Hungover, I crossed over to the psychic realm

Lin Yu and Li Qiang stood at the entrance of the time-space passage. The wind howled past them, kicking up dust and gravel on the ground, as if playing a unique melody for their departure. Behind them was the vast interstellar world full of unknowns and adventures. Among the distant stars, there was the burning blood they had shed, with each drop carrying their perseverance and fearlessness in exploration; there was the life-and-death friendship forged when they fought side by side, and those moments of supporting each other on the verge of life and death had already been deeply engraved in the depths of each other's souls; and there were countless unforgettable experiences, some thrilling and exciting, some warm and touching, all weaving together to form their magnificent interstellar adventure epic.

Lin Yu squinted his eyes slightly, his gaze transcending time and space, as if he could see again the scene of their fierce confrontation with alien creatures on that planet full of mysterious energy. The light of laser weapons flickered, and the explosions were deafening. Every dodge of an attack and every counterattack was a challenge to the limits of life. Li Qiang, on the other hand, clenched his fists, and in his mind emerged the picture of everyone sitting together on the interstellar spaceship, sharing limited resources and discussing the next destination together. At that time, although they faced many unknowns and dangers, their beliefs in their hearts were extremely firm.

However, at this moment, what filled their hearts more was the longing for Earth. Earth was their root, the place they always yearned to return to no matter how far they had traveled. There were their relatives, the familiar mountains, rivers, cities, streets, and every bit of their growth memories. During the days of wandering in the interstellar space, everything about Earth was like a warm light, illuminating their way forward and giving them the strength to persevere.

Taking a deep breath, the two looked at each other, and a trace of determination flashed in their eyes. They resolutely stepped into the time-space passage. In an instant, a powerful force that was almost suffocating wrapped them tightly. This force was like thousands of steel needles stabbing into their bodies, and every inch of their skin felt a strong stinging pain. Everything around them seemed to be drawn into a huge whirlpool, and the scene became blurry. Colors and lights and shadows intertwined, forming a strange and shocking visual effect. The concepts of time and space became blurred at this moment, and they seemed to be in a chaotic world without front, back, left, or right, without past or future.

Their bodies endured great pressure. Every inch of skin and every bone protested in pain under the impact of this force, as if they were about to be torn apart. Lin Yu felt as if his body was being put in a huge juicer, and his internal organs were being constantly squeezed and distorted. Li Qiang gritted his teeth, and big beads of sweat rolled down his forehead. The veins on his arms bulged, and every muscle was tense as he tried to resist this powerful force.

During this long and torturous journey through the time-space passage, Lin Yu and Li Qiang could only hold on with their firm will. The appearance of Earth, the smiling faces of their relatives, and those once ordinary but extremely precious fragments of life kept emerging in their minds, becoming the driving force for them to persevere. Lin Yu remembered that when he was a child, in the hot summer, his father took him fishing by the river. The sunlight shone on the water, glistening. His father patiently taught him how to cast the rod and how to watch the float. Li Qiang recalled the figure of his mother busying in the kitchen. The familiar smell of the food could always dispel his fatigue of the whole day the moment he got home from school.

I don't know how long it had passed, it seemed as long as a century, yet also as if it was just an instant. Suddenly, a bright light flashed before their eyes. The dazzling light made them close their eyes subconsciously, and then, the feeling of standing on solid ground came. They slowly opened their eyes and looked around. The familiar atmosphere rushed towards them, and they knew that they had finally returned to Earth and were standing on the streets of the city they had once been so familiar with.

However, the scene in front of them made them feel a bit strange. The buildings in the city had become more modern and high-tech. The once familiar high-rise buildings had been replaced by uniquely shaped buildings full of a sense of the future. The appearance of these buildings seemed to be a fusion of flowing metal and transparent crystal, shining with a strange light under the sunlight. There were also flowing lights and shadows on the surface of the buildings from time to time. Upon closer inspection, it turned out to be the real-time display of various information, including news, traffic conditions, and even advertisements for some technological products they had never seen before. The images in those advertisements were vivid, as if they were brought into a brand new world.

The streets were bustling with traffic. The vehicles driving on the streets were no longer traditional fuel cars but new types of transportation that hovered in the air. These vehicles had smooth shapes, extremely fast speeds, and made almost no noise. Occasionally, a vehicle would speed by, leaving only a faint light and shadow. People's clothing had also changed a lot, no longer the common styles in their memories. People's clothes were lighter, more form-fitting, and the colors were more vivid and eye-catching. Moreover, many people's clothes were equipped with various small intelligent devices. Some could display the time and weather in real time, and some could interact with the surrounding environment, as if these clothes themselves were a small intelligent terminal.

Lin Yu and Li Qiang looked at each other, feeling both excited and a bit confused. They were excited to finally be back on the Earth they had been longing for, but they were confused because so many things had happened on Earth during the years they were away. This familiar yet strange world made them feel at a loss for a moment. They didn't know how to reintegrate into this world that had undergone earth-shaking changes, nor did they know if their former relatives and friends were still there, and if they had also changed as much as the world.

Lin Yu looked at everything in front of him, filled with mixed emotions. He remembered every bit of his childhood in this city. Those days of playing with his little friends seemed like it was just yesterday. They chased and frolicked in the alleys, flew kites in the park, and shared their little secrets under the old tree. He turned to look at Li Qiang and found that Li Qiang was also immersed in memories. "We're back, but it feels like everything is different." Lin Yu said softly, his voice tinged with a trace of helplessness and emotion. Li Qiang nodded, "Yeah, I wonder what Earth has gone through during the years we were away."

They strolled on the street, trying to find some familiar traces. Passing by a coffee shop they used to frequent, they found that it had become a high-tech experience store. The store displayed all kinds of novel technological products, such as a helmet that could achieve a virtual reality immersive experience. Once you put it on, you could instantly be in a completely virtual world, whether it was an ancient castle or a mysterious underwater world, you could feel like you were really there; there were intelligent robots that could be controlled according to people's thoughts, which could understand people's ideas and complete various tasks according to people's wishes; and there were medical devices that could cure all kinds of difficult and complicated diseases. These devices used the most advanced genetic technology and nanotechnology, making it possible to cure many diseases that were once considered incurable. These products broadened their horizons and also made them deeply feel the rapid development of Earth's science and technology.

As they walked, they came to the community where they used to live. The gate of the community had been replaced with a smart recognition system, and only the residents of the community 

could enter through facial recognition. Lin Yu and Li Qiang stood at the gate, a bit hesitant. They didn't know if their families still lived here, nor did they know how to explain their identities to the community management personnel. Just as they were hesitating, a familiar figure came out of the community. Lin Yu took a closer look and was surprised to find that it was his father. His eyes instantly filled with tears, and he shouted loudly, "Dad!"

Hearing the voice, Father Lin turned around. Seeing Lin Yu and Li Qiang, a look of shock and surprise appeared on his face. "Xiaoyu, is it really you? You're finally back!" Father Lin walked quickly over and hugged Lin Yu tightly. Lin Yu felt the warmth of his father's embrace, and much of the confusion and uneasiness in his heart dissipated instantly. He knew that no matter how the world changed, home would always be the warmest haven.

Led by Father Lin, Lin Yu and Li Qiang returned home. The layout of the house had also changed a lot. Various intelligent devices made life more convenient. The lights would automatically adjust the brightness and color according to people's moods and the environment, the curtains would open and close automatically at sunrise and sunset, and the intelligent kitchen utensils in the kitchen could automatically cook delicious dishes according to the recipes. Lin Yu sat around with his family and listened to them talk about what had happened on Earth during these years.

It turned out that during the years they were away, Earth had experienced a technological revolution. Scientists in various fields had continuously worked hard and made many major breakthroughs. The widespread application of new energy had solved the energy crisis. Clean energy sources such as solar energy, wind energy, and water energy had been used more efficiently, and some new types of energy sources had also been developed, such as controllable nuclear fusion energy, making energy inexhaustible. The development of artificial intelligence had made people's lives more intelligent and efficient. Intelligent robots played an important role in various fields, from industrial production to medical care, from education and teaching to household services, and they were everywhere. At the same time, Earth had also strengthened exchanges and cooperation with other planets and gradually integrated into the broader cosmic family. Humans had established scientific research bases and colonies on other planets, exploring the mysteries of the universe and looking for new living spaces.

Lin Yu and Li Qiang listened to these stories, filled with emotions. They realized that although they had left Earth, Earth had not stopped moving forward. The world was constantly developing and progressing, and they also needed to adapt to this new era as soon as possible and find their own place in this world again.

In the following days, Lin Yu and Li Qiang began to study and understand this new world diligently. They participated in various training courses to learn new scientific and technological knowledge and skills. In the process of learning new energy technology, Lin Yu encountered many difficulties. Those complex theories and formulas made him feel at a loss for a while. But he didn't give up. He used the perseverance he had accumulated during his interstellar adventures, constantly consulted materials, and asked experts for advice. After countless days and nights of hard work, he finally gradually mastered the core points of new energy technology.

Li Qiang also didn't have an easy time on the road of learning artificial intelligence. The algorithms and program designs of intelligent robots were extremely complex, and all kinds of unexpected problems might occur during each debugging. But relying on his deep understanding of mechanical and electronic technologies and the innovative thinking cultivated during his interstellar explorations, he continuously tried new methods and ideas. After failing again and again, he finally found the key to the problem and successfully solved the difficult problem.

During this process, they got to know many new friends. These friends came from different fields and had their own unique insights and experiences. There was a doctor who studied biotechnology. He shared with Lin Yu and Li Qiang the latest research achievements in gene editing technology, enabling them to have a deeper understanding of life sciences; there was also an engineer engaged in aerospace engineering. He told them about the latest progress of human interstellar exploration, which inspired Lin Yu and Li Qiang's greater curiosity about the universe. Through communication and cooperation with them, Lin Yu and Li Qiang gradually kept up with the pace of the times and also found their own development directions.

Lin Yu developed a strong interest in new energy technology. He joined a new energy research institution and was committed to studying more efficient and environmentally friendly new energy development technologies. At work, he gave full play to the experience and knowledge he had accumulated during his interstellar adventures and put forward many innovative ideas and plans. He found that during interstellar travel, there were special energy fields on some planets, and the principles of these energy fields were similar to those of the new energy sources on Earth. He applied these discoveries to his research and led the team to conduct countless experiments. During the experiment process, they encountered many technical problems, such as the stable output of energy and the high-temperature resistance of materials. But Lin Yu and his team were not intimidated by the difficulties. They continuously optimized the experimental plan and looked for new materials and technologies. After unremitting efforts, his team finally made a major breakthrough and developed a new type of solar energy conversion material. This material could increase the conversion efficiency of solar energy several times, making an important contribution to solving the global energy problem.

Li Qiang was full of enthusiasm for the field of artificial intelligence. He joined an artificial intelligence technology company and focused on the research and development of the application technology of intelligent robots. Using his understanding of mechanical and electronic technologies during his interstellar explorations, he successfully developed a intelligent robot with a high degree of autonomous learning ability. During the research and development process, he encountered the problem of emotional interaction of intelligent robots. How to make the robot better understand human emotions and needs became the biggest challenge he faced. Through in-depth research on human psychology and behavior, combined with advanced algorithms, he gave the robot more humanized emotional recognition and interaction functions. This robot could not only play an important role in industrial production, improving production efficiency and quality, but also provide various convenient services for daily life, such as chatting with the elderly, taking care of children, and doing housework, and was widely welcomed by the market.

As time passed, Lin Yu and Li Qiang achieved more and more in their respective fields. They also gradually became the promoters and leaders of Earth's scientific and technological development. However, they always remembered their original intentions and missions. In their spare time, they would recall the past with their families and friends. Every bit of their interstellar adventures became the most precious stories in their mouths. They would also tell the younger generation about their interstellar adventure stories, inspiring them to bravely pursue their dreams and explore the unknown world. They told the young people that the universe was infinitely vast and full of countless possibilities. As long as they had the courage and dreams, nothing could stop their steps forward.

In this new era full of opportunities and challenges, Lin Yu and Li Qiang interpreted the meaning of perseverance and struggle with their actions. From being confused and at a loss when they returned to Earth, to gradually adapting and integrating into this new world, and then to becoming an important force driving the development of the world, the journey has been full of hardships and sweat, but they have also reaped full happiness and achievements. They know that the road ahead is still long, and there are more unknowns waiting for them to explore. But they are already prepared. With their love for Earth and their longing for the future, they will bravely step into a new journey. In the days to come, they will continue to explore and move forward on the road of science and technology, contribute their strength to the development of Earth and the progress of humanity, and write a more brilliant chapter belonging to them.
