"Oh, yes, yes, Sister Chunhe is right."

San Shu's mood darkened. "Princess, not every family can afford to raise a child."

"In my family, including myself, there are five children. After my mother left, my father remarried and had four children with my stepmother. Because my stepmother didn't like me and thought I only knew how to eat and couldn't do any work, I was sold into the palace."

Xiao Xi stopped, patted San Shu's legs, and said boldly.

"Sanshu, from now on I'll take care of you, I'll never sell you."

"Oh dear, this servant thanks you, Princess."

"Uh-huh"

Xiao Xi'er turned around and continued walking towards the palace school.

"Grandpa Sanshu, can you please call me Math?"

"If the princess wishes for me to be called 'Suanshu' (算数), then I will be called 'Suanshu'."

"Really?"

"real"

"Then how about you be called Arithmetic from now on?"

"Good princess"

And so, the number three got a new name—arithmetic.

"Princess, why did you decide to name this servant?"

"A few days ago, Erguo and I listened to a lecture by a teacher, who said he taught arithmetic."

"And then I wrote it down~"

"Isn't it amazing?"

"The princess is amazing!"

"whee"

As Xiao Xi walked, she realized someone was missing, so she asked Chunhe as she walked.

"Sister Chunhe, why haven't I seen Sister Xiaju these past few days?"

Xia Ju is teaching Qiu Mei manners.

"AoAo"

Along the way, Xiao Xi'er talked to Suanshu and Chunhe.

It took quite a while to get to the palace school, and by the time we arrived, we were already late.
