Who is the spirit walker, the shadow Gemini?

The master's journey to the spiritual world without trace is a fantasy online novel. In the 56th chapter of the novel, it tells the story that Zhang Yuanqing was suddenly struck by lightning after learning the identity of the shadow Gemini. I never imagined that the non-mainstream master was actually Zhang Yuan Qing's father's comrade-in-arms, a shadow Gemini. So, Zhang Yuanqing, who is not afraid of death, went directly to Master Nontrace for a showdown. When he heard the shadow of the fierce sun from Bird's mouth, the Buddha statue representing the mood of Master Nontrace instantly turned into a dazzling King Kong, and Zhang Yuanqing could trample to death in one breath every minute. The author of this novel is a small newspaper seller, serialized at the starting point.
