Ringworld

What was it like to cross over and become an AI? Li Wenyuan, who was hit by the meteorite, managed to know that feeling.

You're saying that Wise Machines don't need this? Sorry, psychic machinery or something is in production now." "Interstellar colony? How about building a ringworld?" This was a story of kingdom building, which was also a story of human exploration of the universe from the past. There were space wars, interstellar expeditions, civilizational observations, and galactic epics. "So..." Some years later, facing the disaster that was about to sweep across the galaxy, the unmanned fleet controlled by Li Wenyuan stood out passively. "They all think I am a lost empire, and I can only go and do what a lost empire should do."
