With the closure of all the Empire's man-making facilities, the Empire's population growth came to a standstill.

Thankfully, 80 percent of the citizens of the Empire are the elite of the Empire.

The vast majority of them are scientists and engineers, and only 20 percent of them, or more than a trillion people, are citizens who have no value.

And the clones of the imperial folk have become extinct, and there has been a labor shortage in various service industries and families, and the clones who could provide various services have been destroyed, and now these positions are naturally vacant.

At this time, androids and robots began to flood the market, and almost every family had an android or robot servant.

What these citizens don't know is that the robots and androids they spend money on are actually all converted from military to civilian use, and these robots and androids can become elite warriors when they lift their weapons.

They are not only the eyes of the imperial family in the people, but also a weapon to maintain the rule of the empire, and in the future, any accident will have these robots and androids in front.

In less than a decade, peace had returned to the Empire, and the Empire had returned to normal.

The footage of the event that most of the population went dormant has faded, and the Empire's technological research and development is back on track.

The Imperial fleet, which had been resting in the harbor for hundreds of years, also began to regroup and head for a new river system.

The imperial calendar is 3,500 years, and if you put it on Earth, it is the thirty-sixth century.

The Empire has completed the unification of the surrounding river systems, and the entire galaxy group of 38,000 river systems has been completely controlled by the Empire.

By the time the expansion plan progressed, these new river systems that had joined the empire seemed to Li Mingze to be nothing more than numbers.

By the late stages, the Imperial fleet had grown large enough to attack hundreds of river systems simultaneously without running out of forces.

The Imperial advance fleet alone that could teleport directly had reached the point where it could capture a river system on the day of teleportation.

At this time, the empire became a powerful super civilization in the true sense of the word.

Now the only thing limiting the expansion of the empire is no longer resources and troops, but the population of the empire.

The current empire is barely able to sustain 300 million imperial citizens in a single river system.

It seems like a lot, but we need to know how many fifth-level habitable planets suitable for human habitation in a river system can be.

In other words, there are tens of thousands of Imperial citizens on each planet.

This is the size of a village in the previous empire!

But in the current empire, this is already the population of a medium-sized city, and even a smaller city has only a thousand people.

Land, resources, these once precious things are now of no value to the citizens of the Empire.

Each of them can be assigned to a few galaxies if they wish.

It can be said that the current empire has no interest in territory and resources, and the only thing that can make Li Mingze mention the nature is to counterattack back to the main universe.

Although the Empire's fleet is strong now, the amount of energy needed to bring it all back to the main universe is not a small amount.

However, Li Mingze had already prepared, and he had already saved 10 million Zeus III new warships.

With these 10 million Zeus-class warships, it is not too easy to defeat the Zerg in the main universe!

Of course, this was because Li Mingze didn't know what the main universe had become, otherwise he would never dare to think that his 10 million Zeus III warships would be able to counterattack back to the main universe.

He already had some ideas about how to return to the main universe.

Since it takes a lot of energy to maintain the space-time channel, then the empire must not be able to build the reactor on its own, after all, the energy required is too large.

And now, aren't there ready-made reactors floating in the various river systems, and the energy surging in those colorful stars is exactly what the empire needs.

Although these stars can only be said to be a kind of primitive reactor, they can't stand each other's volumes, and the energy they can provide is not low.

In addition, the empire's biological Dyson ball technology is very mature, and the resources consumed by a Dyson ball are not outrageous, and the only thing consumed is just nutrient solution.

If the speed of light propagation in this universe is infinite, then people standing outside the river system where the empire is located will look up at the starry sky and see that the river system occupied by the empire is darkening at a speed visible to the naked eye.

The reason why these river systems have darkened is because the Empire has "turned off the lights", and all the star systems that have no resources to use are used by the Empire as energy farms.

The stars in these systems will be covered by the Empire's Dyson sphere in just ten years, and at that point, the energy generated by this star will enter the Empire's energy network.

Li Mingze named the Dyson sphere construction project, which covers trillions of star systems: Energy Farm.

Once the Energy Farm project is complete, the amount of energy the Empire will be able to use to build the Space-Time Portal.

That's when the Imperial fleet counterattacks back to the main universe!

Taking advantage of the time when the Dyson sphere was built, Li Mingze began to study the virtual world that sealed ten trillion citizens of the empire.

It was a shame that these ten trillion citizens of the empire were wasted like this, and he had to find a way to put them to good use.

Thinking that the empire's current landing force was still composed of old-fashioned clones, Li Mingze had an idea.

These clones are a bit rigid in some cases due to their lack of emotion, and they can't have feelings, and the citizens of the empire who enter the virtual world do.

It didn't take long for a special game world to suddenly appear in the virtual world.

Anyone can participate in this game world, become a clone soldier of the Empire, and participate in the battle between the Empire and various civilizations.

Since the virtual world has been isolated from the outside world for hundreds of years, the empire has changed so much in these hundreds of years that these people don't even know that the game world they enter is actually reality.

Thankfully, the clones that were destroyed had a trillion people left free, allowing these Imperial citizens to reappear in the world as clones.

They will receive new training in the Barracks of the Empire, and these citizens of the Empire are not aware of it, and in their eyes it is just a game, they have no idea that the game world is actually reality.

The Empire is training these soldiers for the counterattack on the main universe, and anyway, it is still a long time before the space passage is opened, so it is completely possible for these soldiers to fight against each other to hone their combat skills.
