maybe it's the Galaxy Defense Group's new technology?"
The Supreme Commander said in astonishment, "From what I've seen from intelligence, the Galaxy Defense Group is a garrison state. Do they have such scientific research capabilities?"
Then he quickly shook his head and said, "First, immediately convey the enemy's combat effectiveness and your speculation about this main gun to headquarters and to President Duncan!"
"Yes, sir!"
A staff officer behind him immediately took action.
The Supreme Commander looked at the data analysis sent by the Void Shield Defense Department and couldn't help but sigh at the end.
In the face of such a terrifying attack, even a void shield like the Sky Bastion can only hold out for thirteen or fourteen days at most.
Once the void shield is overloaded, you should consider using armor to withstand enemy attacks.
The Supreme Commander asked, "Everyone, what should we do?"
"The main space combat group closest to us will take almost a year to arrive."
"And the fact that we were able to hold off the Galaxy Defense Group's fleet for another month was beyond our expectations."
"What should we do? Should we live and die with the Sky Fortress, or..."
The commander didn't explain it clearly, but everyone knew what he meant.
A soldier tentatively asked, "If we successfully delay for a month, will it be able to create any beneficial responses for the group and the surrounding industrial world?"
"Yes, but not much," one staff officer replied.
"In the industrial world, because of our containment, perhaps some high-level officials can escape, or industrial equipment can be destroyed."
"But this is obviously impossible. Even if it's an order from the group headquarters, no one will carry out the order to destroy industrial equipment once it lands on a planet."
"A group is a group, a planet is a planet..."
"We persevered and remained loyal, but it was difficult to achieve any positive impact or change for the group in a short period of time."
