Click...... Click...... Click...... Boom......

A sound from small to loud accompanied by a sense of vibration from weak to strong, and soon developed into a loud muffled sound that spread throughout the ship, everyone felt this unusual situation, stopped what they were doing, and reflexively looked up in the direction that seemed to be the sound coming from.

The last sound, though not very harsh, brought a greater sense of vibration to the whole ship, and the combination of the two senses gave people an unknown fear in their hearts. The crew members, who were very close to the location of the sound, quickly reacted, reported the abnormal situation, and handed over their work to the central accusation center in accordance with standard procedures, put on their personal emergency equipment neatly, and still stuck to their posts, waiting for the next instructions at any time. Before the order of the superiors was issued, the comprehensive maintenance department began to explore the whole ship remotely, especially the direction of the sonic boom was explored, and the maintenance robot drove out from various parking locations like ants and quickly sailed in all directions.

Jiqing's first reaction was that something big had happened, and it was definitely not an ordinary situation for Kuafu to produce such a shock in the empty cosmic space. He carefully distinguished, and felt that he was far away from the source of the sound, but he was not very sure, due to the special environment of sound propagation in the cabin, people could not distinguish the source of the sound. Sure enough, shortly after he had prepared his emergency equipment according to standard procedures, the lights around him switched to orange, turning the peaceful environment of the bright white cabin a little oppressive.

Immediately after that, the red light flashed three times in a row, and a serious voice echoed.

"Attention! Level 3 Alert! Note! ……”

"Position YHPL0319, Repeat ......"

"After the personnel of the route planning department and the radar detection department in the affected area completed the command center in the work handover, they urgently transferred to the scheduled No. 03 temporary work warehouse, and the personnel of the two departments immediately went to the No. 03 temporary work room to report and prepare for the online ......"

"All the first-level personnel of all posts are assembled, all the second-level personnel are on standby, and other personnel pay attention to receiving notification information! Repeat ......"

"Hachi, what's the situation now!" The communications department area was not affected, and Jiqing breathed a sigh of relief and quickly entered the online standby state.

"A shell of the main body in front of the right side of the Kuafu suddenly ruptured, causing thin pressure in the adjacent area, and the number of casualties has not yet been determined. Now the location of the accident has just been determined, the affected area has been closed, the maintenance robot carrying emergency tools is rushing to the target location, and other conditions have not yet been determined. ”

The rupture of the hull is a very serious accident, but the warning of the three-level alarm is still within the completely controllable range for Kuafu, and it is not a big crisis, if it reaches the situation of the fourth and fifth levels, the Kuafu is very dangerous.

"Was it a small meteorite impact?" This kind of prediction is very common, there are many such small celestial bodies in space, most of the speed and destructive power are enough to destroy the structure of the Kwafu hull, although the asteroids are relatively few in the open space between the stars, and the volume of Kwafu is also small compared to the vast universe, but there is still a probability that the two will meet.

"There is no advance warning from long-range and proximity radars, and it is impossible for a small celestial body to be fast, because if it did, the meteorite should have penetrated the Kwafu, even if it was very dense, and it would not only destroy the outer shell."

It's not a meteorite, it's strange, the current human beings can predict the situation that can destroy Kuafu, except for meteorites, which are gravitational vortices. It is clear from his subsequent research that gravitational vortices do not exist separately from gravitational winds, after all, they are huge forces that can bend space, and it is impossible to cause this phenomenon without corresponding energy and mass.

"Could it be the part of the damage that was damaged in the last gravitational wind crisis? Be...... Fatigue intensity! Jiqing thought of another possibility, metal alloy materials have a property called fatigue strength, and gravitational winds have a certain frequency, if the stress concentration at the outer shell of the Kuafu is repeated and reached a certain number of times, the micro-loss between the material molecules will reach the maximum. In this case, although the appearance of the material has not changed, its strength has been much lower than normal, and at a certain time, or under the trigger of a certain situation, it will break.

"There is also a probability of this, but even the fatigue strength test standard of general engineering metals is more than a million times, and the standard of the material of the Kuafu shell is more than 50 million times. The magnitude of the gravitational wind changes so that the internal stresses generated by the shell are sufficient, but the total period is far from the level of 10 million cycles. ”

"Then it could be a new cosmic phenomenon."

"It is possible that in the face of the universe, the knowledge and experience of human beings for thousands of years cannot even reach the level of beginners."

"Jiqing, the online command has been issued, please prepare!" Hachi suddenly prompted.

"Yes, in the reply, the accusation center, the Ministry of Information Jiqing is ready to go online and ready to go online at any time." Jiqing checked the fixture, adjusted the holographic eyes, and waited for the next instruction of the system.

Equipped with different types of robotic arms and devices, the maintenance robots from the inner and outer planes of the hull shell continue to converge towards the rupture, and they are lined up in an orderly line according to the planned emergency repair plan, just like a team to be reviewed. In order to prevent the gravity-free environment outside the ship, these machines firmly adsorb themselves on the shell through the electromagnetic suction device on the chassis, and the intelligent program calculates and adjusts the adsorption electromagnetic force in real time, which ensures the stability and firmness of the robot's operation, and will not produce too much contact friction because the magnetic force is too strong, which affects the running speed and waste of energy.

The routes traveled by these maintenance robots are inlaid in the hull shell of the ship by special materials, after all, the materials used for the magnetic adsorption device and the materials used in the hull shell are very different. The channels formed by these adsorption materials, after reasonable planning and layout, extend in all directions like spider webs throughout the hull.

Behind the robot carrying the mechanical arm, there is a flat car responsible for transportation, several standard repair components are fixed on the flat plate, and the robot inside uses the connection device reserved on the shell to first erect a group of beam rods with a certain arc at the rupture, and then assembles different splicing plates together like building blocks, and finally forms a shallow bottom bowl-like cover inside. Eventually, another spider-like robot climbed atop the protective shield and filled the joints around the hood with a special gel, as well as in the joints, which slowly expanded to the ground under the action of a catalyst, filling all the gaps and quickly hardening, re-separating the interior of the cabin from outer space.

The depressurized isolation area in the cabin began to be pressurized with nitrogen, and the spider-shaped small inspection robot continued to circulate around the cover, carefully detecting possible gas leaks, and sealing them with another colloid in time until the entire closed structure was normal.

When the internal robots completed the temporary closure, the external robots were not idle, and they carried out a comprehensive mapping of the cracked shell under the control of the integrated maintenance department. The maintenance department quickly formulated a maintenance plan according to the plan that had been planned. When the robot is cleaning and cutting the shell plate, the internal processing plant is processing and replacing the shell, and all the emergency repair work is being carried out in an orderly manner.

When the shell board is processed and installed, the internal temporary enclosure will be experimentally pressurized to test the quality of the shell board. After passing the specified cycle and number of repeated pressurization and pressure relief tests, the internal temporary enclosure will be removed, and the standard components used for emergency repair will be transported back to the emergency repair warehouse according to type, waiting for the next task.

Jiqing looked at the briefing and detailed materials on the rupture of the shell released by the General Staff Headquarters, which described all the details of the incident in great detail, and there were also a large number of various videos and high-definition pictures in the attached materials. Since these materials are open to all crew members and encourage everyone to brainstorm, every part of the text, every picture, and every video material has many discussions and messages left by the crew.

This way of openly boasting about every major event that acrosses the astronauts has been a long-standing tradition, mainly to gather the thoughts and opinions of all the crew, is an easy way for humanity to harness its collective intelligence. All the crew members of Kuafu were elites from all walks of life when they set off, and their intelligence and analytical way of thinking about problems could allow Kuafu to better solve all kinds of unknown aerospace problems in the first place. This method became even more important when Kuafu completely lost contact with the earth, and although Kuafu set up a special research institute, the wisdom of an individual or a small group of people has a certain limit and time.

All the discussions and feedback of the crew will be collected and sorted out by the General Staff, and the useful information will be discussed by a joint meeting of multiple departments, and finally a complete analysis of the incident will be completed and recorded in the logbook.

There is nothing new in the emergency repair process in the data, and Jiqing has simulated a similar process in the holographic system many times, which is a necessary course for crew training. What really caught his attention was a very small detail of the cracked shell, and the main reason for the sudden rupture of the shell, the small pitted dots that were very unevenly distributed, which were of different sizes and irregular shapes, some looked very deep, and some had only a shallow trace.

If you zoom in on the picture and look closely, the edges of these defective pitting spots are very neat, and there is no state of high-temperature dissolution and outward extrusion deformation, which is not at all like the traces left by the impact of high-energy particles in space. Curiously, from the perspective of the 3D modeled model of several fragments, the basic properties of the material, which should be continuous and almost homogeneous, have now become very uneven, as discontinuous and hollow as the moths have eroded. Moreover, most of them are fully enclosed spaces, which proves that the defects caused by the material are not caused by the impact of high-energy particles, but are close to the bubbles or irregular impurities left over from the processing and molding process of the material, that is, the shell is made of substandard materials.

This can happen in some low-end factories on the planet, but it is very problematic on the Kuafu. As the pinnacle of human scientific and technological products, the key project of all mankind, and the hope of all mankind to fly to the universe, the Kuafu gathers the high-quality resources and technologies of the entire earth, and all materials and equipment are installed on the Kuafu after many strict tests. Even the spare materials and parts in the tank were of the same standard, and such obvious defects simply could not have existed in the Kuafu plan.

And even if this piece of material inadvertently enters the supply system of the Kuafu Project, it will be discarded at the time of installation because the first appearance inspection is unqualified. It is unbelievable that this shell material that triggered the third-level alarm was installed on the Kuafu after so many links.

Jiqing stared carefully at these strangely shaped pockmarks, and suddenly thought of something, he took off his holographic glasses, summoned the image to his hand, and looked down at the mutilation found not long ago on the operating table, although none of the pockmarks on the high-definition image were the same, but the irregular strange shape, made Jiqing feel a kind of panic, which is the instinctive reaction of human beings when they encounter unknown things.

Ji Qing took the hologram and searched his cabin, and found three more defects, these small defects were like ghosts with teeth and claws, penetrating into his heart through his eyes, inspiring a kind of coldness that penetrated his body, and then suddenly spread to his whole body, scalp and even the tips of his hair.

Jiqing shivered a few times in a row, and the shaking of his muscles made his mind crawl out of the pit and start to move.

A trace of doubt flashed in his heart, "Little Eight, take a look at the comments and summarize the information related to the discovery of pockmarks similar to shell materials." ”

"Understood!"

Xiaoba quickly sorted out the information, enlarged the virtual screen in front of Jiqing, and all the messages in it were classified and summarized in detail, and listed several types of graphical representations.

"So far, 99 people have posted 119 pieces of relevant information, 77 of which contain video data, 21 of which are holographic images, and there are 203 defects in the preliminary statistics that are suspected to be the same as the shell, and the locations of the defects are all over the ship, and there is no regularity in the current situation."

"So little?" Jiqing looked at the information in his hand, and there were thousands of obvious defects on the surface of one of the shell fragments, most of which were very concentrated, causing the local strength of the shell material to be greatly weakened, and this crisis was produced under the action of a certain trigger condition.

In addition, in the public information, information management, equipment department has released some important information, in some faulty instruments and equipment found similar damage, is the direct cause of equipment failure. Similar damage has also been found in storage devices where data center information has been compromised. ”

Jiqing understands that this kind of destruction is not from the inside out like the norm, but very irregular, and some locations may have suffered a lot of damage even if there is no sign on the outside.

"In this case, such as the case on the shell, it is not a problem with the material of the building, but it may be a kind of ...... in the universe Phenomenon"

Jiqing didn't know how to describe the situation of the Kuafu Father, so he could only use it as a phenomenon.

"It should be," Hachi immediately understood Jiqing's representation, "I did a fuzzy search of the database, and I haven't found any similar material defect records so far, and there is no similar record of the Kuafu in the logbook, this phenomenon may have never been touched by humans." ”

In other words, we now have no theoretical basis and no way to prevent this spatial phenomenon. And...... "Jiqing thought of another, more important thing, "this situation is not just about the damage to the hull, but also ...... Crew. ”

Recently, some of the crew members have experienced abnormal physical conditions, which seem to be related to internal injuries and internal bleeding, which are also obviously caused by unknown cosmic phenomena. The damage to the hull and equipment can be repaired, but if the crew suffers such an unknown damage to the cranial nerves, spinal nerves, or vital arteries, it is a very fatal condition and cannot be prevented.

Thinking of this, Jiqing suddenly felt a lot of invisible dark spots surrounding him and passing through his body, making him feel a faint tingling sensation in some places. He reached out and pressed against a point of pain, and the ubiquitous dark spot made him breathe rapidly.

"What's the matter, Jiqing." Hachi noticed his unusual performance, turned up the original volume, and changed a sound frequency, which is the usual way of the intelligent assistant, adjusting the abnormal state of the crew with external stimuli according to different situations.

Jiqing came back to his senses and felt Hachi's voice drive away his hallucinations, he put down his hand and said to Hachi, "It's okay, I thought of some important situations, Hachi!" ”

"Yes!"

"Ready to report to me."
