Gu Ning felt Yuan Yilin was overestimating herself if she genuinely intended on driving a wedge between Master Leng and her.
Yuan Yilin's ploy would only work if Gu Ning and Master Leng were on average terms and she was close friends with Yuan Yilin.
Gu Ning got it spot on. Yuan Yilin hoped to drive Gu Ning and Master Leng apart. Even though she did not think they were awfully close, she could not stand seeing them on good terms.
"Senior Yuan," replied Gu Ning nonchalantly.
"Who did you come with?" asked Yuan Yilin.
"I received an invitation," replied Gu Ning before she said apologetically, "Senior Yuan, my apologies. I am in the middle of a conversation with Grandpa Leng, so I can't chat. It is rude to interrupt a conversation to begin with. Also, it is a huge disrespect towards Grandpa Leng."
