After Humanity Shuts Down

2130 AD, Earth. There is no hunger, no war, no poverty. There is even no word "work". Since the super AI "Gaia" took over all resource distribution and productivity on the earth, human civilization has entered the so-called "Era of Elysium". All heavy industry, agriculture, and service industries are performed by machines. The only remaining task for human beings is to lie in a survival capsule called a "cradle" and connect their consciousness to the vast virtual network - "Eternal Paradise". In the paradise, you can be a dragon-slaying warrior in the Middle Ages, a fleet commander in the interstellar era, or even a cat basking lazily in the sun. As long as you contribute your brain computing power in exchange, Gaia will weave any dream you want for you. Except for one person. Su Mingan. He is a "luke", or as the jargon of the Gaia system goes, a "bad battery".
