In 2085, the space city "New Chang'an" in Mars orbit faced an unprecedented crisis.
Lu Xiaoyu, a 12-year-old mechanical genius, went to Area B-72 under the guidance of his father's last words, and met the mysterious girl A Yue on the way. Together, the two embark on a journey full of puzzles, dangers and adventures.
As they gradually uncovered the secrets of the "Star Railway," they discovered that it was not only an ancient mechanical track, but also carried mysteries closely related to ancient precision instruments, astronomy, and long-hidden historical heritage.
Going deep into this track that connects the past and the future, ancient wisdom and modern technology, friendship, responsibility and courage will become their only reliance.
And their choice will also determine the future of the entire space city.
Purpose: Inherit traditional culture
