More than ten days later, the last Imperial advance fleet arrived in the river system.

The fleet consisted of only 1,000 escort ships, and the remaining 9,000 ships were all transports with portal parts.

As soon as the fleet arrived, the Imperial advance fleet sent captured warships to assist.

The fleet followed the escort fleet directly to the star system where the Empire's forward base was located.

Nine thousand transports began to line up neatly in a circle and aligned their own cargo holds in the center of the circle.

Immediately afterward, the heavy armor of the transports' cargo compartments sliced open to the sides, revealing the portal parts that had been secured to the cargo holds.

At this time, hundreds of thousands of unmanned construction spacecraft flew out of the forward base, and these spaceships flew outside the cargo hold of these transport ships and stretched out their mechanical arms.

One by one, the robotic arms were attached to the shells of the parts inside the ship, and began to grab the portal parts from the transportship little by little.

Dozens of minutes later, 9,000 parts appeared in the universe, and the construction unmanned spacecraft began to converge towards the center, and the distance between these parts began to shrink, gradually becoming a circle shape.

These parts were docked together with the help of the construction unmanned ship, and finally became a whole, a huge circle suspended in the universe.

This circle is the Empire's upgraded portal, which is a hundred kilometers in diameter, enough to accommodate all the Empire's warships through the portal.

"The portal is built, and the debugging begins!" A staff report can be heard in the communication channel.

A large amount of silver liquid suddenly gushed out of the joints of the various parts of the portal, and the silver liquid merged with the parts after filling in the seams between them.

"Portal Integrity 100%"

"The 90,000 components that make up the portal are all functioning properly, and the energy is channeling through the internal network."

"The portal structure is 100% strong, and it can be used for teleportation missions!" The voices of the staff were heard again in the communication channel.

"Notify the Empire that the portal can be activated!" The Imperial Fleet Commander nodded and ordered to the communications officer beside him.

"Yes!" The Communications Officer sent the prepared message to the Imperial mainland.

Inside the Shenzhou in the river system next door, Li Mingze clapped his palms with satisfaction as he looked at the information sent back.

"Sky Wing, the portal can be opened, the advance team has cleared the safe area for the portal, and the portal is working normally." Li Mingze raised his head and said in a deep voice to Tianyi on the side.

In one of the star systems of the river system where the empire is located, a huge ring with a diameter of hundreds of kilometers is silently floating in the starry sky.

This ring is different from the rings built by the Empire in the spiral river system, and it is surrounded by eight large cylinders that extend outward.

Around this circular building are countless Imperial warships, ten fortresses hundreds of kilometers in diameter, and stellar fortresses that are quietly suspended not far away.

"Your Majesty has given the supreme order to activate the portal!" The staff in charge of the portal conveyed Li Mingze's orders to each other.

The ten responsible persons glanced at each other through the psychic network and pressed the start switch together.

"Sixty percent of the energy in the empire is being mobilized, all power plants and Dyson spheres and stellar energy extraction facilities in the empire are running at full power, and the energy is being channeled into the empire's energy network!"

"The energy peaks that the energy network is bearing are increasing, and the energy is being channeled into the portal!"

"Energy Channeling Progress 10%!"

"Energy Channeling Progress 32%!"

"Energy Channeling Progress 74%!"

"Energy channeling complete! All the energy is being injected into the portal's internal energy network! ”

At the same time, the lights on the streets of the colonies of the empire suddenly dimmed, and the brightness became only 10% of what it used to be.

All decorative lights in Imperial cities were extinguished, and civilian factories throughout the Empire stopped production and turned off their power after receiving the Imperial notice.

Now the entire empire can guarantee the energy supply of the road lights in the cities and the power supply in the hospitals.

In addition, the Imperial Academy of Sciences and various defense facilities of the Empire still have energy to use, and all other civilian facilities have entered energy-saving mode to save energy.

Sixty percent of the energy in the Imperial Energy Network poured into the area where the portal was located.

As more and more energy gathers, people in reality can even see that energy that should be invisible begins to appear in the air.

In the star system very close to the portal, people can even see flickering yellow light pouring down the wormhole passage at one end of the star system into another wormhole passage.

Because the propagation of energy is also the speed of light, the only way to quickly gather these energies from the entire empire to the star system where the portal is located is through the wormhole high-speed passage.

Now all the ships in the high-speed passage of the wormhole in the empire have long been emptied, and all the passages are forbidden to all spaceships to enter.

"The stability of the wormhole channel is 42%, which is still within the acceptable range!" The technician in charge of observing the wormhole passage breathed a sigh of relief, he was originally worried that such a high intensity of energy passing through the wormhole passage would cause the passage to burst, but now it seems that he is too worried.

Under the guidance of the Empire's energy transmission station, this energy does not seem to leak much energy to the outside world, and the wormhole passage remains stable.

The galaxy in which the portal is located is even more spectacular.

Tens of thousands of beams of energy flashed yellow like streamers from the exit of the high-speed passage of the wormhole built around this star system, and rushed directly towards the portal located in the middle of this star system.

This embodied energy has turned the entire galaxy into a giant filament hole, and tens of thousands of energy beams converge from the surrounding of the galaxy to the center of the galaxy like spider webs.

Immediately afterward, these energy beams poured into the eight cylindrical buildings that protruded from the portal, and the cylindrical buildings directly turned into a dazzling yellow.

The yellow light began to spread along the columns towards the portals.

The portal seemed to have been eroded, and the surface began to slowly cover with yellow lines.

"The energy absorption level of the portal has reached one hundred percent!"

"The energy has entered all the components through the energy network inside the portal, and the portal is opening!"

"Coordinates and locations start entering!"

"Coordinates and locations are entered! The channel is opening up! With the roar of the technicians, a white curtain of light appeared in the center of the portal's ring.

And at this time, this white light curtain turned blue.....
