The Old Dynasty Is Gradually Declining, the New Dynasty Is Coming, and the Times Are Changing.

This fanfic about Arknights is a new one, so please bear with me. At the beginning, some of the original plot may be mixed in. Those who are familiar with it can skip it. It will gradually get better later. On the continent of Terra, the Source Stone and natural disasters continue to destroy everything, but humans always survive tenaciously. However, various countries and organizations are infighting and fighting openly and secretly. In this predicament, can Rhode Island, an organization that strives to find a way out for the infected, go further and better, and what kind of difficulties are waiting for them? (Warm reminder, the plot mainly refers to the game "Arknights". If you don't understand, you can watch the plot of the game.)
