A special reconnaissance ship quietly left the harbor of Jupiter and sailed into the infinite depths of the universe.

The special reconnaissance spacecraft is a small combat spacecraft, known for its fast speed, strong concealment, and can also fly faster than light in interstellar space. The small ship at the checkpoint takes two hours to reach the heavy transport ship, while the special reconnaissance spacecraft takes only fifty minutes to reach the heavy transport ship, although it departs from a base located within the star system.

In front of this heavy transport spacecraft, the small spacecraft of the special reconnaissance spacecraft and the checkpoint are like two small mosquitoes beside the elephant, but in this empty space, including this huge heavy transport spacecraft, there is not even a single mosquito, only boundless silence.

A radio wave emanated from the reconnaissance ship and entered the small ship.

"I'm Wang Hao, and I'm the head of the investigation team for the Nimbus spacecraft incident. Please turn on the spacecraft interface and our reconnaissance ship will dock with the Nimbus spacecraft. ”

The small ship was quick to respond: "Okay, please wait. Well...... Something incredible may have happened inside the spaceship, and there may be a certain amount of danger. For safety reasons, we recommend that a robot inspect it instead of you. ”

The reconnaissance ship was silent for a moment, and responded: "We have enough knowledge of its danger and have fully demonstrated the necessity of this operation. You don't have to worry about that. ”

"Since you insist, then feel free." The small ship replied.

With the issuance of several messages, the docking port of the Nimbus spacecraft opened, and the special reconnaissance spacecraft that Wang Hao was riding docked with it.

Standing in front of the hatch, Wang Hao took a deep breath, turned his head to look at the members of the action team behind him, who were also wearing full-body isolation suits, and said in a solemn and slow voice: "You still have a chance to regret it now." ”

The players were silent. Wang Hao continued: "There may be some unknown risk factor in the Nimbus spacecraft, which may cause our death or disease. Also, for security reasons, once inside the Nimbus ship, we must all be quarantined and unable to make contact with anyone else until the incident is investigated. If the incident is not investigated, we will be quarantined for the rest of our lives. ”

The team remained silent. Wang Hao smiled slightly: "In that case, let's go." ”

Wang Hao pressed a button, and the hatch in front of him slowly opened, revealing the interior of the Nimbus spacecraft in front of Wang Hao.

As an infectious disease expert and microbiology expert, Wang Hao does not know how many times he has seen festering and distorted human bodies in research and clinical practice, Wang Hao has always thought that his mind has been honed to the point that he cannot be shaken, but after really seeing the scene inside the Nimbus spacecraft, Wang Hao still feels shocked.

At this moment, Wang Hao felt like he had come to hell.

The first thing that caught Wang Hao's eyes was the number of more than 30 corpses. The bodies were placed in different positions, but it was clear that they had all endured great pain before they died. Their expressions were hideous and distorted, and their bodies were twisted at all sorts of uncanny angles. Illuminated by pale yellow light, it looks like a death pavilion.

If this is the case, it is not enough to shock Wang Hao. What really shocked Wang Hao was that he found that these dead astronauts ...... The vast majority are suicides.

More than thirty well-trained, experienced, and mentally resilient astronauts died here. They did not die of disease, they did not die of a cosmic catastrophe, they did not die of a sudden malfunction, but they died of suicide.

"The temperature here is minus 158 degrees, so their bodies are still very well preserved." One of the team members said in the communication channel.

Wang Hao nodded slightly, shook off the emotional fluctuations in his mind, and began to examine these corpses from the perspective of a medical expert.

More than ten meters to the left of Wang Hao lay a corpse. The corpse's forehead had sunken, and there was something in the depression that I didn't know if it was blood or brains - of course, they had all been frozen solid. There was also some splashing liquid residue on the walls, like blood, but it was all blackened.

Wang Hao observed carefully, and in a moment, there was already a conclusion in his mind.

"There was no sign of violence on its body, and it couldn't have been pushed by the rest of the people pushing it against the wall with its forehead. Then there is only one possibility, that is, when he was still alive, he hit his forehead like this, and then died. Wang Hao said slowly, feeling a little cold in his heart.

Wang Hao didn't know how ruthless a person had to be to end his life in this way, Wang Hao only knew one thing, this astronaut must be very eager to die before he died. He must have slammed into the wall with all the force he could in his life, as if there was a flame there, and he was a moth.

Another astronaut stuck a fork into his chest and caused his own death. Wang Hao, who is also involved in forensic science, can clearly see that the process of the fork entering the human body is not smooth, and the astronaut must have made great efforts to make the fork touch his heart and take his life through continuous rotation and cutting.

Another astronaut stabbed a steel tube into his mouth and through the back of his head; Another astronaut stabbed a pen into his temple.

"Are they all crazy? Why did they end their lives by such cruel means? Wang Hao kept asking in his heart, but he couldn't find an answer.

In the continuous observation, Wang Hao made another discovery.

These astronauts all seem to have developed some kind of disease before they died. Wang Hao saw that there were large areas of ulceration on the naked limbs of those astronauts. In some places, the ulceration is so severe that even the bones can be faintly seen.

Arms, head, legs, chest and abdomen...... All of them.

Due to the extremely low temperatures, the ulcers have been frozen to the same blue-black color as normal skin, with a layer of frost attached to them, and they are impossible to see unless you look closely.

This discovery moved Wang Hao's heart: "I don't know if these ulcers were formed before death, or after death?" If it's before death, then ...... What could be the reason for this? Are these astronauts so desperate to end their lives because of this unknown disease in search of relief? ”

Until the specific test results come out, Wang Hao is not sure of this for the time being. After observing for a while, Wang Hao carefully took out some sample bags, trying to remove some samples from the festering parts of those dead astronauts, but the extremely low temperature made the process difficult, these frozen corpses were as hard and brittle as glass, ordinary sample collectors were not useful at all, and finally the samples were successfully removed by the laser knives carried by the team members.

The accompanying staff also carefully took photos and video records without destroying the scene, and it took nearly an hour to observe the place.

After collecting the information here, Wang Hao led the entourage into the next cabin. This chamber seems to be a place for astronauts to exercise and have fun. It's a lot more normal here, just a little dilapidated, but there's nothing else.

The next few cabins were like this, and there was nothing of value for Wang Hao to see.

Turning on the portable computer and looking at the spaceship map handed over to him by the industrial department, Wang Hao thought for a while, and then said: "Electronic reconnaissance team, follow me to the main control room of the spaceship, get all the records of the spacecraft, and the rest of the members continue to search the spaceship, and report to me as soon as they find anything." ”

"Yes!" The entourage agreed in unison.

The members of the investigation team immediately divided into two teams, one team followed Wang Hao directly to the main control room of the spacecraft, and the other team dispersed and began to search the spacecraft as a whole.

The Nimbus is a heavy transport ship with thousands of different compartments inside the hull and tens of thousands of labyrinthine passages to and fro. If it weren't for the guidance of a map, or someone who was extremely familiar with the internal structure of the spaceship to lead the way, Wang Hao would easily get lost here.

Walk through the long, dark corridors, through one heavy hatch after another, through the cabins of different uses...... Wang Hao's thoughts were enveloped by a strange feeling.

This spaceship, which belongs to human civilization and shows the characteristics of human civilization everywhere, brings strangeness and weirdness to Wang Hao and his teammates at this moment.

The members of the electronic reconnaissance team following behind them silently grabbed the energy guns in their hands and made a vigilant move, as if some monster would jump out of front at any time.

Of course, the monster did not appear, and Wang Hao also walked smoothly to the general control room of the Nimbus spaceship. After opening the general control room with a special password, Wang Hao finally made a new discovery.

Wang Hao saw a corpse again, and the corpse was slumped on the chair in front of the console, leaning back, arms drooping, the same as the rest of the corpses, this corpse had already been frozen and stiffened by the extremely low temperature.

Across from the corpse was a working display. On that screen, what appeared to be a snippet of a little girl's life was playing.

It seems to be a playground. The little girl, led by another young woman, is experiencing a variety of rides. The little girl kept laughing, obviously happy, but the audio playback equipment seemed to be broken, so no sound came out.
