There could be Soldier: 76. Since they are all part of the Overwatch team, he might be involved in the story in relation to Mercy. Maybe she has to heal him during a battle.
There were two main reasons for Fan Ruoruo's leniency. First of all, Fan Ruoruo had reverence and respect for the Qing Emperor because she was the Qing Emperor's adopted daughter. This special status gave her a deep reverence and respect for the Qing Emperor. She believed that as the ruler of the Qing Kingdom, the Qing Emperor had irreplaceable authority and status. Thus, she would maintain a certain distance and caution when facing the Qing Emperor. She would avoid making overly impulsive or radical moves.
Secondly, Fan Ruoruo was a kind and rational woman. She understood that in power struggles, overly intense confrontations often led to unpredictable consequences. Therefore, she chose to deal with the problem rationally and calmly, rather than blindly venting her emotions or taking extreme actions. Fan Ruoruo understood that excessive violence could bring more harm and pain, so she chose to show mercy and not kill the Qing Emperor directly. This could also be her tolerance and forgiveness for the Qing Emperor. She hoped to change the Qing Emperor's behavior through mercy and make him realize his mistakes and correct them. In short, Fan Ruoruo's mercy was based on her respect and respect for the Qing Emperor, as well as her consideration of the kindness and rationality in her heart.
Yes, 'Mercy Black' is based on a true story. It often takes real - life events and weaves them into a horror narrative to create a more chilling and believable experience for the audience.
