The stars, but they become the gray wind

"But... the construction of a Time Bridge would take at least hundreds of years, wouldn't it?... And it only takes you about a year at most to complete the construction of all the facilities required for faster-than-light travel, including anchoring wormholes and artificial stargates, in the 5000-plus colonized star systems within your current territory. Isn't this window of a hundred years a bit too long?"

"No...it doesn't take hundreds of years to build a closed time-curve computer. Based on the technology you provided, we've developed a more time-efficient and cost-effective method for building a closed time-curve computer."

"Compared to wormhole time bridges connecting the past and the future, which take hundreds of years to complete in a subjective time reference frame, our solution can shorten the entire construction period to just a few years."

"What plan? How can it be so fast?" Kalisi asked Lina in surprise.

In the galaxy where the A001 neutron star flywheel power generation facility is located, more than hundreds of spaceships are eagerly waiting for the engineering ships and colony ships to arrive here from the mother galaxy.

"I heard that the high-dimensional space jump engine... is silent even when it is leaving the jump?" In one of the spaceships, a cat-eared girl with long black hair asked her companion.

"That's right... I have carefully studied the detailed information and technical parameters of the high-dimensional space jump engine sent from the mother galaxy. The high-dimensional bubble enveloping the spacecraft will not produce any visible impact or signs in the process of falling back into the three-dimensional universe. It will appear out of thin air at the destination area, just like a shadow passing across the ground." The cat-eared girl's companion, the young female elf with pointed ears, replied.

"Come to think of it... they're almost here, right?" Another elf woman who looked more mature checked the time.

"If I calculated correctly, there are about 10 seconds left. Oh, it's 9 seconds now, 8, 7, 6..."

The elf girl accurately counted down the stopwatch in her hand.

"5, 4, 3, 2, 1! Arrived!!" Following the elf girl's slightly excited voice, hundreds of giant colony ships and engineering ships appeared out of thin air about 2000 kilometers in front of the fleet responsible for receiving them, following the collapse of the total-reflection warp space bubble. Even when the high-dimensional warp bubble returned to the three-dimensional universe and collapsed, all the ships responsible for receiving them located 2000 kilometers away did not detect any observable space and gravitational wave disturbances. Hundreds of superluminal ships equipped with high-dimensional space jump engines appeared out of thin air in front of them.

"Wow... there really is no movement at all!" exclaimed the black-haired cat-eared loli.

"Just like you said... a shadow passes across the ground... whether entering or leaving a warp, it leaves no trace."

…………

On the other side, after entering the galaxy where the A001 neutron star flywheel power generation facility is located, several unmanned automatic engineering ships quickly separated from the main fleet and rushed towards several large-mass asteroids with a diameter of 100 to 300 kilometers in the galaxy at a speed close to 0.5c of light. After approaching the asteroid, several engineering ships launched several nano-mechanical airborne capsules towards the surface of the asteroid. The airborne capsules landed on the surface of the asteroid, and the nano-machines stored inside rushed out and began to devour the entire asteroid. The huge amount of matter contained in these asteroids with a diameter of more than hundreds of kilometers will become the raw materials for nano-machines to build artificial star gates. Within a few days, these originally huge asteroids will be completely devoured, and the nano-machines will begin to build artificial star gates on the spot using the materials obtained from the asteroids.

…………

Hundreds of engineering and colony ships passed by an artificial dwarf planet that was cutting the magnetic flux lines of a neutron star. The surface of this artificial dwarf planet, made of color-nuclear-force fully reflective material, was reflecting the bright light of the neutron star. As a high-speed magnetar, the invisible magnetic flux lines generated by the neutron star's powerful magnetic field cut through the surface of this artificial dwarf planet, which rotates in the opposite direction of the neutron star's own rotation. As a huge gravitational potential energy battery, the 60 artificial celestial bodies including this artificial dwarf planet are all completely unmanned automatic facilities. For nearly 100,000 years, they have been collecting and storing the enormous energy generated by the neutron star, and transmitting the energy to space habitats throughout the galaxy in the form of gravitational waves and high-energy lasers in the gamma-ray band.

In fact, the energy provided by the Dyson Cloud built around the stars in the more than 5000 star systems controlled by the Sky Star civilization only accounts for a small part of the total power output of the entire civilization. The hundreds of neutron star generators, including the A001 neutron star flywheel power generation facility, are the bulk of the energy output of the entire civilization.

Each neutron star generator provides energy equivalent to the total energy of at least 400 to 800 stars.

Therefore, for the Sky Star Civilization, the Dyson Cloud in a considerable number of star systems is more like a face-saving project that only provides auxiliary properties, and the neutron star generator is the real power generation force.

Except for a few galaxies whose stars are blue giants or red supergiants, the total energy power generated by the Dyson cloud project in these few star systems with special stellar properties can exceed the power of some neutron star energy collection coils. However, since stars such as blue giants are also extremely rare among the more than 5000 star systems controlled by the Sky Star civilization, the largest proportion of the energy output power of the Sky Star civilization is still these hundreds of neutron star flywheel power plants.

And around the neutron star generator with the oldest history and longest operation since this Sky Star civilization became an interstellar civilization, a fleet of superluminal engineering ships from the mother galaxy is planning to carry out a new astronomical-scale megastructure project.

Six star arm energy-gathering wells were ejected from the cargo hold of the engineering ship by the gravitational acceleration field of the tractor beam and flew towards the low orbit of the neutron star. Four energy-gathering wells were deployed at the equator of the neutron star, arranged in an equiangular quadrilateral configuration at a distance of less than 1500 kilometers from the surface of the neutron star. The other two energy-gathering well facilities flew towards the north and south poles of the neutron star. With all six energy-gathering well facilities in place, according to the initial setting program, a tractor beam of a specific frequency was shot towards the neutron star below. This tractor beam would rely on its own strong gravity to create a gap on the surface of the neutron star that goes straight to the core, and extract the strange quark cluster matter in the core of the neutron star and store it in the special storage container of the energy-gathering well facility equipped with a stasis field.

As for the transportation of strange quark cluster materials from the core of neutron stars collected by the energy-gathering well facilities, the Tree of Life and the Sky Star civilization have also adopted an unusual means of transportation. Several small anchored wormholes will be placed near the energy-gathering well facilities, and the exits of these micro-wormholes will be set in spacecraft equipped with high-dimensional space jump engines. The spacecraft can use the micro-wormhole exits it carries at any time to export a steady stream of strange quark cluster materials to replenish the consumption of the high-dimensional space jump engine during operation, thereby realizing that a spacecraft truly does not need to go to specific maintenance or refueling facilities to replenish special fuel such as strange quark clusters.

Chapter 149: Civil Engineering and Greyhounds, the Building Blocks for the Milky Way? (5000 words)

At the edge of the A001 star system, several massive asteroids with diameters exceeding hundreds of kilometers are rushing towards the same target in the dark space at an orbit and speed that is completely impossible to occur under natural conditions.

At this time, the materials and minerals inside these asteroids have been completely hollowed out, and only the appearance still maintains the original appearance of normal asteroids. They have become carriers of nanomachines. Under the action of inertia-free propulsion devices, several asteroids have become zero-inertia missiles, flying at a speed close to 90% of the speed of light towards the edge of the galaxy, away from the influence of the neutron star's gravitational well.

.........

Behind several asteroids, in a hangar of a research vessel with a long axis of more than ten kilometers, a black-haired cat-eared girl watched the real-time image of the asteroid playing on the holographic projection in front of her.

"It's almost approaching the speed of light..."

"Based on this speed... we'll reach the designated location in half an hour at most, right?" The black-haired cat-eared girl zoomed out. On the extension line of the asteroid's current direction of travel, there was an area marked with a blue triangle. That was the destination of several asteroids that had become carriers of von Neumann's self-replicating machines. They would start the construction of large-scale artificial star gates and anchored wormholes there.

"But considering the bumpy and dirt-covered surfaces of these asteroids, I always feel like something is a little weird," said a pointy-eared elf girl companion to the black-haired cat girl.

"I admit that these asteroids are not very good-looking, but in terms of size and quality, they are the most suitable raw materials for building a stargate."

"Other asteroids that are smaller in size and mass, or have lower levels of heavy elements, can be used, right? It's just that the number of asteroids that need to be deployed with nanomachines will increase slightly..."

"That's why practicality and efficiency come first. Although these asteroids aren't very round and are rather ugly, their heavy element content makes them the top choice as raw materials..."

"Besides, these asteroids are just raw materials. After the stargate is formed, the asteroids themselves will be almost completely consumed. The worst that can happen is that we can just turn a blind eye..."

"That's not what I'm concerned about... I'm concerned about converting an asteroid into a lightspeed spacecraft capable of inertia-free travel... It always feels a bit... what's the word?"

"Greenskin?"

"Yes, that 'greenskin' thing. I always feel like these asteroids traveling at near-light speed have a certain aura... I feel like they're full of that flavor I'm just imagining." The black-haired, cat-eared girl tapped her crown lightly with one hand.

.........

Half an hour later, all the asteroids had arrived at the expected positions. In this area far away from the neutron star's gravitational well, several asteroids with huge volume and mass, which originally contained a large amount of heavy elements, were arranged in parallel in space in the form of an equilateral polygon. As the last asteroid perfectly entered the correct position of this polygon, silver dust began to appear on the surfaces of all the asteroids. Along with the silver dust, there were also blue-green threads and fibrous substances like tree roots that emerged from the surface of the asteroid. As the silver dust swept across the entire outer surface of the asteroid, the huge asteroid began to gradually decompose, and the remaining mass of the asteroid's outer surface was converted into part of itself by the silver dust. The threads and fibrous substances that broke out from the surface of the asteroid were also growing continuously, extending themselves wantonly in the vacuum, and each bundle of growing fibers spread towards the other asteroids that made up this polygon.

After all the asteroids were completely decomposed by the silver dust and fibrous material with blue-green lines on the surface, the fibrous material growing from the surfaces of different asteroids also stretched to sufficient lengths in the vacuum and then joined together, completely merging into one at the joints.

These mainly silver fibrous substances formed a huge ring in space with a diameter of more than 1000 kilometers. This is the basic structure of the artificial star gate. After the ring-shaped basic structure was formed, the blue-green lines on the surface of the star gate became brighter, and the silvery-white fibrous substance that constitutes the star gate itself also began to quietly change its physical properties. The originally flexible fibrous substance gradually became very hard, and eventually turned into a true rigid body. The microscopic elementary particle structure of the star gate's ring-shaped main frame was also quietly changing, gradually turning into the unique mirror surface of the color core material that fully reflects electromagnetic waves of all frequency bands.

Now, the basic structure of this star gate has become truly indestructible. The main frame is made of a color material with full reflective characteristics, which makes this star gate strong enough to withstand the damage caused by a supernova explosion. Unless a black hole directly hits the star gate itself, there is almost nothing that can cause damage to the star gate under natural conditions.

.........

"It's quite fast..." The black-haired cat-eared girl glanced at the time on the screen in front of her.

"Hmm... from the time all the asteroids were put into position, completely broken down, and the entire stargate was fully formed, it took less than four hours. That's pretty good."

"Really? I think it's a bit slow..." The elf girl who was eating popcorn and watching the whole process of the star gate construction on the screen stopped in mid-air with her hand holding the popcorn.

"It's 1500 kilometers in diameter. In the past, when we built a structure this large, it would only take two hours at most, right?"

"Come on, this is a Stargate... It's not some simple space station that can be operated with just an automated life support system, an ecological circulation system, a reactor, an energy system, and a central control computer, and can be fixed in place without any need for movement."

"We're going to use this thing to create a wormhole that can span vast distances between star systems in an instant. It's understandable that the construction period and time are twice as long as a space structure of a similar scale."

"That being said... I still feel like it's way too inefficient to build a space structure that's only a little over 1000 kilometers long, taking nearly five hours."

"It won't take that long... Because the A001 galaxy is the largest, most complete, and longest-running neutron star power plant in the entire Sky Star Civilization, and as one of the most important energy infrastructures among our 5000-plus galaxies, it will have a significant demand for traffic. Therefore, the stargate built here will be larger, naturally taking longer to build and requiring more raw materials."

"Speaking of which... the information we obtained seems to mention technology for building small stargates anywhere and at any time. That should take much less time to build, right?"

"Yes, there are... However, the amount of traffic that a small stargate can accommodate at a time is relatively limited. However, the advantage is that it can be dismantled and rebuilt at any time."

"The Ansible Stargate—a small-scale artificial stargate. While small, it possesses all the necessary functions. This stargate has a short construction cycle, and its compact size allows it to be mass-produced and directly towed to the desired location by a tugboat carrying a tractor beam. It can then be activated on-site to form a stable wormhole passage."

"If we eliminate the tugboat's time to tow the Stargate to its proper location, the entire Stargate deployment and activation process will take no more than 15 minutes. It's incredibly convenient, fast, and hassle-free in every sense of the word."

"Of course, it's not without its drawbacks. Its small size means the wormhole has a smaller flow rate. Compared to the stargate in our galaxy, which has a diameter of 1500 kilometers, comparable to the diameter of some dwarf planets, the Ansible Stargate, as a portable, small stargate, is only 14 kilometers in diameter and can't accommodate too many oversized spacecraft at once."

"For example, the famous colony ship Salem has a long axis of over 26 kilometers. While it can barely pass through the Ansible Gate to create a wormhole, a pair of Ansible Gates can only accommodate one ship of Salem's size at a time. Otherwise, the entire wormhole will collapse due to the sheer mass and volume of matter passing through it."

"Only one ship at a time? That's certainly not enough traffic... Speaking of which... what's the traffic limit right now?"

"It's pretty big anyway... You could just send that incredibly massive neutron star in the center of our galaxy, with a diameter of 20 kilometers, straight through the wormhole in the center of the stargate."

"Or perhaps it would be no problem to allow several thousand Titan-class ships of the same level as the Salem to pass through at once."

"That aside... the Stargate is about to officially open the wormhole connecting to the mother star system. This is a historic scene."

………Enterprise O Wu private 877 Jun Yang…

At the edge of the galaxy, in the dark space at the center of the ring-shaped structure of the stargate, a large number of high-energy particles rushed to the center of the ring-shaped stargate with a burst of invisible gravitational wave disturbances. A high-energy neutrino stream shot out from the space void created at the center of the artificial stargate at a speed close to the speed of light.

Just as the universe was originally born from a point where there was nothing, the wormhole event horizon, like the surface of clean water, instantly filled the entire circular inner side of the star gate from the central area of ​​the star gate. As the neutrino jet ejected from it gradually disappeared, the bright wormhole interface like the shimmering water surface began to ripple like the surface of a lake blown by a breeze.

.........

[Confirmed that the wormhole interface has been formed... Sending information to the wormhole...]

A high-energy neutrino beam close to the speed of light was sent from the communication array on the spacecraft closest to the wormhole and sent into the wormhole. About 30 seconds later, the spacecraft, which was only a few meters away from the stargate,

15 light seconds later, the unmanned spacecraft received neutrino communication from the other side of the wormhole.

[Confirming the communication content... Confirmed to be a neutrino communication sent from the other side of the mother galaxy...]

As the artificial intelligence system on the spacecraft confirmed the source of the information, all the members on the spacecraft waiting on both sides of the wormhole burst into cheers.

This is the first time in the history of the entire Sky Star civilization that inter-galactic communication has been carried out through a wormhole. As a superluminal channel connecting two galaxies, a wormhole can transmit not only matter, but also various communication signals and information including electromagnetic waves, neutrinos, gravitational waves, etc. With the help of a wormhole, no matter whether the two communicators are far apart, they can achieve delay-free communication with almost unlimited bandwidth. Compared with quantum communication that requires a huge number of quantum entangled pairs to achieve bandwidth-limited communication, the bandwidth of various signals transmitted by wormholes is almost infinite. From today, all galaxies of the Sky Star civilization will be able to rely on wormholes to achieve delay-free superluminal communication and information transmission.

"You're moving pretty fast..." In the Kalyas twin star system, through the giant base station pair of local light quantum entanglement communication devices, Kalyas saw the brief information about the completion of the first pair of star gates between the mother star system and the star system where the A001 neutron star power generation facility is located. Kalyas looked up at another picture on the huge holographic projection screen. In the Kalyas twin star system, there is also a star gate with a diameter of 1500 kilometers, which was completed a few minutes ago and is about to be tested for the activation of the wormhole channel. The Fenghua elf girl Kalyas couldn't help but feel very happy about this.

"At a time like this... maybe everyone should celebrate?" Kailias turned his head and looked at the more than 600 compatriots sitting neatly behind him and asked loudly?

"Agree!"

“Agree!!”

“I fully agree with this!!!”

Behind Kellias, the more than 600 crew members of the Salem, who were also looking at the huge holographic screen, clapped their hands happily and cheered joyfully. They were looking forward to the upcoming opening of the stargate wormhole channel in the Kellias twin star system. Everyone was eager to celebrate this historic moment. After the stargate opened, even spacecraft without the ability to travel at superluminal speeds could rely on the stargate to travel unimpeded between the various galaxies of the Sky Star Civilization without being affected by the relativistic time dilation effect of near-light-speed travel. The more than 5000 colonized galaxies of the entire Sky Star Civilization, which were originally scattered among the stars, will truly become one on the physical level in the future. The flow of people and materials in each galaxy will no longer need to spend dozens or hundreds of years on long near-light-speed travel. They only need to pass through the wormhole channel at the center of the stargate to instantly reach another star system several or even hundreds of light-years away.

"Salem! Let's go to the ecological park and have a party! Everyone on the boat should participate. Please help me prepare all the food and fun things. We are going to celebrate properly!" The pink-haired elf girl happily instructed the red-haired catgirl artificial intelligence assistant beside her.

At the great historic moment of the first intergalactic wormhole created by the Sky Star civilization, Calisi and others also boarded their Grey Wind mothership to witness this moment in front of the star gate on the mother star system side of the Sky Star system. A large automated unmanned colony spacecraft from the A001 neutron star power plant appeared on this side from the water-like surface of the wormhole interface. The four-member group Yu Luoying and the Sky Star civilization delegation who came with them also applauded happily. Elena, who came with the spacecraft, was driven by high emotions and gave Luoying a big hug. Luoying, who was hugged, also blushed slightly.

"Sister Luoying...you and your companions...no, I should call you sisters now, you are simply our lucky stars!"

"The first intergalactic wormhole channel in the history of Sky Star civilization... Do you know what this means to us?"

"Um... does traveling across galaxies save time?"

"It's not just that... It means we have a stable, intergalactic, superluminal infrastructure, just like the highways and high-speed rail lines your civilization has built to facilitate the efficient flow of materials and people between different locations. Our previous lightspeed spacecraft were like cars that could only be driven in the wilderness with poor road conditions, unable to effectively circulate materials between the galaxies under our control. But with the superluminal technology you provide, like this wormhole before us, it's like we have high-speed rail and highways. Combined with superluminal spacecraft, which are even faster than our previous spacecraft, we can build a truly integrated, intergalactic civilization."

"The relationship between cars and highways is indeed quite appropriate." Renlong, who was standing next to her, commented after hearing Elena's analogy.

"Yes... In the past, we were more like people who only had off-road vehicles but lacked the technology to build higher-level roads. The anchored wormhole and artificial stargate technology provided by you sisters is the technology to build a highway network that complements automobiles as a means of transportation. With better roads, all types of cars can travel faster."

"With anchored wormhole technology, it means that a transgalactic highway based on anchored wormholes has become completely feasible in terms of technology and engineering. We are no longer restricted by the vast distances between stars and can truly travel across the entire galaxy."

Lina, who heard the conversation between the two, cheered happily.

"Indeed...but...this is just the beginning. If we want to truly make artificial stargates and wormhole networks spread throughout the entire galaxy, we still need a considerable amount of construction time..." Iris on the side poured cold water on Lina who was a little too excited.

"I understand what you mean... After all, things like civil engineering and infrastructure construction require long-term investment." Renlong nodded and said.

"Wait... If building stargates and anchoring wormholes is considered infrastructure construction, then isn't this a kind of civil engineering worker for the Milky Way?" At this moment, Calisi, whose mind was drifting somewhere else, suddenly said something astonishing.

"Damn... I hadn't noticed it until you mentioned it... So, it seems like I've really become a construction worker, building infrastructure for the entire galaxy?!"

"Then doesn't the Sky Star Civilization count as a civil engineering contractor?" asked Aze, who was also nonsensical.

"Pfft... then... don't we become suppliers of raw materials to civil engineering contractors?" Renlong almost spit out a mouthful of salt soda.

"I think your focus is off?" Yuki looked speechlessly at his companions around him, trying to correct the topic that had gone astray.

"But... if the current Sky Star civilization truly wants to deploy superluminal infrastructure like anchored wormholes and artificial stargates across the entire galaxy, then they would indeed be considered hardworking infrastructure builders in a sense, wouldn't they?"

"But thanks to... strong artificial intelligence technology and the existence of fully autonomous von Neumann self-replicating nanomachines, we don't actually have to do anything ourselves during the entire construction process..." Iris added, raising her right hand.

"And have you forgotten? The nanomachines that make up our bodies, the Grey Wind, were originally used for what?"

"It seems Yiling Yisi is also... building a star gate?"

"That's right... We and the Sky Star Civilization are just doing the job we're already best at."

"It may take a long time to spread stargates and anchor wormholes throughout every galaxy and every star in the galaxy, but it is not out of reach for the current Sky Star civilization."

"According to the Tree of Life's calculations, within a hundred years at most, we'll be able to build large stargates and anchor wormholes in every star system thousands of light-years around the Local Bubble and Local Cannon, which are over 1000 light-years in diameter. Within a thousand years, we'll be able to expand to the entire Orion Arm. By this calculation, connecting every one of the 4000 billion star systems in the Milky Way to this superluminal infrastructure network will only take tens to hundreds of thousands of years."

"For those of us who have already achieved immortality, we have plenty of time to accomplish all of this and make the Sky Star civilization truly a Type III civilization spanning the Milky Way. Anyway, I've lived for almost 100,000 years, so waiting another 100,000 years is no big deal." Iris, a Sky Star person born at the same time as Kylias, said nonchalantly.

"Maybe... we need to change... our... concept of time?" Yuki was very clear that the Sky Star girl in front of him, who looked very young, was actually close to 100,000 years old in spirit. However, due to the special life form of the Sky Star people, it was not only the body that was immortal, but also the mental state, learning ability, energy, etc. would always be maintained and remain at the peak of adulthood after the physical body entered adulthood. During the long life, neither energy nor physical strength would decline in any form. This was an important reason why the Sky Star civilization had never encountered any form of development bottleneck from ancient times to the present, nor the social development stagnation common in other civilizations.

Yuuki and Kalisi were very clear that both they and Charlotte and the others who came to Sky Star with them needed to adapt to the slight changes in the concept of time length brought about by the long lifespan. For example, the construction of the Milky Way's superluminal highway, which might take tens of thousands of years to complete, was a very long time for several people. However, for a considerable number of Sky Star individuals who had lived since the origin of Sky Star civilization or from tens of thousands of years ago to the present day, tens of thousands of years of construction time was not a particularly long concept.

"It has a civilization history of 100,000 years, but lacks a sense of vicissitudes. A civilization that is always young and energetic, always like a new civilization, but without those defects of a new civilization?" Yuki sighed as he looked at the very active Sky Alien girls around him.

"I think... maybe we really need to learn a little bit about the concept of time from these 'sisters' of ours?"

Chapter 150 Magnetic Monopole Plant Sunwing

The first batch of 1200 superluminal spaceships that set sail from the Sky Star mother galaxy were just the beginning for the Sky Star civilization. One superluminal spaceship after another rolled off the production line, and one fleet after another was formed, heading for various galaxies outside the Sky Star at speeds exceeding the speed of light. Each fleet was composed of more than a thousand spaceships, and each large fleet would be divided into several smaller squadrons. After departure, each squadron went to different star systems, and after arriving at the corresponding target star system, it built star gates and large anchored wormholes on site. From the perspective of the Tree of Life, the quantum computing center of the entire Sky Star civilization, as the star gates of each galaxy were built and activated, one bright spot after another was lit up on the star map. Every time a bright spot was lit up, it meant that the wormhole of another galaxy among the more than 5000 star systems controlled by Sky Star was incorporated into the wormhole network of the Sky Star civilization.

.........

At this time, more than a month has passed since the first wormhole channel between the Sky Star mother galaxy and the A001 neutron star power plant facility was opened. More than one-tenth of the 5000 star systems on the star map occupied by the Sky Star civilization have been lit up, and stable artificial star gates and wormhole channels have been established in more than 500 star systems. For a while, countless spaceships traveled back and forth between various galaxies through the anchored wormholes created by artificial star gates. The journey that originally took decades or even hundreds of years for inertia-free engine spacecraft traveling at close to the speed of light has now been shortened to just a few days or even hours. The individuals of the Sky Star civilization, whose curiosity and novelty have been aroused once again, have become active more than rarely seen in tens of thousands of years. A large number of Sky Star people are driving their own spaceships to travel between the more than 500 star systems that have completed the construction of artificial star gates.

Similarly, many Sky Star people choose to follow the colonial fleet with superluminal travel capabilities to those star systems that have not yet completed the construction of star gates and anchored wormhole facilities, and enjoy the sense of accomplishment of witnessing one star gate after another being erected in the new star system and incorporated into the wormhole network of the mother star system.

.........

"Speaking of which... can a civil engineer feel a sense of accomplishment even by doing nothing?" Ren Long looked at the various information in the Sky Star Civilization's superluminal data exchange network with shame and a wry smile on his face.

"That depends on how they build the plaster... At least the Sky Star people don't have to build the plaster themselves. In just a few meals, the building materials will build themselves into houses and various infrastructure... The Sky Star people only need to transport the building materials to the designated location. The rest, such as construction and post-construction maintenance, the building materials will take care of themselves."

"Based on the current situation...isn't the Sky Star civilization now a galaxy-scale civil engineering Greyhound?"

"It's just that this civil engineering project... you don't need to do the work yourself. You just need to make a cup of tea, move a chair over and watch the building build itself." Kalisi, who was studying a very special plant in a container in front of her in a laboratory with Yuki, looked up and answered Renlong.

"But I still don't quite understand... Looking at the building materials and piling them up into a building... will there really be a sense of accomplishment?" Renlong was holding a holographic display in his hand, and the image projected on the display was playing a video repeatedly.
