Arknights? Yesterday's Arknights!!

"I want to do something for this world, for the people, for everyone."
An Xin still remembers the oath he took when he joined the police force.
Even after he transmigrated to this world, it was the same; in each game, he made countless choices, and finally changed the world.
"Twenty years ago, I helped Wei Yanwu; two years ago, I helped Talulah; I saved Alina, creating a new timeline."
On that day, the Black Serpent Talulah saw Alina and the warrior Talulah alive and broke down in tears in front of everyone.
"At that time, Skadi reached out her hand to me and told me she was in pain and asked me to kill her. I chose to assimilate with her and become a part of her."
Later, Skadi, the newborn of the deep sea, and Skadi, the deep-sea hunter, forced me to choose one of them. I said I didn't want to give up either of them.
"One day in Syracuse, I met a little girl who was homeless. She said she had no home, and I said I could be your brother, and we would be family."
When we were in Longmen, she found me, but there was someone who looked exactly like her, only slightly older.
The game continues...
Arknights? This is Yesterday's Arknights!
All regrets will be made up for.
