Beyond Observation: the Anthropocene

In 2100 AD, the earth's environment was on the verge of collapse. Humanity formed the Earth Alliance and accidentally came into contact with the top civilization in the galaxy - the Observer Civilization. This civilization gave up its physical body and turned into a fluid life, ruling the roost with observation and consciousness technology. However, due to its incomplete body, it secretly used human beings as samples in order to create a perfect new body. The top leaders of the alliance made a deal with it and allowed it to release detectors and use the human spirit as the experimental subject, causing a huge disaster. At the same time, the Devourer civilization dozens of light years away covets the earth polluted by industrialization and is slowly attacking. In order to preserve the experimental samples, the observers imparted technology to a limited extent, but strictly prohibited humans from developing high-energy sonic weapons that could restrain themselves. After the alliance's shady story was exposed, a civil war broke out and eventually merged into the Global Alliance. After hundreds of years of development, human beings have spread their power throughout the solar system and defeated Devourer in a bloody battle in the Kuiper Belt. After the war, humans saw through the Observers' weaknesses, secretly created sonic weapons, and even formed an alliance with the defeated Devourers to finally defeat the Observers. The three major civilizations of humans, Devourers, and Observers thus formed the tripartite pillars of the Milky Way. A magnificent human era was officially opened based on observation.
