In a void in the direction of the Imperial Dragonpony River System to the Gross River System, this was originally a remote area of the Dragonhorse River System, sparsely populated, and there were no Imperial people living within a few hundred light-years of the surrounding area.

However, in the last 100,000 years, this place has been very lively, the Imperial military has enclosed the surrounding area of thousands of light years and listed it as a military forbidden area, and the Imperial Time and Space Administration has hidden this area from the Imperial Star Map, and ordinary spaceships cannot fly here at all.

A large number of spaceships from the Imperial Academy of Space-Time Science arrived here, constantly busy in the entire void, exploring the surrounding void, mining planets, asteroids, meteorites, etc., starry systems around each other, huge space factories continue to operate, and a steady stream of smelting something.

In an empty void, space ports and space cities are distributed very regularly, presenting a spherical shape, which seems to surround an area in the middle.

The entire void was very busy, with the rise and fall of spaceships, space warships, and the endless stream of small spaceships, the brightly lit space city and space port, everything seemed very busy.

In the center of this area, it is even busier, spaceships are constantly transporting something here, and there are space ports in the void, and the universe is very moored in the space ports, the hatches are wide open, and the mechanical arm carries out the large parts in the warehouse.

These parts are very large, 10 kilometers long, 2 kilometers wide, and 1 kilometer high, and often a spaceship can only transport one or two of these large parts, and these spaceships are still specially modified spaceships, spaceships specially designed to transport these large parts.

The parts were unloaded by the robotic arm, and the spacecraft took off to make room for space, as there were more spacecraft waiting to be unloaded behind.

In the space port, the robotic arm transports the parts to the assembly place, and although all the parts are large, they are all carefully designed and calculated, like bricks, and are slowly assembled onto a giant object.

At this time, I could not see the whole picture of this object, only a huge pillar, which was now millions of kilometers high, standing quietly in the void like an optimus pillar, and compared to this long stick, the space port leaning on this pillar was very small.

As far as the eye can see, this void is very wide, as large as a solar system, and it is very busy everywhere, and I don't know what the scientists of the empire are building, and there are actually 4 huge pillars in the void that are being built at the same time.

"It's too slow, it's been 100,000 years, we haven't even finished 10% yet, and it may take us millions of years to finish."

In a space port, Long Shaofei looked at the virtual image, very dissatisfied with the current progress, as a new leader in the field of space science in the empire, he is now the person in charge of the major project here.

"Take your time, don't worry, we are laying the foundation in the first 100,000 years, and the progress will be faster and faster, this space-time gate is not so easy to build, all the materials are degenerate materials, even our empire is very rich now, but the empire's finances have suddenly become tense over the years."

"If we concentrate more strength and financial resources to build the Gate of Time and Space, our Imperial Prime Minister may have to scratch his hair, these are all degenerate materials, and the space battleship is only used on the surface, but our side is used as a whole piece, a whole piece, and we don't know how many galaxies need to be hollowed out to build."

Next to Long Shaofei, Yu An seemed very patient, he knew very well how expensive the huge project in front of him was, it was simply to use money to pile up, slowly push it up, and the most important thing was that it would take time.

"I also know, it's just that if the theory of space-time teleportation is not experimented, it will always be a theory, and I can't wait for it for a long time."

Long Shaofei smiled bitterly and shook his head.

Long Shaofei took the lead in realizing the mystery of space teleportation, over the years, imperial scientists have also made rapid progress in this field, but if you want to develop further, it is absolutely indispensable to practice, everything is the same, theory must be combined with practice to be able to truly develop.

"Take your time, don't be in a hurry."

Yu An smiled and looked into the void, the four huge pillars were still working day and night, and the massive spaceships were constantly transporting large parts, these large parts were insignificant compared to these four huge pillars, just like bricks and the Great Wall.

Time is slowly passing, 4 huge pillars have been slowly turning into the void, after 300,000 years, the 4 pillars slowly formed a rectangular frame, somewhat similar to a window or door-like structure, very perfect with each other, without a trace of mistakes connected together.

By this time, it was already possible to see this huge 'door frame' in space, which was more than 100 million kilometers long, as long as 1 astronomical unit, and 50 million kilometers wide, like a huge door lying across the void of the universe.

In order to build this huge space-time gate, the empire doesn't know how many galaxies have been hollowed out, and the planets, asteroids, meteorites, etc. in the galaxy have been hollowed out, and all the materials are used to create degenerate materials, and this huge space-time gate is not solid, if it is all solid, it is estimated that a large part of the starry sky of the entire Longju River system will be hollowed out.

The door frame composed of the huge space-time gate is depicted with complex lines, and the spaceships are testing the entire huge project, such a huge project, if there is a trace of unqualified, it means that the hard work of countless people for hundreds of thousands of years has been lost in vain.

On this huge gate of time and space, there are 9 huge holes, each of which has a diameter of more than 5 million kilometers, and all the carved lines seem to be carved around these 9 huge holes.

The huge space-time gate, the space-time gate made of degenerate materials, its mass is very huge, and in its vicinity, the space has been distorted and folded, and the faint space seems to be unable to withstand such a heavy space-time gate.

"It's finally done!"

Long Shaofei looked at the huge space-time gate standing quietly in the void, and let out a long sigh, just to build a space-time gate, the empire has concentrated a large part of its strength, and it still took 400,000 years, and the wealth consumed can no longer be measured by numbers.

"Now it's time to install the energy."

Thinking of this, Long Shaofei couldn't help but get excited again, the energy consumed by the Gate of Time and Space was very huge, and the traditional energy output could no longer satisfy its huge appetite, so the scientists of the empire thought of the stellar array, and directly picked the stars and used them as the core energy source.

In the void not far away, a team was using optical and magnetic traction technology and space translation technology to rapidly fly a star with a mass of 1.5 times the mass of the Sun in the direction of the space-time gate.

The team had already received the task 400,000 years ago, to find a suitable star in the nearby void to use as a source of energy for the space-time gate as the core, finding the right star is obviously a very simple matter, the most difficult key is to transport the star to the location of the space-time gate.

The mass of the stars is very large, and conventional means cannot move the stars at all, and moving the stars can easily cause gravitational chaos in the void of the universe, and may cause chaos in the void stars, so moving the stars is not an easy task.

Fortunately, the technology of the empire has developed to the present, although it is somewhat difficult to move stars, but it is not impossible, among which the optical and magnetic traction technology and space translation technology are combined, and moving stars can also be done, the so-called space translation technology principle here is actually very simple, the space is regarded as a plane, and when an object on the plane needs to be moved, it will exert influence in the corresponding direction, and a slope will be formed in this area, and the object above will naturally be moved.

Rely on two technologies to move stars, but this speed is certainly not much faster, 400,000 years have passed, and there is still some distance from the area where the space-time portal is located.

There were a total of nine teams like this, and each team was already dragging a huge star in the direction of the space-time gate.

These 9 stars are all carefully selected, with a mass about 1.5 times the mass of the Sun, and most of them have a lifespan of between 4 billion and 6 billion years, with similar mass, size, age, and stability.

Time is quietly draining away, the void where the gate of time and space is located becomes brighter, and within the small void range around, the 9 stars carried from afar are constantly emitting endless light, illuminating this side of the void, as if entering the kingdom of God dominated by light, and the light is one after another.

"Install the star!"

All the conditions were ripe, and Long Shaofei had already been eager to conduct experiments and began to order the installation of energy power for the space-time gate.

A team slowly dragged a star towards the huge space-time gate, and the hole reserved on the space-time gate was used to install the energy river star, a hole with a diameter of 5 million kilometers, it was more than enough to fit a star.

PS: Long waiting!
