Luo Yan, who has been able to draw mysterious symbols since he was a child, unexpectedly discovered a connection with the bronze keys passed down by his family and strange dreams through photos of Luoyang cultural relics in college.

A game revolving around the power of arithmetic beads and rewriting destiny suddenly started in front of him.
