"Enemy attack!"

"Enemy attack!"

The reconnaissance officer shouted at the top of his lungs, and his voice instantly echoed throughout the command hall.

The officers who were originally in the process of changing shifts were thrown into chaos when they heard the alarm.

The news quickly reached the commander of the Sky Fortress. A series of reminders made him stand up without even pulling up his pants.

“Ouch!”

The commander howled in pain, but quickly pulled up his pants and rushed out of the office.

He asked loudly, "What's going on?"

"What on earth just happened!"

"Where did the alarm come from!?"

An adjutant rushed over and reported, "Sir, this is bad. We've detected a large-scale, unknown psychic jump signal!"

"They're heading straight for our Sky Fortress!"

"According to the data, it's estimated to be at least five to six thousand warships! And they're moving very fast."

The commander asked in panic, "Where did these five or six thousand warships come from?!"

"Didn't the prediction say that it would take at least two years for the enemy warships to arrive?"

The five or six thousand warships about to arrive at the Sky Fortress made the commander guess that perhaps this was just a vanguard of the enemy and the main force was not far behind.

"How come we're only now realizing that the Subspace Exploration Department is just for show?!"

The commander took the intelligence information with shaking hands.

As he reviewed the intelligence, he issued a series of orders: "Immediately order all troops to stop resting and return to their respective posts!"

"Order the surrounding industrial worlds to quickly transport the recently produced warships to the defense line!"

Several adjutants and staff officers followed the commander, listening to his orders and then carrying them out.

The commander said: "Order the fortress to activate the highest level of alert!"

"At the same time, send a request for assistance to the group headquarters and report the situation here as soon as possible so that they can make emergency plans early."

"Also, fully monitor the surrounding star fields. I want to know when the enemy's follow-up troops will arrive!"

A series of orders were issued, and the entire Sky Fortress defense line was slowly waking up.

There are small transport ships, high-speed carrier-based aircraft, etc. flying everywhere.

They were transporting officers and soldiers who had originally returned to the fortress or even to the life planet below to rest back to their own bases.

The entire defense line is in a state of drastic change.

On the other side, the Galaxy Defense Group's Starry Sky Task Force strike group has already arrived inside the galaxy.

In the flagship, Li Xin sat on the mechanical throne, looking at the shadow of the Sky Fortress in the real universe outside the subspace.

He said, "It seems we have arrived at the right time!"

"Pass my orders!"

"Jump into this system!"

"Yes! Grand Marshal!"

Orders were issued step by step, and the psychic jump engines of the nine leading dreadnought flagships opened the barrier of the real universe.

Nearly six thousand warships, led by psychic tractor beams, followed the dreadnought flagship and arrived at this line of defense.

In space.

The barrier of the real universe ripples like water waves, emitting flashes of subspace.

In a vacuum environment, sound cannot be transmitted, but inside the Sky Fortress, the defense commander stared in amazement at the scene transmitted back from the front line.

The things in my hands fell unconsciously.

Even in a vacuum and silent environment, just looking at the battleship can transmit sound.

One after another, the warships, led by the fearless flagship, returned to the real universe.

The commander of the Sky Bastion's voice grew hoarse as he asked, "Dreadnought flagship?"

"Nine!?"

"Where did these nine dreadnought flagships come from?"

"Nine dreadnought flagships, coming to attack my unmanned Fortress defenses?!"

The commander was in tears and could not believe what he saw.

But the huge size of the ship clearly showed that it was a terrifying and fearless flagship.

One of the absolute rulers of the human space fleet.

In the command center, everyone who knew this battleship felt very upset at this moment.

The commander's voice was dry: "Quick! Report to headquarters!"

"I'm afraid we can't hold out much longer!"

"Yes, sir!"

On the other side, the Galaxy Defense Group's task force strike group had completed its repairs, and the ships began to slowly advance.

Li Xin looked at the weapon platforms scattered along the front line of defense scanned by the Dreadnought flagship and said, "We don't have much time to waste. Order the small and medium-sized ships and escort ships to establish a defense line immediately!"

"The Phantom-class battlecruiser, the Dreadnought flagship, will serve as the main force in this battle!"

"Once we reach firing range, open fire! Let them see our firepower!"

"Yes! Grand Marshal!"

The fleet pressed forward.

Escort ships, destroyers, and frigates formed four consecutive lines of defense.

After entering the shooting range, the Phantom-class battlecruiser opened fire directly, and a series of star-splitting light cannons shot out.

"boom!!"

The void shield on a weapon platform was under attack from the Starry Sky Light-Splitting Cannon, and the void shield was consumed extremely quickly.

The soldiers and officers inside the weapon platform were extremely panicked at this point.

The next moment, the beam of light destroyed the void shield, and the void shield generator overloaded with black smoke.

The beam of light tore through the outer armor, and the sound reached the ears of the soldiers and officers inside. They could only close their eyes and pray.

But prayers were useless at this time. The armor was torn apart, and the soldiers and officers were annihilated without even a scream.

One space weapon station after another was precisely eliminated, destroying the enemy's outer defense line.

Inside the command center, the supreme commander had regained his sanity at this time, and he quickly issued orders one after another.

Soon, hidden weapon stations inside galaxies, on large planets, in asteroid belts, and even in meteorite belts, began to open fire.

Dense space missiles and space torpedoes shot out and shot towards the fleet of the Galaxy Defense Group.

At this time, the small and medium-sized ships on the periphery, and even the Guardian-class escort ships, came into play.

They intercepted these long-range weapons to prevent them from interfering with the firing attacks of the Phantom-class battlecruisers.

The task force strike group advanced very quickly. Any weapon station that dared to open fire or expose its position would soon be hit by the long-range attack of the Starry Sky Light-Splitting Cannon.

Basically, no weapon station can survive the attack of this terrifying fifth-generation main gun.

Once locked, it is only a matter of time before it is destroyed.

When the casualty figures were reported to the defense commander, he hardly dared to look at them.

If he looked closely, he himself would probably burst into tears, the number of casualties was simply too great.

The Galaxy Defense Group's task force continued to advance, and the defense commander roared, "Move out the carrier-based aircraft!"

"We can't just sit there and wait for death!"
