On the tenth day of the F-1 landing, the expedition led by Femmon had set up a solid camp at the landing site, and the three medium-sized buildings had been half completed, which were three buildings composed of prefabricated composite metal materials, each with ten floors, three of which could provide the work and living needs of tens of thousands of people, and the final results of sampling the ice on the surface of F-1 were not satisfactory, because the sampling of the landing site and nearby showed that the water here was not ordinary water, but heavy water and semi-heavy water, This meant that it was a frustration to go through a complicated process to obtain ordinary water that could be used for daily drinking, but Faimon reassured everyone that it was not a big problem, and although he hoped to find ordinary water, he could not act anxious.

Professor Gu Liang was very pleased with this discovery, because the antimatter fuel cell technology now used by the New New Human Association uses heavy water as an intermediate substance, which can undoubtedly save a lot of costs in energy production, and he believes that although heavy water cannot be directly drunk, the treatment process is not complicated, so he suggested that the 'group of five' pass an urgent motion to establish a large-scale anti-heavy water plant to start mass production of ordinary water, and it was quickly approved.

On the evening of the sixteenth day, the expected danger still happened, two giant creatures 'Big Fat Worm' somehow crossed the huge natural ice trench and actually reached the vicinity of the camp, and the temporary safety warning net played a role, and the release of tens of thousands of volts of high-voltage electricity stunned the 'Big Fat Worm'. These security warning nets are set up at intervals of 100 meters with antimatter energy batteries as the energy of the invisible power grid, a total of three, each one kilometer apart, two giant creatures one after the other, the result is equivalent to breaking through the two defense lines, if there are four such giant creatures rushing forward, then one will definitely rush into the camp, the consequences will be unimaginable.

Therefore, Fei Meng ordered Gu Xinyu to begin to strengthen the vigilance in the air on the ground, expand the scope and density of the vigilance, and strictly prevent the appearance of fish that slipped through the net again. After biologists went to the scene to study this giant creature, it was found that this creature has a very thick keratinized shell, the thickest back, its brain is very simple, although the size is large and the intelligence is only equivalent to the intelligence level of an ant on the earth, but it is very sensitive to smells, the body is very robust, and most of the liquid tissues in the body are composed of heavy water, which shows that they can drink or eat heavy water for a long time, and get energy from it.

While the scientists continued to analyze and research, Feimon was already organizing several small expeditions, who would use hummingbird transport planes as tools to start searching for other creatures and water sources outside the camp under the protection of hummingbird fighters, including land without heavy water and ice, and to explore more detailed topographic data, Feimon wanted to fully understand the details of the F-1 as soon as possible, and ordered five small expeditions of 100 people to set off together a day later to investigate and explore in five different directions.

While the expedition was searching, scientists were studying the climate, atmospheric composition, giant creatures and other items in more detail, and the situation of F-1 was showing more and more detail, and biologists were very interested in the big fat worm and studied it very carefully.

They found that the head of the big fat insect looks a little like a pig, has a large organ that looks like a nose, but only has a small eye on the upper part of the head, which may be because the reflection of sunlight and ice makes them minimize light intake, the mouth is very large, the teeth are very dense and sharp, the meat cannot be eaten because of heavy water, but it is very delicate, the body fluids and internal organs are basically white, it is difficult to distinguish the various organs, and most of its more than 3,000-ton body weight is concentrated on its bloated torso, The carapace on its back is many times harder than that of a tortoise on earth, it has no hair on its body but its skin is thick, it has a total of ten short legs that are short and strong, and there is also a thick cuticle on the soles of its feet and four sharp claws, which is the main reason why it can slide quickly on the ice, and the study of the residue of their stomach has found that they prey on their own kind, probably social animals, and obtain high-calorie food by attacking other groups.

Dong Ruijie's research has also made new discoveries, through drilling the ice, and then the study of heavy water ice Dong Ruijie found that the ice here is melting, frozen many times, basically every five years, which coincides with the original elliptical orbit of the F-1, every time the glacier melts at perihelion, and when it is far away, it freezes again with the drop in temperature, and the cycle repeats.

Three days later, the northern exploration team sent back a good news to the base, they found an area similar to a group of karst caves more than 5,000 kilometers away, there are many caves leading to the underground in this area, because the glacier cover is difficult to find in the air, after considering Feimeng agreed to their plan to enter these caves for investigation, and immediately sent an additional support detachment of 500 people in this direction, Gu Xinyu volunteered to lead this support detachment after Feimeng's consent, Twenty Hummingbird A-300 fighters and five Hummingbird transport planes with large exploration equipment and equipment marched towards this cave group.

The previously arrived exploration team waited until Gu Xinyu's support detachment arrived and converged, Gu Xinyu sent several hummingbird fighters to carefully inspect the newly discovered large karst cave group, and found that this area is very large, with a radius of thousands of square kilometers, and there is a big hole every few kilometers, some of the holes are in a flat place, so the holes are directly facing the sky, and some of the holes are inclined along the uneven terrain, Gu Xinyu decided to divide the exploration team into five teams, he chose the five largest holes, and then ordered to act separately, Head to the interior of the cavern.

After three days of careful investigation, the Gu Xinyu expedition team found that the inside of these caves are connected to each other, very deep, and there are many huge independent circular caves in them. Big Fat Worm's nest, it turns out that these animals may live underground, because the Crystal Angel moved the F-1 terrestrial planet to change the climate, these large animals that originally lived underground migrated to the ground that is already suitable for life, so these large caves are left, the interior is very smooth and the space is huge.

After reporting the exploration situation to Fei Meng, Fei Meng and many experts also checked the data sent back by Gu Xinyu, and many people thought that this discovery was very important, because the exploration teams in all directions have found many such cave groups, and also found that there are large liquid water bodies deep under the flat heavy water ice surface, although it is also heavy water, but the area is larger than the Pacific Ocean on the earth, and there is a lot of room for development in the future. The team of five finally decided to establish several large semi-underground bases in the cavern area and establish themselves before starting development with the rest of the F-1 world.

After the target was determined, the 0555 Dreadnought, which had returned to a low-space orbit of 10,000 kilometers, returned to the ground, suspended in the air at 300 meters above the determined cave area, and a large number of infrastructure personnel and engineering equipment began to officially land, and Feimont also ordered his daughter's No. 3 space city in charge of the temporary camp to begin to separate fifty Dreadnoughts, and gathered more construction engineers and construction robots and other equipment and materials to prepare for a large-scale landing in the cave area of F-1 for engineering construction.

At the same time, the Space City Consortium also descended in altitude according to the plan, from 800,000 kilometers of far space orbit to 300,000 kilometers of orbit, as if the third moon rose in the sky of F-1, and then 50 Dreadnoughts loaded with materials and construction personnel successively broke away from the No. 3 Space City Consortium and entered the cave area under construction, and large-scale base construction began.

With the smooth progress of the work, more than two months later, Fei Meng remembered Qian Zhennan again, he found Qian Zhennan who was busy filming at the construction site again, Qian Zhennan naturally understood Fei Meng's purpose of looking for him, and soon agreed to Fei Meng to return to the space city to accept the operation arranged by Professor Li Sucai, Professor Li Sucai has already told Fei Meng that it only takes five surgeries to completely cure Qian Zhennan's physical defects, and Qian Zhennan will be able to completely return to normal life after three months.

Qian Zhennan returned to the No. 1 Space City, and handed over the shooting work to several of his assistants, Chen Fangyu had been notified by Feimeng, and also came to the No. 1 Space City from the No. 2 Space City, and personally greeted Qian Zhennan who returned from the ground, when Qian Zhennan saw Chen Fangyu who came up to greet him on the tarmac, he stood on the gangway of the hummingbird transport plane Qian Zhennan's eyes were in tears, he grew so big This is the longest time he has left Chen Fangyu, he has been accompanied day and night before, and the relationship is like a mother and son, Qian Zhennan immediately ran to Chen Fangyu, opened his strong arms and hugged Chen Fangyu in his arms, Chen Fangyu of course knew that Qian Zhennan missed her very much, although she was a little about to suffocate, but she did not struggle, and gently comforted Qian Zhennan and said: "Okay Xiao Nan, okay, everything will be fine soon, I will accompany you directly to see Professor Li Sucai, and you will completely recover after the operation, I have already found a good girl, I hope you get married as soon as possible, and many problems will be solved at that time." ”

Three minutes later, Qian Zhennan finally let go of Chen Fangyu, seeing Chen Fangyu holding his hands on his chest and panting hard, he smiled a little embarrassedly and said, "I'm sorry teacher, I miss you so much, what did you just say?" Have you already found me a wife? Who? Do I know each other? Are people willing? ”

Chen Fangyu took two breaths and finally calmed down, she said with a smile: "You know, she is a girl from the Super Energy Research Institute, and now she is doing things with Chen Min, I know that she has always admired you, but the girl's family won't say it herself." ”

"Teacher, are you going to read other people's minds, otherwise you wouldn't know so much?"

Chen Fangyu didn't answer with a smile on her face, but just took Qian Zhennan's big hand and said, "Let's go, Xiao Nan, don't let Professor Li wait, her medical team is already waiting for you." ”
