Two rings with simple styles allow Wu Xie to travel between modern times and the warlord period.
During the period of warlord fighting, Wu Xie became a disciple of Er Er Hong in order to find shelter, joined Er Er Hong's sect, and fought with Er Er Hong and Zhang Qishan;
In modern times, Korean actor Hou Zhun came to tell Wu Xie that he was a descendant of the Park family, and that the two rings that could travel through time and space were treasures that their family had always guarded.
What are these two rings? Why can we travel through time and space? Why was it sent to Xie Yuchen's home as an ordinary express?
