Xu Qinglang and Xu Zhiyuan came with gifts and were dressed very formally.
"Mr. Luo promised my father before the competition that he would teach Zhiyuan the Taiyi Divine Needle. After the competition, he reaffirmed that he would keep this promise. Therefore, today, as his father, I have brought Zhiyuan to formally acknowledge him as a mentor." After entering, Xu Qinglang bowed and stated his purpose, "The Taiyi Divine Needle is a divine art in the field of traditional medicine; learning it requires seriousness. Therefore, I've brought Zhiyuan today to perform the ceremony of acknowledging a mentor."
Luo Ziling had guessed the purpose of the Xu family father and son's visit today, so he wasn't surprised when he heard Xu Qinglang say this.
