In a large and bright domed hall, there were many people in neat uniforms, most of whom were sitting in their own places busy with the work at hand, a few were talking to each other or arguing about something, and many people were shuttling through the aisles. They almost all hurried with their heads down, and even if they walked face to face with other people, they didn't communicate at all, and they didn't even turn their eyes to each other, like strangers.

In front of the hall is a huge transparent cover, and outside is a pure starry sky, the starry sky is shimmering with stars, these rays from distant stars give this starry sky an inexplicable aura, because in such a lonely darkness only light can show a trace of life.

In the middle of the huge screen, a translucent sign is suspended in it, and the two characters of Kuafu in the seal body reveal a fearless spirit that resonates harmoniously with the atmosphere of the hall, which represents the eternal inheritance of Kuafu, and these people are the successors of Kuafu.

In this busy hall, a slightly deserted corner is out of place with the surrounding atmosphere, and none of the countless hurried pedestrians have visited this corner, and no one even pays attention to it in the entire hall, it seems to be isolated from the world, I don't know if it is a psychological effect, and even the light shining here is darker than other places.

"Ah...... Ha ......"

One of the people sitting here suddenly moved, and saw him stretch his limbs as hard as he could, as if he were about to flatten himself completely, and then paused for a long time before he retracted into his seat, and lazily snorted. With a tingling sensation spreading throughout his body, a sour feeling emanated from the inside out of his nose, and tears couldn't help but ooze out of the corners of his eyes. He squeezed his eyelids, tears slowly flowing down his cheeks, and the sliding tears just made his cheeks itch slightly, and then they were blown out of nowhere by the air current.

The man scratched the traces of tears, and then yawned again. He stretched his arms back and forth, turned his head around his neck, felt his whole body lighten, exhaled in satisfaction, and then turned his head to look at his side.

There, another man sat in his seat, looking at the screen in front of him earnestly, his fingers methodically handling his work. Probably sensing the gaze of his companion beside him, his movements stopped slightly, his stiff body relaxed, and then he fell back to the back of the chair behind him, and also learned from the other party to stretch out his arms, yawned, closed his eyes, and his limbs and body drooped limply.

"Hey! Ay! …… Hachi, pay attention to the image, are we online? Important working hours! You know? Deputy Commander-in-Chief Shaohao is still staring ahead? Watching the other party learn his own movements, this person was a little funny in his heart, but his expression did not show it, but said seriously.

"How dare you say me? Job? Does it seem like I've been doing a good job all along? It's that you've been idle. The other party's physical state did not change at all, and his tone did not show weakness at all, and he replied with a twisted head and stared at his eyes. Also, image issues? I said Jiqing, can you put your feet off the console first, and then say I can do it? ”

"Is there one?" Jiqing still crossed one leg, and he didn't mean to put it down at all, because he knew that in the online hall, the deputy commander-in-chief on the rostrum couldn't see his small movements in the cabin at all, he turned his head, looked at the screen in front of him seriously, and deliberately asked, "Is there anything that needs me to get out of the horse?" ”

"Nope!" Hachichi turned his head with a hum, sat up straight, and continued to deal with his own affairs.

"That's good!" Jiqing suddenly smiled and patted his companion beside him, "Go back and give you a few days off, just make up for your hard work." ”

The other party snorted angrily, and even if he replied, he didn't know if he recognized it.

"Take it easy! This mission was originally only a number, besides, it's just a first-level alert, so what's the danger? Jiqing saw that the other party still didn't react, shook his head, and squinted at the screen in front of him, and the mission notification was blank except for standby.

"Yes! Hachi didn't have a hint, so what would be the task? The corners of Jiqing's mouth curled, and he continued to sit comfortably in his chair.

"Attention departments! Get back to your posts right away! ”

A mid-bass voice resounded throughout the audience, and the originally noisy hall fell silent after a few seconds, everyone stopped what they were doing, and the people walking in the aisle quickly returned to their seats, sitting upright, and everyone turned their attention to the rostrum.

The two people on the rostrum waited for everyone in the audience to be completely silent, and the people standing on the side saluted the people in the central command seat, and returned to their seats, and the people in the command seat began to speak.

"Two days ago, according to the data observed by the Radar Detection Department, with the consent of the command, Kwafu activated the first-level early warning alarm procedure, and we will encounter gravitational winds again. Three hundred years ago, Pangu and Nuwa were destroyed by the gravitational vortex in this gravitational wind. ”

"However, the greatest virtue of human beings is progress, especially since we, as the inheritors of the Kwafu Project, will never fall in the same place for the same reasons. We will only become more and more courageous and learn lessons in order to survive a hundred battles. After so many years of research and preparation, coupled with the scientific and technological assistance of Renhe Civilization, the gravitational wind can no longer pose an existential threat to Kuafu. ”

"However, you still have to be very energetic to fight this crisis, because most of you are new to gravitational winds, and you have no practical experience except for the data and simulation experiments left by your predecessors. When carrying out this mission next, everyone should keep in mind a truth in their minds, there are no absolute things in the universe, and any small accident will not only sacrifice your own life, but also may bury Kuafu's efforts for nearly a thousand years. ”

Deputy Commander-in-Chief Shaohao paused, his eyes swept to the audience, and he looked at almost everyone seriously. Jiqing couldn't help but sit up straight like everyone in the audience at this time, and his eyes couldn't help but look over the two people on the rostrum and look at the starry sky. It was still the same as before, nothing had changed, but he knew that a mysterious force in the universe was rapidly approaching here. This force is furious and ruthless, and like other cosmic phenomena, it operates only according to its own laws until it dies in time and space.

"Good!" Deputy Commander-in-Chief Shao Hao looked at everyone's state and nodded with satisfaction, "I believe that everyone is already familiar with the information of the Pioneer Exploration Fleet, and the simulation training results are also very good, now, let's face the challenge of this universe together!" ”

"Deputy Chief of the General Staff, arrange the task!"

"Yes!"

"Attention to all staff, there is still one hour of contact time, and all departments report on the work process."

"The Sky Eye system is ready, ready to stand by at any time!"

"The Xuanyuan attack system is ready, ready at any time!"

"The Nine Dragons God protection system is ready, ready to stand by at any time!"

"The Nuwa Stone emergency system is ready and ready to be on standby!"

"The Celestial Maiden early warning system is ready, ready to stand by at any time!"

……

"Report to the Deputy Commander-in-Chief, all systems are ready! Please instruct! ”

"Okay, all on call! From now on, enter the wartime state, order the reserve personnel to enter the standby state, and if there is a problem, enter the online at any time according to the plan! ”

"Yes!"

"Holographic wartime system activated!"

"Holographic wartime system activated!" The officers in charge of the General Staff repeated the instructions and quickly initiated the procedure.

As the seat of the deputy commander-in-chief slowly turned to the starry sky behind him, the entire hall began to change, except for the screen in front of him and the little eight beside him, the hall and the Kuafu disappeared around him, and the surrounding became an endless starry sky, such a holographic environment in. Although Jiqing had been mentally prepared, he still couldn't help but shudder by the surrounding environment, this dark space made him feel a cold breath in his heart, and the awe of human beings for the unknown universe was deeply rooted in almost everyone's hearts, especially the Kuafu crew, and the various crises encountered by the generations of Kuafu in the history of the voyage made them deeply touched.

After the scene switched, some colors soon began to appear in it, and all kinds of logos filled the space in front of them with different colors, which was the holographic wartime system, which allowed people to intuitively feel the entire scene from the perspective of the eye of the sky.

The movement of the gravitational wind in front of the spacecraft is marked by a blue image, distance, speed, contact time, and different levels of range......

The location, grade, and predicted direction of gravitational vortices have been determined......

Miniature Qua Father and surrounding ancillary equipment......

Everything is clearly visible,

Under this system, as long as Jiqing casually stretches out his hand or gives a command, he can summon all kinds of information to his eyes.

Although Jiqing has experienced this kind of scene in the simulated wartime system more than once, but when it comes to facing it himself, it is still full of novelty and tension, and human psychology is like this, simulation and reality can always bring individuals a different feeling, making people more nervous and excited.

This plan is the first time that Kuafu has faced gravitational winds since his reconstruction, and it is also based on the preliminary interpretation of Renhe's research on gravitational winds, and the plan is divided into five stages.

In the first stage, the Pioneer Exploration Fleet and the Kwafu speed were adjusted to complete synchronization, and the relative position was expanded to a distance of 6 hours at the speed of the gravitational wind, so as to ensure that the Pioneer Fleet would transmit the data back to the Kwafu after first contacting the gravitational wind, and give the Kwafu sufficient time for analysis and preparation.

In the second stage, two hours before the Vanguard fleet came into contact with the gravitational winds, the fleet set up the same exploration system and defense plan as the Kuafu.

In the third stage, the Pioneer Fleet and the Qua Father came into contact with the gravitational wind, and the Pioneer Fleet transmitted the data to the Qua Father in real time, mainly to explore the detailed data of the gravitational wind and gravitational swirl in the range, and the Pioneer Fleet adjusted the navigation status in strict accordance with the plan drawn up by the Qua Father.

In the fourth stage, the Pioneer Fleet and the Kwafu conducted a gravitational sail acceleration test in the rear area where the gravitational wind was relatively stable, and completed the use and commissioning of the gravitational sail equipment.

This phase is the most important part of the whole program, and the success of the gravitational sail test will raise human space technology to unimaginable heights. Since then, the Kwafu can complete a very high state of acceleration and deceleration without spending a lot of material fuel that is difficult to obtain in the open interstellar space, thereby greatly shortening the navigation time, and the saved energy can also be used for life-sustaining equipment, increasing the sustainability of human navigation and making interstellar navigation more convenient.

Gravitational winds are almost impossible to exist near massive stars, and the number of them in the interstellar open space is previously unimaginable. However, most gravitational wind areas are small and not very strong, so they are not easy to be detected by human instruments at a certain speed, but they do affect the state of astronautics, especially when the speed of navigation is low, the impact is more obvious. This is illustrated by the loss of the tank, where a small deviation from the gravitational winds in the early stage can cause the tank to deviate far from the range that the Kwa Father can receive.

Of course, at a time when humans cannot accurately predict the formation and movement of gravitational swirls, it is still very dangerous to accelerate the gravitational sail for a long time, so this time the Quafu only carried out an acceleration experiment of 120 seconds.

In the fifth stage, after the acceleration experiment is completed, the Kwafu will completely pass through the gravitational wind area, and the distance from the Vanguard fleet will be adjusted again, maintaining the current speed of 2 hours.

At this point, the entire project is over, and the Kwafu will continue to enter the daily voyage phase until the next crisis is detected, or the target system is reached.

"Attention all! Countdown, thirty minutes ......"

"Tiannu early warning system synchronizes speed data...... Imported...... Self-test ...... Complete...... Everything works fine......"

“5、4、3、2、1…… Start ......

He knew that the fog was composed of a large number of tiny spherical objects, the small balls were like a sponge-like porous structure, each small ball was only a few millimeters in volume, evenly and regularly distributed in the space around the Kuafu.

The structure of these balls is very special, very sensitive to gravitational vortices, as long as they are close to the gravitational vortex, they will move or rotate according to a certain law, and the Tianyan system will detect the abnormality at the first time, and analyze at the same time, and in a short period of time, the detailed data of the gravitational vortex can be obtained without the accurate data of the detector.

This system was developed to assist the detection system, after all, the gravitational wind area will produce anomalies, a few gravitational vortices will jump forward, some will disappear, and some will regenerate out of thin air, all of which will escape the capture of the detector with a certain chance.

Speaking of the Celestial Maiden system, its prototype is said to have been born in a generation of Kuafu, who once assisted a generation of Kuafu to fight against the gravitational wind, after that crisis, the high-level at that time was demonstrated several times, and even abandoned, no one expected that it would now develop into a necessary auxiliary system.

"Attention all! Gravitational winds are on alert! ”

Arc-shaped lines began to appear at the edges of the holographic system, and these lines representing gravitational winds continued to move towards Kuafu at a regular speed and change. The distance between each line is not fixed, sometimes close to each other and sometimes far away from each other, and the lines are marked with several values that are obviously unknown, and the values represent the strength and speed of the gravitational wind.

"Attention! Preparing to contact gravitational waves...... 5, 4, 3, 2, 1, contact ...... Execute a three-stage predetermined plan! ”

The gravitational wind tip quickly crossed the Kwafu, and the fog warning system near the Kwafu began to contract and contract regularly, with a frequency like the beating of a human heart. At first, it was very slow, but then gradually accelerated, and Jiqing seemed to inhale a strange cool air, which spread from his lungs to his whole body, and even the temperature around him dropped by a few degrees.

When the system is about to touch the gravitational wind, another interface appears on the system, showing a two-way axis and a continuous set of forward squiggly lines. After several gravitational wind crises, after long-term research, Kuafu found that the gravitational wind is essentially a spatial curvature that changes and advances with a small frequency, and as for why the spatial curvature moves forward like a wave, it is still inconclusive. Because there is no definite fixed coordinate in the universe, and all objects and celestial bodies in space are also in constant motion, and motion is an inherent property of the celestial bodies in the universe, therefore, no one can prove whether the curvature of space is advancing, or whether Kuafu himself is moving into this space with frequent changes in curvature.

The Kwafu is like a small boat riding the wind and waves, floating in this cosmic ocean with huge waves. Jiqing watched the waves continue to crash against Kuafu, and he seemed to be able to hear the slight sound of the hull structure from time to time due to the change in stress.

Soon after, the frequency of the gravitational wind wave line gradually decreased, and the amplitude began to increase, and the original light green became dark green, light yellow, dark yellow, and light red, and the Kuafu had entered the center of the gravitational wind.

As the crest of a huge breaking wave line slammed into the Kwafu, the hull of the Kwafu spun uncontrollably at an angle, struggling to climb up the virtual wave. At the same time, the gravitational acceleration inside the ship increased rapidly, and Jiqing felt as if his whole body was constantly diving into deep water, the air around him became viscous, and every breath was very difficult. The capillaries in his body are also constantly congested, especially his eyes are covered with red bloodshots, and his nasal cavity and esophagus are faintly salty.

When he felt a little overwhelmed and wanted to spew something, the ship crossed the crest of the wave and rushed down towards the trough. The frozen air and the body under the weight change in opposite directions again, but the speed of change is so fast that it gives the illusion of weightlessness, and in fact, the gravitational acceleration here is still above the normal value. Kwafu and the crew did their best to resist this cyclical change, and the usual well-prepared workouts ensured that everyone could persevere, and no one had fainted due to the regular change in gravitational winds.

Occasional swirling changes began to appear in the fog, and everyone knew that this was the most dangerous gravitational vortex in the gravitational wind, and the gravitational change in the vortex was so great that in rare cases it could almost change the shape of a dense neutron star.

These gravitational swirls stirred up the fog that had been distributed regularly, leaving empty in some places and piling up in others. The small balls that formed the mist collided with each other, flying around Kua Fu in a chaotic manner, a few of the small balls flew out of the edge of the warning area of the original area, and some of them crashed into the hull of the ship, and in rare cases were destroyed by the force of the whirlpool. This situation was not beyond the calculation range of the Tiannu system, and the system quickly adjusted the algorithm and continued to monitor the gravitational vortex within the range.

"Not good!"

Ji Qing saw that a whirlpool suddenly appeared in front of Kuafu, this whirlpool was very close to Kuafu, and it was difficult to dodge the past depending on the situation, but the three types of contact alarm did not sound.

"The strength of the whirlpool is level three, pass through it directly, and don't change the course." An order was quickly issued from the command platform.

After meeting the whirlpool, the hull of the Kwafu was twisted at an angle, and the course was also deviated, but it soon returned to the original course under the adjustment of the power department, and the whirlpool that was crossed by Kwafu did not change, and after stirring up the small ball fog even more, it flew out of the warning area after a while.

Sometimes the swirls are so strange, sometimes they are stable, sometimes they disappear suddenly, as if they are invisible, and then they suddenly appear somewhere else.

After passing through this whirlpool, Ji Qing breathed a sigh of relief, nervously watched as the Kuafu successfully passed through the center of the gravitational wind, and soon entered the back section of the gravitational wind, and the online hall had already begun to prepare for the first gravitational sail test.

At this time, an unexpected situation occurred, the amplitude of the curve that had been gradually weakening suddenly increased, and it was instantly close to the strength of the central area, and there was a tendency to continue to increase, and the strength of a vortex that appeared also exceeded the top limit of this data, flashing at the edge of the warning circle, making the online hall extremely quiet for a moment.

"Attention all! Level 2 Alert! Repeat! Level 2 Alert! ”

A sharp voice broke the silence, and the atmosphere in the hall suddenly became chaotic, and many people were confused by the large number of orders that burst in, which were beyond the plan and clearly inconsistent with the information transmitted by the Pioneer Exploration Team.

"What's the situation!"

Jiqing, who was originally relaxed and freehand, was taken aback by the sudden alarm, and immediately turned his head to look at Hachi beside him, Hachi also looked at him in a daze at this time, and then his eyes flashed a few times, and almost in front of Jiqing's eyes showed a new command At the same time, Hachi replied: "It's a gravitational wave anomaly!" ”。
