In the future, the sun is wrapped in a Dyson sphere by a giant company, and 100% of the energy is intercepted. The elite class live on the artificial giant sphere on the inner surface of the Dyson sphere, enjoying nearly unlimited energy and technology; while the lower class humans are abandoned on the earth, struggling to survive in the lightless, cold underground cities. However, the existence of humans at the bottom is not meaningless - the company has discovered that the human brain is the most energy-efficient and creative "biological processor" in the universe. As a result, the earth was transformed into a huge "Truman Show": every earthling was carefully arranged by the algorithm from birth to death, their dreams were harvested and used to train artificial intelligence, their emotions were compiled into parameters of the decision-making algorithm, and their lifelong struggle and creation became products consumed by the elite and the "CPU" that deciphers the mysteries of the universe.
