On the early morning of the sixth day, Wu Chen woke up on time.

The gravity is restored without any sense of influence, and the watch physical examination is completed. Everything inside and outside the "Mobile Shelter" is normal.

The superhydrophobic surface of the nanocomposite armor microstructure assists the ion-rich polymer coating anti-freeze material, leaving only snow on the surface of the "T815 Extreme War Truck" without being frozen at all. This also reflects the meaning of "extreme". Under extreme conditions, it can still maintain normal functions.

"Do you sleep well, Dust?" Ferosa smiled and greeted.

"Excellent." When Wu Chen walked out of the capsule, the beautiful female soldiers had already prepared breakfast.

"Life Cabin" restaurant.

As soon as Wu Chen sat down, he saw that the atmosphere was a little solemn: "What's wrong?"

"Last night, I contacted the survivor." The Valkyrie who had not been sleeping all night was still in good spirits.

"What then?" Wu Chen could have looked at the multi-function watch directly, but he still wanted to hear the Valkyrie say it in person.

"Then he told me about the 'Gate of Hell'..." After a slight pause, the Valkyrie stared at Wu Chen: "'Kora Deep Hole'."

Speaking of the weird legend of "Kola Superdeep Borehole", many big players have heard of it. It began with the "Deep Sea Drilling Plan" proposed by the United States in the 1960s. At that time, the Cold War proposed two plans to explore the universe upward and downward, which is "the plan of human beings entering space and landing on the moon". Looking at what is in the sky, obviously, drilling holes into the center of the earth and seeing what is inside the earth. In order to reach the interface between the crust and the mantle before the American drilling project, it is: "Moholovich Discontinuous Surface (referred to as the Moho Face)".

The term "Mohole" is composed of "Mohorovicic (Croatian scientist who first discovered the interface between the earth's crust and mantle and named it" and "hole, drilling hole, drilling (hole)", which means "Moho drilling" and "ultra-deep drilling".

At that time, there was another saying: it was far more difficult for humans to explore under their feet than above their heads. Humans could already reach the edge of the solar system, but it was difficult to drill a deep well more than three thousand meters deep. Therefore, in the 1970s, the former Soviet Union carried out a huge scientific deep drilling project on the Kola Peninsula near Norway: "Russian Mohole". There are records that the drilling hole is 12,262 meters underground, which was the record of reaching the deepest part of the earth at that time.

Exploration began on May 24, 1970 and was directly led by the former Soviet Minister of Geology. By 1983, the drilling depth of the well had reached 12,000 meters, and the last 262 meters was carried out between 1983 and 1993, which took a full 10 years.

The project was then terminated for some reason, and the official reason was that the funding was insufficient. But I don’t know when the statement that the project had opened the door to hell began to spread. Some so-called exploration technicians appeared and claimed that "a demon came out from the ground."

The reason for the paranormal phenomenon seems to arouse people's curiosity more than "insufficient funding". Just as they were about to go deeper, something strange and terrifying happened. First, the drill bit was often damaged for no reason, and then the bottom of the drilling well always heard a terrifying roar. Some people said it seemed like the sound of hell, but in desperation, they had to stop this experiment.

One of the materials edited by Feiye's "Limited Planning: A Doomsday Walk" comes from the plot fragments and time and space adapted from these strange legends: "Kola Superdeep".

The whole story of "Kora Deep Hole" happens similar to that supernatural legend. A strange sound was heard while drilling in the former Soviet Union. An accident occurred in the laboratory deep in the ground, so the government began to organize rescue work.

Anya is a microbiology research expert. Her boss asked her to enter the underground laboratory to take some samples from the victims for subsequent research. So, under the leadership of this boss, the heroine and a team of fully armed soldiers went to the Kora Peninsula.

When they arrived at the laboratory at the bottom of the cave, the heroine and her party found that there were still a few staff members who were still not able to withdraw.

As a scientific researcher, the heroine stayed in the laboratory to ask the staff about the incident and tried to take some samples. Several soldiers were ordered to go down to the bottom to see if there were still people stranded. Soon the heroine discovered a severely infected female researcher Olga. The woman was in a trance and had some changes in her body. Her back was infected and her whole body lost pain. After sampling and research, it was found that this was an ancient virus that was resistant to high temperatures. It was released because of the depth of the drilling hole. This fungus was used as the culture medium and reproduced extremely quickly and could even control human activities. As long as the soldiers descended deeper into the ground, they were killed by these fungi. Then the fungus quickly infected the entire laboratory. As long as humans were infected, they would become a twisted "paste" for dozens of minutes.

During the study, the surviving woman attacked the female doctor, and then the two turned into moldy spores that made people's scalp tingling. Moreover, the moldy spores actually exploded and released toxic gases. The team leader was unfortunately infected. When he went to join the team calling on the radio, he saw a strange monster composed of human incomplete limbs and mold, which could also eat people and merge into his body! Fortunately, the monster was always in the high temperature and was afraid of low temperatures, which gave Anya a glimmer of life. However, Anya was still inhaling the virus while running away and was infected. Anna understood that if this deadly virus was really brought to the surface and transmitted to others, it would undoubtedly be a catastrophe for humans...

The derivative plot in which Wu Chen is located is the subsequent catastrophe - the "world-killing disaster".

Ancient mold viruses overflowed from the deep hole of Kola and spread rapidly throughout Europe, and then spread to Africa, Asia, and America. Within several years, they infected the entire earth.

After the catastrophe, the world immediately established a coalition government to deal with the crisis of all mankind. However, all efforts ended in failure. As one of the crisis response mechanisms, at the beginning of the catastrophe, many human elites were sent to space and expanded the ISS International Space Station as much as possible.

Become the last space shelter for all mankind.

The person who contacted Valkyrie last night was the left-behind staff of the ISS International Space Station.

"Left-behind personnel?" Wu Chen keenly grasped the key elements of this derivative plot: "Can it be that most of the surviving humans on the ISS International Space Station have moved to alien planets?"

This is the most common science fiction plot. Of course, just as the beginning of the Age of Interstellar Discovery, it is often due to a disaster in the end. This is also the direction of the derivative plot that players are familiar with.

"That's right, not right. Sir." Valkyrie replied calmly: "They did move out of the ISS International Space Station, but did not go to the alien planet. Instead, they went to an asteroid."
