Gu Jin ignored her. Logically speaking, what Gu Aihan did was never her concern.
Four elements at the age of 22? Might be a prodigy, but compared to Gu Jin...Gu Jin preferred to remain silent.
With her one element at emperor rank, two at advanced rank, and one at intermediate rank...Gu Aihan was just like a child to her.
Nan Bei however had a different plan, she suddenly shouted,
"Gu Jin I want to challenge you."
Gu Jin paused and spat out two words, "Not interested."
Nan Bei gritted her teeth and tried to provoke Gu Jin, "What scared already? You are pathetic!"
Gu Jin rolled her eyes, if she didn't know what Nan Bei was planning then her years of staying in the mafia organization would be a waste.
Was Nan Bei taking revenge on Gu Aihan's behalf? Maybe Nan Bei will present it like that.
