To Save the World, the Doctor Has to Copy the Homework!

As a total newbie at games, how am I supposed to save the world after I transmigrate into the world of Arknights?

Recruit every Operator to Rhodes Island, and then you can copy their homework perfectly!

Set up the equation.

Plug in the numbers.

Recruit every Operator to Rhodes Island = Save the world!
