"Little brother"
"Liu'er, that's your senior brother, not some little brother."
"I understand, master"
"Master, how long have I been following you, little brother?"
"You girl can't remember what you said. In this Wanli Heaven, there are only Wanfang Yazun Sujian, your senior brother, and no little brother."
"Yes, Master"
"Then Master, why does the little senior brother have to be called the little brother, even though he looks so much older than the little brother?"
"My little brother hasn't changed yet, so why is there another little senior brother?"
Hey... I, my apprentice, must be stupid, right?
