Chen Xuan couldn't help but laugh wryly.
Oh right!
Xuan Er is at the First Grade of Spirit and Martial Dual Cultivation, how could he not know that Cosine is at the entrance?
It seems he has disrupted something.
"What's the matter?" Xuan Er asked, without any trace of anger.
Because Cosine had been standing outside the door for a long time, hesitating with a few attempts to knock on the door, he knew all of it.
But..... maybe Chen Xuan's arrival was actually a blessing in disguise.
"By the way, disciple wishes to ask about the First Grade realm."
"First Grade?"
Xuan Er raised his eyebrows slightly in confusion, "Why are you asking about this? You're only Third Grade, and the First Grade is still far off for you. Knowing too much isn't good!"
It wasn't that he was unwilling to talk, but it's too distant for him now. It's not too late when he reaches the Second Grade.
