12-Year-old girl Lin Xiaoxing pressed the button of the quantum teleportation capsule and took her father's relics with her to a space city called the Möbius Strip.
She would never have thought that her father's relics would be the key to the interstellar mystery city.
Deep in the lunar orbit, the Möbius ring-shaped silver city is disintegrating - the out-of-control mechanical octopus bites the lost submarine, the frozen alien computer hides ancient codes, and the helium-3 reactor that keeps the city running only has 12 hours left!
Here, on the streets where weightlessness and gravity alternate, she will meet a Martian girl who can program mycelium, a lunar boy who can dismantle starships, and a robot RC-07 who always likes to speak in a 20th-century radio accent.
They must travel through the extremely cold ice crystal land, the mouth of the deep sea monster, the ultra-high temperature nuclear fusion factory, and solve the mystery of life and death in the starry sky library filled with ancient books.
This time, the future of mankind is not on the earth, but on the Möbius strip that connects end to end - are you ready to embark on this first lesson in the universe that subverts cognition?
Intention: Let all life become a symbiosis of light
