In 2022, a nuclear war broke out on Earth, which lasted for about a year. As a result of the excessive use of nuclear weapons, the Earth's structure has become unstable, with frequent earthquakes and volcanoes. Not only have extinct volcanoes erupted around the world, but countless new volcanoes have also emerged, and much of the Earth's surface is shrouded in the shadow of ash clouds. 2025, the third year after the nuclear war. After three years of self-repair, the frequency of earthquakes and volcanic eruptions has been greatly reduced, and volcanic ash clouds no longer rule the sky.

On the earth's arctic ice, there is a large scientific research base with a length and width of 500 meters, and a five-star red flag flutters high in the square in the center of the base. If you look down from the sky, you can see that there are four huge Chinese characters in the square, the ice dragon base. The entire base is composed of new synthetic materials, which not only have high strength and toughness, but also have a specific gravity much less than water. The base is a modular combination that sits on the ice and is held in place by ten massive anchors.

This is China's third scientific research base in the Arctic and the largest in the world.

Zhang Le, who woke up from his deep sleep, saw the pale blue sky through the transparent roof. The polar day has finally arrived. Due to the latitude, the rays of the polar sun are very weak, but fortunately there is a huge sunlight collector at the base, with 6 arc-shaped mirrors forming strange angles, and through a mast towering high, reflecting the sunlight to all corners of the base.

The polar night days are too boring, and the energy at the base is not only not enough to provide basic lighting, let alone the energy consumed to use electronics. Most of the base support personnel have little entertainment other than eating and bragging. As an agricultural expert, the only thing Zhang Le can do in the polar night environment is to cultivate mushrooms.

After moving his body, Zhang Le entered the bathroom. This is a makeshift dormitory in the growing area, sharing a roof with the mushroom house, which is separated by a transparent glass wall, with only a bed and a simple bathroom. The reason why Zhang Le likes to stay here is because there is a light here. For bases that lack energy, places with lights are important places. On the polar night days, mushrooms are a very popular delicacy for the Ice Dragon base, which lacks fresh vegetables. Mushrooms need a glimmer to grow, so there's a light here.

The Ice Dragon base has three main power generation facilities: one is solar panels all over the base; the second is 12 windmills; The third is a deep-sea geothermal power station. In 2023, the site experienced a major tsunami, which damaged 11 of the 12 windmills and leaked the steam boilers of the deep-sea geothermal power plant.

During the polar night, only that windmill can still provide electricity. Wind power is dependent on the weather and is extremely unstable, so we can only save energy as much as possible.

The temperature of the room is around minus 10 degrees Celsius, and although the geothermal system cannot be used to generate electricity, its water circulation system can also be used for bathing and heating.

When the polar day came, Zhang Le's mood became happy. He sang the bath song loudly and washed himself beautifully.

Drying himself, Zhang Le walked out of the bathroom with a grin. As soon as the door opened, he was startled and quickly covered himself with both hands.

Standing diagonally in the room was a tall beautiful woman wearing a beige tweed trench coat, a long purple scarf, lazy long curly hair, a somewhat round face but a pointed chin, sharp eyes, a hint of masculinity in the softness, and a pair of big black-framed glasses, which made her skin as white as snow.

The tall beauty is the director of the Life Science Department of the Ice Dragon Base, one of the three powerful figures in the scientific research station, a double doctor in clinical medicine and genetic science, and the leader of three national key scientific research projects, named Zhao Fei, 28 years old. Zhang Le is just a grassroots agricultural expert in the Ministry of Natural Sciences, a 25-year-old double-degree undergraduate student at China Agricultural University.

Zhang Le asked strangely while clutching his underneath, "Dr. Zhao, why are you here?" ”

Zhao Fei put his hands in the pockets of his windbreaker, his eyes were like torches, and the roots of his black and red-soled high-heeled shoes hit the floor with a "bang".

Zhang Le, as a low-level employee who is messing around, has not spoken a few words to Zhao Fei, even if there are only 10 people left in the base, there are still only a handful of words spoken by two people. Zhao Fei is doing research except for eating and sleeping, and has nothing to do with him.

Zhao Fei glared at the bottom that was tightly covered by Zhang Le, pursed the corners of her mouth disdainfully, and snorted: "Don't be awkward, hurry up and put on your clothes and follow me, how can you look like a woman." After a pause, she continued: "I'm studying medicine, so there's nothing to cover. After saying that, he turned around and went out first.

Those who study medicine are really perverts, and the human body has no secrets about them.

Zhao Fei is currently the top leader of the base, and he must be looking for Zhang Le because he has something to say, thinking of this, he hurriedly got dressed and walked out quickly.

Seeing him come out, Zhao Fei turned around and left, and Zhang Le followed Zhao Fei suspiciously.

Walk through the planting area, past the locker room, walk through the corner of the canteen, and come to the base of Ice Dragon Square. There was a red sun on the horizon, the sky was blue, there was not a trace of clouds, and the cold wind blew, and Zhang Le shrank back.

Zhao Fei walked to the center of the square of the Ice Dragon Base, and then stopped, with a huge sunlight collector above his head.

Zhao Fei didn't sell it, looked at Zhang Le, who was a little cramped, and asked, "I heard Zha Xiaoxia say that you are going to return to China, aren't you?" ”

Zha Xiaoxia is an employee of the logistics department of the base, a graduate of the University of Science and Technology of China majoring in geophysics, and is a good "buddy" of Zhang Le, and Zhang Le is the same post-00s.

Zhang Le nodded, although he knew that returning to China was in danger, he still decided to go back. Although her mother didn't give her much love after the divorce, her father was nowhere to be seen. But the hesitation of the last days made Zhang Le let go of his knot and began to miss his parents.

After the end of the nuclear war, the personnel of the Ice Dragon Base returned to China in several batches, but so far there has been no feedback back, and Zhang Le knows the danger.

Zhao Fei was silent for a while and said, "Okay, since you want to go back, let's go back, and call Xiaoxia to my laboratory in the evening." After saying that, he turned around and left. Zhang Leleng was stunned for a while, and he didn't know which one Director Zhao was singing.

Zhang Le looked at his watch, the time was three o'clock in the afternoon, although he was a little hungry, but the time for the canteen to start eating had not yet arrived, so he could only find something to eat by himself. This is difficult for him, an agricultural expert, and the entire planting area is his own territory.

Zhang Le remembered Xu Lang's laboratory. Xu Lang is a 33-year-old expert in new materials and energy, very handsome, straightforward, not hesitant to guide newcomers in the workplace, is the first life coach he met after graduation. Three months ago, Xu Lang and the last group of evacuees returned to China, and before leaving, he gave Zhang Le the key to the surge power laboratory.

The surge power generation is experimental in nature, the output equipment is a small artificial sun, and the laboratory is located in the southeast corner of the planting area, with an area of more than 100 square meters. With an artificial sun, you can grow vegetables in the polar night environment, although this artificial sun is not very powerful, but it is enough for Zhang Le, so he planted vegetables in the laboratory.

A few months have passed, and Zhang Le didn't want to go over to see the growth of vegetables, but in his heart, as long as he didn't go to that laboratory, he felt that the amiable Xu Lang was still there and did not return to China.

He decided to go to Zha Xiaoxia first, and then go to the laboratory together, and share good things with his buddies.

The dormitories at the Ice Dragon base are divided into men's and women's quarters, except for couples and supervisors who can be assigned to a separate dormitory, and the rest of the single employees are two-person rooms.

At present, there are only three women in the base, Zhao Fei, Zha Xiaoxia, and Zhuge Chen from the base security department. Zhuge Chen and Zha Xiaoxia live in the same room.
