At some point in the future, mankind would have completed space exploration and established multiple planetary bases. However, with the continuous development of science and technology, humans were also facing more and more problems. Energy shortage, environmental pollution, resource scarcity and other problems plagued mankind. In order to solve these problems, humans began to explore new sources of energy and develop new technologies to protect the environment. The protagonist of the story was a young engineer named Li Hua. Li Hua had been curious about technology and the universe since he was young. He often sneaked into the laboratory to study all kinds of strange machines. His parents didn't support his hobby and thought that Li Hua should spend his time on more meaningful things. However, Li Hua did not care about his parents 'opinions. He firmly believed that technology could help mankind solve many problems and make mankind stronger. Li Hua majored in computer science at university. He became an excellent engineer through his own efforts. His job was to design and maintain the control system of the spacecraft. During a mission, Li Hua discovered a new technology that could clean the Earth's environment. This technology could make the earth more green and reduce pollution, allowing humans to have more time to pursue other hobbies. Li Hua decided to hand this technology over to the government so that the government could promote it in a comprehensive manner. However, this technology was not easy to implement and required a lot of financial support and technological breakthroughs. Li Hua decided to start his own environmental protection technology company. He used his experience in the field of science and technology to develop many new technologies and sell them in the market. His company quickly became one of the most popular environmental technology companies on Earth. However, Li Hua's company was not satisfied with this. He wanted to delve deeper into the universe and explore more planets. Hence, Li Hua resigned and began a space exploration journey with his team. They began their journey of space exploration on a huge spaceship carrying all kinds of advanced technological equipment. On their journey, they discovered some strange phenomena. Some planets had very harsh environments, but their energy sources were very abundant. Other planets have environments that are very suitable for human habitation, but their energy sources are very limited. Li Hua and his team began to study these phenomena and found some possible causes.
