About three hours before the dust settled at the battle of the Chengde Qianhu Office, a group of hurriedly riding knights arrived outside the Chaoyang Gate of Beijing.
These people were all dressed in armor that reached their waist, with battle robes underneath, all dressed up in the attire of a 'feathered rider'. (Feather, in ancient times military document, inserted bird feathers to indicate emergency.)
However, after they rushed in, they did not head towards the Ministry of War and the Dudu's mansion, but instead rode into an unassuming civilian residence on the way.
This civilian residence was empty, with only a man dressed in a scholar's robe and wearing an iron mask, waiting with his hands behind his back.
After the group of riders gradually rode in, the one at the forefront lifted the sun-shading hat from his head.
