Lin Wu, a time-blind girl, accidentally obtained an ancient Shu time crystal at the Jinsha ruins. When being hunted by the Time and Space Administration, she actually traveled to Chengdu in the Republic of China. Her shadow reflected the bronze mask, and the whisper of "Find the ninth sacred tree to prevent the collapse of time" rang in her ears. On one side is the secret protection of the clock watcher, on the other side is the resource plundering by the official organization. Lin Wu, with his broken memories, explores the truth of the ancient Shu civilization in the folds of time, and also reveals his secret connection with the sacred tree.
