In ancient times, a guard named "changpan warrior" was brought to the city by a young master named "kendo." The young master was kicked out of the city and taken to a wooden box. The box contained the sword that the young master had given to the old master, as well as a brocade cloth that the old man had given the new master. The old master had taken nothing with him, and the tattered box of the sword had been given to zhongli, who had been expelled from the city. The new master has brought the sword to jun hall, and changpan asks the old guard if it is necessary for him to track down the two men. .
