While Xinzi set the stage for his largest breakthrough so far, in the White Immortal sect, Zi Yao read a letter.

"Aunt, my sincere apologies, but I'm starting to feel stifled in the White Immortal sect. I can take my wine wherever I go, so you aside there's nothing for me there. But nowadays, you've become the primary source of my suffocation. True, I'm not as useless as I try to act, but my ambitions by no means can compare to yours. Zuixian doesn't want to resent his only close kin, so Zuixian is going on a trip—to a place that never fails to entertain me. See ya." The letter ended here, and Zi Yao's hand clenched around the paper, burning it into ashes.
