"Greetings, Teacher Chu and Teacher Gu!"
Shu Zi Feng greeted Chu Jiaxue and Gu Yuexi properly and respectfully.
Although Chu Jiaxue and Gu Yuexi had known for a long time that Lin Chen had once saved a young girl and took her in as his disciple due to a fortuitous coincidence, taught her the Heavenly Sword technique, and gave her a great opportunity, they found out from Yao Xuanji that this young girl, after all these years, had surpassed them and directly become a Da Luo Venerable.
Chu Jiaxue and Gu Yuexi, in the sect, were called senior sister out of respect for their strength and status, but this is the first time someone has addressed them as teacher. They found this unfamiliar at first.
The one bowing and addressing them as teachers, was, in fact, a Da Luo Venerable!
