In addition to these main and secondary guns, there are tens of thousands of fortress guns, all of which are capable of firing electromagnetic railguns filled with antimatter shells.

At the same time, the fortress is also equipped with up to 10 million piercing drones, which can engulf an entire fleet in an instant!

Inside this space fortress with a diameter of 80 kilometers, there is also a huge city that can accommodate 20 million people at the same time.

The city is equipped with all kinds of entertainment facilities, mainly so that the officers and men of the Imperial fleet can have a place to entertain and relax, and release their tense nerves.

Of course, this city is only accessible to ordinary citizens of the Empire, and clone soldiers have no chance to enter the city to rest.

Although this fortress is not the size of a stellar fortress, it contains technology that is far ahead of that of a stellar fortress.

A five-kilometer-diameter dimensional reactor that emits powerful energy by continuously reducing matter to drive the entire fortress forward, this kind of reactor spans an era compared to the stellar reactor of the star fortress!

At the same time, the weapons it carries that can destroy stars are far stronger than Star Fortresses in terms of range, cooldown, rate of fire, and accuracy.

Although it is like a grain of sand in the desert compared to the size of the Star Fortress, its combat power is not weaker than the Star Fortress, and even stronger than the Star Fortress.

The dimensional armor on its surface is far stronger than the armor made of heavy metal on the surface of the stellar fortress.

What's more, the Empire also equipped this flagship with two layers of letter crystal heavy armor.

The cost of this flagship is enough to top the entire White Dwarf-Star fleet! However, it will be the centerpiece of the Empire's conquest of a new river system, so it will be built at no cost.

Equipped with a material and energy transit station, the Empire's flagship fortress is capable of more than just combat.

The supercomputer carried inside it can connect all warships to the grid, greatly enhancing the combat efficiency and weapon accuracy of the entire fleet.

The Bastion also provides material transfer supplies to all ships, acting as a mobile repair shop, which can transfer repair materials and robots to damaged ships so that they can be repaired directly in battle.

When the Imperial fleet had all passed through the portal, the Imperial fleet reorganized its formation and lined up neatly in front of the portal, encircling the Imperial flagship Fortress in the middle.

At this time, the flagship of the advance fleet was guided to dock on the outer harbor of the Fortress.

The commander of the advance fleet, General Van and a group of officers, led by the guards, came from the battleship to the port.

There was already a hovercar waiting here in the port for a long time, and after everyone boarded the hovercar, the hovercar drove straight to the command center where Li Mingze was.

A few minutes later, General Van and the others arrived at the very core of the fortress, the highest command organ used by the Empire to direct all fleets fighting in this river system.

A semi-circular silver building is located in the very center of the city inside the fortress, and this silver shell is made of the same material as the outer armor of the fortress, and it is absolutely impossible to destroy its outer walls with ground units.

The hovercar came to a steady stop in front of the main entrance of the building, where dozens of guards in heavy power armor were already waiting in front of the heavily fanned alloy door.

When General Fan and the others got out of the car, several guards stepped forward and began to scan the whole body of several people with a scanner.

"Confirm that it is safe, the DNA and soul fluctuations are all compliant, there are no abnormalities, and it can be released!" The guard in charge of scanning spoke to the other guards who were holding railing rifles and pointing them at several people.

"Roger!" The guards put away what they said was rifles, but they were actually electromagnetic railguns filled with antimatter, and turned to the alloy door.

At this time, the alloy door with dimensional armor and letter crystal armor began to cut open to the sides under the action of the internal machinery, revealing the narrow passage inside.

Every meter in the passage stood an elite Imperial Marine clad in heavy power armor and armed with a shotgun with a beam blade.

When General Fan and the others walked over, these soldiers all aimed their shotguns at the ceiling, which was also a way of saluting.

"I really don't know what this kind of defense can defend against." General Fan complained silently.

Don't blame him, anyone who sees such an important facility with only such a small number of defense troops will rush to the empire and be a little arrogant and underestimate the enemy.

But if he knew the true identity of the guards, he wouldn't have said that.

The elite Marine Corps responsible for the defense of the facility was not selected from among ordinary people.

They were master Sith warriors selected from among the Sith warriors who now numbered as 10 million in the Empire!

After strengthening the bodies of these Sith warriors, they were sent to the Marine Corps for tactical training.

At the end of the day, they will be sent a set of heavy power armor with dimensional armor and letter crystal armor to serve as guards in important institutions throughout the empire.

These elite marines who are responsible for defending the command center of the fortress can easily use the power of the Sith to fly dozens of mecha chariots.

One can imagine how many landing troops the enemy would need to send to capture the command center guarded by these elite marines in order to capture alive the Imperial officers in the command center.

After passing through dozens of alloy doors and passing through this five-hundred-meter-long corridor, General Fan and the others finally came to the final alloy door.

Four guards stepped forward to help a few people push open the heavy alloy door, revealing the world behind the alloy door.

Behind the alloy door is a huge hemispherical hall several kilometers in diameter, and the walls around the hall are flickering with various images and messages.

And in the middle of the hall is a hologram of the spiral river system with a diameter of nearly 100 meters.

However, there is no data on this hologram that shows that the data that really matters can only be seen by people through the spirit linker according to their respective permissions.

And in this huge hall, neatly centered on the hologram, a circle of workbenches is placed in a radial shape, on which countless officers are busy.

At the same time, thousands of seats were suspended in the air, and on each seat sat an officer, who walked around the hall, and the entire command center was busy.

"Xiao Fan, your work has been very good during this time, and you have already laid down so many colonial stars of the Spiral Federation!" Li Mingze applauded and walked from the road between the workbenches to General Fan and the others.

"Long live Your Majesty! Long live the Empire! General Van and the other officers hurriedly gave a military salute and shouted loudly.
