Arknights- Tundras Empire

[This is my first work. Because I felt deeply disappointed by the plot of the original story, I tried to write my own fantasy. It's a story I wrote step-by-step, so there might be logical inconsistencies.]

The content is largely a heavily modified version of Arknights' main storyline. Characters may deviate from their original designs, but they definitely won't be severely altered (probably?).

[The character is reborn as an old Ursus Eagle Bannerman of Terra with his memories intact, emmm…]

The suffering of this land has never changed. Rather than compromising and indulging in the sugar-coated luxury of so-called nobility and pursuing unrealistic stability, it is better to break free from a decadent life, join hands with idealists in the struggle, build a future with the weapons in our hands, and open up the way forward with the sword of truth.

However, the road ahead is long and arduous, and the journey is fraught with difficulties…

Who? Whom will be saved?
