Lin Ye, a graduate student in the Department of Archeology, encountered a strange blue light while appraising the Shang and Zhou astrolabe, and woke up to find that he was Ryan White, an international student from the Kingdom of San Lorenzo.
While sorting out his belongings, Lane found contradictory diary records, suggesting that the original person might be involved in some dangerous research. He also noticed unusual changes in his pocket watch.
Through the curriculum and maps of Clover School, Ryan realized that this was a world similar to 19th-century Europe but with the double-moon celestial phenomenon, and noticed that people deliberately avoided the "seventh constellation".
