Subspace, a unique space, the space gap in the universe is formed after the space film between the universe and the subspace is broken, such a space gap is very unstable, if there is technology to stabilize it, and connect to other places, such a gap will become a wormhole. [with _ dream]ā

Most of the wormholes in the galaxy are naturally formed by advanced civilizations, and they are used to connect other places, mostly used to transport troops during war, and there are also such things between the earth and the LV-223 planet, which are used by the Kulm people to study in a hurry.

In subspace, because the speed of light has changed, the cosmic constant has also changed in subspace, and civilizations that can enter subspace can truly study space technology, such as storage space, etc., and only by entering subspace can it be possible to cross the river system, and because the distance between the river systems is too far, it is too difficult to build wormholes, and the space technology required to connect wormholes millions of light years away requires very high technology, and ordinary advanced civilizations do not have this technology.

"Our civilization does not have such technology!" Grolls said that the current spacecraft is moving in subspace, at a speed of 400 times the speed of light, and it will take a year and a half to reach the centaur arm, at this time, under Xiao Scar's questioning, he answered some of Xiao Scar's questions.

"How kind of researcher is you in your civilization?" Xiao Zhen asked.

"In our civilization, scientific researchers account for a relatively large proportion, but after the war with the Iron Blood, most of the clansmen have leaned towards fighting, and the number of staff has decreased." "However, our scientific research capabilities have not declined, because war is the first driving force for scientific and technological progress," Grolls said. ”

"In the classification of civilizations in the galaxy, one, two, three are primary civilizations, four, five, and six civilizations are medium civilizations, and seventh** is advanced civilizations, because of the war with the iron-blooded civilization, our Kulm civilization has evolved into a seventh-level civilization in the galaxy, and the galaxy now has a total of two seven-level civilizations, we and the iron-blooded civilization." Grolls said.

Hearing this, Xiao Zhen nodded, and didn't ask any further, the next thing is to wait to reach the wormhole, only through the wormhole can you quickly reach the centaur arm, if you rush directly from subspace to the centaur arm, it will take too long, more than 10,000 light years away, even if it is 400 times the speed of light, it will take twenty-five years.

Twenty-five years, it takes twenty-five years just to travel, he got a shuttle, traveled through countless plot worlds, all the time is not counted at this time, if he wastes time on the road, he is unwilling, with this time, it is better to return and start other plots again, and he can still get biochemical technology and talents.

However, with a wormhole, it is different, and the twenty-five years of travel time has been reduced to one and a half years, and this scarf is still acceptable.

He closed his eyes, looked at the thread of faith linked to the godhead, and began to silently condense his divine power...

Time passed imperceptibly, and a year and a half passed in the blink of an eye.

On this day, Xiao Zhen slowly opened his eyes, and he could feel that the speed of the spaceship began to decrease, from four hundred times the speed of light to three hundred and ninety times, three hundred and eighty times, and at this time, the sleeping cabin next to the seat also slowly opened, and Grolls woke up from his slumber, sat on the seat, and began to operate the spaceship.

"Master, we have arrived near the wormhole, and the spaceship is about to leave the subspace!" Grolls said that while he was asleep, he had set a time to wake up automatically when he was about to leave the subspace.

"Is it there?" Xiao Zhen poked out his thoughts slightly, and felt that the outside of the spaceship was full of streamers, and no matter could be seen, this was the subspace.

Under the control of Grolls, the speed of the spacecraft decreases again and again until it is reduced to the speed of light, and just below the speed of light, the spacecraft automatically leaves the subspace, and the spacecraft that breaks out of the subspace is not traveling at the speed of nearly light, but at the speed before entering the subspace.

As mentioned earlier, the physical constants in the subspace are different from those in the real universe, so the inertia of the speed of light is not brought into the real universe.

The holographic star map is clearly displayed under the control of Grols, and the location of the wormhole is just three hundred lightseconds ahead.

Five hundred light seconds, 1.5 billion kilometers, is not too far, with the flight speed of 100,000 kilometers per second of the Moon Walker, it will take about twenty-five hours to arrive, this year and a half have been waiting, not bad time, although he Xiao Scar can use divine power to teleport, but when he heard the civilization war that Grolls said before, Xiao Scar didn't want to waste his divine power, and he didn't bother to change the Marseille-class spaceship, or that sentence, he has waited for more than a year, not worse than these twenty hours.

In the past year and a half, he has continued to condense his divine power, condensing a total of about six hundred drops of divine power, and around the godhead at this moment, more than six hundred divine powers revolve around the godhead, like countless stars orbiting around the silver heart, bright and beautiful.

Very under the control of Grolls, slowly accelerating, until the maximum speed of 100,000 kilometers per second, twenty-five hours later, the spacecraft finally entered the range of the wormhole, and they were about to leave the constellation Orion, where the solar system is located, and go to the Centaur arm.

This impulse to the centaur arm is very large, with a diameter of about more than 20,000 kilometers, after all, it is a wormhole across the spiral arm, and the civilization that created this wormhole must have considered using such a wormhole to transport troops in wartime.

"Such a wormhole, is there no civilization to guard it? Could it be that this is also made by your civilization? Xiao Zhen asked, if it is a wormhole created by the civilization above Orion, it is impossible not to send troops to guard such a wormhole, after all, this universe is not safe, the two advanced civilizations of the galaxy have broken the sky, and the war has lasted for more than 100,000 years.

"This is indeed a wormhole made by our Kurms, there are not many local civilizations in Orion, the highest level of civilization is a fourth-level civilization, which has been able to carry out interstellar voyages, but if you want to get here, you can't do it with their technology, only civilizations that can enter the subspace can rush here, and the civilization with the ability to navigate in subspace, even if you don't use a wormhole, you can cross the spiral arm by spending a lot of time, so we didn't send people to guard this wormhole, Orion is not our battlefield, Our forces are concentrated near the Silver Heart. Grolls said.

The spaceship entered the wormhole, and after a while, it walked out of the wormhole and came to a strange place, Xiao Zhen's divine mind probed out, and he could clearly see the distant position of the silver heart, those bright stars, their brightness was much brighter than what they saw in Orion, and here, it was the Sagittarius spiral arm!

Because of the black hole in the center of the galaxy, the number of stars gathered around it is very huge, and there is a huge stellar cemetery, where stars are constantly swallowed by the black hole.

The location of the silver heart is rich in materials and has many terrifying resources, which are far from being comparable to rural places like Orion, let alone the solar system, which is not ranked in Orion.

The head of the Sagittarius spiral arm is very close to the galactic center, only separated from the galactic center by the constellation Ruler and the Southern Cross spiral arm, and the tail of the Sagittarius spiral arm is in the periphery of the Milky Way, more peripheral than Orion, more Perseus is almost the same, belonging to the large spiral arm in the Milky Way, and the internal rectangular and Southern Cross spiral arms are mostly close to the galactic center, and its head star group is directly connected to the galactic black hole, and the tail is only Kankan extending to the edge of the river system, and the stellar planetary nebula dust and other materials are far less than the Sagittarius spiral arm and the Perseus spiral arm.

Orion, where the solar system is located, is a small spiral arm sandwiched between the inner Sagittarius spiral arm and the outer Perseus spiral arm, in fact, from the entire Milky Way, although the place where the solar system is located is a marginal area, it is not too marginal, after all, there is still the tail of Perseus at the bottom, isn't it?
