I am already the Archbishop of Destiny. Who do you want me to counterattack?

(If you have any weak points, blame the author!)
What should I do if I travel to the Honkai Impact world and become a contemporary of Otto Kallen and their parents? There are no plug-ins or emulators?
All we can do is take our time and apply for Archbishop?
Decades passed.
The white-haired girl who is Destiny's only S-class Valkyrie, the sister of the head of the Apokalis family, Otto's aunt, and Kallen's aunt, finally got her wish and sat on the position of Destiny Archbishop.
Then.....
The system appears...
"The Rise of Waste System has been installed. The host is requested to actively complete the system tasks and complete the rise to become the Archbishop of Destiny as soon as possible!"
"Rise up mission one, the first step to become the Archbishop of Heaven and establish authority."
"Please slap your face to mock your eight-year-old brother, who will be the head of the Apocali family appointed by the archbishop in the future, to establish his prestige! (Otto's father)."
The white-haired girl looked at her 40-year-old brother, the head of the Apokalis family, who had been beaten to death by her.
I'm the Archbishop of Destiny on horseback and you tell me to rise?
Kallen: Hug from my aunt!
Otto: Aunt...Hello, Aunt...
