In a conference room next to the main control room of Xingtu, Lin Xi was analyzing the things to pay attention to and some technical issues that need to be overcome with the voyage of the river.

The space-time energy engine was manufactured to reach a level 6 civilization, and the long-distance voyage in the river galaxy cleared the obstacles, but the space-time characteristics of the dark domains between the river galaxies are needed, so some specialized research and development instruments are needed.

"Aunt Lin Xi, there is no problem with these instruments. Is it not safe enough to plan two black holes as space-time anchors?

After all, this is our first long voyage in the river, and the error tolerance rate of the two black holes is too low."

During the long voyage of the river, the function of the black hole is to act as a space-time anchor point, as a collapse in space-time and collapse into the level of nothingness in the event of mistakes, and to be used as a fixed point.

If a neutron star or a white dwarf falls into the level of space and space in the dark domain, even if the space and space are repaired, the neutron star and white dwarf will disappear. On the contrary, if a black hole falls into the level of space and space and space, the black hole will be "snatched out" like an anchor sinking to the bottom of the water.

"With multiple white dwarfs as energy supplement, every time the wormhole crosses, the space-time energy expansion and stability of the wormhole must exceed 20% of the theoretical calculation before crossing. If the first crossing occurs, the first crossing will increase to 80% before crossing before crossing."

Xu Xiaobai walked in and said ignoring Lin Xi's rolling eyes.

Black holes are not that easy to carry, especially carrying black holes through the dark domain, which is much more difficult than carrying hundreds of white dwarfs.

After looking at the data displayed on the screen, Xu Xiaobai calculated the resources required for this long voyage in the river system in his mind, and he couldn't help but feel a little shocked.

There are 350+ white dwarfs, 110+ neutron stars, and 2 black holes. If you come like this several times, you will lose weight in the Milky Way.

After the guinea pigs went out to conquer and study instruments dedicated to the river voyage and control warships to capture white dwarf neutron stars and black holes, Xu Xiaobai sat down next to Lin Xi.

"When the river straits, you need to divide into two teams. Then you and me will join us, and the teenage mice will control another team."

"Whoever is with you, drive a warship by yourself. When you fall and lose control, we will return to the Milky Way and slowly pass by in the closed space and space."

Lin Xi glared at him angrily, but reached out to hug Xu Xiaobai, and put his chin on Xu Xiaobai's shoulder. He didn't know what he was thinking.

Unlike the Dark Star Civilization's long-distance voyage, Xu Xiaobai did not use the gravity of the Milky Way celestial bodies to open up a path of time and space first, but directly brought a row of white dwarf neutron stars and rushed into the dark domain with a black hole.

389 white dwarfs, 121 neutron stars, and 2 black holes. This is the travel expenses for Xu Xiaobai's long-distance voyage to the m33 galaxy.

All white dwarf neutron stars use special gravity shielding instruments to block the leakage of space-time fluctuations. The space-time collapse around the black hole was repaired and fished out by the space-time control instruments. The battleship team circumvented in the orbits of the two black holes.

Outside the battleship, a large number of space-time controllers form a Dyson ball-like enclosed layer, which isolates the leakage of space-time distortions and fluctuations caused by black holes.

"The wormhole opened 48,000 light years!"

After mastering the core theory of the Great Unification and realizing the transformation of matter and time and space, Xu Xiaobai and his team almost fully understand space and space, and the distance between space wormholes easily exceeded 10,000 light years, and the farthest reached 98,000 light years. It can be said that one time travel is a galaxy.

Of course, the longer the wormhole in the dark domain, the better, it involves the outflow of space-time energy.

Space-time is repairable, and the space-time in the dark domain is too weak. The wormhole needs to inject a large amount of space-time energy to stabilize before it can travel. During this process, space-time energy is leaking out at all times, which requires special instruments to block space-time.

But even a blockade cannot achieve a 100% blockade, so it is not that the longer the wormhole, the better. This crossing length requires strict analysis and measurement, and a middle value with the best cost performance is obtained.

During the long voyage of the river, the distance of millions of light years is unreliable. The distorted space-time and space collapse in minutes. Space teleportation and space jumping is a pit. Only space wormholes are the best way to sail in the river.

"White dwarf cutting, super-large space-time energy engine is prepared, converting white dwarf matter, and slowly injecting space-time energy into the wormhole."

A white dwarf has a density of one cubic centimeter and weighs several tons, and its image is like a small finger weighs several tons.

Even so, the white dwarf is still in the scope of space-time and space. Relying on the existence of space-time, facing the space-time cutting formed by precise extraction of space-time energy, the white dwarf is cut without any resistance.

The powerful control instruments around it also prevent the loss of the white dwarf mass and its own gravity from falling, and the explosion of electron degenerate pressure can no longer be overcome.

A large amount of space-time energy is converted and slowly injected into the space wormhole thinly into the bullet hole. It is like blowing air, and the space wormhole slowly expands.

Bang!

Before it could be fully opened, the energy in time and space was injected too strongly, and the same weak wormhole in the weak space and space of the dark domain collapsed.

"The wormhole opened for the second time."

On the Xingtu account, Xu Xiaobai was not discouraged when he saw this scene and gave the order calmly.

Next to it, Lin Xi was checking the data of the first wormhole expansion and stability failure, thinking about further optimizing the large space-time energy engine, while Molly was watching with Lilith and the others.

The 48,000 light-year wormhole opened again, and the space-time energy was slowly injected into the expanded and stable wormhole. This time, the wormhole was successfully expanded to a super-large wormhole with a diameter of 2,800 kilometers, which was enough to allow the relatively large white dwarf to pass through.

Four white dwarfs were cut and converted into space-time energy and filled in. During the filling process, small wormholes with increasing distances were also opening.

A space-time controller is constantly passing through small wormholes, coming to the space-time coordinates of the main wormhole, connecting them together to block time and space, reducing the diffusion and passage of space-time energy on the main wormhole, and maintaining the stability of the main wormhole.

When the four white dwarfs were completely consumed, several warships carried a neutron star into the wormhole.

On the huge screen, the signal showing that this neutron star is constantly passing through the wormhole in the simulation screen. During this process, the fifth white dwarf is still being cut into a space-time energy-stable wormhole.

In two days, the neutron star arrived safely. Xu Xiaobai began to remotely control the warship to cut the neutron star matter, convert it into space-time energy to stabilize the space-time, and at the same time slowly unleash the gravitational shield that releases the neutron star, and finally relies on the neutron star to form a relatively solid space-time node.

The time and space nodes were built, and the mice on this side of the wormhole began to control the curvature engine, twisting the time and space to slowly enter the wormhole at the black hole anchor point.

After the teenage mice arrived safely at the other side of the wormhole, a row of white dwarfs and neutron stars that were blocking gravity also lined up to enter the wormhole. Then Xu Xiaobai controlled to drive the black hole anchor point into the wormhole.

The wormhole was closed, the instrument stopped, and the neutron star in the place lost control and instantly destroyed the space-time and space, falling into the level of nothingness, leaving behind a weak space-time and space-time that was slowly repaired.

Unlike the Genda Civilization Combined Fleet who traveled through the dark domain, Xu Xiaobai did not go directly because he had only two black holes. Instead, he asked the neutron stars to go there first to establish a space-time node, and then officially passed.

Implement Xu Xiaobai's policy of rather waste than make mistakes. Every time I build a wormhole, it increases the consumption by 20% compared to the theoretical calculations, and the long voyage of the river galaxy goes smoothly.

"Is this the dark domain?"

In the middle between the m33 galaxy and the Milky Way, at Molly's request, Xu Xiaobai opened up the synchronization between Xingtu and the outside world.

In an instant, the main control room of Xingtu was transformed into a holographic ar scene and synchronized with the outside world.

In addition to the distant mm3 galaxy, the Milky Way and Andromeda galaxies emitted a little hazy light, and the entire sky was completely dark.

Being filled with it, feeling the darkness all over the sky, a feeling of loneliness suddenly appeared in my heart.

But this is not really dark, it is just lower than the visible brightness of the human eye.

Xu Xiaobai reset the scene again and refreshed the scene. The data detected by detectors revealed the existence of other galaxies in the more distant Virgo supercluster.

Xu Xiaobai set up the data to refresh it again, and added the space-time detection data. In addition to the range of the space-time nodes, the low and weak fluctuations in the space-time outside the dark domain made people frown.

Simple calculation analysis shows that in the dark domain space-time in the center of the two major rivers, let alone black holes, matter with a density of more than 86.5 grams per cubic centimeter can be suppressed across space-time, causing space-time to collapse.

This one withstands an extreme density lower than the core density of the star.

In other words, even if a star is placed in the space-time environment here, if it is not controlled by humans, the star will crush space-time and fall into the level of nothingness like a black hole.

Matter determines time and space, and the starry sky with abundant material is more stable.

However, unless the time and space in the dark domain are artificially enhanced and reinforced, materials with slightly higher density appear here before they can stabilize time and space, they will crush and collapse.

Not only matter that affects time and space, but energy can also affect time and space. Clicking a nuclear bomb here can explode time and space. The faster the speed, the higher the energy. The accelerated matter is less than 200,000 kilometers and it will penetrate time and space every second.

Here, the ultimate velocity of matter is 200,000 kilometers. Only particles without mass like photons can reach the speed of light.

"Stay on."

After watching for a while, Xu Xiaobai closed the scenes in synchronization with the outside world, and the main control room of Xingtu was restored to its original state.

Here, white dwarfs burn at every moment. Every time they stay, a large amount of matter needs to be converted into space-time energy to maintain it.

The fleet circumvented the black hole and continued to cross the wormholes with a series of white dwarf neutron stars. As the remaining distance shortened, the number of white dwarfs and neutron stars carried was also decreasing.

There is not no matter in the dark domain. Occasionally, some interstellar dust, some frozen interstellar gas, and even some stray meteorites and wandering planets slowly move in the dark domain and rush towards the dark front.

These substances, meteorites, and wandering planets, have no speeds of more than 50 kilometers per second. They may be driven out by galaxies or abandoned by some boring civilization, but no matter what, they are destined to never be able to cross the dark realm.

Poor speed, long distance, and a desperate journey of tens of billions of years, the universe might end at that time.

As the distance from the m33 galaxy became closer and closer, the starlight of the Milky Way behind became dimmer and dimmer. Lin Xi and Molly became a little silent. They walked to Xu Xiaobai and sat down, quietly watching the rows of data that were refreshed from time to time on the screen.

Beep beep beep beep...

Just after completing a crossing, Xingtu suddenly detected abnormal data. After returning to Earth from the Southern Cross Arm, a sudden alarm that had not sounded for many years suddenly sounded.

The red light flashed, and it was obvious that the abnormal data detected this time was at a high risk level in the evaluation of Xingtuo intelligent system.

"How far is the m33 galaxy?" Xu Xiaobai asked Xingtu.

Lin Xi immediately stood up and ran to the main console to analyze the abnormal data. At the same time, a piece of data was sent to the guinea pigs.

"There are 980,000 light years left before the m33 galaxy!" Xingtuhao replied.

980,000 light years, this is still the real dark domain space-time. An unexpected situation is detected here. Once a war occurs, it may not necessarily be necessary for everyone to bury space-time.

"The source of the signal is abnormal space-time fluctuations, which are about 1,380 light years away, and the specific situation has not been analyzed yet."

A few minutes later, Lin Xi raised her head and spoke a simple analysis of the information.

For the sixth-level civilization, 1380 light years is like playing house, which is a very close distance.

"Slowly release the space-time isolation and blockade of space-time nodes, allowing space-time energy to replenish and spread into the surrounding space-time."

Xu Xiaobai calmly ordered, and after saying that, he asked, "How long will it take for the teenage mice to cross the wormhole?"

There were no accidents when there were many wormholes. Later, Xu Xiaobai and the little mice did not tell who passed through the wormhole first. This time, Xu Xiaobai passed through the wormhole first, and the little mice were still behind.

"There are also white dwarfs and neutron stars that need to come first, and it will take 26 days for the teenage mice to completely pass through the wormhole!"

Molly replied on the other side: "How many white dwarfs and neutron stars are we carrying this time? Do we need to abandon some of the white dwarfs and neutron stars and let the guinea pigs come first."

In recent years, although Xu Xiaobai's status has been declining at home and has become a family cooking man, if something urgent happens, all the decision-making power will be under the hands of Mr. Xu, and he will decide everything.

"No need, the space-time node space range is relatively small, and the layout is in sequence. Abandoning white dwarfs and neutron stars requires re-adjustment of the layout and queueing into the space wormhole, which will take longer."

Xu Xiaobai shook his head and looked at the data that was being refreshed on the screen. The situation where a large amount of data was detected was contrary to the calmness of the previous journey.

"Split some of the warships leaving the space-time range of the black hole, protect the main wormhole, and open the wormhole to the coordinates of the abnormal signal source, inject space-time energy into the stable position and then send the detector to the next level."

Xu Xiaobai issued a second instruction, and various high-power deep-time and space-time active detection methods in the dark domain cannot be used. The fastest way to understand the situation is to open the wormhole and send a detector.
