The Emperor Race knows no family!
During his second life as the Human Emperor's Son, Yang Xiao had felt this with stark clarity.
Back then, his physical body had been sealed. Aside from his father in that second life, the Flame Emperor, who showed him some concern, all his other siblings—even his own birth mother—treated him with cold indifference.
Later, when he became the Human Race Medicine Ancestor through his own efforts and gained the respect of the entire Human Race, these same siblings suddenly became much warmer toward him.
However, their goal was to subdue him and use him for their own purposes.
Yang Xiao, naturally, refused.
After his refusal came blatant assassinations, open slander, and all sorts of suppression. It was as if they weren't his blood relatives at all, but complete strangers.
No. If they were truly strangers, they certainly wouldn't have acted this way.
