The Last Tower

--- In 4000 AD, the last human creation on earth stood on the Antarctic ice sheet. Inside the tower is a digital intelligence that never stops thinking. It carries seven thousand five hundred years of human civilization, but it cannot carry human desires—those desires have long since joined the virtual world with the last batch of consciousnesses, and have fallen silent in the ocean of data. Outside the tower, the solar system is dotted with human relics: collection stations floating in the orbit of Jupiter, antenna arrays in the hollows of Mars satellites, automatically operating mining facilities on asteroid belts... They are still operating, but they have long since lost their owners. Until one day, this intelligent body, which is neither tired nor eager, made a decision: Continuing mankind's unfinished interstellar project. The consciousness that has been dormant for hundreds of years begins to awaken, and seventeen "people" will once again set foot on the universe as machines. What they have to face is the unknown starry sky, the long loneliness, and a question without an answer—— When humans disappear, will their creations still be considered humans? --- This is the story of a tower and how civilization continues in silence.
