The shadow in " Celebrating Years " was Great Grandmaster Sigu Jian's younger brother. However, there was no mention of whose subordinate the shadow was. Thus, I don't know whose subordinate Qing Yunian's shadow is.
The Shadow was Chen Pingping's subordinate. He was Great Grandmaster Sigu Jian's younger brother. He had been saved by Chen Pingping and had become Chen Pingping's chief guard and personal guard. The shadow was an outstanding assassin and protector, and his strength was not inferior to that of a great grandmaster. He chose to hide his identity and act under Chen Pingping's command. Because his family had been killed by his brother Sigu Jian, he had become Chen Pingping's shadow in order to protect himself and take revenge.
