Deductive

Beneath the bright moonlight and the tranquil veil of night, Jun Wu Xiao and his companions were on their way home. There was no rush, so they proceeded slowly, contemplating what Jun Wu Xiao had shared. Chu Wu asked in surprise:

"I never expected you to speak such words. I thought that after such a long seclusion in cultivation, you'd remain an immature old child forever."

Jun Wu Xiao's expression darkened upon hearing this, losing the calm demeanor he had earlier. He retorted:

"What do you mean? Why shouldn't I be able to speak such words?"

Seeing Jun Wu Xiao revert to his usual demeanor left Chu Wu at a loss for words. He understood that Jun Wu Xiao's behavior could change depending on what he was doing, but he hadn't expected such a swift shift in attitude.
