When modern times and ancient times are in two parallel time and spaces, the two eras separated by hundreds of years can actually be connected and overlap. People in the two eras are inextricably linked to each other: are they the same person? Or are they two comrades who can cherish each other even though they are in different eras? How could he, who was in modern times, and he who was in ancient times, be able to keep in touch with each other at all times and communicate about each other's great plans? One was a chess player in ancient times, and the other was a chess player in modern times? And what role do "she" and "her" play in the world of "he" and "him"?
Purpose: To tell a story that has been told millions of times from the perspective of parallel time and space
