In the library.

A girl is cleaning the room with the sweeping robot.

A sweeping robot moves around on the ground. It straightens forward, slows down when it is about to hit the wall and then it slowly turns its tumbling body and cleans in other directions. It moves forward slowly, stopping in front of a pair of slippers, hesitant to change direction.

Eve stepps over the sweeping robot and carefully takes out the book from the bookcase. Although this library is just a small study in this house, the stored books are very precious.

Today, as humans are highly dependent on electronic technology, many people still tend to use paper for office work. Eve takes down fifteen books with one hand, and she spends 0.1 seconds scanning and confirming that these books are related to Mada's programming theory major. So she cherishes them on the desk and puts them back in place after she finishes cleaning the bookcase.

0.1 second. It is too short for humans to even perceive pain. But it is enough for robots to complete tens of thousands of calculations. She thought. Fortunately, I am a bionic robot. Otherwise, how much time should it take for a human girl to sort out a library?

“Welcome back.” The certification prompt sounds suddenly.

Eve pauses to clean with surprise and she walks out of the room.
