I want a novel by Lu Xun, The History of Man, the full text.

The full text of Mr. Lu Xun's short story, The History of Man, is as follows: The history of mankind was also the history of mankind. Since ancient times, mankind had been constantly developing and progressing. The development of human society had gone through many storms and ups and downs, as well as many pains and pleasures. In the early days of human history, people lived a life of hunting and gathering. Through exploration and discovery, they continued to explore new places in search of new resources. As humans progressed, they began to build houses and cities, and they began to master more knowledge and skills. People began to use tools, thoughts to solve problems, and art to express their emotions. As time went on, humans began to master more technology. They built more machines and equipment to improve work efficiency. People began to use electricity and the Internet to connect and exchange ideas with each other. People no longer lived a life of hunting and gathering, but turned to a more advanced lifestyle and enjoyed the convenience brought by technology. However, the progress of mankind also brought many problems and challenges. Problems such as environmental pollution, resource scarcity, and climate change made people start to think about how humans should deal with these problems. People started to pay attention to environmental protection, started to reduce waste, and started to look for ways of sustainable development. The history of mankind was a history of constant evolution and progress. In this process, humans experienced a lot of pain and happiness, as well as many challenges and opportunities. We must learn to cherish the present and constantly explore the future to make human history better.
