In the dark universe, one hundred fourth-generation 'Xuanwu' ships soon entered a sub-light speed flight state, like a streamer, constantly flying away from the gravitational influence of the star at a speed of 230,000 kilometers per second, and began to enter the curvature flight state.

The gravitational pull of a typical galaxy is tens of billions of kilometers in diameter, and the distance to the next galaxy is hundreds or thousands of light-years

Due to the uncertainty of the existence of the 'wormhole', the 'Xuanwu' fleet was unable to take advantage of this shortcut, so it developed another path, using the gravitational field, developed a super curvature engine, and embarked on the direction of curvature flight.

Using the gravitational field to bend the curvature of space-time sight is not too esoteric aerial technology, but it requires a huge amount of energy to change the structure of the gravitational field.

A single gravitational field is like a celestial gravitational field, and the curvature of space-time is the same in all aspects and angles, such space-time is like the water surface of a lake descending in front of it, and the water surface on the left and right behind it also descends synchronously, and finally it is relatively equivalent to unchanged, and cannot push the boat to move.

The curvature engine creates a large-area gravitational field collapse effect, and after multiple gravitational fields interfere with each other, the multiple gravitational fields finally form an irregular gravitational field that can change the direction of space-time curvature,...... Through the change of the curvature field, the path of the spacecraft is changed, and finally, the spacecraft breaks through the space limit of the speed of light and enters another level of space navigation.

The 'Xuanwu' fleet that entered the curvature of the voyage was moving forward at an extremely fast speed in the distorted space, although the speed was far from being comparable to the convenience of shuttling through the wormhole, but it was still a voyage in space, and the speed far exceeded the speed of light in the stationary space thousands of times faster.

The stars are turning, time flies, and half a year has passed in a blink of an eye.

The Xuanwu fleet suddenly broke free from the curvature navigation state, and the Xuanwu flagship command room, the alarm sounded.

"Alert, arrive at the near zone of the star cluster, detect abnormal energy fluctuations ahead, immediately terminate the curvature voyage, wake up the commander!"

"Alert, arrive at the near zone of the star cluster, detect abnormal energy fluctuations ahead, immediately terminate the curvature voyage, wake up the commander!"

……

Zhou Xiaozhi's sharp voice echoed in the flagship command room, and it didn't take long for a 'snort' sound to sound in the dormant room, and pieces of thick dormant hatches opened, emitting bursts of thick mist.

Zhou Yu's eyes widened, he woke up from his sleep, and was soon helped out of the sleep cabin by two service robots standing aside.

"What happened, have we arrived at our destination?" Zhou Yu looked at Zhou Xiaozhi standing in front of it in confusion, and asked a little weakly.

"Commander, the fleet has not yet reached its destination, however, it has detected an anomalous energy fluctuation ahead, and if it continues to sail with curvature, it may be affected and lead to the destruction of the entire army. Zhou Xiaozhi looked at Zhou Yu and reported.

After speaking, Zhou Xiaozhi released a holographic screen in front of Zhou Yu, and in the screen, a vast starry sky appeared, and the star cluster in front of him was the brightest and dazzling, which was the collision of dense interstellar dust particles of the nebula, resulting in a magical phenomenon.

Under the high-speed impact of the particles, a large number of X-rays are emitted. Along with the X-rays, there is also light in the visible light band, this light, showing a faint pink, dyes the starry sky in front of it into a red cloud, and at the same time, an unusually powerful light explosion occurs from time to time, but the field of vision is blocked by the pink 'nebula', and it is impossible to see what is happening in the depths.

The scene in front of him immediately attracted Zhou Yu's attention, and he held the two serving robots, stood up straight, and ordered, "Stop moving forward immediately." ”

"Obey, Commander!" Zhou Xiaozhi responded, and immediately, the Xuanwu fleet turned off the engine thruster and slowly lowered its flight speed.

"Abnormal energy fluctuations, have you confirmed the reason, is there something wrong with the UC22 star cluster?" Zhou Yu looked at Zhou Xiaozhi and asked.

"Lack of effective observation data, it is impossible to determine the cause for the time being, and there is a 75% chance that it is caused by the violent activity of the star system inside the star cluster!" Zhou Xiaozhi looked at Zhou Yu and replied.

"Unknown?" Zhou Yu frowned, and muttered to himself, his expression solemn.

Interstellar navigation does not tolerate the slightest sloppiness and recklessness, once there is an accident, the fleet of light ships will be damaged, and the ships will be destroyed and killed, and there is no possibility of escape in the entire unfamiliar galaxy.

"Xiaozhi, how about bypassing the UC22 star cluster, how much more time is it expected to take?" Zhou Yu thought for a long time, looked at Zhou Xiaozhi and asked.

"It is possible to bypass the star cluster, but the area covered by the star cluster in front is too wide, and if you detour, the fleet will have to travel at least 5-7 times longer to reach its destination. Zhou Xiaozhi looked at Zhou Yu and reported.

Hearing this, Zhou Yu's face sank slightly, in order to avoid causing trouble to the 'Tinder' civilization star, he deliberately chose a galaxy more than four hundred light-years away, this curvature voyage took a long time, and if the time was increased by 5-7 times, it would be fine!"

"Commander, otherwise, we can change the direction to something else, like the TN232 system, or here, the XYB111 system,......。 Zhou Xiaozhi looked at Zhou Yu and suggested.

Zhou Yu frowned, a little dissatisfied, the two galaxies pointed out by Zhou Xiaozhi were not ideal targets, one was too far away, and the other was that there were fewer planets: "There are no suitable optional targets?"

"Commander, the other galaxies in the vicinity are single stars, and the right star system is too far away from us, and the nearest galaxy is 2-3 times larger than the original target. Zhou Xiaozhi looked at Zhou Yu and replied.

Zhou Yu looked at the holographic screen and frowned: "Ash, can we pass through this layer of star clusters, is it risky?"

"Commander, this cluster has 12 stars, they are very close to each other, forming a complex structure of traction, the largest of which is this one, I will call it an A-class star, and to pass through this star map, it is best to pass through the edge of the A star. Zhou Xiaozhi explained in detail to the internal structure diagram of the Traveling Warrior Star Map.

Zhou Yu frowned, and just when he wanted to say something, he was interrupted by Zhou Xiaozhi: " Commander, from the analysis of the particle structure, the nebula energy particles covered by this layer of the cluster are not violent, and the spaceship shield is enough to resist their invasion, however, the star inside the cluster I call it the B star, its color is yellowish-white, this color indicates that its surface temperature is higher, correspondingly, its mass is also relatively large, about 127.9 million kilometers in diameter, the solar wind often erupts, and the internal planetary system has 11 planets orbiting around him, but the orbit is now in an unstable state,...... The planetary system of the galaxy is bad, and there should be no intelligent civilization, so as long as you pay attention to the changes in the state of the stars, there should be no other dangers. ”

Depending on the surface temperature, the star will appear in different colors, from low to high, red, yellow, white, and blue. Generally speaking, the higher the surface temperature of a star, the more massive it is, but it is not absolute. For example, the red giant star is also red in color, but it can be many times larger than a red dwarf. It has a red color because it reaches the end of its life, when it grows in size and its temperature decreases.

Generally speaking, the orbit of the planets orbiting the star is predictable, for example, the Earth, at a certain time of the year, the distance from the Sun is fixed, even if there is an error, it can be ignored, which leads to the Earth's orbit is also stable. But not with the planets of this galaxy. At a certain point in time when the star is orbiting, there are often big changes from the previous week to the current week. This means that its orbit is extremely unstable. It is clear that this instability is due to gravitational perturbations from the rest of the stars.

"Are you sure there are no sapient beings? What's going on with those bursts of anomalous energy? How do I feel something is wrong? Zhou Yu frowned and looked at the star map displayed on the holographic screen, seriously skeptical.

"Commander, that's the occasional burst of material transfer between stars, mostly from other stars to the central star, and this cluster continues to operate in this state, and in hundreds of millions of years, they may eventually produce a supernova explosion and condense into a giant star!" Zhou Xiaozhi deduced the results and reported to Zhou Yu.

After Zhou Xiaozhi's introduction, Zhou Yu's eyes widened, and he couldn't help but exclaim: "What a magical celestial phenomenon!"

It seems that it is right to leave the group for an interstellar voyage, otherwise how could it be possible to observe this magical astronomical imagination at close range, for a while, Zhou Yu was relaxed and happy, and became full of pride, this is the life he dreamed of!

"Then what are you waiting for, since the risk is not great, start it immediately, and pass through this star cluster with the fastest efficiency. Zhou Yu looked at Zhou Xiaozhi and commanded.

"Yes, Commander, but I would like to report to you in advance, because the state of the star explosion of this cluster is too complex to sail at curvature, otherwise we will not be able to escape in the event of an accident, so we can only sail at sub-light speeds. Zhou Xiaozhi looked at Zhou Yu and reported.

Hearing this, Zhou Yu's face changed, and he hurriedly asked, "Then how much time will it take us to pass this star map?"

"About 3-5 months, if there are other unexpected changes, this period may be extended. Zhou Xiaozhi looked at Zhou Yu and reported uncertainly.

Zhou Yu was silent for a moment, and finally couldn't resist the temptation to explore this star cluster, and ordered Zhou Xiaozhi: "Go ahead! ”

"Understood, Commander!" Zhou Xiaozhi took the order, and in an instant, the flight speed of the Xuanwu fleet suddenly increased, and it continued to approach the star cluster.

Since there is no diffuse reflection in the universe, the cosmic matter, whether it is a planet or a spaceship, when it is close to the star, is day on the side facing the star, and night on the side facing away from the star. But after this star cluster, there is no such thing as night. The Xuanwu fleet, whether it was front or back, front or back, left or right, was all illuminated by these stars.

As time passed, the Xuanwu fleet gradually flew into the star cluster and visited this mysterious world.

Soon, a giant planet around an A-class star came into Zhou Yu's eyes.

Sensing Zhou Yu's attention, Zhou Xiaozhi immediately presented the structure, parameters, and form of the entire planet on the command screen.

Zhou Yu's eyes widened, and he saw the structure of this planet clearly, and he had to marvel at the magic of the universe again.

The surface of the planet presents a smooth ground in the form of black crystals, with almost no ups and downs, no mountains, no valleys, and the whole is extremely smooth, like a black glass ball, shimmering with a dark luster.

"What's going on? How did this planet become like this?" Zhou Yu looked at the planet in front of him and asked Zhou Xiaozhi puzzled.

"Commander, those black surfaces are all melted rocks, which have been close to the stars countless times in the past, and then burned by the massive heat of the stars, causing the rocky surface to melt away, and then when they are far away from the stars, they have cooled and condensed again, and continue to melt until the next time they get close to the stars,...... In this repeated process of condensation, melting, condensation, and melting, all the geological details of its surface were erased, so it ended up like this. ”

"This planet does not have any atmosphere, even if it had an atmosphere when it was first formed, it will be stripped by the stars, just like now, it is about 70 million away from star A, less than half the distance between the earth and the sun, plus the star of star A is very active, in such a short distance, even the atmosphere of more than 1oop kilometers thick on the earth will be completely stripped away in tens of thousands of years. Zhou Xiaozhi deduced the trajectory of the planet and explained to Zhou Yu.

Under the illumination of star A, the temperature of its surface reached about 400 degrees Celsius, and the surface of the rock emitted a dull red light, like a terrifying lava hell, shimmering with a dark luster that was devoured by people.

"The environment is so harsh, this planet should not be able to form intelligent life. Zhou Yu showed a sudden look, sighed with emotion, and continued to instruct Zhou Xiaozhi: "Look at the situation of other planets." ”

"Obey, Commander!" Zhou Xiaozhi answered, and immediately, the planets appeared on the command screen one after another.

The shapes of these planets are similar, and they have been devastated by the stellar group in this cluster, which makes their body color biased towards and heavy color, either red and shiny, or black and terrifying, and even like bright silver planets, which have been polished into a metal sphere in time, reflecting a dazzling silver luster.

Just when Zhou Yu squinted and was intoxicated, in the command screen, a silver light suddenly flashed, and a silver beam of light was cold, shooting towards them from the silver planet at a rapid speed.

"Encounter an unknown enemy attack, encounter an unknown enemy attack......" Zhou Xiaozhi reminded loudly.

"The fleet immediately evasive, defensive state, maximum power output of the energy defense cover, Xiao Zhi, quickly find out the enemy!" Zhou Yu was in danger and ordered decisively

"Obey, Commander!" Zhou Xiaozhi immediately carried out the order.
