The emperor had sent many imperial physicians to check Lan Ruozhu's physical condition. When Lan Ruozhu was still in the mansion, the emperor wanted the imperial physician to cure the former.
Then he sent Lan Ruozhu to his fief after learning the severity of Lan Ruozhu's condition. Otherwise, the emperor would feel uneasy letting Lan Ruozhu go to the county.
Furthermore, before Princess Lan died, she set up a scheme to use public opinion to pressure the emperor into letting Lan Ruozhu go to his fief.
The emperor and the other forces never expected Lan Ruobing to reincarnate after her death. Moreover, Su Binglan could now cure Lan Ruozhu and restore his health. She could also help him with taking revenge.
She revealed a determined expression after thinking of this. "But, if you acknowledge me as your adopted sister to the people, you must have an explanation to stop everyone from becoming suspicious."
