The Zhao family ancestors obtained an opportunity in the Imperial Family Secret Territory, which made them acutely aware that if used well, the Secret Territory could keep the Zhao family strong forever. Thus, they left an ancestral instruction, requiring their descendants, after cultivating to the Gold Core Stage, not to go to other places but must enter the Imperial Family Secret Territory. On the one hand, they had to guard the Secret Territory for generations of the Zhao family, ensuring no other person or organization could take it away. On the other hand, they hoped someone could find even greater opportunities within, and thereby push the strength of the Zhao family a step further.
